    Opinion for the Court filed by Circuit Judge HENDERSON.
    Concurring opinion filed by Senior Circuit Judge
    RANDOLPH.
    Dissenting opinion filed by Circuit Judge WILKINS.
    KAREN LECRAFT HENDERSON, Circuit Judge: Omar
    Ahmed Khadr is a former Guantanamo Bay detainee. He asks
    us to vacate his convictions for war crimes—including
    providing material support to terrorism and murder of a United
    States soldier in violation of the law of war—based on the
    alleged constitutional and statutory infirmities of those
    convictions. We dismiss the petition because Khadr waived his
    right to appellate review by this Court.
    I.
    The Military Commissions Act (MCA) provides that a
    military commission “may be convened by the Secretary of
    Defense or by any officer or official of the United States
    designated by the Secretary for that purpose.” 10 U.S.C.
    § 948h. The official, usually referred to as the “convening
    authority,” details the commission’s members, refers charges
    to the commission and reviews any conviction and sentence
    imposed by the commission. Id. §§ 948i, 950b; R.M.C. 601. On
    review of a final conviction and sentence, the convening
    authority may dismiss any charge, convict the accused of a
    lesser included offense or approve, disapprove, suspend or
    commute the sentence the commission imposed. Id. § 950b(c).
    The convening authority’s decision to approve, disapprove or
    modify the commission’s findings or sentence is the convening
    authority’s “action.” Id.
    3
    In every case in which the convening authority approves a
    commission decision that includes a finding of guilty, “the
    convening authority shall refer the case to the United States
    Court of Military Commission Review [CMCR],” a military
    appellate court. Id. § 950c(a); see also In re al-Nashiri, 
    791 F.3d 71
    , 74–75 (D.C. Cir. 2015). “[I]n each case that is
    referred,” the CMCR “shall . . . review the record . . . with
    respect to any matter properly raised by the accused,” 10
    U.S.C. § 950f(c), and “affirm only such findings of guilty, and
    the sentence or such part or amount of the sentence, as the
    Court finds correct in law and fact,” id. § 950f(d).
    We have exclusive jurisdiction to determine the validity of
    any final judgment rendered by a military commission and,
    where applicable, affirmed or set aside as incorrect in law by
    the CMCR. Id. § 950g(a); see also id. § 950c(b) (permitting
    accused to waive review in the CMCR).
    II.
    Khadr is a Canadian citizen and the son of Ahmad Khadr,
    a former senior member of al Qaeda. In 2002, when Khadr was
    15 years old, he joined an al Qaeda cell in Afghanistan that
    constructed and planted improvised explosive devices
    targeting U.S. forces. Khadr and his cell also clandestinely
    observed the movements of U.S. military convoys and
    conveyed the information to other al Qaeda operatives.
    On July 27, 2002 U.S. forces raided the compound where
    Khadr and other al Qaeda operatives were located. In the
    ensuing firefight, Khadr threw a hand grenade and killed an
    American soldier, Sergeant First Class Christopher Speer.
    Another American solider then engaged Khadr and shot him
    twice. Khadr was taken into U.S. military custody, given
    medical treatment and transferred to the Naval Base at
    Guantanamo Bay for detention.
    4
    In 2007, Khadr was charged under the MCA with murder
    and attempted murder in violation of the law of war,
    conspiracy, providing material support to terrorism and spying.
    In October 2010, Khadr entered into a pretrial agreement
    (PTA) with the convening authority. Khadr agreed, among
    other things, to plead guilty to all five charges and to waive his
    appeal rights. In the pertinent portion of the PTA, Khadr
    “offer[ed] and agree[d]” to
    [s]ign and execute the document found at
    Attachment B, a two (2) page document that is
    Military      Commission        Form        2330,
    Waiver/Withdrawal of Appellate Rights, within
    the specified timeframe found within
    Attachment Band R.M.C. 1110. In doing so I
    understand I will, at the time of execution of
    Attachment B, waive my rights to appeal this
    conviction, sentence, and/or detention to the
    extent permitted by law, or to collaterally attack
    my conviction, sentence, and/or detention in
    any judicial forum (found in the United States
    or otherwise) or proceeding, on any grounds,
    except that I may bring a post-conviction claim
    if any sentence is imposed in excess of the
    statutory maximum sentence or in violation of
    the sentencing limitation provisions contained
    in this agreement. I have been informed by my
    counsel orally and in writing of my post-trial
    and appellate rights.
    App. 59–60.
    In exchange, the convening authority agreed not to
    approve any sentence in excess of eight years’ confinement and
    to support Khadr’s request for a transfer to Canadian custody.
    5
    On October 30, 2010 Khadr and his counsel executed
    Form 2330. The executed form stated, in relevant part:
    I understand that . . . [i]f I waive or withdraw
    appellate review –
    a. My case will not be reviewed by the Court
    of Military Commission Review, or be
    subject to further review by the Court of
    Appeals for the District of Columbia
    Circuit, or by the Supreme Court.
    ....
    c. A waiver or withdrawal, once filed, cannot
    be revoked, and bars further appellate
    review.
    Understanding the foregoing, I waive my rights
    to appellate review. I make this decision freely
    and voluntarily.
    App. 71. Khadr’s counsel filed the executed form with the
    commission and thus made it part of the “record of trial.” See
    R.M.C. 808, 1103.
    The following day, October 31, 2010, the military
    commission sentenced Khadr to 40 years’ confinement. At the
    sentencing hearing, the military judge reviewed with Khadr the
    terms of his appeal waiver and confirmed in a colloquy that the
    waiver was both knowing and voluntary.
