    Before: GRIFFITH and RAO, Circuit Judges, and EDWARDS,
    Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judge RAO.
    RAO, Circuit Judge: Ali Hamza Ahmad Suliman Al Bahlul
    was Osama bin Laden’s head of propaganda at the time of the
    September 11 attacks. After he was captured in Pakistan,
    Al Bahlul was tried and convicted by a military commission in
    Guantanamo Bay. Our court subsequently vacated two of his
    three convictions on ex post facto grounds and remanded his
    case back to the military courts, where his life sentence was
    reaffirmed. In this most recent appeal, Al Bahlul raises six
    different statutory and constitutional challenges to his sentence
    and detention, including three challenges to the appointment of
    the officer who convened the military commission under the
    Military Commissions Act of 2006. Only one argument has
    merit: In reaffirming Al Bahlul’s life sentence, the Court of
    Military Commission Review failed to apply the correct
    harmless error standard, so we reverse and remand for the court
    to reassess the sentence. Each of Al Bahlul’s remaining
    arguments lacks merit for the reasons explained below.
    I.
    Al Bahlul is a Yemeni national who travelled to
    Afghanistan in the late 1990s to join Al Qaeda. Once there,
    Al Bahlul pledged an oath of loyalty to Osama bin Laden,
    underwent military training, and eventually led Al Qaeda’s
    propaganda efforts. Most notably, he created a video for
    bin Laden in the aftermath of the U.S.S. Cole bombing that
    celebrated the terrorist attack on an American destroyer and
    called for jihad against the United States. Al Bahlul also served
    as bin Laden’s personal assistant and secretary for public
    relations. Just before the attacks of September 11, 2001,
    3
    Al Bahlul arranged loyalty oaths for two of the hijackers. In the
    immediate aftermath, he operated the radio used by bin Laden
    to follow media coverage of the attacks.
    Weeks after the September 11 attacks, Al Bahlul fled to
    Pakistan, where he was captured in December 2001 and turned
    over to the United States. He was transferred in 2002 to the
    United States Naval Station at Guantanamo Bay, Cuba, where
    he has since been detained. This is Al Bahlul’s second direct
    appeal challenging his prosecution under the military
    commission system established by Congress in the Military
    Commissions Act of 2006 (“2006 MCA”), Pub. L. No. 109-
    366, 120 Stat. 2600.1 In previous opinions, we have provided a
    detailed account of his legal actions, so we provide only a brief
    summary here. See Al Bahlul v. United States (Al Bahlul I),
    
    767 F.3d 1
    , 5–8 (D.C. Cir. 2014) (en banc); Al Bahlul v. United
    States (Al Bahlul III), 
    840 F.3d 757
    , 758 (D.C. Cir. 2016) (per
    curiam).
    Al Bahlul was tried by a military commission convened
    pursuant to the 2006 MCA. Section 948h of the 2006 MCA
    provides that “[m]ilitary commissions … 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. In a number of provisions, the 2006 MCA refers
    1
    Congress amended the 2006 MCA three years later. See National
    Defense Authorization Act for Fiscal Year 2010, Pub. L. No. 111-
    84, §§ 1801–07, 123 Stat. 2190, 2574–2614 (2009) (“Military
    Commissions Act of 2009”). Al Bahlul’s trial was conducted under
    the original 2006 MCA. While the statute was for the most part “left
    … substantively unaltered as relevant” to Al Bahlul’s prosecution,
    Al Bahlul v. United States (Al Bahlul I), 
    767 F.3d 1
    , 6 n.1 (D.C. Cir.
    2014), we note explicitly throughout this opinion when citing
    provisions of the 2006 MCA that were later changed.
    4
    to the person designated under Section 948h as “the convening
    authority.” See, e.g., 10 U.S.C. §§ 950b, 950f(c). The 2006
    MCA also vests the Convening Authority with significant
    powers and responsibilities other than convening military
    commissions. Both the government and Al Bahlul agree that
    the Convening Authority has the responsibilities of a
    constitutional “Officer[ ] of the United States” under the
    Appointments Clause, U.S. CONST. art. II, § 2, cl. 2, but they
    disagree about whether the Convening Authority is properly
    considered a principal or inferior officer. The Convening
    Authority’s final decision to “approve, disapprove, commute,
    or suspend [a] sentence” is reviewed by the Court of Military
    Commission Review (“CMCR”), although the 2006 MCA
    provides for review “only with respect to matters of law.” 10
    U.S.C. §§ 950b(c)(2)(C), 950f(d) (2006).
    In 2007, the Secretary of Defense designated Susan
    Crawford as the Convening Authority. Prior to her designation,
    Crawford was already serving as a Senior Judge of the Court
    of Appeals for the Armed Forces (“CAAF”)2 as well as an
    employee serving a three-year term in the Senior Executive
    Service. Crawford convened a commission to try Al Bahlul of
    three substantive offenses enumerated in the 2006 MCA:
    conspiracy to commit war crimes, providing material support
    for terrorism, and soliciting others to commit war crimes. See
    id. §§ 950u, 950v(b)(25),
    950v(b)(28) (2006). The three
    charges were predicated on largely the same conduct.
    Al Bahlul refused to participate in the proceedings and
    instructed his appointed defense counsel to waive objections
    and to abstain from any motions. Al Bahlul, however, admitted
    every factual allegation against him but one—an allegation that
    2
    CAAF reviews the military’s intermediate courts. It is the military’s
    highest appellate court.
    5
    he once used a suicide belt. Nonetheless, he pleaded not guilty
    on the grounds that American tribunals lack the authority to try
    him.
    The commission convicted Al Bahlul on all three counts
    and sentenced him to life in prison. Crawford approved the
    conviction, and the CMCR affirmed. See United States v.
    Al Bahlul, 
    820 F. Supp. 2d 1141
    (CMCR 2011). A panel of this
    court then vacated all three convictions on the grounds that the
    2006 MCA did not authorize prosecutions based on conduct
    occurring before 2006 unless the conduct was already
    prohibited as a war crime and triable by military commission.
    See Al Bahlul v. United States, No. 11-1324, 
    2013 WL 297726
    (D.C. Cir. Jan. 25, 2013).
    Sitting en banc, this court upheld Al Bahlul’s conviction
    for conspiracy while vacating the two remaining convictions.
    See Al Bahlul I, 
    767 F.3d 1
    . Because Al Bahlul raised no
    objections at trial, we reviewed his newly raised constitutional
    objections only for plain error. See
    id. at 8–11.
