    Before DYK, O’MALLEY, and WALLACH, Circuit Judges.
    WALLACH, Circuit Judge.
    Trong Nguyen is an employee at the Department of
    Homeland Security (“the Agency”). In Mr. Nguyen’s
    former position as a Deportation Officer, GS-12, he
    worked closely with the United States Attorney’s Office
    for the Northern District of California (“USAO”). Mr.
    Nguyen was often required to testify as a witness during
    grand jury proceedings and criminal prosecutions. In
    2008, Mr. Nguyen was subject to an Office of Professional
    Responsibility (“OPR”) investigation, in which he admit-
    ted to making false statements during a police investiga-
    tion.   Following the OPR investigation, the Agency
    initiated a removal proceeding, ultimately imposing a
    fourteen-day suspension after three of the five charges
    were sustained.
    Two years later, the USAO determined that Mr. Ngu-
    yen’s disciplinary history impaired his credibility as a
    witness, pursuant to Giglio v. United States, 
    405 U.S. 150
    (1972). The USAO notified the Agency that it would no
    longer allow Mr. Nguyen to testify in criminal prosecu-
    tions or swear out complaints. The Agency initiated
    another removal proceeding, this time charging “Inability
    to Perform Full Range of Duties.” J.A. 62–64. Upon
    finding the charge was sustained, the Agency mitigated
    the proposed penalty and demoted Mr. Nguyen to a
    Detention and Removal Assistant, GS-7. The Merit
    Systems Protection Board (“Board”) affirmed, holding the
    Agency did not impermissibly subject Mr. Nguyen to
    double punishment, and that Mr. Nguyen’s due process
    rights were not violated. This court affirms.
    NGUYEN   v. DHS                                           3
    BACKGROUND
    Mr. Nguyen is an employee at the Agency’s San Fran-
    cisco Detention and Removal Operations Field Office. 1 In
    his former position as a Deportation Officer, Mr. Nguyen
    was responsible for preparing documentation for warrants
    of arrest and deportation, cooperating with USAO prose-
    cutors in apprehending and prosecuting aliens, and
    participating in deportation and exclusion proceedings.
    On April 18, 2008, the Agency issued a notice of pro-
    posed removal charging Mr. Nguyen with (1) lack of
    candor in an investigation; (2) preparing an official letter
    for unauthorized purposes; (3) misuse of law enforcement
    resources; (4) receiving and reviewing an alien file for
    unofficial business; and (5) conduct unbecoming a federal
    law enforcement officer. The first charge was based on a
    police investigation relating to a suspicious purchase of a
    Sears refrigerator owned by Mr. Nguyen. The Agency
    alleged that Mr. Nguyen told two separate and incon-
    sistent stories about how he obtained the refrigerator.
    Mr. Nguyen told a police detective investigating the
    matter that Sears delivered the refrigerator to his house
    with someone else’s name on the receipt. He seemingly
    disclaimed any knowledge of the matter by saying he was
    immediately suspicious of the transaction. However, Mr.
    Nguyen also told a Sears manager that he paid an indi-
    vidual named “Jeff” to purchase the refrigerator with an
    employee discount, and that he paid $1,600 for a $2,000
    refrigerator. During an OPR investigation, Mr. Nguyen
    confirmed that Jeff helped him create a false transaction
    1   The record does not expressly state that Mr. Ngu-
    yen remained an Agency employee during the pendency of
    this appeal, but this court has not been informed other-
    wise. In any event, Mr. Nguyen was employed at the
    Agency during the time frame relevant to this appeal.
    4                                            NGUYEN   v. DHS
    for the refrigerator purchase, and further admitted mak-
    ing false statements during the police investigation.
    Charge two alleged that Mr. Nguyen, without author-
    ization, wrote a letter on the Agency’s letterhead to Jeff’s
    mortgage company, and signed it using his title as Immi-
    gration Information Officer. Charges three and four
    alleged that Mr. Nguyen used law enforcement resources
    to conduct queries on Jeff’s criminal history and immigra-
    tion status. Finally, charge five alleged that Mr. Nguyen
    purchased the Sears refrigerator in a business transaction
    of “questionable legality.” J.A. 70–71.
    On June 24, 2008, the Agency sustained charges three
    through five. The deciding official found the first two
    charges were not “proven to [her] satisfaction.” J.A. 74.