    In May 2011 the convening authority issued an action
    approving “only so much of the sentence as provides for eight
    years confinement.” App. 82. The approval action was served
    on Khadr’s counsel that same day. Despite his agreement to do
    6
    so in the PTA, Khadr did not refile his appeal waiver after the
    convening authority took action.
    In September 2012, based in part on the convening
    authority’s support, Khadr was transferred to Canada to serve
    the remainder of his sentence. The Queen’s Bench of Alberta
    ordered Khadr released on bail in 2015 and determined in 2019
    that his sentence had expired. Khadr v. Bowden Inst. (2015),
    
    590 A.R. 359
     (Can. Alta. Q.B.); Khadr v. Warden of Bowden
    Inst., 2015 ABQB 207 (Can. Alta. Q.B.). Khadr has been
    released without conditions.
    Although the convening authority approved the
    commission’s finding of guilty, he did not refer Khadr’s case
    to the CMCR for review pursuant to 10 U.S.C. § 950c. Instead,
    Khadr tried to initiate review himself in 2013—two years after
    the convening authority’s action—by filing a brief with the
    CMCR challenging his convictions. Khadr argued, inter alia,
    that the military commission lacked jurisdiction of the offenses
    to which he pleaded guilty. The CMCR held the appeal in
    abeyance pending our resolution of a series of related appeals.
    See Al Bahlul v. United States (Al Bahlul I), 
    767 F.3d 1
     (D.C.
    Cir. 2014) (en banc); Al Bahlul v. United States (Al Bahlul II),
    
    792 F.3d 1
     (D.C. Cir. 2015), rev’d en banc sub nom. Bahlul v.
    United States (Al Bahlul III), 
    840 F.3d 757
     (D.C. Cir. 2016); Al
    Bahlul v. United States (Al Bahlul IV), 
    967 F.3d 858
     (D.C. Cir.
    2020).
    After Al Bahlul IV was decided, the CMCR lifted the
    abeyance, denied all pending motions without prejudice and
    ordered the parties to file supplemental briefs addressing the
    court’s jurisdiction and the merits of Khadr’s appeal. On
    October 21, 2021 the CMCR dismissed the appeal for lack of
    subject-matter jurisdiction, concluding that “until a case is
    referred to our court by the convening authority under section
    7
    950c . . . we lack jurisdiction to review it on the merits.” United
    States v. Khadr, 
    568 F. Supp. 3d 1266
    , 1271 (C.M.C.R. 2021)
    (cleaned up). The court remanded the case to the convening
    authority with the following instructions:
    Khadr, if he elects, may ask the convening
    authority to refer his case to this court. The
    government, if it elects, has the right to state its
    position in response. We caution the parties that
    they should attend to this matter diligently.
    We do not presume to tell the convening
    authority what he should do. We do say that
    within forty-five (45) days of the date of this
    opinion the convening authority should resolve
    the referral matter. If it is not resolved by then,
    and Khadr can show . . . that (i) he has acted
    diligently on remand, including making a
    proper request seeking a referral, and (ii) the
    convening authority has refused his request, in
    fact or constructively, then we will entertain a
    petition for a writ of mandamus. In the event
    Khadr seeks a writ, we express no view on
    whether the mandamus requirements could or
    might be satisfied.
    Id. at 1277.
    On remand, the convening authority declined to refer
    Khadr’s case to the CMCR, concluding that Khadr’s appellate
    waiver was binding notwithstanding it was made before the
    convening authority took action.
    Khadr petitioned this Court for review of the CMCR’s
    dismissal for lack of subject-matter jurisdiction.
    8
    III.
    A.
    Khadr argues his convictions should be set aside for six
    reasons. He first argues that the military commission lacked
    jurisdiction of offenses that he committed as a juvenile.
    Second, he claims the Ex Post Facto Clause bars his
    convictions because the offenses of which he was convicted
    were not crimes triable by military commission at the time of
    his conduct in 2002. Third, he argues that, by authorizing the
    military commission to convict him of “purely domestic
    crimes” not cognizable under international law, the Congress
    exceeded its constitutional authority under Article I’s Define
    and Punish Clause and violated Article III’s Judicial Power
    Clause. Fourth, he argues the “specifications” of murder,
    attempted murder and conspiracy failed to state an offense
    under the MCA because they did not allege that Khadr engaged
    in conduct that could render his crimes “violations of the law
    of war.” Fifth, he claims that the MCA discriminates against
    aliens in violation of the equal protection component of the Due
    Process Clause. And finally, he contends his guilty plea was
    unknowing and involuntary and that it lacked a factual basis.
    The Government argues that we lack subject-matter
    jurisdiction of Khadr’s petition because Khadr did not satisfy
    the MCA’s exhaustion requirement, 10 U.S.C. § 950g(b), and
    because Khadr does not petition for review of a “final judgment
    of a military commission” as “affirmed or set aside as incorrect
    in law” by the CMCR, id. § 950g(a). We do not reach the
    Government’s jurisdictional arguments, however, because
    9
    Khadr’s petition is fatally infirm on another threshold ground:
    waiver.1
    Steel Company v. Citizens for a Better Environment
    established a rule of priority dictating the sequence in which a
    federal court must decide the different issues that a case
    presents. 
    523 U.S. 83
    , 93–102 (1998). But “Steel Co.’s rule of
    priority does not invariably require considering a jurisdictional
    question before any nonjurisdictional issue. Rather, courts may
    address certain nonjurisdictional, threshold issues before
    examining jurisdictional questions.” Kaplan v. Cent. Bank of
    the Islamic Republic of Iran, 
    896 F.3d 501
    , 513 (D.C. Cir.