    We held that
    Al Bahlul’s ex post facto challenge to his conspiracy
    conviction failed under the plain error standard on two
    grounds: First, “the conduct for which he was convicted was
    already criminalized under 18 U.S.C. § 2332(b),” which
    punishes conspiracies to kill United States nationals; second,
    “it is not ‘plain’ that conspiracy was not already triable by law-
    of-war military commission.”
    Id. at 18.
    After vacating the
    remaining two convictions under the Ex Post Facto Clause,3
    id. 3
      We “assume[d] without deciding that the Ex Post Facto Clause
    applies at Guantanamo” based on the government’s concession. Al
    Bahlul 
    I, 767 F.3d at 18
    . In so doing, we emphasized that we were
    “not to be understood as remotely intimating in any degree an
    opinion on the question” of the Clause’s extraterritorial application.
    6
    at 27–31, the court ordered the case to be remanded, “after
    panel consideration, … to the CMCR to determine the effect,
    if any, of the two vacaturs on sentencing.”
    Id. at 31.4
    On remand to the CMCR, Al Bahlul argued for the first
    time that Crawford’s appointment as Convening Authority was
    unlawful, both on statutory and constitutional grounds. He also
    argued that intervening Supreme Court precedent required de
    novo review of his ex post facto challenge to the conspiracy
    conviction. Without remanding to the military commission, the
    CMCR rejected these arguments on the merits and determined
    that a life sentence continued to be appropriate, reasoning that
    the military commission would have imposed the same
    sentence even if Al Bahlul had been convicted only of
    conspiracy. See Al Bahlul v. United States, 
    374 F. Supp. 3d 1250
    (CMCR 2019). Al Bahlul appealed to this court, and we
    have exclusive jurisdiction under 10 U.S.C. § 950g.
    Al Bahlul raises six discrete arguments on appeal. First, he
    argues that the CMCR applied the wrong harmless error
    standard in reviewing his sentence on remand by failing to
    determine beyond a reasonable doubt that the military
    commission would have imposed the same sentence absent the
    two convictions vacated by Al Bahlul I. Second, he claims that
    Id. (quoting Petite v.
    United States, 
    361 U.S. 529
    , 531 (1960) (per
    curiam)).
    4
    After Al Bahlul I, a panel of this court again vacated the conspiracy
    conviction, this time concluding Al Bahlul had raised meritorious
    structural separation of powers objections that could not be forfeited
    below. See Al Bahlul v. United States (Al Bahlul II), 
    792 F.3d 1
    (D.C.
    Cir. 2015). The court once again took Al Bahlul’s case en banc,
    reinstated the conspiracy conviction, and remanded the case to the
    CMCR. See Al Bahlul III, 
    840 F.3d 757
    .
    7
    Crawford’s appointment as the Convening Authority violated
    the 2006 MCA, which in his view permits the Secretary to
    designate only individuals who are already officers of the
    United States at the time of the designation. Third, he argues
    that Crawford’s appointment violated the Appointments
    Clause of the Constitution because the Convening Authority
    acts as a principal officer who must be appointed by the
    President with Senate approval. Fourth, even if the Convening
    Authority is an inferior officer, Al Bahlul contends that
    Crawford’s appointment violated the Appointments Clause
    because Congress did not vest the appointment of the
    Convening Authority in the Secretary by law. Fifth, Al Bahlul
    argues that recent Supreme Court precedent requires us to
    reexamine his ex post facto challenge to his conspiracy
    conviction, this time de novo. Sixth and finally, he raises
    several challenges to the conditions of his ongoing
    confinement—namely, that he has allegedly been subjected to
    indefinite solitary confinement and denied eligibility for
    parole.
    For the reasons discussed below, only Al Bahlul’s first
    argument has merit. In reevaluating Al Bahlul’s sentence, the
    CMCR should have asked whether it was beyond a reasonable
    doubt that the military commission would have imposed the
    same sentence for conspiracy alone. We reject Al Bahlul’s
    remaining arguments. Crawford’s appointment as the
    Convening Authority was lawful, there is no reason to unsettle
    Al Bahlul I’s ex post facto ruling, and we lack jurisdiction in an
    appeal from the CMCR to entertain challenges to the
    conditions of Al Bahlul’s ongoing confinement. We therefore
    affirm in part, reverse in part, and dismiss Al Bahlul’s petition
    in part for lack of jurisdiction. We remand for reconsideration
    of the sentence under the correct standard.
    8
    II.
    We start with Al Bahlul’s sole meritorious claim.
    Al Bahlul argues that the CMCR erred by reassessing his
    sentence without remand to the military commission and,
    further, by misapplying the harmless error doctrine in
    maintaining his life sentence. In Al Bahlul I, the en banc court
    directed the CMCR to “determine the effect, if any, of the two”
    vacated convictions on Al Bahlul’s 
    sentence. 767 F.3d at 31
    .
    While we conclude that the CMCR had the discretion to
    reassess the sentence without remanding to the military
    commission, we agree that the CMCR erred by reaffirming
    Al Bahlul’s life sentence without first determining that the
    constitutional errors were harmless beyond a reasonable doubt.
    As an initial matter, the CMCR correctly determined that
    it had the authority to assess Al Bahlul’s sentence without
    remand. In the analogous court-martial context governed by the
    Uniform Code of Military Justice (“UCMJ”), intermediate
    military appellate courts may in some circumstances revise
    sentences without remand to the court-marital. See Jackson v.
    Taylor, 
    353 U.S. 569
    , 579–80 (1957). In United States v.
    Winckelmann, CAAF held that intermediate military courts
    should consider four factors in determining whether to reassess
    a sentence without remand: (1) whether the defendant was tried
    by military judges; (2) whether there are “dramatic changes” in
    the penalty the defendant is exposed to; (3) whether “the nature
    of the remaining offenses capture the gravamen of criminal
    conduct included within the original offenses”; and (4) whether
    “the remaining offenses are of the type that judges of the courts
    of criminal appeals should have the experience and familiarity
    with to reliably determine what sentence would have been
    imposed at trial.” 
    73 M.J. 11
    , 15–16 (CAAF 2013).
    9
    In light of the parallels in text and structure, we have
    previously relied on the UCMJ to inform our interpretation of
    the statutes governing military commissions. See In re Al
    Nashiri, 
    835 F.3d 110
    , 122–23 (D.C. Cir. 2016). Here, we
    conclude that the CMCR did not err when it applied the
    Winckelmann factors in concluding it was appropriate to
    evaluate the sentence without remanding to a military
    commission. In the court-martial context, a military court has
    discretion under Winckelmann to reevaluate a sentence without
    remand, and we have held that the military should not be held
    to higher procedural standards in the context of military
    commissions than it would in the court-martial context.
