    OPINION
    HORN, J.
    Protestor, Vectrus Services A/S (Vectrus), filed its pre-award bid protest complaint
    in the above-captioned bid protest challenging the offeror eligibility requirements included
    in Request for Proposals No. FA2523-21-R-0001 (the Solicitation), issued by the United
    1 This Opinion was issued under seal on February 19, 2023. The parties were asked to
    propose redactions prior to public release of the Opinion. This Opinion is issued with the
    redactions that the parties proposed in response to the court’s request. Words which are
    redacted are reflected with the notation: “[redacted].”
    States Space Force, 21st Contracting Squadron, Detachment 1 (Space Force),
    organizationally located within the United States Department of the Air Force (Air Force),
    after filing a protest at the United States Government Accountability Office (GAO), Vectrus
    Services A-S, B-420527 et al., 
    2022 WL 1639491
     (Comp. Gen. May 18, 2022), discussed
    below. The Solicitation at issue in the above captioned bid protest was issued by the
    Space Force located in Copenhagen, Denmark.2 The Solicitation was for a Base
    Maintenance Contract to be performed at Thule Air Base which protestor describes as
    the “northernmost installation” operated by the Department of Defense. Thule Air Base is
    located in Greenland, within the Kingdom of Denmark (Denmark).3
    In its bid protest complaint, protestor stated that it is “challenging improprieties in
    Request for Proposals [RFP] No. FA2523-21-R-0001,” (alteration added), as well as
    challenging “the Agency’s determination that Vectrus, the awardee on the incumbent
    contract, is ineligible to compete for award of the BMC [Base Maintenance Contract]
    under the RFP’s unlawful terms because, although it is incorporated in the Kingdom of
    Denmark (‘KoD’), it is a wholly owned subsidiary of a U.S. company.” (alteration added).
    According to protestor, the Space Force “has restricted competition under the current
    RFP to offerors more than 50 percent owned by, and subject to the decisive influence of,
    Danish or Greenlandic individuals or entities,” and those “eligibility criteria prevent any
    U.S.-owned or -controlled company—or indeed, any company that is owned or controlled
    by a citizen of any country other than Denmark or Greenland—from competing for award.”
    Protestor further alleged that the Space Force “determined Vectrus ineligible to participate
    in the re-competition of its incumbent contract,” and that the Space Force “attempts to
    justify excluding Vectrus from competing for the BMC by reinterpreting the terms of an
    international agreement based solely on a nonbinding political commitment made by the
    United States in recent diplomatic correspondence for the sake of comity with the KoD.”
    Protestor’s bid protest complaint alleged that the Solicitation’s “restrictive eligibility
    criteria,” limiting competition to Danish- or Greenlandic-owned and controlled companies,
    violate “the Competition in Contracting Act of 1984 (‘CICA’) and its implementing
    regulations” which, according to protestor, provide that “agencies may not restrict
    competition for federal contracts unless a statutory exception applies.” (alteration added)
    2Protestor and defendant both inconsistently referred to the contracting agency as the
    Air Force and the Space Force. The court refers to the contracting agency in the above
    captioned bid protest as the Space Force, and the contracting activity for the earlier
    contract, which was awarded before the formation of the Space Force, as the Air Force.
    Moreover, certain individuals are identified by their affiliation with the Department of the
    Air Force, not the Space Force, such as members of the Air Force Office of the General
    Counsel.
    3 The Market Research Report prepared by the Space Force in anticipation of the
    Solicitation at issue in the above captioned bid protest, which was included in the
    Administrative Record, describes Greenland as “a self-governing entity of the Kingdom
    of Denmark.”

    (citing 
    10 U.S.C.A. § 3201
    (a)(1) (2022);4 FAR 6.101(a) (2022), FAR 6.301(d) (2022)).
    Protestor’s complaint cited to one statutory exception to the Competition in Contracting
    Act’s competition requirements, “where ‘the terms of an international agreement or a
    treaty between the United States and a foreign government . . . have the effect of
    requiring’ the restriction.” (ellipsis in original) (quoting 
    10 U.S.C.A. § 3204
    (a)(4)).
    Protestor’s complaint asserted two counts. Count One alleged that the Space
    Force’s restriction of competition to Danish or Greenlandic companies was “arbitrary,
    capricious, an abuse of discretion, and contrary to law.” Count Two alleged that the Space
    Force’s “decision to exclude Vectrus from competition” pursuant to the Solicitation’s
    requirements was “arbitrary, capricious, an abuse of discretion, and contrary to law.”
    Protestor requested a declaratory judgment and an injunction “to immediately reinstate
    Vectrus in the competition” as well as “to remove restrictions on competition not required
    by the terms of any international agreement” from the Solicitation. Defendant filed a
    motion to dismiss protestor’s complaint for lack of subject matter jurisdiction pursuant to
    Rule 12(b)(1) of the Rules of the United States Court of Federal Claims (RCFC) (2021).
    The parties also filed cross-motions for judgment on the Administrative Record pursuant
    to RCFC 52.1 (2021). All the motions have been fully briefed and the court held oral
    argument. Due to the urgency of the Solicitation and award process for the Base
    Maintenance Contract, as represented by the United States to the court and the
    protestor’s intention for a speedy resolution of the case, the court issued an oral decision
    on the motion to dismiss and cross-motions for judgment on the Administrative Record.
    This Opinion memorializes the oral decision provided to the parties.
    BACKGROUND
    Protestor Vectrus described itself as “incorporated under the laws of the KoD” and
    as “a subsidiary of Vectrus Systems Corporation (‘VSC’), which is incorporated under the
    laws of the state of Delaware,”5 (alteration added), but alleged that its “physical address”

    10 U.S.C. § 2304
     (2018) was moved to 
    10 U.S.C.A. §§ 3201
    , 3203 (2022),
    and 3204 (2022) by the William M. (Mac) Thornberry National Defense Authorization Act
    for Fiscal Year 2021. See 
    Pub. L. No. 116-283, § 1811
    , 
    134 Stat. 3388
    , 4164-67 (2021).
    5 The Statement of Facts, prepared by Contracting Officer Patrick R. King for protestor’s
    earlier protest of the Solicitation at the GAO which is included in the Administrative Record
    in the protest in this court, states that protestor “was established on April 23, 2014 and is
    100% owned by Vectrus Systems Corporation of Colorado Springs, Colorado.” The
    Contracting Officer’s Statement of Facts further refers to another corporation, Inuksuk
    A/S (Inuksuk), which also filed a protest at the GAO, and the Statement of Facts indicates
    that “the basis of the Inuksuk protest is exactly the same as the VS [Vectrus] Protest
    although the titles of the allegations differ slightly.” (capitalization in original; alteration
    added). Moreover, the Contracting Officer’s Statement of Facts states that Inuksuk “was
    established on February 9, 2022 and is 50-66.66% owned by Permagreen Greenland A/S
    and 33.33-49.99% owned by Vectrus Services Greenland Aps.” As of this Opinion,
    Inuksuk remained an offeror in the competition for the Thule Base Maintenance Contract.
    3
    is in Copenhagen, Denmark. Protestor alleged that as “the successor-in-interest to Exelis
    Services A/S (‘Exelis’),” “Vectrus[6] is currently performing under the incumbent Contract”
    for the Base Maintenance Services at Thule Air Base, which was due to expire on
    September 30, 2024, “if the Agency exercises all option periods,” unless extended.
    (footnote added).
    The History of the Relationship Between the United States, the Kingdom of
    Denmark, and the Government of Greenland, Including the Thule Air Base (Pituffik)
    The above captioned bid protest involves the interpretation of a series of formal
    international agreements and other forms of communications between the United States
    and Denmark relating to the use of military facilities in Greenland by the United States
    military. As stated in protestor’s complaint, “[o]n April 27, 1951, the United States and the
    KoD signed an ‘Agreement’ ‘pursuant to the North Atlantic Treaty, concerning the defense
    of Greenland,’ (the ‘1951 Agreement’).” (alterations added). Both protestor and defendant
    acknowledged the 1951 Agreement as a binding agreement between the United States
    and Denmark. The 1951 Agreement, which entered into force on June 8, 1951, attached
    to protestor’s complaint and included in the Administrative Record in the above captioned
    bid protest, provides at Article II, in relevant part:
    In order that the Government of the United States of America as a party to
    the North Atlantic Treaty may assist the Government of the Kingdom of
    Denmark by establishing and/or operating such defense areas as the two
    Governments, on the basis of NATO defense plans, may from time to time
    agree to be necessary for the development of the defense of Greenland and
    the rest of the North Atlantic Treaty area, and which the Government of the
    Kingdom of Denmark is unable to establish and operate single-handed, the
    two Governments in respect of the defense areas thus selected, agree to
    the following:
    (1) The national flags of both countries shall fly over the defense
    areas.
    (2) Division of responsibility for the operation and maintenance of
    the defense areas shall be determined from time to time by
    agreement between the two Governments in each case.
    (3) In cases where it is agreed that responsibility for the operation
    and maintenance of any defense area shall fall to the
    Government of the United States of America, the following
    provisions shall apply:
    6The entry for protestor Vectrus on the Danish Central Business Register, included in the
    Administrative Record in the above captioned bid protest, provides that protestor’s legal
    name is Vectrus Services A/S, that its address is in Nuussuaq, Greenland, and that its
    “Business type” is “Aktieselskab.” (capitalization and emphasis in original). The Danish
    Central Business Register entry for protestor does not indicate that protestor is a
    subsidiary of any corporation.
    4
    (a) The Danish Commander-in-Chief of Greenland may attach
    Danish military personnel to the staff of the commanding
    officer of such defense area, under the command of an officer
    with whom the United States commanding officer shall consult
    on all important local matters affecting Danish interests.
    (b) Without prejudice to the sovereignty of the Kingdom of
    Denmark over such defense area and the natural right of the
    competent Danish authorities to free movement everywhere
    in Greenland, the Government of the United States of
    America, without compensation to the Government of the
    Kingdom of Denmark, shall be entitled within such defense
    area and the air spaces and waters adjacent thereto:
    (i)     to improve and generally to fit the area for military use;
    (ii)    to construct, install, maintain, and operate facilities and
    equipment,        including       meteorological        and
    communications facilities and equipment, and to store
    supplies;
    (iii)   to station and house personnel and to provide for their
    health, recreation and welfare;
    (iv)    to provide for the protection and internal security of the
    area;
    (v)     to establish and maintain postal facilities and
    commissary stores;
    (vi)    to control landings, takeoffs, anchorages, moorings,
    movements, and operation of ships, aircraft, and water-
    borne craft and vehicles, with due respect for the
    responsibilities of the Government of the Kingdom of
    Denmark in regard to shipping and aviation;
    (vii) to improve and deepen harbors, channels, entrances,
    and anchorages.
    (c) The Government of the Kingdom of Denmark reserves the
    right to use such defense area in cooperation with the
    Government of the United States of America for the defense
    of Greenland and the rest of the North Atlantic Treaty area,
    and to construct such facilities and undertake such activities
    therein as will not impede the activities of the Government of
    the United States of America in such area.
    Agreement Between the Government of the United States of America and the
    Government of the Kingdom of Denmark, Pursuant to the North Atlantic Treaty,
    Concerning the Defense of Greenland, Den.-U.S., art. II, at 2-5, April 27, 1951, T.I.A.S.
    No. 2,292 [hereinafter 1951 Agreement] (capitalization in original). The 1951 Agreement
    further provides at Article VI: “The Government of the United States of America agrees to
    cooperate to the fullest degree with the Government of the Kingdom of Denmark and its
    authorities in Greenland in carrying out operations under this Agreement.” 
    Id.
     art. VI at 9.
    The 1951 Agreement also states at Article XIII, at paragraph (2): “Questions of
    5
    interpretation which may arise in the application of this Agreement shall be submitted to
    the Minister for Foreign Affairs for the Kingdom of Denmark and to the United States
    Ambassador to Denmark.” 
    Id.
     art. XIII at 13. The 1951 Agreement is the foundational
    document of the United States’ military operations in Greenland and provides the
    framework for the later agreements and the ongoing diplomatic relationship between the
    United States and Denmark concerning the United States’ military presence in Greenland,
    including at Thule Air Base.
    The Administrative Record in the above captioned bid protest includes a letter,
    dated July 19, 1956, from Frederick Jandrey, Chargé d’Affaires at the United States
    Embassy in Copenhagen, to Erling Kristiansen, “Assistant Under Secretary of State” of
    the Danish Ministry of Foreign Affairs. The July 19, 1956 letter states that it was “enclosing
    a draft of the record of the discussions” between the United States and Denmark, and
    states that “[o]ur drafts have been compared with your attached draft and with the
    changes noted thereon the two copies are in complete agreement.” 7 (alteration added).
    Attached to the July 19, 1956 letter is a July 13, 1956 letter from Mr. Kristiansen to Mr.
    Jandrey which “[r]efer[s] to the discussions which have taken place from the 9th – 11th
    July between representatives of our two Governments on questions relating to the
    participation by Danish enterprises and labor in work on defense areas in Greenland” and
    states, “I hereby enclose a draft to an Agreed Record of the discussions.” (capitalization
    in original; alterations added). The July 13, 1956 letter further states, “[i]f you can agree
    to the wording of the draft I would propose that the draft should be regarded as an Agreed
    Record and that it formally constitutes the understanding arrived at in this matter between
    our two Governments.” (capitalization in original; alteration added). Enclosed with the July
    13, 1956 letter is an “Agreed Record of Meeting Held Between American and Danish
    Representatives July 9 and 10[, 1956] in Copenhagen on Contracts and Labor Used in
    Work on Defense Areas in Greenland,” (capitalization and emphasis in original; alteration
    added), which states, in relevant part, that “Construction, Operation and Maintenance
    contracts for works in the defense areas in Greenland will in future only be awarded to
    Danish and American enterprises.” Further, “[w]ith regard to the procedure to be followed
    for the awarding of contracts for work in Greenland,” the “Agreed Record” provides that
    that “if it was felt that the nature of the conditions was such as to place Danish enterprises
    at a handicap, consultation should take place between the contracting officers and
    contractors with a view of ensuring that proposals be submitted on an equal basis.”
    (alteration added). Moreover, the 1956 “Agreed Record” states that “Danish enterprises
    shall in every respect as in the past enjoy treatment no less favorable than that accorded
    to American concerns,” and that “Danish labor” would be employed “to the maximum
    extent possible.” (capitalization in original).
    According to protestor’s complaint, “[o]n August 29, 1962, the U.S. Department of
    the Air Force issued a letter entitled ‘Danish Participation in U.S. Defense Projects in
    7 The 1956 correspondence appears to document an “understanding” reached between
    the United States and Denmark, however, neither protestor nor defendant refers to the
    1956 correspondence in their briefs on the cross-motions for judgment on the
    Administrative Record.
    6
    Greenland,’ to which the Agency attached an ‘Aide Memoire’ from the State Department
    dated June 6, 1962.” (1962 Aide Memoire) (alteration added). The 1962 letter and the
    1962 Aide Memoire are attached to protestor’s complaint and are also included in the
    Administrative Record in the above captioned bid protest. The 1962 Aide Memoire refers
    “to the correspondence between the Ambassador of Denmark and the Assistant
    Secretary of the Air Force (Materiel) with regard to future Danish participation in work in
    United States defense projects in Greenland.” The 1962 letter and the 1962 Aide Memoire
    both refer to an agreement between the United States and Denmark in 1962, and the
    terms of the 1962 agreement appear in the 1962 Aide Memoire.8 The 1962 letter provides
    in relevant part:
    1.     The United States and Denmark agreed in 1951 t at [sic] Danish
    concerns would participate to the maximum extent possible consistent with
    other considerations in construction work in Greenland in connection with
    the Danish-American Agreement of April 27, 1951. The two Governments
    entered into a subsequent agreement in 1956 whereby the United States is
    committed to employ Danis [sic] nationals to the maximum extent possible
    and permit Danish enterprise to participate on an equal competitive basis
    with U.S. concerns in connection wit [sic] all USAF contract work in support
    of U.S. defense projects in Greenland.
    2.     Participation of Danish enterprise and nationals to be accomplished
    consistent with t e [sic] 1956 Agreement was defined more precisely by
    farther [sic] agreement between the United States and Denmark in June,
    1962. Details of the 1962 Agreement are proposed in the Department of
    State Aide Memoire, 6 June 1962 (Attachment 1), and accepted at the
    Government level as set fort [sic] in the approved minutes of the fifteenth
    meeting of the U.S.-Danis [sic] Committee on Greenland Projects
    (Attachment 2).[9] This letter directs AFLC and ADC implementation of the
    1962 Agreement.
    8 Although the 1962 letter and the 1962 Aide Memoire indicate that the United States and
    Denmark had reached an “agreement” in 1962, protestor claimed that the 1962 letter and
    the 1962 Aide Memoire were not “a treaty or international agreement” between the United
    States and Denmark, and defendant made no reference to a 1962 agreement. Moreover,
    neither party asserted that the 1962 letter or the 1962 Aide Memoire was relevant to the
    above captioned bid protest.
    9 The Committee concept appears in the 1962 documents and, therefore, predates the
    Permanent Committee established in a Memorandum of Understanding entered into on
    March 13, 1991 between the United States and the Kingdom of Denmark, discussed
    below. The Committee on Greenland Projects is the body which considered the 1962 Aide
    Memoire and at the meeting of which the Danish Government accepted the 1962 Aide
    Memoire. Whether the Committee on Greenland Projects was involved in the United
    States-Danish relationship during the gap in documents in the record before the court
    from 1962 to 1991 is unclear from the Administrative Record before the court.
    7
    3.     The 1962 Agreement may be viewed generally as being composed
    of three principal areas of participation: (a) that wherein U.S. firms and
    certain U.S. nationals only may participate; (b) that in w ic [sic] Danish
    concerns and labor only may be employed; and (c) that wherein both U.S.
    and Danish firms and personnel will be used. Specific detailed procedures
    to carry out eac [sic] of these areas are prescribed in Attac ments [sic] 3, 4,
    and 5, respectively.
    (alterations and footnote added). The 1962 letter further provides “[o]verall policies and
    basic functional responsibilities” in relevant part:
    a.     The 1962 Agreement is effective as of FY 1963.
    b.    Participation of U.S. and Danish firms and personnel will be in
    keeping with the 1956 Agreement, particularly with respect to base
    maintenance and repair work (Attachment 5), and as modified by the 1962
    Agreement in connection with radar installations (Attachment 3) and overall
    base support activities (Attachment 4).
    (alteration added).
    The 1962 Aide Memoire states, “with regard to future Danish participation in work
    in United States defense projects in Greenland,” that “[t]he subject has been thoroughly
    studied in the Department of the Air Force with the objective of ensuring as great a Danish
    participation in those projects possible.” (alteration added). The 1962 Aide Memoire
    proposes that Danish participation in United States defense projects in Greenland be
    evaluated according to “an overall approach,” rather than the then-existing procedures
    under which “a separate review for consistency with pertinent U.S.-Danish Governmental
    understandings is conducted for each contemplated U.S. defense project in Greenland.”
    The 1962 Aide Memoire states, in relevant part:
    Increasing the utilization of Danish contractors in the operation of our vital
    support bases at Thule and Sondrestrom is anticipated. It is estimated that
    Danish participation in this field will increase from less than $1 million at the
    end of Fiscal Year 1962 to approximately $9 million by the end of Fiscal
    Year 1965. Participation of Danish supplies in the areas of local purchase
    items and perishable subsistence will also be increased from practically no
    participation at the end of Fiscal Year 1962 to about a $3 million level by the
    end of Fiscal Year 1965.
    If agreeable to the Danish Government, it is contemplated that the total
    volume of such purchases for the Greenland Defense Area would be
    solicited each fiscal year from Danish sources by a purchasing activity
    located in Copenhagen.
    8
    (capitalization in original). The 1962 Aide Memoire further states, in relevant part:
    The Danish Government will also be interested in those areas wherein both
    Danish and U.S. suppliers compete on equal terms. Opportunities for
    increased Danish participation in competition with U.S. interests exist
    principally in base repair and maintenance work. It is possible that Danish
    participation could increase in this area since these requirements will be
    solicited, starting in Fiscal Year 1963, by the proposed procurement activity
    in Copenhagen.
    (capitalization in original). The 1962 Aide Memoire continues: “The net effect of the above
    procurement exclusions and inclusions, together with certain other miscellaneous
    contractual actions, is an unquestioned appreciable increase in total Danish participation
    even over the Fiscal Year 1962 level.” The 1962 Aide Memoire concludes with the
    statement that “[i]t is accordingly hoped that the foregoing will meet with approval of the
    Danish Government, and that discussions regarding pertinent implementing details can
    take place in Copenhagen as planned by the U.S.-Danish Committee on Greenland
    Projects.” (alteration added).
    Also attached to the 1962 letter are the “Minutes of the Meeting of the U.S.-Danish
    Committee on Greenland Projects,” (Minutes), which occurred between June 19 and 22,
    1962. According to the Minutes, “[t]he Danish member [of the Committee] stated his
    Government’s acceptance of the programs contained in the Aide-Memoire.” (alterations
    added). The Danish government’s acceptance of the 1962 Aide Memoire, as recorded in
    the Minutes, appears to be the basis for the 1962 letter’s assertion, quoted above, that
    the 1962 Aide Memoire was “accepted at the Government level” at the June 1962
    meeting.
    The Administrative Record in the above captioned bid protest does not document
    further diplomatic engagements between the United States and Denmark until 1991. 10
    The narrative in protestor’s complaint next addressed events in 1991 when “[t]he United
    States and the KoD executed an MOU [Memorandum of Understanding] which ‘[c]ame
    into force on 13 March 1991 by signature’ and which was ‘in implementation of the United
    States-Denmark Agreement Concerning the Defense of Greenland, dated April 27, 1951’
    and ‘related agreements,’” (alterations except “[c]ame” added), which was attached to
    protestor’s complaint and also included in the Administrative Record in the case currently
    before the court and was “enter[ed] into force on the date of signature by both Parties,”
    March 13, 1991. Memorandum of Understanding Between the Government of the
    Kingdom of Denmark (Including the Home Rule Government of Greenland) and the

    Greenland, Den.-U.S., art. XVI, Mar. 13, 1991, T.I.A.S. No. 12285 [hereinafter 1991
    10In fact, protestor’s complaint and the documents in the Administrative Record in this
    case also contain other chronological gaps in the relationship between the United States
    and the Kingdom of Denmark with respect to the United States’ military presence in
    Greenland, most notably between 1991 and 2004.

    Memorandum of Understanding] (alteration added). Protestor and defendant agreed that
    the 1991 Memorandum of Understanding constitutes a binding agreement between the
    United States and Denmark. The 1991 Memorandum of Understanding, in Article IV,
    “Construction and Contracting for Goods and Services,” (emphasis in original), provides:
    1. In accordance with existing agreements and practices, and with their
    respective laws and regulations, either Party may award contracts to
    commercial enterprises for goods and services, including construction
    projects, in Greenland and may procure directly from any US or
    Danish/Greenlandic source and may use its own military or civilian
    personnel to perform services or construction projects.
    2. When, in the future, the Government of the United States, for the support
    of US military facilities in Greenland, plans to establish long-haul
    telecommunication facilities and services in Greenland, the Government of
    the United States will consider sympathetically the availability of such
    facilities and services from Greenlandic sources and, to the extent
    compatible with its requirements and US law, will endeavour to utilize such
    Greenlandic facilities and services in a manner consistent with
    Danish/Greenlandic law.
    3. The United States will, when permissible under US law, offer competitive
    contracts to Greenlandic airline companies for US military air transportation
    requirements within Greenland. This undertaking is without prejudice to the
    right of the United States to use military aircraft within Greenland. Likewise,
    without prejudice to existing contracts, and when permissible by US law, the
    United States will offer competitive contracts to Greenlandic companies for
    US military sealift requirements within Greenland and between Greenland
    and Denmark. Furthermore, the United States will consider sympathetically
    other proposals from Danish/Greenlandic authorities concerning use of
    Greenlandic sources.
    
    Id.
     art. IV. (capitalization in original). The 1991 Memorandum of Understanding’s provision
    that “either Party may award contracts to commercial enterprises for goods and services,
    including construction projects, in Greenland and may procure directly from any US or
    Danish/Greenlandic source,” (capitalization in original), is an indication of an intention
    between the United States and Denmark increasingly to encourage procurements by the
    United States in Greenland from Danish/Greenlandic sources. This intention was later
    further agreed to by the United States and Denmark through “diplomatic channels” as
    also indicated in the 1991 Memorandum of Understanding, ultimately culminating in the
    eligibility criteria included in the prior 2014 Solicitation for the earlier contract and the
    eligibility criteria included in the Solicitation under review in this Opinion.
    The 1991 Memorandum of Understanding further provides, at Article VII,
    “Permanent Committee:”
    10
    1. In order to facilitate consultation and exchange of information on matters
    relating to the US military presence in Greenland, a United States-Danish
    Permanent Committee will be established on the date of entry into force of
    this MOU.
    2. The Permanent Committee shall be composed of representatives from
    the Government of the United States and representatives from the
    Government of Denmark and from the Home Rule Government of
    Greenland.
    3. The Permanent Committee shall consult and exchange information on all
    matters pertaining to the US military presence in Greenland in general and
    to the US military presence in Greenland in particular. The US
    representative will provide the Danish representative with timely information
    concerning any plans for significant changes to US military operations or
    facilities which could have an impact on the economy or environment in
    Greenland. Matters falling under the scope of the United States-Danish
    Committee on Greenland Projects will not be dealt with by the Permanent
    Committee.
    4. In the event that disagreement arises over a problem which cannot be
    resolved by the Permanent Committee, the issue shall be referred for
    resolution through diplomatic channels.
    (capitalization and emphasis in original). 
    Id.
     art. VII. The 1991 Memorandum of
    Understanding’s provision for consultation in the Permanent Committee or “through
    diplomatic channels” was established to build on the consultative framework established
    by the 1951 Agreement for the United States’ military presence and operation of defense
    areas in Greenland.
    According to protestor’s complaint, on August 6, 2004, “[t]he United States and the
    KoD executed an ‘AGREEMENT . . . TO AMEND AND SUPPLEMENT THE
    AGREEMENT OF 27 APRIL 1951.’” (2004 Agreement). (capitalization and ellipsis in
    original; alterations added). The 2004 Agreement was attached to protestor’s complaint
    and included in the Administrative Record in the above captioned bid protest. The 2004
    Agreement states that “Thule Air Base is the only defense area in Greenland. The
    provisions of Article II of the Defense Agreement[11] shall apply to the establishment of
    new defense areas.” Agreement Between the Government of the United States of
    America and the Government of the Kingdom of Denmark, Including the Home Rule
    Government of Greenland, to Amend and Supplement the Agreement of 27 April 1951
    Pursuant to the North Atlantic Treaty Between the Government of the United States of
    America and the Government of the Kingdom of Denmark Concerning the Defense of
    Greenland (Defense Agreement) Including Relevant Subsequent Agreements Related

    11 The 2004 Agreement refers to the 1951 Agreement as the “Defense Agreement”
    throughout.
    11
    protestor and defendant both considered the 2004 Agreement to constitute a binding
    agreement between the United States and Denmark. The 2004 Agreement in “Article 3:
    Local Cooperation,” at paragraph 1.c., provides:
    Consistent with the Defense Agreement, as amended herein, and the
    Memorandum of Understanding of March 13, 1991, and without prejudice
    to other relevant agreements and arrangements between the Parties, the
    Government of the United States will consult with and inform the
    Government of the Kingdom of Denmark, including the Home Rule
    Government of Greenland, prior to the implementation of any significant
    changes to United States military operations or facilities in Greenland.
    
    Id.
     art. 3, ¶ 1.c. (capitalization and emphasis in original). The 2004 Agreement, at article
    3, paragraph 2.b., provides:
    The Parties note and declare that they shall consult without undue delay
    regarding any question which one of the Parties may raise concerning
    matters pertaining to the U.S. military presence in Greenland and covered
    by the Defense Agreement and this agreement. To the extent that such
    matters cannot be resolved through local consultation, the Parties shall
    consult with each other either in the Permanent Committee or through
    diplomatic channels, as appropriate.
    
    Id.
     art. 3, ¶ 2.b. (capitalization in original). The 2004 Agreement provides that “the United
    States will consult and inform the Government of the Kingdom of Denmark” and that when
    “such matters cannot be resolved through local consultation, the Parties shall consult with
    each other in the Permanent Committee or through diplomatic channels,” building on the
    cooperative framework established by the prior 1951 Agreement and 1991 Memorandum
    of Understanding.
    According to protestor’s complaint, in 2008, the United States sent to the Kingdom
    of Denmark what protestor refers to as a “‘proposal’ regarding contracts related to
    commercial enterprises” in Greenland, “‘to replace Article IV, paragraph 1 of the 1991
    Memorandum of Understanding,’” which “the KoD ‘accept[ed]’” on January 27, 2009.
    (alteration in original). The “‘proposal’” referred to by protestor is included in the
    Administrative Record in the above captioned bid protest under the designation
    “Diplomatic Note 053 (July 16, 2008)” (Diplomatic Note No. 053). In Diplomatic Note No.
    053, the United States “refer[s] to recent discussions between representatives of the two
    governments regarding procedures for procurement of services for the U.S. Air Base at
    Thule, Greenland,” (alteration added), and the United States makes the following
    proposal:
    [T]he Embassy, on behalf of the Government of the United States, hereby
    proposes to replace Article IV, paragraph 1 of the 1991 Memorandum of
    Understanding in its entirety with the following:
    12
    “In accordance with their respective laws and regulations, either
    Party may award contracts to commercial enterprises for goods and
    services, including construction projects, in Greenland, and shall
    procure directly from Danish/Greenlandic sources. When
    procurement from such sources is not feasible, U.S. requirements
    may be satisfied by procurement from U.S. or other sources. Either
    Party may use its own military or civilian personnel to perform
    services or construction projects.”
    (alteration added). Diplomatic Note No. 053 further states that “[i]f the foregoing is
    acceptable to the Government of Denmark, the Embassy proposes that this note, together
    with the Ministry’s reply to that effect, shall constitute an agreement between the two
    governments, which shall enter into force on the date of the Ministry’s reply.” (alteration
    added).
    According to protestor’s complaint, the Danish Ministry of Foreign Affairs accepted
    the United States’ proposal in a note dated January 27, 2009, which protestor’s complaint
    referred to as the “2009 Amendment.”12 (2009 Agreement). The 2009 Agreement was
    attached to protestor’s complaint and included in the Administrative Record in the above
    captioned bid protest. As an amendment to the 1991 Memorandum of Understanding,
    protestor and defendant both agreed that the 2009 Agreement is a binding agreement
    between the United States and Denmark. The 2009 Agreement states that the Danish
    Ministry of Foreign Affairs is in “receipt of note no. 056 [sic] of July 16, 2008,” and quotes
    the United States’ proposal in full. (alteration added). Following the quoted language from
    the United States’ proposal, the 2009 Agreement states that “[t]he Ministry of Foreign
    Affairs has the honour to accept the proposal and declare that the note and this reply shall
    constitute an Agreement between our two countries which shall enter into force on the
    date of this note.” (alteration added). The 2009 Agreement’s provision that “either Party
    may award contracts to commercial enterprises for goods and services, including
    construction projects, in Greenland, and shall procure directly from Danish/Greenlandic
    sources,” is a clear instance of an intention and a requirement to limit eligibility for
    procurement by the United States in Greenland to only certain nationalities, individuals or
    companies after the 1991 Memorandum of Understanding. The 2009 Agreement is the
    most recent binding agreement between the United States and Denmark to set forth such
    a requirement as reflected in the record before the court in the above captioned bid
    protest. Moreover, the 2009 Agreement is the first appearance in the Administrative
    Record of the phrase “Danish/Greenlandic sources” as a limitation on offeror eligibility.
    12 Protestor’s briefs and defendant’s briefs refer to this document as the “2009
    amendment to the 1991 MOU.” As reflected below, regarding the document, Denmark
    states: “The Ministry of Foreign Affairs has the honour to accept the proposal and declare
    that the note and this reply shall constitute an Agreement between our two countries
    which shall enter into force on the date of this note.” The court generally refers to the
    document as the 2009 Agreement in this Opinion.
    13
    With the execution of the 2009 Agreement, the Administrative Record contains four
    international agreements between the United States and Denmark, which both protestor
    and defendant agree are binding agreements and which are relevant to the above
    captioned bid protest: The 1951 Agreement, as the foundational document of the United
    States’ military presence in Greenland, established the cooperative framework for the
    relationship between the United States and Denmark in Greenland; the 2004 Agreement,
    which amended the 1951 Agreement and further provided for diplomatic consultation to
    resolve issues related to the United States’ military presence in Greenland; the 1991
    Memorandum of Understanding, which also built on the framework of the 1951
    Agreement and established the Permanent Committee for consultation between United
    States and Danish officials, and set forth priorities on the nationalities for awarding
    contracts by the United States and Denmark with respect to the United States’ military
    operations in Greenland on the Thule Air Base; and the 2009 Agreement, which amended
    the 1991 Memorandum of Understanding, putting in place the restriction of awarding
    contracts to “Danish/Greenlandic sources” which is currently at issue in this protest.
    According to protestor’s complaint, in 2013 “the United States developed eligibility
    criteria with the Danish Ministry of Foreign Affairs” to be included in Request for Proposals
    No. FA2523-12-R0006, (the 2014 Solicitation), the predecessor solicitation which
    resulted in the earlier contract. The Danish Ministry of Foreign Affairs sent a letter to the
    United States Embassy in Copenhagen, dated December 9, 2013, which reflected an
    “agreement” that had been reached between American and Danish officials.13 The
    December 9, 2013 letter is attached to protestor’s complaint and is included in the
    Administrative Record in the above captioned bid protest. The December 9, 2013 letter
    to the United States Embassy in Copenhagen is signed by Danish State Secretary for
    Foreign Policy Kim Jørgensen. The December 9, 2013 letter, which preceded the 2014
    Solicitation for the earlier contract, provides in relevant part:
    I refer to the meeting held between the United States Embassy in
    Copenhagen and the Danish Ministry of Foreign Affairs on December 2 nd
    2013 and take this opportunity to confirm in writing the agreement reached
    regarding the Thule Air Base Maintenance Contract criteria.
    Firstly, as was decided the Ministry of Foreign Affairs will no longer issue
    clearances for companies eligible to participate in the procurement. It will
    hence be for the United States to assess whether a company qualifies as
    13 The 2013 diplomatic correspondence refers to an “agreement” between the United
    States and Denmark, however, protestor asserted that the 2013 diplomatic
    correspondence does not reflect a binding international agreement between the United
    States and Denmark, and defendant, adopting the position of protestor, did not argue that
    the 2013 diplomatic correspondence represents a binding agreement between the United
    States and Denmark.
    14
    Danish or Greenlandic based on predefined criteria.[14]
    Secondly, as described the Danish authorities consider that the purpose of
    restricting participation in the procurement to Danish/Greenlandic
    companies is to ensure Greenland and Greenlandic society greatest
    possible benefits from the agreement.
    It was in this spirit that it was suggested to narrow the criteria to only
    Greenlandic companies. However, the strong wish of the United States not
    to further limit the number of companies eligible to participate in the
    procurement is acknowledged. On this basis, the proposal from the United
    States that a company interested in participating in the procurement must
    provide the following information to prove that they qualify as a Danish or
    Greenlandic company is accepted:
    1 Submit corporation certificate (Selskabscertifikat m. oblat) verifying
    that the company is registered as a business in the Kingdom of
    Denmark. (Det Centrale Virksomhedsregister (CVR); Det
    Grønlandske Erhvervsregister (GER); Skráseting Føroya (Skrás Nr))
    14According to the 2015 GAO decision in the protest of the award of the earlier contract,
    not the protest of the Solicitation currently before the undersigned,
    [t]he parties [the United States and Denmark] concluded that Denmark
    could not be the country certifying that offerors were eligible Danish or
    Greenlandic sources, because doing so would trigger obligations under
    European Union procurement law. . . . [Danish Company Criteria
    Correspondence]. Additionally, allowing Greenland to determine the
    eligibility of each source was considered to create a conflict of interest
    because the incumbent contractor, Greenland Contractors, is partially
    owned by the government of Greenland.
    Per Aarsleff A/S, B-410782 et al., 
    2015 WL 1004252
    , at *2 (Comp. Gen. Feb. 18, 2015)
    (alterations added). The “incumbent contractor” identified by the 2015 GAO decision,
    Greenland Contractors I/S, appears to have a relationship to an offeror that moved to
    intervene in the above captioned bid protest, Greenland Contractors JV A/S, and the
    motion to intervene was opposed by protestor Vectrus. The nature of the relationship
    between Greenland Contractors I/S and Greenland Contractors JV A/S was not confirmed
    in any filing submitted to this court, and while protestor Vectrus originally raised a conflict
    of interest claim in its protest at the GAO in 2022, protestor made no such argument in
    the above captioned bid protest in this court. The court explained at the June 30, 2022
    hearing on the motion to intervene that Greenland Contractors JV A/S lacked standing to
    intervene in the bid protest currently before the undersigned because, due to the pre-
    award posture of the current bid protest, the prospective intervenor Greenland
    Contractors JV A/S could not demonstrate any interest which merited intervention.
    15
    NOTE: THE REGISTERED OFFICE OF THE ENTERPRISE SHALL
    BE IN THE KINGDOM OF DENMARK AND SHALL NOT BE
    REGISTERED AS A SUBSIDIARY OF FOREIGN COMPANY.
    2. Submit signed letter from an officer of a bank within the Kingdom
    of Denmark verifying that the company conducts business with that
    institution.
    NOTE: ELECTRONIC FUNDS TRANSFER OF INVOICE
    PAYMENTS WILL ONLY BE MADE TO A BANK IN THE KINGDOM
    OF DENMARK.
    I kindly ask you to confirm in writing the understanding as outlined above. I
    firmly believe a solution has been found which makes the assessment of
    what constitutes a company eligible to participate in the procurement more
    manageable, while at the same time maintaining the spirit of the
    agreements underlying the recent procurement procedure.
    (capitalization and emphasis in original; footnote added).
    According to protestor’s complaint, the United States Embassy responded in a
    letter dated December 13, 2013. The December 13, 2013 letter was attached to
    protestor’s complaint and included in the Administrative Record in the above captioned
    bid protest. The December 13, 2013 letter is signed by United States Ambassador J.
    Rufus Gifford and states:
    Thank you for your December 9 letter regarding the Thule Base
    Maintenance Contract and acceptance by Denmark and Greenland of our
    proposed criteria for companies wishing to participate in this U.S. Air Force
    procurement process. As you outlined in your letter, our use of these criteria
    will allow the United States to fulfill our obligations under our bilateral
    agreements related to Thule while streamlining the process for determining
    the eligibility of potential bidders. We appreciate your ministry’s
    collaboration on this issue.
    The offeror eligibility criteria agreed to by the United States and Denmark in the 2013
    diplomatic correspondence appear to be the earliest instance in the Administrative
    Record of the United States and Denmark agreeing on how to implement restrictions and
    interpreting the term “Danish/Greenlandic sources” from the 2009 Agreement to do so,
    as a result of the diplomatic consultative framework provided by the 1951 Agreement and
    expanded on by the 1991 Memorandum of Understanding, the 2004 Agreement, and the
    2009 Agreement.15
    15  Protestor tried to point out inconsistency on the part of defendant by quoting from a
    cross-motion for judgment on the Administrative Record filed by the United States in
    litigation concerning the 2014 Solicitation and incumbent contract for Base Maintenance
    Services at Thule Air Base. Per Aarsleff A/S v. United States, 
    121 Fed. Cl. 603
     (2015),
    rev’d, 
    829 F.3d 1303
     (Fed. Cir. 2016). The Per Aarsleff case, however, is not part of the
    16
    Protestor further argued that “[i]n 2014, the Agency [Air Force] determined that
    Exelis,” as Vectrus was then named, “was eligible to receive award of Contract No.
    FA2523-15-C-0001,” the Base Maintenance Contract currently being performed by
    protestor, pursuant to the earlier contract, at Thule Air Base, and “[t]he Agency awarded
    Exelis Contract No. FA2523-15-C-0001 on or about October 31, 2014,” the contract which
    preceded the current Solicitation. (alterations added). After the earlier contract was
    awarded to Exelis, three Danish corporations, Per Aarsleff A/S, Copenhagen Arctic A/S,
    and Greenland Contractors I/S, filed protests of the award of the earlier contract at the
    GAO. See Per Aarsleff A/S, B-410782 et al., 
    2015 WL 1004252
    , at *1. The GAO ultimately
    denied the protests leading subsequently to the Per Aarsleff cases before the United
    States Court of Federal Claims, Per Aarsleff A/S v. United States, 
    121 Fed. Cl. 603
    , and
    before the United States Court of Appeals for the Federal Circuit, Per Aarsleff A/S v.
    United States, 
    829 F.3d 1303
     (Fed. Cir. 2016). See Per Aarsleff A/S, B-410782 et al.,
    
    2015 WL 1004252
    , at *2. As relevant to the above captioned bid protest, the 2015 GAO
    decision denied the Per Aarsleff protests, stating “[t]he protesters argue that the award to
    Exelis Services was unreasonable because, they contend, the awardee is not a Danish
    litigation in the case currently under review other than as part of the part history of the
    United States’ military presence at Thule Air Base. The quote offered by protestor from
    defendant’s motion from the earlier Per Aarsleff litigation is:
    “On November 25, 2013, Denmark proposed criteria that would limit
    eligibility to Greenlandic companies, i.e., the enterprise must be registered
    in Greenland’s business registry (GER) under legislation applying to
    Greenland, the registered office of the enterprise must be in Greenland, the
    management of the contract must be performed in Greenland, and the
    enterprise must follow Greenland’s labor laws . . . In response to the United
    States’ concerns that this proposal limited competition to a greater degree
    than required by the relevant international agreements, an MFA [Ministry of
    Foreign Affairs] official represented that ‘any Danish company easily could
    meet these criteria by registering in Greenland and maintaining an office
    there.’ . . .
    Nevertheless, the United States rejected this proposal and instead
    proposed its own criteria for a ‘Danish/Greenlandic enterprise.’ . . . The MFA
    accepted the criteria proposed by the United States and memorialized them
    in a December 2013 letter to the United States ambassador, who responded
    favorably.”
    (emphasis and ellipses in original; alteration added) (quoting Def.’s Cross-Mot. J. Admin.
    R. at 8, Per Aarsleff A/S v. United States, 
    121 Fed. Cl. 603
     (Nos. 15-215C, 15-272C,15-
    330C)). The November 25, 2013 Danish proposal referred to in the above quotation from
    protestor’s complaint was not included in the Administrative Record currently before the

    Although the 2014 Solicitation is not included in the Administrative Record in the
    above captioned bid protest, the 2015 GAO decision in Per Aarsleff quotes the eligibility
    provisions for offerors included in the 2014 Solicitation:
    L–3. OFFEROR ELIGIBILITY
    Participation in this acquisition is limited to Danish/Greenlandic enterprises.
    Enterprises must possess a corporation certificate (Selskabscertifikat m.