    Rather than removing Mr. Nguyen, the deciding official
    chose to mitigate the proposed penalty to a fourteen-day
    suspension.
    About two years later, in early 2010, the Chief Assis-
    tant U.S. Attorney (“AUSA”) and the Deputy Chief AUSA
    asked Mr. Nguyen to complete a form disclosing possible
    impeachment information. One question asked: “Have
    you been disciplined in the past?” J.A. 18. Mr. Nguyen
    answered “yes,” and provided a copy of the 2008 Notice of
    Proposed Removal, the fourteen-day suspension, and the
    OPR’s investigation report. After examining this infor-
    mation, the Chief and Deputy Chief AUSAs told Mr.
    Nguyen that the impeachment concerns it raised prevent-
    ed Mr. Nguyen from swearing out complaints or testify-
    ing.
    On June 11, 2010, Mr. Nguyen sent an email to his
    supervising deportation officer at the Agency, explaining
    that he could no longer file complaints or appear before a
    grand jury. The next month, on July 16, 2010, the Chief
    AUSA sent a letter to the Agency, confirming that Mr.
    Nguyen could no longer “testify or declare under oath in
    our criminal prosecutions.” J.A. 66 (“USAO Letter”). The
    NGUYEN     v. DHS                                        5
    USAO Letter stated that Mr. Nguyen’s responsibilities as
    a Deportation Officer required him to be “free of any
    findings or investigations” that impaired his credibility.
    J.A. 66. It stated:
    It has come to our attention that Officer Trong
    Nguyen was the subject of a 2007 investigation by
    the Department of Homeland Security, Immigra-
    tion and Customs Enforcement, Office of Profes-
    sional Responsibility in which four allegations
    against him were substantiated, including a
    charge that Officer Nguyen had displayed a “lack
    of candor in a police investigation.” That adverse
    finding unfortunately impairs Officer Nguyen’s
    credibility as a witness. Accordingly, and not-
    withstanding our considerable regard and affec-
    tion for Officer Nguyen, we must regretfully
    inform you that we cannot allow him to testify or
    declare under oath in our criminal prosecutions.
    J.A. 66.
    Following receipt of the USAO Letter, the Agency
    suspended Mr. Nguyen’s authorization to carry a firearm
    on October 7, 2010. The Agency cited the USAO Letter
    and explained: “You will be provided with work that is
    administrative in nature which does not require that you
    be armed or may lead to you having to testify or swear
    under oath.” J.A. 67.
    On November 8, 2010, the Agency issued a Notice of
    Proposed Removal for “Inability to Perform Full Range of
    Duties.” J.A. 62. The charge was based upon Giglio, 
    405 U.S. at 150
    , in which the Supreme Court required prose-
    cutors to disclose when a testifying officer may lack
    credibility. The Notice of Proposed Removal alleged that
    the USAO had found Mr. Nguyen was Giglio impaired,
    thus preventing the USAO from using him as a witness in
    any criminal proceeding. The Agency said it could not
    6                                           NGUYEN   v. DHS
    “require or order the Department of Justice to use [Mr.
    Nguyen] as a witness.” J.A. 55.
    The deciding official sustained the charge, but miti-
    gated the proposed penalty of removal to a demotion to
    Detention and Removal Assistant. He rejected Mr. Ngu-
    yen’s argument that the charge constituted impermissible
    double punishment for the same misconduct, stating he
    was neither “revisiting” the prior misconduct nor “using it
    as an aggravating factor.” J.A. 55. “The basis for this
    action is the [USAO Letter] issued by the Department of
    Justice and its impact upon [Mr. Nguyen’s] ability to
    perform the full range of duties as a law enforcement
    officer.” J.A. 55.
    The Administrative Judge (“AJ”) sustained the Agen-
    cy’s action, finding the Agency had proved that Mr. Ngu-
    yen was unable to perform the full range of his duties as a
    Deportation Officer. 2 In particular, the AJ found that the
    USAO would not permit Mr. Nguyen to testify as a wit-
    ness or make declarations under oath in federal criminal
    prosecutions, based on the USAO’s Giglio determination.
    J.A. 23–24. Not only was Mr. Nguyen barred from testify-
    ing, but he was “no longer qualified to carry and/or dis-
    charge an agency firearm.” J.A. 25. Other coworkers thus
    had to take over these duties.