    Id. To the contrary,
    if a “procedure for courts-martial is considered
    adequate to protect defendants’ rights, the same should be true
    of the review procedure for military commissions.”
    Id. at 123.
    Whether to remand for reconsideration of a sentence is left
    to the military court’s discretion, so we review the CMCR’s
    decision only for abuse of discretion. See 
    Winckelmann, 73 M.J. at 12
    . The CMCR properly applied the Winckelmann
    factors, and it was not an abuse of discretion to reevaluate
    Al Bahlul’s sentence without remand to the military
    commission. After we vacated two of his convictions, Al
    Bahlul remained subject to the same maximum sentence—life
    in prison—and the one remaining conviction for conspiracy
    was predicated on the same conduct as the two that were
    vacated. Moreover, as the CMCR noted, “conspiracy to
    commit murder is not so novel a crime that” the intermediate
    court would be “unable to ‘reliably determine what sentence
    would have been imposed at trial’” with respect to Al Bahlul’s
    similar crime of conspiracy to commit war crimes, including
    the murder of noncombatants. Al 
    Bahlul, 374 F. Supp. 3d at 1273
    (quoting 
    Winckelmann, 73 M.J. at 16
    ).
    10
    In reevaluating Al Bahlul’s sentence, however, the CMCR
    applied the wrong legal standard. When an intermediate
    military court “reassesses a sentence because of a prejudicial
    error, its task differs from that which it performs in the ordinary
    review of a case.” United States v. Sales, 
    22 M.J. 305
    , 307
    (CMA 1986). To “purge[ ]” the sentence “of prejudicial error,”
    the new sentence should be less than or equal to the sentence
    that would have been delivered by the trier of fact “absent any
    error.”
    Id. at 308.
    Here, the CMCR concluded that the original
    life sentence remained appropriate because any constitutional
    error in Al Bahlul’s original sentence was harmless. Yet the
    CMCR misapplied well-established harmless error principles.
    In ordinary criminal proceedings, an error may be found
    harmless if the court determines it had no “substantial and
    injurious effect or influence in determining the jury’s verdict.”
    United States v. Whitmore, 
    359 F.3d 609
    , 622 (D.C. Cir. 2004)
    (quoting Kotteakos v. United States, 
    328 U.S. 750
    , 776 (1946)).
    Yet “before a federal constitutional error can be held harmless,
    the court must be able to declare a belief that it was harmless
    beyond a reasonable doubt.” Chapman v. California, 
    386 U.S. 18
    , 24 (1967) (emphasis added). The military courts have
    adopted the same standard in the court-martial context for
    reviewing whether a constitutional error was harmless, see
    
    Sales, 22 M.J. at 307
    –08 (concluding that in cases of
    constitutional error “the Court of Military Review should be
    persuaded beyond a reasonable doubt that its reassessment has
    rendered harmless any error affecting the sentence adjudged at
    trial”), and the government concedes that the same standard
    should apply in the military commission context, Gov’t Br. 28.
    We agree. In both the court-martial context and in civilian
    criminal proceedings, a constitutional error is considered
    harmless only if found to be harmless beyond a reasonable
    doubt. As all parties agree, military commissions should be
    11
    subject to the same harmless error standard that is uniformly
    applied in other criminal contexts in cases involving
    constitutional errors.
    The CMCR purported to rely on the standard articulated
    by the Court of Military Appeals in Sales but erred in the
    application of the standard. The CMCR maintained that it could
    reaffirm the original sentence because the court was “confident
    that, absent the error, the [military commission] would have
    sentenced the appellant to confinement for life.”
    Id. at 1273.
    Yet nowhere did the court explicitly address whether the errors
    were harmless beyond a reasonable doubt. Because the errors
    identified by Al Bahlul I were constitutional ex post facto
    violations, the CMCR applied the wrong harmless error
    standard and therefore abused its discretion. See Cooter & Gell
    v. Hartmarx Corp., 
    496 U.S. 384
    , 405 (1990) (holding that it is
    necessarily an abuse of discretion to apply the wrong legal
    standard). We therefore reverse and remand for the CMCR to
    redetermine “the effect, if any, of the two vacaturs on
    sentencing.” Al Bahlul 
    I, 767 F.3d at 31
    . Under the harmless
    error standard the government concedes applies, the CMCR
    must determine the constitutional errors were harmless beyond
    a reasonable doubt.
    III.
    Next, Al Bahlul argues that Crawford’s appointment by
    the Secretary as Convening Authority was unlawful on three
    grounds. First, he maintains that the 2006 MCA permits the
    Secretary to select only individuals who are already serving as
    officers of the United States. Alternatively, he argues that the
    Convening Authority acts as a principal officer, thus requiring
    presidential appointment after Senate confirmation. Finally,
    Al Bahlul argues that even if the Convening Authority is an
    12
    inferior officer, Crawford’s appointment by the Secretary
    violated the Appointments Clause, because the 2006 MCA did
    not vest the Secretary with the power to appoint an inferior
    officer.
    Al Bahlul’s challenges require us to interpret both the
    Constitution’s Appointments Clause and the 2006 MCA. The
    Appointments Clause provides that the President
    shall nominate, and by and with the Advice and
    Consent of the Senate, shall appoint
    Ambassadors, other public Ministers and
    Consuls, Judges of the supreme Court, and all
    other Officers of the United States, whose
    Appointments are not herein otherwise
    provided for, and which shall be established by
    Law; but the Congress may by Law vest the
    Appointment of such inferior Officers, as they
    think proper, in the President alone, in the
    Courts of Law, or in the Heads of Departments.
    U.S. CONST. art. II, § 2, cl. 2. Courts have long referred to
    officers who must be appointed by the President with Senate
    confirmation as “principal officers.” See, e.g., United States v.
    Germaine, 
    99 U.S. 508
    , 509–11 (1878). The statute
    establishing the Convening Authority, Section 948h of the
    2006 MCA, provides that “[m]ilitary commissions … 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 Convening Authority has
    significant authority, including wide discretion to review a
    military commission’s findings and sentences. See 10 U.S.C.
    § 950b(c)(2)(C) (2006) (“[T]he convening authority may, in
    13
    his sole discretion, approve, disapprove, commute, or suspend
    the sentence in whole or in part.”).
    Crawford’s appointment was entirely consistent with both
    the Constitution and the 2006 MCA: Section 948h allows the
    Secretary to select any official of the United States to serve as
    the Convening Authority, including mere employees.
    Moreover, the Convening Authority is an inferior officer.
    Because the 2006 MCA vests the Secretary with the power to
    appoint inferior officers by law, Crawford’s appointment was
    constitutional.
    A.