    Id. at *4 (capitalization and emphasis in original; alteration added). The 2015 GAO

    16 The government in the 2015 Per Aarsleff bid protest before the United States Court of
    Federal Claims argued, as it did in the case currently before this court, that the Court of
    Federal Claims lacks jurisdiction to review the case pursuant to 
    28 U.S.C. § 1502
     (2018).
    See Per Aarsleff A/S v. United States, 
    121 Fed. Cl. at 621
     (protesting the 2014 Solicitation
    and subsequent award). The Judge of the Court of Federal Claims considered and
    rejected the government’s section 1502 argument, holding that the Court of Federal
    Claims had jurisdiction over protestors’ claims. See 
    id. at 622
    . Although the government
    and Exelis appealed the Court of Federal Claims’ decision in Per Aarsleff, the Court of
    Federal Claims’ decision with respect to the issue of jurisdiction was unchallenged on
    appeal and therefore was not addressed by the Federal Circuit. See generally Per Aarsleff

    Id.
     (capitalization, emphasis, and alterations in original). Based on the criteria in the 2014
    Solicitation, the three protestors in the earlier Per Aarsleff bid protests before the GAO,
    which would lead to the Per Aarsleff cases before the Court of Federal Claims and the
    Federal Circuit, argued before the GAO “that the Air Force could not have reasonably
    relied on the ‘registered as a foreign subsidiary’ provision of the RFP because, they
    contend, there was no way for a firm to register in the [Danish] CVR [Central Business
    Register] as a subsidiary of a foreign company,” and, therefore, “that the assessment as
    to whether an offeror is a ‘Danish/Greenlandic enterprise’ within the meaning of the RFP
    should turn on whether the prime contractor had Danish or Greenlandic ownership or
    control.” Id. at *8 (alterations added). The GAO concluded, however, “that the RFP’s
    eligibility analysis addressed whether the offeror was registered” in the Danish CVR “as
    a subsidiary of a foreign company,” and that “there are no other criteria in the RFP that
    explain how the agency would evaluate whether a firm was a Danish or Greenlandic
    enterprise.” Id. Accordingly, the GAO denied the protests filed by the three protestors and
    determined that the Air Force “reasonably found that Exelis Services was eligible for
    award under the terms of the solicitation.” Id. at *9.
    The three unsuccessful Per Aarsleff protestors at the GAO next filed bid protests
    of the 2014 Solicitation and subsequent award at the United States Court of Federal
    Claims, which were consolidated into one case, and the United States and Exelis
    defended the award of the earlier contract to Exelis. See Per Aarsleff A/S v. United States,
    
    121 Fed. Cl. at 607
    . Before the Court of Federal Claims, the Per Aarsleff protestors
    “argue[d] that the award to Exelis Services was improper because Exelis Services is a
    wholly owned Danish subsidiary of an American company, and therefore, it failed to meet
    an eligibility requirement set forth in the RFP that limited participation to Danish or
    Greenlandic businesses.” 
    Id.
     (alteration added).
    The Judge of the Court of Federal Claims in Per Aarsleff considered the same
    2014 Solicitation provisions relied upon by the GAO in the 2015 GAO decision, but
    reached a different conclusion on the basis that “it was not possible to register a company
    in Denmark as a subsidiary of a foreign company during the time of the procurement,”
    and, therefore, indicated that a reading of the 2014 Solicitation to exclude only those
    offerors registered in the Danish Central Business Register as subsidiaries of a foreign
    company “eviscerates any significant meaning from the eligibility criterion [in the 2014
    Solicitation] and renders the restriction illusory.” 
    Id. at 625
     (alteration added). The Judge
    19
    of the Court of Federal Claims in Per Aarsleff described the 1951 Agreement, the 1962
    Aide Memoire, the 1991 Memorandum of Understanding, and 2009 Agreement, as well
    as the formulation of the 2014 Solicitation’s eligibility criteria in diplomatic negotiations as
    reflected in the 2013 diplomatic correspondence. See 
    id. at 608-11
    . “Because it was not
    possible to register a company in Denmark as a subsidiary of a foreign company during
    the time of the procurement,” the Judge of the Court of Federal Claims in Per Aarsleff
    determined that “[s]ome recasting of the language in the Solicitation is necessary due to
    the defect in the eligibility criteria,” and for that purpose, “the court strongly prefers to
    excise the mistaken words” limiting eligibility to offerors “registered as a subsidiary of [a]
    foreign company,” and “preserving the remainder of the text and comporting with the
    evident intent of the procuring agency to implement the pertinent bilateral agreements.”
    
    Id. at 625
     (emphasis and alterations added). The Judge’s “excis[ion]” of “the mistaken
    words” rendered Exelis ineligible for award of the earlier Base Maintenance Contract, and
    the Judge of the Court of Federal Claims, therefore, held that “the agency’s decision to
    award Exelis Services the Thule Contract was arbitrary and capricious and not in accord
    with federal procurement law.” 
    Id.
     at 630 (citing 
    5 U.S.C. § 706
    (2)(A) (2012)).
    Attached to one of the protestors’ complaints in the Per Aarsleff bid protest of the
    earlier contract award was a Declaration, dated in the index of the Administrative Record
    in the above captioned protest as March 2, 2015, of Ambassador Jonas Bering Liisberg,
    Under-Secretary for Legal Affairs of the Danish Ministry of Foreign Affairs. The
    Declaration of Ambassador Liisberg also is attached to protestor’s complaint and included
    in the Administrative Record in the current protest before this court. The Declaration of
    Ambassador Liisberg provides, in relevant part, that the inclusion of the language “THE
    REGISTERED OFFICE OF THE ENTERPRISE SHALL BE IN THE KINGDOM OF
    DENMARK AND SHALL NOT BE REGISTERED AS A SUBSIDIARY OF FOREIGN
    COMPANY” in the 2014 Solicitation was proposed by the United States “to show the
    United States’ commitment to Greenland and the Greenlandic people benefitting from the
    U.S. presence at Thule.” Decl. of Jonas Bering Liisberg at 6, Per Aarsleff A/S v. United
    States, 
    121 Fed. Cl. 603
     (2015) (Nos. 15-215C, 15-272C, 15-330C) (capitalization in
    original). The Declaration of Ambassador Liisberg also states that “[i]n Denmark, a
    company cannot be listed in the public register, the Danish Business Register, as a
    ‘subsidiary’ or ‘a subsidiary of a foreign company,’” and that “[n]o such public registration
    category exists under Danish company law or in the Danish Business Registry. Nor is any
    other information on foreign ownership of a registered company recorded in the Danish
    Business Registry.” 
    Id.
     (alterations added). Rather, the Declaration of Ambassador
    Liisberg explained, “the definition of a ‘subsidiary’ relates to the ownership and/or the
    actual control exercised by the parent. Accordingly, a ‘subsidiary’ in Denmark is a
    company that is partly or completely owned by another company that has ‘decisive
    influence’ (in Danish: ‘bestemmende indflydelse’) over the subsidiary.” Id. at 7.17
    Moreover, according to several paragraphs of the Declaration of Ambassador Liisberg:
    17The phrase “‘decisive influence’ (in Danish: ‘bestemmende indflydelse’),” which from
    the record before the court seems to have first appeared in the Declaration of
    Ambassador Liisberg, appears identically in later documents as part of U.S.-Danish
    negotiations relating to Thule Base Maintenance Contract offeror eligibility, including the
    20
    31. “Decisive influence” means the power to control a subsidiary's financial
    and operational decisions. Decisive influence over a subsidiary is exerted if
    the parent company owns, directly or indirectly through a subsidiary, more
    than half of the voting rights in an enterprise, unless in special cases such
    ownership can be clearly demonstrated not to constitute a decisive
    influence.
    32. Where a parent holds half or less than half of the voting rights in an
    enterprise, decisive influence is exerted if the parent has (i) the power to
    exercise more than half of the voting rights according to an agreement with
    other investors, (ii) the power to control the financial and operational
    decisions of an enterprise under the Articles of Association or an
    agreement, (iii) the power to appoint or remove a majority of the members
    of the supreme management body, and this body exerts a decisive influence
    on the enterprise; or (iv) the power to exercise the de facto majority of votes
    at general meetings or at the meetings of an equivalent body, thus exerting
    the de facto decisive influence on the enterprise.
    33. The existence and effect of potential voting rights, including rights to
    subscribe for and purchase shares that are currently exercisable or
    convertible, must be taken into account in the assessment of whether a
    company exerts a decisive influence. Any voting rights attaching to the
    shares owned by the subsidiary itself or its subsidiaries must be disregarded
    in the calculation of voting rights in the subsidiary.
    Id. at 7-8.
    As noted above, Exelis and the United States appealed the Court of Federal
    Claims’ decision in the Per Aarsleff bid protest to the United States Court of Appeals for
    the Federal Circuit. See generally Per Aarsleff A/S v. United States, 
    829 F.3d 1303
    . On
    appeal, both Exelis and the United States argued that the Judge of the Court of Federal
    Claims had erred by invalidating the award to Exelis which was permitted by the “plain
    and unambiguous eligibility requirements” of the 2014 Solicitation. See 
    id. at 1308
    . The
    Federal Circuit noted that the restriction against awarding the earlier contract to offerors
    registered as a subsidiary of a foreign company came from the Air Force’s “mistaken”
    belief, based on an apparent mistranslation of Danish terms, that “subsidiary of a foreign
    company” was a registration option in the Danish Central Business Register. See 
    id. at 1306-07
    . The Federal Circuit determined that the 2014 Solicitation eligibility requirements
    were ambiguous. According to the Federal Circuit:
    proposed criteria by the United States that would ultimately accepted by Denmark, the
    diplomatic correspondence in which the United States and Denmark reached an
    agreement, and Solicitation No. FA2523-21-R-0001, the current Solicitation at issue in
    the bid protest currently before the court.
    21
    First, it could mean that bidders are ineligible if the registration in the CVR
    [Central Business Register] facially indicates that the business is a
    subsidiary of a foreign company. Under this interpretation, “registered as”
    indicates the registrant actively indicated, such as by checking a box in the
    CVR, that it was a subsidiary of a foreign company. Second, a company
    could be “registered as a subsidiary of a foreign company” if it is registered
    in the CVR and also a subsidiary of a foreign company, whether or not
    subsidiary status was affirmatively indicated at the time of registration and
    whether or not that status is apparent from inspecting the CVR after
    registration.
    
    Id. at 1310
     (emphasis in original; alteration added). The Federal Circuit held that a
    question posed by a potential offeror to the 2014 Solicitation, and the resulting answer
    from the Air Force, which were “incorporated into the final March 2014 solicitation,” had
    “resolved the ambiguity,” such that “the disputed eligibility provision, when properly
    interpreted, refers to whether the CVR facially indicates the company is a subsidiary of a
    foreign company.” 
    Id. at 1311
    . The Federal Circuit noted that “[c]ritically, there is nothing
    in the CVR that facially indicates Exelis is a subsidiary of a foreign company because, as
    the three unsuccessful bidders concede, it was impossible for the CVR to facially indicate
    such status.” 
    Id. at 1312
     (alteration added). Moreover, according to the Federal Circuit,
    “[w]hile it is true that any company could meet the eligibility criterion by simply registering
    in Denmark, the record indicates the Danish Ministry of Foreign Affairs was aware of the
    relative ease of corporate registration.” 
    Id.
     (alteration added).
    The Federal Circuit in Per Aarsleff further found that because “the ambiguity in the
    solicitation was patent, as reflected in the questions received by the Air Force and the two
    plausible interpretations indicated above,” by protesting only after award had been made
    to Exelis, two of the protestors had “waived any objection that the eligibility provision of
    the contract was defective.” 
    Id. at 1312, 1314
    . Moreover, the Federal Circuit denied the
    cross-appeals of two protestors arguing that the Air Force had “act[ed] arbitrarily in
    declining to evaluate, as a condition of eligibility, whether each bidder would during the
    course of performance comply with these Danish/Greenlandic sourcing requirements” for
    purchases and subcontracts under the earlier contract. 
    Id. at 1315
     (alteration added). The
    Federal Circuit, therefore, reversed the holding of the Court of Federal Claims and held
    that “Exelis met the disputed eligibility criterion,” without relying on the 1951 Agreement
    and the interpretations of the 1951 Agreement and subsequent agreements between the
    United States and Denmark, but acknowledging the ambiguous words of the 2014
    Solicitation and corporate registration requirements.18 See 
    id. at 1312
    .
    18 The Federal Circuit in Per Aarsleff briefly referred to the 1951 Agreement, 1991
    Memorandum of Understanding, and 2009 Agreement, and recounted the history of the
    2013 diplomatic correspondence, but the Federal Circuit did not rely on those documents
    when reversing the Judge of the Court of Federal Claims’ decision in Per Aarsleff and the
    Federal Circuit did not mention the 2004 Agreement. See Per Aarsleff A/S v. United
    States, 
    829 F.3d at 1306
    .
    22
    According to protestor’s complaint, following the Federal Circuit’s 2016 decision in
    Per Aarsleff, Exelis began performance on the earlier contract, although protestor’s
    complaint did not indicate the date on which Exelis commenced performance. Protestor’s
    complaint stated that, once the Federal Circuit allowed the contract to go forward, over
    the lifetime of the earlier contract, as of the date of the complaint, 181 modifications have
    been issued by the government, and the contracting activity has “obligated
    $259,726,464.77 in federal funds” for the earlier contract, “with an estimated total contract
    value of $405,811,630.33.”
    The Administrative Record in the above captioned bid protest includes a Standard
    Form 30 memorializing a modification to the earlier contract, identified as “Modification
    P00005,” executed on April 10, 2017 by Air Force Contracting Officer Patrick R. King and
    by Martha Hires on behalf of Vectrus. Modification P00005 states that “[t]he purpose of
    this Bilateral modification is to change the corporate name from Exelis Services A/S to
    Vectrus Services A/S.” (capitalization in original; alteration added). Modification P00005
    details the administrative changes associated with the change of name from Exelis to
    Vectrus, including an accompanying change of address, throughout the earlier contract
    documents, but Modification P00005 states that “[t]he total contract amount is unchanged
    at DKK [Danish Krone] 7,791,508,” and that “[t]he number of pages are unchanged at
    231.” (alterations added).19
    Protestor’s complaint in the current bid protest alleged that “since contract award
    in 2014, the Agency has consistently found Vectrus’s performance of the Thule BMC
    services exemplary.” The complaint quoted from a Declaration of Edward West, identified
    as “Vice President, Operational Excellence of Vectrus,” which was filed in support of
    protestor’s prior protest at the GAO of the current Solicitation and exclusion of Vectrus
    from the competition, which immediately preceded the above captioned bid protest, and
    stated that “‘Vectrus has provided performance to the client that has routinely been
    rated Very Good and Exceptional and never below Satisfactory.’” (capitalization and
    emphasis in original) (quoting Decl. of Edward West at 1, Vectrus Servs. A-S, B-420527
    et al., 
    2022 WL 1639491
     (Comp. Gen. May 18, 2022)). Protestor further alleged that in
    the Contracting Officer’s Statement of Facts in the protest brought by protestor at the
    GAO in 2022 regarding the current Solicitation and exclusion of Vectrus from the
    competition, “the Contracting Officer agreed with the characterization of Vectrus as being
    an incumbent contractor which has performed to the Agency’s satisfaction.”
    According to protestor’s current bid protest complaint filed in this court, protestor
    alleged that, following the 2014 award of the earlier contract to Exelis, the government of
    Denmark “expressed that it was displeased with the decision” to award the Base
    Maintenance Contract to Exelis. In its complaint, protestor alleged that the United States
    “eventually made a nonbinding political commitment to ensure that the follow-on contract
    19 Protestor’s complaint in the above captioned bid protest mainly referred to the
    incumbent contractor as “Vectrus,” without distinguishing when Exelis’ name was
    changed to Vectrus during performance of the earlier contract.
    23
    would be awarded to a company that was not American-owned.” Protestor alleged that
    as a result of this “political commitment” the United States “reinterpreted the 1991 MOU,
    as amended in 2009, more restrictively,” in order, according to protestor, to claim “that
    the international agreement no longer permits American-owned corporations to compete
    to provide the BMC service—even though none of the terms of the 1991 MOU, as
    amended in 2009, has changed.” (emphasis in original; alteration added).
    In its complaint in this court, protestor stated that “[i]n March 2015, the United
    States and the KoD released a ‘Joint Statement’ regarding the ‘Resolution of the Thule
    Base Maintenance Contract Acquisition Matter.’” (alteration added). The 2015 Joint
    Statement, attached to protestor’s complaint, is included in the Administrative Record in
    the above captioned bid protest. Although the 2015 Joint Statement document itself does
    not appear to be dated, the 2015 Joint Statement is dated “March 24, 2015” in the
    Administrative Record index certified for filing by Contracting Officer King. The 2015 Joint
    Statement is signed by both then-Acting Assistant Secretary of Defense for International
    Security Affairs Elissa Slotkin and Danish State Secretary for Foreign Policy Kim
    Jørgensen. The 2015 Joint Statement provides, in relevant part:
    For more than 60 years, the Kingdom of Denmark, including Greenland, and
    the United States have cooperated to provide for the defense of Europe and
    North America through mutually beneficial operations at Thule Air Base.
    Similarly, the partnership between the Kingdom of Denmark and the United
    States has endured through times of prosperity and times of challenge, and
    we remain close friends and Allies, working together on a wide range of
    critical global issues to achieve a better, more secure world for all. The
    United States has an interest in maintaining a presence at Thule Air Base,
    and in continuing the mutually beneficial relationship with the Kingdom of
    Denmark, including Greenland.
    Following the award of the Thule Air Base Maintenance Contract, the
    Kingdom of Denmark approached the United States to discuss concerns
    relating to the interpretation of international agreements between the two
    governments pertaining to the definition of a Danish/Greenlandic enterprise.
    On March 11, 2015, high-level consultations between the Kingdom of
    Denmark and the United States began in Washington, DC, regarding the
    international agreements applicable to the Thule Air Base Maintenance
    Contract solicitation. The representatives developed a framework intended
    to resolve, expeditiously and through diplomatic channels, all issues
    between the two governments relating to the interpretation of those
    international agreements in accordance with Article XIII(2) of the 1951
    Defense of Greenland Agreement (as amended), and are conducting
    further consultations to this end.
    The United States and the Kingdom of Denmark are endeavoring to address
    the concerns as follows:
    24
    • The United States and the Kingdom of Denmark have established an
    expert working group to develop a mutually acceptable definition of a
    Danish/Greenlandic enterprise.
    • The U.S. Air Force intends to conduct a new acquisition and issue a new
    request for proposals for the Thule Air Base Maintenance Contract once
    there is agreement between the United States and the Kingdom of Denmark
    regarding what constitutes a Danish/Greenlandic enterprise.
    • The U.S. Air Force intends then to competitively award a Thule Air Base
    Maintenance Contract. The United States and the Kingdom of Denmark will
    determine to what degree, if any, competition will be limited.
    The 2015 Joint Statement indicates that “high-level consultations” in “diplomatic
    channels” were used to resolve “all issues between the two governments relating to the
    interpretation of those international agreements in accordance with Article XIII(2) of the
    1951 Defense of Greenland Agreement,” consistent with the consultative framework
    established by the 1951 Agreement and expanded by the 1991 Memorandum of
    Understanding, the 2004 Agreement, and the 2009 Agreement.
    The Administrative Record in the above captioned bid protest also includes a
    “MEMORANDUM FOR AMBASSADOR H.E. LARS GERT LOSE,” signed by Robert S.
    Clarke, the “Deputy, Air Force Program Executive Officer for Combat and Mission
    Support,” dated October 11, 2016. (capitalization in original). In the October 11, 2016
    Memorandum, Mr. Clarke states, in relevant part:
    The U.S. Air Force (“Air Force”) remains committed to working with the
    Government of the Kingdom of Denmark (“Danish Government”) to develop
    acceptable eligibility criteria for the next Thule base maintenance contract
    acquisition.
    Although the current Thule base maintenance contract has been found by
    the U.S. courts to be legally valid, the Air Force has offered to conduct a re-
    competition of the Thule base maintenance contract prior to the expiration
    of its seven-year term, provided the United States and the Danish
    Government can agree on the definition of “Danish/Greenlandic sources.”
    As reflected in the March 2015 Joint Statement, the United States agreed
    to convene Working Group 1 to resolve the scope of the term
    “Danish/Greenlandic sources,” in accordance with our respective laws and
    regulations for the purpose of the follow-on acquisition of the Thule base
    maintenance contract. We agreed to suspend Working Group 1
    proceedings until the U.S. courts resolved the bid protests filed by three
    unsuccessful offerors.
    The October 11, 2016 Memorandum acknowledges that “[o]n June 23, 2016, the U.S.
    Court of Appeals for the Federal Circuit ruled in favor of the Air Force” and the earlier
    Base Maintenance Contract award, but that “following the award of the Thule base
    25
    maintenance contract, the Danish Government stated its objection to the eligibility criteria
    used in the [2014] Thule base maintenance solicitation.” (alterations added).
    The October 11, 2016 Memorandum further refers to an earlier Danish proposal,
    rejected by the Air Force, for eligibility criteria to be used for the re-procurement of the
    Thule Base Maintenance Contract. The Danish proposal had conditioned contractor
    eligibility on two requirements, unacceptable to the United States: “(1) the Government of
    Greenland must ‘own thirty-three percent (33%) of the contract company’; and (2) the
    exclusive purpose of the company is to perform Thule base operating services.” The
    October 11, 2016 Memorandum indicates that “[t]he Air Force must comply with U.S.
    competition laws in the Thule acquisition, and therefore can take no action to unduly
    restrict competition,” and that “the United States will not engage in further discussions
    concerning the proposal of the Danish Government and Government of Greenland during
    Working Group 1, or any proposal limiting the competition to government-owned
    contractors.” (alteration added). The October 11, 2016 Memorandum explains that “[i]n
    2013, the United States rejected a Danish Government proposal where only Greenlandic
    companies would be eligible to compete for the contract because it unnecessarily
    restricted competition,” but that the 2016 “subsequent proposal goes even further,
    containing eligibility criteria that are more restrictive than those rejected by the United
    States and the Danish Government previously.” (alteration added). The October 11, 2016
    Memorandum further explains that “[a]pplicable U.S. competition law has not changed
    since the Danish Government in 2013 accepted the U.S. position that the Thule
    competition cannot be restricted unnecessarily” and that “[i]t is not clear why a proposal
    more restrictive of competition than the one rejected in 2013 might be acceptable to the
    United States today.” (alterations added). The October 11, 2016 Memorandum
    concludes:
    The United States is committed to resolving the Thule contractor eligibility
    issue in a reasonable fashion, and stands ready to re-convene Working
    Group 1 within the next 30 days based on the understandings outlined in
    our response. To this end, attached to this response is the Air Force’s
    proposed eligibility criteria which satisfy our respective obligations under the
    relevant international agreements and also permit maximum competition
    among “Danish/Greenlandic sources.”
    Attached to the October 11, 2016 Memorandum are proposed eligibility criteria from the
    Air Force which would require offerors to the Thule Base Maintenance Contract to provide
    “[a] corporation certificate (Selskabscertifikat m. oblat) verifying that the company is
    registered as a business in the Kingdom of Denmark,” and “[a] signed letter from an officer
    of a bank within the Kingdom of Denmark verifying that the company conducts business
    with that institution.” (alterations added).
    Included in the Administrative Record in the above captioned bid protest also is a
    second memorandum similarly dated October 11, 2016, titled “MEMORANDUM FOR
    JAMES TOWNSEND, DASD(P) [Deputy Assistant Secretary of Defense (Policy)],”
    (capitalization in original; alteration added), written by Richard B. Clifford, Jr., Deputy
    26
    General Counsel, Acquisition, for the Department of the Air Force, with the subject “Legal
    Review of the Thule Proposal” (2016 Deputy General Counsel Review). The 2016 Deputy
    General Counsel Review sets forth the Air Force’s legal objections to the same Danish-
    proposed eligibility criteria rejected in the October 11, 2016 Memorandum. The 2016
    Deputy General Counsel Review reflects, in relevant part, the Air Force’s position that
    the [Danish] Proposal is inconsistent with U.S. acquisition law. As you are
    aware the 1991 “Memorandum of Understanding Concerning Use of
    Sondestrom [sic] Aviation Facility, Kulusuk Airfield, and Other Matters
    Related to United States Military Activities in Greenland”, as amended by a
    January 27, 2009 Exchange of Notes (hereinafter the “1991 MOU”),
    provides that “[i]n accordance with their respective laws and regulations,
    either Party may award contracts to commercial enterprises for goods and
    services . . . and shall procure directly from Danish/Greenlandic sources.”
    (Emphasis added). The 1991 MOU also states that “[w]hen procurement
    from such sources is not feasible, U.S. requirements may be satisfied by
    procurement from U.S. or other sources.” See 1653 U.N.T.S. 389 (quoting
    the Exchange of Notes).[20] The U.S. Competition in Contracting Act of
    1984, 
    10 U.S.C. § 2304
    , and its implementing regulations, require federal
    agencies to procure requirements through full and open competition to the
    maximum extent practicable, subject to certain exceptions. See 
    10 U.S.C. § 2304
    (c)(1)-(c)(7); Federal Acquisition Regulation (FAR) § 6.302. Even
    when these limited statutory exceptions apply, federal agencies are still
    required to promote competition to the maximum extent practicable given
    the circumstances. See e.g, [sic] FAR § 6.303(b)(6). Here, the Air Force has
    no statutory basis to require offerors--as a condition to proposal submission
    or contract award--to surrender a partial ownership interest to a third party,
    let alone a foreign government. Nor is the Air Force authorized by statute to
    dictate the business relationships of competing offerors.
    The 1991 MOU does not change this result. By its terms, the preference for
    Danish/Greenlandic sources expressed in the 1991 MOU must be read
    consistently with prevailing U.S. law, which prohibits the imposition of
    solicitation terms and conditions that are unduly restrictive of competition.
    See 
    10 U.S.C. § 2305
    (a)(1)(B) (solicitations shall include specifications
    which promote full and open competition and not include “restrictive
    provisions or conditions” unless “necessary to satisfy the needs of the
    agency or as authorized by law”); see also Total Health Res., B-403209,
    20The language quoted by the 2016 Deputy General Counsel Review is attributed by the
    2016 Deputy General Counsel Review to “1653 U.N.T.S. 389,” which is a citation to the
    1991 Memorandum of Understanding as it appears in the United Nations Treaty Series.
    The language quoted, however, is drawn from the 2009 Agreement, not from the original
    1991 Memorandum of Understanding. The parenthetical explanation “(quoting the
    Exchange of Notes)” appears to acknowledge that the language quoted comes from the
    2009 Agreement, which was effected by a proposal and acceptance set forth in diplomatic
    notes.
    27
    Oct. 4, 2010, 2010 CPD ¶ 226 at 3 (solicitation requirement for specialized
    experience on the part of the prime contractor was unduly restrictive of
    competition since the provision was not reasonably necessary to meet
    government needs). To be certain, the 1991 MOU requirement to “procure
    directly from Danish/Greenlandic sources” can be achieved through far less
    onerous and competitively restrictive means than foreign government
    ownership of single purpose offerors. Indeed, limiting the competition to
    companies owned in part by Greenland is inconsistent with the plain
    language of the 1991 MOU, which addresses “Danish/Greenlandic”
    sources, not just Greenlandic sources. Simply stated, any contractor
    eligibility criteria implementing the 1991 MOU must maximize the number
    of eligible offerors, and not unreasonably restrict or eliminate competition.
    Because the [Danish] Proposal would unnessarily [sic] restrict competition
    under the 1991 MOU, it cannot be considered feasible.
    (capitalization, emphasis, and third alteration in original; footnote added).
    Furthermore, the Administrative Record in the above captioned bid protest
    includes a “DIPLOMATIC NOTE,” (capitalization in original), dated July 13, 2017, by
    which the Danish government, through the Royal Danish Embassy in Washington, D.C.,
    submitted to the United States “an outline of an alternative proposal concerning the Thule
    Base Maintenance Contract.” (July 13, 2017 Diplomatic Note). The July 13, 2017
    Diplomatic Note states that “the Tax Authorities in Greenland have drafted the attached
    memo concerning the economic consequences for Greenland of the Exelis contract,” the
    iteration of the Thule Base Maintenance Contract Solicitation at issue in the above
    captioned bid protest.21 The July 13, 2017 Diplomatic Note sets forth the Danish
    government’s “alternative proposal:”
    1. The company which wins the tender and is awarded and concludes the
    Base Maintenance Contract shall accept that a company owned by the
    Greenland Government shall participate in the Base Maintenance
    Contract with a share of 33 per cent when the tendering process has
    been finalised [sic], see section 1.1 below.
    21  The Greenland Tax Authorities’ memorandum referred to in the July 13, 2017
    Diplomatic Note, which addresses the “economic consequences for Greenland of the
    Exelis contract,” appears in the Administrative Record as an attachment to the July 13,
    2017 Diplomatic Note. The memorandum in the Administrative Record, however, appears
    to be incomplete, consisting of only one page and ending mid-sentence. To the extent the
    document is in the record, the Greenland Tax Authorities’ memorandum, in relevant part,
    states “that Greenland received total revenue of DKK [Danish Krone] 237.8 million from
    Thule Airbase [sic] contract activities in 2015,” that “revenue is expected to be reduced to
    DKK 109.3 million in 2018 and further reduced to DKK 88.2 million in 2019,” and that
    “[t]he reduction in personal income tax comes from an estimated lower wage sum.
    Corporate tax is also expected to be affected by the lower bid made by Exelis” when
    competing for the earlier contract. (alterations added).
    28
    2. The Greenland Government company will participate in the Base
    Maintenance Contract on commercial terms. This means that the
    company shall carry its share of 33 per cent of any costs and benefits
    stemming from the Base Maintenance Contract, see section 1.1 below.
    3. The Greenland Government company’s participation in the Base
    Maintenance Contract shall not be established before the tendering
    process has been finalised [sic], see section 1.2 below.
    4. All real and genuine Danish/Greenlandic companies are qualified to
    participate in the tender for the Base Maintenance Contract, see section
    1.3 below.
    (capitalization in original; alteration added). The July 13, 2017 Diplomatic Note also
    includes an extended explanation of the Danish government’s proposal. Notable in the
    explanation in the Diplomatic Note is the Danish government’s indication that the contract
    awardee would be required to enter into a “chosen form of cooperation” with a company
    owned by the Greenlandic government, in which the Greenlandic government-owned
    company would have “an ownership share of 33 per cent” and “shall participate as a ‘silent
    partner’” during the performance of the contract. The explanation also states that under
    the Danish government’s alternative proposal:
    The Government of Greenland will during the tendering process not have
    an ownership interest in any potential offeror and no company owned by the
    Greenland Government will take part in the tendering process.
    All real and genuine Danish/Greenlandic companies (other than
    Government owned companies) may therefore take part in the tendering
    process, in full and open competition, and in accordance with the Defense
    Agreement.[22]
    (footnote added). The explanation further states that “[t]he company which wins the
    tender and is awarded the Base Maintenance Contract must be a real and genuine
    Danish/Greenlandic company. This is in accordance with the requirements and principles
    of the Defense Agreement,” and that “the objective of the Defense Agreement is to ensure
    that Greenland and the Greenlandic society enjoy the greatest possible benefits from the
    presence of US forces in Greenland. Terms to ensure this must also be included in the
    tendering terms.” (alteration added). The July 13, 2017 Diplomatic Note also includes the
    Danish government’s “Brief remarks on the question of free competition:”
    In the opinion of the Kingdom of Denmark, the proposed alternative model,
    as outlined above, implies an open and free competition between the
    entities participating in the tender.
    22The “Defense Agreement” referred to by the Danish government in the July 13, 2017
    Diplomatic Note appears to refer to the 1951 Agreement. The 2004 Agreement, quoted
    above, also refers to the 1951 Agreement as the “Defense Agreement.”
    29
    However, the Kingdom of Denmark has noted that, according to for example
    
