    v.
    BUREAU OF PARKS AND LANDS et al.
    STANFILL, C.J.
    [¶1] The New England Clean Energy Connect project (the Project) is
    designed to transmit power generated in Québec through Maine and into
    Massachusetts. The Project includes a new 145.3-mile, high-voltage direct
    current (HVDC) transmission line, proposed to run from the Maine-Québec
    border in Beattie Township to a new converter station in Lewiston and from
    there to an existing substation by a new 1.2-mile, high-voltage alternating
    current transmission line.            Of the Project’s five segments, segment 1—a
    53.1 mile-long HVDC transmission line running along a corridor from
    Beattie Township to the Forks Plantation—is the most controversial because it

    must be cut through commercial timberland and will cross hundreds of
    wetlands, waterways, and other wildlife habitats, as well as public land.
    [¶2] On November 2, 2021, fifty-nine percent of Maine voters approved
    the following ballot question through a public referendum:
    Do you want to ban the construction of high-impact electric
    transmission lines in the Upper Kennebec Region and to require
    the Legislature to approve all other such projects anywhere in
    Maine, both retroactively to 2020, and to require the Legislature,
    retroactively to 2014, to approve by a two-thirds vote such projects
    using public land?[1]
    Though the question did not mention the Project, the legislation enacted by the
    voters (the Initiative) effectively precludes the Project.2
    [¶3] On November 3, 2021, NECEC Transmission LLC and Avangrid
    Networks, Inc. (collectively, NECEC),3 filed a complaint for declaratory
    1 Section 4 of the Initiative requires legislative approval of the construction of any high-impact
    transmission line in addition to a CPCN from the PUC. I.B. 2021, ch. 1, § 4 (effective Dec. 19, 2021).
    Section 5 of the Initiative bans the construction of any high-impact transmission line in the
    “Upper Kennebec Region,” defined as “the approximately 43,300 acres of land located between the
    Town of Bingham and Wyman Lake, north along the Old Canada Road, Route 201, to the Canadian
    border, and eastward from the Town of Jackman to encompass Long Pond and westward to the
    Canadian border, in Somerset County and Franklin County.” I.B. 2021, ch. 1, § 5 (effective Dec. 19,
    2021). Section 6 requires sections 4 and 5 to be applied retroactively to September 16, 2020. I.B.
    2021, ch. 1, § 6 (effective Dec. 19, 2021).
    2Consistent with the terminology used by the trial court and the parties, we use “the Initiative”
    throughout this opinion to refer to the legislation enacted by the passage of the citizens’ initiative
    question in November 2021. See I.B. 2021, ch. 1, §§ 1-6 (effective Dec. 19, 2021). The Initiative was
    the second attempt at a citizens’ initiative to curtail the Project; we held the first proposed initiative
    unconstitutional in Avangrid Networks, Inc. v. Sec’y of State, 
    2020 ME 109
    , ¶¶ 35-38, 
    237 A.3d 882

    judgment in the Superior Court alleging, among other things, that retroactive
    application of the Initiative to the Project, as required by section 6, is
    unconstitutional on a variety of grounds. The complaint named the Bureau of
    Parks and Lands, the Public Utilities Commission (PUC), the Maine Senate, and
    the Maine House of Representatives as defendants (collectively, the State
    parties). Thirteen organizations and individuals were granted intervenor
    status in the trial court.4
    [¶4] NECEC moved to preliminarily enjoin the Initiative from becoming
    law. After transfer to the Business and Consumer Docket, and following the
    denial of NECEC’s request for a preliminary injunction, the trial court (Duddy, J.)
    reported the case to us pursuant to M.R. App. P. 24(c). We accept the report and
    frame the question of law raised by the court’s reported interlocutory ruling as
    follows:
    Services (U.S.) Inc., originally entered into transmission services agreements with several
    Massachusetts electricity distribution companies to transmit electricity through the Project. CMP
    ultimately transferred all of its rights and responsibilities in the Project to NECEC Transmission LLC.
    4  The following parties intervened on the side of NECEC: H.Q. Energy Services (U.S.) Inc.,
    Cianbro Corporation, International Brotherhood of Electrical Workers Local 104, Industrial Energy
    Consumer Group, and the Maine State Chamber of Commerce. The following parties intervened on
    the side of the State appellees: NextEra Energy Resources, LLC (NextEra); the Natural Resources
    Council of Maine (NRCM); and individuals Thomas B. Saviello, Christine M. Geisser, Wendy A. Huish,
    Jonathan T. Hall, Theresa E. York, and Robert C. Yorks (the West Forks residents).

    Would retroactively applying sections 4 and 5 of the
    Initiative to the certificate of public convenience and
    necessity (CPCN) issued for the Project, as required by
    section 6, violate due process under the Maine Constitution,
    Me. Const. art. I, § 6-A, if NECEC undertook substantial
    construction consistent with and in good-faith reliance on
    the CPCN before the Initiative was enacted?
    Answering that question, we hold that section 6 of the Initiative is
    unconstitutional to the extent it requires sections 4 and 5 to be applied
    retroactively to the CPCN if the appellants have acquired vested rights to
    proceed with Project construction. We therefore remand to the Business and
    Consumer Docket for further proceedings consistent with this opinion.
    I. BACKGROUND
    [¶5] The interlocutory ruling underlying this case is before us pursuant
    to M.R. App. P. 24(c), on report from the Business and Consumer Docket. Given
    that procedural posture, the following facts are taken from the reported ruling
    and our opinion affirming the PUC’s order granting the CPCN for the Project,
    NextEra Energy Res., LLC v. Me. PUC, 
    2020 ME 34

    227 A.3d 1117
    , and are limited
    to those facts relevant to the question of law that we now answer.

     (outlining the limited scope of review for reported interlocutory rulings).