    Al Bahlul argues that Crawford’s appointment as
    Convening Authority violated the 2006 MCA because the
    Secretary may designate only an “officer or official of the
    United States.” 10 U.S.C. § 948h. According to Al Bahlul, the
    term “officer” refers only to military officers, while the term
    “official” refers to civilian officers. Either way, he contends the
    Convening Authority must be a person who is already a
    principal or inferior officer appointed through the procedures
    prescribed by the Appointments Clause. Al Bahlul argues that
    Crawford’s appointment was therefore unlawful because she
    was only an employee at the time of her designation. In the
    government’s view, the 2006 MCA’s reference to “officer”
    includes all officers of the United States in the constitutional
    sense, both military and civilian, while the term “official”
    refers broadly to other government employees. The MCA thus
    allows the Secretary to select an employee to serve as
    Convening Authority. The government has the better reading
    of the statute. The term “official” includes government
    employees who are not “Officers of the United States” in the
    constitutional sense. Even assuming Crawford was only an
    14
    employee at the time of her appointment, a question we do not
    decide,5 her designation was consistent with the requirements
    of the 2006 MCA.
    The 2006 MCA permits the Secretary to designate either
    officers or officials of the United States as the Convening
    Authority. Against the Appointments Clause background and
    in light of the text and structure of the MCA, “official” cannot
    be read to mean “civilian officer.” In the constitutional context,
    an “officer” is someone who “occup[ies] a continuing position
    established by law” and who “exercis[es] significant authority
    pursuant to the laws of the United States.” Lucia v. SEC, 
    138 S. Ct. 2044
    , 2051 (2018) (quotation marks omitted). An
    “official,” on the other hand, can be an employee with less
    responsibility. See 
    Lucia, 138 S. Ct. at 2050
    (referring to “mere
    employees” as “officials with lesser responsibilities who fall
    outside the Appointments Clause’s ambit”). Congress regularly
    uses the word “official,” a term that extends beyond officers in
    5
    The parties dispute the significance of the fact that Crawford was
    already serving as a senior judge of CAAF. The government
    contends that her status as a senior judge made her a principal officer,
    which would cure several of the problems alleged by Al Bahlul. See
    Gov’t Br. 47–50. Judges of CAAF are appointed by the President
    with Senate confirmation; however, “[a] senior judge shall be
    considered to be an officer or employee of the United States … only
    during periods the senior judge is performing duties [as senior
    judge.]” 10 U.S.C. § 942(e)(4). Because we conclude that
    Crawford’s appointment was lawful on both statutory and
    constitutional grounds regardless of whether she was already a
    principal or inferior officer of the United States, we need not address
    the significance of her status as a senior judge of CAAF.
    15
    the constitutional sense, to refer broadly to government
    employees.6
    By contrast, and consistent with the constitutional
    background, Congress generally uses the word “officer” to
    refer to principal and inferior officers who must be appointed
    in accordance with the Appointments Clause. See Steele v.
    United States, 
    267 U.S. 505
    , 507 (1925) (explaining that it is
    usually “true that the words ‘officer of the United States,’ when
    employed in … statutes … have the limited constitutional
    meaning”). The 2006 MCA is no exception. The statute refers
    throughout to military officers by using explicit language like
    “commissioned officer of the armed forces.” See, e.g., 10
    6
    For example, in a provision of the Military Commissions Act of
    2009 governing access to classified information, the government
    must submit a declaration signed by any “knowledgeable United
    States official possessing authority to classify information.” 10
    U.S.C. § 949p-4(a)(1). The statute does not limit the term “official”
    to officers of the United States, and employees can possess the
    authority to classify information. Similarly, in a statute governing
    “military custody for foreign Al-Qaeda terrorists,” Congress
    provided that certain procedures do “not apply when intelligence,
    law enforcement, or other Government officials of the United States
    are granted access to an individual who remains in the custody of a
    third country”—again suggesting that the term “official” applies
    broadly to those who work for the United States government.
    National Defense Authorization Act for Fiscal Year 2012, Pub. L.
    No. 112-81, § 1022, 125 Stat. 1298, 1564 (2011). This consistent
    usage extends to other parts of the United States Code as well. For
    instance, in a provision punishing the bribery of public officials, the
    term “public official” includes “an officer or employee or person
    acting for or on behalf of the United States, or any department,
    agency or branch of Government … in any official function.” 18
    U.S.C. § 201(a)(1).
    16
    U.S.C. § 948i(a) (2006) (“Any commissioned officer of the
    armed forces on active duty is eligible to serve on a military
    commission.”);
    id. § 948j(b) (“A
    military judge shall be a
    commissioned officer of the armed forces.”);
    id. § 949b(b) (prohibiting
    the consideration of military commission
    performance when “determining whether a commissioned
    officer of the armed forces is qualified to be advanced in
    grade”). Rather than use the military officer language found
    elsewhere in the 2006 MCA, Section 948h uses the more
    generic “officer … of the United States,” without qualification.
    This language mirrors the text of the Constitution’s
    Appointments Clause, U.S. CONST. art. II, § 2, cl. 2, which is a
    strong indication that “officer … of the United States” refers to
    all officers in the constitutional sense, not just military officers.
    See 
    Steele, 267 U.S. at 507
    ; United States v. Mouat, 
    124 U.S. 303
    , 307 (1888).
    Contrary to this plain meaning, Al Bahlul maintains that
    “officer or official of the United States” includes only officers
    in the constitutional sense. Yet this interpretation reads the
    word “official” out of the statute. See Hibbs v. Winn, 
    542 U.S. 88
    , 101 (2004) (“A statute should be construed so that effect is
    given to all its provisions, so that no part will be inoperative or
    superfluous, void or insignificant.”). Al Bahlul attempts to
    sidestep the surplusage problem by limiting “officer” to
    military officers and “official” to civilian officers. Yet nothing
    in the 2006 MCA suggests that Congress used “official” in an
    unorthodox sense meaning constitutional “officer.” Similarly,
    there is no indication that “officer” means exclusively military
    officers in Section 948h. To the contrary, the statute explicitly
    refers to military officers in other provisions as “commissioned
    officer[s] of the armed forces.” 10 U.S.C. §§ 948i(a), 948j(b),
    949b(b) (2006). We decline to limit Section 948h’s use of the
    general term “officer” only to military officers, a conclusion
    17
    inconsistent with other provisions of the 2006 MCA as well as
    the ordinary constitutional meaning of “officer … of the United
    States.”