    Mr. Nguyen petitioned the Board for review. The
    Board denied the petition and adopted the AJ’s initial
    decision as the Board’s final decision. Mr. Nguyen filed
    this timely appeal. This court has jurisdiction pursuant
    2   Mr. Nguyen moved for the AJ to subpoena the
    Chief AUSA for deposition, arguing he had a due process
    right to challenge the underlying Giglio determination.
    The AJ denied Mr. Nguyen’s motion, holding the Agency
    was not required to prove the merits of the USAO’s deci-
    sion.

    to 
    28 U.S.C. § 1295

    (a)(1)
    and (b)(1) (2012).
    DISCUSSION
    I.
    This court must affirm the Board unless its decision is
    “(1) arbitrary, capricious, an abuse of discretion, or other-
    wise not in accordance with law; (2) obtained without
    procedures required by law, rule, or regulation having
    been followed; or (3) unsupported by substantial evi-
    dence.” 
    5 U.S.C. § 7703
    (c); Gibson v. Dep’t of Veterans
    Affairs, 
    160 F.3d 722
    , 725 (Fed. Cir. 1998).
    The parties’ dispute in this case centers on the effect
    of the USAO’s determination that Mr. Nguyen was Giglio
    impaired and thus could not testify in criminal prosecu-
    tions. Mr. Nguyen argues the Agency was barred from
    taking adverse action in response to the USAO’s Giglio
    determination, because that determination was based on
    Mr. Nguyen’s earlier misconduct. The Agency, in turn,
    argues that it had no authority to challenge the USAO’s
    Giglio determination, which was a separate and adequate
    basis for the Agency’s adverse action.
    In Giglio, the Supreme Court held that criminal de-
    fendants have a due process right to be informed of evi-
    dence affecting a government witness’s credibility. Giglio,
    
    405 U.S. at 154
    . It required that prosecutors establish
    procedures to ensure that such exculpatory evidence is
    identified and disclosed to the defendant. 3 Id.; see also
    Brady v. Maryland, 
    373 U.S. 83
    , 87 (1963) (holding that
    3  In Giglio, the Supreme Court reversed a convic-
    tion and remanded for a new trial when the prosecutor
    did not disclose to the defendant that a government
    witness had been promised he would not be prosecuted if
    he cooperated with the government.

    8                                             NGUYEN   v. DHS
    suppression of material exculpatory evidence justifies a
    new trial “irrespective of the good faith or bad faith of the
    prosecution”). Suppression of such impeachment evidence
    requires a new trial if it could “in any reasonable likeli-
    hood” have affected the jury’s judgment. Giglio, 
    405 U.S. at 154
     (internal quotation marks and citation omitted).
    The Ninth Circuit has applied Giglio to hold that prosecu-
    tors must examine personnel files of a law enforcement
    witness they intend to call at trial for evidence affecting
    the witness’s credibility. United States v. Henthorn, 
    931 F.2d 29
    , 30–31 (9th Cir. 1991); accord Milke v. Ryan, 
    711 F.3d 998
    , 1003−07 (9th Cir. 2013).
    The USAO is responsible for ensuring compliance
    with Giglio, and is not required to rely on a law enforce-
    ment witness that it deems is Giglio impaired. See Giglio,
    
    405 U.S. at 154
     (stating that improper nondisclosure “is
    the responsibility of the prosecutor”); see also Kahn v.
    Dep’t of Justice, 
    528 F.3d 1336
    , 1340 n.4 (Fed. Cir. 2008)
    (characterizing Giglio determinations as the prosecutor’s
    responsibility). In this case, the USAO established proce-
    dures pursuant to Giglio and Henthorn requiring that
    Deportation Officers such as Mr. Nguyen must “be free of
    any findings or investigations that impair their credibil-
    ity.” J.A. 334. The USAO found Mr. Nguyen was Giglio
    impaired based on his admission during the OPR investi-
    gation that he made false statements to the police. 4
    4   The USAO Letter stated that “Officer Trong Ngu-
    yen was the subject of a 2007 investigation by the [OPR]
    in which four allegations against him were substantiated,
    including a charge that Officer Nguyen had displayed a
    ‘lack of candor in a police investigation.’” J.A. 66. Mr.