    A.      Project Permitting and Other Governmental Approvals
    [¶6] On September 27, 2017, CMP filed a petition with the PUC to obtain
    a CPCN for the Project. NextEra Energy Res., LLC, 
    2020 ME 34
    , ¶ 3, 
    227 A.3d 1117
    .    The PUC held many days of public and evidentiary hearings and
    conferences and received well over one thousand public comments regarding
    CMP’s petition. Id. ¶ 6. On May 3, 2019, the PUC concluded that the Project
    meets the statutory public-need standard and unanimously voted to grant CMP
    a CPCN to construct and operate the Project, all at no cost to Maine electricity
    customers. Id. ¶¶ 6-10.
    [¶7] Appellee-Intervenor NextEra intervened in the PUC proceeding and
    appealed to us from the order granting the CPCN. Id. ¶¶ 5, 11. We affirmed the
    PUC’s decision on March 17, 2020, concluding that the PUC’s determination,
    findings of fact, and application of the law were supported by the voluminous
    record. Id. ¶ 43.
    [¶8]   In addition to the CPCN, NECEC and CMP obtained multiple
    authorizations      from   various   government   entities   before   beginning
    construction on the Project. NECEC applied for permits from the Department
    of Environmental Protection (DEP) as required under the Natural Resources
    Protection Act, 38 M.R.S. §§ 480-A to 480-JJ (2017), and the Site Location of
    6
    Development Act, 38 M.R.S. §§ 483-A, 484, 487-A (2017), as well as for a
    Site Law Certification from the Land Use Planning Commission (LUPC), see
    12 M.R.S. § 685-B (2017). On May 11, 2020, the DEP approved NECEC’s permit
    application in an order that also incorporated the LUPC’s certification.
    Appellees-Intervenors NextEra, NRCM, and the West Forks residents appealed
    the DEP’s order to the Superior Court and the Board of Environmental
    Protection (BEP) and moved to stay the order. The Superior Court denied their
    motion to stay the DEP’s order. NextEra Energy Res., LLC v. Dep’t of Env’t Prot.,
    
    2021 Me. Super. LEXIS 14
     (Jan. 8, 2021). On November 23, 2021, the DEP
    suspended the permit it had issued pending the outcome of this case. The
    appeal to the BEP remained pending when this case was filed in the
    Superior Court.5
    [¶9] NECEC and CMP also secured a permit from the United States Army
    Corps of Engineers under the Clean Water Act and the Rivers & Harbors Act
    (the ACE permit). See 
    33 U.S.C.S. § 1344
     (LEXIS through Pub. L. No. 117-66);
    
    33 U.S.C.S. § 403
     (LEXIS through Pub. L. No. 117-116). The Sierra Club, NRCM,

    pending, but that information is not part of the formal record before us. See, e.g., Edward D. Murphy,

    2022), https://www.pressherald.com/2022/07/21/state-environmental-board-denies-appeal-of-
    transmission-line-project/.

    and the Appalachian Mountain Club (AMC) sued the Army Corps of Engineers
    to enjoin the ACE permit, alleging that the environmental assessment
    underlying the permit was insufficient and that the Corps should have instead
    completed a full environmental impact statement. Following an emergency
    appeal of the denial of a preliminary injunction, on January 15, 2021, the
    United States Court of Appeals for the First Circuit enjoined construction on
    segment 1 of the Project pending appeal. The First Circuit vacated the partial
    injunction on May 13, 2021, Sierra Club v. U.S. Army Corps of Eng’rs, 
    997 F.3d 395
     (1st Cir. 2021), but the case remains pending.
    [¶10]     Separately, CMP received a presidential permit from the
    United States   Department     of   Energy   (DOE)    on   January   14,   2021.
    NECEC Transmission LLC, DOE Docket No. PP-438, Presidential Permit (DOE
    Jan. 14, 2021); see Exec. Order No. 10,485, 3 C.F.R. 106 (1953), amended by
    Exec. Order No. 12,038, 3 C.F.R. 136 (1978). Thereafter, the Sierra Club, NRCM,
    and AMC amended their pending complaint regarding the ACE permit to
    include claims relating to the presidential permit.
    [¶11]     Finally, NECEC obtained municipal permits and approvals
    requiring compliance with local rules in most municipalities through which the
    8
    Project will pass. At the time this case was filed, NECEC had not yet secured
    permits and approvals from four municipalities.
    [¶12] In addition to the aforementioned permits and approvals, NECEC
    (through CMP) needed a lease from the Bureau of Parks and Lands for the
    0.9-mile stretch of the Project that crosses public reserved lands in
    Johnson Mountain Township and West Forks Plantation. In 2014, CMP had
    obtained a lease from the Bureau to construct electric transmission facilities,
    and in 2020 CMP entered into an amended lease (the BPL lease) superseding
    the 2014 lease for the public reserved lands through which the Project would
    pass.6
    [¶13] In June 2020, Senator Russell Black filed a complaint in the
    Superior Court against the Bureau, alleging the BPL lease violated article IX,
    section 23 of the Maine Constitution. The Business and Consumer Docket
    (Murphy, J.) vacated the BPL lease, Black v. Cutko, No. BCDWB-CV-2020-29,
    
    2021 WL 3700685
     (Me. B.C.D. Aug. 10, 2021), and that decision was appealed
    to us, Black et al. v. Bureau of Parks and Lands et al., No. BCD-21-257. After
    Senator Black moved to lift the automatic stay on the judgment, we issued an
    agreed-upon order prohibiting NECEC from building on the leased
    6   CMP assigned its interest in the 2020 BPL lease to NECEC Transmission LLC on January 4, 2021.
    9
    public reserved lands until the legal questions regarding the BPL lease have
    been resolved. See M.R. Civ. P. 62(e), (g).
    [¶14] In summary, at the time this case was filed, (1) the DEP permit
    (incorporating the LUPC Site Law certificate) was still pending on appeal before
    the BEP, (2) the ACE permit and the presidential permit from the DOE were the
    subjects of a lawsuit in federal court, (3) the BPL lease was the subject of a
    direct appeal to us in another case, and (4) not all necessary municipal
    approvals had been obtained. The only Project-wide permit or approval that
    was final when this case was filed was the CPCN from the PUC—an order that
    we affirmed and that is not subject to any further review.
    B.    Project Construction
    [¶15] The Project is divided into five segments. Segment 1 includes
    53.1 miles of HVDC line along a new corridor running from Beattie Township
    at the Canadian border to the Forks Plantation. Segments 2 and 3 cover
    approximately 92 miles of transmission line along an existing corridor that will
    be widened.    Segments 4 and 5 focus on network upgrades, including a
    26.5-mile transmission line from Lewiston to Wiscasset.
    [¶16] NECEC received the final Project-wide permit—the presidential
    permit from the DOE—on January 14, 2021. On January 18, 2021, NECEC
    10
    started clearing and construction activities in segments 2 through 5 of the
    Project. On May 15, 2021, NECEC commenced construction on segment 1 of the
    Project, the 53.1 miles from the Canadian border to the Forks Plantation.
    [¶17] According to the preliminary injunction record, NECEC had spent
    nearly $450 million on the Project, approximately forty-three percent of the
    projected total cost, as of November 3, 2021, when this case was filed in the
    Business and Consumer Docket. Between January 18, 2021, and the time the
    Project was halted following the referendum in November 2021, NECEC cut
    approximately 124 miles of right-of-way for direct current lines, cleared the
    entire corridor for the alternating current line, erected transmission structures
    along the corridor, and prepared the converter station site.
    C.    The 2021 Citizens’ Initiative
    [¶18] As we recently reiterated in connection with a related citizens’
    initiative:
    The broad purpose of the direct initiative is the encouragement of
    participatory democracy. By [article IV, part third,] section 18 [of
    the Maine Constitution,] the people, as sovereign, have retaken
    unto themselves legislative power, and that constitutional
    provision must be liberally construed to facilitate, rather than to
    handicap, the people’s exercise of their sovereign power to
    legislate. . . . [S]ection 18 cannot be said merely to permit the direct
    initiative of legislation upon certain conditions. Rather, it reserves
    to the people the right to legislate by direct initiative if the
    constitutional conditions are satisfied.