    Al Bahlul next cites 10 U.S.C. § 101(b)(1), which states
    that “‘officer’ means a commissioned or warrant officer” in
    Title 10 of the United States Code. This particular definition of
    “officer,” however, appears in Section 101(b)’s list of
    definitions specifically “relating to military personnel,” not in
    Section 101(a)’s general list of definitions, which apply to Title
    10 without qualification. In other words, the specialized
    definition found in Section 101(b)(1) would apply only if we
    first assumed what Al Bahlul is trying to prove—that “officer”
    in Section 948h refers only to military personnel. Nothing in
    the text of Section 948h suggests that it refers specifically to
    military personnel, so the military personnel definition in
    Section 101(b)(1) is of little use. Moreover, Section 101(b)(1)
    was not enacted as part of the 2006 MCA; it was enacted over
    four decades earlier as part of a general definitional statute. See
    Pub. L. No. 87-649, 76 Stat. 451, 452 (1962). General
    definitional statutes are more easily defeasible by context than
    definitions found in the same statute as the language at issue.
    See Antonin Scalia & Bryan Garner, Reading Law: The
    Interpretation of Legal Texts 279–80 (2012) (“[A] legislature
    has no power to dictate the language that later statutes must
    employ. … [W]hen the definition set forth in an earlier statute
    provides a meaning that the word would not otherwise bear, it
    should be ineffective.”).
    Here, the text is unambiguous: The Secretary may
    designate either an officer or an official of the United States,
    and the term official includes individuals who were mere
    employees prior to their designation. Thus, irrespective of
    18
    whether Crawford was already an officer, her appointment as
    the Convening Authority did not violate the 2006 MCA.
    B.
    In addition to his statutory challenge to Crawford’s
    appointment, Al Bahlul raises two constitutional challenges
    under the Appointments Clause. We start with his argument
    that Crawford’s appointment by the Secretary was
    unconstitutional because the Convening Authority acts as a
    principal officer and therefore must be appointed by the
    President with Senate confirmation. Because other executive
    officers directed and supervised the Convening Authority’s
    work, we hold that Crawford was an inferior officer and was
    therefore properly appointed by the Secretary.
    Both the government and Al Bahlul agree that Crawford
    acted as an officer of the United States for purposes of the
    Appointments Clause. The parties dispute only whether she
    acted as a principal or inferior officer. The Supreme Court
    addressed the distinction between principal and inferior
    officers most directly in Edmond v. United States, 
    520 U.S. 651
    (1997). The Court explained that “the term ‘inferior officer’
    connotes a relationship with some higher ranking officer or
    officers below the President: Whether one is an ‘inferior
    officer’ depends on whether he has a superior.”
    Id. at 662.
    More
    specifically, “‘inferior officers’ are officers whose work is
    directed and supervised at some level by others who were
    appointed by Presidential nomination with the advice and
    consent of the Senate.”
    Id. at 663;
    see also NLRB v. SW Gen.,
    Inc., 
    137 S. Ct. 929
    , 947 (2017) (Thomas, J., concurring) (“[A]
    principal officer is one who has no superior other than the
    President.”). Whether an officer is principal or inferior is a
    “highly contextual” inquiry requiring a close examination of
    19
    the specific statutory framework in question. In re Al-Nashiri,
    
    791 F.3d 71
    , 84 (D.C. Cir. 2015).
    In order to determine whether an officer is inferior because
    he is supervised by a principal officer, our court looks to three
    factors drawn from Edmond: whether there is a sufficient
    “degree of oversight,” whether the officer has “final decision-
    making authority,” and the extent of the officer’s
    “removability.” In re Grand Jury Investigation, 
    916 F.3d 1047
    ,
    1052 (D.C. Cir. 2019). Each of the three factors identified by
    Edmond and our subsequent cases indicates that the Convening
    Authority is an inferior officer. The Convening Authority’s
    decisions are not final and are subject to review by the CMCR;
    the Secretary maintains additional oversight by promulgating
    rules and procedures; and the Convening Authority is
    removable at will by the Secretary.
    First, the bulk of the Convening Authority’s decisions are
    not final. Instead, they are subject to review by the CMCR. See
    10 U.S.C. § 950f (2006). To be sure, the CMCR’s review was
    limited to questions of law under the 2006 MCA
    , id. § 950f(d), but
    the same was true in Edmond, which held that the judges of
    the Coast Guard Court of Criminal Appeals were inferior
    officers even though CAAF can review their factual findings
    only to determine whether the evidence underlying a
    conviction is sufficient as a matter of law. 
    See 520 U.S. at 665
    (noting that CAAF “will not reevaluate the facts” unless there
    is no “competent evidence in the record to establish each
    element of the offense beyond a reasonable doubt”); United
    States v. Leak, 
    61 M.J. 234
    , 239 (C.A.A.F. 2005) (“[T]his
    Court’s review is limited to questions of law.”). Despite that
    limitation, Edmond concluded that the degree of oversight was
    sufficient to render judges of the Court of Criminal Appeals
    inferior officers for Appointments Clause purposes.
    Id. at 665– 20 66
    (explaining that the narrow scope of the review did not
    “render the judges of the Court of Criminal Appeals principal
    officers. What is significant is that the judges of the Court of
    Criminal Appeals have no power to render a final decision on
    behalf of the United States unless permitted to do so by other
    Executive officers.”).
    Similarly, in Intercollegiate Broadcasting System, Inc, v.
    Copyright Royalty Board, we determined that Copyright
    Royalty Judges were inferior officers, even though direct
    review of the Judges’ factual findings was also severely
    limited. 
    684 F.3d 1332
    , 1339 (D.C. Cir. 2012) (“[T]he
    Register’s power to control the [Judges’] resolution of pure
    issues of law plainly leaves vast discretion over the rates and
    terms.”). Nonetheless, after our court severed the Judges’
    removal protections, we determined that they were inferior
    officers.
    Id. 1341–42
    (“Although individual … decisions will
    still not be directly reversible, the Librarian would be free to
    provide substantive input on non-factual issues. … This,
    coupled with the threat of removal satisfies us that the
    [Copyright Royalty Judges’] decisions will be constrained to a
    significant degree by a principal officer (the Librarian).”). The
    power to review even pure legal determinations is “is a non-
    trivial limit on” an officer’s decisionmaking such that an
    officer may be deemed an “inferior” officer for purposes of the
    Appointments Clause.
    Id. at 1339.
    Al Bahlul emphasizes that the CMCR is unable to review
    several of the Convening Authority’s consequential powers.
    Most importantly, the Convening Authority has the power to
    modify charges, overturn a verdict, or commute a sentence, all
    of which are effectively unreviewable. See 10 U.S.C.
    § 950b(c)(2)(C) (2006) (“[T]he convening authority may, in
    his sole discretion, approve, disapprove, commute, or suspend
    21
    the sentence in whole or in part.”). Once again, Edmond is
    closely analogous: The judges of the Court of Criminal
    Appeals have the power to “independently weigh the evidence”
    without “defer[ence] to the trial court’s factual findings.” 