    2018). A court therefore need not consider its subject-matter
    jurisdiction if it can dispose of the case on another non-merits
    ground. See Sinochem Int’l Co. v. Malaysia Int’l Shipping
    Corp., 
    549 U.S. 422
    , 431 (2007) (“[A] federal court has leeway
    ‘to choose among threshold grounds for denying audience to a
    case on the merits.’” (quoting Ruhrgas AG v. Marathon Oil
    Co., 
    526 U.S. 574
    , 585 (1999))); see also Kowalski v. Tesmer,
    
    543 U.S. 125
    , 129 (2004) (assuming Article III standing and
    dismissing case on prudential standing ground); Steel Co., 
    523 U.S. at
    100 n.3 (approving case resolving Younger abstention
    question before addressing subject-matter jurisdiction).
    1
    The dissent faults us for addressing the validity of Khadr’s
    appeal waiver without first giving the CMCR the chance to do so.
    See Dissenting Op. at 1–2, 5 n.1. The question before us, however,
    is whether Khadr waived his right to appellate review by this Court,
    not whether he waived his right to review by the CMCR. Those are
    distinct questions, especially given that the MCA imposes special
    limitations on an accused’s ability to waive CMCR review. See, e.g.,
    10 U.S.C. § 950c(b)(3) (accused must waive CMCR review within
    10 days after convening authority’s action). Even if the CMCR were
    to address the validity of Khadr’s appeal waiver, it would consider
    only whether Khadr properly waived its review, not ours.
    10
    Whether a defendant waived his appellate rights is a non-
    jurisdictional, non-merits threshold issue. United States v.
    Hunt, 
    843 F.3d 1022
    , 1026 n.1 (D.C. Cir. 2016). A dismissal
    based on an appeal waiver is a determination that the merits
    may not be reached because the defendant knowingly and
    voluntarily gave up his right to an appellate court’s
    consideration of the merits of his case. Although resolving a
    case on waiver “may . . . involve a brush with ‘factual and legal
    issues of the underlying dispute,’” Sinochem, 
    549 U.S. at 433
    (quoting Van Cauwenberghe v. Baird, 
    486 U.S. 517
    , 529
    (1988)), that brush does not transform the decision into a merits
    determination because deciding the waiver issue “does not
    entail any assumption by the court of substantive ‘law-
    declaring power,’” 
    id.
     (quoting Ruhrgas, 
    526 U.S. at
    584–85).
    We may therefore decide whether Khadr waived his right to
    appeal without first considering whether we have subject-
    matter jurisdiction. See id. at 431 (“[J]urisdiction is vital only
    if the court proposes to issue a judgment on the merits.”
    (quoting Intec USA, LLC v. Engle, 
    467 F.3d 1038
    , 1041 (7th
    Cir. 2006))).
    B.
    We generally may enforce a knowing, intelligent and
    voluntary waiver of the right to appeal. Hunt, 
    843 F.3d at
    1027
    (citing United States v. Guillen, 
    561 F.3d 527
    , 529 (D.C. Cir.
    2009)). Even an anticipatory waiver—a waiver made before
    the defendant knows what his sentence will be—is enforceable
    as long as the defendant “is aware of and understands the risks
    involved in his decision.” Guillen, 
    561 F.3d at 529
    . But we will
    not enforce an appeal waiver that “only arguably or
    ambiguously forecloses [the defendant’s] claims.” Hunt, 
    843 F.3d at 1027
    . Because a plea agreement is in essence a contract,
    we apply contract principles in interpreting a plea agreement.
    11
    
    Id.
     If the agreement unambiguously covers the accused’s
    claims, we dismiss the appeal. 
    Id.
    Here, Khadr agreed in the PTA to waive “my rights to
    appeal this conviction, sentence, and/or detention to the extent
    permitted by law, or to collaterally attack my conviction,
    sentence, and/or detention in any judicial forum (found in the
    United States or otherwise) or proceeding, on any grounds.”
    App. 60. This broad waiver, which took effect “at the time of
    execution of Attachment B [Form 2330],” excepts only “a post-
    conviction claim if any sentence is imposed in excess of the
    statutory maximum sentence or in violation of the sentencing
    limitation provisions contained in this agreement.” App. 60.
    Otherwise, the provision unambiguously waives any challenge
    Khadr may have made to his convictions or sentence. Khadr
    does not challenge the length of his sentence and all of the
    claims he raises on appeal therefore fall within the scope of his
    appeal waiver (except, of course, for any jurisdictional
    challenge—more on that below).
    Khadr gives a number of reasons that his unambiguous
    appeal waiver should not be enforced. None is availing. He first
    contends that his waiver is unenforceable because, in the
    military justice system, an accused cannot waive the right to
    appeal until after the convening authority takes action. Cf.
    United States v. Miller, 
    62 M.J. 471
    , 472 (C.A.A.F. 2006).
    Citing 10 U.S.C. § 950c(b)(3), he argues that the Congress
    expressly included this limitation in the MCA and that his
    appeal waiver is therefore unenforceable under the plain
    language of the statute.
    10 U.S.C. § 950c(b)(3) provides: “A waiver under
    paragraph (1) must be filed, if at all, within 10 days after notice
    of the action is served on the accused or on defense counsel.”