    10 U.S. Code § 2304
    (c)(4), the US authorities are allowed to use
    procedures other than competitive procedures when the terms of an
    international agreement or a treaty between the United States and a foreign
    government have the effect of requiring the use of procedures other than
    competitive procedures.
    If the US authorities disagree with the Kingdom of Denmark in relation to
    the matters stated above, it is thus the opinion of the Kingdom of Denmark
    that the consequence will be that the Defense Agreement requires the use
    of such other procedures meaning that the US authorities are allowed to
    use such other procedures.
    (emphasis in original).
    The Administrative Record in the above captioned bid protest contains another
    diplomatic note, issued August 17, 2017 by the Royal Danish Embassy in Washington,
    D.C., requesting to schedule discussions with the United States government later that
    year regarding the Thule Base Maintenance Contract. (August 17, 2017 Diplomatic Note).
    The August 17, 2017 Diplomatic Note also encloses a memorandum in response to the
    Air Force’s expressed concerns regarding involving the Greenlandic government during
    discussions of the Thule Base Maintenance Contract offeror eligibility requirements, on
    the grounds that the Greenlandic government would have an ownership interest in one of
    the potential offerors, Greenland Contractors. The Danish government states in the
    memorandum its belief that “[g]iven the extensive nature of Greenland’s autonomy, any
    negotiations over Thule must include the elected Greenland Government,” and that “US
    procurement law” does not “appl[y] to a negotiation concerning an international
    agreement.” (alterations added). The Danish government further states in the
    memorandum:
    While in the end, there will ultimately be a new contract solicitation with new
    eligibility criteria, this will be the result of a two-step process. First, the
    Kingdom of Denmark and the United States will clarify the meaning of 1991
    MOU in an agreement between sovereign governments establishing what
    defines a real and genuine Danish/Greenlandic company. Second,
    consistent with this international agreement, the US Air Force will draft and
    then issue a new solicitation that complies with the accepted agreement.
    While the second step involves the acquisition process that is subject to the
    FAR, the first step does not.
    In the first step, the governments of the US, Denmark, and Greenland will
    discuss the general and fundamental rules and agreements governing the
    operation of Thule Air Base, as memorialized in the Memorandum of
    Understanding of 1991 between the United States and the Kingdom of
    Denmark. The Thule MOU is not the first time a host country has insisted
    on a domestic preference for the supply of goods and services to a US
    military base outside the borders of the United States. The US Government
    30
    has negotiated several other international agreements giving priority
    treatment to the nationals of other countries providing base rights.
    (footnote omitted).
    The diplomatic note from the Royal Danish Embassy in Washington, D.C., dated
    September 1, 2017, expressing the Danish government’s “deepest concern” at the
    “awarding of the sea lift contract on the Thule Air base to the American company, Schuyler
    Line Navigation Company LLC,” and stating the “need to consider how we in cooperation
    can ensure that the sea lift contract will be awarded to a Greenland company,” is included
    in the Administrative Record in this protest. The September 1, 2017 Diplomatic Note
    further “draw[s] attention to the upcoming renewal of the air transport contract on the
    Thule Air Base,” and “respectfully urges the Department of Defense to award the future
    air lift contract to a Greenland company if its bid for the contract is competitive.” (alteration
    added).
    Subsequently, the Deputy Assistant Secretary of Defense sent a January 3, 2018
    letter to Danish Ambassador Lars Gert Lose, a copy of which is included in the
    Administrative Record, which responds to the Danish government’s July 13, 2017
    Diplomatic Note, as well as referring to discussions which occurred in September 2017,
    but it does not appear to reference the August 17, 2017 Diplomatic Note. The January 3,
    2018 letter rejects the Danish government’s “alternative proposal” from the July 13, 2017
    Diplomatic Note, stating:
    We are unable to accept your proposal under our international agreements
    and U.S. contracting laws, regulations, and policy. The type of arrangement
    in your proposal would require an exemption for Department of Defense
    entities contracting in Greenland from free and open competition among
    “Danish/Greenlandic sources” because it would further limit part of the
    contract to just one entity without competition. At a minimum, your proposal
    would require a new international agreement or a substantial amendment
    to current agreement. Entering into negotiations concerning a new
    agreement or an amendment to the current bilateral agreement would
    require the involvement and approval of the Department of State and any a
    new [sic] agreement or an amendment to the current bilateral agreement
    would be subject to current U.S. Government-wide policies.
    We recommend working through the previously-agreed-upon workgroup
    structure and continuing to have open and candid conversations to facilitate
    resolution of the Thule Air Base Maintenance Contract concerns. Through
    this structure, we will be able to provide immediate feedback to one another
    and chart a mutually-beneficial way forward.
    (alteration added).
    The Administrative Record in the above captioned bid protest also includes a
    “Non-paper regarding the definition of a Danish/Greenlandic enterprise,” prepared
    31
    by the Danish government and dated November 23, 2019. (capitalization and emphasis
    in original). The “non-paper” provides that “[i]n order to advance the work of Working
    Group 1 on a mutually agreeable definition of Danish/Greenlandic company, the Kingdom
    of Denmark invites the US to consider whether a new definition may include the following
    elements,” which is followed by a detailed list of proposals, including “[e]xhaustive and
    detailed definitions regarding certain terms, including Greenlandic company, Greenlandic
    owned, Greenlandic party, Greenlandic person, Greenlandic worker, Danish company,
    Danish owned, Danish party, Danish person and U.S. law;” the requirement that “[a]n
    offeror shall be, and shall remain in the entire contract period of an awarded contract, a
    Greenlandic company which is either Greenlandic owned or Danish owned, both directly
    and indirectly, and which is liable to pay direct and indirect taxes to the Greenland
    Government;” requiring “an objective legal opinion from a Greenlandic or Danish law firm
    to certify that the offeror company fulfils the set requirements;” “conduct[ing] new
    procurement processes until the contract is awarded to an offeror which fulfills the set
    requirements;” requiring the use of “Greenlandic workers” and “Greenlandic companies
    which are Greenlandic owned as suppliers to supply the goods and services,” “[t]o the
    maximum extent possible;” the inclusion of “a mandatory right to participate” for “[a]
    company owned by the Government of Greenland,” not to “include any ownership of the
    company which has been awarded the contract,” but under which “the company owned
    by the Government of Greenland shall pay a share of 33 per cent of the capital
    investments and costs and earn a share 33 per cent of the income under the contract;”
    and the provision that the “requirements which an offeror company shall fulfil (as stated
    above), shall have precedence and prevail over any U.S. law.” (alterations added).
    Attached to protestor’s complaint and included in the Administrative Record
    currently before the court is a United States Department of State document referred to in
    the Administrative Record index as the “Embassy Copenhagen Démarche (May 26,
    2020).” (2020 Démarche). The 2020 Démarche appears to provide background
    information and “talking points” for use by United States Embassy officials in discussion
    with Danish Ministry of Foreign Affairs officials regarding offeror eligibility for the Thule
    Base Maintenance Contract. The 2020 Démarche states its “Subject” as “Presenting the
    Definition of a Danish or Greenlandic Source,” and provides, in relevant part:
    The 2014 award of the Thule Air Base maintenance contract to a Danish
    subsidiary of a U.S. company remains an obstacle to strengthening the
    U.S.-Greenland partnership. The Government of Greenland (GoG) has
    repeatedly emphasized the contract has “symbolic” and economic
    importance to the people of Greenland. The current maintenance contract
    may be extended using one-year options until 2024 and the Department of
    Defense would have to re-compete it no later than 2023. The U.S. Air Force
    indicated its willingness to begin the process needed to recompete the
    contract as early as 2021 if the United States, Denmark, and Greenland
    could clarify the definition of a “Danish/Greenlandic source” to the
    satisfaction of the Kingdom of Denmark and the United States. In December
    2019, the GoG outlined its priorities for the next contract solicitation via a
    non-paper from the Danish Ministry of Foreign Affairs. These included: a
    32
    requirement for a company to be Greenlandic or Danish owned (both
    directly and indirectly); liable to pay direct and indirect taxes to the GoG;
    that local labor be employed to the maximum extent possible; and that the
    GoG have a mandatory 33 per cent share of the awarded contract.
    (capitalization in original). The 2020 Démarche further provides:
    Washington remains committed to resolving the definitional issue in a
    manner consistent with U.S. law and regulation while at the same time
    satisfying the Kingdom of Denmark, including Greenland. The Washington
    interagency has drafted a proposal that provides the best starting point for
    negotiations with our Danish and Greenlandic partners. In order to arrive at
    a legally workable solution by October, 2020 to satisfy the U.S. Air Force
    timeline for re-solicitation, the negotiation process with Denmark and
    Greenland must begin now. Embassy Copenhagen should present this
    proposal on May 29 with a request for immediate follow-on meetings,
    convened by Embassy Copenhagen and include appropriate
    representatives from the Kingdom of Denmark, EUR, L, OSD [Office of the
    Secretary of Defense], and U.S. Air Force contractual and legal specialists.
    Simultaneously with the delivery of these points to relevant Kingdom of
    Denmark authorities, OSD will deliver a copy of the attached non-paper to
    the Danish Defense Counselor and the head of the Greenlandic
    representation in Washington. During the teleconference that follows
    delivery, we should agree to a follow-on meeting, within one week, to
    discuss initial Danish and Greenlandic reactions and next steps.
    (capitalization in original; alteration added). The 2020 Démarche also sets forth the
    following proposal from the United States for eligibility criteria for the Thule Base
    Maintenance Contract:
    •   An offeror shall be registered as a Danish/Greenlandic company in the
    Central Business Register; shall be more than 50 percent equity owned
    by Danish or Greenlandic individuals, corporations, or entities; and a
    non-Danish or Greenlandic individual or company shall not have a
    decisive influence over the offeror.
    •   As part of the offer, the offeror must also present a letter from a Danish
    or Greenlandic bank certifying banking service.
    Accompanying the above-quoted proposal, the 2020 Démarche lists a number of “talking
    points” for the United States Embassy officials, including the “belie[f]” that the United
    States’ proposal “directly addresses the core issue related to the selection of a bidder and
    this will be the starting point of a mutually beneficial collaboration to a final resolution.”
    (alteration added).
    Attached to the 2020 Démarche is a document which is referred to in the
    Administrative Record index as “Proposed Criteria for the Thule Base Maintenance
    33
    Contract (May 7, 2020).” The document states that it contains “Proposed Criteria for
    The Thule Base Maintenance Contract,” (capitalization and emphasis in original), but
    the document itself does not include a date. The document appears to elaborate on the
    proposal set forth in the 2020 Démarche:
    The U.S. contracting officer would use the criteria below to meet the
    requirement of “Danish/Greenlandic source”:
    1. As part of its offer, an offeror must certify that throughout the term
    of the contract:
    a. it shall be registered as a Danish or Greenlandic company in
    the Danish Central Business Register;
    b. more than 50 percent of the offeror’s equity shall be owned by
    Danish or Greenlandic individuals, corporations, or entities;
    and
    c. a non-Danish or Greenlandic individual, company, shall not
    have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror.
    2. As part of its offer, an offeror must present a letter from a Danish
    or Greenlandic bank certifying banking service.
    (footnote omitted).23 The May 7, 2020 proposed criteria are the earliest-dated occurrence
    of the fifty-percent Danish or Greenlandic ownership requirement which would eventually
    be included in the Solicitation currently at issue.
    According to protestor’s complaint, “on October 27, 2020, the United States
    Embassy in Copenhagen, Denmark, issued ‘Diplomatic Note’ ‘No. 127’ which adopted
    almost verbatim the United States’ proposal from the May 26, 2020 Démarche”
    (Diplomatic Note No. 127). Diplomatic Note No. 127 was attached to protestor’s complaint
    and included in the Administrative Record in the above captioned bid protest. Diplomatic
    Note No. 127 provides, in relevant part:
    In order to fulfill the commitments made in the Thule Air Base Joint
    Statement, and to ensure that the Thule Base Maintenance Contract is
    awarded to a “Danish/Greenlandic source” as required by the Memorandum
    of Understanding between the United States of America and the
    Government of the Kingdom of Denmark (including the Home Rule
    Government of Greenland) Concerning Use of Sondrestrom Aviation
    Facility, Kulusuk Airfield, and Other Matters Related to United States
    Military Activities in Greenland, signed at Copenhagen March 13, 1991, as
    23 The “May 7, 2020 Proposed Criteria” document includes a footnote on the phrase
    “decisive influence,” which footnote contains a multiple-paragraph quotation from the
    Declaration of Ambassador Liisberg, discussed above, addressing the meaning of
    “decisive influence” under Danish law.
    34
    amended July 16, 2008, and January 27, 2009, the U.S. Department of
    Defense will apply the following eligibility criteria:
    1. As part of its offer, an offeror must certify that at the time of offer
    submission and throughout the term of the contract:
    a. it is, and shall remain, registered as a Danish or Greenlandic
    company in the Danish Central Business Register;
    b. more than 50 percent of the offeror's equity, defined as the entire
    capital of the company, is, and shall continue to be, owned by
    Danish and/or Greenlandic individuals or legal entities; and
    c. a non-Danish or non-Greenlandic individual or legal entity does
    not, and shall not, have a “decisive influence” (in Danish:
    “bestemmende indflydelse”) over the offeror.
    2. As part of its offer, an offeror must present a letter from a Danish or
    Greenlandic bank certifying banking service.
    Additionally, in order to implement the Thule Base Maintenance Contract in
    a manner that accords maximum mutual benefit, the U.S. Department of
    Defense will award the Thule Base Maintenance Contract to the source
    providing the best overall value, rather than as a Lowest Price Technically
    Acceptable source selection, thus fully accounting for the benefits of local
    expertise and knowledge and other non-monetary benefits in the
    competition.
    As part of the best-value analysis, the process for the forthcoming
    competition will include a non-cost factor competitive enhancement for an
    offeror that is registered as a Greenlandic source as well as the contractor’s
    physical presence in Greenland, including management presence.
    (capitalization in original; footnote omitted).24 Diplomatic Note No. 127 further states that
    the Base Maintenance Contract to be awarded
    24  Diplomatic Note No. 127 includes a footnote on item 1.c. of its proposed eligibility
    criteria which states: “Discussed in the Declaration of March 19, 2015, [sic] submitted by
    the Kingdom of Denmark to the U.S. Court of Federal Claims in Nos. 1:15-cv-00215,
    00272 and 00330- CFL.” (emphasis in original; alteration added). The “Declaration”
    referred to in the footnote to Diplomatic Note No. 127 appears to be the Declaration of
    Ambassador Liisberg, discussed above, which appears to be the source of the “decisive
    influence” language which appears in the proposed criteria of Diplomatic Note No. 127.
    Moreover, as noted above, although Diplomatic Note No. 127 states that the Liisberg
    Declaration is dated “March 19, 2015,” (emphasis in original), the index of the
    Administrative Record in the current bid protest states that the Liisberg Declaration is
    dated March 2, 2015, as do the decisions of the United States Court of Appeals for the
    Federal Circuit and the United States Court of Federal Claims in the Per Aarsleff litigation.
    35
    will include a combination of requirements, incentives, and/or evaluation
    factors to fulfill the defense mission, including positive and inclusive
    relations with the people and business community of Greenland, in the spirit
    of the Agreement Between the Government of the United States of America
    and the Government of the Kingdom of Denmark, Including the Home Rule
    Government of Greenland,
    and Diplomatic Note No. 127 lists examples of such “requirements, incentives, and/or
    evaluation factors,” including:
    1. the contractor’s physical presence in Greenland, including management
    presence, necessary to interface effectively with the Government of
    Greenland, the business community of Greenland, and other entities in
    order to meet the contract targets, including the labor targets;
    2. target metrics for employing Greenlandic residents;
    3. targets for measurable increases in Greenlandic workers’ participation
    over the contract period;
    4. contractor outreach efforts to employ Greenlandic workers to the
    greatest extent possible, including for placement of apprentices and
    trainees and for older adult placement.
    Diplomatic Note No. 127, in its conclusion, states:
    If this proposal is acceptable to the Ministry of Foreign Affairs of the
    Kingdom of Denmark together with the Ministry of Foreign Affairs and
    Energy of the Government of Greenland, this note and attachment, together
    with your affirmative reply, will constitute an understanding between our
    Governments, recognizing that this understanding does not constitute a
    treaty under Article 2(1)(a) of the Vienna Convention on the Law of Treaties.
    Attached to protestor’s complaint and included in the Administrative Record in the
    above captioned bid protest is a response to Diplomatic Note No. 127, labeled a
    “NoteVerbale,” (emphasis in original), dated October 27, 2020, from the Danish Ministry
    of Foreign Affairs to the United States Embassy in Copenhagen. The “NoteVerbale”
    states that “[t]he Ministry of Foreign Affairs of the Kingdom of Denmark together with the
    Ministry of Foreign Affairs and Energy of the Government of Greenland” has received
    Diplomatic Note No. 127 and “accept[s] the proposal therein in order to ensure Greenland
    and the Greenlandic society the greatest possible benefits from the U.S. defense
    presence at Pituffik (Thule Air Base).” (alterations added). Both protestor and defendant
    agreed that Diplomatic Note No. 127, while having been “accept[ed]” by the Danish
    government, does not constitute a binding international agreement between the United
    States and Denmark, nor does it constitute an amendment to any binding agreement
    See Per Aarsleff A/S v. United States, 
    829 F.3d at
    1310 n.3; Per Aarsleff A/S v. United
    States, 
    121 Fed. Cl. at 611
    .
    36
    between the United States and Denmark. (alteration added). Diplomatic Note No. 127
    and the Danish government’s reply on October 27, 2020, however, represent the United
    States and Denmark’s continued engagement in the cooperative and interpretive
    framework established by the 1951 Agreement and expanded on by the 1991
    Memorandum of Understanding and the 2004 Agreement. Moreover, Diplomatic Note No.
    127 is a demonstration of the United States and Denmark’s use of diplomatic consultation
    to interpret the term “Danish/Greenlandic sources” from the 2009 Agreement in the
    course of establishing eligibility criteria to be used for contracting at Thule Air Base and
    to ensure the United States’ military presence at the base and the continued diplomatic
    relationship between the United States and Denmark.
    The Administrative Record in the above captioned bid protest also includes a
    document, titled “Common Plan for U.S.-Greenland Cooperation in Support of Our
    Understanding for Pituffik (Thule Air Base),” and signed by the Ambassador of the
    United States to the Kingdom of Denmark and the Premier of Greenland. (capitalization
    and emphasis in original). While the Common Plan is listed in the Administrative Record
    index as being dated October 28, 2020, the day after Diplomatic Note No. 127 was sent
    and accepted, no date appears on the Common Plan document included in the
    Administrative Record. The Common Plan provides, in relevant part:
    This Common Plan for U.S.-Greenland Cooperation (“Common Plan”) is
    intended to contribute to strengthening the partnership and the prosperous
    relationship between the United States of America and Greenland by
    building on the close relationship reflected in the exchange of diplomatic
    notes dated October 27, 2020, regarding the Pituffik (Thule Air Base) base
    contract and related matters. The United States is committed to working
    with the Government of Greenland to realize this Common Plan through
    mutual efforts, exchange of good practices, and close coordination. The
    Common Plan’s objectives are intended to be met through diplomatic
    engagement and agency and ministry cooperation.
    (capitalization in original).
    The Administrative Record in the above captioned bid protest further includes a
    document titled “Statement on Improved Cooperation in Greenland – Including at
    Pituffik (Thule Air Base),” (Statement on Improved Cooperation) which, like the
    Common Plan, is also dated October 28, 2020. (capitalization and emphasis in original).
    Although unsigned, the Statement on Improved Cooperation indicates that it is a “Joint
    Declaration” by “representatives of the Government of the United States of America and
    the Government of the Kingdom of Denmark together with the Government of Greenland.”
    (capitalization in original). The Statement on Improved Cooperation provides, in relevant
    part:
    The United States of America, Denmark, and Greenland share a long
    history of cooperation based on a deep respect for each other and for
    democracy, human rights, and the rule of law. We recognize that our future
    37
    security and prosperity are linked to strong trans-Atlantic cooperation.
    Pituffik (Thule Air Base) in Northwest Greenland is central to securing this
    fundamental cooperation now and into the future. In view of Pituffik’s and
    Greenland’s key role in Greenlandic, U.S., and transatlantic security, and
    based on our close dialogue concerning the base maintenance contract at
    Pituffik, we set out together to increase the benefits to the people of
    Greenland, through the understanding set forth in the exchange of
    diplomatic notes, including attachment,[25] dated October 27, 2020, and the
    Common Plan for U.S.-Greenland Cooperation signed October 28, 2020.
    We are committed to strengthening and deepening our cooperation in all
    areas, including politically, economically, and on peace and security.
    Accordingly, we acknowledge the relevance of a full-fledged strategic
    partnership.
    We are committed to advancing and monitoring the progress of the
    initiatives specified in the paragraphs above within the framework of the
    Permanent Committee, established in 1991, and the Joint Committee,
    established in 2004, as applicable.

    Solicitation No. FA2523-21-R-0001 and the Thule Base Maintenance Contract
    The Administrative Record in the above captioned bid protest includes a “MARKET
    RESEARCH REPORT FOR THULE BASE MAINTENANCE CONTRACT (BMC),” which
    is listed in the Administrative Record index as dated “June 23, 2021.”26 The Market
    Research Report provides information about the “Unusual Conditions or Constraints”
    of the Base Maintenance Contract at Thule Air Base, including, under the heading “b.
    International Relations:”
    Greenland is a self-governing entity of the Kingdom of Denmark. Exceptions
    to self-governance include foreign policy and defense. Current agreements
    allow the USG [United States Government] rent-free use of the land on
    25The Statement on Improved Cooperation, as it appears in the Administrative Record in
    the protest currently before the court, includes no such attachment, nor have the parties
    provided one. The description of the attachment as part of an “exchange of diplomatic
    notes” which is “dated October 27, 2020,” suggests that the attachment referred to by the
    Statement on Improved Cooperation was Diplomatic Note No. 127.
    26The Market Research Report, however, includes on its cover page the date “April
    2021.” (capitalization and emphasis in original). The signature page of the Market
    Research Report, however, which is included twice in the Administrative Record, once as
    part of the Market Research Report document, signed by Contracting Officer Patrick R.

    Specialist Jesper Nielsen, is dated June 23, 2021 both times it appears.

    which the Thule Defense Area is located. [redacted]. Contractual and
    regulatory requirements are often clouded by international politics of the
    participating counties. Examples include questions regarding which safety,
    environmental, fire protection, and food handling regulations apply to the
    Thule BMC contractor, i.e., should the standard mirror those set at other
    DAF installations or should it be the standard most applicable to the
    Greenlandic environment and Danish commercial standards. The base
    commander must balance the needs of many groups, as commanding
    Thule is like running a small, culturally diverse city. In addition to considering
    the needs of the military (US and Canadian) and contractor (US, Danish,
    and Greenlandic) communities, the commander must interface with the on-
    site Danish Liaison Officer (DLO), the Danish police inspector (DPI), and
    the Greenlandic City Council.
    (capitalization and emphasis in original; alteration added). The Market Research Report
    further provides, under the heading “c. International Agreement,” certain details about
    only two of the relevant international agreements:
    An International Agreement, dated 27 April 1951, exists between the
    Kingdom of Denmark and the United States of America. In accordance with
    a 16 July 2008 Diplomatic Note [Diplomatic Note No. 053][27] response to
    that agreement, it was clarified that all goods and services, including
    construction projects, shall be procured directly from Danish/Greenlandic
    sources. “When procurement from such sources is not feasible, US
    requirements may be satisfied by procurement from US or other sources.
    Either party may use its own military or civilian personnel to perform
    services or construction projects.” Contracts involving National Security are
    an exception to this policy. The agreement does not limit non-Danish or non-
    Greenlandic subcontracts or joint ventures. Market research (described
    below) indicates that capable Danish/Greenlandic sources exist for the
    subject requirement; therefore, this acquisition will be limited to
    Danish/Greenlandic sources using other than full and open procedures in
    accordance with Federal Acquisition Regulation (FAR) 6.302-4 --
    International Agreement. Other terms related to the International
    Agreement or Status of Forces Agreement (SOFA) are that only Danish,
    Greenlandic or US personnel can work at Thule Air Base and the acquisition
    must be solicited from a contracting office in Denmark to ensure maximum
    opportunity for Danish and/or Greenlandic sources.
    (alteration and footnote added). The Market Research Report further elaborates on the
    context of the relevant international agreements between the United States and Denmark,
    27The “16 July 2008 Diplomatic Note” referred to by Market Research Report, as
    described above, together with the Danish government’s January 27, 2009 response
    constitutes the 2009 Agreement between the United States and Denmark.
    39
    and elaborates on the concerns of the Greenlandic government regarding the United
    States government’s acquisition strategy for the Base Maintenance Contract:
    On March 24, 2015, a Thule Air Base joint statement was signed by The
    Kingdom of Denmark, Greenland, and the United States of America. With
    this statement the three countries made commitments to ensure that the
    Thule Base Maintenance contract in the future is awarded to a
    Danish/Greenlandic source as required by the memorandum of
    understanding between the United States of American and the Government
    of the kingdom of Denmark. On October 28, 2020, the US National Security
    Advisor, Greenlandic Premier, Danish Foreign Minister, and US
    Ambassador to Denmark reached an agreement on the eligibility criterion
    for the Thule BMC as proposed by US Embassy Copenhagen in a
    diplomatic note dated 27 October 2020 (attachment 3).
    According to these criteria an offeror shall be registered as a Danish or
    Greenlandic company in the Danish business register and more than 50%
    of the offeror’s equity shall be owned by Danish or Greenlandic individuals.
    A renewed focus on increasing Greenlandic labor on the Thule BMC is also
    stressed in the diplomatic note, as well as ensuring the contractor maintains
    a physical presence, to include management presence, in Greenland.
    Additionally, in 2020 the Greenlandic Government passed a new law that
    makes it mandatory for businesses in Greenland to inform how many interns
    they have hired. These numbers are released to the general public.
    Even though the Greenlandic Government has mentioned the possibility of
    increasing the Thule BMC workforce to be 60% Greenlandic, 21
    CONS/DET1’s market research indicates this is currently unrealistic. Due to
    other major infrastructure construction in Greenland, including significant
    upgrades to three airports, the number of unemployed skilled Greenland
    labor is at a record low. This combined with the secluded location of Thule
    Air Base with relatively limited opportunities for home leave to visit family, it
    has proven difficult to increase this percentage beyond the current 10-15%.
    (capitalization in original). The Market Research Report additionally provides:
    The Greenlandic home rule holds a high focus on establishing
    apprenticeships for both young and adults in Greenland. In November 2020
    the Greenlandic Government passed a law that will force all companies in
    Greenland to inform how many apprentices they currently have hired. This
    information will be made public in order to hopefully have local industry
    establish more apprenticeships and thus elevate the level of education in
    Greenland.
    As Thule Air Base is located in the defence [sic] area of Greenland it is
    unclear if the base maintenance contractor will have to adhere to this law.
    Greenland Government is currently looking into this.
    40
    (alteration added).
    The Market Research Report states, in section “5. Process and Methodology,”
    under the heading “d. SAM.gov sources sought synopsis,” that a “sources sought
    synopsis was posted on Sam.gov on 20 November 2020,” and that “[t]en (10)
    Danish/Greenlandic companies responded to the sources sought that they are
    interested.” (capitalization and emphasis in original; alteration added). The Market
    Research Report lists the ten “Danish/Greenlandic companies” that responded to the
    market research effort, which includes “Vectrus Services A/S” as a “Danish” company on
    that list. The Market Research Report further includes, in the section “6. Data Analysis
    and Evaluation,” under the heading “a. Interchange meetings with potential offerors,” a
    “synopsis” of information relating to each potential offeror for the Base Maintenance
    Contract, including the following synopsis of protestor Vectrus:
    Vectrus Services is currently the incumbent contractor for the BMC contract
    at Thule Air Base. The company was established in Denmark in 2015 as a
    subsidiary to the US company, Vectrus. They have managed the base since
    2015, when they took over after Greenland Contractors. Their current
    corporate structure does however not meet the anticipated eligibility
    criterion as a Danish/Greenlandic source for the new Base maintenance
    contract. Vectrus Services A/S has a physical location in Greenland.
    (capitalization and emphasis in original).
    The Administrative Record in the above captioned bid protest includes Requests
    for Information issued by the Space Force in anticipation of the issuance of the
    Solicitation. The last Request for Information issued before the Solicitation, which the
    Administrative Record identifies as “Request for Information 004,” dated May 7, 2021,
    and which was publicized for potential offerors’ comment, included a “Draft Performance
    Work Statement” and a “Draft Solicitation Criteria,” both dated May 6, 2021. Included in
    the Draft Solicitation Criteria publicized in Request for Information 004 are eligibility
    criteria which resemble those included in the final Solicitation No. FA2523-21-R-0001, in
    particular the requirements that each offeror
    [c]ertify that at the time of offer submission and annually throughout the term
    of the contract:
    1. it is, and shall remain, registered as a Danish or Greenlandic
    company in the Danish Central Business Register;
    2. more than 50 percent of the offeror’s equity, defined as the entire
    capital of the company, is, and shall continue to be, owned by
    Danish and/or Greenlandic individuals or legal entities; and
    3. a non-Danish or non-Greenlandic individual or legal entity does
    not, and shall not, have a “decisive influence” (in Danish:
    “bestemmende indflydelse”) over the offeror.
    41
    (alteration added). The requirement that an offeror have “more than 50 percent” Danish
    or Greenlandic ownership was consistent with the requirement that would be included in
    the final version of the Solicitation. While the prospective offerors submitted comments
    and questions in response to Request for Information 004, they did not address the
    eligibility criteria in the draft Solicitation.
    The Administrative Record in the above captioned bid protest also includes a
    “Thule Base Maintenance Contract Source Selection Plan” which, according to its
    signature page, was reviewed by Operations Chief Robert Widmann and approved by
    Program Executive Officer Nancy Andrews on November 17, 2021. The Source Selection
    Plan provides at “2.0 ACQUISITION STRATEGY,”
    [t]his source selection will be conducted using FAR 6.302-4 International
    Agreement for other than full and open competition. The source selection
    approach is a Technical/Price Tradeoff (TPT) with one pass/fail Factor. The
    need-date for the new Thule BMC contract is 1 Oct 2023 as the current
    contract expires 30 Sept 2023. A 10-month phase-in period is planned from
    1 Dec 2022 – 30 Sept 2023.
    (capitalization and emphasis in original; alteration added). The Source Selection plan
    states at “5.2.2 Past Performance” that “[p]ast performance will not be evaluated as part
    of this acquisition” and explains:
    This acquisition is restricted to Danish and/or Greenlandic companies IAW
    [in accordance with] an agreement between the U.S. and The Kingdom of
    Denmark. The number of Danish/Greenlandic companies that meet these
    eligibility criteria and that have actual past performance experience for a
    base operations and maintenance contract is limited to a single company.
    The requirements of the Thule Base Maintenance Contract are very mature
    and explicit when it comes to critical utilities. The functional area experts
    have indicated that evaluation of the staffing plan from offerors will be
    sufficient to identify if the offeror can adequately execute the requirements
    of the contract. The infrastructure at Thule is aging and innovation [sic] to
    operate and maintain, given the explicit requirements is [sic] minimal. All
    offerors shall identify in Factor 2, Management, how they plan on retaining
    the current workforce. Historically, the retention ratio from one contract to
    the follow-on contract has been in the high 90th percentile. The latest
    retention ratio was ~98% in 2017 with some individuals working at Thule for
    decades. The retention of the incumbent workforce minimizes risk of not
    conducting past performance.
    (capitalization and emphasis in original; alterations added).
    According to protestor’s bid protest complaint, “[o]n November 17, 2021, the
    Agency issued a ‘Solicitation Notification’ which ‘publicize[d]’ the RFP [Request for
    Proposals].” (second alteration in original). The November 17, 2021 Solicitation
    42
    Notification was attached to protestor’s complaint.28 The Solicitation Notification identifies
    the contracting agency as the Space Force, although the earlier contract was formally
    issued by the Air Force. The Solicitation Notification describes the forthcoming Solicitation
    as “a Request for Proposals (RFPs) for the Thule Base Maintenance Contract (BMC),”
    and provides, in relevant part:
    The planned Thule BMC contains base operations and maintenance
    support requirements for Thule Air Base, Greenland. Base support consists
    of the following services: supply and purchasing, fuels management, airfield
    and airport operations, air traffic and transportation management, water port
    operations, civil engineering operations, vehicle operations and
    maintenance, fire protection, environmental management, health services,
    food services, recreation and community services, and non-sensitive
    communications management.[29]
    28 The Administrative Record in the above captioned bid protest indicates that the
    Solicitation Notification, identified in the Administrative Record index as the Solicitation
    “Cover Letter (November 17, 2021)” should have been included in the Administrative
    Record at Tab 144. Tab 144, however, contains only a duplicate copy of Diplomatic Note
    No. 127. While protestor noted in its motion for judgment on the Administrative Record
    that the Administrative Record “inadvertently” omits the Solicitation Notification, neither
    party moved to include the correct document in the Administrative Record. Because
    neither party objected to the accuracy of the Solicitation Notification as attached to
    protestor’s complaint, and because the Solicitation Notification was intended to be
    included in the Administrative Record, the court, therefore, relies on the version of the
    Solicitation Notification attached to protestor’s complaint.
    29The Contracting Officer’s Statement of Facts, prepared by Contracting Officer Patrick
    R. King for protestor’s prior protest of the Solicitation at the GAO, was included in the
    Administrative Record in the above captioned bid protest, and provides a description of
    the services to be procured by the upcoming Thule Base Maintenance Contract which is
    nearly identical to the description provided in the Solicitation Notification above:
    The Solicitation sought to acquire non-personal base operations and
    maintenance services consisting of supply/fuel (AR Tab 10 at 21, 23) (Id. at
    89, 93), airfield/airport (Id. at 24, 30) (Id. at 35, 36), transportation/seaport
    (Id. at 37, 42), civil engineering (Id. at 53, 88), environmental management
    (Id. at 53, 55), health services (Id. at 106, 115), food services (Id. at 116,
    120), temporary lodging, recreation services (Id. at 121, 126), community
    services (Id. at 127, 129), and non-sensitive communication services (Id. at
    42, 51).
    (emphasis in original). The Contracting Officer’s Statement of Facts also provides that
    “Thule BMC services include all required base support services for the Thule AB [Air
    Base] missions and operations, including sea-launched and intercontinental ballistic
    missile attack warning and assessment, space surveillance and satellite telemetry,
    43
    Participation in this acquisition is restricted to Danish or Greenlandic firms
    only per the terms of an International Agreement between the United States
    and The Kingdom of Denmark. The Statutory Authority is: 10 USC
    2304(c)(4) as implemented by FAR 6.302-4 International Agreement.
    (capitalization in original; footnote added).
    The Contracting Officer’s Statement of Facts, prepared for protestor’s prior protest
    of the Solicitation at the GAO, characterizes the Solicitation as
    a competitive negotiation for a single award, indefinite delivery indefinite
    quantity contract (IDIQ) consisting of Fixed Price (FP) with Economic Price
    Adjustment (EPA) and Firm-Fixed-Price (FFP) line items for Operations and
    Maintenance (O&M) requirements, Cost Reimbursable (CR) line items for
    subsistence and unit supplies, and Time and Material (T&M) line items. The
    approved Requirements Approval Document (RAD) and subsequent ceiling
    of this IDIQ contract is $3.95 Billion, with an initial 5-year ordering period
    from date of award, with options to potentially extend ordering an additional
    seven (7) years through 2 separate option periods.
    According to protestor’s complaint, the Space Force “initially issued the RFP on
    November 17, 2021, and amended the RFP twice (on January 24, 2022[30] and February
    24, 2022).” (footnote added). The Solicitation, as amended through February 24, 2022,
    was attached to protestor’s complaint and included in the Administrative Record.31 As
    relevant to the above captioned bid protest, the Solicitation provides, at item 22,
    “AUTHORITY FOR USING OTHER THAN FULL AND OPEN COMPETITION: FAR
    6.302-4 International Agreem. [sic].” (capitalization in original; alteration added). The
    Solicitation provides no further information regarding the statutory or regulatory basis for
    use of other than full and open competition.
    In “SECTION B – SUPPLIES AND SERVICES AND PRICES/COSTS,” the
    tracking, and command for the Peterson-Schriever Garrison (P-S GAR).” (alteration
    added).
    30 The Solicitation as amended by Amendment 0001, issued January 24, 2022, does not
    appear to be included in full in the Administrative Record in the above captioned bid
    protest, however, the Standard Form 30 effecting Amendment 0001 is included in the
    Administrative Record. The Standard Form 30 for Amendment 0001 indicates that “[t]he
    purpose of this amendment is to implement administrative changes to Solicitation
    FA2523-21-R-0001.” (alteration added).
    31 The Solicitation included in the Administrative Record indicates that it is the version
    current after Amendment 0002, which was issued February 24, 2022. The Solicitation is
    referred to in the index to the Administrative Record as “Solicitation No. FA2523-21-R-
    0001 Conformed Thule BMC Request for Proposal – Amendment 0002 (February 24,
    2022).”
    44
    Solicitation provides:
    B-1    CONTRACT MINIMUM/MAXIMUM AMOUNTS
    The maximum ceiling amount for this contract is DKK 25,605,085,000 (RAD
    Approval Threshold is $3,950,000,000.00). The minimum guaranteed
    amount is DKK 162,058, which will be satisfied at contract award, and is the
    total Government assigned cost of Task Order 0001, Pre-Performance
    Conference.
    B-2    CONTRACT TYPE
    This is an Indefinite Delivery/Indefinite Quantity (IDIQ) contract vehicle.
    Task Orders (TOs) may be placed against this contract in accordance with
    the CLIN structure listed in Section B on a Fixed Price, Cost Type, Time and
    Material, or a hybrid basis.
    (capitalization and emphasis in original). The Solicitation states under the heading “F-2.
    Performance Schedule,” that “[t]his IDIQ contract will be for a 5-year ordering period
    beginning from the date of award. This period may be subsequently extended an
    additional seven (7) years through options.” (capitalization and emphasis in original;
    alteration added). The Solicitation identifies the “Base Ordering Period” as “17 November
    2022 – 30 Sep [sic] 2027,” as well as an “Option Ordering Period 1” as “01 October 2027
    – 30 September 2032,” and an “Option Ordering Period 2” as “01 October 2032 – 16
    November 2034.” (capitalization in original; alteration added).
    Moreover, the Solicitation provides in section “H-6. STATUTORY RESTRICTIONS
    ON FOREIGN ACQUISITIONS,” that “[t]he requirements at PWS 3.1.16 to maximize and
    document contract related purchases and subcontracts from Danish and Greenlandic
    sources is required by the 1962 International Agreement (Aide Memoire) between the US
    and Denmark and takes precedence in the performance of this contract.”32 (alteration
    added). Section H-6 of the Solicitation further incorporates by reference FAR clauses,
    including FAR 52.223-2, “Hazardous Material Identification and Material Safety Data,” in
    the context of “[p]rocurement of Biobased Products,” and DFARS clauses DFARS
    252.225-7012, “Preference for Certain Domestic Commodities,” and DFARS 252.225-
    32 While the Solicitation refers to the 1962 Aide Memoire as constituting an “International
    Agreement” binding “the U.S. and Denmark,” as noted above, neither protestor nor
    defendant in the above captioned bid protest referred to the 1962 Aide Memoire as a
    formal treaty or international agreement. Moreover, the Solicitation does not indicate what
    provisions of the 1962 Aide Memoire require the Base Maintenance Contract “to
    maximize and document contract related purchases and subcontracts from Danish and
    Greenlandic sources,” however, the 1962 Aide Memoire refers to “[i]ncreasing the
    utilization of Danish contractors in the operation of our vital support bases at Thule and
    Sondrestrom,” to increasing “[p]articipation of Danish suppliers in the areas of local
    purchase items and perishable subsistence,” and to “increas[ing] Danish participation in
    competition” for “base repair and maintenance work.” (alterations added).

    7030, “Restriction on Acquisition of carbon, Alloy, and Armor Steel Plate.” (capitalization
    in original; alteration added).
    As relevant to the above captioned bid protest, the Solicitation includes, under
    “SECTION L – INSPECTIONS, CONDITIONS, AND NOTICES TO OFFERORS OR
    RESPONDENTS,” the following requirement:
    L-2. OFFEROR ELIGIBILITY
    Participation in this acquisition is limited to Danish or Greenlandic offerors.
    Through the submission of a memorandum with company letterhead signed
    by an individual who can legally bind the company, offerors must certify that
    at the time of offer submission and throughout the term of the contract:
    a) it is, and shall remain, registered as a Danish or Greenlandic company
    in the Danish Central Business Register; and
    b) more than 50 percent of the offeror’s equity, defined as the entire
    capital of the company, is, and shall continue to be, owned by Danish
    and/or Greenlandic individuals or legal entities; and
    c) a non-Danish or non-Greenlandic individual or legal entity does not,
    and shall not, have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror.
    As part of its offer, an offeror must present a letter from a Danish or
    Greenlandic bank certifying banking service.
    (capitalization and emphasis in original). Under another heading in the same section, “L-
    5. INFORMATION TO OFFERORS (ITO) AND INSTRUCTIONS FOR PROPOSAL
    SUBMISSION,” within subdivision “D. PROPOSAL VOLUME INSTRUCTIONS,”
    paragraph “3. Volume III – Price/Contract Documents (Factor 3),” subparagraph “b.
    Contract Documents,” the Solicitation states that offerors should include, in relevant
    part:
    ii. A letter digitally signed or with a wet signature and scanned copy on
    company letterhead by an individual who can legally bind the company
    certifying that at the time of offer submission and throughout the term of
    the contract:
    1. the offeror is, and shall remain, registered as a Danish or
    Greenlandic company in the Danish Central Business Register; and
    2. more than 50 percent of the offeror’s equity, defined as the entire
    capital of the company, is, and shall continue to be, owned by Danish
    and/or Greenlandic individuals or legal entities; and
    3. a non-Danish or non-Greenlandic individual or legal entity does not,
    and shall not, have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror.
    46
    iii. Signed letter from an officer of a bank within the Kingdom of Denmark
    certifying that your company conducts business with that institution.
    NOTE: ELECTRONIC FUNDS TRANSFER OF INVOICE PAYMENTS
    WILL ONLY BE MADE TO A BANK IN THE KINGDOM OF DENMARK.
    (capitalization and emphasis in original). The letters described in Section L-5(D)(3)(b)(ii)-
    (iii) require the offeror to represent that it meets identical criteria to the eligibility criteria
    included at Section L-2, quoted above. The “more than 50 percent” Danish or Greenlandic
    ownership requirement that appears in both the Section L-2 and Section L-5 eligibility
    criteria in the Solicitation appears exactly as that requirement was set forth in Diplomatic
    Note No. 127.
    Separate from the offeror eligibility factors described above, the Solicitation also
    includes evaluation factors to determine contract award among eligible offerors. In
    “SECTION M – EVALUATION FACTORS FOR AWARD,” under the heading “M-2 BASIS
    FOR CONTRACT AWARD,” the Solicitation states, in relevant part:
    In using the best value approach, the Government seeks to award to the
    offeror who gives the Air Force the greatest confidence that it will best meet
    or exceed our requirements affordably in a way that will be advantageous
    to the Government. This may result in an award to a higher rated, higher
    priced offeror where the decision is consistent with the evaluation Factors
    and the Source Selection Authority (SSA) reasonably determines that the
    superiority of the Management Approach of the higher priced offeror and its
    perceived benefit merits the additional cost. To arrive at a best value
    decision, the SSA will integrate the source selection team’s evaluations of
    the Factors and Subfactors described in this provision. While the
    Government will strive for maximum objectivity, the tradeoff process, by its
    nature, is subjective; therefore, professional judgment is implicit throughout
    the selection process.
    (capitalization and emphasis in original). Under the same heading, the Solicitation further
    states:
    Award will be made to the responsible offeror whose proposal conforms to
    all required terms and conditions, includes all required representations and
    certifications, meets all requirements set forth in the RFP, and provides the
    best value to the Government based on the results of the evaluation as
    described below. To be eligible for award, the offeror must address all
    solicitation criteria and be deemed responsible in accordance with FAR
    9.104.
    (capitalization in original). Also under the M-2 heading, the Solicitation states that “Factor
    2 [Management Approach] is significantly more important than Factor 3, Price.
    Price remains an important consideration in the evaluation.” (capitalization and
    emphasis in original; alteration added). The Solicitation notes three subfactors for Factor
    47
    2, of which “Subfactor 1: Program Management,” evaluates whether the offeror is a
    “Registered Greenlandic Company,” defined as whether the offeror “specifies a valid
    registration from the Central Business Registry (Det Centrale Virksomhedsregister), as a
    registered Business in Greenland.” Another subfactor of Factor 2, “Subfactor 2:
    Greenland Resident Workforce Recruitment and Retention Plan,” evaluates the
    degree to which an offeror would maintain a “physical presence” and a “management
    presence” in Greenland and hire Greenlandic residents as workers. (capitalization and
    emphasis in original). A third subfactor of Factor 2, “Subfactor 3: Apprenticeship
    Program,” evaluates an offeror’s “approach to recruit and motivate young Greenlandic
    residents” to work in apprenticeships at Thule Air Base. (capitalization and emphasis in
    original). Subfactor 2 provides:
    This Subfactor will receive a combined technical/risk rating reflecting the
    extent to which the Greenland Resident Workforce Recruitment and
    Retention Plan, that will be attached to Task Order 0003, Steady State
    BMC, meets or exceeds the following requirements:
    i.    Adequately describes physical presence in Greenland,
    including a management presence necessary to interface
    effectively with the federal and municipal Governments of
    Greenland, the Greenland business community, and other
    entities to maximize recruitment and retention of Greenlandic
    residents.
    ii.   Defines expansion of Greenlandic resident participation in
    terms of number of personnel and disciplines covered as well
    as risks associated.
    iii.   Distinguishable minimum baseline percentage of 10% of
    overall Greenlandic resident workforce, to be met within one
    year of Steady State BMC performance start, with measurable
    annual increases of Greenlandic resident workers.
    Subfactor 3 provides:
    This Subfactor will receive a combined technical/risk rating reflecting the
    extent to which the Apprenticeship Program approach meets or exceeds
    the following requirements:
    i.    Adequately describes how interaction with the federal and
    municipal Governments of Greenland, the Greenlandic
    business community, and other entities maximizes contractor
    outreach.
    ii.   Adequately demonstrates an approach to recruit and motivate
    young Greenlandic residents to choose Thule Air Base as
    location for practical training, and describes quarterly
    recruitment events and retention strategy.
    iii.   Adequately demonstrates a minimum baseline percentage of
    2% of overall workforce to be met within one year of Steady
    48
    State BMC performance start and measurable annual
    increases of Greenlandic resident apprentices.
    In a “NOTICE TO INDUSTRY,” signed by Contracting Officer King, dated January
    11, 2022, and included in the Administrative Record in the above captioned bid protest,
    the Contracting Officer stated that “[t]o expedite responses to industry questions, the
    Space Force Acquisition Team (SFAT) will release Questions and Answers (Q&A) to
    Solicitation FA2523-21-R-0001, Thule Base Maintenance Contract (BMC), in batches as
    responses are finalized.” (capitalization and emphasis in original; alteration added). The
    Administrative Record in the above captioned bid protest includes eight sets of “Request
    for Proposal Questions and Answers,” the first of which is dated in the Administrative
    Record as “November 17, 2021,” the same day that the Solicitation was announced. The
    November 17, 2021 Questions and Answers includes the following question from a
    prospective offeror:
    Previous documents relating to this re-solicitation have indicated there
    would be a Non-cost factor competitive enhancement for offerors
    registered as a Greenlandic source, physical presence in Greenland,
    including management presence . . . fully accounting for the benefits of local
    expertise and knowledge and other non-monetary benefits in the
    competition.
    This draft asks offerors to submit a print of the CBR [Central Business
    Register] indicating if they are a Greenlandic registered company? Q: Is this
    a requirement or an enhancement?
    (capitalization, emphasis, and ellipsis in original; alteration added). The government
    responded: “It is not required to be registered as a Greenlandic company. Danish
    registered companies are allowed. Greenlandic registration would be evaluated as a
    strength.”
    In the fifth set of Questions and Answers, dated January 14, 2022, a prospective
    offeror referred to “Section L-2. OFFEROR ELIGIBILITY” and stated:
    Please confirm that there is a competitive enhancement for an offeror that
    is registered as a Greenlandic source, state the nature and value of the
    enhancement (strength, significant strength, etc.), and state how the USG
    will consider the enhancement in the evaluation and best value
    determination (which factor/subfactor, etc.).
    (capitalization in original). The government responded:
    The Relevant Text cited deals only with the Eligibility Criteria, whereas the
    Comment refers to Section M Evaluation criteria. In order to compete as a
    prime, an offeror has to meet all Eligibility Criteria under Section L-2.
    Whether an offeror is registered as a Business in Greenland will be
    considered under the tradeoff process. For Factor 2, Management
    49
    Approach, Subfactor 1, Program Management, the offeror will receive a
    combined technical/risk rating reflecting the extent to which the program
    management approach for Steady State BMC meets or exceeds all
    identified elements, including whether the offeror is registered as a
    Business in Greenland.
    (capitalization in original). Another question was asked by a prospective offeror which
    also related to Section L-2 of the Solicitation and was identical to the question regarding
    “a competitive enhancement for an offeror that is registered as a Greenlandic source,”
    with the exception that this question referred to “a competitive enhancement for an
    offeror’s physical presence in Greenland (including management presence),” and the
    government provided a response that had the same first two sentences as its prior
    response and continued as follows:
    The Relevant Text cited deals only with the Eligibility Criteria, whereas the
    Comment refers to Section M Evaluation criteria. In order to compete as a
    prime, an offeror has to meet all Eligibility Criteria under Section L-2.
    Whether the proposal adequately describes a physical presence in
    Greenland, including a management presence, will be considered under the
    tradeoff process. For Factor 2, Management Approach, Subfactor 2,
    Greenland Resident Workforce Recruitment and Retention Plan, the offeror
    will receive a combined technical/risk rating reflecting the extent to which
    the Greenland Resident Workforce Recruitment and Retention Plan meets
    or exceeds all identified elements, including whether the plan adequately
    describes physical presence in Greenland, including a management
    presence necessary to interface effectively with the federal and municipal
    Governments of Greenland, the Greenland business community, and other
    entities to maximize recruitment and retention of Greenlandic residents.
    (capitalization in original).
    In the seventh set of Questions and Answers, dated January 19, 2022, prospective
    offerors asked four questions relating to the eligibility criteria at issue in the above
    captioned bid protest. The first question asked:
    Please confirm that a non-Danish or non-Greenlandic individual or legal
    entity does not have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror as long as the non- Danish or non-Greenlandic
    individual or legal entity does not have (1) the power to exercise more than
    half of the voting rights according to an agreement with other investors; (2)
    the power to control the financial and operational decisions of the offeror
    under the Articles of Association or an agreement; (3) the power to appoint
    or remove a majority of the members of the supreme management body,
    and this body exerts a decisive influence on the offeror; or (4) the power to
    exercise the de fact [sic] majority of votes at general meetings or at the
    50
    meetings of an equivalent body, thus exerting de facto decisive influence
    on the enterprise.
    (alteration added). The government responded:
    The United States and the Kingdom of Denmark exchanged diplomatic
    correspondence on this issue. As part of this diplomatic correspondence,
    the eligibility criteria as written in L-2, was formalized and the Space Force
    Acquisition Team was directed to use this criteria by OSD [Office of the
    Secretary of Defense] leadership. There was a footnote included in the
    diplomatic correspondence that reads: Discussed in the Declaration of
    March 19, 2015, submitted by the Kingdom of Denmark to the U.S. Court of
    Federal Claims in Nos. 1:15-cv-00215, 00272 and 00330- CFL. This
    declaration will be provided in the RFP amendment to address the
    comment/question.
    (alteration added). The second question asked:
    Please confirm that the existence and effect of potential voting rights,
    including rights to subscribe for and purchase shares that are currently
    exercisable or convertible, must be taken into account in the assessment of
    whether a company exerts a decisive influence, and that any voting rights
    attaching to the shares owned by the offeror itself or its subsidiaries must
    be disregarded in the calculation of voting rights in the offeror.
    The government’s response to this second question was identical to the response, quoted
    above, given to the first question regarding the eligibility criteria.
    The third question asked: “Please confirm that an individual or legal entity does not
    have a ‘decisive influence’ (in Danish: ‘bestemmende indflydelse’) over the offeror if that
    individual or legal entity does not control or have the power to control the offeror under
    13 C.F.R. 121.103(c).” The government’s response to this third question began, “13 C.F.R
    121.103(c) refers to Small Business Administration (SBA) affiliation determinations. FAR
    Part 19, Small Business Programs, except for subpart FAR 19.6, does not apply to the
    Thule BMC as per FAR 19.000(b),” followed by paragraph which was identical to the
    responses given to the first two questions. The fourth question regarding the eligibility
    criteria asked: “Various provisions in the RFP contemplate teaming arrangements,
    including joint ventures and subcontracting (e.g., L-5(D)(3)(b)(vi)). Please confirm that the
    existence of a contractor team arrangement under FAR 9.601 does not create a ‘decisive
    influence’ (in Danish: ‘bestemmende indflydelse’) over the offeror.” The government
    responded to this fourth question with an identical answer as it had given to the first and
    second questions regarding the eligibility criteria.
    A second “NOTICE TO INDUSTRY,” (capitalization and emphasis in original),
    signed by Contracting Officer King, dated January 19, 2022, and included in the
    Administrative Record in the above captioned bid protest, states that, as of January 19,
    51
    2022, “the Space Force Acquisition Team (SFAT) has completed its responsibility to
    provide answers to questions submitted by the required suspense,” and that “[q]uestions
    received after the suspense will be reviewed and answers may be released as determined
    appropriate by the SFAT.” (alteration added).
    The eighth and final Questions and Answers, dated January 25, 2022, include the
    following question submitted by a prospective offeror: “Please confirm that an individual
    or legal entity does not have a ‘decisive influence’ (in Danish: ‘bestemmende indflydelse’)
    over the offeror if that individual or legal entity does not control or have the power to
    control the offeror under 13 C.F.R. 121.103(c).” This question regarding the eligibility
    criteria is identical to the third question regarding the eligibility criteria asked in the seventh
    set of Questions and Answers, dated January 19, 2022. The January 25, 2022 Questions
    and Answers released by the Space Force offer the government’s “AMENDED
    RESPONSE” to the prospective offeror’s question:
    The United States and the Kingdom of Denmark exchanged diplomatic
    correspondence on this issue. As part of this diplomatic correspondence,
    the eligibility criteria as written in L-2, was formalized and the Space Force
    Acquisition Team was directed to use this criteria by OSD leadership. There
    was a footnote included in the diplomatic correspondence that reads:
    Discussed in the Declaration of March 19, 2015, submitted by the Kingdom
    of Denmark to the U.S. Court of Federal Claims in Nos. 1:15-cv-00215,
    00272 and 00330- CFL. This declaration will be provided in the RFP
    amendment to address the comment/question.
    (capitalization in original). This “AMENDED RESPONSE” is identical to the answers given
    to the first, second, and fourth questions regarding the eligibility criteria asked in the
    January 19, 2022 Questions and Answers, and to the response given to the third question
    regarding the eligibility criteria asked in the January 19, 2022 Questions and Answers,
    except that the government’s “AMENDED RESPONSE” omits the portion of the
    government’s answer to the third question, quoted above, discussing “Small Business
    Administration (SBA) affiliation determinations.” (capitalization in original). The omission
    of the SBA affiliation determinations33 portion of the third answer from the January 19,
    2022 Questions and Answers appears to be the only difference between the January 25,
    2022 “AMENDED RESPONSE” and the third answer from the January 19, 2022
    Questions and Answers. In the January 25, 2022 Questions and Answers, the
    government also responded “Yes” to a question submitted by a proposed offeror asking
    if the government would “provide the legal documents footnoted in the May 2021 US
    Government Sources Sought document,” which appears to be a reference to the
    Declaration of Ambassador Liisberg, described and discussed above. Protestor alleged
    in its complaint that the government “confirmed” in its responses in the January 25, 2022
    33 As noted above, the question of SBA affiliation determinations was raised by a
    prospective offeror to the Solicitation in Questions and Answers on January 19, 2022 and
    January 25, 2022, however, SBA affiliation determinations are not relevant to the issues
    currently before the court.
    52
    Questions and Answers “that the RFP’s eligibility restrictions came from Diplomatic Note
    No. 127,” dated October 27, 2020,” and protestor alleged in its complaint and throughout
    the case currently before the court that “mere ‘diplomatic correspondence’” was the
    basis for the eligibility criteria. (emphasis in original).
    The Administrative Record includes a Standard Form 30 memorializing
    Amendment 0001 of the Solicitation, signed by Contracting Officer King. This Standard
    Form 30 is dated January 24, 2022 and states, at item “14. DESCRIPTION OF
    AMENDMENT/MODIFICATION,” in relevant part:
    AMENDMENT 0001: The offerors [sic] electronic proposal is extended from

    delivered via Procurement Integrated Enterprise Environment (PIEE) to the
    Contracting Officer (CO) listed in section 16A.
    (capitalization and emphasis in original; alteration added).
    The Administrative Record also includes a Standard Form 30 memorializing
    Amendment 0002 of the Solicitation, signed by Contracting Officer Patrick R. King. This
    Standard Form 30 is dated February 24, 202234 and states, at item “14. DESCRIPTION
    OF AMENDMENT/MODIFICATION,” in relevant part:

    2022 and shall be delivered via Procurement Integrated Enterprise
    Environment (PIEE) to the Contracting Officer (CO) listed in section 16A.
    Proposals from new offerors will not be accepted or evaluated.
    (capitalization and emphasis in original). Moreover, the Administrative Record includes a
    “MEMORANDUM FOR THE RECORD,” dated February 24, 2022, which states its subject
    as “Purpose for Amend [sic] 0002 RFP FA2523-21-R-0002 [sic],” and clarifies, in relevant
    part, that the effect of the amendment is that “Danish and Greenlandic sources do not
    have to comply with [DFARS] clauses 252.225-7012 and 252.225-7030.”35 (capitalization
    in original; alterations added).
    34The Standard Form 30 memorializing Amendment 0002 to the Solicitation states the
    “DATE SIGNED” as “24 Feb 2022,” and otherwise refers only to dates in the year 2022,
    but also states the “EFFECTIVE DATE” of the amendment as “24 Feb 2021 [sic]” at the
    top of the first page. (capitalization and emphasis in original).
    35DFARS clauses 252.225-7012, “Preference for Certain Domestic Commodities,” and
    252.225-7030, “Restriction on Acquisition of Carbon, Alloy, and Armor Steel Plate,” are
    53
    Three Performance Work Statements for performance of the Thule Base
    Maintenance Contract, all dated January 24, 2022 are included in the Administrative
    Record and establish the expectations for the successful offeror once the Thule Base
    Maintenance Contract is awarded. The first Performance Work Statement, identified as
    the “Basic Indefinite Delivery Indefinite Quantity (IDIQ)” Performance Work Statement
    (Basic IDIQ Performance Work Statement), includes a “Vision Statement” of “[s]eamless
    and effective operations, maintenance, and support (OM&S) of the Thule Defense Area
    in support of the Thule Air Base (AB) missions in Thule, Greenland.” (capitalization and
    emphasis in original; alteration added). The Basic IDIQ Performance Work Statement
    provides, at section “1.1. Scope:”
    The scope of this requirement is base operations and maintenance services
    consisting of airfield/airport operations, civil engineering, environmental
    management, food services, health services, logistics - supply/fuel, non-
    sensitive communication, seaport, transportation, transient quarters, vehicle
    maintenance, and community/recreation services.
    (emphasis in original). The Basic IDIQ Performance Work Statement provides, at “2.8.
    Contractor Personnel, Disciplines, and Specialties,” in relevant part:
    The contractor shall use Greenlandic employees to the maximum extent
    practical for labor at Thule Air Base, and provide a plan (incorporated at
    contract award) establishing employment targets and methods for
    maximizing these employment targets. The contractor shall participate in
    the Greenlandic Apprenticeship Program and execute their plan
    (incorporated at contract award) to provide outreach to Greenlandic
    employment sectors applicable to labor required on the contractor.
    Contractor shall establish outreach efforts within the business and
    educational communities in Greenland designed to encourage Greenlandic
    employment under the contractor contract to the greatest extent practicable,
    including for placement of apprentices and trainees.
    The contractor shall conduct quarterly outreach with Greenlandic corporate
    social responsibility nongovernmental organization(s), focusing on the
    training and placement of adult trainees age 25 and above (Voksenlærling)
    to maximize the continuity of the Greenlandic workforce through the life of
    the contract.
    (capitalization and emphasis in original). The Basic IDIQ Performance Work Statement
    provides, at “3.16. Purchases and subcontracts from Danish and Greenlandic
    incorporated into the Solicitation at issue and place United States domestic preferences
    on the procurement of goods such as food, clothing, and tents, see DFARS 252.225-
    7012(b) (2022), and “carbon, alloy, or armor steel plate,” see DFARS 252. 225-7030(a)
    (2022), respectively.

    sources:” “Maximize and document contract-related purchases and subcontracts from
    Danish and Greenlandic sources. Required by the 1962 Agreement (Aide Memoire)
    between the Government of the US and the Government of the Kingdom of Denmark.
    Document and justify any exceptions.” (capitalization and emphasis in original).
    The second Performance Work Statement, identified as the “Task Order 0002,
    Phase-In” Performance Work Statement (Phase-In Performance Work Statement),
    includes an identical “Vision Statement” to that included in the Basic IDIQ Performance
    Work Statement. (capitalization and emphasis in original). The Phase-In Performance
    Work Statement, at section “1.1. Scope,” provides that “[t]he scope of this requirement is
    to support phase-in activities for the Steady State BMC Task Order 0003,” followed by a
    list of services identical to the list in the “Scope” section of the Basic IDIQ Performance
    Work Statement. (capitalization and emphasis in original; alteration added). The Phase-
    In Performance Work Statement provides at “3.1.2. Prepare and distribute a Phase-In
    plan” that the awardee must “[p]rovide detailed plan describing the processes for a
    smooth phase-in ensuring no degradation or interruption of services from the incumbent
    contractor to the beginning of performance of Steady State BMC Task Order 3, PWS
    requirements.” (capitalization and emphasis in original; alteration added). The Phase-In
    Performance Work Statement further provides at “3.1.3. Perform Phase-In activities”
    that the awardee must “[c]oordinate with the out-going service provider, the Government
    Transition Team and the Procuring Contracting Officer (PCO) before any transition efforts
    begin. Identify any conflicts to the PCO.” (capitalization and emphasis in original;
    alteration added). The Phase-In Performance Work Statement additionally provides at
    “4.1. Maximize and document contract-related purchases and subcontracts from
    Danish and Greenlandic sources:” “Required by the 1962 Agreement (Aide Memoire)
    between the Government of the US and the Government of the Kingdom of Denmark.
    Document and justify any exceptions.” (capitalization and emphasis in original).
    Moreover, the Phase-In Performance Work Statement provides at “4.3. Phase-In” that
    [t]he Contractor shall follow its Phase-In plan and keep the Government fully
    informed of status throughout the Phase-In period. Throughout the phase-
    in period, it is essential that attention be given to minimize interruptions or
    delays to work in progress that would impact the mission. The contractor
    shall plan for the transfer of work control, delineating the method for
    processing and assigning tasks during the phase-in period.
    (capitalization and emphasis in original; alteration added).
    The third Performance Work Statement, identified as the “Task Order 0003, Steady
    State” Performance Work Statement, (Steady State Performance Work Statement),
    includes an identical “Vision Statement” to that included in the Basic IDIQ and Phase-In
    Performance Work Statements. (capitalization and emphasis in original). The Steady
    State Performance Work Statement, at section “1.1. Scope,” provides that “[t]he scope
    of this requirement is the Steady State of base operations and maintenance services,”
    followed by a list of services identical to the list in the “Scope” sections of the Basic IDIQ
    and Phase-In Performance Work Statements. (capitalization and emphasis in original;
    55
    alteration added). The Steady State Performance Work Statement provides, in relevant
    part, at “2.8. Contractor Personnel, Disciplines, and Specialties,” the same
    requirements with respect to “us[ing] Greenlandic employees to the maximum extent
    practical” as provided in the Basic IDIQ Performance Work Statement. (capitalization and
    emphasis in original; alteration added).
    The Administrative Record in the above captioned bid protest includes the
    proposal submitted by protestor Vectrus in three volumes with numerous attachments.
    The Administrative Record index reflects the date of protestor’s proposal as “February
    16, 2022.”36 Additionally, the Administrative Record includes “Representations and
    Certifications” of protestor,37 protestor’s Danish Central Business Register entry, and
    protestor’s “SAM Registration,” all of which are marked “undated” in the Administrative
    Record. The Administrative Record further reflects that protestor resubmitted its proposal
    on March 7, 2022, following Amendment 0002 to the Solicitation.
    The Administrative Record also includes a “Proposal Receipt Checklist”
    associated with protestor’s February 16, 2022 initial proposal.38 The Proposal Receipt
    Checklist provides a spreadsheet indicating whether protestor’s proposal complied with
    a number of Solicitation criteria, which was noted in a column headed “IAW [in accordance
    with] RFP Yes/No” for each criterion addressed in the spreadsheet. (alteration added).
    With respect to the criteria currently at issue, the Proposal Receipt Checklist spreadsheet
    stated “No” under ““IAW RFP Yes/No,” and provided the “Comment” that “Vectrus
    Services A/S is wholly owned subsidiary of Vectrus Services Corporation (VSC), which is
    an American Company.” (capitalization in original). A second Proposal Receipt Checklist
    is included in the Administrative Record, associated with protestor’s resubmission of its
    proposal following Amendment 0002. The second Proposal Receipt Checklist again
    states “No” with respect to whether protestor’s proposal is “IAW RFP” regarding the
    challenged eligibility criteria, and includes the following comment:
    Vectrus Services Aktieselskab is, and shall remain, registered as a
    Greenlandic company in the Danish Central Business Register.
    Vectrus Services is a wholly owned subsidiary of Vectrus Services
    Corporation (VSC)
    We cherish our Greenlandic community and pledge to continue service to
    that community. Vectrus Services provides benefits to the Greenlandic
    society.
    36Because the above captioned bid protest was a pre-award protest, the Administrative
    Record in this protest does not contain proposals submitted by other proposed offerors.
    37The Representations and Certifications indicate that protestor is owned by Vectrus
    Systems Corporation, which is owned by Vectrus, Inc.
    38The Administrative Record index dates the Proposal Receipt Checklist to February 18,
    2022.
    56
    (alteration added).
    According to protestor’s complaint in the above captioned bid protest, protestor
    filed a protest to what protestor described as the Solicitation’s eligibility criteria in
    “Sections L-2 and L-5(D)(3)(b)(ii)-(iii)” at the GAO on February 11, 2022, alleging that the
    criteria were “unduly restrictive of competition in violation of CICA [Competition in
    Contracting Act] and its implementing regulations.” See Vectrus Servs. A-S, B-420527 et
    al., 
    2022 WL 1639491
     (alteration added). Protestor further alleged in its complaint in the
    bid protest currently before the court that, on February 16, 2022, while protestor’s
    previously-filed protest was pending at the GAO, “the Agency issued an ‘International
    Agreement Competitive Restrictions (IACR)’ document.”
    The IACR was attached to protestor’s complaint and included in the Administrative
    Record in the above captioned bid protest in this court. Although the IACR does not state
    its date of issuance, the IACR is noted in the Administrative Record index with the date
    “February 16, 2022.” The IACR indicates that it was approved by Procuring Contracting
    Officer Patrick R. King39 and Program Manager Jason Parker. The IACR provides that
    the “STATUTORY AUTHORITY” for the eligibility requirements is “10 USC 2304(c)(4)[40]
    as implemented by FAR 6.302-4[41], International Agreement.” (footnotes added).
    39 The IACR identifies Mr. King as both “Procuring Contracting Officer” and as
    “Contracting Officer” at different points.
    40 As noted above, the statute at 
    10 U.S.C. § 2304
     (2018) was moved to

    V.       APPLICABILITY OF AUTHORITY
    The cited exception is applicable under the Defense of Greenland
    Agreement [1951 Agreement]. This primary agreement was entered
    into force on 8 June, 1951 between the United States of America and
    the Kingdom of Denmark (attach 1). In addition to the primary
    agreement, there have been numerous administrative Arrangements
    and supplemental agreements pertaining to the very specific issues
    including the 1962 Aide Memoire (Attach 2), 2009 Diplomatic Note
    [2009 Agreement] (Attach 3) and the 2020 Diplomatic Note
    [Diplomatic Note No. 127] (Attach 4).
    a. International Agreement. The primary agreement is the 1951
    Defense of Greenland Agreement between the US and Denmark.
    This agreement establishes guidelines for participation of Danish
    enterprise and nationals for United States Air Force (USAF) contract
    work supporting defense projects in Greenland. In summary, this
    BMC and other non-sensitive or unclassified services are reserved
    for Danish (including Greenlandic) firms using Danish, Greenlandic
    or US Employees. Danish companies utilizing US employees to meet
    (1) Citations: 10 U.S.C. 3204(a)(4) or 41 U.S.C. 3304(a)(4).
    (2) Full and open competition need not be provided for when
    precluded by the terms of an international agreement or a treaty
    between the United States and a foreign government or international
    organization, or the written directions of a foreign government
    reimbursing the agency for the cost of the acquisition of the supplies
    or services for such government.
    (b) Application. This authority may be used in circumstances such as—
    (1) When a contemplated acquisition is to be reimbursed by a foreign
    country that requires that the product be obtained from a particular
    firm as specified in official written direction such as a Letter of Offer
    and Acceptance; or
    (2) When a contemplated acquisition is for services to be performed,
    or supplies to be used, in the sovereign territory of another country
    and the terms of a treaty or agreement specify or limit the sources to
    be solicited.
    (c) Limitations. Except for DoD, NASA, and the Coast Guard, contracts
    awarded using this authority shall be supported by written justifications and
    approvals described in 6.303 and 6.304.
    FAR 6.302-4.
    58
    contract requirements must first get approval from the Danish
    Ministry of Foreign Affairs to hire US individuals.
    b. Aide Memoire. The 1962 Agreement between the US and Denmark
    is a supplement to the Agreement and established the current
    protocols for participation of Danish enterprise and nationals in
    USAF contract work supporting defense projects in Greenland. In
    summary, the Aid Memoire requires the US to maximize Danish
    participation in contract work and that the purchases shall be
    solicited by a purchasing activity in Copenhagen, Denmark.
    Consequently, this BMC and other non-sensitive/unclassified
    services are reserved for Danish (including Greenlandic) firms only
    using Danish (including Greenlandic) or United States employees
    and are awarded from the Air Force/Space Force contracting office
    in Copenhagen.
    c. Diplomatic Note. The 2008 diplomatic note reiterated the Agreement
    between the US and Denmark by stating that "either party may award
    contracts to commercial enterprises for goods and services,
    including construction projects, in Greenland, and shall procure
    directly from Danish/Greenlandic sources. When procurement from
    such sources is not feasible, US requirements may be satisfied by
    procurement from US or other sources. Either party may use its own
    military or civilian personnel to perform services or construction
    projects." Any changes to the agreements may affect acquisition
    strategy and execution and would have to be addressed if and when
    they arise.
    d. Diplomatic Note. The 2020 diplomatic note clarified the Agreement
    between the US and Denmark by stating what eligibility criteria will
    be applied to be eligible for award of the BMC . . . .
    (capitalization in original; alterations added).
    Protestor’s complaint alleged that on March 17, 2022, while protestor’s bid protest
    was pending before the GAO, the Space Force “revealed that it had evaluated Vectrus’
    proposal as technically unacceptable under the RFP’s eligibility criteria.” According to
    protestor, the Space Force “did not share its ‘Ineligible to Award Determination’ with
    Vectrus until May 24, 2022,” although “Vectrus challenged that determination in a
    Supplemental Protest to the GAO on March 28, 2022.” While protestor alleged that the
    Space Force “evaluated Vectrus’ proposal,” the Space Force’s evaluation of protestor’s
    proposal was limited to a determination of protestor’s eligibility, and the Space Force did
    not assess protestor’s proposal according to the evaluation criteria set forth in Section M
    of the Solicitation. The “Ineligible to Award Determination,” signed by Contacting Officer
    King on May 24, 2022, attached to protestor’s complaint, and included in the
    Administrative Record in the above captioned bid protest, states that the Space Force’s
    “evaluation revealed your [protestor’s] proposal did not comply with solicitation paragraph
    L-5.D.3.b.ii,” and informs protestor of its right to “request a debriefing in accordance with
    FAR 15.505,” with a quotation of paragraph L-5.D.3.b.ii of the Solicitation. (alteration
    59
    added). The “Ineligible to Award Determination” was attached to an email sent by
    Contracting Officer King to Molly Harris, Contracts Manager for protestor, on May 24,
    2022. Protestor’s protest and supplemental protest at the GAO are both included in the
    Administrative Record in the above captioned bid protest.
    On May 18, 2022, the GAO denied both protestor Vectrus’ originally-filed protest
    and its supplemental protest in full in one decision.42 See Vectrus Servs. A-S, B-420527,
    et al., 
    2022 WL 1639491
    , at *1. In its decision denying Vectrus’ protest of the current
    Solicitation, the GAO determined that “[t]he 1991 memorandum of understanding requires
    the Air Force to award contracts at Thule Air Base to Danish or Greenlandic sources,”
    and that “[t]he memorandum of understanding does not define the eligibility criteria a firm
    must meet to be considered a Danish or Greenlandic source.” Id. at *5 (alteration added).
    The GAO noted that while “Vectrus was eligible to compete for the air base maintenance
    contract under those criteria” agreed upon by the United States Embassy and Danish
    Ministry of Foreign Affairs officials for the 2014 Solicitation, “the eligibility criteria defining
    a Danish or Greenlandic source was revised pursuant to diplomatic note 127, to exclude
    wholly owned subsidiaries of foreign firms. When the Air Force issued the Solicitation in
    2020, it therefore used the revised eligibility criteria agreed to in diplomatic note 127.” Id.
    at *6. The GAO concluded that “[a]s Vectrus cannot meet this eligibility criteria, we find
    that the agency reasonably concluded that Vectrus is not eligible to compete for this
    procurement.” Id. (alteration added).
    On May 26, 2022, in a letter sent by Molly Harris, Contracts Manager for Vectrus,
    to Contacting Officer King, protestor “request[ed] a preaward debrief pursuant to FAR
    15.505 Preaward debriefing of offerors,” which Mr. King scheduled for June 7, 2022 in a
    subsequent email to Ms. Harris. (alteration added). Mr. King offered the following
    explanation for determining that protestor’s submission had been ineligible to compete:
    So basically your proposal was compliant in all of the areas of paragraphs
    L-5B, C, D, and E, as stated above, except for L-5D(3)(b)(ii), which was a
    letter digitally signed, or with a wet signature and scanned copy on company
    letterhead by an individual who can legally bind the company, certifying that
    at the time of offer submission and throughout the term of the contract, the
    offeror is and shall remain registered as a Danish/Greenlandic company in
    the central business registry, and more than 50 percent of the offeror’s
    equity, defined as the entire capital of the company, is, and shall continue
    to be, owned by Danish and/or Greenlandic individual or legal entities; and,
    three, a non-Danish or non-Greenlandic individual or legal entity does not,
    and shall not, have a decisive influence (bestemmende indflydelse) over the
    offeror.
    42 Although it is not bound by GAO decisions, the court typically gives respect and
    consideration to GAO decisions. See CBY Design Builders v. United States, 
    105 Fed. Cl. 303
    , 341 (2012) (citing Centech Grp., Inc. v. United States, 
    554 F.3d 1029
    , 1038 n.4 (Fed.
    Cir. 2009) (GAO decisions are “not binding” authority, but may be “instructive in the area
    of bid protests.”))).
    60
    So, I repeat, all other areas were compliant with the RFP from those three
    paragraphs except for that one sub-paragraph. For this reason, in
    accordance with the RFP Paragraph M-3C, the non-compliance of this
    paragraph, as stated in the letter, your proposal was determined to be not
    eligible for award.
    The Administrative Record in the above captioned bid protest includes a
    “COMPETITIVE RANGE DECISION DOCUMENT” for the Thule Base Maintenance
    Contract, which is dated June 1, 2022, signed by Procuring Contracting Officer Patrick R.
    King with the concurrence of Program Manager Jason S. Parker, and approved by Air
    Force Program Executive Officer Nancy K. Andrews. (capitalization and emphasis in
    original). The Competitive Range Decision Document indicates that “[f]our offerors
    submitted proposals in response to the Thule Base Maintenance RFP,” of which three
    were joint ventures. (alteration added). Protestor Vectrus appears twice in the four
    offerors: once as the 49% owner in the joint venture Inuksuk, discussed above, and once
    as a standalone offeror.
    The Competitive Range Decision Document lists the “INITIAL EVALUATION
    RESULTS” for the four offerors according to three factors, “Factor 1 - Technical,” “Factor
    2 – Management Approach,” and “Factor 3 – Price/Contact Documents,” of which
    Factor 1 includes one subfactor, “Subfactor 1 Vehicle Equipment &Replacement [sic],”
    and Factor 2 includes three subfactors, “Subfactor 1 Program Management,”
    “Subfactor 2 Greenland Resident Workforce Recruitment &Retention [sic],” and
    “Subfactor 3 Apprenticeship Program,” while Factor 3 appears to consider “Total
    Evaluated Price,” “Reasonable and Balanced,” and “Completeness,” although these
    phrases, while located under Factor 3, are not denominated subfactors. (capitalization
    and emphasis in original; alterations added). For the first three offerors, an “Adjectival
    Rating” is provided for each of the subfactors listed under Factors 1 and 2, and the ratings
    given include “Unacceptable,” “Good,” and “Outstanding,” while for the fourth offeror,
    protestor Vectrus, the phrase “Not assessed” is listed for every evaluated subfactor.
    (capitalization and emphasis in original). Below Factor 3, for the first three offerors, the
    Initial Evaluation Results list the Total Evaluated Price in Danish kroner, note “TBD” for
    the Reasonable and Balanced evaluation, and state that the proposals are “Complete,”
    while the Initial Evaluation Results only state that protestor Vectrus’ offer, with respect to
    Total Evaluated Price and Reasonable and Balanced, is “Not assessed,” and with
    respect to Completeness, is “Incomplete.” (capitalization and emphasis in original).
    The Competitive Range Decision Document further states:
    Based on these initial evaluation results, all proposals received contained
    findings that did not allow for the award of a contract. Discussions are
    determined to be necessary in order to correct all findings in proposals that
    increase the risk of unsuccessful contract performance.
    The agency evaluated all proposals in accordance with the solicitation.
    Discussions are to be conducted, thus the need to establish the competitive
    61
    range comprised of the most highly rated proposals in accordance with FAR
    15.306(c).
    Moreover, the Competitive Range Decision Document addresses the Space Force’s
    determination with respect to protestor:
    The following offeror was determined ineligible for award for noncompliance
    to the terms and conditions of the RFP and was notified on 24 May 2022 by
    the contracting officer, after approval by the SSA [source selection
    authority], that the proposal was determined ineligible for award for the
    reason stated below:
    Vectrus Services A/S (VS)
    VS is not compliant with the following solicitation requirement RFP
    paragraph L-5.D.3.b.ii:
    A letter digitally signed or with a wet signature and scanned copy on
    company letterhead by an individual who can legally bind the company
    certifying that at the time of offer submission and throughout the term of the
    contract:
    1. the offeror is, and shall remain, registered as a Danish or
    Greenlandic company in the Danish Central Business Register; and
    2. more than 50 percent of the offeror’s equity, defined as the entire
    capital of the company, is, and shall continue to be, owned by Danish
    and/or Greenlandic individuals or legal entities; and
    3. a non-Danish or non-Greenlandic individual or legal entity does not,
    and shall not, have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror.
    The signed letter received from VS in its proposal stated:
    1. Vectrus Services Aktieselskab (A/S) is, and shall remain, registered
    as a Greenlandic company in the Danish central Business Register.
    2. Vectrus Services is a wholly owned subsidiary of Vectrus Services
    Corporation.
    3. We cherish our Greenlandic community and pledge to continue to
    service that community. Vectrus Services provides benefits to the
    Greenlandic society.
    RFP paragraph M-3.3(c) states that all contract documents requested in
    section L-5.D.3.b. will be evaluated but not rated to ensure all documents
    are submitted and completed in their entirety. Failure to submit completed
    version of all documents may render the offeror ineligible for award. The VS
    [Vectrus] letter does not comply with the RFP requirements, because the
    letter does not address whether “more than 50 percent of the offeror’s
    equity, defined as the entire capital of the company, is, and shall continue
    to be, owned by Danish and/or Greenlandic individuals or legal entities” nor
    62
    does the letter address the following criterion: whether “a non-Danish or
    non-Greenlandic individual or legal entity does not, and shall not, have a
    “decisive influence” (in Danish: “bestemmende indflydelse”) over the
    offeror.” It is also apparent that as a wholly owned subsidiary of Vectrus
    Services Corporation, a U.S. company that is headquartered in Colorado
    Springs, Colorado, VS could not certify that it meets the section L-5.D.3.b
    criteria of the solicitation. Given this information the contracting officer
    determined that the offeror was non-compliant to the requirements of the
    RFP and thus ineligible for award. Because VS’s proposal was non-
    complaint [sic] to the requirements of the RFP, no technical or price
    evaluation was conducted on the proposal.
    (capitalization and emphasis in original; alterations added). The Competitive Range
    Decision Document goes on to establish the Competitive Range for the Thule Base
    Maintenance Contract procurement, including all offerors except protestor Vectrus in the
    Competitive Range. The Inuksuk joint venture offeror, of which protestor is a part, but not
    majority, owner, however, was determined eligible for award. Moreover, with respect to
    the “Deficiencies” noted in the Inuksuk proposal, the Competitive Range Decision
    Document states that “[t]he evaluation team believes the findings in Inuksuk A/S’s
    proposal are correctable through discussions.” (capitalization in original; alteration
    added).
    Following denial of the GAO protest, protestor filed the above captioned bid protest
    in this court on June 7, 2022. Protestor’s complaint asserted two causes of action. In
    Count One, “Solicitation Provisions Arbitrarily Restricting Competition in Violation of
    Statute and Regulation,” protestor alleged that the restriction of eligibility to offerors that
    are “more than 50 percent” in terms of capital “owned by Danish and/or Greenlandic
    individuals or legal entities” and without “‘decisive influence’” by non-Danish, non-
    Greenlandic individuals or legal entities, are “restrictions on competition” and that “[t]he
    international agreement exception to CICA [Competition in Contracting Act] did not
    authorize these restrictions on competition because no international agreement required
    the Agency to implement the restrictions.” (capitalization and emphasis in original;
    alterations added) (citing 
    10 U.S.C.A. § 3204
    (a)(4); FAR 6.302-4(a)(2)). Protestor argued
    that the inclusion of the challenged eligibility requirements “was arbitrary, capricious, an
    abuse of discretion, and contrary to law.” In Count Two, “Exclusion from Competition
    Based on Arbitrary and Unlawful Solicitation Provisions,” protestor alleged that, because
    the challenged eligibility criteria are unlawful under the Competition in Contracting Act,
    the Space Force’s “decision to exclude Vectrus from competition” pursuant to the
    eligibility criteria “was therefore arbitrary, capricious, an abuse of discretion, and contrary
    to law.” (capitalization and emphasis in original). For relief, protestor sought a judgment
    “[d]eclaring the RFP’s eligibility criteria and the Agency’s application of that criteria to
    Vectrus’s proposal arbitrary, capricious, an abuse of discretion, and contrary to law,” as
    well as “[e]njoining the Agency to immediately reinstate Vectrus in the competition,” and
    “[e]njoining the Agency to amend the RFP to remove restrictions on competition not
    required by the terms of any international agreement,” as well as “any other relief as the
    Court deems just and proper.” (alterations added).
    63
    Defendant moved to dismiss protestor’s complaint for lack of subject matter
    jurisdiction pursuant to RCFC 12(b)(1), arguing that the court was deprived of jurisdiction
    by operation of the statute at 
    28 U.S.C. § 1502
     (2018), and, in the alternative, that
    protestor’s complaint presented a non-justiciable political question over which this court
    lacks jurisdiction. Protestor and defendant also cross-moved for judgment on the
    Administrative Record. The motions were fully briefed, and the court held oral argument.
    As noted above, due to the urgency of the issues involved in this protest and the indication
    by protestor and defendant that a speedy resolution was necessary, the court issued an
    oral decision on the motion to dismiss and cross-motions for judgment on the
    Administrative Record, which this written Opinion memorializes.
    DISCUSSION
    Defendant’s Motion to Dismiss the Complaint
    In its motion to dismiss protestor’s complaint for lack of subject matter jurisdiction
    pursuant to RCFC 12(b)(1), defendant made two arguments. Defendant first argued that
    “this Court should dismiss the protest pursuant to 
    28 U.S.C. § 1502
    , which bars this Court
    from hearing cases that are dependent upon the Court’s interpretation of a treaty or
    international agreement.” The statute at 
    28 U.S.C. § 1502
     provides: “Except as otherwise
    provided by Act of Congress, the United States Court of Federal Claims shall not have
    jurisdiction of any claim against the United States growing out of or dependent upon any
    treaty entered into with foreign nations.” 
    28 U.S.C. § 1502
     (2018). Defendant asserted
    that “Vectrus’s protest requires this Court to interpret terms” of the 1991 Memorandum of
    Understanding amended by the 2009 Agreement, and defendant argued that “[b]ecause
    Vectrus’ claims are directly dependent upon the meaning of its terms and how the United
    States, Denmark, and Greenland have subsequently interpreted and applied them,
    dismissal is warranted.” (alteration added). In the alternative, defendant argued that
    because the United States Space Force’s definition of the eligibility criteria
    in this RFP stem from international agreements, as well as negotiations and
    exchanges between the United States and North Atlantic Treaty
    Organization (NATO) partner nations in furtherance of strategic national
    defense goals and pursuant to foreign relations objectives, the
    interpretation of the eligibility criteria in this solicitation present [sic] a non-
    justiciable political question upon which this Court should not opine.
    (alteration added).

    court sua sponte.” Folden v. United States,

    , 466 (2020). The Tucker Act, 
    28 U.S.C. § 1491
    , grants jurisdiction to this
    court as follows:
    The United States Court of Federal Claims shall have jurisdiction to render
    judgment upon any claim against the United States founded either upon the
    Constitution, or any Act of Congress or any regulation of an executive
    department, or upon any express or implied contract with the United States,
    or for liquidated or unliquidated damages in cases not sounding in tort.
    
    28 U.S.C. § 1491
    (a)(1) (2018). In addition to the above-stated grounds for jurisdiction, the
    United States Court of Federal Claims has jurisdiction over pre- and post-award protests
    to review solicitations and contract awards issued by federal agencies. See 
    28 U.S.C. § 1491
    (b)(1). The statute at 
    28 U.S.C. § 1491
    (b)(1)-(4) provides:
    (b)(1) Both the Unites [sic] States Court of Federal Claims and the district
    courts of the United States shall have jurisdiction to render judgment on an
    action by an interested party objecting to a solicitation by a Federal agency
    for bids or proposals for a proposed contract or to a proposed award or the
    award of a contract or any alleged violation of statute or regulation in
    connection with a procurement or a proposed procurement. Both the United
    States Court of Federal Claims and the district courts of the United States
    shall have jurisdiction to entertain such an action without regard to whether
    suit is instituted before or after the contract is awarded.
    (2) To afford relief in such an action, the courts may award any relief that
    the court considers proper, including declaratory and injunctive relief except
    that any monetary relief shall be limited to bid preparation and proposal
    costs.
    (3) In exercising jurisdiction under this subsection, the courts shall give due
    regard to the interests of national defense and national security in the need
    for expeditious resolution of the action.
    (4) In any action under this subsection, the courts shall review the agency’s
    decision pursuant to the standards set forth in section 706 of title 5.

    Defendant first argued that 
    28 U.S.C. § 1502
     deprives this court of jurisdiction over
    protestor’s claim. Protestor, however, alleged that the Solicitation eligibility requirements
    violate the Competition in Contracting Act, 
    10 U.S.C.A. § 3201
     et seq. (2022), and its
    implementing regulations. The Competition in Contracting Act provides, at 
    10 U.S.C.A. § 3201
    (a):
    (a) In general.--Except as provided in sections 3203, 3204(a), and 3205 of
    this title and except in the case of procurement procedures otherwise
    expressly authorized by statute, the head of an agency in conducting a
    procurement for property or services--
    (1) shall obtain full and open competition through the use of
    competitive procedures in accordance with the requirements of this
    section and sections 3069, 3203, 3204, 3205, 3403, 3405, 3406,
    3901, 4501, and 4502 of this title and the Federal Acquisition
    Regulation; and
    (2) shall use the competitive procedure or combination of competitive
    procedures that is best suited under the circumstances of the
    procurement.
    
    10 U.S.C.A. § 3201
    (a) (emphasis in original). As relevant to the above captioned bid
    protest, the Competition in Contracting Act further provides at 
    10 U.S.C.A. § 3204
    (a)(4):
    (a) When procedures other than competitive procedures may be
    used.--The head of an agency may use procedures other than
    competitive procedures only when--
    ...
    66
    (4) the terms of an international agreement or a treaty between the
    United States and a foreign government or international
    organization, or the written directions of a foreign government
    reimbursing the agency for the cost of the procurement of the
    property or services for such government, have the effect of
    requiring the use of procedures other than competitive
    procedures[.]
    