    Nguyen suggests this statement is factually incorrect,
    because the Agency did not substantiate the lack of can-
    dor charge. The AJ found, however, that the USAO Letter
    was “based on the underlying OPR Investigation,” in
    NGUYEN   v. DHS                                           9
    The Agency lacked authority to force the USAO to al-
    low Mr. Nguyen to testify or to otherwise challenge the
    USAO’s Giglio determination. See Doe v. Dep’t of Justice,
    
    95 M.S.P.R. 198
    , 205 (2003) (holding the Department of
    Homeland Security lacks authority over United States
    Attorney’s Offices); cf. City of Arlington v. Fed. Commc’ns
    Comm’n, 
    133 S. Ct. 1863
    , 1869 (2013) (“Both [agencies’]
    power to act and how they are to act is authoritatively
    prescribed by Congress.”). The Agency thus had no obli-
    gation to pass judgment on the underlying merits of the
    USAO’s finding. Rather, it was entitled to take action
    based on the undisputed effects of that finding—that Mr.
    Nguyen could no longer testify as a witness during prose-
    cutions or make declarations under oath. The Board
    found this prohibition made Mr. Nguyen unable to per-
    form the full range of his duties, and thus sustained the
    Agency’s demotion. This finding is supported by substan-
    tial evidence. The Agency’s position description for a
    Deportation Officer states that the officer, inter alia,
    “prepares documentation for Warrants of Arrest, War-
    rants of Deportation, Breaches of Bond, Demands of
    Surrender, Notices of Excludable Alien, etc.,” and
    “[t]estifies on behalf of the [A]gency before Grand Juries.”
    J.A. 317–18. The USAO’s Giglio determination prevents
    Mr. Nguyen from performing these duties.
    Mr. Nguyen argues the USAO’s Giglio determination
    “did not constitute a separate and distinct act of miscon-
    duct” and thus could not justify the Agency’s adverse
    action. Pet’r’s Br. 18. However, an adverse action need
    not be based on misconduct, but may be imposed “for such
    which Mr. Nguyen admitted knowingly making false
    statements during a police investigation, not on the later
    Agency action in 2010. J.A. 29. This finding is consistent
    with the USAO Letter’s reference to the 2007 OPR inves-
    tigation, and is supported by substantial evidence.
    10                                          NGUYEN   v. DHS
    cause as will promote the efficiency of the service.” 
    5 U.S.C. § 7513
    (a). The Board did not err in holding the
    USAO’s Giglio determination made Mr. Nguyen unable to
    perform the duties of a Deportation Officer, and that
    demoting him to another position would “promote the
    efficiency of the service.” See 
    id.
    II.
    Mr. Nguyen argues that, even if the Agency’s decision
    is otherwise supported, it impermissibly subjected him to
    double punishment for the same misconduct. The Board
    has repeatedly held “an agency cannot impose discipli-
    nary or adverse action more than once for the same mis-
    conduct.” Gartner v. Dep’t of Army, 
    104 M.S.P.R. 463
    , 466
    (2007) (citing Wigen v. U.S. Postal Serv., 
    58 M.S.P.R. 381
    ,
    383 (1993); Eichner v. U.S. Postal Serv., 
    83 M.S.P.R. 202
    ,
    ¶ 17 (1999)). Mr. Nguyen does not argue that this court
    has ever held “double punishment” is impermissible.
    Rather, he says the Board has established a rule against
    double punishment, and argues that “‘[a]n agency is
    obligated to follow precedent, and if it chooses to change,
    it must explain why.’” Pet’r’s Br. 11 (quoting M.M. & P.
    Mar. Advancement, Training, Educ. & Safety Program v.
    Dep’t of Commerce, 
    729 F.2d 748
    , 754–55 (Fed. Cir.
    1984)). Even if we were to assume Mr. Nguyen’s premise
    that we should set aside Board decisions that are incon-
    sistent with prior Board authority, the Board’s decision in
    this case is consistent with its precedent prohibiting
    double punishment.
    The Board found the 2011 demotion was based on the
    USAO’s Giglio determination, whereas the 2008 suspen-
    sion was based on Mr. Nguyen’s earlier misconduct in
    connection with the Sears refrigerator. This finding is
    supported by substantial evidence. In the 2011 action,
    the Agency charged only that the USAO had made an
    adverse Giglio determination, and would not use Mr.