    Khadr reads this provision as precluding an accused from filing
    12
    an anticipatory waiver of this Court’s review. By its own terms,
    however, the provision applies only to an accused’s waiver of
    CMCR review. See id. § 950c(b)(1) (“Except in a case in which
    the sentence . . . extends to death, an accused may file with the
    convening authority a statement expressly waiving the right of
    the accused to appellate review by the United States Court of
    Military Commission Review under section 950f of this
    title.”). The MCA includes no similar statement respecting
    waiver of our review. Indeed, the statute is utterly silent
    regarding whether, and under what conditions, an accused may
    waive appellate review by this Court. Given such silence, we
    decline Khadr’s invitation to read a post-action limitation into
    the Act.
    Khadr next argues, citing Regulation for Trial by Military
    Commission (R.T.M.C.) 24-2(b)(6), that an accused can never
    waive our appellate review. But like 10 U.S.C. § 950c(b), the
    Regulation discusses only waiver of appellate review by the
    CMCR, not by this Court. Indeed, this is evident from the
    Regulation’s title: “Automatic Review by the United States
    Court of Military Commission Review.” Although the
    Regulation states that “[t]his subsection does not apply to
    appeals before the United States Court of Appeals for the
    District of Columbia Circuit,” 24-2(b)(1)(6), that language
    does not suggest an accused can waive review only by the
    CMCR and not by this Court. Rather, it merely clarifies that
    the procedures governing waiver of appellate review in the
    CMCR do not apply to us.
    Khadr also contends that his claims are non-waivable and,
    thus, even if his waiver is enforceable, he may nevertheless
    raise his arguments on appeal. His claims fall into three basic
    categories: those challenging the constitutionality of the MCA;
    those alleging that certain specifications fail to state an offense;
    and those challenging the constitutional validity of his plea.
    13
    Khadr argues that his claims challenging the
    constitutionality of the MCA are non-waivable under Class v.
    United States, 
    138 S. Ct. 798 (2018)
    . In Khadr’s view, Class
    held that a facial constitutional challenge to a statute of
    conviction can never be waived. But the holding of Class is not
    so expansive. Rather, Class held only that a plea of guilty on
    its own does not waive a defendant’s right to challenge the
    constitutionality of the statute of conviction. See id. at 803
    (framing the question presented as “whether a guilty plea by
    itself bars a federal criminal defendant from challenging the
    constitutionality of the statute of conviction on direct appeal.”
    (emphasis added)). As we have explained:
    Class’s holding was relatively narrow. The
    Supreme Court held that a criminal defendant
    who pleads guilty does not necessarily waive
    challenges to the constitutionality of the statute
    under which he is convicted. The Court did not,
    however, hold that such claims are not waivable
    at all: The Court addressed only whether a
    guilty plea constitutes a waiver “by itself.”
    Al Bahlul IV, 967 F.3d at 875 (citations omitted); see also
    United States v. Ríos-Rivera, 
    913 F.3d 38
    , 42 (1st Cir. 2019)
    (“In Class, the Supreme Court only decided that a guilty plea
    alone does not waive claims that the government could not
    constitutionally prosecute the defendant.” (cleaned up)); Oliver
    v. United States, 
    951 F.3d 841
    , 846 (7th Cir. 2020) (“Class held
    that a guilty plea, by itself, does not implicitly waive a
    defendant’s right to challenge the constitutionality of his statute
    of conviction.”).
    Class does not preclude a defendant from expressly
    waiving his right to challenge the statute of conviction on
    appeal. This limitation is evident from the structure of the
    14
    opinion. The Court first considered whether Class’s arguments
    fell within the scope of the express waivers in his plea
    agreement. Class, 138 S. Ct. at 802. It then asked whether
    Class’s guilty plea “implicitly” waived his claims, but only
    after concluding that those arguments had not been expressly
    waived in Class’s plea agreement. See id. at 803. Toward the
    end of the opinion, the Court again emphasized that Class’s
    agreement had not waived his constitutional claims. Id. at 805–
    07. That the Court first noted that Class’s arguments were not
    encompassed by his express waivers, and again referred to that
    fact at the conclusion of its opinion, strongly suggests that,
    although Class’s plea agreement did not waive his claims, it
    could have. See Al Bahlul IV, 967 F.3d at 875 (“The Court
    twice emphasized that Class had not waived his objections
    through conduct other than his guilty plea, thus making clear
    that the Court was addressing only the effect of pleading
    guilty.” (citation omitted)); Oliver, 951 F.3d at 846 (“[T]he
    Court’s reasoning assumed that Class’s plea agreement could
    have expressly waived such an argument but had not actually
    done so.”).
    In this case, Khadr expressly waived the right to appeal his
    convictions, sentence and detention. Nothing in Class, or other
    binding precedent of which we are aware, suggests that his
    non-jurisdictional claims, even if based on the Constitution,
    survive his express waiver.
    Nor are we convinced the rule Khadr advocates would
    benefit the accused. As we explained in Guillen, “[a]llowing a
    defendant to waive the right to appeal his sentence . . . gives
    him an additional bargaining chip to use in negotiating a plea
    agreement with the Government.” 
    561 F.3d at 530
    . If an appeal
    waiver were not enforced in the “mine run of cases,” the
    government would cease to rely on it and the waiver would lose
    15
    its value as a bargaining chip for the defendant. See United
    States v. Adams, 
    780 F.3d 1182
    , 1184 (D.C. Cir. 2015).