    10 U.S.C.A. § 3204
    (a)(4) (emphasis in original; alterations added).43
    Similarly, the FAR, at Part 6, implements the language of the Competition in
    Contracting Act, and the regulation at FAR 6.101, “Policy,” provides:
    (a) 10 U.S.C. 3201 and 41 U.S.C. 3301 require, with certain limited
    exceptions (see subparts 6.2 and 6.3), that contracting officers shall
    promote and provide for full and open competition in soliciting offers and
    awarding Government contracts.
    (b) Contracting officers shall provide for full and open competition through
    the use of the competitive procedure(s) contained in this subpart that are
    best suited to the circumstances of the contract action and consistent with
    the need to fulfill the Government’s requirements efficiently (10 U.S.C. 3201
    43  Both the Competition in Contracting Act and the FAR refer to “an international
    agreement or a treaty between the United States and a foreign government” which may
    affect the requirement for full and open competition. See 
    10 U.S.C.A. § 3204
    (a)(4); FAR
    6.302-4(a)(2), (b)(2). While the words “international agreement” appear to be susceptible
    to interpretation as including informal agreements between the United States and foreign
    governments as well as more formal executive agreements with the force of treaties, the
    Competition in Contracting Act, the FAR, and decisions of this circuit do not define
    “international agreement” as that phrase is used in the international agreement exception
    to the Competition in Contracting’s full and open competition requirement. Moreover, the
    Case-Zablocki Act, 1 U.S.C. § 112a et seq. (2018), requires that the United States
    Department of State maintain “a compilation entitled ‘United States Treaties and Other
    International Agreements,’” know as T.I.A.S., which “shall be legal evidence of the
    treaties, international agreements other than treaties, and proclamations by the President
    of such treaties and agreements, therein contained, in all the courts of the United States,
    the several States, and the Territories and insular possessions of the United States.” 1
    U.S.C. § 112a(a). Both the 1951 Agreement and 2004 Agreement between the United
    States and Denmark are included in T.I.A.S., at T.I.A.S. No. 2,292 and T.I.A.S. No. 04-
    806, respectively. The 1991 Memorandum of Understanding appears at T.I.A.S. No.
    12285, with the dates of July 16, 2008 and January 27, 2009, the dates of the diplomatic
    notes which constitute the 2009 Agreement, listed as the dates of an amendment to the
    1991 Memorandum of Understanding. The 2013 diplomatic correspondence and
    Diplomatic Note No. 127, however, do not appear in T.I.A.S.
    67
    and 41 U.S.C. 3301).
    FAR 6.101 (capitalization in original). The regulation at FAR 6.301, “Policy,” further
    provides:
    (a) 41 U.S.C. 3304 and 10 U.S.C. 3204 each authorize, under certain
    conditions, contracting without providing for full and open competition. The
    Department of Defense, Coast Guard, and National Aeronautics and Space
    Administration are subject to 10 U.S.C. 3204. Other executive agencies are
    subject to 41 U.S.C. 3304. Contracting without providing for full and open
    competition or full and open competition after exclusion of sources is a
    violation of statute, unless permitted by one of the exceptions in [FAR]
    6.302.
    (b) Each contract awarded without providing for full and open competition
    shall contain a reference to the specific authority under which it was so
    awarded. Contracting officers shall use the U.S. Code citation applicable to
    their agency. (See 6.302.)
    (c) Contracting without providing for full and open competition shall not be
    justified on the basis of-
    (1) A lack of advance planning by the requiring activity; or
    (2) Concerns related to the amount of funds available (e.g., funds will
    expire) to the agency or activity for the acquisition of supplies or
    services.
    (d) When not providing for full and open competition, the contracting officer
    shall solicit offers from as many potential sources as is practicable under
    the circumstances.
    (e) For contracts under this subpart, the contracting officer shall use the
    contracting procedures prescribed in 6.102(a) or (b), if appropriate, or any
    other procedures authorized by this regulation.
    FAR 6.301 (alteration added). The regulation at FAR 6.302, “Circumstances permitting
    other than full and open competition,” states: “The following statutory authorities
    (including applications and limitations) permit contracting without providing for full and
    open competition. Requirements for justifications to support the use of these authorities
    are in 6.303.” FAR 6.302. As relevant to the above captioned bid protest, the regulation
    at FAR 6.302-4, “International agreement,” provides:
    (a) Authority.
    (1) Citations: 10 U.S.C. 3204(a)(4) or 41 U.S.C. 3304(a)(4).
    (2) Full and open competition need not be provided for when
    precluded by the terms of an international agreement or a treaty
    between the United States and a foreign government or international
    68
    organization, or the written directions of a foreign government
    reimbursing the agency for the cost of the acquisition of the supplies
    or services for such government.
    (b) Application. This authority may be used in circumstances such as—
    (1) When a contemplated acquisition is to be reimbursed by a foreign
    country that requires that the product be obtained from a particular
    firm as specified in official written direction such as a Letter of Offer
    and Acceptance; or
    (2) When a contemplated acquisition is for services to be performed,
    or supplies to be used, in the sovereign territory of another country
    and the terms of a treaty or agreement specify or limit the sources to
    be solicited.
    (c) Limitations. Except for DoD, NASA, and the Coast Guard, contracts
    awarded using this authority shall be supported by written justifications and
    approvals described in 6.303 and 6.304.
    FAR 6.302-4 (capitalization in original).
    Defendant argued that 
    28 U.S.C. § 1502
     precludes this court from considering
    protestor’s complaint “because it grows out of or is dependent upon the terms of the 1991
    MOU’s definition of Greenlandic/Danish source,” and that, in order to decide the above
    captioned bid protest, “this Court would be required to construe whether the term
    ‘Danish/Greenlandic sources’ in the [2009] amendment to the 1991 MOU includes
    offerors that are subsidiaries of foreign companies.” (alteration added). Defendant argued
    that if protestor’s complaint were not barred by section 1502, “a bid protest could scarcely
    be conceived that would be implicated by Section 1502,” and that “Vectrus’s claim is that
    it was improperly excluded from the competition because of the MOU. In short, the MOU
    is the target, the sum and substance of Vectrus’s complaint.” (emphasis in original).
    Defendant also argued that the Solicitation eligibility criteria “merely reflect the United
    States’ obligation under the agreement.”
    Protestor, in its response to defendant’s motion to dismiss, argued that 
    28 U.S.C. § 1502
    , by its text, does not exclude from this court’s jurisdiction those “claims ‘otherwise
    provided by Act of Congress[.]’” (alteration in original) (quoting 
    28 U.S.C. § 1502
    ).
    Protestor stated that Vectrus “seeks to vindicate its rights in two such Acts, namely, the
    Tucker Act (
    28 U.S.C. § 1491
    (b)(1)),” and the Competition in Contracting Act, 
    10 U.S.C.A. § 3204
    (a)(4). Protestor further argued that “it is only the United States’ defense—and not
    any right of Vectrus—that grows out of an international agreement,” and that “the plain
    language of the statutory bar is limited strictly to a ‘claim against the United States’ and
    does not reasonably include claims that have independent jurisdictional bases, even if
    the United States’ defense may require interpretation of an international agreement.”
    (emphasis in original). Moreover, protestor stated that it “does not challenge the terms of
    the 1991 MOU, as amended [by the 2009 Agreement],” but rather “[i]t challenges the
    Agency’s insertion and subsequent application of unduly restrictive terms in the
    69
    Solicitation.” (alterations added). Protestor claimed that “Section 1502 and case law
    construing it [section 1502], including binding precedent, establishes the exact opposite
    of what the United States argues: the mere fact that adjudicating a claim requires
    interpretation of a treaty or international agreement does not deprive the Court of
    jurisdiction.” (emphasis in original; alterations added). Protestor, citing Wood v. United
    States, 
    961 F.2d 195
    , 199 (Fed. Cir. 1992), argued that “what matters is whether the
    claimed right derives its life and existence from the terms of an international agreement,
    or some other legal authority such as federal statute.” Further, protestor, citing Hughes
    Aircraft Co. v. United States, 
    534 F.2d 889
    , 903-04, 
    209 Ct. Cl. 446
     (1976), argued that
    “
    28 U.S.C. § 1502
     does not mean that any claim requiring the Court to interpret an
    international agreement falls outside the Court’s jurisdiction.” According to protestor, “the
    relevant question is whether the plaintiff’s claimed right—not ‘the defendant’s position’—
    springs from the terms of an international agreement.” (emphasis in original).
    The Supreme Court in United States v. Weld, 
    127 U.S. 51
     (1888), interpreted a
    predecessor to the modern version of 
    28 U.S.C. § 1502
    , identified as “section 1066, Rev.
    St. U. S.,” which deprived the United States Court of Claims of jurisdiction over any “case
    growing out of, and dependent upon,” a treaty of the United States. See United States v.
    Weld, 
    127 U.S. at 54
    . The Supreme Court explained that the Weld claimant “does not
    seek to recover upon any supposed obligation created by” a treaty, “but upon the specific
    appropriation made in” an act of Congress. 
    Id. at 56-57
    . Because the claim in Weld was
    “‘founded upon a law of congress,’” although a treaty was the background of the
    legislation at issue, “such a dependency upon, or growing out of [the treaty], is too remote”
    to be barred by section 1066 of the Revised Statutes. United States v. Weld, 
    127 U.S. at 57
     (capitalization in original; alteration added). The Supreme Court further stated that
    jurisdiction was barred only in the case of “a direct and proximate connection between
    the treaty and the claim,” such that “the right itself, which the petition makes to be the
    foundation of the claim, must have its origin—derive its life and existence—from some
    treaty stipulation.” 
    Id.
     The Supreme Court analogized this requirement to the “rule relating
    to damages in common-law actions; namely, that a wrong-doer shall be held responsible
    only for the proximate, and not for the remote, consequences of his actions.” 
    Id.
    Subsequently, the Supreme Court elaborated on the interpretation of section 1066
    of the Revised Statutes, the same statute at issue in United States v. Weld, 
    127 U.S. 51
    ,
    in Eastern Extension, Australasia & China Telegraph Co. v. United States, 
    231 U.S. 326
    (1913), in which the plaintiff sought to enforce an agreement it previously had made with
    Spain against the United States following the United States’ acquisition of the Philippines
    after the Spanish-American war. The Supreme Court held that insofar “as the petition may
    be viewed as one seeking to assert a claim growing out of the treaty with Spain, we are
    of the opinion that it was not within the jurisdiction of the court of claims.” 
    Id. at 332
    . The
    Supreme Court, however, determined that section 1066 of the Revised Statutes did not
    bar the plaintiff’s claim, because the plaintiff’s allegations could be construed as asserting
    a claim of implied contract alleging that the United States had enjoyed benefits of the
    plaintiff’s cable and telegraph lines which had previously been reserved to the Spanish
    government. See E. Extension, Australasia & China Tel. Co. v. United States, 
    231 U.S. at 334-35
    .
    70
    The United States Court of Claims, in the decision of Falcon Dam Constructors v.
    United States, 
    136 Ct. Cl. 358
    , 
    142 F. Supp. 902
     (1956), relied on the Supreme Court’s
    interpretation of section 1066 of the Revised Statutes to interpret 
    28 U.S.C. § 1502
    , which
    at the time of Falcon Dam Constructors applied to the Court of Claims, but otherwise was
    similar and is relevant to the 
    28 U.S.C. § 1502
     at issue in the current bid protest.44 In
    Falcon Dam Constructors, the Court of Claims dismissed the claim of a Mexican
    corporation which had been awarded a contract for the Mexican portion of the work to
    build a dam on the Rio Grande pursuant to an agreement between the United States and
    Mexico. See Falcon Dam Constructors v. United States, 
    136 Ct. Cl. at 361
    . The Court of
    Claims held that, because the Mexican corporation did not have a contract with the United
    States, but only with Mexico, the Mexican corporation’s claim “grew out of the treaty with
    Mexico” providing for the allocation of costs between the United States and Mexico, and
    the Mexican corporation’s claim was barred by section 1502. See Falcon Dam
    Constructors v. United States, 
    136 Ct. Cl. at 364
    .
    The Court of Claims in another case, Societe Anonyme Des Ateliers Brillie Freres
    v. United States, 
    160 Ct. Cl. 192
     (1963), elaborated on the relationship between a modern
    version of 
    28 U.S.C. § 1502
     and the Supreme Court’s interpretation of section 1066 of
    the Revised Statutes. The Court of Claims in Societe Anonyme explained that “[t]he
    Supreme Court of the United States provided us with an objective standard” with regard
    to “the meaning of section 1502” in the Supreme Court’s decision in United States v.
    Weld, emphasizing that “‘the statute contemplates a direct and proximate connection
    between the treaty and the claim,’” that “‘the right itself, which the petition makes to be
    the foundation of the claim, must have its origin-derive its life and existence-from some
    treaty stipulation,’” and that the rule is analogous to the rule “‘that a wrongdoer shall be
    held responsible only for the proximate and not for the remote, consequences of his
    action.’” Societe Anonyme Des Ateliers Brillie Freres v. United States, 
    160 Ct. Cl. at 197
    (emphasis in original; alteration added) (quoting United States v. Weld, 
    127 U.S. at 57
    ).
    The Court of Claims further stated “that a case growing out of a treaty is one involving
    rights given or protected by a treaty, and is analogous to a case arising under the
    Constitution or laws of the United States.” 
    Id.
     (emphasis in original) (citing United States
    v. Old Settlers, 
    148 U.S. 427
    , 468-69 (1893)). The Court of Claims held that, because the
    claim at issue was based on an entitlement to patent royalties related to World War II, the
    court was not deprived of jurisdiction by 
    28 U.S.C. § 1502
    . See Societe Anonyme Des
    Ateliers Brillie Freres v. United States, 
    160 Ct. Cl. at 197-99
    .
    The Court of Claims applied the interpretation of 
    28 U.S.C. § 1502
     articulated in
    Societe Anonyme in two later cases which have informed subsequent applications of that
    statute: S.N.T. Fratelli Gondrand v. United States, 
    166 Ct. Cl. 473
     (1964), and Hughes
    Aircraft Co. v. United States, 
    209 Ct. Cl. 446
    . The first case, S.N.T. Fratelli Gondrand,
    was a congressional reference case in which the United States Court of Claims held that
    44The statute at 
    28 U.S.C. § 1502
     was amended to refer to the United States Court of
    Federal Claims in the Federal Courts Administration Act of 1992, 
    Pub. L. No. 101-572, § 902
    (a)(1), 
    106 Stat. 4506
    .
    71
    when the claim is based “on the Constitution, the principles governing government
    contracts under the Tucker Act, and the Rules of Land Warfare,” and “[i]t is the
    Government which brings the Treaty to the fore as a defense,” section 1502 “permits the
    court to pass upon a treaty issue raised as a defense to a claim which is independent of
    the treaty. The prohibition is not framed, nor has it been applied, as forbidding this court
    to construe or apply a treaty.” S.N.T. Fratelli Gondrand v. United States, 
    166 Ct. Cl. at 478
     (capitalization in original; alteration added; footnote omitted).45
    In the second case, Hughes Aircraft Co., the United States Court of Claims
    explained:
    The test under s [section] 1502 is whether plaintiff’s claim could conceivably
    exist independently of, or separate and apart from, the subject treaty, or
    whether, on the contrary, it derives its existence so exclusively and
    substantially from certain express terms or provisions thereof, that
    consideration of the claim would necessitate our construction of the treaty
    itself.
    Hughes Aircraft Co. v. United States, 
    534 F.2d at 903
     (alteration added). The Court of
    Claims further stated “that the claim involved must not merely be related to or connected
    with the subject matter of the treaty, but that, absent certain express terms or provisions
    thereof, there could be no claim at all.” 
    Id. at 904
    . The Court of Claims referred to this
    interpretation of section 
    28 U.S.C. § 1502
     as a “narrow construction” and stated that “[i]n
    accord” was the Court of Claims’ decision in Societe Anonyme. See Hughes Aircraft Co.
    v. United States, 
    534 F.2d at 905
     (alteration added) (citing Societe Anonyme Des Ateliers
    Brillie Freres v. United States, 
    160 Ct. Cl. at 196-99
    ). The Court of Claims in Hughes
    Aircraft Co. further held that section 1502 does not bar jurisdiction when the international
    agreement was “only a ‘backdrop’ against which the Government’s allegedly infringing
    activities may be more broadly measured.” Hughes Aircraft Co. v. United States, 
    534 F.2d at 905-06
    .
    In the current protest, however, relying on Hughes Aircraft Co. v. United States,
    
    534 F.2d at 903
    , defendant argued that “Vectrus’ challenge to the eligibility criteria
    necessarily involves analyzing the terms of the agreement as the parties have come to
    interpret it over time,” and, therefore, “Vectrus’ bid protest rises and falls on the parties’
    interpretation of Danish/Greenlandic source in the 1991 MOU.” For this reason, defendant
    45The Court of Claims Judge suggested in a footnote in S.N.T. Fratelli Gondrand that “[i]n
    enacting the predecessor of Section 1502, Congress seems to have been concerned to
    prevent United States citizens from suing directly in the Court of Claims to collect monies
    paid by foreign governments to the United States, under a treaty, in discharge of a class
    of individual claims.” S.N.T. Fratelli Gondrand v. United States, 
    166 Ct. Cl. at
    478 n.3
    (alteration added) (citing Great W. Ins. Co. v. United States, 
    112 U.S. 193
    . 199-200
    (1884)).
    72
    argued, quoting Hughes Aircraft Co. v. United States, 
    534 F.2d at 904
    , “Vectrus’s claim
    derives its ‘life and existence’ from the MOU’s terms.”46
    In its response to the motion to dismiss, protestor, citing Hughes Aircraft Co. v.
    United States, 
    534 F.2d at 903
    , urged that this court should apply a test which Vectrus
    characterizes as “whether the plaintiff’s claim would cease to exist absent the
    international agreement because the right sought to be enforced by the claim is derived
    from that international agreement and not some other source.” Protestor argued that its
    “claim focuses on the unduly restrictive provisions contained in the Solicitation” and that
    its claim is “independent of the 2009 amendment to the 1991 MOU,” because “had the
    Solicitation included the restrictions which Vectrus now challenges in the absence of the
    2009 amendment to the 1991 MOU, the United States would not be able to cite the
    language of that amendment as its defense for restricting competition at all.”
    Subsequent to the Court of Claims’ decision in Hughes Aircraft Co., the United
    States Supreme Court briefly considered the question of the interpretation of 
    28 U.S.C. § 1502
     in the conclusion of its opinion in Dames & Moore v. Regan, 
    453 U.S. 654
    , 688-
    90 (1981). In Dames & Moore, the Supreme Court held, as relevant to the above
    captioned bid protest, that the President possessed the power to settle claims held by
    American individuals and corporations “against foreign governmental entities,” but the
    Supreme Court left open the possibility that such a settlement of a claim could “make ripe
    for adjudication the question whether petitioner will have a remedy at law in the Court of
    Claims under the Tucker Act.” 
    Id. at 688-89
    . The Supreme Court concluded:
    It has been contended that the “treaty exception” to the jurisdiction of the
    Court of Claims, 
    28 U.S.C. § 1502
    , might preclude the Court of Claims from
    exercising jurisdiction over any takings claim the petitioner might bring. At
    oral argument, however, the Government conceded that § 1502 would not
    act as a bar to petitioner's action in the Court of Claims. Tr. of Oral Arg. 39–
    42, 47. We agree. See United States v. Weld, 
    127 U.S. 51
    , 
    8 S. Ct. 1000
    ,
    
    32 L. Ed. 62
     (1888); United States v. Old Settlers,

    534 F.2d 889
    , 
    209 Ct. Cl. 446
     (1976). Accordingly, to the extent petitioner believes it
    has suffered an unconstitutional taking by the suspension of the claims, we
    see no jurisdictional obstacle to an appropriate action in the United States
    Court of Claims under the Tucker Act.

    46 The language of the Court of Claims in Hughes Aircraft Co. which is quoted by
    defendant is itself a quotation of the Supreme Court’s decision in Weld: “for a claim to
    ‘grow out of’ or be ‘dependent upon’ a treaty, ‘the right itself, * * * the foundation of the
    claim, must have its origin—derive its life and existence—from some treaty stipulation.’”

    The Court of Claims’ interpretation of 
    28 U.S.C. § 1502
     in S.N.T. Fratelli Gondrand
    and Hughes Aircraft Co. has been applied in subsequent cases brought in the United
    States Court of Claims, the Federal Circuit, and the United States Claims Court, all to the
    effect that if there is a statute, contract, or other basis for the cause of action asserted
    against the United States, the claim will be considered “independent” of a treaty which
    must be interpreted to decide the case or which otherwise forms the background of the
    claim. See Wood v. United States, 
    961 F.2d at 200
     (holding that although “the Brazilian-
    American Treaty may help to determine whether or not the FAA was obligated to grant a
    certificate of airworthiness on the airplanes,” under the “narrow interpretation” of 
    28 U.S.C. § 1502
     the court had jurisdiction, because “the focus of the claim is that he
    [plaintiff] was not able to purchase them with certificates of airworthiness” and “[t]he treaty
    does not create that right” (alterations added)); see also Brown & Williamson, Ltd. v.
    United States, 
    231 Ct. Cl. 413
    , 421, 
    688 F.2d 747
    , 752 (1982) (holding that “[a]lthough
    the 1980 treaty created the right to a retroactive refund of taxes, it is section 6611 of the
    [Internal Revenue] Code that creates the right to interest upon the refunded taxes” and,
    therefore, a claim for interest on refunded taxes “derives its ‘life and existence’ not from
    the treaty but from section 6611” (alterations added)); Nitol v. United States, 
    7 Cl. Ct. 405
    ,
    417 (1985) (holding that claims based on breach by the United States of a Trusteeship
    Agreement with the United Nations are barred by 
    28 U.S.C. § 1502
     because such claims
    “have no existence that is separate and apart from the Trusteeship Agreement”);
    Anderson v. United States, 
    7 Cl. Ct. 341
    , 343 (1985) (holding that 
    28 U.S.C. § 1502
     barred
    plaintiffs’ claims to the extent they alleged “a taking due to the release of substantially
    more water than authorized by the Treaty,” but the court retained jurisdiction “insofar as
    they allege a taking by inundation apart from the Treaty, because their claims can
    conceivably exist independently of, or separate and apart from, the Treaty”); Peter v.
    United States, 
    6 Cl. Ct. 768
    , 778-79 (1984) (holding that 
    28 U.S.C. § 1502
     barred plaintiffs’
    claims which were “based upon an alleged failure of the United States to comply with
    obligations assumed in the Trusteeship Agreement” with the United Nations, because
    such a claim “clearly grows out of and is dependent upon that treaty,” and such claims
    “have no existence that is separate and apart from the Trusteeship Agreement”); Juda v.
    United States, 
    6 Cl. Ct. 441
    , 453-54 (1984) (holding that 
    28 U.S.C. § 1502
     did not bar
    plaintiffs’ claims against the United States because, while the United States had a
    Trusteeship Agreement with the United Nations which established its fiduciary obligations
    at issue, plaintiffs also alleged the existence of an implied contract with the United States
    which was “distinct” from the Trusteeship Agreement).
    Thereafter, Judges of the United States Court of Federal Claims also have
    interpreted 
    28 U.S.C. § 1502
     consistent with Hughes Aircraft Co. and S.N.T. Fratelli
    Gondrand to the same effect. For example, in Kandel v. United States, 
    133 Fed. Cl. 300
    (2017), a Judge of the Court of Federal Claims held that section 1502 barred the claims
    of Panama Canal Commission employees employed pursuant to a statute which made
    their employment “‘subject to the provisions of the Panama Canal Treaty,’” (quoting 
    22 U.S.C. § 3652
    (a)(1)), but section 1502 did not bar the claims of employees whose
    employment was subject to a later statute that made other employment provisions of the
    United States Code applicable. See Kandel v. United States, 
    133 Fed. Cl. at 303-06
    ; see
    also Dwen v. United States, 
    62 Fed. Cl. 76
    , 83-84 (2004) (holding that section 1502 barred
    74
    plaintiffs’ “‘claim regarding title or possession of real property granted pursuant to a
    treaty,’” (emphasis in original), in which plaintiffs’ entitlement “would originate and dwell
    entirely within the provisions of the treaty”); Adarbe v. United States, 
    58 Fed. Cl. 707
    ,
    719-20 (2003) (holding that so long as “a right stems also from a source that is not a
    treaty, then § 1502 does not prohibit its consideration in this court,” however, “insofar as
    plaintiffs are actually relying on” an international agreement “as the basis for the rights,”
    then “§ 1502 squarely prohibits this court from taking jurisdiction to hear those claims”);
    De Archibold v. United States, 
    57 Fed. Cl. 29
    , 32 (2003) (holding that “because plaintiffs’
    express contract claim is based solely on” an international agreement, “this court does
    not have jurisdiction”).
    In three recent cases cited by the parties, Per Aarsleff A/S v. United States, Kuwait
    Pearls Catering Co., WLL v. United States, and Newimar S.A. v. United States, Judges
    of the Court of Federal Claims have interpreted section 1502 consistent with the Court of
    Claims’ decisions in Hughes Aircraft Co. and S.N.T. Fratelli Gondrand and the other
    cases identified above. As indicated above, a Judge of the Court of Federal Claims
    addressed the issue of section 1502’s application in the Per Aarsleff bid protest litigation
    which involved the predecessor contract to the one at issue in the current litigation, which
    concerned the award of that predecessor contract to Exelis (now protestor Vectrus), and
    in which at the trial court level, the United States in Per Aarsleff argued that the protestors’
    claims in that case were barred by 
    28 U.S.C. § 1502
     as “dependent on an international
    executive agreement.” The Judge of the Court of Federal Claims, however, held that
    “these claims neither directly nor proximately stem from an international agreement.” Per
    Aarsleff A/S v. United States, 
    121 Fed. Cl. at
    622 (citing United States v. Weld, 
    127 U.S. at 57
    ). The Judge of the Court of Federal Claims in Per Aarsleff explained that the court
    “exercises its juridical power to construe the provisions in the Solicitation that were
    explicitly drafted to satisfy and incorporate the international understanding,” and that the
    court would “look to the underlying agreements as a guide to interpreting the text of the
    Solicitation,” but that it would not “be directly enforcing the terms of the bilateral
    agreement between the United States and Denmark.” 
    Id.
     Therefore, the Judge concluded
    that section 1502 did not bar the protestor’s claims. While the Federal Circuit ultimately
    reversed the holding of the Court of Federal Claims in Per Aarsleff, the Federal Circuit
    did not reverse the Court of Federal Claims’ holding with respect to section 1502, nor did
    the Federal Circuit address that issue in its decision on appeal. See generally Per Aarsleff
    A/S v. United States, 
    829 F.3d 1303
    .
    A different Judge of the United States Court of Federal Claims in Kuwait Pearls
    Catering Co., WLL v. United States, 
    145 Fed. Cl. 357
     (2019), interpreted 
    28 U.S.C. § 1502
     in the context of a Fifth Amendment taking claim which the government argued
    “grows out of or depends on the terms of the SOFA [Status of Forces Agreement]”
    between the United States and Iraq. See Kuwait Pearls Catering Co., WLL v. United
    States, 145 Fed. Cl. at 369. The Judge in Kuwait Pearls Catering held that “[a] case grows
    out of or depends upon the terms of a treaty or executive agreement when it involves
    rights ‘given or protected by’ the treaty or executive agreement,” id. (quoting United States
    v. Old Settlers, 148 U.S. at 468) (alteration added), and that “the treaty must create or
    protect the right at issue.” Id. (citing Wood v. United States, 
    961 F.2d at 200
    ; Hughes
    75
    Aircraft Co. v. United States, 
    534 F.2d at 906
    ). Therefore, the Judge in Kuwait Pearls
    Catering interpreted the SOFA and determined that the property which the plaintiff alleged
    had been taken was not covered by the SOFA, see id. at 370, concluding that plaintiff’s
    “taking claim does not grow out of or depend upon the SOFA,” and section 1502 did not
    deprive the court of jurisdiction. Id. at 369-70.
    In a more recent bid protest decision by yet another Judge of the Court of Federal
    Claims, Newimar S.A. v. United States, 
    160 Fed. Cl. 97
     (2022), appeal filed, No. 22-1949
    (Fed. Cir. June 28, 2022), the Judge addressed section 1502’s jurisdictional bar. See
    Newimar S.A. v. United States, 160 Fed. Cl. at 127-28. The discussion of section 1502 in
    Newimar is brief and indicates that the issue was “argued for the first time” in one party’s
    reply brief. See Newimar S.A. v. United States, 160 Fed. Cl. at 127. The Judge in Newimar
    held that the Court of Federal Claims had no jurisdiction over the claim that the awardee
    of the contract “was ineligible for award under the Agreement on Defense Cooperation
    between the United States and the Kingdom of Spain of December 1, 1988 (ADC).” See
    id. at 127. The Judge in Newimar explained that such argument “hinges on an allegation”
    that requirements of the international agreement were not fulfilled, and, therefore, “this
    argument ‘derives its life and existence’ from the Agreement.” Id. at 128. (quoting Hughes
    Aircraft Co. v. United States, 
    534 F.2d at 904
    ).
    Relying on Newimar S.A. v. United States, 160 Fed. Cl. at 127-28, defendant
    argued that the criteria in the Solicitation currently at issue “were derived from the terms
    of the 1991 MOU” including “during diplomatic exchanges culminating in Diplomatic Note
    No. 127,” and that, therefore, “the complaint necessarily calls upon this Court to interpret
    a treaty or international agreement.” Protestor, however, distinguished the above
    captioned bid protest from the discussion of the application of 
    28 U.S.C. § 1502
     in the
    Newimar bid protest, which protestor also characterizes as “dicta.” (emphasis in original).
    Protestor argued that Vectrus, unlike the Newimar claimant, “does not seek to enforce
    the terms of any international agreement,” but “challenges the terms of the Solicitation
    under CICA’s and the FAR’s competition requirements,” under which the Court of Federal
    Claims may review relevant international agreements. This court agrees that the Court of
    Federal Claims’ holding in Newimar may be distinguished from the protest currently under
    review on the grounds that the protestor in this protest did not cite to a treaty or
    international agreement as the basis for its claims, but rather based its claims for relief on
    the Competition in Contracting Act and its implementing regulations. While protestor
    referred to international agreements and treaties between the United States and
    Denmark, it did so to adjudicate whether the requirements of the Competition in
    Contracting Act have been violated by the eligibility requirements included in the
    Solicitation, not to enforce the international agreements and treaties as the claimant in
    Newimar did. See Newimar S.A. v. United States, 160 Fed. Cl. at 127-28.
    As noted above, 
    10 U.S.C.A. § 3204
    (a)(4) allows the government to “use
    procedures other than competitive procedures” when “the terms of an international
    agreement or treaty . . . have the effect of requiring the use of procedures other than
    competitive procedures.” Protestor, in its references to, and quotations from, the treaties
    and international agreements between the United States and Denmark, sought to
    76
    adjudicate the United States’ compliance with the requirements of 
    10 U.S.C.A. § 3204
    (a)(4) in connection with the Solicitation at issue in the above captioned bid protest.
    Defendant, in its reply brief, even seemed to acknowledge this, stating, “the complaint
    asks the Court to interpret the 1991 MOU’s terms in analyzing whether the Space Force’s
    request for proposal’s [sic] (RFP) eligibility criteria are authorized under the Competition
    in Contracting Act” and its implementing regulations. (alteration added). The court, based
    on the above-discussed cases interpreting the application of 
    28 U.S.C. § 1502
    , concludes
    that protestor’s claims “have their origin” and “derive their life and existence” from the
    Competition in Contracting Act at 
    10 U.S.C.A. § 3204
    (a)(4) and its implementing
    regulation at FAR 6.302-4. See United States v. Weld, 
    127 U.S. at 57
    ; Societe Anonyme
    Des Ateliers Brillie Freres v. United States, 
    160 Ct. Cl. at 197
    . Protestor’s claims invoked
    the terms of the United States’ treaties and international agreements with Denmark as
    “only a ‘backdrop’” to protestor’s claims based on statutory and regulatory government
    contract requirements. See Hughes Aircraft Co. v. United States, 
    534 F.2d at 905-06
    .
    Accordingly, this court finds that in the above captioned bid protest, the court is not
    deprived of jurisdiction by 
    28 U.S.C. § 1502
    .
    As noted above, defendant argued, in the alternative, that the court should dismiss
    protestor’s complaint because protestor’s claims presented a political question which is
    non-justiciable and outside the jurisdiction of this court. Defendant argued that “the
    adjudication of the case necessarily invokes second guessing the agreements and the
    diplomatic arrangements between the United States and the Kingdom of Denmark,” and
    that the “agreements and arrangements” between the United States and Denmark with
    respect to Thule Air Base “are decisions that are reserved to the Executive Branch in
    conducting foreign relations and ensuring for the national defense of the United States.”
    Defendant repeated throughout its motion to dismiss and reply brief in support thereof
    that protestor’s complaint “second-guess[es]” the Executive Branch’s negotiations with
    Denmark. (alteration added). According to defendant, foreign relations and national
    defense “decisions are beyond the purview of this Court.” (citing Boumediene v. Bush,
    
    553 U.S. 723
    , 753-54 (2008), Baker v. Carr, 
    369 U.S. 186
    , 211 (1962), and Belk v. United
    States, 
    858 F.2d 706
    , 710 (Fed. Cir. 1988)).
    Protestor argued that “[e]ven assuming a national defense concern existed here,”
    such consideration “relates to injunctive relief, not justiciability,” (alteration added), and,
    therefore, protestor claimed that defendant’s invocation of a national defense concern did
    not create a political question. Protestor also argued that “‘when considering national
    security interests in procurement cases, the Court has typically done so in determining
    whether to provide injunctive relief after exercising jurisdiction and adjudicating the
    merits.’” (quoting Iron Bow Techs., LLC v. United States, 
    136 Fed. Cl. 519
    , 532-33 (2018)
    (internal quotations omitted)). Moreover, according to protestor, defendant “cites no
    evidence or materials” to be included in the administrative record which show “that the
    Court’s decision in this case will have any impact on the national defense.” Protestor
    further argued that, in the October 11, 2016 Memorandum and the 2016 Deputy General
    Counsel Review, “the United States’ own internal legal analysis admits that competitive
    restrictions are rightfully subject to the requirements of CICA, even when they relate to
    international agreements.” According to protestor, citing Defense Technology, Inc. v.
    77
    United States, 
    99 Fed. Cl. 103
    , 116 (2011), “‘where executive conduct is regulated by
    federal statute or regulation,’” judicial review is not precluded by the political question
    doctrine. Protestor argued that “a ruling in its [protestor’s] favor would not preclude the
    United States and the KoD from restricting competition to companies owned by Danish
    or Greenlandic corporate parents in the future,” provided that the United States and
    Denmark sign “a new international agreement that explicitly provides for such.” (alteration
    added).
    The United States Supreme Court in Baker v. Carr, 
    369 U.S. 186
    , stated that a
    nonjusticiable political question “has one or more elements which identify it as essentially
    a function of the separation of powers.” 
    Id. at 217
    . The Supreme Court explained:
    Prominent on the surface of any case held to involve a political question is
    found a textually demonstrable constitutional commitment of the issue to a
    coordinate political department; or a lack of judicially discoverable and
    manageable standards for resolving it; or the impossibility of deciding
    without an initial policy determination of a kind clearly for nonjudicial
    discretion; or the impossibility of a court's undertaking independent
    resolution without expressing lack of the respect due coordinate branches
    of government; or an unusual need for unquestioning adherence to a
    political decision already made; or the potentiality of embarrassment from
    multifarious pronouncements by various departments on one question.
    Unless one of these formulations is inextricable from the case at bar, there
    should be no dismissal for non-justiciability on the ground of a political
    question's presence. The doctrine of which we treat is one of ‘political
    questions,’ not one of ‘political cases.’
    
    Id.
     (alteration added). Further, the Supreme Court in Baker stated, with respect to foreign
    affairs, that
    it is error to suppose that every case or controversy which touches foreign
    relations lies beyond judicial cognizance. Our cases in this field seem
    invariably to show a discriminating analysis of the particular question posed,
    in terms of the history of its management by the political branches, of its
    susceptibility to judicial handling in the light of its nature and posture in the
    specific case, and of the possible consequences of judicial action. For
    example, though a court will not ordinarily inquire whether a treaty has been
    terminated, since on that question ‘governmental action * * * must be
    regarded as of controlling importance,’ if there has been no conclusive
    ‘governmental action’ then a court can construe a treaty and may find it
    provides the answer. Compare Terlinden v. Ames, 
    184 U.S. 270
    , 285, 
    22 S. Ct. 484
    , 490, 
    46 L. Ed. 534
     [(1902)], with Society for the Propagation of
    the Gospel in Foreign Parts v. New Haven, [21 U.S. (]8 Wheat.[)] 464, 492—
    495, 
    5 L. Ed. 662
     [(1823)].
    Baker v. Carr, 
    369 U.S. at 211-12
     (ellipsis in original; alterations added).
    78
    Defendant, in its motion to dismiss protestor’s complaint, argued that protestor’s
    claims present a political question according to the first two “elements” identified by the
    Supreme Court in Baker v. Carr. The first two elements of Baker are whether “a textually
    demonstrable constitutional commitment of the issue to a coordinate political department;
    or a lack of judicially discoverable and manageable standards for resolving it” exist, at
    least one of which must be “inextricable from the case at bar” to dismiss the case on the
    basis of the political question doctrine. See 
    id. at 217
    . The United States Supreme Court
    in Nixon v. United States, 506 US. 224 (1993), explained with respect to the first two
    elements of Baker that
    the concept of a textual commitment to a coordinate political department is
    not completely separate from the concept of a lack of judicially discoverable
    and manageable standards for resolving it; the lack of judicially manageable
    standards may strengthen the conclusion that there is a textually
    demonstrable commitment to a coordinate branch.
    
    Id. at 228-29
     (quoting Baker v. Carr, 
    369 U.S. at 217
    ).
    Defendant argued “that the Constitution grants the Executive Branch the power to
    conduct foreign relations,” and cited to the United States Supreme Court’s decision in
    United States v. Curtiss-Wright Export Corp., 
    299 U.S. 304
     (1936), to define the scope of
    the Executive Branch’s role in foreign relations.47 The Supreme Court stated in Curtiss-
    Wright, in the portion relied upon by defendant:
    It is important to bear in mind that we are here dealing not alone with an
    authority vested in the President by an exertion of legislative power, but with
    such an authority plus the very delicate, plenary and exclusive power of the
    President as the sole organ of the federal government in the field of
    international relations—a power which does not require as a basis for its
    exercise an act of Congress, but which, of course, like every other
    governmental power, must be exercised in subordination to the applicable
    provisions of the Constitution. It is quite apparent that if, in the maintenance
    47 Defendant’s motion to dismiss also argued that “recognizing the sovereignty of other
    countries is textually committed to the political branches,” and for this proposition
    defendant cited to the United States Supreme Court’s decision in Boumediene v. Bush,
    
    553 U.S. 723
    . In the portion of Boumediene v. Bush to which defendant appeared to refer,
    however, the Supreme Court’s decision focused on the question of sovereignty over, and
    the availability of the writ of habeas corpus in, Guantanamo Bay. See 
    id. at 753-54
    .
    Defendant did not elaborate on its argument with respect to Boumediene v. Bush at any
    point in its reply brief, and nothing in defendant’s arguments indicated that protestor’s
    claims, if successful, would deprive the political branches of authority to “recogniz[e] the
    sovereignty of other countries,” as defendant appeared to argue by its citation to
    Boumediene v. Bush. (alteration added). The Supreme Court’s decision in Boumediene
    v. Bush does not resolve the issues in the above captioned bid protest.
    79
    of our international relations, embarrassment—perhaps serious
    embarrassment—is to be avoided and success for our aims achieved,
    congressional legislation which is to be made effective through negotiation
    and inquiry within the international field must often accord to the President
    a degree of discretion and freedom from statutory restriction which would
    not be admissible were domestic affairs alone involved.
    United States v. Curtiss-Wright Export Corp., 
    299 U.S. at 319-20
    . Defendant also cited to
    the United States Court of Appeals for the Federal Circuit’s decision in Belk v. United
    States, 
    858 F.2d 706
    , in which the Federal Circuit upheld the United States Claims Court’s
    dismissal of claims alleging the United States had taken the claimants’ “right to sue Iran
    for injuries sustained while held hostage” by settling those claims to secure the hostages’
    release. See id. at 707. As relevant to the above captioned bid protest, the Federal Circuit
    in Belk relied on the Supreme Court’s holding in Curtiss-Wright that “[t]he President is ‘the
    sole organ of the federal government in the field of international relations.’” Belk v. United
    States, 
    858 F.2d at 710
     (alteration added) (quoting United States v. Curtiss-Wright Export
    Corp., 
    299 U.S. at 320
    ). The Federal Circuit in Belk stated:
    The appellants apparently contend that the President should not have
    entered into the Algiers Accords because he could have obtained better
    terms, and that the Accords themselves were illegal because the President
    was coerced into agreeing to them. The determination whether and upon
    what terms to settle the dispute with Iran over its holding of the hostages
    and obtain their release, necessarily was for the President to make in his
    foreign relations role. That determination was “of a kind clearly for
    nonjudicial discretion,” and there are no “judicially discoverable and
    manageable standards” for reviewing such a Presidential decision. A
    judicial inquiry into whether the President could have extracted a more
    favorable settlement would seriously interfere with the President's ability to
    conduct foreign relations.
    
    Id.
     (quoting United States v. Curtiss-Wright Export Corp., 
    299 U.S. at 320
    ). For this
    reason, the Federal Circuit held that the claims in Belk v. United States presented a
    nonjusticiable political question. See 
    id.
    Vectrus argued that a pair of Supreme Court decisions, Zivotofsky ex rel.
    Zivotofsky v. Clinton, 
    566 U.S. 189
     (2012), and Zivotofsky ex rel. Zivotofsky v. Kerry, 
    576 U.S. 1
     (2015), “require[] rejecting application of the political question doctrine” in
    protestor’s case as articulated in Curtiss-Wright and Belk v. United States, because in the
    above captioned bid protest, the court need only “determine whether the interpretation
    and application of the statute (CICA) is correct, not supplant any foreign policy decision
    by the United States.” (alteration added). Protestor asserted that “[i]t is the judiciary’s sole
    role to determine whether the Executive’s restrictive Solicitation provisions conform to the
    CICA.” (alteration added). Moreover, protestor, citing Zivotofsky v. Kerry, 576 U.S. at 21-
    22, argued that “the ‘sole organ’ or ‘Curtiss-Wright’ doctrine” of presidential authority in
    international relations was “rejected” by the Supreme Court in Zivotofsky v. Kerry.
    80
    In Zivotofsky v. Clinton, the United States Supreme Court rejected the argument
    that a plaintiff’s suit to “vindicate” a “statutory right” created by Congress, “to choose to
    have Israel recorded on his passport as his place of birth,” instead of simply “Jerusalem,”
    presented a nonjusticiable political question. See Zivotofsky v. Clinton, 
    566 U.S. at 195
    .
    The Supreme Court stated:
    The existence of a statutory right, however, is certainly relevant to the
    Judiciary's power to decide Zivotofsky's claim. The federal courts are not
    being asked to supplant a foreign policy decision of the political branches
    with the courts' own unmoored determination of what United States policy
    toward Jerusalem should be. Instead, Zivotofsky requests that the courts
    enforce a specific statutory right. To resolve his claim, the Judiciary must
    decide if Zivotofsky's interpretation of the statute is correct, and whether the
    statute is constitutional. This is a familiar judicial exercise.
    
    Id. at 196
    . The Supreme Court in Zivotofsky v. Clinton considered the first two elements
    of the political question formulation identified in Baker v. Carr in the context of
    “determining the constitutionality of” section 214(d) of the Foreign Relations Authorization
    Act, Fiscal Year 2003, 
    116 Stat. 1350
    , 1366. See Zivotofsky v. Clinton, 
    566 U.S. at 196
    .
    When holding that the claim did not present a nonjusticiable political question, the
    Supreme Court explained:
    Resolution of Zivotofsky's claim demands careful examination of the textual,
    structural, and historical evidence put forward by the parties regarding the
    nature of the statute and of the passport and recognition powers. This is
    what courts do. The political question doctrine poses no bar to judicial
    review of this case.
    