    See 520 U.S. at 662
    (quotation marks omitted). If they decide to
    reverse the factual findings underlying a conviction, thus
    overturning the verdict, CAAF has no power to reverse that
    decision unless the evidence was insufficient as a matter of law.
    See
    id. at 665;
    Leak, 61 M.J. at 239
    . Although the Convening
    Authority may make some final decisions, that authority is
    consistent, as in Edmond, with being an inferior officer. See
    
    Edmond, 520 U.S. at 662
    (emphasizing that the significance of
    the authority exercised by an officer does not necessarily
    determine whether he is principal or inferior, because all
    constitutional officers “exercis[e] significant authority on
    behalf of the United States”).
    Second, the Secretary maintains a degree of oversight and
    control over the Convening Authority’s work through policies
    and regulations. The Secretary has the power to prescribe
    procedures and rules of evidence governing military
    commissions, including rules governing “post-trial
    procedures.” 10 U.S.C. § 949a(a). The Secretary has exercised
    that authority to regulate and to oversee the conduct of the
    Convening Authority in detailed ways. See, e.g., R.M.C.
    104(a)(1) (2007) (prohibiting the Convening Authority from
    censuring, reprimanding, or admonishing the military
    commission, its members, or the military judge); R.M.C. 407
    (2007) (prescribing rules for the forwarding and disposition of
    charges); R.M.C. 601(f) (2007) (“The Secretary of Defense
    may cause charges, whether or not referred, to be transmitted
    to him for further consideration, including, if appropriate,
    referral.”); see also In re Grand 
    Jury, 916 F.3d at 1052
    (concluding that special counsel Robert Mueller was an inferior
    22
    officer because the Attorney General “has authority to rescind
    at any time the Office of Special Counsel regulations”). While
    the Secretary’s power to define rules of evidence and other
    procedures does not by itself make the Convening Authority an
    inferior officer, it provides further evidence that the Convening
    Authority’s work is directed by the Secretary and subject to his
    supervision.
    Finally, the Convening Authority is removable at will by
    the Secretary. The 2006 MCA includes no explicit tenure
    provisions, and “[t]he long-standing rule relating to the
    removal power is that, in the face of congressional silence, the
    power of removal is incident to the power of appointment.”
    Kalaris v. Donovan, 
    697 F.2d 376
    , 401 (D.C. Cir. 1983); see
    also Oral Argument at 14:25 (Al Bahlul’s counsel conceding
    that “there’s no tenure protection” for the Convening
    Authority). As the Supreme Court concluded in Edmond, the
    “power to remove officers … is a powerful tool for control.”
    
    Edmond, 520 U.S. at 664
    .
    Al Bahlul argues that the power to remove means little
    here because the Convening Authority’s “‘judicial acts’ are
    statutorily insulated from” the Secretary’s interference. Reply
    Br. 16. The 2006 MCA provides that “[n]o person may attempt
    to coerce or, by any unauthorized means, influence … the
    action of any convening, approving, or reviewing authority
    with respect to his judicial acts.” See 10 U.S.C. § 949b(a)(2)(B)
    (2006). Yet such insulation was also present in Edmond: The
    judges of the Court of Criminal Appeals are removable at will
    only by the Judge Advocate General, who is prohibited from
    “influenc[ing] (by threat of removal or otherwise) the outcome
    of individual 
    proceedings.” 520 U.S. at 664
    (citing UCMJ Art.
    37, 10 U.S.C. § 837). In other words, the judicial acts of the
    Court of Criminal Appeals, like the judicial acts of the
    23
    Convening Authority, have some statutory insulation from
    interference by the person holding the removal power. The
    removal power was nonetheless an important factor in Edmond
    in determining that the Court of Criminal Appeals judges are
    inferior officers. Similarly, we held in Intercollegiate that
    removal at will is a powerful tool for control even when direct
    review is limited. 
    See 684 F.3d at 1340
    –41 (severing removal
    restrictions was sufficient to make Copyright Royalty Judges
    inferior officers); see also In re Grand 
    Jury, 916 F.3d at 1052
    –
    53 (holding that special counsel Robert Mueller was an inferior
    officer in part because he “effectively serve[d] at the pleasure
    of an Executive Branch officer” and because the “control
    thereby maintained” ensured a meaningful degree of
    oversight).
    Edmond requires that inferior officers have “some level”
    of direction and supervision by a principal 
    officer, 520 U.S. at 663
    , not necessarily total control. Even inferior officers
    exercise discretion and important duties established by law.
    The Appointments Clause allows the appointment of such
    officers to be vested in a Head of Department so long as the
    proper chain of command is maintained. See 1 Annals of Cong.
    499 (1789) (statement of James Madison) (explaining that the
    President may rely primarily on subordinates because “the
    lowest officers, the middle grade, and the highest, will depend,
    as they ought, on the President,” establishing a “chain of
    dependence”). Here, the factors identified by the Supreme
    Court in Edmond establish that the Convening Authority is an
    inferior officer. As an inferior officer, Crawford’s appointment
    by the Secretary was perfectly consistent with the
    Appointments Clause.
    24
    C.
    Even if the Convening Authority is an inferior officer,
    Al Bahlul argues that Crawford’s appointment violated the
    Appointments Clause because Section 948h does not vest the
    Secretary with the power to appoint an inferior officer.
    Al Bahlul Br. 28–34. According to Al Bahlul, Section 948h
    does no more than describe a duty that can be delegated to
    existing constitutional officers. He also argues that the 2006
    MCA does not create “a freestanding office” to which an
    inferior officer could be appointed.
    Id. Contrary to Al
    Bahlul’s
    characterizations, the 2006 MCA’s conferral of the power to
    designate the Convening Authority was sufficient to vest the
    Secretary with the constitutional power to appoint an inferior
    officer.
    Article II of the Constitution grants Congress broad power
    to “vest the Appointment of … inferior Officers” in “the Heads
    of Departments.” U.S. CONST., art. II, § 2, cl. 2. Whether to
    exercise this power is explicitly left to Congress’s discretion,
    to be done “as they think proper.”
    Id. This power is
    reinforced
    by Article I, which authorizes Congress “[t]o make all Laws
    which shall be necessary and proper for carrying into
    Execution … Powers vested by this Constitution in the
    Government of the United States, or in any Department or
    Officer thereof.”
    Id., art. I, §
    8, cl. 18. Thus, “Congress has
    plenary control over the … existence of executive offices.”