    Sec’y of State, 
    2006 ME 50
    , ¶ 25, 
    896 A.2d 933
    ).
    [¶19] In accordance with the Maine Constitution’s provision for direct
    initiative of legislation, Me. Const. art. IV, pt. 3, § 18, voters circulated a petition
    for a citizens’ initiative affecting the Project beginning on October 30, 2020. On
    February 22, 2021, the Secretary of State determined that the petition had
    garnered enough valid signatures to present the initiated bill to the Legislature.
    See id. § 18(2); 21-A M.R.S. § 905(1) (2022). Though presented with the bill,
    L.D. 1295 (130th Legis. 2021), the Legislature did not act on the measure before
    adjourning sine die on March 30, 2021. See Me. Const. art. IV, pt. 3, § 18(2). As
    a result, a ballot question summarizing the initiated bill was submitted to the
    public for a vote in November 2021. See id. § 18(2)-(3); see generally Caiazzo v.
    Sec’y of State, 
    2021 ME 42
    , ¶¶ 2-5, 
    256 A.3d 260
    .
    [¶20] On November 2, 2021, fifty-nine percent of Maine voters approved
    the initiated bill, which took effect on December 19, 2021, and effectively halted
    the Project. The legislation enacted through the Initiative consists of six
    sections, four of which effect statutory changes with implications for the
    Project.7 I.B. 2021, ch. 1, §§ 1-6 (effective Dec. 19, 2021). We do not address
    7  NECEC argues that the sections of the Initiative are not severable and therefore the entire
    Initiative must fall if we conclude that any section is unconstitutional. However, we need not consider
    12
    sections 2 and 3 of the Initiative because no one challenges their
    constitutionality.
    [¶21] Section 1 of the Initiative amends 12 M.R.S. § 1852 (2021), which
    governs the Bureau’s authority to lease public reserved lands, by requiring
    legislative approval for leases for transmission lines retroactively to
    September 16, 2014. I.B. 2021, ch. 1, § 1 (effective Dec. 19, 2021). The effect of
    section 1 upon the portion of the Project involving public reserved land is the
    subject of the separate appeal in Black et al. v. Bureau of Parks and Lands et al.,
    No. BCD-21-257, and is more appropriately addressed in that context rather
    than on report under M.R. App. P. 24(c). See Littlebrook Airpark Condo. Ass’n,
    
    2013 ME 89
    , ¶ 9, 
    81 A.3d 348
    .
    [¶22] Sections 4, 5, and 6 of the Initiative amend 35-A M.R.S. § 3132
    (2021), the statute requiring project developers to obtain a CPCN from the PUC
    before constructing certain transmission lines. I.B. 2021, ch. 1, §§ 4-6 (effective
    the issue of severability because the parties failed to preserve it in the trial court. MP Assocs. v.
    Liberty, 
    2001 ME 22
    , ¶ 18, 
    771 A.2d 1040
    . Even if the issue were preserved, the separate sections of
    the Initiative would be severable. See 1 M.R.S. § 71(8) (2022) (codifying the general rule of statutory
    construction that “[t]he provisions of the statutes are severable”); Lambert v. Wentworth, 
    423 A.2d 527
    , 535 (Me. 1980) (establishing the presumption of severability in statutes whose unconstitutional
    provisions are separate and independent from the valid provisions); see also 16A Am. Jur. 2d
    Constitutional Law § 211 (“[I]f a statute is unconstitutional as applied, the state may continue to
    enforce that statute in different circumstances where it is not unconstitutional, and if a statute has
    unconstitutional applications, they are severable from the constitutional applications.” (footnotes
    omitted)).

    Dec. 19, 2021). Those sections do not affect the authority of any executive
    agency other than the PUC, nor do they affect any of the many permits or
    approvals obtained by the Project except the CPCN.
    [¶23] Section 4 of the Initiative enacts 35-A M.R.S. § 3132(6-C) (2022)8
    and provides that “[i]n addition to obtaining a [CPCN], a high-impact electric
    transmission line may not be constructed anywhere in the State without first
    obtaining the approval of the Legislature.” I.B. 2021, ch. 1, § 4 (effective Dec. 19,
    2021). Section 5 of the Initiative enacts 35-A M.R.S. § 3132(6-D) (2022),9 which
    8   Section 4 states in full as follows:
    Sec. 4. 35-A MRSA §3132, sub-§6-C is enacted to read:
    6-C. High-impact electric transmission line; legislative approval. In addition
    to obtaining a certificate of public convenience and necessity, a high-impact electric
    transmission line may not be constructed anywhere in the State without first
    obtaining the approval of the Legislature, except that any high-impact electric
    transmission line crossing or utilizing public lands designated by the Legislature
    pursuant to Title 12, section 598-A is deemed to substantially alter the land and must
    be approved by the vote of 2/3 of all the members elected to each House of the
    Legislature.
    I.B. 2021, ch. 1, § 4 (effective Dec. 19, 2021).
    9   Section 5 states in full as follows:
    Sec. 5. 35-A MRSA §3132, sub-§6-D is enacted to read:
    6-D. High-impact electric transmission line; geographic prohibition.
    Notwithstanding subsection 6-C, a high-impact electric transmission line may not be
    constructed in the Upper Kennebec Region. For the purpose of this subsection,
    “Upper Kennebec Region” means the approximately 43,300 acres of land located
    between the Town of Bingham and Wyman Lake, north along the Old Canada Road,
    Route 201, to the Canadian border, and eastward from the Town of Jackman to
    encompass Long Pond and westward to the Canadian border, in Somerset County and
    Franklin County.
    14
    bans all high-impact electric transmission lines from the “Upper Kennebec
    Region,” an area spanning portions of Franklin and Somerset Counties. I.B.
    2021, ch. 1, § 5 (effective Dec. 19, 2021). Finally, section 6 of the Initiative
    enacts 35-A M.R.S. § 3132 (6-E) (2022),10 which applies sections 4 and 5
    retroactively to high-impact electric transmission line projects on which
    construction had not started by September 16, 2020. I.B. 2021, ch. 1, § 6
    (effective Dec. 19, 2021). Though the Initiative does not expressly mention the
    Project, sections 4 and 5 apply to the Project through section 6 because
    construction did not begin on it until January 2021.
    D.          Procedural History
    [¶24] On November 3, 2021, the day after the public referendum on the
    initiated bill, NECEC (i.e., NECEC Transmission LLC and Avangrid) filed a
    three-count verified complaint against the State parties seeking declaratory
    I.B. 2021, ch. 1, § 5 (effective Dec. 19, 2021).
    10   Section 6 states in full as follows:
    Sec. 6. 35-A MRSA §3132, sub-§6-E is enacted to read:
    6-E. Retroactivity. Notwithstanding Title 1, section 302 or any other provision of
    law to the contrary, subsections 6-C and 6-D apply retroactively to September 16,
    2020 and apply to any high-impact electric transmission line the construction of
    which had not commenced as of that date.
    I.B. 2021, ch. 1, § 6 (effective Dec. 19, 2021).
    15
    and injunctive relief to permanently block retroactive application of the
    Initiative to the Project. That same day, NECEC moved for a preliminary
    injunction to stay the initiated legislation during the pendency of the litigation.
    Several organizations and individuals moved to intervene; five supported
    NECEC, and eight supported the State parties. After expedited briefing and
    argument, the Business and Consumer Docket denied NECEC’s motion for a
    preliminary injunction on December 16, 2021.           In a comprehensive and
    thoughtful opinion, the court rejected the various constitutional challenges to
    the initiated legislation and found “no basis to block the Initiative from going
    into effect as scheduled.” However, the court also suggested that NECEC and
    the supporting intervenors move to have the questions of law reported to us
    pursuant to M.R. App. P. 24(c).
    [¶25] On December 22, 2021, NECEC moved for the court to report the
    interlocutory ruling denying its request for a preliminary injunction. M.R. App.
    P. 24(c). Less than a week later, the court reported the case “in its entirety for
    the Law Court to determine the questions of law presented.”