    Id. at 201
    .
    The second case, Zivotofsky v. Kerry, concerned the constitutionality of the same
    statute also at issue in Zivotofsky v. Clinton. The United States Supreme Court in
    Zivotofsky v. Kerry did not further address the political question doctrine discussion from
    its prior decision, however, the Supreme Court did specifically address the significance
    of the Curtiss-Wright decision upon which, as noted above, defendant relies in the cases
    currently before this court. See Zivotofsky v. Kerry, 576 U.S. at 13, 20. While the Supreme
    Court acknowledged that, under Curtiss-Wright, “[t]he President has the sole power to
    negotiate treaties,” id. at 13, 19-20 (alteration added), the Supreme Court limited the
    expansive language of Curtiss-Wright, explaining:
    In support of his submission that the President has broad, undefined powers
    over foreign affairs, the Secretary quotes United States v. Curtiss–Wright
    Export Corp., which described the President as “the sole organ of the
    federal government in the field of international relations.” 
    299 U.S., at 320
    ,
    
    57 S. Ct. 216
    . This Court declines to acknowledge that unbounded power.
    81
    A formulation broader than the rule that the President alone determines
    what nations to formally recognize as legitimate—and that he consequently
    controls his statements on matters of recognition—presents different issues
    and is unnecessary to the resolution of this case.
    Zivotofsky v. Kerry, 576 U.S. at 20. Moreover, according to the Supreme Court in
    Zivotofsky v. Kerry,
    Curtiss–Wright did not hold that the President is free from Congress'
    lawmaking power in the field of international relations. The President does
    have a unique role in communicating with foreign governments, as then-
    Congressman John Marshall acknowledged. See 10 Annals of Cong. 613
    (1800) (cited in Curtiss–Wright, 
    supra, at 319
    , 
    57 S. Ct. 216
    ). But whether
    the realm is foreign or domestic, it is still the Legislative Branch, not the
    Executive Branch, that makes the law.
    In a world that is ever more compressed and interdependent, it is essential
    the congressional role in foreign affairs be understood and respected. For
    it is Congress that makes laws, and in countless ways its laws will and
    should shape the Nation's course. The Executive is not free from the
    ordinary controls and checks of Congress merely because foreign affairs
    are at issue.
    Zivotofsky v. Kerry, 576 U.S. at 21. Although the Supreme Court ultimately struck down
    the statute in question in Zivotofsky v. Kerry as unconstitutionally intruding upon the
    President’s power to recognize foreign governments, the Supreme Court stated that its
    decision did “not question the substantial powers of Congress over foreign affairs in
    general or passports in particular,” and that its decision was “confined solely to the
    exclusive power of the President to control recognition determinations, including formal
    statements by the Executive Branch acknowledging the legitimacy of a state or
    government and its territorial bounds.” Id. at 32.
    Defendant attempted to distinguish the above captioned bid protest from
    Zivotofsky v. Clinton and Zivotofsky v. Kerry by arguing that protestor’s “claim here is an
    attack on a matter well within the power of the Executive Branch to manage foreign and
    security affairs. To suggest that Congress, sub silentio[48] meant to or could have limited
    the powers of the Executive Branch in passing such laws is unimaginable.” (emphasis in
    original; footnote added). According to defendant, the President’s “‘power to speak or
    listen as a representative of the nation,’” “is the very power at issue in this case and
    precisely how the 1991 MOU and its subsequent agreements came into being. They
    should not be disturbed.” (footnote omitted) (quoting Zivotofsky v. Kerry, 576 U.S. at 20).
    48“Sub silentio” is a Latin phrase meaning “under or in silence” or “without notice being
    taken or without making a particular point of the matter in question.” Sub silentio,

    82
    Protestor, however, relies on the Supreme Court’s decision in Japan Whaling
    Association v. American Cetacean Society, 
    478 U.S. 221
     (1986), to argue that because
    “the Court need only interpret the plain language” of the relevant international
    agreements, protestor’s claims do not present a political question. In Japan Whaling
    Association v. American Cetacean Society, the United States Supreme Court reversed
    an order of the United States District Court for the District of Columbia, which had been
    upheld by the United States Court of Appeals for the District of Columbia Circuit, requiring
    the Secretary of Commerce to certify Japan, under 
    16 U.S.C. § 1821
    (e), as a foreign
    nation whose nationals “‘are conducting fishing operations or engaging in trade or taking
    which diminishes the effectiveness of the International Convention for the Regulation of
    Whaling,’” which order had been entered shortly before an agreement was made between
    the United States and Japan not to certify Japan under that statute. See Japan Whaling
    Ass’n v. Am. Cetacean Soc’y, 
    478 U.S. at 226-29
     (quoting 
    16 U.S.C. § 1821
    (e)(2)(A)(i)).
    The Supreme Court rejected the argument that the case presented a political question
    because it “involve[d] foreign relations” and that the federal courts could not “command
    the Secretary of Commerce, an Executive Branch official, to dishonor and repudiate an
    international agreement.” Id. at 229 (alteration added). The Supreme Court stated that
    while “[t]he political question doctrine excludes from judicial review those controversies
    which revolve around policy choices and value determinations constitutionally committed
    for resolution to the halls of Congress or the confines of the Executive Branch,” the
    doctrine did not preclude the courts from interpreting treaties and statutes which have
    impact upon foreign relations. See id. at 230 (alteration added). The Supreme Court
    explained that
    the courts have the authority to construe treaties and executive agreements,
    and it goes without saying that interpreting congressional legislation is a
    recurring and accepted task for the federal courts. It is also evident that the
    challenge to the Secretary's decision not to certify Japan for harvesting
    whales in excess of IWC [International Whaling Commission] quotas
    presents a purely legal question of statutory interpretation. The Court must
    first determine the nature and scope of the duty imposed upon the Secretary
    by the Amendments, a decision which calls for applying no more than the
    traditional rules of statutory construction, and then applying this analysis to
    the particular set of facts presented below. We are cognizant of the interplay
    between these Amendments and the conduct of this Nation's foreign
    relations, and we recognize the premier role which both Congress and the
    Executive play in this field. But under the Constitution, one of the Judiciary's
    characteristic roles is to interpret statutes, and we cannot shirk this
    responsibility merely because our decision may have significant political
    overtones.
    Id. (alteration added). In its reply, defendant appeared to acknowledge that Japan
    Whaling Association stands, as defendant claims, “for the point that courts can interpret
    treaties,” which defendant calls “a general point which with [sic] we do not disagree.”
    (alteration added). At the same time, defendant stated that “Section 1502 precludes”
    interpretation in this protest, and argued that protestor’s argument that “the Court need
    83
    only interpret the plain language of the MOU presents the very problem Section 1502 was
    designed to avoid.”
    Both parties cited to the Federal Circuit’s decision in Aviation & General Insurance
    Co., Ltd. v. United States, 
    882 F.3d 1088
     (Fed. Cir. 2018), as supportive of their
    respective positions on the application of the political question doctrine to the case
    currently under review. The Aviation & General Insurance Co., Ltd. case concerned
    “whether the [United States] Government’s termination of Appellants’ lawsuits [against
    Libya] pursuant to the [Libya] Claims Settlement Agreement between the United States
    and Libya and its subsequent legislation and executive order constituted a compensable
    taking under the Fifth Amendment.” Aviation & Gen. Ins. Co., Ltd. v. United States, 
    882 F.3d at 1090
     (alterations added). Recognizing that the claims could be expressed in two
    ways, the Federal Circuit held “that the question of whether a Fifth Amendment taking of
    Appellants’ alleged property right in their lawsuits occurred presents a justiciable claim,
    but the question of whether Appellants were entitled to proceeds from the Libya Claims
    Settlement Agreement presents a nonjusticiable political question.” 
    Id. at 1094
    . The
    Federal Circuit reasoned that the claimants’ Fifth Amendment taking claims
    do not cause us to question the terms of the Libya Claims Settlement
    Agreement itself, whether the President had authority to enter the
    settlement, or whether the President should have made provision for
    Appellants in the distribution of its proceeds. Rather, these claims require
    us to examine whether, under the Fifth Amendment, a taking occurred by
    the Government's espousal of Appellants’ claims and termination of their
    lawsuits by reinstating Libya's sovereign immunity. This is a legal question
    for which we have judicially discoverable and manageable standards for
    resolution.
    
    Id. at 1095
     (emphasis in original) (citing Baker v. Carr, 
    369 U.S. at 217
    ). The Federal
    Circuit held, “however, that to the extent Appellants seek judicial review of the President's
    decision to exclude them from the settlement’s proceeds, Appellants raise a
    nonjusticiable political question.” 
    Id.
     The Federal Circuit reasoned that “foreign relations
    and settlements to resolve foreign conflicts are soundly committed to the President's
    discretion,” and “the President had complete discretion and authority to implement the
    settlement with Libya and to decide to whom the settlement funds would be distributed.
    Appellants’ argument that they should have been included in the distribution of settlement
    funds questions the President’s policy decision to exclude them.” 
    Id.
     Therefore, according
    to the Federal Circuit, any claims to entitlement to the settlement proceeds from the
    international agreement, but not the Fifth Amendment taking claims, presented a
    nonjusticiable political question. See id. at 1096.
    Protestor argued that the Aviation & General Insurance Co., Ltd. decision indicates
    that protestor’s claim is not a political question, because just as the Federal Circuit held
    that the international agreement at issue in that case “did not bar the Court of Federal
    Claims from hearing the insurers’ Fifth Amendment takings claims,” (emphasis in
    original), protestor’s arguments also “present a legal question for which this Court has
    84
    judicially discoverable and manageable standards for resolution,” in the Competition in
    Contracting Act and its implementing regulations. Protestor argued that it is not
    “questioning whether the United States ‘should have sought better terms’ when
    negotiating,” but rather that “[i]t is asking this Court to determine whether the Agency’s
    actions comport with the terms of a valid Congressional statute and implementing
    regulations.” (capitalization in original; alteration added).
    In its reply brief, defendant alleged that “Vectrus is claiming that the Executive
    Branch could have gotten a better deal in the negotiations” with Denmark, “or that it would
    have achieved a better deal under the Competition in Contracting Act.” According to
    defendant, the Federal Circuit in Aviation & General Insurance Co., Ltd. v. United States,
    
    882 F.3d at 1095
    , held that “second-guessing the deal [between the United States and a
    foreign nation] is not permitted,” and that was the basis for the Federal Circuit’s holding
    with respect to the application of the political question doctrine in that case. (alteration
    added). References to “second-guessing” appear only twice in the published decision of
    the Federal Circuit in Aviation & General Insurance Co., Ltd.: first to describe the
    government’s argument for the application of the political question doctrine, see 
    id. at 1094
     (“The Government argues that both of these arguments present a nonjusticiable
    political question as Appellants ‘attempt to second-guess the President's authority to
    settle [their] claims . . . .’” (capitalization, alteration, and ellipsis in original)), and second
    in the partial concurrence and partial dissent of Judge Reyna, dissenting on the
    application of the political question doctrine on the basis that “permit[ting] suits against
    the U.S. Government that are based on the termination of lawsuits against Libya,”
    according to the partial dissent, “would necessarily involve second guessing the acts of
    the President and Congress, and undermine their negotiating authority to resolve conflicts
    with foreign nations.” 
    Id. at 1106
     (Reyna, J., concurring in part, dissenting in part)
    (alteration added). Moreover, as noted above, the Federal Circuit in Aviation & General
    Insurance Co., Ltd. did not bar claimants’ entire suit on the basis of the political question
    doctrine, but only any claim to entitlement to proceeds from the United States’ settlement
    agreement with Libya, as the Federal Circuit explicitly held that the claimants’ Fifth
    Amendment taking claims were justiciable. See 
    id. at 1095-96
    . Therefore, defendant’s
    argument that the Federal Circuit’s holding in Aviation & General Insurance Co., Ltd.
    generally prohibits suits related to international agreements as “second-guessing” the
    government mischaracterizes that decision and the law regarding the political question
    doctrine.
    Protestor additionally relied on two United States Court of Federal Claims cases
    to argue that its claims do not present a nonjusticiable political question. In the first case,
    Kuwait Pearls Catering Co., WLL v. United States, also discussed above, the Judge of
    the Court of Federal Claims considered whether the plaintiff’s Fifth Amendment taking
    claim presented a nonjusticiable political question by “attempting to ‘second-guess the
    SOFA [Status of Forces Agreement] that the President entered into with the Iraqi
    Government.’” Kuwait Pearls Catering Co., WLL v. United States, 145 Fed. Cl. at 370
    (alteration added). The Judge in Kuwait Pearls Catering held that a political question was
    not presented, explaining that “[a]t issue in this case is whether the Government effected
    a taking of KPCC’s [Kuwait Pearls Catering Co.’s] property, entitling KPCC to just
    85
    compensation. What is not at issue is the wisdom of the SOFA itself, nor the executive
    branch's decision-making regarding foreign relations.” Id. (capitalization in original;
    alterations added). Moreover, because the Kuwait Pearls Catering case concerned a
    claim for a Fifth Amendment taking, the Judge determined that “there are judicially
    manageable standards governing resolution of KPCC's claim.” Id. at 371.
    In the second case cited by protestor, Defense Technology, Inc. v. United States,
    
    99 Fed. Cl. 103
    , a Judge of the Court of Federal Claims considered at length whether all
    six of the Baker v. Carr elements applied to a bid protest of a sole-source contract
    awarded to a Russian state-owned company for the purchase of helicopters. 
    Id. at 116
    .
    The United States in Defense Technology cited “the ‘longstanding doctrine that decisions
    grounded in defense and foreign policy are responsibilities of the executive branch and
    . . . not subject to judicial review,’” and “argue[d] that the political question doctrine bars
    this Court from reviewing plaintiff’s claims in this case.” 
    Id. at 115
     (ellipsis in original;
    alteration added). The Judge of the Court of Federal Claims in Defense Technology
    rejected the application of the political question doctrine, explaining that “[w]hile the
    political question doctrine renders many executive decisions over defense and foreign
    policy outside the province of the courts,” the government’s argument “that the foreign
    and defense spheres are ‘textually committed by the Constitution to the political
    branches,’” was “overstated at best,” and that “where executive conduct is regulated by
    federal statute or regulation—in any sphere—and the courts are presented with an
    appropriate controversy, the Constitution requires the courts to take jurisdiction and apply
    the law.” 
    Id. at 116
    . (alteration added) (citing Clinton v. Jones, 
    520 U.S. 681
    , 703 (1997)).
    According to the Judge in Defense Technology, “merely invoking foreign policy or national
    defense is insufficient to place an issue beyond judicial review,” id. at 117, and explained
    that “it is well established that the Administrative Procedure Act, 
    5 U.S.C. § 706
     and the
    FAR apply to and govern bid protests against Department of Defense procurements,” and
    that “no court has questioned the constitutionality of judicial oversight of federal defense
    procurements.” Def. Tech., Inc. v. United States, 
    99 Fed. Cl. at 117
    .
    In sum, the United States Supreme Court in Baker v. Carr explained that “it is error
    to suppose that every case or controversy which touches foreign relations lies beyond
    judicial cognizance.” Baker v. Carr, 
    369 U.S. at 211-12
    . When a claim is based on “[t]he
    existence of a statutory right,” as protestor in the above captioned protest claimed its
    asserted right is based on the Competition in Contracting Act, that right “is certainly
    relevant to the Judiciary's power to decide [the] claim.” Zivotofsky v. Clinton, 
    566 U.S. at 196
     (alterations added). When a claim is based on a statutory right, “[t]he federal courts
    are not being asked to supplant a foreign policy decision of the political branches,” but
    rather to “enforce a specific statutory right,” which “is a familiar judicial exercise.” 
    Id.
    (alteration added). Moreover, “[t]he Executive is not free from the ordinary controls and
    checks of Congress merely because foreign affairs are at issue.” Zivotofsky v. Kerry, 576
    U.S. at 21 (alteration added). Among these “ordinary controls” is the Competition in
    Contracting Act, including the Competition in Contracting Act’s requirement that “an
    agency may use procedures other than competitive procedures” when “the terms of an
    international agreement or a treaty between the United States and a foreign government
    . . . have the effect of requiring the use of procedures other than competitive procedures,”
    86
    
    10 U.S.C.A. § 3204
    (a)(4) (ellipsis added). Defendant’s invocation of foreign policy
    concerns in the context of the political question doctrine does not avoid the application of
    the Competition in Contracting Act to the Solicitation currently at issue, as the statutory
    language at 
    10 U.S.C.A. § 3204
    (a)(4) expressly applies to the application of treaties and
    international agreements to public procurement. See Def. Tech., Inc. v. United States, 
    99 Fed. Cl. at 117
    . The application of 
    10 U.S.C.A. § 3204
    (a)(4) “do[es] not cause us to
    question” the result of the United States’ negotiations with Denmark. See Aviation & Gen.
    Ins. Co., Ltd. v. United States, 
    882 F.3d at 1090
     (alteration added). With “the authority to
    construe treaties and executive agreements,” in the appropriate circumstances, this court
    may interpret the international agreements between the United States and Denmark to
    determine the application of the treaties or agreements which impact the United States’
    procurement for goods and services at Thule Air Base, see Japan Whaling Ass’n v.
    American Cetacean Soc’y, 
    478 U.S. at 230
    , and the nature and impact of the included
    language “is a legal question for which” section 3204(a)(4) provides “judicially
    discoverable and manageable standards for resolution.” Aviation & Gen. Ins. Co., Ltd. v.
    United States, 
    882 F.3d at 1090
     (emphasis in original); see also Baker v. Carr, 
    369 U.S. at 217
    ; Kuwait Pearls Catering Co., WLL v. United States, 145 Fed. Cl. at 371.
    Accordingly, the court holds that protestor’s raised claims do not present a nonjusticiable
    political question. Therefore, the court concludes that defendant’s motion to dismiss the
    protest for lack of subject matter jurisdiction is denied in its entirety.
    The Parties’ Cross-Motions for Judgment on the Administrative Record
    As noted above, both parties cross-moved for judgment on the Administrative
    Record. RCFC 52.1 governs motions for judgment on the Administrative Record. The
    court’s inquiry is directed to “‘whether, given all the disputed and undisputed facts, a party
    has met its burden of proof based on the evidence in the record.’” Mgmt. & Training Corp.

    Section 706(2)(A) requires a finding that the actual choice made was not
    “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance
    with law.” To make this finding the court must consider whether the decision
    was based on a consideration of the relevant factors and whether there has
    been a clear error of judgment. Although this inquiry into the facts is to be

    10 U.S.C.A. § 3204
    (a)(4) (ellipsis and alteration added). The Solicitation at issue in the
    case before the court includes criteria at section “L-2. OFFEROR ELIGIBILITY,” that
    require each offeror to certify, for the duration of performance, that:
    a) it is, and shall remain, registered as a Danish or Greenlandic company
    in the Danish Central Business Register; and
    b) more than 50 percent of the offeror’s equity, defined as the entire capital
    of the company, is, and shall continue to be, owned by Danish and/or
    Greenlandic individuals or legal entities; and
    c) a non-Danish or non-Greenlandic individual or legal entity does not, and
    shall not, have a “decisive influence” (in Danish: “bestemmende
    indflydelse”) over the offeror.
    (capitalization and emphasis in original). The three challenged requirements of the
    eligibility criteria at Section L-2 also are found at Section L-5(D)(3)(b)(ii) of the Solicitation
    as quoted above. Protestor’s failure to comply with the criteria as set forth at Section L-
    5(D)(3)(b)(ii) of the Solicitation is cited by Contracting Officer King in the May 24, 2022
    Ineligible to Award Determination as the reason for Vectrus’ exclusion from the
    competition under the Solicitation.
    The parties offered differing interpretations of the Competition in Contracting Act
    for the court to apply to the above captioned bid protest. Protestor argued that “CICA
    allows agencies to restrict competition only to the extent required by the terms of an
    international agreement,” although “parties [to an international agreement] may adopt a
    more restrictive interpretation by executing a new international agreement or an
    amendment to an existing agreement.” (alteration added). Protestor argued, however,
    that “the United States and the KoD did not do so here.” Protestor further argued that
    [e]ven assuming the term “Danish/Greenlandic sources” in the amended [in
    2009] MOU is subject to two interpretations (either excluding American-
    owned companies or not), CICA requires the Agency to adopt the less
    restrictive interpretation because the “terms” (Danish/Greenlandic sources)
    of the “international agreement” (the amended MOU) do not “have the effect
    of requiring” the more restrictive interpretation (limiting competition to only
    Danish or Greenlandic-owned, rather than Danish-registered, companies).
    (emphasis in original; alterations added). According to protestor, “CICA requires the
    United States to interpret the words ‘Danish/Greenlandic sources’ [from the 2009
    Agreement] to provide for as much competition as is practicable,” and “[t]o do otherwise
    would result in restricting competition where ‘the terms’ of an ‘international agreement’ do
    not, in fact, ‘have the effect of requiring’ the restriction.” (alterations added) (quoting 
    10 U.S.C.A. § 3204
    (a)(4)). Defendant, in response, argued that “[t]he Court must consider
    whether the decision” to include the challenged eligibility criteria in the Solicitation
    pursuant to its exchange of documents and discussion with the Kingdom of Denmark
    “was based upon consideration of the relevant factors and whether there has been a clear
    93
    error in judgment.” (citing Citizens To Pres. Overton Park, Inc. v. Volpe, 
    401 U.S. at 416
    ).
    Defendant further argued regarding inclusion of the eligibility criteria in the Solicitation,
    that “the decision [by the United States] is entitled to a ‘presumption of regularity,’”
    (alteration added) (quoting Citizens To Pres. Overton Park, Inc. v. Volpe, 
    401 U.S. at 415
    )
    such “that the Court should not substitute its judgment for that of the agency.” (citing
    Cincom Sys., Inc. v. United States, 
    37 Fed. Cl. 663
    , 672 (1997)).
    Regarding the international agreement exception to the Competition in Contract
    Act, and the interpretation of treaties and international agreements thereunder, the court
    in the above captioned bid protest ordered supplemental briefing from the parties after
    their initial briefings. The court has reviewed numerous cases which address the treaty
    interpretation issues presented by this bid protest, however, none have been identified as
    directly dispositive in the case before this court.50 The language of the international
    agreement exception, however, calls for the court to interpret “the terms of an
    international agreement” cited by defendant, the 2009 Agreement, and the others raised
    by the parties in this case, the 1951 Agreement, the 1991 Memorandum of
    Understanding, and the 2004 Agreement, in order to determine whether or not the
    agreements “have the effect of requiring” the challenged eligibility criteria. See 
    10 U.S.C.A. § 3204
    (a)(4).
    The historical sequence of international agreements relevant to the Solicitation at
    issue in the above captioned bid protest are the 1951 Agreement, the 1991 Memorandum
    of Understanding, the 2004 Agreement, and the 2009 Agreement, all four of which the
    protestor and defendant agreed are binding agreements between the United States and
    Denmark. As described above, the 1951 Agreement is the foundational agreement for
    United States military operations in Greenland, and states that the United States “agrees
    to cooperate to the fullest degree with” Denmark “in carrying out operations under this
    Agreement,” and provides for “[q]uestions of interpretation” to be “submitted to the
    Minister for Foreign Affairs of the Kingdom of Denmark and to the United States
    Ambassador to Denmark.” See 1951 Agreement, art. VI at 9, art. XIII at 13 (alteration
    added). The 2004 Agreement, which amends the 1951 Agreement, provides that, for
    disputes related to the United States’ military presence in Greenland, “the Parties shall
    consult with each other either in the Permanent Committee or through diplomatic
    channels, as appropriate.” See 2004 Agreement, art. 3, ¶ 2.b. The 1991 Memorandum of
    Understanding provided for the establishment of the Permanent Committee for the
    50 There are two decisions issued by Judges of the United States Court of Federal Claims
    interpreting a different provision of the international agreement exception to the
    requirement of full and open competition, which applies when “the written directions of a
    foreign government reimbursing the agency for the cost of the procurement of the
    property or services for such government, have the effect of requiring the use of
    procedures other than competitive procedures,” 
    10 U.S.C.A. § 3204
    (a)(4), but the
    statutory provision interpreted in the two cases is not the same as in the above captioned
    bid protest. See Hyperion, Inc. v. United States, 
    120 Fed. Cl. 504
    , 511-14 (2015)
    (discussing 
    10 U.S.C. § 2304
    (c)(4) (2012)); L-3 Comm’ns Corp. v. United States, 
    99 Fed. Cl. 283
    , 289-91 (2011) (discussing 
    10 U.S.C. § 2304
    (c)(4) (2006)).
    94
    resolution of disputes as well as for the referral of “problem[s] which cannot be resolved
    by the Permanent Committee” to “diplomatic channels.” (alteration added). See 1991
    Memorandum of Understanding, art. VII. The 1991 Memorandum of Understanding also
    originally provided that the United States and Denmark “may procure directly from any
    US or Danish/Greenlandic source and may use its own military or civilian personnel to
    perform services or construction projects.” See 
    id.
     art. IV. The 2009 Agreement amended
    the 1991 Memorandum of Understanding to replace this provision with the requirement
    that the United States and Denmark “shall procure directly from Danish/Greenlandic
    sources.” The 2009 Agreement is the most recent of the bilateral diplomatic agreements
    between the United States and Denmark, which both parties agreed is dispositive.
    Additionally, the United States and Denmark have continued to engage in frequent
    diplomatic correspondence and discussions since the 2009 Agreement regarding how to
    conduct competition for the Base Maintenance Contract at Thule Air Base in Greenland.
    As described above, the relevant highlights include that in December 2013, the United
    States and Denmark exchanged letters in which the governments interpreted the term
    “Danish/Greenlandic sources” from the 2009 Agreement and agreed upon offeror
    eligibility criteria to use in the procurement of the earlier contract awarded to Exelis, as
    protestor Vectrus was previously known. In 2020, the United States and Denmark once
    again exchanged diplomatic correspondence, and the United States sent Diplomatic Note
    No. 127, dated October 27, 2020, to establish new offeror eligibility criteria for contracting
    for the Thule Base Maintenance Contract in the Solicitation at issue in the above
    captioned bid protest, which the Danish government accepted the same day, October 27,
    2020.
    Protestor argued that the court’s interpretation should focus on the plain text of the
    2009 Agreement and states that “‘[t]he interpretation of a treaty, like the interpretation of
    a statute, begins with its text.’” (alteration added) (quoting Medellin v. Texas, 
    552 U.S. 491
    , 506 (2008)). Protestor argued that “the plain language of” the phrase
    “Danish/Greenlandic sources,” “do [sic] not have ‘the effect of requiring’ the restrictions in
    Sections L-2 and L-5(D)(3)(b)(ii)-(iii) of the RFP.” (alteration added) (quoting 
    10 U.S.C.A. § 3204
    (a)(4)). Protestor further argued that while “[t]he amended MOU does not define
    ‘sources,’” in the context of procurement law, “it refers to entities which provide goods or
    services, not their corporate parents.” (alteration added) (citing 
    10 U.S.C.A. §§ 3011
    (5),
    3204(a)(3); FAR 2.101). Therefore, protestor argued, “[r]eading the text consistent with
    the context surrounding the word ‘sources,’ the term ‘Danish/Greenlandic sources’ refers
    to entities providing goods or services which are themselves Danish or Greenlandic. The
    term does not have the effect of requiring corporate parents or affiliates to be Danish or
    Greenlandic.” (alteration added).
    Protestor argued that “[b]y contrast, reference to sources ‘beyond the written
    words’ of the agreement such as ‘the history of the treaty, the negotiations, and the
    practical construction adopted by the parties’ are [sic] only appropriate where the text
    itself is indeterminate.” (alterations added) (quoting E. Airlines, Inc. v. Floyd, 
    499 U.S. 530
    , 534-35 (1991); citing Xerox Corp. v. United States, 
    41 F.3d 647
    , 652 (Fed. Cir. 1994),
    cert. denied, 
    516 U.S. 817
     (1995)). Moreover, protestor argued that “the Court must
    95
    determine the meaning of the amended MOU as of the time it was executed,” (emphasis
    in original) (citing Wash. St. Dep’t of Licensing v. Cougar Den, Inc., 
    139 S. Ct. 1000
    , 1016
    (2019) (Gorsuch, J., concurring)), because “[i]t is ‘well established that parties’ post-treaty
    actions are relevant only insofar as they reflect on the determinative issue, the parties’
    intent at the time the treaty was signed.’”51 (emphasis in original; alteration added)
    (quoting United States v. Smiskin, 
    487 F.3d 1260
    , 1268 (9th Cir. 2007); citing Choctaw
    Nation of Indians v. United States, 318 U.S. at 432).
    In its cross-motion for judgment on the Administrative Record, defendant argued
    that the “eligibility criteria are the result of many discussions and negotiations by the
    Departments of Defense and State on behalf of the United States executive branch’s
    foreign relations role with the Kingdom of Denmark, including Greenland on what
    constitutes a Danish/Greenlandic source.” According to defendant, “[c]onsistent with the
    bilateral framework developed over time, and most recently, culminating in Diplomatic
    Note 127, the countries developed a shared understanding on how to implement the
    definition of Danish/Greenlandic source and included it in the Thule BMC RFP.”
    (alterations added). Therefore, defendant argued, the challenged criteria in the
    Solicitation currently under review “fall squarely within” the international agreement
    exception to the Competition in Contracting Act.
    The parties disagreed as to the impact of diplomatic exchanges between the
    United States and Denmark which occurred after the execution of the 2009 Agreement,
    as well as after the earlier 1951 Agreement, the 1991 Memorandum of Understanding,
    and the 2004 Agreement. Protestor argued that “post-execution documents and actions
    are weak evidence of meaning because of their temporal relationship to the international
    agreement, and they grow weaker with age.” (emphasis in original) (citing GE Energy
    Power Conversion France SAS, Corp. v. Outokumpu Stainless USA, LLC, 
    140 S. Ct. 51
     In protestor’s supplemental brief, Vectrus cited, and quoted from, various decisions by
    the United States Court of Appeals for the Federal Circuit and the United States Court of
    Federal Claims for principles of contract interpretation to support its arguments that the
    court must be restricted to the 2009 Agreement’s plain text or to “‘the intent of the parties
    at the time the agreement was made.” (emphasis original) (quoting Allen v. United
    States, 
    119 Fed. Cl. 461
    , 480 (2015) (internal quotation omitted). See Phytelligence, Inc.
    v. Wash. St. Univ., 
    973 F.3d 1354

    Cir. 1988); Oasis Int’l Waters, Inc. v. United States, 
    134 Fed. Cl. 155
    , 184 (2017)).
    Protestor further cited to a number of United States Supreme Court cases on treaty
    interpretation to argue “that the United States’ interpretation of a treaty or international
    agreement cannot trump the text of the document itself.” (citing Hamdan v. Rumsfeld, 
    548 U.S. 557
    , 630 (2006); El Al Israel Airlines, Ltd. v. Tsui Yuan Tseng, 
    525 U.S. 155

    457 U.S. 176
    , 185 (1982); Choctaw Nation of Indians v. United
    States, 
    318 U.S. 423
    , 432 (1943); Perkins v. Elg,

    , 337-39 (1939)).

    concurring in part); Nat’l Westminster Bank, PLC v. United States, 
    512 F.3d 1347
    , 1358-
    59 (Fed. Cir. 2008)). Protestor argued that Diplomatic Note No. 127 is “far removed
    temporally from the 2009 amendment,” and such removal “degrad[es] its evidentiary
    value” with respect to the meaning of the phrase “Danish/Greenlandic sources” in the
    2009 Agreement. (alteration added). Further, protestor emphasized that in interpreting
    the 2009 Agreement, “the Court must determine whether the ‘terms’ of the relevant
    ‘international agreement’ had ‘the effect of requiring’ insertion of the eligibility criteria in
    the RFP.” (emphasis in original) (quoting 
    10 U.S.C.A. § 3204
    (a)(4)). According to
    protestor, “[f]or the United States to prevail,” under the Competition in Contracting Act,
    “the AR [Administrative Record] must establish that the plain text of the amended MOU
    was susceptible to one, and only one, interpretation in 2009—that American-owned
    companies are not Danish or Greenlandic sources.” (emphasis in original; alterations
    added). Protestor argued that if the text of the 2009 Agreement is susceptible to multiple
    interpretations, then the 2009 Agreement cannot be read to “have the effect of requiring”
    the eligibility criteria at issue in the above captioned bid protest.
    Defendant in its cross-motion for judgment on the Administrative Record
    characterized “Danish/Greenlandic sources” as “an undefined term in an international
    agreement,” and argued that although the 2009 Agreement and the 1991 Memorandum
    of Understanding are “silent on the definition of ‘Danish/Greenlandic sources,’ the
    countries have subsequently defined the term.” According to defendant, Diplomatic Note
    No. 127 “memorialized a shared understanding of the term’s [Danish/Greenlandic
    source’] definition,” a shared understanding which is the result of “several years of
    discussions and negotiations,” and which “made clear that subsidiaries of foreign
    companies were not Danish/Greenlandic sources under the 1991 MOU.” (alteration
    added). According to defendant, “[t]o argue that because the clarified definition does not
    have the same legal formality as an international agreement is simply putting form over
    substance.” (alteration added). Defendant cited to the Vienna Convention on the Law of
    Treaties to argue that “[i]t is common practice for parties to an international agreement
    [to] revisit and refine their interpretation and application of an international agreement’s
    terms,” as with the 2013 diplomatic correspondence and Diplomatic Note No. 127.
    (alterations added) (citing Vienna Convention on the Law of Treaties, art. 31, May 23,
    1969, 1155 U.N.T.S. 331).52 According to defendant, therefore, the United States and
    Denmark “were free to meet and discuss clarifying the definitions so long as the countries
    acted in good faith,[53] and the resulting understanding of the term is not inconsistent with
    52  Although defendant admitted that “the United States has not ratified” the Vienna
    Convention, defendant also stated that “the United States has acknowledged that Article
    31 of the VCLT [Vienna Convention] is customary international law.” (alteration added)
    (citing RESTATEMENT (FOURTH) OF FOREIGN RELATIONS LAW § 306, cmt. a (2018)).
    53Defendant’s statement that “the countries acted in good faith” appears to be a reference
    to the Restatement of Foreign Relations Law, which states: “A treaty is to be interpreted
    in good faith in accordance with the ordinary meaning to be given to its terms in their
    97
    the 1991 MOU.” (alteration added) (citing RESTATEMENT (FOURTH) OF FOREIGN RELATIONS
    LAW § 306). Defendant further argued “that not only does the interpretation include a
    treaty’s text, but also includes, the ‘postratification understanding of signatory nations,’”
    (quoting Medellin v. Texas, 
    552 U.S. at 506
    ) and that “when a term of an international
    agreement is undefined, the courts have looked to the plain meaning and the purpose of
    the treaty of [sic] agreement.” (alteration added) (citing Fernandez v. Bailey, 
    909 F.3d 353
    (11th Cir. 2018)). Moreover, defendant argued, relying upon National Westminster Bank,
    PLC v. United States, 
    512 F.3d 1347
    , that “the United States and Denmark, with
    Greenland, memorialized their shared understanding of the meaning [sic]
    ‘Danish/Greenlandic source’ to be used in this procurement,” and that “[b]ecause the
    countries’ understanding is permitted, and indeed the United States’ engagement with
    Denmark and Greenland is squarely within the role of the Executive Branch, it should not
    be disturbed by this bid protest.” (alterations added).
    Defendant also argued that the eligibility criteria established in Diplomatic Note No.
    127 were “designed to maximize competition” and “the procuring agency balanced its
    obligations under the bilateral framework with the competition preference in the
    government procurement statutory and regulatory framework by ‘soliciting as many offers
    from as many potential sources as is practicable under the circumstances.’” (quoting FAR
    6.301(d)); see FAR 6.301(d) (“When not providing for full and open competition, the
    contracting officer shall solicit offers from as many potential sources as is practicable
    under the circumstances.”).54 Defendant referred to multiple rejected offeror eligibility
    criteria proposed by the Danish government, which would have required, for example,
    that the awardee be partially owned by the Greenlandic government or that the
    Greenlandic government receive a mandatory “share of the awarded contract.”
    Precedential cases of the United States Supreme Court and the United States
    Court of Appeals for the Federal Circuit have established general standards by which
    interpretation of treaties and international agreements occurs. The United States
    Supreme Court stated in Medellin v. Texas that “[t]he interpretation of a treaty, like the
    interpretation of a statute, begins with its text,” Medellin v. Texas, 
    552 U.S. at
    506-07
    (citing Air France v. Saks, 
    470 U.S. 392
    , 396–397 (1985)), but that “[b]ecause a treaty
    ratified by the United States is ‘an agreement among sovereign powers,’ we have also
    considered as ‘aids to its interpretation’ the negotiation and drafting history of the treaty
    as well as ‘the postratification understanding’ of signatory nations.”

    The United States Court of Appeals for the Federal Circuit succinctly summarized
    the Supreme Court’s approach to treaty interpretation in Xerox Corp. v. United States:
    In construing a treaty, the terms thereof are given their ordinary meaning in
    the context of the treaty and are interpreted, in accordance with that
    meaning, in the way that best fulfills the purposes of the treaty. See United
    States v. Stuart, 
    489 U.S. 353
    , 365–66, 
    109 S. Ct. 1183
    , 1190–91, 
    103 L. Ed. 2d 388
     (1989) (interpreting a treaty to carry out the intent or
    expectations of the signatories); Kolovrat v. Oregon, 
    366 U.S. 187
    , 193–94,
    
    81 S. Ct. 922
    , 925–26, 
    6 L. Ed. 2d 218
     (1961) (a treaty should be interpreted
    to carry out its purpose). As discussed in Sumitomo Shoji America, Inc. v.
    Avagliano, 
    457 U.S. 176
    , 185, 
    102 S. Ct. 2374
    , 2379, 
    72 L. Ed. 2d 765
    (1982), the court's role is “limited to giving effect to the intent of the Treaty
    parties.” See generally Restatement (Third) of Foreign Relations Law of the
    United States, Part III, Introductory Note at 144–145 (1987). The judicial
    obligation is to satisfy the intention of both of the signatory parties, in
    construing the terms of a treaty. Valentine v. United States, 
    299 U.S. 5
    , 11,
    
    57 S. Ct. 100
    , 103, 
    81 L. Ed. 5
     (1936) (“it is our duty to interpret [the treaty]
    according to its terms. These must be fairly construed, but we cannot add
    or detract from them.”).
    Unless the treaty terms are unclear on their face, or unclear as applied to
    the situation that has arisen, it should rarely be necessary to rely on extrinsic
    evidence in order to construe a treaty, for it is rarely possible to reconstruct
    all of the considerations and compromises that led the signatories to the
    100
    final document. However, extrinsic material is often helpful in understanding
    the treaty and its purposes, thus providing an enlightened framework for
    reviewing its terms. See Air France v. Saks, 
    470 U.S. 392
    , 400, 
    105 S. Ct. 1338
    , 1343, 
    84 L. Ed. 2d 289
     (1985) (“In interpreting a treaty it is proper, of
    course, to refer to the records of its drafting and negotiation.”) However, “the
    ultimate question remains what was intended when the language actually
    employed . . . was chosen, imperfect as that language may be.” Great–West
    Life Assurance Co. v. United States, 
    678 F.2d 180
    , 188, 
    230 Ct. Cl. 477
    (1982).

    When interpreting a treaty or international agreement to give effect to the intent or
    purpose thereof, the United States Supreme Court has historically consulted the
    diplomatic correspondence of the signatory governments as well as other evidence of
    those governments’ practical construction of the treaty or international agreement’s
    language. See, e.g., David J. Bederman, Medellín's New Paradigm for Treaty
    Interpretation, 102 AM. J. INT’L L. 529, 536 (2008) (discussing a “broad set of materials
    that the Supreme Court has now consistently endorsed as a legitimate source for the
    extrinsic interpretation of treaties” which “revolve around the expectations of the U.S.
    treaty partners, as reflected both in ‘the negotiation and drafting history of the treaty’ and
    in ‘the postratification understanding of signatory nations’” (footnotes omitted) (quoting
    Medellin v. Texas, 
    552 U.S. at 507
     (internal quotations omitted))); 
    id. at 537
     (explaining
    with respect to “postratification understandings” that “[w]hen the Court has found a treaty

    construction of it,’” (second alteration and ellipses in original; footnote omitted) (quoting
    Nielsen v. Johnson, 
    279 U.S. 47
    , 52 (1929))), which “has led the Court to consider

    , 147-48 (1850))); Robert M. Chesney, Disaggregating Deference: The Judicial Power
    and Executive Treaty Interpretations, 92 IOWA L. REV. 1723, 1743-44 (2007) (discussing
    the Supreme Court’s reliance on diplomatic correspondence in Nielsen in the context of
    the evolution of deference to executive interpretations of treaties). Research reveals a
    line of cases in which the Supreme Court specifically has relied on diplomatic
    correspondence or the public acts of signatory governments to a treaty to aid the Supreme
    Court’s interpretation of the treaty’s language, as early as in the United States Supreme
    Court’s opinion in United States v. Reynes, 
    50 U.S. (9 How.) 127
     (1850), in which the
    public acts of a signatory government were considered. The Reynes decision concerned
    the interpretation of two treaties, the Treaty of St. Ildefonso of 1800, between the Kingdom
    of Spain and the French Republic, and the Treaty of Paris of 1803, between the French
    Republic and the United States, regarding the grant of certain land within territory which
    had passed first from Spain to France, and later from France to the United States in the
    101
    Louisiana Purchase. See id. at 144-45. When considering the validity of a land grant by
    a Spanish official, the Supreme Court phrased the “inquiry” in the case as “whether the
    grant in question was protected either by the treaty of retrocession from Spain to the
    French Republic, or by the treaty of Paris, by which the Territory of Louisiana was ceded
    to the United States.” Id. at 147. The Supreme Court explained:
    The treaties above mentioned, the public acts and proclamations of the
    Spanish and French governments, and those of their publicly recognized
    agents, in carrying into effect those treaties, though not made exhibits in
    this cause, are historical and notorious facts, of which the court can take
    regular judicial notice; and reference to which is implied in the investigation
    before us.
    Id. at 147-48. The Supreme Court further explained that “[i]n the construction of treaties,
    the same rules which govern other compacts properly apply.” Id. at 148 (alteration added).
    The Supreme Court noted, with respect to the transfer from Spain to France, “that there
    is not in this treaty a single stipulation or guarantee in favor of the lives or the property of
    the subjects or inhabitants of the ceded country, much less a reservation of power to grant
    or invest new rights within that territory.” Id. at 149. The Supreme Court further observed
    that “[t]he same characteristic is observable in the royal order announcing the cession,
    and also in the formal act of delivery of the territory.” Id. (alteration added). The Supreme
    Court proceeded to examine the order issued by the King of Spain as a means to interpret
    the Treaty of St. Ildefonso. The Supreme Court noted that
    the language of his Catholic Majesty may correctly be understood as
    conveying an acknowledgment that he had made no condition or stipulation
    whatever in behalf of his late subjects, and had no power to insist on any
    thing of the kind; but had handed them over to the justice or the liberality of
    the new government to whom he had transferred them.
    Id. Moreover, the Supreme Court characterized the King of Spain’s order as
    an explicit admission of what the treaty itself exposes; namely, that no
    special stipulation had been made for the protection either of persons or
    property; that he regarded his own authority and the dominion of Spain over
    the territory as at an end, and that his sole reliance for the protection and
    welfare of his late subjects, and even for enforcing the grants he himself,
    through his officials, had made to them, was on the justice and benevolence
    of the new government.
    Id. at 150. The Supreme Court was ultimately unable to determine whether the grant
    claimed by the petitioner in Reynes had remained valid, because after consideration of
    the later Treaty of Paris, the Supreme Court determined that the question at issue was
    whether “the territory south of the thirty degree [sic] of north latitude, and lying between
    the Mississippi and Perdido, was ceded to the United States,” and with respect to that
    question the Supreme Court acknowledged “[t]he legislative and executive departments
    102
    of the government had determined that the entire territory was so ceded,” as well as “that
    the propriety of their determination it was not within the province of the judiciary to
    contravene or question.” Id. at 153-54 (alterations added).
    The United States Supreme Court expressly discussed the impact of diplomatic
    correspondence in United States v. Texas, 
    162 U.S. 1
     (1896), a case which concerned
    the interpretation “of the treaty between the United States and Spain made February 22,
    1819,” as well as a subsequent “treaty of 1828 betwee [sic] the United States of America
    and the United Mexican States,” which reaffirmed the boundaries set by the 1819 treaty,
    to determine whether Texas or the federal government held title to certain land. See 
    id. at 23, 29
     (alteration added). The Supreme Court explained: “Before examining those
    articles [of the treaty of 1819], it will be useful to refer to the diplomatic correspondence
    that preceded the making of the treaty.” 
    Id. at 23
     (alteration added). The Supreme Court
    considered diplomatic exchanges between the governments of the United States and
    Spain, reflecting the two governments’ efforts to agree on which rivers, parallels, and
    meridians would form the boundary of the anticipated territorial cession to the United
    States. See 
    id. at 23-27
    . The Supreme Court stated:
    We have alluded to this diplomatic correspondence to show the
    circumstances under which the treaty of 1819 was made, and to bring out
    distinctly two facts that are of some importance in the present discussion:
    (1) That the negotiators had access to the map of Melish, improved to 1818,
    and published at Philadelphia. (2) That the river referred to in the
    correspondence as “Red River” was believed by the negotiators to have its
    source near Santa Fé and the Snow Mountains.
    