    Nguyen as a government witness in any criminal prosecu-
    NGUYEN   v. DHS                                         11
    tion. For this reason, the Agency alleged Mr. Nguyen
    would be unable to “perform the full range of duties” of a
    Deportation Officer. J.A. 62. It did not mention Mr.
    Nguyen’s earlier misconduct.
    According to Mr. Nguyen, the Agency had already
    considered the possibility of Giglio impairment in the
    2008 action, so the USAO’s later adverse Giglio determi-
    nation was not a justifiable basis to distinguish the 2011
    adverse action. He argues: “In essence, the Agency chose
    to discipline [Mr. Nguyen] in 2011 after it re-examined its
    previous penalty determination for Petitioner’s miscon-
    duct in light of the U.S. Attorney office’s July 16, 2010
    letter.” Pet’r’s Br. 11. However, as discussed above, the
    USAO, not the Agency, made the Giglio determination
    forming the basis for the 2011 demotion. The Agency
    thus did not “reexamine” its earlier finding, but rather
    responded to the new development that Mr. Nguyen could
    no longer testify in criminal prosecutions.
    This situation is distinguishable from the cases Mr.
    Nguyen cites, where an agency expressly based two
    separate disciplinary actions on the same misconduct.
    For instance, the Board found double punishment imper-
    missible in Gartner, where the agency removed Ms.
    Gartner for excessive absence based in part on absences
    for which she had already been disciplined. Gartner, 104
    M.S.P.R. at 466–67. Similarly, in Westbrook v. Depart-
    ment of Air Force, 
    77 M.S.P.R. 149
    , 155 (1997), the agency
    imposed two separate suspensions—one for seven days
    and another for twenty-three days—to discipline Mr.
    Westbrook for the same act of misusing his government-
    owned vehicle.
    This case is distinguishable. “[N]o Giglio impairment
    issue was raised by the USAO” in the 2008 action, where-
    as the 2011 action was based on the USAO’s finding that
    Mr. Nguyen was Giglio impaired. J.A. 31. In sustaining
    the charges, the Agency did not impliedly rely on the
    12                                          NGUYEN   v. DHS
    underlying misconduct. Mr. Nguyen argues that “the
    very fact that the misconduct was viewed in a new way or
    was labeled as a different offense does not relieve the
    Agency of the prohibition against disciplining an employ-
    ee twice for the same misconduct.” Pet’r’s Br. 12. He
    relies on the Board’s decision in Adamek v. U.S. Postal
    Serv., 
    13 M.S.P.R. 224
    , 225–26 (1982), where the agency
    removed Mr. Adamek for “failure to meet the essential
    requirements of his position,” and charged in the notice
    two incidents of unauthorized absence for which Mr.
    Adamek had been previously disciplined. In contrast, the
    Agency in this case demoted Mr. Nguyen because he could
    no longer testify or swear out complaints, not because of
    the earlier misconduct. The second adverse action was
    not based on the same misconduct as the earlier 2008
    action, and is not inconsistent with the Board’s cases
    prohibiting double punishment.
    III.
    Finally, Mr. Nguyen argues the Agency violated his
    right to due process by denying him a meaningful oppor-
    tunity to respond to the charges brought against him. A
    federal employee contesting an adverse action has the
    right to notice and a meaningful opportunity to be heard.
    Lachance v. Erickson, 
    522 U.S. 262
    , 266 (1998) (citing
    Cleveland Bd. of Educ. v. Loudermill, 
    470 U.S. 532
    , 542
    (1985)). Mr. Nguyen argues he “had no opportunity to
    contest the determination of the U.S. Attorney’s office,”
    and that the Agency therefore “deprived him of his fun-
    damental right to due process of law by failing to provide
    him a meaningful opportunity to oppose his demotion.” 5
    5  Mr. Nguyen does not appear to contest that he
    had prior notice of the USAO’s Giglio determination. The
    AJ found that Mr. Nguyen was aware of the USAO’s
    Giglio concern well before the Agency’s Notice of Proposed
    Removal, and that it was Mr. Nguyen who first raised the
    NGUYEN   v. DHS                                           13
    Pet’r’s Br. 12. He says the Agency should have provided
    an “opportunity to confront the official to whom the Agen-
    cy ceded responsibility,” namely, the Chief AUSA who
    was responsible for the USAO letter. Reply. Br. 10–11.