    II. DISCUSSION
    A.        Scope of Appellate Review under Rule 24(c)
    [¶26] Rule 24(c) of the Maine Rules of Appellate Procedure governs
    reported interlocutory rulings and is an exception to the final judgment rule.
    As such, it should be used sparingly, Bank of Am., N.A. v. Cloutier, 
    2013 ME 17
    ,
    ¶ 8, 
    61 A.3d 1242
    , especially to report constitutional questions, Sirois v.
    Winslow, 
    585 A.2d 183
    , 185 (Me. 1991).11 Rule 24(c) provides:
    If the trial court is of the opinion that a question of law involved in
    an interlocutory order or ruling made by it ought to be determined
    by the Law Court before any further proceedings are taken, it may
    on motion of the aggrieved party report the case to the Law Court
    for that purpose and stay all further proceedings except such as are
    necessary to preserve the rights of the parties without making any
    decision therein.
    M.R. App. P. 24(c). Upon receipt of a Rule 24(c) report, our broad task is to
    determine whether accepting the report and answering the questions of law
    therein “‘is consistent with our basic function as an appellate court, or would
    improperly place us in the role of an advisory board.’” Littlebrook Airpark

    Former Rule 72 of the Maine Rules of Civil Procedure governed the process for reporting cases

    72 (West 2001); see M.R. App. P. 1 Advisory Note, Jan. 1, 2001. Because Rule 24 is “derived nearly
    verbatim from former” Rule 72, 3A Harvey & Merritt, Maine Civil Practice § A24:1 at 224 (3d,
    2021-2022 ed. 2021), we consider cases that examined former Rule 72 when interpreting Rule 24.

    ).      We weigh three factors to make that determination:
    “(1) whether ‘the question reported is of sufficient importance and doubt to
    outweigh the policy against piecemeal litigation’; (2) whether ‘the question
    might not have to be decided because of other possible dispositions’; and
    (3) whether ‘a decision on the issue would, in at least one alternative, dispose
    of the action.’” 
    Id.
     (quoting Cloutier, 
    2013 ME 17

    61 A.3d 1242
    ).
    [¶27] Here, the court reported its order denying NECEC’s motion to
    preliminarily enjoin the Initiative “in its entirety” and did not submit specific
    questions. The court’s open-ended report does not prevent us from acting on
    it. See, e.g., Luhr v. Bickford, 
    661 A.2d 1141
    , 1141-42 (Me. 1995) (considering
    whether to accept a report that presented “unspecified questions of law”
    involved in the trial court’s interlocutory order, identifying the operative
    question of law at issue, and discharging the report after concluding that the
    question was not doubtful (quotation marks omitted)); Churchill v. S.A.D. No. 49
    Tchrs. Ass’n, 
    380 A.2d 186
    , 189 (Me. 1977) (“So long as the record clearly
    identifies the issue raised and contains the necessary information to permit a
    determination of the question, no further particularization is required.”); but
    see Swanson v. Roman Cath. Bishop, 
    1997 ME 63
    , 16 & n.11, 
    692 A.2d 441
    (Lipez, J., dissenting) (urging caution when deciding whether to accept a
    18
    reported case involving constitutional questions and noting that Luhr did not
    involve constitutional claims). It does, however, require us to define the scope
    of our review before we reach the merits.
    [¶28] NECEC urges us to accept three questions on report:12
    1)     Whether the Initiative unlawfully deprives NECEC of a vested
    right to complete Project construction;
    2)     Whether the Initiative violates the separation of powers
    under the Maine Constitution; and
    3)     Whether the Initiative unlawfully impairs NECEC’s rights
    under the contracts clauses of the United States and Maine
    constitutions.
    [¶29] We limit our analysis to sections 4 through 6 of the Initiative.
    Section 1 of the Initiative affects the authority of the Bureau to lease
    public reserved lands by retroactively requiring legislative approval for
    transmission line leases. I.B. 2021, ch. 1, § 1 (effective Dec. 19, 2021). The
    Business and Consumer Docket (Murphy, J.) vacated the BPL lease based on a
    determination         that     it    was      not     validly     issued,      Black      v.   Cutko,
    12NECEC argues further that we should address all issues involved in the interlocutory ruling
    including whether NECEC will suffer irreparable harm, whether the balance of harms favors an
    injunction, and whether the public interest favors an injunction. We disagree. Those questions are
    fact-bound and would require this Court to apply the abuse-of-discretion and clear-error standards,
    see All. for Retired Ams. v. Sec’y of State, 
    2020 ME 123
    , ¶ 12, 
    240 A.3d 45
    , which would be inconsistent
    with the de novo review of legal questions to which a Rule 24(c) report is limited. Moreover, the legal
    standards governing the grant or denial of a preliminary injunction can be resolved by applying
    well-established principles of law and, therefore, are not sufficiently doubtful to require our
    attention. Despres v. Moyer, 
    2003 ME 41
    , ¶ 14, 
    827 A.2d 61
    .