    We note that the waiver was an especially effective
    bargaining chip in this case. In exchange for agreeing to waive
    his appellate rights, Khadr’s sentence was remitted by the
    convening authority from 40 years’ imprisonment to only 8
    years’ imprisonment. In addition, Khadr was transferred—on
    the convening authority’s recommendation—to Canadian
    custody, where he was released on bail after serving only a
    portion of his sentence. There is thus good reason to believe
    that, had Khadr been unable to bargain with his appellate rights,
    he would remain in custody today.
    Khadr also argues that his constitutional challenges and his
    challenges regarding the sufficiency of the specifications are
    non-waivable under Rules 905 and 907 of the Rules for
    Military Commissions.2 This argument is easily dismissed as
    we considered and rejected the same argument in Al Bahlul I,
    2
    R.M.C. 905(e) provides:
    Failure by a party to raise defenses or
    objections or to make motions or requests which
    must be made before pleas are entered under section
    (b) of this rule shall constitute waiver. The military
    judge for good cause shown may grant relief from
    the waiver. Other motions, requests, defenses, or
    objections, except lack of jurisdiction or failure of a
    charge to allege an offense, must be raised before
    the commission is adjourned for that case and,
    unless otherwise provided in this Manual, failure to
    do so shall constitute waiver.
    Similarly, R.M.C. 907(b)(1), titled “Nonwaivable Grounds,”
    provides that “[a] charge or specification shall be dismissed at any
    stage of the proceedings if: (A) The military commission lacks
    jurisdiction to try the accused for the offense; or (B) The
    specification fails to state an offense.”
    16
    
    767 F.3d at
    10 n.6. There, Al Bahlul argued that his convictions
    should be set aside because they violated the Ex Post Facto
    Clause. 
    Id. at 8
    . Al Bahlul did not raise that claim before the
    military commission but on en banc review three of our
    colleagues suggested it was non-forfeitable under Rules 905
    and 907 either because the claim was jurisdictional or because
    it amounted to an argument that the indictment failed to allege
    an offense. See 
    id. at 48
     (Rogers, J., concurring in judgment in
    part and dissenting); 
    id. at 51
     (Brown, J., concurring in
    judgment in part and dissenting in part); 
    id.
     at 78–79
    (Kavanaugh, J., concurring in judgment in part and dissenting
    in part). The en banc majority disagreed. It explained that the
    claim was not jurisdictional because “the question whether th[e
    MCA] is unconstitutional does not involve ‘the courts’
    statutory or constitutional power to adjudicate the case.’” 
    Id.
     at
    10 n.6 (quoting United States v. Cotton, 
    535 U.S. 625
    , 630
    (2002)).
    The en banc court also rejected the suggestion that Al
    Bahlul’s ex post facto claim was non-forfeitable because it
    alleged that the indictment failed to state an offense. “Failure
    to state an offense,” the court explained, “is simply another way
    of saying there is a defect in the indictment—as evidenced by
    Rule 907’s cross-reference to Rule 307(c), which sets forth the
    criteria for charges and specifications.” 
    Id.
     Supreme Court
    precedent is clear that “such a claim can be forfeited.” Id.; see
    Cotton, 
    535 U.S. at 630
     (“[D]efects in an indictment do not
    deprive a court of its power to adjudicate a case.”); Lamar v.
    United States, 
    240 U.S. 60
    , 65 (1916) (“The objection that the
    indictment does not charge a crime against the United States
    goes only to the merits of the case.”); United States v.
    Delgado–Garcia, 
    374 F.3d 1337
    , 1342–43 (D.C. Cir. 2004)
    (“[T]he substantive sufficiency of the indictment is a question
    that goes to the merits of the case.”).
    17
    Our en banc Al Bahlul I decision controls. Khadr argues
    his constitutional claims are non-waivable because they are
    “jurisdictional.” But his claims are no more jurisdictional than
    was Al Bahlul’s ex post facto claim. Like Al Bahlul’s ex post
    facto claim, Khadr’s claims challenge only the constitutionality
    of the MCA, not the courts’—or commission’s—power to
    adjudicate his case.3 Challenges to the constitutionality of a
    statute are not themselves jurisdictional.4 See United States v.
    3
    Notably, although the Judicial Power Clause appears in
    Article III of the Constitution, the clause does not limit the power of
    the courts, but of the Congress. See U.S. CONST. art. III § 1. In
    particular, the clause curbs the Congress’s power to transfer
    adjudicatory authority from Article III to non-Article III tribunals.
    See CFTC v. Schor, 
    478 U.S. 833
    , 850 (1986) (The clause “bar[s]
    congressional attempts to transfer jurisdiction to non-Article III
    tribunals.” (cleaned up)). Khadr’s Judicial Power Clause argument
    therefore does not implicate our subject-matter jurisdiction.
    4
    Only one of Khadr’s arguments is conceivably jurisdictional
    in the true sense. Khadr contends that the military commission lacked
    jurisdiction to convict him because of the Juvenile Delinquency Act
    (JDA), 
    18 U.S.C. §§ 5031
     et seq. But the JDA, by its own terms,
    forbids criminal proceedings against juveniles only in a “court of the
    United States.” 