    Free Enterprise Fund v. PCAOB, 
    561 U.S. 477
    , 500 (2010);
    see also Myers v. United States, 
    272 U.S. 52
    , 129 (1926) (“To
    Congress under its legislative power is given the establishment
    of offices, the determination of their functions and jurisdiction,
    the prescribing of reasonable and relevant qualifications and
    rules of eligibility of appointees, and the fixing of the term for
    which they are to be appointed and their compensation.”).
    25
    Consistent with the Constitution’s requirement that
    Congress vest the power to appoint an officer “by law,” statutes
    “repeatedly and consistently distinguish[ ] between an office
    that would require a separate appointment and a position or
    duty to which one [can] be ‘assigned’ or ‘detailed’ by a
    superior.” Weiss v. United States, 
    510 U.S. 163
    , 172 (1994).
    While the explicit use of the term “appoint” may “suggest[ ]”
    whether a statute vests the appointment power, 
    Edmond, 520 U.S. at 658
    , our court has held that Congress need not use
    explicit language to vest an appointment in someone other than
    the President. See In re Grand 
    Jury, 916 F.3d at 1053
    –54; In re
    Sealed Case, 
    829 F.2d 50
    , 55 (D.C. Cir. 1987). Thus, reading
    the statute as a whole, we consider whether Congress in fact
    authorized a department head to appoint an inferior officer. Cf.
    In re Sealed 
    Case, 829 F.2d at 55
    (reading the statute as a whole
    and determining it “accommodat[ed] the delegation” of
    responsibilities by the Attorney General to a special counsel).
    Two features of the 2006 MCA suggest that Congress
    exercised its broad power to vest the appointment of the
    Convening Authority in the Secretary. First, after establishing
    and defining the office of the Convening Authority in
    considerable detail, Section 948h specifically provides that the
    Secretary will choose the person to fill that office. Second,
    because the text and structure of the statute are readily
    interpreted as a lawful exercise of Congress’s power to vest the
    appointment power in a department head, we decline to adopt
    an interpretation that would render the provision
    unconstitutional.
    The text and structure of the 2006 MCA show that
    Congress established a new office—the Convening
    Authority—and tasked the Secretary with selecting the person
    to fill that office. By referring to the Convening Authority by
    name and using the definite article “the,” several sections of the
    26
    2006 MCA strongly suggest that the Convening Authority is a
    distinct office and not simply a duty to be performed by
    existing officers. See, e.g., 10 U.S.C. § 948i(b) (2006) (“[T]he
    convening authority shall detail as members of the commission
    such members … [who] in the opinion of the convening
    authority, are best qualified for the duty.”); see also
    id. § 950b(a); id.
    § 950b(b); § 948l(a). The text of the 2006 MCA
    is in stark contrast to the UCMJ, which specifically lists
    existing officers who are permitted to perform the function of
    convening courts-martial. See 10 U.S.C. § 822. The 2006
    MCA, on the other hand, grants the Secretary the power to
    designate any officer or official to be “the convening
    authority,” a new office created by the statute. Section 948h
    authorizes the Secretary to designate the person who will
    occupy that office. Because no magic words are required to
    grant a department head the power to appoint an inferior
    officer, this designation is sufficient for the power to be vested
    “by law.”
    Al Bahlul’s reading not only runs contrary to the ordinary
    meaning of the statute, but would unnecessarily raise serious
    constitutional concerns. We decline to read the 2006 MCA in a
    manner that would render Crawford’s appointment
    unconstitutional when another interpretation is readily
    available. See United States v. X-Citement Video, Inc., 
    513 U.S. 64
    , 69 (1994) (“[A] statute is to be construed where fairly
    possible so as to avoid substantial constitutional questions.”).
    As discussed above, the 2006 MCA unambiguously permits the
    Secretary to designate as the Convening Authority an
    individual who, at the time of the designation, was a mere
    employee. Both parties agree, however, that the Convening
    Authority exercises the type of significant responsibilities that
    properly belong to an officer of the United States. Thus, if
    Section 948h does not vest in the Secretary the power to
    27
    appoint an inferior officer, then the statute permits an employee
    to exercise the duties of an officer of the United States without
    a constitutional appointment. Nothing in the text or structure of
    the statute requires us to interpret it in this way, which flies in
    the face of the plain meaning and would raise significant
    constitutional doubts. Al Bahlul’s final challenge to
    Crawford’s appointment therefore fails.
    Reading the statute as a whole, we conclude that in Section
    948h Congress exercised its broad power under the
    Appointments and Necessary and Proper Clauses to create an
    office of the Convening Authority and to vest the power to
    appoint this inferior officer in the Secretary. Thus, Crawford’s
    appointment satisfied the requirements of the Constitution as
    well as the 2006 MCA.
    IV.
    Next, Al Bahlul asks the court to reconsider his ex post
    facto challenge to his conspiracy conviction, a challenge we
    reviewed for plain error in Al Bahlul I because it was forfeited
    below. 
    See 767 F.3d at 18
    –27. The law-of-the-case doctrine
    dictates that “the same issue presented a second time in the
    same case in the same court should lead to the same result.”
    LaShawn A. v. Barry, 
    87 F.3d 1389
    , 1393 (D.C. Cir. 1996) (en
    banc) (emphasis omitted). The doctrine bars re-litigation “in
    the absence of extraordinary circumstances.” Christianson v.
    Colt Indus. Operating Corp., 
    486 U.S. 800
    , 817 (1988). We
    may reconsider a prior ruling in the same litigation if there has
    been “an intervening change in the law.” Kimberlin v. Quinlan,
    
    199 F.3d 496
    , 500 (D.C. Cir. 1999). None of these limited
    circumstances are present here and therefore we cannot
    reconsider our forfeiture ruling in Al Bahlul I.
    28
    According to Al Bahlul, the Supreme Court’s decision in
    Class v. United States fundamentally changed the law of
    forfeiture and plain error review. See 
    138 S. Ct. 798
    (2018).
    But 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.
    Id. at 803–05.
    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.”
    Id. at 803;
    see also
    id. at 805
    (concluding
    that a “guilty plea does not bar a direct appeal in these
    circumstances”) (emphasis added). The Court twice
    emphasized that Class had not waived his objections through
    conduct other than his guilty plea, see
    id. at 802, 807,
    thus
    making clear that the Court was addressing only the effect of
    pleading guilty. Al Bahlul did not plead guilty, so Class is
    irrelevant to this case.
    Moreover, because Class addressed only waiver, it did not
    diminish our holding in Al Bahlul I, which involved forfeiture.