    No. BCDWB-CV-2020-29, 
    2021 WL 3700685
     (Me. B.C.D. Aug. 10, 2021), and
    that decision has been appealed to us, Black et al v. Bureau of Parks and Lands
    et al., No. BCD-21-257. The constitutionality of the retroactive clause of
    section 1 of the Initiative, which amends the authority of the Bureau under
    Title 12, may never have to be decided depending on the outcome of that
    appeal.        Under those circumstances, further consideration of the
    constitutionality of section 1 of the Initiative would not be consistent with our
    basic appellate function. See Littlebrook Airpark Condo. Ass’n, 
    2013 ME 89
    , ¶ 9,
    
    81 A.3d 348
    .
    [¶30] The separation of powers claim requires only a brief explanation.
    We have recognized the power of a legislative body to enact retroactive
    legislation that affects the validity of a permit issued by an executive authority.
    See, e.g., City of Portland v. Fisherman’s Wharf Assocs. II, 
    541 A.2d 160
    , 162-64
    (Me. 1988). Neither the CPCN nor any other permit that has been upheld in
    court as validly issued is necessarily categorically exempt from retroactive
    legislation.    However, the effect of retroactive legislation upon existing
    proceedings and rights is ultimately for the courts, not the Legislature, to
    decide. For example, in Avangrid, we declared the citizens’ initiative at issue
    there to be invalid because it purported to adjudicate the validity of the CPCN
    20
    directly, and thereby exercise judicial power rather than legislative power.
    
    2020 ME 109
    , ¶ 35, 
    237 A.3d 882
    .              The Initiative now before us is
    distinguishable because it is an exercise of legislative power that may affect the
    validity of the CPCN but leaves judicial review—and the separation of powers—
    intact.
    [¶31] With respect to the contracts clause claim, we decline to address
    that question because it is governed by established principles of law. See
    Kittery Retail Ventures, LLC v. Town of Kittery, 
    2004 ME 65
    , ¶ 38, 
    856 A.2d 1183
    (reciting the well-settled test for resolving contracts clause claims). In other
    words, the question that the contracts clause claim raises is not sufficiently
    doubtful    “to     outweigh   the   policy    against   piecemeal     litigation.”
    Littlebrook Airpark Condo., Ass’n, 
    2013 ME 89
    , ¶ 9, 
    81 A.3d 348
     (quotation
    marks omitted).
    [¶32]       Thus, we accept and answer only the question whether
    retroactively applying sections 4 and 5 of the Initiative to the CPCN issued for
    the Project, as required by section 6, violates the due process clause of the
    Maine Constitution.
    21
    B.    The vested rights doctrine arises from the Maine Constitution and
    limits the Legislature’s authority to apply laws retroactively.
    [¶33] Whether retroactive application of the Initiative to the CPCN that
    the PUC issued for the Project unconstitutionally impairs NECEC’s vested rights
    depends on whether Maine’s vested rights doctrine is a constitutional
    limitation on legislative authority, including citizen initiatives. We hold that it
    is.
    [¶34] By its terms, the Initiative applies retroactively to the PUC’s
    authority over projects involving high-impact electric transmission lines on
    which construction had not started by September 16, 2020, 35-A M.R.S.
    § 3132(6-E) (2022), and thus it applies to the Project.
    [¶35] The same constitutional limitations on legislative authority apply
    to citizen-initiated legislation as apply to the enactments of the Legislature.
    Opinion of the Justices, 
    2017 ME 100
    , ¶ 59, 
    162 A.3d 188
    . We are mindful that
    citizen-initiated legislation enjoys a “heavy presumption of constitutionality”
    and should be construed liberally. 
    Id.
     (quotation marks omitted). At the same
    time, “[s]ince by the initiative process the people of Maine are exercising their
    legislative power, the constitutional validity of a citizen initiative is evaluated
    under the ordinary rules of statutory construction.” League of Women Voters v.
    Sec’y of State, 
    683 A.2d 769
    , 771 (Me. 1996).
    22
    [¶36] “If the Legislature intends a retroactive application, the statute
    must be so applied unless the Legislature is prohibited from regulating conduct
    in the intended manner, and such a limitation upon the Legislature’s power can
    only arise from the United States Constitution or the Maine Constitution.”
    Norton v. C.P. Blouin, Inc., 
    511 A.2d 1056
    , 1060 n.5 (1985) (emphasis added);
    see State v. L.V.I. Group, 
    1997 ME 25
    , ¶ 9, 
    690 A.2d 960
     (characterizing the cited
    excerpt from Norton as “clarif[ying] the proper analysis concerning the
    retroactive application of statutes”); cf. Opinion of the Justices, 
    103 Me. 506
    , 508,
    
    69 A. 627
     (1907) (“[L]aws and regulations are to be held valid unless there can
    be pointed out some provision in the State or United States Constitution which
    clearly prohibits them.”).
    [¶37] The principal parties accept Norton’s directive but disagree about
    the provenance of Maine’s vested rights doctrine. NECEC argues that the
    doctrine is grounded in the due process clause of the Maine Constitution,
    Me. Const. art. I, § 6-A, and that it therefore limits the Legislature from applying
    the Initiative retroactively. The State appellees contend instead that the vested
    rights doctrine is a creature of common law that citizens, acting as the
    Legislature, may—and did—abrogate by clear enactment.
    23
    1.    The vested rights doctrine and the due process clause of the
    Maine Constitution.
    [¶38] Contrary to the State appellees’ arguments, the protection of
    vested rights has been rooted in the Maine Constitution since Maine became a
    state. See David M. Gold, The Tradition of Substantive Judicial Review: A Case
    Study of Continuity in Constitutional Jurisprudence, 
    52 Me. L. Rev. 355
    , 364-70
    (2000) (chronicling the history of Maine’s vested rights jurisprudence). We
    first considered the legal significance of vested rights just three years after the
    Maine Constitution took effect, in Proprietors of Kennebec Purchase v. Laboree,
    