    18 U.S.C. § 5032
    . Although the JDA does not define
    “court of the United States,” definitions elsewhere in the U.S. Code
    cast serious doubt on whether a military commission qualifies as a
    court. See, e.g., 
    28 U.S.C. § 451
     (“The term ‘court of the United
    States’ includes the Supreme Court of the United States, courts of
    appeals, district courts . . . and any court created by Act of Congress
    the judges of which are entitled to hold office during good
    behavior.”). Military courts have also held that the JDA does not
    apply to military tribunals. See, e.g., United States v. Thieman, 
    33 C.M.R. 560
    , 561–62 (1963) (“Since it appears Congress enacted the
    Federal Juvenile Delinquency Act solely under its Article III powers
    and made no mention of persons in the military, we see no
    justification for extending the application of the Act to the military
    judicial system absent additional legislation.”). Likewise, Supreme
    Court precedent and notable military treatises cast doubt on Khadr’s
    
    18 Williams, 341
     U.S. 58, 66 (1951) (“Even the
    unconstitutionality of the statute under which the proceeding is
    brought does not oust a court of jurisdiction.”). Indeed, if a
    constitutional challenge to a statute of conviction were
    jurisdictional, a federal court would be required to address, sua
    sponte, the constitutional validity of every statute of conviction
    in every criminal case it considered. See United States v.
    Baucum, 
    80 F.3d 539
    , 541 (D.C. Cir. 1996). That practice
    would not only consume judicial resources but also run afoul
    of a long line of Supreme Court decisions declining to consider
    constitutional claims not raised by the parties. Id.; see also
    Mazer v. Stein, 
    347 U.S. 201
    , 206 n.5 (1954) (“We do not reach
    for constitutional questions not raised by the parties.”); Al
    Bahlul III, 
    840 F.3d at 780
     (Millett, J., concurring) (“To hold
    otherwise would mean that ‘a court would be required to raise
    [a Judicial Power Clause challenge] sua sponte each time it
    reviews a decision of a non-Article III tribunal,’ even if the
    parties do not contest that issue.” (quoting Al Bahlul II, 
    792 F.3d at 32
     (Henderson, J., dissenting))).
    Likewise, Khadr’s argument that his claims challenging
    the sufficiency of his specifications are non-waivable is
    materially identical to the argument the en banc court deemed
    argument. See Ex Parte Vallandigham, 
    68 U.S. (1 Wall.) 243
    , 253
    (1864) (although a military commission has “discretion to examine,
    to decide and sentence,” it is not “judicial . . . in the sense in which
    judicial power is granted to the courts of the United States”); Ex
    Parte Quirin, 
    317 U.S. 1
    , 39 (1942) (“[M]ilitary tribunals . . . are not
    courts in the sense of the Judiciary Article.”); Ortiz v. United States,
    
    138 S. Ct. 2165
    , 2179–80 (2018) (“[T]he commission [at issue in
    Vallandigham] lacked ‘judicial character.’ It was more an adjunct to
    a general than a real court.”); W. WINTHROP, MILITARY LAW AND
    PRECEDENTS 49 (2d Ed. 1920) (“None of the statutes governing the
    jurisdiction or procedure of the ‘courts of the United States’ have any
    application to [a court-martial].”).
    19
    forfeited in Al Bahlul I. Khadr neither points to any facts nor
    identifies an intervening change in the law that would support
    distinguishing our decision in Al Bahlul I.5 Cf. Al Bahlul IV,
    967 F.3d at 876 (declining to reconsider Al Bahlul I based on
    argument that defect in charging document deprives military
    court of jurisdiction).
    Nevertheless, Khadr’s challenge to the validity of his
    guilty plea is reviewable notwithstanding his appeal waiver.
    See Garza v. Idaho, 
    139 S. Ct. 738
    , 745 (2019) (“[C]ourts agree
    that defendants retain the right to challenge whether the waiver
    itself is valid and enforceable.”); Guillen, 
    561 F.3d at 529
     (“A
    defendant may waive his right to appeal his sentence as long as
    his decision is knowing, intelligent, and voluntary.”). “An
    appeal waiver is knowing, intelligent, and voluntary if the
    defendant ‘is aware of and understands the risks involved’ in
    waiving the right to appeal.” United States v. Lee, 
    888 F.3d 503
    , 506 (D.C. Cir. 2018) (quoting Guillen, 
    561 F.3d at 529
    ).
    Granted, “[a] written plea agreement in which the defendant
    5
    Khadr contends Al Bahlul I is inapposite because that case
    involved forfeiture whereas this case involves waiver. Granted, our
    Al Bahlul I decision relied in part on the distinction between waiver
    and forfeiture in rejecting the argument that Rules 905 and 907
    rendered Al Bahlul’s ex post facto claim non-forfeitable but the
    decision also rejected the argument for reasons unrelated to the
    distinction between waiver and forfeiture. See Al Bahlul I, 
    767 F.3d at
    10 n.6 (“Nor is Bahlul’s ex post facto argument
    ‘jurisdictional.’ . . . The question whether [the MCA] is
    unconstitutional does not involve ‘the courts’ statutory or
    constitutional power to adjudicate the case.’” (quoting Cotton, 
    535 U.S. at 630
    )); 
    id.
     (“Failure to state an offense is simply another way
    of saying there is a defect in the indictment . . . . As Cotton makes
    clear, such a claim can be forfeited.”); 
    id.
     (citing Delgado-Garcia,
    
    374 F.3d at
    1342–43, a case involving waiver, for the proposition

    an issue that goes to the merits of a case”).
    20
    waives the right to appeal” serves as “strong evidence that the
    defendant knowingly, intelligently, and voluntarily waived
    the right to appeal,” we still examine the entire record to
    determine whether the plea was knowing, intelligent and
    voluntary. Id. at 507.
    Here, the record shows that Khadr’s plea was made
    knowingly, intelligently and voluntarily. The waiver language
    of the PTA and the Form 2330 is clear, both documents are
    signed by Khadr and his counsel and the military judge
    confirmed in a colloquy at Khadr’s sentencing that he waived
    his appeal rights knowingly and voluntarily. See id. (listing
    factors).