    
    See 767 F.3d at 10
    . “Forfeiture is the failure to make the timely
    assertion of a right; waiver is the intentional relinquishment or
    abandonment of a known right.” United States v. Miller, 
    890 F.3d 317
    , 326 (D.C. Cir. 2018) (quotation marks and alterations
    omitted). After Class, two of our sister circuits have held that
    constitutional claims should be reviewed only for plain error if
    a criminal defendant forfeits his claims before the district court.
    See United States v. Rios-Rivera, 
    913 F.3d 38
    , 42 (1st Cir.
    2019); United States v. Bacon, 
    884 F.3d 605
    , 610–11 (6th Cir.
    2018). Those decisions are consistent with the “familiar”
    principle “that a constitutional right may be forfeited in
    criminal as well as civil cases by the failure to make timely
    assertion of the right.” Peretz v. United States, 
    501 U.S. 923
    ,
    936–37 (1991). Al Bahlul “flatly refused to participate in the
    29
    military commission proceedings and instructed his trial
    counsel not to present a substantive defense.” Al Bahlul 
    I, 767 F.3d at 10
    . This forfeiture made it appropriate for our court to
    review his ex post facto defense for plain error.
    Taking a slightly different approach, Al Bahlul argues that
    even if a challenge to the constitutionality of the statute of
    conviction would be subject to forfeiture in the Article III
    context, it cannot be forfeited in the military context, where any
    fundamental defect in the document charging the accused with
    a crime deprives the military court of jurisdiction. Al Bahlul
    Br. 37–39 (citing United States v. Ryan, 
    5 M.J. 97
    , 101 (CMA
    1978)). Even assuming arguendo that Al Bahlul has accurately
    characterized jurisdictional rules in the military context, he
    fails to identify an intervening change in the law that would
    support overturning Al Bahlul I: An ex post facto violation has
    been a constitutional defect since the Constitution’s
    ratification, and every source Al Bahlul cites for the
    proposition that military courts view jurisdiction differently
    predates Al Bahlul I. See
    id. Finally, Al Bahlul
    argues that we should reconsider the en
    banc decision because the Department of Defense has
    purportedly changed its position on a material legal question.
    In Al Bahlul I, our court held that it was “not obvious” for the
    purposes of plain error review “that conspiracy was not
    traditionally triable by law-of-war military 
    commission.” 767 F.3d at 27
    . Al Bahlul contends that the Department of Defense
    has since taken a position that is inconsistent with this court’s
    conclusion, albeit in non-binding materials such as the Law of
    War Manual. Al Bahlul Br. 40–42; see also Department of
    Defense, Law of War Manual § 1.1.1 (2015) (“This manual is
    not intended to, and does not, create any right … enforceable
    at law or in equity against the United States.”). Al Bahlul offers
    30
    no support for the notion that a party’s change of position—in
    this case, one gleaned from non-binding internal documents—
    is one of the extraordinary circumstances warranting
    reconsideration of a court’s holding under the law-of-the-case
    doctrine.7
    Furthermore, we rejected this ex post facto challenge in
    Al Bahlul I “for two independent and alternative 
    reasons.” 767 F.3d at 18
    . Al Bahlul contends that the government changed its
    position on whether conspiracy was previously triable by
    military commissions under the law of war, but his argument
    does not undermine this court’s alternative holding that “the
    conduct for which he was convicted was already criminalized
    under 18 U.S.C. § 2332(b),”
    id., which punishes conspiracies
    to kill United States nationals.
    Because Al Bahlul has failed to identify an intervening
    change of law or any other extraordinary circumstance, we
    decline to revisit the en banc court’s treatment of his ex post
    facto challenge to his conspiracy conviction.
    V.
    Finally, Al Bahlul argues that the manner in which the
    government is executing his sentence is unlawful. Specifically,
    he claims that the government has unlawfully subjected him to
    7
    In any event, the Department of Defense maintains that it has not
    changed its position on whether conspiracy was historically triable
    by military commission, which is supported by the Law of War
    Manual. See Law of War Manual § 18.23.5 (stating that “[t]he United
    States has taken the position that conspiracy to violate the law of war
    is punishable” and that “[t]he United States has” historically “used
    military tribunals to punish unprivileged belligerents for the offense
    of conspiracy to violate the law of war”).
    31
    indefinite solitary confinement and that the government’s
    current policies wrongfully bar him from parole consideration.
    Al Bahlul’s challenges to the ongoing status of his confinement
    are outside our jurisdiction on direct appeal, which is limited to
    “determin[ing] the validity of a final judgment rendered by a
    military commission.” 10 U.S.C. § 950g(a). We “may act …
    only with respect to the findings and sentence as approved by
    the convening authority and as affirmed or as set aside as
    incorrect in law by the [CMCR].”
    Id. § 950g(d). Because
    we
    have jurisdiction in this posture only to review the validity of
    the sentence, and because we may act only with respect to
    actions taken by the Convening Authority and the CMCR,
    Al Bahlul must bring any challenges to the conditions of his
    confinement through a different mechanism—likely a petition
    for a writ of habeas corpus. See Aamer v. Obama, 
    742 F.3d 1023
    , 1038 (D.C. Cir. 2014).8
    In response, Al Bahlul emphasizes that CAAF has
    interpreted its analogous jurisdictional provision to permit
    consideration on direct review of whether the “approved
    sentence is being executed in a manner that offends the Eighth
    Amendment.” United States v. White, 
    54 M.J. 469
    , 472 (CAAF
    2001). We recognize that “military courts are capable of, and
    indeed may have superior expertise in, considering challenges
    to their jurisdiction over disciplinary proceedings.” New v.
    Cohen, 
    129 F.3d 639
    , 645 (D.C. Cir. 1997). Yet we always
    have an independent obligation to determine whether our
    court’s jurisdiction is proper. Arbaugh v. Y&H Corp., 
    546 U.S. 500
    , 506–07 (2006). While we sometimes rely on parallels
    between the UCMJ and the 2006 MCA, an Article III court
    cannot assume jurisdiction by analogy to an Article II court’s
    8
    Because this court lacks jurisdiction, we express no opinion on the
    procedural or substantive merits of such a challenge.
    32
    interpretation of a different statute. The MCA permits us to act
    “only with respect to the findings and sentence as approved by
    the convening authority,” 10 U.S.C. § 950g(d), and therefore
    we lack jurisdiction to hear Al Bahlul’s challenges to the
    conditions of his ongoing confinement.
    ***
    For foregoing reasons, we affirm in part, reverse in part,
    and dismiss Al Bahlul’s petition in part for lack of jurisdiction.
    We remand for the CMCR to reevaluate Al Bahlul’s life
    sentence under the correct harmless error standards, but we
    reject Al Bahlul’s remaining challenges.
    So ordered.