    2 Me. 275
    , 288-93 (1823). There, we considered the constitutionality of
    retroactively applying a statute changing the doctrine of disseisin that would
    have resulted in a deeded owner losing his land. 
    Id. at 286-93
    . In describing
    the effect of the statute, we discussed article 1, section 1 of the Maine
    Constitution:
    By the spirit and true intent and meaning of this section, every
    citizen has the right of “possessing and protecting property”
    according to the standing laws of the state in force at the time of his
    “acquiring[”] it, and during the time of his continuing to possess it.
    Unless this be the true construction, the section seems to secure no
    other right to the citizen than that of being governed and protected
    in his person and property by the laws of the land, for the time
    being. . . . The design of the framers of our constitution, it would
    seem, was . . . to guard against the retroactive effect of legislation
    upon the property of the citizens.
    24
    
    Id. at 290
     (quoting Me. Const. art. 1, § 1).       We proceeded to hold that
    retroactively applying the challenged statute was unconstitutional to the extent
    that it altered the common law “because such operation would impair and
    destroy vested rights, and deprive the owners of real estate of their titles
    thereto, by changing the principles and the nature of those facts, by means of
    which those titles had existed and been preserved to them in safety.” Id. at
    294-95.
    [¶39]   Since Laboree, we have continued to frame vested rights in
    constitutional terms, albeit broadly and often without reference to any specific
    provision of the Maine Constitution. In Coffin v. Rich, 
    45 Me. 507
    , 514-16
    (1858), we relied on Laboree to hold that a statute making individual
    stockholders personally liable for corporate debts was unconstitutional as
    applied retroactively because it created a new liability where none had
    previously existed. We explained:
    There can be no doubt that Legislatures have the power to pass
    retrospective statutes, if they affect remedies only. Such is the well
    settled law of this State. But they have no constitutional power to
    enact retrospective laws which impair vested rights, or create
    personal liabilities.
    
    Id. at 514-15
    ; see Thut v. Grant, 
    281 A.2d 1
    , 6 (Me. 1971) (“[T]he Legislature has
    full power and authority to regulate and change the form of remedies in actions
    25
    if no vested rights are impaired or personal liabilities created. There is no
    constitutional inhibition against the enactment of retroactive legislation which
    affects remedies only.” (emphasis and quotation marks omitted)). We relied on
    Coffin in Sabasteanski v. Pagurko, 
    232 A.2d 524
    , 525-26 (Me. 1967), where we
    held that a statute validating deeds with certain administrative defects was
    unconstitutional as applied retroactively because it effectively ousted
    subsequent innocent purchasers of their right to property.
    [¶40] In Adams v. Palmer, 
    51 Me. 480
     (1863), we identified a provision
    of the Maine Constitution as protecting vested rights different from the one we
    identified in Laboree. In Adams, a widow had, while she was still a minor,
    released her right of dower to a parcel of land by joining in a deed with her
    husband. 
    Id. at 487
    . Because she was a minor when she signed the deed, the
    deed was voidable by her. 
    Id. at 489
    . After she became an adult, the Legislature
    enacted a statute providing that a minor’s release of a right of dower was valid.
    
    Id. at 490
    . We held the statute was unconstitutional as applied retroactively.
    
    Id.
     We reasoned that the adult widow’s right to recover a freehold estate upon
    her husband’s death was a vested property right. 
    Id.
     We implied that the
    widow’s vested right was protected by the guarantee in article I, section 6 of
    the Maine Constitution “that no one shall ‘be deprived of his life, liberty,
    26
    property, or privileges, but by the judgment of his peers or the laws of the land.’”
    
    Id.
     (quoting Me. Const. art. 1, § 6 (emphasis omitted)).13
    [¶41] Against this historical backdrop, NECEC argues that vested rights
    are properly viewed as arising from the Maine Constitution’s due process
    clause, article I, section 6-A. We agree. Though our decisions in Laboree and
    Adams predate the adoption of section 6-A, see 
    1965 Me. Laws 1163
    (Proclamation of the Governor of Maine), their logic recognizes implied due
    process protections in article I, sections 1 and 6 that guard against retroactivity.
    In Laboree we interpreted section 1 as protecting a person’s inherent right to
    possess and protect property “according to the standing laws of the State in
    force at the time of his acquiring it, and during the time of his continuing to
    possess it.” Laboree, 
    2 Me. at 275, 290
     (quotation marks omitted). The essence
    of that right is due process. Cf. Hammond v. Temp. Comp. Rev. Bd., 
    473 A.2d 1267
    , 1272 (Me. 1984) (observing that a party alleging a due process violation
    13See also Austin v. Stevens, 
    24 Me. 520
    , 529 (1845) (“While the exercise of the legislative power
    is admitted to be both constitutional and expedient, to determine what shall be the respective rights
    and duties of tenants for life, and of reversioners in relation to improvements made during the
    continuance of the estate for life, it will not follow, that their rights to such improvements can be
    altered or changed, after they have been fixed and established by the laws existing at the time, when
    the life estate falls. The right of the legislative department to authorize a person holding lands by
    possession and improvement, to claim and obtain compensation for his improvements has been
    admitted. But if he should voluntarily abandon his improvements with the land, and they should by
    the existing laws, as they would now do, become the property of the owner of the estate, would any
    intelligent person claim for the legislature the constitutional power to deprive the owner of any
    portion of his estate except for public use?”).
    27
    “must be able to point to existing law or rules, or mutual understandings,
    wherein his claims of entitlement are secured and may be supported”);
    Thomas M. Cooley, A Treatise on the Constitutional Limitations Which Rest
    Upon the Legislative Power of the States of the American Union 356 (1868)
    (“Due process of law in each particular case means, such an exertion of the
    powers of government as the settled maxims of law sanction . . . .”);
    cf. Tinkle, The Maine State Constitution 29 (2d ed. 2013) (observing that
    section 1 “has been perceived as a catchall for fundamental rights not otherwise
    enumerated in Article I”). In Adams, we analogized section 6’s protection of
    vested property rights to the due process clause in the New York constitution
    that that state’s high court relied on to reject a retroactive law as
    unconstitutional. See Adams, 
    51 Me. at
    492-93 (citing Westervelt v. Gregg,
    
    12 N.Y. 202
     (1854)).14 Moreover, this court has long equated sections 6’s “law
    of the land” clause with “due process of law.” See, e.g., State v. Knight, 
    43 Me. 11
    ,
    122 (1857) (defining “law of the land” as “the due course and process of law”
    (quotation marks omitted)); State v. Doherty, 
    60 Me. 504
    , 509 (1872) (“‘[D]ue
    process of law’ and ‘law of the land’ have the same meaning.”); Jordan v. Gaines,
    14 Further, Adams characterized our decision in Laboree as approving the due process principles
    upon which other courts had rejected retroactive legislation as “denying the power of the Legislature
    to take away vested rights.” Adams v. Palmer, 
    51 Me. 480
    , 493 (Me. 1863).
    28
    