    Khadr argues his plea is invalid because the military judge
    misinformed him about the nature and constitutionality of the
    charges against him. In essence, Khadr claims that his plea
    should be set aside because the judge ruled against him on the
    merits of his legal claims. This argument is too clever by half.
    A defendant cannot challenge a plea based on an alleged error
    of law that was raised, rejected and then waived pursuant to the
    plea. Khadr, aware that the military judge had rejected his
    theories, nonetheless chose to plead guilty and expressly waive
    his right to appeal those erroneous (in his view) rulings. He
    cannot now have the merits of his waived claims reviewed on
    appeal by arguing his waiver was invalid because those claims
    were wrongly decided. Indeed, the basic principle behind an
    appeal waiver is that the defendant gives up his right to have an
    appellate court review the merits of his arguments in exchange
    for valuable consideration. See Guillen, 
    561 F.3d at 530
    (“Allowing the defendant to waive this right . . . improves the
    defendant’s bargaining position and increases the probability
    he will reach a satisfactory plea agreement with the
    Government.”).
    21
    For the foregoing reasons, we conclude that Khadr
    unambiguously waived his right to challenge his conviction on
    appeal and did so knowingly, intelligently and voluntarily. We
    therefore dismiss the petition.
    So ordered.
    RANDOLPH, Senior Circuit Judge, concurring: I agree with
    Judge Henderson’s opinion, but I write in the hope of clarifying
    once and for all exactly what the Supreme Court held in Steel
    Co. and what it did not. Steel Co. v. Citizens for a Better
    Environment, 
    523 U.S. 83
     (1998). See Maj. Op. 9–10.
    The issue in Steel Co., as the opinion’s author – Justice
    Scalia – described it, was this: must Article III jurisdiction (e.g.,
    standing) always be confirmed before a federal court may move
    on to decide the merits of a controversy? The Court answered
    yes even though a federal court may decide a controversy before
    determining whether statutory jurisdiction exists.1
    Steel Co. thus held in the clearest possible terms that a
    “merits question cannot be given priority over an Article III
    question,” and so rejected Justice Stevens’ contrary opinion (see
    note 1 supra). 
    523 U.S. at
    97 n.2.
    A few years after Steel Co., the author of that opinion,
    Justice Scalia, again writing for the Court majority, wrote that it
    was unnecessary to decide a statutory jurisdictional question
    because it was so clear that the plaintiffs would lose on the
    merits. See Verizon Commc’ns Inc. v. L. Offs. of Curtis V.
    Trinko, LLP, 
    540 U.S. 398
    , 416 n.5 (2004). In support, Justice
    Scalia cited, in addition to his opinion in Steel Co., the Court’s
    opinion in Nat’l R. R. Passenger Corp. v. Nat’l Ass’n of R. R.
    Passengers, 
    414 U.S. 453
    , 456 (1974). The Court there held that
    “it is only if . . . a right of action exists that we need consider
    whether the respondent had standing to bring the action and
    whether the District Court had jurisdiction to entertain it.” 
    Id.
    1
    “Justice Stevens’ opinion concurring in the judgment,
    however, claims that the question whether [the statute] permits this
    cause of action is also ‘jurisdictional,’ and so has equivalent claim to
    being resolved first.” Steel Co., 
    523 U.S. at
    88–89.
    2
    Our own decisions have followed suit: we have often bypassed
    statutory jurisdiction to decide merits issues.2
    It is fair to ask what any of this has to do with this case. My
    answer is very little, which is why Judge Henderson’s opinion
    does not dwell on it. That is, we are not asked here to decide the
    merits before deciding “jurisdiction,” whether Article III
    jurisdiction, as in Steel Co. or statutory jurisdiction, as in
    National Rail.
    As to what remains of the case, I am with Judge Henderson.

    WILKINS, Circuit Judge, dissenting: There is but one
    issue directly before this Court: jurisdiction. With no final
    order to review on appeal, I believe the answer to whether we
    have jurisdiction must be no. In order to sidestep jurisdiction
    and dismiss the appeal on other grounds, the majority upholds
    Mr. Khadr’s appeal waiver. It does so, however, without the
    complete record of the proceedings below, contrary to our
    precedent, and also without the benefit of a finding of the
    validity of the appeal waiver by the United States Court of
    Military Commission Review (“CMCR”) or the trial judge in
    the first instance. Because we are not permitted to make
    findings about the scope or validity of an appeal waiver without
    the complete record, and because “we are a court of review, not
    of first view,” Capitol Servs. Mgmt., Inc. v. Vesta Corp., 
    933 F.3d 784
    , 789 (D.C. Cir. 2019) (quoting Cutter v. Wilkinson,
    
    544 U.S. 709
    , 718 n.7 (2005)), I respectfully dissent.
    I.
    As outlined by the majority, the Military Commissions
    Act (“MCA”) provides that the convening authority “shall refer
    the case to the [CMCR]” whenever it approves a military
    commission decision “includ[ing] a finding of guilty[.]”
    10 U.S.C. § 950c(a). The only listed exception to such automatic
    referral concerns waiver. And should a defendant waive the right
    to appeal, such waiver “must be filed, if at all, within 10 days
    after notice of the action is served on the accused or on defense
    counsel.” Id. § 950c(b)(3). Although the MCA grants this
    Court exclusive jurisdiction, it does so on a limited basis. As
    such, our jurisdiction is triggered when asked to review final
    judgments rendered by “the military commission as approved
    by the convening authority and, where applicable, as affirmed
    or set aside as incorrect in law by the [CMCR].” Id. § 950g(a).