    Id. at 27
     (alteration added). In relevant part, the United States and Texas disputed
    whether the 100th meridian, as it incorrectly appeared on a map, referred to as the Melish
    map, consulted by the United States and Spain during negotiations leading to the 1819
    treaty, or whether the 100th meridian, as it was in actuality, formed a portion of the
    applicable boundary of the territory at issue. See 
    id. at 34-36
    . Moreover, the Melish map
    was referenced in the text of the 1819 treaty, following a description of metes and bounds
    of territory to be ceded by Spain: “The whole being as laid down in Melish’s map of the
    United States, published at Philadelphia, improved to the first of January, 1818.” See 
    id. at 27-28
    . The Supreme Court explained:
    Undoubtedly, the intention of the two governments, as gathered from the
    words of the treaty, must control, and the entire instrument must be
    examined in order that the real intention of the contracting parties may be
    ascertained. 1 Kent, Comm. 174. For that purpose the map to which the
    contracting parties referred is to be given the same effect as if it had been
    expressly made a part of the treaty.
    United States v. Texas, 
    162 U.S. at
    36-37 (citing Jefferis v. E. Omaha Land Co., 
    134 U.S. 178
    , 194 (1890); Cragin v. Powell, 
    128 U.S. 691
    , 696 (1888); Noonan v. Lee, 
    67 U.S. (2 Black) 499
     (1862), overruled by Hornbuckle v. Toombs, 
    85 U.S. (18 Wall.) 648
     (1873);
    103
    McIver’s Lessee v. Walker, 17 U.S (4 Wheat.) 444 (1819)). The Supreme Court in United
    States v. Texas further asked,
    are we justified, upon any fair interpretation of the treaty, in assuming that
    the parties regarded that map as absolutely correct in all respects, and not
    to be departed from in any particular, or under any circumstances? Did the
    contracting parties intend the words of the treaty should be literally followed,
    if by so doing the real object they had in mind would be defeated?
    Id. at 37. Moreover, the Supreme Court explained, “[s]o far as is disclosed by the
    diplomatic correspondence that preceded the treaty, the negotiators assumed, for the
    purposes of a settlement of their controversy, that Melish’s map was, in the main, correct.
    But they did not and could not know that it was accurate in all respects.” Id. at 38
    (alteration added). Therefore, according to the Supreme Court, “[w]hile the line agreed
    upon was, speaking generally, to be as laid down on Melish's map, it was to be fixed with
    more precision, and designated with more exactness, by representatives of the two
    nations.” Id. (alteration added). The Supreme Court concluded “that the treaty itself, upon
    a reasonable interpretation of its provisions, left it open to the contracting parties, through
    commissioners and surveyors, to fix the lines with precision, and therefore to show by
    competent evidence where the true 100th meridian was located.” Id. at 42.
    The United States Supreme Court, in the case of Terrace v. 
    Thompson, 263
     U.S.
    197 (1923), considered diplomatic correspondence when determining whether a
    Washington state statute restricting foreign ownership of land conflicted with a “treaty
    between the United States and Japan,” which indicated “that it was entered into for the
    purpose of establishing the rules to govern commercial intercourse between the
    countries.” See id. at 211, 222. While the Supreme Court stated that “[a] careful reading
    of the treaty suffices in our opinion to negative the claim asserted by appellant that it
    conflicts with the state act,” the Supreme Court also explained that “if the language left
    the meaning of its provisions doubtful or obscure, the circumstances of the making of the
    treaty,” including diplomatic correspondence, “would resolve all doubts against the
    appellants’ contention.” Id. at 223 (alteration added). In particular, the Supreme Court
    observed, “[t]he letter of Secretary of State Bryan to Viscount Chinda, July 16, 1913,
    shows that, in accordance with the desire of Japan, the right to own land [in the United
    States] was not conferred.” Id. (alterations added).
    The United States Supreme Court also made use of diplomatic correspondence to
    interpret a treaty in the case of Nielsen v. Johnson, 
    279 U.S. 47
    . The Nielsen case
    concerned a potential conflict between Iowa inheritance taxes, which imposed a higher
    tax on “alien nonresidents of the United States,” and “article 7 of the Treaty of April 26,
    1826, between the United States and Denmark,” which forbade the imposition of “higher
    or other duties, charges, or taxes” on citizens of one signatory country by the other. See
    
    id. at 49-50
    . The Supreme Court explained that “[w]hen their [treaties’] meaning is
    uncertain, recourse may be had to the negotiations and diplomatic correspondence of the
    contracting parties relating to the subject-matter and to their own practical construction of
    it.” 
    Id. at 52
     (alterations added) (citing Terrace v. 
    Thompson, 263
     U.S. at 223; United
    104
    States v. Texas, 
    162 U.S. at 23
    ; Kinkead v. United States, 
    150 U.S. 483
    , 486 (1893); In
    re Ross, 
    140 U.S. at 467
    ). The Supreme Court in Nielsen surveyed the diplomatic
    “note[s]” and “communication[s]” between the United States and Denmark from 1824 to
    1826 relating to the 1826 treaty, including a “communication” sent after the treaty had
    been ratified. See id. at 52-57 (alterations added). The Supreme Court determined that
    The history of article 7 and references to its provisions in displomatic [sic]
    exchanges between the United States and Denmark leave little doubt that
    its purpose was both to relieve the citizens of each country from onerous
    taxes upon their property within the other and to enable them to dispose of
    such property, paying only such duties as are exacted of the inhabitants of
    the place of its situs, as suggested by this court in Petersen v. Iowa, supra,
    
    245 U. S. 174
    , 
    38 S. Ct. 109
    , 
    62 L. Ed. 225
     [(1917)], and also to extend like
    protection to alien heirs of the noncitizen.
    Nielsen v. Johnson, 
    279 U.S. at 52
     (alterations added). The Supreme Court in Nielsen
    held “[t]hat it was the purpose of the high contracting parties to prohibit discriminatory
    taxes of this nature clearly appears from the diplomatic correspondence preceding and
    subsequent to the execution of the treaty,” and that, while the 1826 treaty did not refer
    specifically to inheritance taxes, “the language of article 7, interpreted with that liberality
    demanded for treaty provisions, sufficiently expresses this purpose.” 
    Id. at 57
     (alteration
    added). Therefore, the Supreme Court explained, “[i]n the light of the avowed purpose of
    the Treaty to forbid discriminatory taxes of this character, and its use of language
    historically deemed to embrace them, such effect should be given to its provisions,” and
    the Supreme Court invalidated the tax at issue for violating the treaty. 
    Id. at 58
     (alteration
    added).
    In the case of Todok v. Union State Bank of Harvard, Nebraska, 
    281 U.S. 449
    (1930), the United States Supreme Court considered “article 6 of the treaty with Sweden
    of April 3, 1783,” which was applicable because it had been “revived by the treaty with
    Sweden and Norway of Sept. 4, 1816,” then later “replaced by the treaty with Sweden
    and Norway of July 4, 1827,” which was “now in force with Norway,” to determine if the
    treaty’s provision for free disposition of “goods and effects” overrode Nebraska law with
    respect to the conveyance of land as a homestead to a Norwegian citizen. See 
    id.
     at 452-
    53. The Supreme Court explained that, as the original text of the treaty was in French,
    “the French text is therefore controlling” and that “[t]he phrase ‘goods and effects' is a
    translation of the French expression ‘fonds et biens.’ The French word ‘biens' has a wider
    significance than the English word ‘goods' (used by the American translator) and
    embraces real property.” 
    Id. at 454
     (alteration added). The Supreme Court further
    explained that
    [i]n a note addressed by the Swedish Minister at Washington to the
    Department of State under date of December 12, 1910, in response to an
    inquiry by the Secretary of State of the United States, the Swedish Minister
    stated his understanding that the authorities in Sweden had always held
    105
    that the words ‘goods and effects' in article 6 of the treaty of 1783 include
    real estate.
    
    Id.
     (alteration added). According to the Supreme Court, the understanding of the Swedish
    Minister “is the correct construction of the article of the treaty, applying the fundamental
    principle that treaties should receive a liberal interpretation to give effect to their apparent
    purpose.” 
    Id.
     The Supreme Court held, however, that while the treaty provided for free
    disposition of real property, “the treaty did not invalidate the provisions of the Nebraska
    statute,” because the Nebraska statute concerned only the special rules regarding holding
    property as a homestead and was not a restriction on the transfer of property generally.

    id. at 456

    In Cook v. United States, 
    288 U.S. 102
    , which concerned “the Treaty between the
    United States and Great Britain proclaimed May 22, 1924,” relating to the seizure of British
    ships by the United States Coast Guard, 
    id. at 109
    , the United States Supreme Court
    explained that “[i]n construing the Treaty its history should be consulted.” 
    Id. at 110
    (alteration added) (citing Nielsen v. Johnson, 
    279 U.S. at 52
    ; Oklahoma v. Texas, 
    260 U.S. 606
     (1923); United States v. Texas, 
    162 U.S. 1
    ). The Supreme Court in Cook held
    that
    [t]he history reveals that serious differences had arisenbetween [sic] the two
    governments in that connection [with laws enforcing Prohibition]; and that,
    for the purpose of resolving them, the parties determined to deal completely
    with the subject of search and seizure, beyond our territorial limits, of British
    vessels suspected of smuggling liquors.
    
    Id.
     (alterations added). The Supreme Court considered the history of the seizure of British
    vessels carrying alcohol in American territorial waters during the first years of Prohibition
    and the British government’s communicated objections to such seizures. See 
    id.
     at 112-
    18 (collecting cases and statements with respect to seizures). The Supreme Court
    referred to “note[s]” between diplomatic officials, to “repl[ies]” to “question[s]” from the
    opposite government, to “statement[s] of the American position,” and to “letter[s]” and
    other communications from the British government, which documented the British
    government’s objections and diplomatic efforts to address them. See 
    id.
     at 112-15 n.6-7,
    n.10-15 (alterations added). In light of this history, the Supreme Court interpreted the
    1924 treaty along with the federal statutes in effect at the time, and determined that,
    consistent with the intent to resolve diplomatic tensions with the British government, the
    1924 treaty had deprived the United States government of jurisdiction to seize the ship at
    issue in Cook. See 
    id. at 118-21
    .
    The United States Supreme Court’s decision in Factor v. Laubenheimer, 
    290 U.S. 276
     (1933), concerned the interpretation of “[t]he extradition provisions of the treaty with
    Great Britain of 1842,” which were consulted in order to interpret a later “supplemental
    convention of 1889.” 
    Id. at 287, 288
     (alteration added). The Supreme Court explained,
    following the example of Nielsen, that “[i]n ascertaining the meaning of a treaty we may
    look beyond its written words to the negotiations and diplomatic correspondence of the
    106
    contracting parties relating to the subject-matter, and to their own practical construction
    of it.” 
    Id. at 294-95
     (alteration added) (citing Nielsen v. Johnson, 
    279 U.S. at 52
    ; Terrace
    v. 
    Thompson, 263
     U.S. at 223; United States v. Texas, 
    162 U.S. at 23

    States, 
    150 U.S. at 486
    ; In re Ross, 
    140 U.S. at 467
    ). The Supreme Court in Factor
    observed that “[f]rom the ensuing diplomatic correspondence [after the treaty of 1842] it
    clearly appears that this government [the United States] then asserted that the Treaty of
    1842 obligated both parties to surrender fugitives duly charged,” and that the United
    States
    government does not appear to have receded from that position, and while
    the British government has never definitely yielded to it, except in so far as
    the arguments addressed to us in behalf of the respondent may be taken to
    have that effect, that fact or even the failure of Great Britain to comply with
    the obligations of the treaty would not be ground for refusal by this
    government to honor them or by this Court to apply them.
    Id. at 295-98 (alterations added). Subsequently, in Choctaw Nation of Indians v. United
    States, 
    318 U.S. 423
    , the United States Supreme Court, relying on the Factor and Cook
    cases, wrote, “[o]f course treaties are construed more liberally than private agreements,
    and to ascertain their meaning we may look beyond the written words to the history of the
    treaty, the negotiations, and the practical construction adopted by the parties.” 
    Id.

    32 (citing Factor v. Laubenheimer, 
    290 U.S. at 294-95

    288 U.S. at 112
    )); see also Medellin v. Texas,

    The United States Supreme Court’s guidance that the signatory countries’
    diplomatic correspondence, subsequent understanding, and “practical construction” of
    the intent of the language of treaties may be used to determine the treaty’s meaning has
    continued to be applied by the Supreme Court. See Trans World Airlines, Inc. v. Franklin
    Mint Corp., 
    466 U.S. at 259-60
     (“In determining whether the Executive Branch’s domestic
    implementation of the Convention is consistent with the Convention’s terms, our task is
    to construe a ‘contract’ among nations. The conduct of the contracting parties in
    implementing that contract in the first 50 years of its operation cannot be ignored.”). In the
    case of Sumitomo Shoji America, Inc. v. Avagliano, 
    457 U.S. 176
    , for example, the United
    States Supreme Court interpreted “the Friendship, Commerce and Navigation Treaty
    between Japan and the United States,” to determine whether Sumitomo Shoji America,
    a subsidiary of a Japanese company operating in America, was itself a Japanese
    company under the terms of the treaty. See 
    id. at 180
    . The Supreme Court first considered
    “the literal language” of the treaty to hold that Sumitomo Shoji America was “a company
    of the United States operating in the United States,” and not a Japanese company. See
    
    id. at 182-83
    . The Supreme Court further explained:
    The Governments of Japan and the United States support this interpretation
    of the Treaty. Both the Ministry of Foreign Affairs of Japan and the United
    States Department of State agree that a United States corporation, even
    107
    when wholly owned by a Japanese company, is not a company of Japan
    under the Treaty and is therefore not covered by Article VIII(1). The Ministry
    of Foreign Affairs stated its position to the American Embassy in Tokyo with
    reference to this case:
    “The Ministry of Foreign Affairs, as the Office of [the Government of
    Japan] responsible for the interpretation of the [Friendship,
    Commerce and Navigation] Treaty, reiterates its view concerning the
    application of Article 8, Paragraph 1 of the Treaty: For the purpose
    of the Treaty, companies constituted under the applicable laws . . .
    of either Party shall be deemed companies thereof and, therefore, a
    subsidiary of a Japanese company which is incorporated under the
    laws of New York is not covered by Article 8 Paragraph 1 when it
    operates in the United States.”
    The United States Department of State also maintains that Article VIII(1)
    rights do not apply to locally incorporated subsidiaries.
    
    Id. at 183-84
     (alterations and ellipsis in original; footnotes omitted). In a footnote, the
    Supreme Court in Sumitomo attributed the Japanese Ministry of Foreign Affairs’ quoted
    interpretation of the treaty to a “cable from the United States Embassy in Tokyo to the
    Secretary of State relaying the position of the Ministry of Foreign Affairs of Japan,” dated
    February 26, 1982, and the Supreme Court explained that “[t]he Government of Japan
    reconfirms its view” of the proper interpretation of the treaty in another diplomatic
    communication, dated April 21, 1982. See 
    id.
     at 184 n.9.
    More recently, courts have continued to rely upon diplomatic correspondence and
    other indications by the signatory governments of how to approach the interpretation of
    treaties. See Coplin v. United States, 
    6 Cl. Ct. 115
     (1984), rev’d, 
    761 F.2d 688
     (Fed. Cir.
    1985) (reversing the United States Claims Court’s decision interpreting an agreement
    between the United States and Panama on the basis of a newly-produced diplomatic note
    from Panama), aff’d on other grounds sub nom., O’Connor v. United States, 
    479 U.S. 27
    (1986). The Coplin cases concerned the Panama Canal Treaty, between the Republic of
    Panama and the United States, signed in 1977 and ratified by the United States Senate,
    as well as the associated Agreement in Implementation of Article III of the Panama Canal
    Treaty, referred to by the court as the “Implementation Agreement,” see Coplin v. United
    States, 6 Cl. Ct. at 119, which had been negotiated simultaneously with Panama Canal
    Treaty and signed by the President of the United States, but not referred for ratification
    by the Senate. See Coplin v. United States, 
    761 F.2d at 689-90
    , aff’d on other grounds
    sub nom., O’Connor v. United States, 
    479 U.S. 27
     (1986). In particular, as the United
    States Claims Court’s decision explained, at issue was whether United States
    government employees of the Panama Canal Commission were exempted from United
    States income taxes by virtue of language in the Implementation Agreement which read:
    “United States citizen employees and dependents shall be exempt from any taxes, fees,
    or other charges on income received as a result of their work for the Commission.” Coplin
    v. United States, 6 Cl. Ct. at 120 (emphasis in original). The Claims Court in Coplin
    interpreted the Implementation Agreement’s language, noting “that Article XV, according
    108
    to its heading, purports to deal with the general subject of taxation, that two of its
    paragraphs specifically refer to the imposition of taxes by Panama only, and that the
    parties were careful elsewhere in the treaty to specify the taxing authority being
    addressed” by the Implementation Agreement. Id. at 127. The Claims Court in Coplin held
    that “a fair reading of the language in question leads to the conclusion that it [the
    Implementation Agreement language] unambiguously exempts U.S. citizens who are
    Commission employees from taxation by Panama as well as the United States.” Id.
    The Claims Court decision in Coplin further noted, when considering the
    negotiation history of the Implementation Agreement, that “there is no evidence
    whatsoever as to the interpretation given this language by Panama.” See id. at 128
    (emphasis in original). The Claims Court focused its analysis on the intentions of the
    governments as represented by the language of the Implementation Agreement, stating
    that “[t]he language finally adopted reflected the position of neither party” with respect to
    “the sensitive sovereignty issue” of which government would tax the Panama Canal
    Commission’s employees, but also that “[w]ithout a statement from Panama, it is of
    course difficult to be certain as to what its motivations might have been in accepting this
    language.” Id. at 133 (alterations added). The Claims Court in Coplin held that the
    language of the Implementation Agreement was unambiguous, and, further, that even if
    the language were ambiguous, that deference was not due to what the Claims Court
    understood as the United States’, but not Panama’s, interpretation of the language. See
    id. at 149.
    A panel of five judges of the United States Court of Appeals for the Federal Circuit
    heard the appeal from the Claims Court’s Coplin decision and other consolidated cases
    raising the same issue of treaty interpretation to seek a “refund of federal income taxes.”
    Coplin v. United States, 
    761 F.2d at 689
    . The Federal Circuit, recounting that the Claims
    Court had based its decision on the fact that there was “‘no evidence whatsoever as to
    the interpretation given this language by Panama,’” 
    id. at 691
     (quoting Coplin v. United
    States, 6 Cl. Ct. at 128, 145-47, 149 (emphasis in original)), reversed the Claims Court’s
    holding on the basis of a “diplomatic note” which postdated the Implementation
    Agreement by eight years, “‘from the Panamanian Foreign Minister in which he confirmed
    that the Panamanian Foreign Ministry shared the United States’ view that the
    Implementing Agreement was not intended to affect United States taxation of
    Commission employees.’” Id. The Panamanian diplomatic note was provided to the
    Federal Circuit panel on the day of oral argument on appeal, and, moreover, the
    Panamanian diplomatic note had not existed when the Claims Court had heard the case.
    See id. The diplomatic note from the Panamanian government “enclosed letters from the
    Panamanian team that negotiated the Implementation Agreement,” which stated “that the
    ‘provisions resulted from negotiations that did not deal with the United States[’] authority
    to tax the individuals mentioned therein.’” Id. (alteration in original). When discussing
    whether to consider the diplomatic note from the Panamanian government, the Federal
    Circuit in Coplin recognized an “exception” to “[t]he general rule” against “supplementing
    the record with new evidence” on appeal. See id. at 691. The Federal Circuit reviewed
    relevant precedent and explained:
    109
    Reversing the judgment of a lower court on the question whether the validity
    of a grant of land was protected by certain treaties, the Supreme Court
    examined diplomatic records outside the record and held that “the public
    acts and proclamations of [foreign] governments, and those of their publicly
    recognized agents, in carrying into effect those treaties, though not made
    exhibits in this cause, are historical and notorious facts, of which the court
    can take regular judicial notice.” United States v. Reynes, 
    50 U.S. (9 How.) 127
    , 147–48, 
    13 L. Ed. 74
     (1850); see generally Jones v. United States,
    
    137 U.S. 202
    , 214–16, 
    11 S. Ct. 80
    , 84–85, 
    34 L. Ed. 691
     (1890). In
    construing an extradition treaty the Court directed counsel's attention to
    matter outside the record and invited counsel to conduct a further search
    through “available diplomatic records and correspondence” in preparation
    for reargument of the case. Factor v. Laubenheimer, 
    290 U.S. 276
    , 295, 
    54 S. Ct. 191
    , 196, 
    78 L. Ed. 315
     (1933). Nor is our consideration of the cable
    barred because it was not “available” when the record closed in the lower
    court. In determining the proper interpretation of a treaty provision, the
    Supreme Court relied on expressions of intent in diplomatic
    correspondence dated more than a year after the appellate court decision
    and within a few days of argument before the Court itself. Sumitomo Shoji
    America, Inc. v. Avagliano, 
    457 U.S. 176
    , 184 n. 9, 
    102 S. Ct. 2374
    , 2379
    n. 9, 
    72 L. Ed. 2d 765
     (1982).
    Coplin v. United States, 
    761 F.2d at 691
     (alteration in original). On the basis of the newly
    produced diplomatic note in the Coplin case, the Federal Circuit held, because “[t]he
    court’s ‘role is limited to giving effect to the intent of the treaty parties,’” 
    id.
     (quoting
    Sumitomo Shoji Am., Inc. v. Avagliano, 
    457 U.S. at 185
    ), that “the record now reveals the
    intent of each government” such that “both treaty parties agree that paragraph 2 was not
    intended to create an exemption from United States domestic taxation,” and for this
    reason the Federal Circuit in Coplin reversed the decision of the Claims Court. Id. at 692.
    Three of the five members of the Federal Circuit panel in Coplin signed onto a brief
    concurring opinion55 which agreed with “the result of the majority decision” and stated that
    “[a] complete reading of the record, the treaty and the Implementation Agreement leads
    me to conclude that Article XV had no relevance to taxation by the United States of its
    own citizens.” Id. (Nies, J., concurring) (alteration added). Regarding the diplomatic note
    relied on by the majority, the concurrence stated: “With respect to the late filed
    concurrence by the Panamanian government with the interpretation by the U.S. State
    55 The author of the majority opinion in the Federal Circuit’s Coplin decision also filed a
    separate opinion expressing “Additional Views,” in which the author, joined by the
    remaining circuit judge who was not in the three judge concurrence, stated that “[w]hile it
    is proper for this court to take judicial notice of the new evidence, introducing it hours
    before oral argument is certainly not something I want to encourage,” and that “[u]nder
    these circumstances, to require the taxpayers to bear even their own costs borders on
    the unconscionable. Therefore, I would have the government pay the taxpayers’ costs.”

    Department, that evidence was not necessary to the above decisions and is not
    necessary here. It merely confirms the most reasonable interpretation of the Article.” 
    Id.
    (Nies, J., concurring). The concurrence provided no further analysis of the Panamanian
    diplomatic note.
    Protestor in the above captioned bid protest argued that “a majority (three of the
    five judges) on the panel [of the Federal Circuit in Coplin] expressly limited their
    concurrence with reversing the lower court’s ruling to their interpretation of the plain text,”
    and protestor claimed that “the majority’s concurrence rejected consideration of ‘the late
    filed concurrence by the Panamanian government with the interpretation by the U.S. State
    Department’ as ‘not necessary’ to the ruling because it ‘merely confirms the most
    reasonable interpretation of the Article.’” (alteration added) (quoting Coplin v. United
    States, 
    761 F.2d at 692
     (Nies, J., concurring)).
    The United States Supreme Court granted certiorari to the Federal Circuit’s
    decision in Coplin and affirmed the Federal Circuit on other grounds under the name
    O’Connor v. United States, 
    479 U.S. 27
     (1986), but did not challenge the language and
    conclusion of the Federal Circuit on the issues relevant to the case now before this court.
    The Supreme Court’s opinion in O’Connor analyzed the text of the Agreement in
    Implementation of Article III of the Panama Canal Treaty, comparing the language of
    different articles and sections of the Implementation Agreement. See 
    id. at 30
    . The
    Supreme Court held in O’Connor, while “[t]here is some purely textual evidence, albeit
    subtle, of the understanding that Article XV applies only to Panamanian taxes,” that
    “[m]ore persuasive than the textual evidence, and in our view overwhelmingly convincing,
    is the contextual case for limiting Article XV to Panamanian taxes.” 
    Id. at 31
     (alterations
    added). The Supreme Court in O’Connor further held that a reading of the Implementation
    Agreement which exempted the employees from United States taxation “is utterly
    implausible and has no foundation in the negotiations leading to the Agreement.” See 
    id.
    The Supreme Court acknowledged that “limitation of Article XV to Panamanian taxes”
    was “in accord with the consistent application of the Agreement by the Executive
    Branch—a factor which alone is entitled to great weight,” 
    id.
     at 33 (citing Sumitomo Shoji
    Am., Inc. v. Avagliano, 
    457 U.S. at 184-85
    ), and “that application has gone unchallenged
    by Panama,” such that “the Panama Canal Commission consistently withheld United
    States income taxes from petitioners and others similarly situated,” while “Panama, which
    had four of its own nationals on the Board of the Commission, did not object.” 
    Id.
     The
    Supreme Court in O’Connor explained that “[t]he course of conduct of parties to an
    international agreement, like the course of conduct of parties to any contract, is evidence
    of its meaning.” 
    Id.
     (alteration added) (citing Trans World Airlines, Inc. v. Franklin Mint
    Corp., 
    466 U.S. at 259-60
    ; Pigeon River Imp., Slide & Boom Co. v. Charles W. Cox, Ltd.,
    
    291 U.S. at 158-61
    ). Moreover, the Supreme Court in O’Connor stated that the petitioner
    employees “point to no Panamanian negotiating proposal supporting” the employees’
    interpretation that they were exempt from United States income tax, “which seems to us
    not inordinately credible on its face.” Id. at 35. In a footnote to its decision in O’Connor,
    the Supreme Court addressed the Panamanian diplomatic note and described the parties’
    views of the note, but the Supreme Court concluded, “[s]ince we would sustain the
    111
    Government’s position without reference to the note, we need not resolve these disputes.”
    See id. at 33 n.2 (alteration added).
    In its supplemental brief in the protest currently before this court, Vectrus argued,
    citing O’Connor v. United States, 
    479 U.S. at 31
    , that the Supreme Court “refused to treat
    the diplomatic note from the Government of Panama as dispositive,” and instead “agreed
    with the concurrence of three of the five panel members of the Federal Circuit that it need
    not consider the diplomatic note,” which protestor characterizes as a “refusal to discuss
    the recent diplomatic note,” in favor of addressing “the perspective of the parties’
    purposes as they initially negotiated the agreement.” (emphasis in original) (citing
    O’Connor v. United States, 479 U.S at 31, 33 n.2). Defendant responded that in O’Connor,
    “the United States Supreme Court found persuasive the conduct of the nations,” citing
    O’Connor v. United States, 
    479 U.S. at 33-34
    , which defendant argued the court should
    do in the above captioned bid protest.
    While protestor characterized the Federal Circuit’s concurring opinion in Coplin as
    having “expressly rejected consideration of the Panamanian note,” the concurrence did
    not do so, only stating that the Panamanian diplomatic note was “not necessary” and that
    the diplomatic note “merely confirms the most reasonable interpretation of the Article” of
    the Implementation Agreement under consideration. See Coplin v. United States, 
    761 F.2d at 692
     (Nies, J., concurring). Moreover, the Supreme Court in O’Connor did not
    disapprove of the Federal Circuit’s consideration of the diplomatic note or indicate that
    the consideration of recent diplomatic correspondence to interpret the Implementation
    Agreement would be improper. See O’Connor v. United States, 
    479 U.S. at
    33 n.2. In
    fact, contrary to protestor’s overstatement, the Supreme Court in O’Connor indicated it
    “would sustain the Government’s position without reference to the note” from the
    Panamanian government. See 
    id.
     (capitalization in original).
    In considering the cases discussed above, there appears to be a willingness and
    pattern in complex cases to refer to relevant diplomatic correspondence of signatory
    governments to treaties and international agreements, as well as to both practical
    constructions and later courses of conduct of the signatory parties to understand treaties
    and interpret the original intent. Cf. Sumitomo Shoji Am., Inc. v. United States, 
    457 U.S. at 183-85
    ; Factor v. Laubenheimer, 
    290 U.S. at 294-95
    ; Nielsen v. Johnson, 
    279 U.S. at 52
    . Moreover, the Federal Circuit’s decision in Coplin relied for its consideration of the
    diplomatic note on United States v. Reynes, the oldest case cited above in which the
    Supreme Court relied on the public acts of a signatory government to interpret a treaty,
    as well as Factor v. Laubenheimer and Sumitomo Shoji America, Inc. v. Avagliano. See
    Coplin v. United States, 
    761 F.2d at
    691 (citing Sumitomo Shoji Am., Inc. v. Avagliano,

    290 U.S. at 295
    ; United States v. Reynes,
    50 U.S. (9 How.) at 147-48).
    The Federal Circuit’s majority opinion in Coplin was later cited by a Judge of the
    Court of Federal Claims in McManus v. United States, 
    130 Fed. Cl. 613
    , 620-21 (2017),

    plaintiff in McManus argued that his taxation violates a treaty between the United States
    and Ireland on the grounds that the plaintiff “was a ‘resident’ of Ireland,” or because “the
    United States tax on gambling winnings violates the Tax Treaty’s nondiscrimination
    provisions, which Mr. McManus argues apply to nationals of the United States and Ireland
    regardless of residence status under the Tax Treaty.” See 
    id.
     The Judge in McManus
    interpreted the Tax Treaty and cited the Federal Circuit’s majority opinion in Coplin for the
    proposition that “[t]he Supreme Court and the Federal Circuit have also ‘relied on
    expressions of intent in diplomatic correspondence’ that reveal the intent of the treaty
    parties.” 
    Id. at 620-21
     (alteration added) (quoting Coplin v. United States, 
    761 F.2d at 691-92
    ). The Judge in McManus explained that the Tax Treaty’s terms “must be read in
    context and ‘consistent with the shared expectations’ and intent of the treaty parties.” Id.
    at 623 (quoting Lozano v. Montoya Alvarez, 
    572 U.S. at 10-12
    ; citing Coplin v. United
    States, 
    761 F.2d at 691-92
    ). The Judge in McManus further explained that “[t]he court
    must look to the shared understanding of the treaty parties when construing a tax treaty.”
    See id. at 624 (alteration added) (citing Lozano v. Montoya Alvarez, 
    572 U.S. at 10-12
    ;
    Coplin v. United States, 
    761 F.2d at 691-92
    ). With respect to the question of whether the
    plaintiff in McManus qualified as an Irish resident under the terms of the Tax Treaty, the
    Judge of the Court of Federal Claims observed that “the IRS [Internal Revenue Service]
    requested assistance from Ireland Revenue” after the treaty had been executed, and the
    IRS relied on Ireland Revenue’s response that the plaintiff could not “receive treaty
    benefits in accordance with the provisions in the Ireland–USA Double Taxation
    Convention,’” the Tax Treaty. See 
    id.
     (alteration added). The Court of Federal Claims in
    McManus held “that Ireland Revenue’s response to the IRS is expressly contemplated by
    Articles 26 and 27 of the Tax Treaty,” and, therefore, that both the IRS’s request and
    Ireland Revenue’s response could be used to interpret the Tax Treaty. See id. at 624-25.
    Protestor asserted that “in McManus, the Court started its interpretation with the
    language of the Tax Treaty,” and argued that the McManus decision “sought to uphold
    the original intent of the parties as they negotiated the relevant treaty.” (citing McManus
    v. United States, 130 Fed. Cl. at 616-23). Defendant responded that in McManus, “this
    Court looked to the entire context of a treaty to interpret its terms,” including “the bilateral
    framework between Ireland and the United States” as well as “the exchange of
    information between Ireland and the United States” in that “framework which was
    described in the treaty,” (citing McManus v. United States, 130 Fed. Cl. at 621, 624-25),
    and defendant argued by analogy for the court to consider the “diplomatic exchanges” in
    the above captioned bid protest.
    In its supplemental brief, defendant cited to the Federal Circuit decision in
    Barsebäck Kraft AB v. United States, 
    121 F.3d 1475
     (Fed. Cir. 1997), which concerned
    treaties with Sweden and Spain regarding nuclear energy that one Swedish contractor
    and one Spanish contractor providing uranium enrichment services to the United States
    argued had been violated by the United States’ “offering lower prices to utilities entering
    new contracts” with the United States Enrichment Corporation. See 
    id. at 1482
    . The
    Federal Circuit in Barsebäck held that the treaties at issue did not speak to the pricing of
    uranium enrichment services, and, therefore, the treaties had not been violated by the
    offering of lower prices to newer contractors. See 
    id.
     The Federal Circuit found that “there
    113
    is nothing in the treaty or in the diplomatic correspondence that guarantees Barsebäck
    the lowest price. The treaty is silent on pricing. The diplomatic correspondence says only
    that charges for enrichment services will be those in effect for users in the United States
    at the time of delivery.” 
    Id.
     Defendant cited to this language from the Federal Circuit’s
    decision in Barsebäck to argue that “[t]he Federal Circuit has also looked to diplomatic
    correspondence where an international agreement left a term undefined.” (alteration
    added) (citing Barsebäck Kraft AB v. United States, 
    121 F.3d at 1482
    ). Moreover, with
    respect to diplomatic correspondence, the Federal Circuit in Barsebäck also wrote:
    “Diplomatic correspondence, however, provides that with respect to any contract that
    Sweden, or authorized persons, execute with the government, charges for enrichment
    services will be those in effect for users in the United States at the time of delivery.”
    Barsebäck Kraft AB v. United States, 
    121 F.3d at 1482
    .
    As the precedential decisions of the United States Supreme Court and the Court
    of Appeals for the Federal Circuit, as well as the decisions of the Court of Federal Claims
    and its predecessor courts demonstrate, this court’s interpretation of the agreements
    between the United States and Denmark, including the 1951 Agreement, 1991
    Memorandum of Understanding, 2004 Agreement, and 2009 Agreement, is not
    necessarily limited to the plain text of these agreements, as protestor claims. Rather,
    “when the language of a treaty provision ‘only imperfectly manifests its purpose,’” the
    court “must ‘examine not only the language, but the entire context of [the] agreement.’”
    Nat’l Westminster Bank, PLC v. United States, 
    512 F.3d at 1353
     (alteration added)
    (quoting Great-West Life Assur. Co. v. United States, 
    230 Ct. Cl. at 481
    ). Because the
    court should “read the treaty in a manner consistent with the shared expectations of the
    contracting parties,” Lozano v. Montoya Alvarez, 
    572 U.S. at 12
     (emphasis in original)
    (internal quotations omitted), the court looks to “[t]he course of conduct of parties to an
    international agreement” as “evidence of its meaning.” O’Connor v. United States, 
    479 U.S. at 33
     (alteration added). Consistent with historical practice, when assessing the
    signatory governments’ course of conduct, the court may consider diplomatic notes or
    other “diplomatic correspondence” containing “expressions of intent,” including diplomatic
    correspondence from after the execution of an international agreement, Coplin v. United
    States, 
    761 F.2d at 691
    ; see also McManus v. United States, 130 Fed. Cl. at 620, as
    evidence of the signatory governments’ “practical construction” of the agreement’s terms.
    See Sumitomo Shoji Am., Inc. v. Avagliano, 
    457 U.S. at 183-85
    ; Factor v. Laubenheimer,
    
    290 U.S. at 294-95
    ; Nielsen v. Johnson, 
    279 U.S. at 52
    ; United States v. Texas, 
    162 U.S. at 23
    .
    In addition to general guidance, supported by the above-discussed cases, that the
    court may consider the diplomatic correspondence by the signatory governments to
    interpret an international agreement, in certain cases, courts also have referred to
    diplomatic correspondence which postdated the formation and ratification of the treaty or
    international agreement under consideration to discern the intent of the participating
    governments. The earliest example identified of the consideration of post-ratification
    correspondence to determine the signatory governments’ intent is found in the Supreme
    Court’s decision in Nielsen v. Johnson. As discussed above, the Supreme Court in
    Nielsen interpreted a treaty ratified in 1826 and considered messages between the United
    114
    States and Denmark from March 1824 to April 1826 which predated the treaty, as well as
    a pair of correspondences from after the treaty’s ratification, albeit, in Nielsen, shortly
    thereafter in November 1826. See Nielsen v. Johnson, 
    279 U.S. at 54
    . In the first such
    postdated correspondence, dated November 10, 1826, the United States Secretary of
    State sought to clarify the United States government’s intent regarding a certain treaty
    provision:
    “The object which the government of the United States had in view in that
    stipulation, was to secure the right of their citizens to bring their money and
    movable property home from the Danish islands, free from charges or duties
    and especially from the onerous law, known in those islands, under the
    denominations of sixths and tenths. This object was distinctly known to Mr.
    Pedersen, throughout the whole of the negotiation, and was expressly
    communicated by me to him in writing.”
    