    136 Me. 291
    , 294, 
    8 A.2d 585
     (1939) (“‘[D]ue process of law’ and ‘the law of the
    land’ are identical in meaning.           They are of equivalent import and
    interchangeable.” (citations omitted)).
    [¶42] Thus, sections 1 and 6 of the Maine Constitution’s Declaration of
    Rights were proxies for due process protections of vested rights until section
    6-A was adopted in 1963. Cf. L.D. 33 (101st Legis. 1963) (“A due process
    clause . . . should be added to the Maine Constitution. . . . It may well be said that
    in various places within the Declaration of Rights, as the same is now written,
    much of the protection given by the proposed new due-process clause appears.
    However, the rights with which we are here concerned are so fundamental and
    so important that if there is a second or repeat guarantee, such underwriting of
    protection is, we believe, all to the good.”). Constitutional protection of vested
    rights properly resides in Maine’s due process clause. Cf. Tinkle, The Maine
    State Constitution 45 (2d ed. 2013) (“With the incorporation into the state
    constitution of section 6-A, which expressly contains a due process clause, the
    law of the land clause [in section 6] has become doubly redundant and fallen
    into desuetude.”) We conclude that the vested rights doctrine “arises from” the
    Maine Constitution such that it constrains the power to enact retroactive
    legislation.
    29
    2.      NECEC’s vested rights claim to develop the Project under
    the terms of the CPCN
    [¶43]    Sections 4 through 6 of the Initiative relate to 35-A M.R.S.
    § 3132(6), which directs the PUC to determine whether a proposed
    transmission line project serves an identified “public need.” I.B. 2021, ch. 1,
    §§ 4-6 (effective Dec. 19, 2021). Section 4 adds a requirement to the statute for
    legislative approval “[i]n addition to obtaining a [CPCN].” Id. § 4. Section 5
    categorically bans construction of high-impact electric transmission projects in
    the “Upper Kennebec Region.” Id. § 5. Section 6 makes sections 4 and 5 of the
    Initiative applicable to all high-impact electric transmission lines on which
    construction had not started by September 16, 2020. Id. § 6. Because NECEC
    started construction on the Project some four months after September 16,
    2020, the retroactivity provision in section 6 directly impairs NECEC’s ability
    to proceed with Project construction pursuant to the terms of the CPCN issued
    under then-existing law.
    [¶44] The issue before us involves the intersection of NECEC’s private
    interest to proceed and the interest of the electorate to determine public
    legislative policy. The applicability of the vested rights doctrine here turns on
    whether NECEC acquired a cognizable property right that the Maine
    Constitution protects from being impaired by retroactive legislation.

    , 455-56 (2008)
    (“‘Vested rights are rights vested in specific individuals in accordance with the
    law in what the law recognizes as property.’ Critical to the application of the
    doctrine of vested rights, then, is a definition of what constitutes
    property. . . . James Madison viewed property as embracing ‘everything to
    which a man may attach a value and have a right.’” (quoting Edward S. Corwin,
    The Basic Doctrine of American Constitutional Law, 
    12 Mich. L. Rev. 247
    , 271
    (1914) (footnotes omitted)).
    [¶45] NECEC urges us to look at the Project as a whole, arguing that it
    has a vested right to complete construction of the entire Project. But the
    question presented in this case and which we proceed to answer is narrower.
    We limit our vested rights analysis to the specific approval that the retroactivity
    provision in section 6 of the Initiative affected. The Initiative retroactively
    imposes a requirement of legislative approval for a CPCN previously granted by
    the PUC. It does nothing to affect the other permits or approvals that NECEC
    needs before it may complete the Project, many of which are still the subject of
    31
    pending proceedings.15 In other words, the focus of a vested rights analysis
    must be upon the specific entitlement that is affected by the retroactively
    applied legislation. Thus, the fact that NECEC had not obtained all required
    municipal permits at the time this case was filed does not bear on whether
    NECEC has acquired a constitutionally protected property right to continue the
    work authorized by the CPCN. Nevertheless, NECEC’s ability to complete the
    entire Project is contingent on obtaining any remaining permits needed,
    assuming that NECEC has, in fact, acquired a vested right to proceed as
    authorized by the CPCN’s terms and conditions.
    [¶46] In Maine and other states, the right to proceed with construction
    in the municipal-law context vests once a developer undertakes significant,
    visible construction in good faith and with the intent to carry construction
    through to completion as authorized by a validly issued building permit. Sahl v.
    Town of York, 
    2000 ME 180
    , ¶ 12, 
    760 A.2d 266
    ; see J. Spencer Hall, State Vested
    Rights Statutes: Developing Certainty and Equity and Protecting the Public
    Interest, 
    40 Urb. Law. 451
    , 459-94 (2008) (surveying state statutes codifying
    the vested rights doctrine). That permit must be final and not subject to direct
    15 Section 1 of the Initiative enacts retroactive standards for the grant of the BPL lease, but we do
    not address that issue because there is a separate appeal before us from the order vacating the grant
    of the lease. Black et al. v. Bureau of Parks and Lands et al., No. BCD-21-257.
    32
    or further appeal. Powell v. Calvert County, 
    795 A.2d 96
    , 101 (Md. 2002) (“[A]
    special exception approval, whose validity is being litigated, is not finally valid
    until all litigation concerning the special exception is final. Persons proceeding
    under it prior to finality are not ‘vesting’ rights; they are commencing at ‘their
    own risk’ so that they will be required to undo what they have done if they
    ultimately fail in the litigation process.”) We have applied the test announced
    in Sahl only to resolve a vested rights challenge to retroactive changes in local
    zoning ordinances affecting a project of limited scale; we have never applied it
    to changes in state law affecting large-scale infrastructure projects overseen by
    a matrix of local, state, and federal authorities. Still, Sahl’s underlying rationale
    for protecting a developer’s good-faith expenditures in reliance on government
    approval of proposed investments against retroactive changes is not limited to
    zoning law and informs our analysis of whether NECEC has a vested right to
    proceed with Project construction under the terms of CPCN.
    [¶47] Thus, in the context of large-scale infrastructure development, we
    conclude that a claim of unconstitutional impairment of vested rights arises
    under the following conditions. First, the claimant holds a validly issued and
    final permit, license, or other grant of authority from a governmental entity that
    is not subject to any further judicial review. Second, the law under which the
    33
    permit, license, or other grant of authority was issued changed thereafter and
    would, if applied retroactively, eliminate or substantially limit the right to
    proceed with the activity authorized by the permit.                            Third, the claimant
    undertook substantial good-faith expenditures on the activity within the scope
    of the affected permit prior to the enactment of the retroactive legislation,
    meaning that the expenditure was made (1) in reliance on the affected permit
    or grant of authority, (2) before the law changed, and (3) according to a
    schedule that was not created or expedited for the purpose of generating a
    vested rights claim.16
    [¶48] Here, the PUC determined that there was a public need for the
    Project and issued the CPCN on May 3, 2019. We affirmed the issuance of the
    CPCN on March 17, 2020, holding that the PUC followed the proper procedure
    and made the public-need determination based on sufficient record evidence.