    This limited record speaks for itself. In October 2010, Mr.
    Khadr entered into a pretrial agreement with the convening
    authority. Later that month, Mr. Khadr signed Military
    2
    Commission Form 2330, Waiver/Withdrawal of Appellate
    Rights (“Form 2330”). Although the military commission
    made a guilty finding, the convening authority failed to refer
    Mr. Khadr’s case under § 950c, and Mr. Khadr never filed his
    appeal waiver under § 950c(b)(3). As relevant here, the CMCR
    dismissed Mr. Khadr’s appeal on October 21, 2021, for lack of
    jurisdiction, finding it is authorized by statute only to “review
    cases that have been ‘referred to the Court by the convening
    authority.’ 10 U.S.C. § 950f(c).” United States v. Khadr, 
    568 F. Supp. 3d 1266
    , 1275 (C.M.C.R. 2021).
    For our purposes, it is important to note that the CMCR
    expressly declined to resolve any issues regarding the scope or
    validity of Mr. Khadr’s appeal waiver. Khadr, 568 F. Supp. 3d
    at 1274 n.11. Instead, the CMCR counseled Mr. Khadr to ask
    the convening authority to refer his case within 45 days, and
    should that fail, the CMCR would “entertain a petition for a
    writ of mandamus.” Id. at 1277. It also found that should the
    convening authority refer the case, “the briefing of the merits
    appeal will be deemed completed.” Id. Rather than
    immediately following these instructions, Mr. Khadr petitioned
    this Court on November 8, 2021, for review of the CMCR’s
    decision dismissing for lack of jurisdiction.
    The CMCR’s decision, dismissing Mr. Khadr’s case for
    lack of jurisdiction and remanding with instructions can hardly
    be characterized as “affirm[ing] or set[ting] aside as incorrect
    in law” a decision which is required to grant us jurisdiction
    under § 950g(a). For that reason, the government urges us to
    dismiss this appeal for lack of jurisdiction, because the CMCR
    remand order before us is not a “final order,” as we have
    squarely held. See Khadr v. United States, 
    529 F.3d 1112
    ,
    1115–16 (D.C. Cir. 2008) (dismissing appeal for lack of
    jurisdiction after holding that CMCR remand order was not a
    final order).
    3
    II.
    The majority rejects this straightforward approach.
    Instead, the majority reasons that unlike subject matter
    jurisdiction, we need not satisfy ourselves that we have
    statutory jurisdiction as a threshold matter in every instance, so
    we can dismiss the appeal on a non-merits ground, like waiver.
    Maj. Op. 8–10. While the majority’s approach is correct in
    theory, see United States v. Shemirani, 
    802 F.3d 1
    , 3 & n.1
    (D.C. Cir. 2015), it is not appropriate to decide whether Mr.
    Khadr waived his right to appeal in this instance.
    Mr. Khadr’s guilty plea was taken in open court on
    October 25, 2010. Oral Arg. Tr. 20. However, the appeal
    waiver was not executed until five days later, on October 30,
    2010. 
    Id.
     at 20–21; App. 71. The transcript of October 25 is
    in the record before us, but not the transcript from any
    proceedings on October 30. The trial judge said on October 25
    that he would review the appeal waiver with the defendant
    later, but we do not have transcripts to determine whether that
    ever occurred, and if so, what was said by the judge, counsel,
    or Mr. Khadr. Granted, the military commission made a
    cursory statement to Mr. Khadr on October 25, asking him if
    he understood that he was waiving his right to appeal. App.
    304–05. But we do not know if there were subsequent
    statements made on October 30 that could impact the
    voluntariness of the appeal waiver or the scope of the waiver.
    See, e.g., United States v. Kaufman, 
    791 F.3d 86
    , 88 (D.C. Cir.
    2015) (holding that “the district court made two problematic
    statements in explaining the waiver provision in the plea
    agreement” that “transformed the nature” of the written appeal
    waiver); United States v. Godoy, 
    706 F.3d 493
    , 495 (D.C. Cir.
    2013) (where district court mischaracterized scope of appeal
    waiver provision during colloquy with the defendant, the oral
    4
    pronouncement controlled over the terms of the appeal waiver
    in the written plea agreement).
    Furthermore, while the trial judge made a finding on
    October 25 that Mr. Khadr knowingly and involuntarily waived
    his right to trial, there is no concomitant finding that he
    knowingly and voluntarily waived his right to an appeal. App.
    311–12.     Thus, we do not even have before us a
    contemporaneous finding in the trial court that the appeal
    waiver was knowing and voluntary. Without the oral colloquy
    and the trial court’s finding, we cannot adequately review
    whether the appeal waiver was knowing and involuntary and
    whether its scope encompasses the claims being asserted by
    Mr. Khadr. As we have previously explained,
    a written plea agreement on its own does not end
    the inquiry. Rather, the court of appeals must
    examine, among other things, the clarity of the
    written plea agreement, the defendant's
    signature on the agreement, defense counsel's
    signature on the agreement, the defendant's
    statements at the plea hearing, defense counsel's
    statements at the plea hearing, and the judge's
    questioning and statements at the plea hearing.

    In sum, we should not make a determination about the
    scope and validity of the appeal waiver in the first instance, and
    even if it were appropriate to do so, our precedent does not
    permit us to do so unless we have the complete record. 1 The

    the order we have before us on review, so it is not properly before
    us. It also relies on the larger record, see