    Id.
     According to the Supreme Court, the representative of the Danish government sent a
    response the next day confirming that Denmark would act with respect to the relevant
    treaty provision “‘conformably to the intent and meaning thereof as by you stated.’” See
    
    id.
     While the post-ratification correspondence in Nielsen, dated November 10-11, 1826,
    postdated the treaty at issue, dated April 26, 1826, by only a few months, see 
    id.,
     the
    United States Supreme Court also has considered diplomatic correspondence further
    removed in time from the treaty being interpreted. For example, in Todok v. Union State
    Bank of Harvard, Nebraska, as noted above, the Supreme Court interpreted
    article 6 of the treaty with Sweden of April 3, 1783 (
    8 Stat. 6064
    ), revived by
    the treaty with Sweden and Norway of Sept. 4, 1816 (
    8 Stat. 232
    , 240) which
    was replaced by the treaty with Sweden and Norway of July 4, 1827 (
    8 Stat. 346
    , 354) now in force with Norway (Sen. Doc., 61st Cong., 2d Sess., No.
    357, vol. 48 (2 Malloy), p. 1300).
    Todok v. Union St. Bank of Harvard, Neb., 
    281 U.S. at 452-53
    . When determining the
    proper meaning of the term “goods and effects” under the treaty, which had originally
    been written in French, the Supreme Court in Todok referred to the diplomatic note of the
    Swedish Minister to the United States, dated December 12, 1910, in which “the Swedish
    Minister stated his understanding that the authorities in Sweden had always held that the
    words ‘goods and effects' in article 6 of the treaty of 1783 include real estate.” See 
    id. at 454
    . The Supreme Court in Todok did not comment upon, let alone disapprove of, the
    evidentiary value of the Swedish Minister’s note, despite the note postdating the treaty at
    issue by at least 83 years.
    The Supreme Court’s decision in Sumitomo presents a more recent reference to
    the use of post-ratification diplomatic correspondence for interpretation of the intent of the
    words of a treaty. The Supreme Court in Sumitomo interpreted a treaty dated April 2,
    1953, see Sumitomo Shoji Am., Inc. v. Avagliano, 
    457 U.S. at 179
    , and referred to two
    pieces of diplomatic correspondence from the Japanese government, dated February 26,
    1982, and April 21, 1982, to support its conclusion that “[t]he Governments of Japan and
    115
    the United States support this interpretation of the Treaty.” 
    Id. at 183-84
     (alteration
    added). The Supreme Court in Sumitomo did not remark on an approximately 29-year
    difference between the treaty under consideration and the diplomatic correspondence
    stating the Japanese government’s interpretation, nor did the Supreme Court remark
    upon the diplomatic notes being provided after litigation had already commenced and a
    few months before the Supreme Court decided the case. See 
    id.
    As discussed above, similar to the Supreme Court’s holdings in Nielsen, Todok,
    and Sumitomo, the Federal Circuit in Coplin relied upon a diplomatic note sent by the
    government of Panama in 1985 to interpret a 1977 Implementation Agreement of the
    1977 Panama Canal Treaty between the United States and Panama. See Coplin v. United
    States, 
    761 F.2d at 689-90
    . The Federal Circuit in Coplin did not object to the Panamanian
    diplomatic note postdating the Implementation Agreement between the United States and
    Panama by approximately eight years, nor did the fact that the Panamanian diplomatic
    note had been produced while the Coplin case was on appeal, and supplied to the Federal
    Circuit the morning of oral argument in that case, prevent the Panamanian note’s
    consideration in the Federal Circuit’s majority opinion. See 
    id. at 691
    .56 Moreover, the
    Supreme Court in O’Connor affirmed the Federal Circuit’s Coplin decision and did not
    challenge the Federal Circuit’s reliance on the Panamanian diplomatic note. See
    O’Connor v. United States, 
    479 U.S. at
    33 n.2.
    As indicated above, protestor argued that Diplomatic Note No. 127 and other post-
    ratification diplomatic correspondence have lesser evidentiary value, if even relevant, as
    to the signatory governments’ intent with respect to the international agreements between
    the United States and Denmark because the diplomatic correspondences postdate the
    2009 Agreement, in particular Diplomatic Note No. 127, written in 2020, which postdates
    the 2009 Agreement by approximately 11 years. The examined precedent reveals no
    explicit prohibition against consideration of post-ratification diplomatic correspondence in
    order to interpret a treaty or international agreement. In fact, in the decisions examined
    above which considered post-ratification diplomatic correspondence, neither the United
    States Supreme Court, nor the United States Court of Appeals for the Federal Circuit,
    have rejected the possible evidentiary value of postdated diplomatic correspondence as
    to the signatory governments’ intent regarding the meaning of treaty words in the proper
    case. Rather, the Supreme Court and the Federal Circuit both have considered post-
    ratification diplomatic correspondence of varying temporal distances from the relevant
    international agreements as able to assist to reach an understanding regarding the intent
    of the signatories to the relevant treaty documents. See Sumitomo Shoji Am., Inc. v.
    Avagliano, 
    457 U.S. at 183-84
     (29 years); Todok v. Union St. Bank of Harvard, Neb., 
    281 U.S. at 454
     (83 to 127 years); Nielsen v. Johnson, 
    279 U.S. at 54
     (a few months); Coplin
    v. United States, 
    761 F.2d at 691
     (eight years). Therefore, the court may consider the
    56 The concurrence by three members of the Federal Circuit panel in Coplin referred to
    the Panamanian diplomatic note as “the late filed concurrence by the Panamanian
    government,” although the concurrence only declined to consider the Panamanian
    diplomatic note because “that evidence was not necessary to the above decisions and is
    not necessary here.” See Coplin v. United States, 
    761 F.2d at 692
     (Nies, J., concurring).
    116
    postdated Diplomatic Note No. 127, as well as the 2013 diplomatic correspondence, to
    determine the meaning of the 2009 Agreement, which protestor agrees is binding on the
    parties, to assist the court’s interpretation of the words “Danish/Greenlandic sources”
    within the 2009 Agreement.
    In its supplemental brief, protestor cited to the United States Supreme Court’s
    recent decision in GE Energy Power Conversion France SAS, Corp. v. Outokumpu
    Stainless USA, LLC, 
    140 S. Ct. 1637
    , to argue against reliance upon post-ratification
    materials to interpret the agreements between the United States and Denmark. The GE
    Energy Power Conversion France case, however, is distinguished from the bid protest
    currently before this court. The United States Supreme Court in GE Energy Power
    Conversion France addressed the question of “whether the Convention on the
    Recognition and Enforcement of Foreign Arbitral Awards,” a “multilateral treaty” also
    called the “New York Convention,” “conflicts with domestic equitable estoppel doctrines
    that permit the enforcement of arbitration agreements by nonsignatories.” GE Energy
    Power Conversion France SAS, Corp. v. Outokumpu Stainless USA, LLC, 
    140 S. Ct. at 1642, 1644
    . In order to “determine whether the equitable estoppel doctrines permitted
    under Chapter 1 of the FAA [Federal Arbitration Act] ‘conflict with . . . the [New York]
    Convention,’” the Supreme Court employed “familiar tools of treaty interpretation” to
    analyze the New York Convention. 
    Id. at 1644-45
     (ellipsis in original; alterations added)
    (quoting 
    9 U.S.C. § 208
     (2018)). The Supreme Court in GE Energy Power Conversion
    France SAS held that “[t]he [New York] Convention is simply silent on the issue of
    nonsignatory enforcement,” and that “[t]his silence is dispositive here because nothing in
    the text of the [New York] Convention could be read to otherwise prohibit the application
    of domestic equitable estoppel doctrines.” Id. at 1645 (alterations added). The Supreme
    Court further explained: “‘Because a treaty ratified by the United States is “an agreement
    among sovereign powers,” we have also considered as “aids to its interpretation” the
    negotiation and drafting history of the treaty as well as “the postratification understanding”
    of signatory nations.’” Id. at 1645-46 (quoting Medellin v. Texas, 
    552 U.S. at 507
     (quoting
    Zicherman v. Korean Air Lines Co., 
    516 U.S. at 226
    )). In relevant part, the Supreme Court
    in GE Energy Power Conversion France SAS stated:
    “[T]he postratification understanding” of other contracting states may also
    serve as an aid to our interpretation of a treaty's meaning. Medellín, 
    552 U.S. at 507
    , 
    128 S. Ct. 1346
     (internal quotation marks omitted). To discern
    this understanding, we have looked to the “[d]ecisions of the courts of other
    Convention signatories,” El Al Israel Airlines, Ltd. v. Tsui Yuan Tseng, 
    525 U.S. 155
    , 175, 
    119 S. Ct. 662
    , 
    142 L. Ed. 2d 576
     (1999), as well as the
    “postratification conduct” of the governments of contracting states,
    Zicherman, 
    516 U.S. at 227
    , 
    116 S. Ct. 629
    .
    GE Energy Power Conversion France SAS, Corp. v. Outokumpu Stainless USA, LLC,
    
    140 S. Ct. at 1646
     (alterations in original). Accordingly, the Supreme Court considered
    decisions by “[t]he courts of numerous contracting states” and the “domestic legislation”
    from other signatory countries, as well as “a recommendation issued by the United
    Nations Commission on International Trade Law” which “adopts a nonexclusive
    117
    interpretation of Article II(1) and (2),” and the Supreme Court held that “the weight of
    authority from contracting states indicates that the New York Convention does not prohibit
    the application of domestic law addressing the enforcement of arbitration agreements.”
    See 
    id. at 1646-47
     (alteration added). The Supreme Court further explained, however,
    that
    [t]he court decisions, domestic legislation, and UN recommendation relied
    on by the parties occurred decades after the finalization of the New York
    Convention's text in 1958. This diminishes the value of these sources as
    evidence of the original shared understanding of the treaty's meaning.
    Moreover, unlike the actions and decisions of signatory nations, we have
    not previously relied on UN recommendations to discern the meaning of
    treaties. See also Yang v. Majestic Blue Fisheries, LLC, 
    876 F.3d 996
    ,
    1000-1001 (CA9 2017) (declining to give weight to the 2006 UN
    recommendation). But to the extent this evidence is given any weight, it
    confirms our interpretation of the Convention's text.
    Id. at 1647 (alteration added).
    While the Supreme Court in GE Energy Power Conversion France indicated that
    the fact that the post-ratification materials “occurred decades after” the New York
    Convention “diminishes the value of these sources as evidence of the original shared
    understanding of the treaty’s meaning,” the Supreme Court did not wholly discount the
    post-ratification materials, and explained that “to the extent this evidence is given any
    weight, it confirms our interpretation of the Convention’s text.” Id. Moreover, the Supreme
    Court in GE Energy Power Conversion France considered “court decisions, domestic
    legislation,” and a “UN recommendation.” See id. In the above captioned protest before
    this court, diplomatic correspondence like Diplomatic Note No. 127, expressing the United
    States’ and Denmark’s shared understanding of the language of the binding international
    agreements, are both bilateral and developed consistent with the existing consultative
    framework established by the 1951 Agreement, the 1991 Memorandum of
    Understanding, the 2004 Agreement, and the 2009 Agreement. The diplomatic
    correspondences which this court consults in the current protest to interpret the phrase
    “Danish/Greenlandic sources,” therefore, bear no resemblance to the post-ratification-
    materials addressed by the Supreme Court in GE Energy Power Conversion France SAS,
    Corp. v. Outokumpu Stainless USA, LLC, 
    140 S. Ct. at 1645-46
    . For these reasons, the
    Supreme Court’s decision in GE Energy Power Conversion France does not prevent this
    court in the current bid protest from using post-ratification diplomatic correspondences,
    including Diplomatic Note No. 127, to interpret the international agreements between the
    United States and Denmark.
    In the above captioned bid protest, this court is presented with diplomatic
    correspondence during which the United States and Denmark conferred and reached
    agreements as to the proper interpretation of the terms of the 2009 Agreement, consistent
    with the consultative process contemplated by the foundational 1951 Agreement, the
    1991 Memorandum of Understanding, and the 2004 Agreement. During the 11 years
    118
    between the 2009 Agreement and Diplomatic Note No. 127, the United States and
    Denmark continued to engage in consultation and negotiation, including the exchange of
    diplomatic notes, to find a mutually-agreeable way in which to continue the relationship
    between the United States, Denmark, and Greenland, including their interpretation of the
    term “Danish/Greenlandic sources” which was written for the first time into the 2009
    Agreement. Taking into account the facts of this case and the relevant cases, this court
    begins its analysis by examining the texts of the international agreements at issue. See
    Medellin v. Texas, 
    552 U.S. at 506-07
    . The Administrative Record in the current protest
    includes four documents which both protestor and defendant agree represent binding
    agreements between the United States and Denmark: the 1951 Agreement, the 1991
    Memorandum of Understanding, the 2004 Agreement, and the 2009 Agreement. The
    1951 Agreement, which, as described above, is the foundational document of the
    international relationship between the United States and Denmark with respect to
    American military operations in Greenland and Thule Air Base, includes provisions which
    contemplate continuing cooperation and consultation between the signatory governments
    to the benefit of all the governments, for the United States, its continued military presence
    in Greenland, for Denmark and Greenland, the continuing security, economic, and other
    benefits of the United States’ presence. Article I of the 1951 Agreement provides that the
    United States and Denmark will cooperate “in order to promote stability and well-being in
    the North Atlantic Treaty area by uniting their efforts for collective defense and for the
    preservation of peace and security and for the development of their collective capacity to
    resist armed attack,” and “will each take such measures as are necessary to carry out
    expeditiously their respective and joint responsibilities in Greenland.” 1951 Agreement,
    art. I, at 2. The 1951 Agreement further provides, at Article VI, that the United States
    government “agrees to cooperate to the fullest degree with the Government of the
    Kingdom of Denmark and its authorities in Greenland in carrying out operations under
    this Agreement.” 1951 Agreement, art. VI at 9. The 1951 Agreement additionally provides,
    at Article X, in the event of “the coming into force of a NATO agreement,” that “[i]f it should
    appear that any of the provisions of such NATO agreement may be inappropriate to the
    conditions in Greenland, the two Governments will consult with a view to making mutually
    acceptable adjustments.” (capitalization in original; alteration added). Moreover, the 1951
    Agreement provides, at Article XIII, that “[q]uestions of interpretation which may arise in
    the application of this Agreement shall be submitted to the Minister for Foreign Affairs of
    the Kingdom of Denmark and to the United States Ambassador to Denmark.” 1951
    Agreement, art. XIII at 13 (alteration added).
    The 1991 Memorandum of Understanding includes language which augments the
    continuing and cooperative relationship between the United States and Denmark with
    respect to military operations in Greenland. In Article VII, titled “Permanent Committee,”
    the 1991 Memorandum of Understanding provides for the establishment of “a United
    States-Danish Permanent Committee,” and, further:
    3. The Permanent Committee shall consult and exchange information on
    all matters pertaining to the US military presence in Greenland in general
    and to the present MOU in particular. The US representative will provide
    the Danish representative with timely information concerning any plans
    119
    for significant changes to US military operations or facilities which could
    have an impact on the economy or environment in Greenland. Matters
    falling under the scope of the United States-Danish Committee on
    Greenland Projects will not be dealt with by the Permanent Committee.
    4. In the event that disagreement arises over a problem which cannot be
    resolved by the Permanent Committee, the issue shall be referred for
    resolution through diplomatic channels.
    1991 Memorandum of Understanding, art. VII (capitalization and emphasis in original).
    The 2004 Agreement, which amended the 1951 Agreement, expands on the
    United States and Denmark’s commitments to cooperation and consultation. The 2004
    Agreement provides, in “Article 3: Local Cooperation,” in relevant part, that “[c]onsistent
    with the Defense Agreement [of 1951], as amended herein, and the Memorandum of
    Understanding of March 13, 1991,” the United States shall “consult with and inform the
    Government of the Kingdom of Denmark, including the Home Rule Government of
    Greenland, prior to the implementation of any significant changes to United States military
    operations or facilities in Greenland.” 2004 Agreement, art. 3, ¶ 1.c. (emphasis in original;
    alterations added). The 2004 Agreement further provides, in the same article, Article 3,
    that the United States and Denmark “agree that to enhance local cooperation,” and that
    the signatory governments
    shall consult without undue delay regarding any question which one of the
    Parties may raise concerning matters pertaining to the U.S. military
    presence in Greenland and covered by the Defense Agreement and this
    agreement. To the extent that such matters cannot be resolved through
    local consultation, the Parties shall consult with each other either in the
    Permanent Committee or through diplomatic channels, as appropriate.
    2004 Agreement, art. 3, ¶ 2.b.
    The terms of the 1951 Agreement, the 1991 Memorandum of Understanding, and
    the 2004 Agreement, when considered together, make clear and establish that the United
    States and Denmark intended from the outset that the relationship between the two
    countries would be characterized by consultation on concerns either government might
    express and mutual resolution of disputes, and that such intention should carry through
    the subsequent agreements regarding the relationship between the United States and
    Denmark. Further, the 1951 Agreement, the 1991 Memorandum of Understanding, and
    the 2004 Agreement set forth a tiered system to resolve disputes, through different
    organizations of the United States and Denmark, first through “local consultation,” then
    as to which issues should be elevated to the established Permanent Committee as
    described in the 1991 Memorandum of Understanding for consideration, or ultimately “as
    appropriate,” questions can be referred “through diplomatic channels” initially with
    “[q]uestions of interpretation” to be “submitted to the Minister for Foreign Affairs for the
    Kingdom of Denmark and to the United States Ambassador to Denmark.” (alteration
    added).
    120
    The 2009 Agreement, which both protestor and defendant also agree is a binding
    agreement between the United States and Denmark, contains the relevant
    “Danish/Greenlandic sources” language at issue in the above captioned bid protest. The
    2009 Agreement includes a requirement that the United States and Denmark “shall
    procure directly from Danish/Greenlandic sources,” indicates by its text that it is a product
    of the consultative framework established by the United States and Denmark’s prior
    agreements. The 2009 Agreement “refer[s] to recent discussions between
    representatives of the two governments regarding procedures for procurement of services
    for the U.S. Air Base at Thule,” and states that “[a]s a result of the discussions,” it sets
    forth what would become the amendatory language. (alterations added). Importantly,
    while the 2009 Agreement became a binding agreement upon acceptance by the Danish
    government, prior to such acceptance, the 2009 Agreement was incorporated in a piece
    of diplomatic correspondence, Diplomatic Note No. 053, dated July 16, 2008. As a
    diplomatic note it represents the operation and consummation of the consultation process
    between the United States and Denmark established by the prior agreements. Following
    “discussions,” Diplomatic Note No. 053 was sent by the United States Embassy in
    Copenhagen to the Danish Ministry of Foreign Affairs, which are the offices of the two
    officials noted as having responsibilities for “[q]uestions of interpretation” in the 1951
    Agreement, see 1951 Agreement, art. XIII at 13 (alteration added), and involving the
    “diplomatic channels” contemplated by the 2004 Agreement. See 2004 Agreement, art.
    3, ¶ 2.b.
    Similar to the 2009 Agreement, the notes of the 2013 diplomatic correspondence,
    setting forth the eligibility criteria for the earlier contract, the 2015 Joint Statement, and
    Diplomatic Note No. 127 from 2020, setting forth the eligibility criteria at issue in the above
    captioned bid protest, by their plain language were part of the continuous, consultative
    framework established by the United States and Denmark in multiple agreements. The
    2013 diplomatic correspondence between the United States Embassy and the Danish
    Ministry of Foreign Affairs contains references to discussions between United States and
    Danish officials “regarding the Thule Air Base Maintenance Contract criteria” and sets
    forth “a solution” to the issue of “what constitutes a company eligible to participate in the
    procurement,” while also “maintaining the spirit of the agreements underlying the recent
    procurement procedure.” The responsive note from the United States dated December
    13, 2013 agrees that the “criteria will allow the United States to fulfill our obligations” and
    expresses appreciation for “your ministry’s collaboration on this issue.”
    The 2015 Joint Statement by the United States and Denmark expressly refers to
    the consultative process established by the international agreements. The 2015 Joint
    Statement provides that the United States and Denmark had collaborated “to discuss
    concerns relating to the interpretation of international agreements between the two
    governments pertaining to the definition of a Danish/Greenlandic enterprise,” and “high-
    level consultations between the Kingdom of Denmark and the United States began in
    Washington, DC, regarding the international agreements applicable to the Thule Air Base
    Maintenance Contract solicitation.” The 2015 Joint Statement concludes by explaining
    that the countries would continue to engage “expeditiously and through diplomatic
    121
    channels,” to resolve “all issues between the two governments relating to the
    interpretation of those international agreements in accordance with Article XIII(2) of the
    1951 Defense of Greenland Agreement (as amended),” a reference to the 1951
    Agreement’s and subsequent agreements’ establishment of the cooperative framework
    between the United States and Greenland.
    Diplomatic Note No. 127, from the United States Embassy, and its acceptance in
    reply correspondence by the Danish Ministry of Foreign Affairs, contain similar language
    to the 2013 diplomatic correspondence. Diplomatic Note No. 127 refers to a recent “Joint
    Statement” and to “ongoing discussions between the United States and the Kingdom of
    Denmark” concerning eligibility criteria for Thule Air Base procurement, and offers, as the
    solutions to those discussions, in order “to ensure that the Thule Base Maintenance
    Contract is awarded to a ‘Danish/Greenlandic source’ as required by the [1991]
    Memorandum of Understanding,” (alteration added), the eligibility criteria at issue in the
    above captioned bid protest. By all the references to cooperation and discussion in the
    2013 diplomatic correspondence and in Diplomatic Note No. 127, and by the involvement
    of the United States Embassy and the Danish Ministry of Foreign Affairs, the 2013
    diplomatic correspondence and Diplomatic Note No. 127 fit squarely within the
    consultative process contemplated by the agreed-to binding international agreements
    between the United States and Denmark starting with the 1951 Agreement through the
    2009 Agreement and present relationship, and are consistent with the subsequent
    consultative and written communications between the parties. In particular, because both
    the 2013 diplomatic correspondence and Diplomatic Note No. 127 address the
    implementation of the phrase “Danish/Greenlandic sources” for subsequent
    procurements, the diplomatic notes and the discussions preceding them constitute the
    “submi[ssion]” of a “[q]uestion[] of interpretation” “to the Minister for Foreign Affairs of the
    Kingdom of Denmark and to the United States Ambassador to Denmark” and to their
    governments, see 1951 Agreement, art. XIII at 13 (alterations added), and the referral of
    disputes “through diplomatic channels, as appropriate.” See 2004 Agreement, art. 3, ¶
    2.b. Diplomatic Note No. 127 and the 2013 diplomatic correspondence, along with the
    2015 Joint Statement, are within the terms contemplated and established in the 1951
    Agreement, as well as in the later agreements which also contemplate that consultation
    and cooperation will take place between the United States and Denmark to further the
    joint purpose of cooperation regarding the Thule Air Base to the mutual benefit of all the
    countries involved. Although the court recognizes the credibility questions which can be
    raised regarding the use of post-ratification documents to interpret the words in
    international agreements, the use of “diplomatic channels” to continue to address a
    question of treaty interpretation, see 1951 Agreement, art. XIII at 13 (alterations added),
    was “expressly contemplated” by the text of the 1951 Agreement, the 1991 Memorandum
    of Understanding, the 2004 Agreement, and the 2009 Agreement. See McManus v.
    United States, 130 Fed. Cl. at 624-25. In Vectrus’ protest at issue in this Opinion, the
    court concludes, given the importance of the continuing relationships, security concerns,
    and practical considerations at issue in the relationship between the United States and
    the Kingdom of Denmark, it is appropriate in this protest to consider the evolving
    interpretations which were set forth in the diplomatic correspondences by the United
    122
    States and Denmark to sustain and further develop the non-static, mutually beneficial
    relationship between the two governments regarding Thule Air Base.
    In addition to the broader textual context of the four binding agreements, the
    specific text of the 2009 Agreement, in which the term “Danish/Greenlandic sources” was
    included by bilateral agreement, is particularly relevant. Protestor argued that the term
    “Danish/Greenlandic sources” in the 2009 Agreement “does not define the word ‘sources’
    in terms of the nationality of an offeror’s corporate affiliates.” Because the phrase
    “Danish/Greenlandic sources” is accompanied in the 2009 Agreement by a mention of
    “commercial enterprises for goods and services,” protestor argued in its motion for
    judgment on the Administrative Record that “the term ‘Danish/Greenlandic sources’ refers
    to entities providing goods or services which are themselves Danish or Greenlandic. The
    term does not have the effect of requiring corporate parents or affiliates to be Danish or
    Greenlandic.” Defendant responded that the 1991 Memorandum of Understanding, as
    amended by the 2009 Agreement, “did not define ‘Danish/Greenlandic source,’” that the
    United States and Denmark “were free to meet” and the process to do so had been
    established to clarify the meaning of the term “Danish/Greenlandic sources” by diplomatic
    correspondence and continued consultation, and that there were relevant subsequent
    exchanges between the United States and the Kingdom of Denmark to clarify the ongoing
    relationship between the nations involved.
    Although the 2009 Agreement and the 1991 Memorandum of Understanding do
    not provide a definition of what makes a “source” “Danish/Greenlandic,” in the diplomatic
    exchanges between the United States and Denmark, including the 2013 diplomatic
    correspondence and Diplomatic Note No. 127, are further expressions of the signatory
    governments’ intent as to the meaning of “Danish/Greenlandic sources” within their
    relationship. Credibility should be given with respect “to the intent of both signatories”
    when interpreting the underlying treaties and international agreements, see Nat’l
    Westminster Bank, PLC v. United States, 
    512 F.3d at 1353
    , especially in the case
    currently under review in which the consistency of the relationship and concerns of both
    parties to the relationship have been clearly expressed. Therefore, to interpret the term
    “Danish/Greenlandic sources,” the court considers the subsequent diplomatic
    correspondence and agreement between the United States and the Kingdom of Denmark
    in which the signatory parties have expressed their intent through a mutually beneficial
    process of cooperation.
    The Administrative Record before the court reflects that it was the United States
    and Denmark’s shared expectation that discussions between the parties would continue
    to develop the diplomatic relationship which includes that the phrase “Danish/Greenlandic
    sources” could be considered a dynamic phrase based on future discussions. The 1991
    Memorandum of Understanding provided that the United States and Denmark “may
    procure directly from any US or Danish/Greenlandic source.” The 2009 Agreement
    amended the 1991 Memorandum of Understanding’s language with the requirement that
    the United States and Denmark “shall procure directly from Danish/Greenlandic sources.”
    (emphasis added). While not dispositive, the court finds the decision to remove the words
    “US or” from the agreement between the United States and Denmark, leaving only a
    123
    reference to “Danish/Greenlandic sources,” indicative that the United States agreed to
    Denmark’s desire to establish a preference for Danish or Greenlandic companies in future
    contracting.57
    The United States and Denmark engaged in diplomatic correspondence to define
    the term “Danish/Greenlandic sources” in the 2009 Agreement, consistent with the 1951
    Agreement, the 1991 Memorandum of Understanding, the 2004 Agreement, and the 2009
    Agreement. The 2013 diplomatic correspondence, which established the eligibility criteria
    for the prior contract, provides that offerors would “[s]ubmit corporation certification
    (Selskabscertifikat m. oblat) verifying that the company is registered in the Kingdom of
    Denmark,” and that “THE REGISTERED OFFICE OF THE ENTERPRISE SHALL BE IN
    THE KINGDOM OF DENMARK AND SHALL NOT BE REGISTERED AS A SUBSIDIARY
    OF FOREIGN COMPANY.” (capitalization in original; alteration added). The Danish State
    Secretary for Foreign Policy in the December 9, 2013 letter referred to the 2013 criteria
    set forth in the diplomatic correspondence as requiring an offeror “to prove that they
    qualify as a Danish or Greenlandic company,” which would have the effect of “maintaining
    the spirit of the agreement underlying the recent procurement procedure,” i.e., in the 2014
    Solicitation, and consistent with the Danish government’s belief that “the purpose of
    restricting participation in the procurement to Danish/Greenlandic companies is to ensure
    Greenland and Greenlandic society greatest possible benefits from the agreement.” The
    United States Ambassador in response to the Danish government, similarly, expressed
    the sentiment that “our use of these criteria will allow the United States to fulfill our
    obligations under our bilateral agreements related to Thule while streamlining the process
    for determining the eligibility of potential bidders.”
    The eligibility of contractors to compete for the Thule Base Maintenance Contract
    was at issue in the Per Aarsleff bid protest litigation, discussed above, concerning the
    prior contract award to Exelis, now Vectrus. The Judge of the United States Court of
    Federal Claims in Per Aarsleff “excise[d]” a portion of the eligibility criteria in the 2014
    Solicitation of the earlier contract. See Per Aarsleff A/S v. United States, 
    121 Fed. Cl. at 625
     (alteration added). Because of this “excis[ion]” of the 2014 Solicitation’s language the
    Judge held that Exelis should have been ineligible for award as the subsidiary of a United
    States company. See 
    id. at 630
     (alteration added). The Federal Circuit on appeal
    reversed the Judge of the Court of Federal Claims and the Federal Circuit concluded that
    Exelis was eligible for award of the earlier contract because the criterion at issue “refers
    to whether the CVR [Central Business Register] facially indicates the company is a
    subsidiary of a foreign company,” although “as the three unsuccessful bidders concede,
    57 The “Agreed Record” attached to the July 13, 1956 letter provides that in the 1956
    Agreement the United States and Denmark had agreed that “Construction, Operation and
    Maintenance contracts for works in the defense areas in Greenland will in future only be
    awarded to Danish and American enterprises.” Although neither protestor nor defendant
    cites to the 1956 Agreement in the above captioned protest, the contractual eligibility
    limitation to “Danish and American enterprises” as early as 1956 indicates that the desire
    to establish a preference for Danish contractors has been evident since the first years
    after the 1951 Agreement.
    124
    it was impossible for the CVR to facially indicate such status,” because no such status
    existed on the Central Business Register. See Per Aarsleff A/S v. United States, 
    829 F.3d at 1311-12
     (alteration added). The Federal Circuit’s Per Aarsleff opinion includes the
    following description of the development of the incumbent contract’s eligibility criteria:
    During the course of this effort, [[name redacted]], a State Department
    employee stationed at the U.S. Embassy in Denmark, informed the Air
    Force contracting officer by email that “[i]n the searchable part of the CVR
    [Det Central Virksomhedsregister, i.e., the Danish central business register]
    there is an information point called ‘type of company/virksomhedsform’ that
    [has] ‘subsidiary of foreign company’ as a possibility, so there is a way to
    see if the company is fully registered as Danish or acting as a foreign
    subsidiary in Denmark.” J.A. 25, 128251. As a result, the Air Force was
    under the belief, later shown to be mistaken, that the CVR provided a ready
    means for determining whether a company was a subsidiary of a foreign
    company. According to Copenhagen Arctic A/S (“Copenhagen Arctic”), one
    of the three unsuccessful bidders, the CVR contained an option to indicate
    whether a firm was registering as “[f]ilialer af udenlandske aktieselskaber
    (in English: [b]ranch of a foreign owned public limited company).” Per
    Aarsleff, 
    121 Fed. Cl. at
    610 n. 8 (emphasis added). Greenland Contractors
    asserts the State Department employee, [[name redacted]], “appears to
    have mistranslated the word ‘filial’ in Danish to mean ‘subsidiary,’ when that
    word in fact means ‘branch’ or ‘branch office.’”
    Per Aarsleff A/S v. United States, 
    829 F.3d at 1306-07
     (capitalization, emphasis, and
    alterations in original). The documents referred to in the Federal Circuit’s Per Aarsleff
    decision, as quoted above, do not appear to be included in the Administrative Record in
    the above captioned bid protest. The factual information contained in the Federal Circuit’s
    Per Aarsleff decision, however, when considered in conjunction with the 2013 diplomatic
    correspondence in the Administrative Record in the above captioned bid protest, indicates
    that the eligibility criteria in the prior contract were suggested in 2013, and accepted, with
    the intention of excluding subsidiaries of foreign companies from contract award. While
    the United States and Denmark did not ultimately exclude foreign subsidiaries from
    competing for the prior contract discussed in Per Aarsleff, that was due, as the Federal
    Circuit noted, to an apparent “mistranslat[ion]” of terms in the Danish Central Business
    Register, not necessarily to a lack of intent to exclude subsidiaries of foreign companies.
    See 
    id. at 1307
     (alteration added).
    Following the award of the incumbent contract to Exelis, now Vectrus, and the
    unsuccessful attempt to protest that award, Exelis did perform the incumbent contract.
    The United States and Denmark continued to engage in further negotiations, including
    the resultant Diplomatic Note No. 127, to produce eligibility criteria which are incorporated
    in the Solicitation No. FA2523-21-R-0001 at issue in the protest currently before this court
    which involves the definition of the term “Danish/Greenlandic sources.” Consistent with
    the cooperative framework established by the 1951 Agreement, the 1991 Memorandum
    125
    of Understanding, the 2004 Agreement, and the 2009 Agreement,58 the diplomatic
    correspondences of 2013 and Diplomatic Note No. 127 express the United States and
    Denmark’s negotiated, mutually understood intent as to how to continue to implement the
    relationship between the United States, Denmark, and Greenlandic, now including for
    Thule Air Base, established originally in the 1951 Agreement and subsequent
    agreements. In accord with the two countries’ expectations, the court gives effect to the
    intent of the United States and Denmark, as expressed in each of the agreements and
    diplomatic correspondence, including Diplomatic Note No. 127, to interpret
    “Danish/Greenlandic sources” as expressing an intent to exclude subsidiaries of non-
    Danish or non-Greenlandic companies from competing for the Thule Base Maintenance
    Contract under the current considered Solicitation No. FA2523-21-R-0001. See
    Sumitomo Shoji Am., Inc. v. Avagliano, 
    457 U.S. at 183-85
    ; Factor v. Laubenheimer, 
    290 U.S. at 294-95

    ; Coplin v. United States, 
    761 F.2d at 691

    Defendant also asked the court to consider when interpreting the term
    “Danish/Greenlandic sources” the deference which courts should afford to the
    interpretations of treaties and international agreements and the role in international
    relations of the Executive Branch. (citing RESTATEMENT (FOURTH) OF FOREIGN RELATIONS
    LAW § 306(6)). Protestor, however, responded, relying on National Westminster Bank,
    PLC v. United States, 
    512 F.3d at 1358-59
    , to argue for a lack of deference on the
    58 The 2009 Agreement, as described above, effects an amendment to the 1991
    Memorandum of Understanding, and is more limited in scope than the 1951 Agreement,
    the 1991 Memorandum of Understanding, or the 2004 Agreement. Nevertheless, the
    2009 Agreement represents a continuation of the cooperative framework between the
    United States and Denmark due to the 2009 Agreement’s origin in an exchange of
    diplomatic notes in July 2008 and January 2009.
    59 The court’s conclusion that Diplomatic Note No. 127 gives effect to the United States
    and the Kingdom of Denmark’s shared interpretation of the term “Danish/Greenlandic
    sources” in the 2009 Agreement is bolstered by the statement of Contracting Officer King,
    in the February 16, 2022 IACR (International Agreement Competitive Restrictions)
    document that Diplomatic Note No. 127 is one of “numerous administrative Arrangements
    and supplemental agreements pertaining to the very specific issues” of the United States’
    military presence in Greenland. While the Administrative Record in the above captioned
    bid protest indicates that the IACR was dated after protestor Vectrus had filed its protest
    of Solicitation No. FA2523-21-R-0001 at the GAO, the Contracting Officer stated that
    Diplomatic Note No. 127 is one of “numerous administrative Arrangements” which reflects
    a mutual understanding, including by the United States, that engagement between the
    United States and the Kingdom of Denmark to settle issues such as eligibility criteria for
    contracts to be performed at Thule Air Base, rather than necessitating a new international
    agreement or treaty, and that such developments and changes would be routine or
    “administrative,” consistent with the collaborative framework established by the 1951
    Agreement and expanded upon by the 1991 Memorandum of Understanding, the 2004
    Agreement, and the 2009 Agreement.
    126
    reiterated grounds of inconsistency, “the amended MOU’s plain text,” and the temporal
    relationship between the 2009 Agreement and Diplomatic Note No. 127. The United
    States Supreme Court has held that “[a]lthough not conclusive, the meaning attributed to
    treaty provisions by the Government agencies charged with their negotiation and
    enforcement is entitled to great weight.” Sumitomo Shoji Am., Inc. v. Avagliano, 
    457 U.S. at 184-85
     (alteration added). The Federal Circuit, however, has explained that “an
    agency’s position merits less deference ‘where an agency and another country disagree
    on the meaning of a treaty.’” Nat’l Westminster Bank, PLC v. United States, 
    512 F.3d at 1358
     (quoting Iceland S. S. Co., Ltd.-Eimskip v. United States Dep’t of Army, 
    201 F.3d 451
    , 458 (D.C. Cir. 2000)). In the protest currently before the court, there does not appear
    to be any disagreement between the United States and the Kingdom of Denmark
    regarding the interpretation of “Danish/Greenlandic sources,” and the interpretation “has
    gone unchallenged by” both signatory countries. See O’Connor v. United States, 
    479 U.S. at 33
    . As explained above, the documents contained in the Administrative Record indicate
    that the interpretation of “Danish/Greenlandic sources” to establish which entities are
    eligible to bid on contracts to be performed at Thule Air Base, and to restrict the presence
    of foreign-owned companies or their subsidiaries, was expressly agreed to by the United
    States in deference to the specifically expressed requirements indicated in
    correspondence with the Kingdom of Denmark. Accordingly, the interpretation of
    “Danish/Greenlandic sources” on which the United States and Denmark clearly agree
    based on the record should be afforded great weight in the case currently before this
    court. See Nat’l Westminster Bank, PLC v. United States, 
    512 F.3d at 1358
    .
    In addition to the court’s holding that “Danish/Greenlandic sources” in the 2009
    Agreement can reliably be understood to allow for the exclusion of subsidiaries of foreign
    companies from the Solicitation currently at issue before the this court, according to the
    intent of the United States and the Kingdom of Denmark, the court notes that domestic
    preference statutes and regulations also exist in the United States public procurement
    sphere. Among numerous examples, the Buy American Act, 
    41 U.S.C. § 8301
     et seq.
    (2018), has been described by the United States Court of Appeals for the Federal Circuit
    in the context of construction contracting as having “long required in express terms that
    every construction contract for public buildings and works ‘shall contain a provision that
    in the performance of the work’ only American materials will be used.” S.J. Amoroso
    Constr. Co., Inc. v. United States, 
    12 F.3d 1072
    , 1075 (Fed. Cir. 1993) (quoting 41 U.S.C.
    § 10b (1988)); see also John C. Grimberg Co., Inc. v. United States, 
    869 F.2d 1475
    , 1477
    (Fed. Cir. 1989) (“The BAA [Buy American Act] primarily provides a competitive
    preference to domestic materials in awarding government contracts.” (alteration added)
    (citing Linda Louis Watkins, Effects of the Buy American Act on Federal Procurement, 31
    Fed. B.J. 191, 194 (1972))); Acetris Health, LLC v. United States, 
    138 Fed. Cl. 43
    , 48
    (2018) (explaining that “the Buy American Act restricts the goods that can be acquired by
    the federal government,” citing 
    41 U.S.C. § 8302
    (a), but that “[t]he Trade Agreements Act
    allows the federal government to waive the Buy American statute,” citing 
    19 U.S.C. § 2511
    (a)). Similarly, the Jones Act also provides an example of domestic preference which
    may impact public procurement, and which the United States Court of Federal Claims has
    described as requiring that ships “must be owned and crewed by United States citizens
    and built in the United States,” and “[c]itizens must own at least seventy-five percent of
    127
    the corporation” when the Jones Act applies. See OSG Product Tankers LLC v. United
    States, 
    82 Fed. Cl. 570
    , 572 (2008) (alteration added) (citing 
    46 U.S.C. §§ 50501
    , 55102
    (2006)). Moreover, the United States and the Kingdom of Denmark have agreed to the
    Danish terms for contracting to support Thule Air Base, in accordance with the evolving
    relationship between the United States and Denmark, founded upon the 1951 Agreement.
    In addition to contesting the interplay of the international agreements discussed
    above and the relationship between the United States and the Kingdom Denmark in the
    above captioned bid protest, the parties offered a number of other arguments in support
    of their positions. To support its arguments that the challenged eligibility criteria are not
    required by the phrase “Danish/Greenlandic sources” in the 2009 Agreement, protestor
    also made three inter-related arguments which focus on the government’s conduct prior
    to the issuance of the Solicitation at issue in the above captioned bid protest. First,
    protestor quoted at length from the United States’ cross-motion for judgment on the
    Administrative Record and from an exchange during oral argument in the 2015 Per
    Aarsleff bid protest litigation also before the Court of Federal Claims to defend the
    previous award of the earlier contract to protestor, then operating as Exelis. These quotes
    in the filings before this court in the earlier Per Aarsleff litigation include language such
    as that “‘[t]here is nothing in the plain language of the 1991 MOU, as amended, that
    prohibits Exelis from being considered a “Danish/Greenlandic source,”’” and that
    “‘[n]othing in the language of the 1991 MOU, as amended, indicates that Danish
    limited companies that are owned by United States companies are not
    ‘Danish/Greenlandic sources.’”60 (emphasis in original; alterations added). Although a
    possible inconsistency in the position of the defendant United States between its
    statements in the Per Aarsleff case and the current protest was offered in support by
    protestor to undermine defendant’s position in the current litigation, not only do
    circumstances change, but so too can the analysis of successive courts, especially when
    new information and considerations are at issue.
    Second, protestor argued that “Vectrus would not have won the incumbent Thule
    BMC,” and “the United States’ multiple representations to this Court and the Federal
    Circuit in 2015 and 2016 would have been inaccurate,” if the challenged eligibility criteria
    were required by the term “Danish/Greenlandic sources.” According to protestor, its
    incumbency, along with the strong performance reviews it has received, “reflect that no
    legal impediment has existed to prohibit Vectrus from performing the incumbent contract’s
    requirements, which are materially the same as those being recompeted in this
    procurement.” Protestor also argued that defendant “fails to explain” the change in the
    definition of “Danish/Greenlandic sources” which led to the eligibility criteria in the
    60 Protestor claimed that “the Federal Circuit rejected arguments that award to Exelis was
    improper under the terms of the Predecessor Solicitation merely because Exelis was a
    Danish-registered, wholly-owned subsidiary of a United States-based company.” The
    Federal Circuit in Per Aarsleff in its 2016 opinion, however, did not interpret the language
    of the 2009 Agreement or Exelis’ qualification thereunder, despite protestor’s repeated
    attempts to characterize the Federal Circuit’s opinion as having done so. See Per Aarsleff
    A/S v. United States, 
    829 F.3d at 1311-12
    .
    128
    Solicitation which exclude non-Danish and non-Greenlandic owned and controlled
    companies from competing for the Solicitation, and protestor argued that “[t]he failure to
    acknowledge any change in course violated the APA’s procedural requirements.”
    (alteration added). Protestor alleged in its complaint that the current eligibility criteria
    “contradict the United States’ previous interpretation of the 1991 MOU, as amended in
    2009, that the Thule BMC service provider could be a Danish-registered and United
    States-owned corporation.” Moreover, protestor alleged, without support in the
    Administrative Record before the court and in an attempt to rely on evidence from outside
    the Administrative Record, that the United States, in the time since Diplomatic Note No.
    127, “has repeatedly solicited from and awarded to companies that are neither Danish
    nor Greenlandic owned to provide goods and services in Greenland.” Protestor claims to
    have obtained documentation of these claims from “the System for Award Management
    (‘SAM’) at www.sam.gov and the Federal Procurement Data System (‘FPDS’) at
    www.fpds.gov.” (emphasis in original). Although certain of the contract documents upon
    which defendant attempts to rely concern work to be performed at Thule Air Base, these
    contract solicitation and award documents are unrelated to the Solicitation currently at
    issue in this bid protest, and, therefore, are not in the Administrative Record before the
    court and are not dispositive in this protest concerning the Base Maintenance Contract at
    Thule Air Base.
    Third, protestor argued that both of the Air Force’s October 2016 legal analyses,
    in which the Air Force attempted to explain why draft eligibility criteria proposed by
    Denmark was rejected by the Air Force, are evidence that the challenged eligibility criteria
    in the Solicitation are not a required interpretation of the phrase “Danish/Greenlandic
    source.” Protestor argued that the Competition in Contracting Act and the Air Force’s legal
    analyses “foreclose[]” the argument “that the 2020 diplomatic correspondence ‘refined’
    their [the United States and Denmark’s] interpretation of the amended MOU.” (alterations
    added). Defendant responded that protestor’s focus on the government’s prior arguments
    in the Per Aarsleff litigation “ignores the recent negotiations that led to the interpretation
    at issue” embodied in Diplomatic Note No. 127, and defendant argued that “[i]t defies
    logic” to consider the United States’ arguments in the 2015 Per Aarsleff litigation as an
    admission “regarding the 2020 bilateral discussions interpreting the [1991] MOU.”
    (emphasis in original; alterations added). Defendant further responded that there is no
    “merit to Vectrus’s assertion that its incumbent status indicates that CICA’s international
    agreement exception is inapplicable.” Moreover, defendant argued that the October 2016
    Air Force legal analyses, responding to draft eligibility criteria proposed by Denmark, cited
    by protestor, rejected different eligibility criteria than the criteria at issue in the above
    captioned bid protest, which would have been more restrictive than the criteria at issue in
    the case before this court, and this rejection, according to defendant, reflects the United
    States government’s commitment to maximizing competition. Additionally, the legal
    analyses which protestor attempted to use in support of its position are only the offered
    opinions of the Deputy General Counsel, Acquisition of the Air Force Office of the General
    Counsel, and is not automatically the position of the Department of Justice, which has the
    authority to litigate on behalf of the United States.
    129
    The court has determined that the phrase “Danish/Greenlandic sources” in the
    2009 Agreement can be read to exclude subsidiaries of foreign companies, consistent
    with the United States and Denmark’s intent based on the 1951 Agreement and
    subsequent agreements, including the 1991 Memorandum of Understanding, the 2004
    Agreement, and the 2009 Agreement, and based on further and ongoing diplomatic
    consultations between the United States and Denmark, including Diplomatic Note No.
    127. As discussed above, the court’s role is to interpret “the terms of an international
    agreement,” 
    10 U.S.C.A. § 3204
    (a)(4), “in a manner consistent with the shared
    expectations of the contracting parties.” Lozano v. Montoya Alvarez, 
    572 U.S. at 12
    (emphasis in original) (internal quotations omitted). Protestor’s arguments on these points
    could suggest that the United States may have taken an inconsistent approach to the
    implementation of the terms “Danish/Greenlandic sources” in the earlier Thule Air Base
    procurement in which the Base Maintenance Contract was awarded to Exelis, now
    Vectrus, and that an attorney in the Air Force Office of the General Counsel expressed a
    particular opinion with respect to a different set of potential eligibility criteria proposed by
    the Danish government, but not accepted by the United States. The executive branch
    decision makers responsible for international relationships considered and appear to
    have chosen a different path based on the ongoing and continuous diplomatic
    consultations which started in the Administrative Record before the court with the 1951
    Agreement and resulted in Diplomatic Note No. 127 prior to the Solicitation at issue in the
    current protest under review.
    For the above stated reasons, the court concludes that the language of the 1951
    Agreement, the 1991 Memorandum of Understanding, the 2004 Agreement, and the 2009
    Agreement expressed the intent of both nations that the United States and the Kingdom
    of Denmark would engage in a consultative process regarding their relationship
    throughout the United States’ military presence in Greenland, including at Thule Air Base.
    Consistent with this mutual intent, the United States and the Kingdom of Denmark
    continued to engage in ongoing communications to reach agreement on issues arising
    during their relationship, including the meaning of the 2009 Agreement’s terms directing
    the United States and Denmark to “procure directly from Danish/Greenlandic sources,”
    which the United States and Denmark defined in Diplomatic Note No. 127 to exclude
    subsidiaries of foreign companies from competition for the Thule Air Base Maintenance
    Contract. Accordingly, defendant’s inclusion of the challenged eligibility criteria in the
    currently protested Solicitation, resulting in the exclusion of protestor Vectrus from
    competition under the Solicitation, was lawful and not arbitrary or capricious.
    CONCLUSION
    In sum, the court finds it has subject matter jurisdiction to consider the above
    captioned bid protest, and as discussed above, defendant’s motion to dismiss protestor’s
    complaint is DENIED. Also for the reasons discussed above, protestor’s motion for
    judgment on the Administrative Record is DENIED, and defendant’s cross-motion for
    130
    judgment on the Administrative Record is GRANTED. The Clerk of the Court is directed
    to enter JUDGMENT consistent with this Opinion.
    IT IS SO ORDERED.