    The Agency provided Mr. Nguyen with the opportuni-
    ty to contest his demotion. It notified him of the proposed
    removal and gave him thirty days to reply to the deciding
    official. Mr. Nguyen obtained counsel and responded
    orally to the deciding official, who mitigated the proposed
    removal to a demotion. 6 The Agency was not authorized
    to alter or challenge the USAO’s Giglio determination,
    and thus was not required to hear testimony by the Chief
    AUSA regarding the basis for that decision. The only
    question for the Agency was whether the USAO’s Giglio
    determination made Mr. Nguyen unable to fulfill the
    requirements of his position.
    This situation is analogous to cases where a third-
    party agency revokes a credential or qualification neces-
    sary to perform the employee’s position. In such cases,
    the Board takes the independent agency’s action at face
    value, and reviews the employing agency’s response to
    that action. For instance, in Shoffner v. Department of the
    Interior, 
    9 M.S.P.R. 265
    , 267 (1981), the agency removed
    Mr. Shoffner for failing to remain qualified for his position
    as a Hydrologic Technician due to a one-year revocation of
    his driver’s license. The Board did not consider whether
    Giglio issue with his Agency supervisors after the USAO
    inquired into his disciplinary history.
    6   The Agency also heard Mr. Nguyen’s arguments
    challenging the USAO’s Giglio determination. See J.A.
    77–87. In particular, Mr. Nguyen’s counsel argued “that
    the U.S. Attorney . . . is proceeding on false—on false
    information. I don’t think you can impeach a person for
    allegations that were brought against him that were
    found not to be substantiated.” J.A. 81.

    or not the revocation was correct, but rather reasoned
    that removal was appropriate because Mr. Shoffner “could
    no longer operate a government motor vehicle because the
    possession of a valid state motor vehicle operator’s license
    was a prerequisite to the operation of the government
    vehicle.” 
    Id.
     This made Mr. Shoffner unable to perform
    his duties as a Hydrologic Technician, “which required
    driving a vehicle alone approximately 1,000 miles per
    month.” Id.; see also Penland v. Dep’t of Interior, 
    115 M.S.P.R. 474
    , 476 (2010) (affirming the agency’s removal
    of a pilot who failed to maintain his pilot authorization). 7
    Mr. Nguyen argues that this case is not analogous to
    a licensing situation, because his position does not require
    a license. Additionally, unlike the public standards for
    obtaining a driver’s license, Mr. Nguyen argues the
    USAO’s Giglio determination “is devoid of any objective
    standard and stands essentially without sufficient articu-
    lation or explanation.” Reply Br. 15. However, Mr. Ngu-
    yen’s position as a Deportation Officer expressly requires
    testifying and swearing out complaints, and the USAO’s
    Giglio determination prevents him from performing these
    7   This case differs from situations where the agency
    itself decides to revoke a necessary credential. In those
    cases, the Board typically reviews the underlying decision
    to, e.g., revoke medical certification or procurement
    authority. See, e.g., McGillivray v. Fed. Emerg. Mgmt.
    Agency, 
    58 M.S.P.R. 398
     (1993) (agency revoked procure-
    ment authority); Siegert v. Dep’t of the Army, 
    38 M.S.P.R. 684
     (1988) (agency revoked clinical privileges); Cosby v.
    Fed. Aviation Admin., 
    30 M.S.P.R. 16
     (1986) (agency
    revoked medical certification); but see Kaplan v. Conyers,
    No. 2011-3207, 
    2013 WL 4417583
    , (Fed. Cir. Aug. 20,
    2013) (en banc) (Board lacks jurisdiction to review agen-
    cy’s finding that an employee is ineligible to occupy non-
    critical sensitive position).
    NGUYEN   v. DHS                                         15
    duties. As in third-party licensing situations, the Agency
    lacks authority to contest the USAO’s decision. The
    Board did not err in holding the Agency did not violate
    Mr. Nguyen’s due process rights.
    CONCLUSION
    For the foregoing reasons, the Board’s decision affirm-
    ing the Agency’s demotion of Mr. Nguyen is affirmed.
    AFFIRMED