    2020 ME 34
    , ¶ 43, 
    227 A.3d 1117
    .
    16 The State parties argue that so long as there is a rational basis for the Initiative, the vested
    rights claim fails. We disagree. If the effect of the retroactive legislation is to abrogate vested rights,
    the rationale and basis for the legislation become irrelevant. See Muskin v. State Dep’t of Assessments
    & Tax’n, 
    30 A.3d 962
    , 969 (Md. 2011) (Under the Maryland Constitution, “[i]f a
    retrospectively-applied statute is found to abrogate vested rights or takes property without just
    compensation, it is irrelevant whether the reason for enacting the statute, its goals, or its regulatory
    scheme is ‘rational.’”).
    34
    [¶49] The facts before us were generated in connection with NECEC’s
    request for preliminary injunctive relief; they have not been finally adjudicated.
    Nonetheless, the record indicates at least preliminarily that NECEC began
    construction on January 18, 2021, after having secured the CPCN and all other
    necessary, Project-wide approvals from various state and federal authorities.
    The CPCN was the only approval that was affirmed after appellate review and
    not subject to any further appeals. There is substantial evidence that NECEC
    proceeded with construction thereafter in good-faith reliance on those
    approvals and intended to develop the Project to completion.             NECEC’s
    construction efforts were consistent with the baseline schedule that was first
    set in the transmission service agreements governing Project construction and
    that was later amended to reflect permitting delays. As of November 2, 2021,
    the day Maine voters approved the initiated bill, NECEC had cut around 124
    miles of the Project corridor and erected multiple transmission structures,
    spending nearly $450 million or forty-three percent of the total project cost
    estimate at that time.    NECEC spent that significant sum with the PUC’s
    assurance in issuing the CPCN that the Project served the public need.
    [¶50]   Our decision affirming the PUC’s public-need determination
    enshrined it in a final judgment—in effect providing NECEC added assurance
    35
    not only that the CPCN complied with then-existing law but also that NECEC
    could proceed with Project construction according to its terms. To be sure,
    those terms anticipated additional oversight by other government entities; in
    its order granting the CPCN, the PUC stated that it “expects that the scenic and
    recreational impacts of the [Project] will be reviewed and, to the extent
    appropriate and feasible, mitigated through the processes at the Maine
    Department of Environmental Protection (DEP) and the Land Use Planning
    Commission (LUPC).” Central Maine Power Co., Request for Approval of CPCN
    for the New England Clean Energy Connect, No. 2017-00232, Order (Me. P.U.C.
    May 3, 2019); see 35-A M.R.S. § 3132(6), (7) (acknowledging the DEP’s
    authority to modify the location, size, character, and design of transmission line
    projects that the PUC has already determined serve an identified public need).
    Obtaining the CPCN alone was necessary but not sufficient to confer the right
    to complete construction. However, we hold that NECEC could reasonably rely
    on the CPCN, and our judgment affirming the CPCN, as valid authorization to
    begin construction such that its right to proceed according to the CPCN’s terms
    could vest upon evidence that it undertook significant, visible construction in
    good faith, according to a schedule that was not created or expedited for the
    purpose of generating a vested rights claim.
    36
    [¶51]    To be clear, we do not decide whether NECEC performed
    substantial construction in good faith17 according to a schedule that was not
    created or expedited for the purpose of generating a vested rights claim.
    Although it appears from the limited record developed in connection with the
    request for preliminary injunctive relief that NECEC did so, it is up to the trial
    court to make those factual determinations on remand.
    III. CONCLUSION
    [¶52] We conclude that section 6 of the Initiative, as applied retroactively
    to the CPCN, would infringe on NECEC’s constitutionally-protected vested
    rights if NECEC can demonstrate by a preponderance of the evidence that it
    engaged in substantial construction of the Project in good-faith reliance on the
    authority granted by the CPCN before Maine voters approved the initiated bill
    17  The State appellees argue that because NECEC was aware of widespread opposition to the
    Project and knew that the Secretary of State had issued a petition allowing the Initiative’s proponents
    to collect signatures in October 2020, it could not have proceeded with construction on January 18,
    2021, in good faith. We do not accept the argument’s implicit premise that, to be acting in good faith,
    a developer must wait to commence construction pursuant to a valid permit if there is a possibility
    that a retroactive change in the law could affect the right to complete a project. As of January 2021,
    all that existed was a petition in circulation. There was no indication whether sufficient signatures
    had been gathered for the ballot measure to be presented to the Secretary of State, whether the
    Secretary of State would certify that the petition had garnered enough valid signatures to be
    presented to the Legislature, or whether the Legislature (or Maine voters acting in its stead) would
    approve the then-hypothetical initiative. In contrast, in Kittery Retail Ventures, LLC v. Town of Kittery,
    the developer submitted its revised plan to the Planning Board after a citizen amendment to the
    zoning ordinance was passed and enacted but before its effective date.

    856 A.2d 1183
    . The potential that a prospective citizens’ initiative might be voted into law after the CPCN was
    final is far too attenuated to defeat good faith.
    37
    by public referendum. Even then, NECEC’s vested right to proceed with the
    Project would not be absolute; what would be protected would be NECEC’s
    right to move forward under the terms of the validly issued CPCN as granted
    under then-existing law.
    [¶53] We emphasize that our analysis and conclusions are not based on
    the wisdom of either the Project or the Initiative. See Avangrid Networks, Inc.,
    
    2020 ME 109
    , ¶ 10, 
    237 A.3d 882
    . On this report of an interlocutory ruling
    pursuant to M.R. App. P. 24(c), the limited question that we answer is this:
    Would retroactively applying sections 4 and 5 of the Initiative, to
    the CPCN issued for the Project, as required by section 6 of the
    Initiative, violate the due process clause of the Maine Constitution,
    if NECEC undertook substantial construction consistent with and
    in good-faith reliance on the CPCN before the Initiative was
    enacted?
    Our answer is yes.
    The entry is:
    Report accepted as to one question, which is
    answered in the affirmative as indicated in the
    opinion. Remanded for further proceedings
    consistent with this opinion.
