    Before: GINSBURG, TATEL, and KAVANAUGH, Circuit
    Judges.
    Opinion for the Court filed by Circuit Judge TATEL.
    TATEL, Circuit Judge: Sufyian Barhoumi, a detainee held
    at the US. naval base in Guantanamo Bay, Cuba, appeals the
    district court’s denial of his petition for a writ of habeas
    corpus. The district court found that Barhoumi was “part of”
    an al-Qaida-associated force engaged in hostilities against the
    United States or its coalition partners and was therefore
    lawfully detained under the Authorization for Use of Military
    Force. Barhoumi contends that the court erred as a matter of
    law in admitting hearsay diary evidence and in applying a
    preponderance of the evidence standard of proof. These
    arguments, however, are foreclosed by prior decisions of this
    court. Barhoumi further argues that even if the diary evidence
    was admissible, the district court erred in relying on it and in
    concluding that the evidence showed that he was “part of” an
    associated force. Finding no reversible error, we affirm.
    I.
    In response to the September 11, 2001, terrorist attacks
    on the Pentagon and World Trade Center, Congress enacted a
    joint resolution authorizing the President “to use all necessary
    and appropriate force against those nations, organizations, or
    persons he determines planned, authorized, committed, or
    aided the terrorist attacks” or “harbored such organizations or
    persons, in order to prevent any future acts of international
    terrorism against the United States by such nations,
    organizations or persons.” Authorization for Use of Military
    Force (AUMF), Pub. L. No. 107-40, § 2(a), 115 Stat. 224,
    224 (2001) (reprinted at 50 U.S.C. § 1541 note). Shortly
    thereafter, the President ordered US. military forces to invade
    Afghanistan, where the Taliban regime had been harboring al—
    Qaida.
    11
    Comm ’n v. FERC, 
    522 F.3d 378
    , 390 (DC. Cir. 2008). Thus,
    to show that the district court erred in considering the diary
    evidence, Barhoumi must “establish not that it is hearsay, but
    that it is unreliable hearsay”—a question that we address in
    Part III, below. Awad, slip 0p. at 11.
    Preponderance 0f the Evidence
    In Boumedz'ene, the Supreme Court stated that the “extent
    of the showing required of the Government in these
    [Guantanamo habeas] cases is a matter to be determined.”
    128 S. Ct. at 2271. Filling that void, the CMO provides that
    the “government bears the burden of proving by a
    preponderance of the evidence that the petitioner’s detention
    is lawful.” CMO, 
    2008 WL 4858241
     at *3. Barhoumi
    challenges the district court’s use of this standard, arguing
    that the “Government should have been required to establish
    that Barhoumi is lawfully detained under a standard of at least
    clear and convincing evidence.” Appellant’s Br. 32—33.
    This argument is also foreclosed by circuit precedent. In
    Al—Bihanz’, the detainee similarly argued for “at least” a clear
    and convincing evidence standard, while the government
    argued for a preponderance standard. Al—Bz‘hani, 590 F.3d at
    878. We concluded that “the govemment’s argument stands
    on more solid ground,” stating: “Our narrow charge is to
    determine whether a preponderance standard is
    unconstitutional. Absent more specific and relevant
    gmidance, we find no indication that it is.” Id.
    Barhoumi attempts to recast this language as mere dicta,
    but again, that argument is barred by Awad. There the panel
    interpreted Al-Biham‘ as holding that “a preponderance of the
    evidence standard is constitutional in evaluating a habeas
    petition from a detainee held at Guantanamo Bay, Cuba.”
    Awad, slip op. at 17. That resolves the question here as well.
    12
    III.
    This brings us to Barhoumi’s factual challenge. He
    argues that even if the diaries are admissible hearsay, the
    district court should have disregarded them on the ground that
    they are inherently unreliable. He further asserts that the
    government failed to establish that he was “part of’ an
    associated force and that the district court therefore erred in
    denying his habeas petition. In resolving these claims, our
    job is aided considerably by several key points of agreement
    that serve to narrow the issue before us.
    To begin with, as Barhoumi’s counsel acknowledged at
    oral argument, Barhoumi does not challenge the detention
    standard advanced by the government and adopted by the
    district court: the President has authority, pursuant to the
    AUMF, “to detain persons who were part of[,] or
    substantially supported, Taliban or al Qaida forces or
    associated forces that are engaged in hostilities against the
    United States or its coalition partners, including any person
    who has committed a belligerent act or has directly supported
    hostilities in aid of such enemy armed forces.” Hr’ g Tr. at 4.
    Nor does Barhoumi dispute that Zubaydah’s militia qualifies
    as an “associated force” that engaged in hostilities against
    US. or coalition forces. The only dispute, then, is whether
    Barhoumi was, as the district court found, “part of”
    Zubaydah’s organization.
    The parties also agree on our standard of review. “We
    review the district court’s findings of fact for clear error, its
    habeas determination de novo, and any challenged evidentiary
    rulings for abuse of discretion.” Al-Bihani, 590 F.3d at 870
    (internal citations omitted). Determining whether a detainee
    was “part of ’ an associated force is a mixed question of law
    and fact. Awad, slip op. at 17. That is, whether a detainee’s
    alleged conduct—cg, visiting an al-Qaida guesthouse or
    training at an al—Qaida camp—justifies his detention under the
    13
    AUMF is a legal question. Cf Al—Bihani, 590 F.3d at 873 n.2.
    The question whether the government has proven that
    conduct—cg, whether he in fact stayed at an al—Qaida
    guesthouse or trained at an al-Qaida campwis a factual
    question that we review for clear error.
    When reviewing for clear error, we may not reverse a
    trial court’s factual findings “even though convinced that had
    [we] been sitting as the trier of fact, [we] would have weighed
    the evidence differently.” Anderson v. Bessemer City, 
    470 U.S. 564
    , 574 (1985). Rather, we ask whether, “on the entire
    evidence,” we are “left with the definite and firm conviction
    that a mistake has been committed.” Id. at 573 (quoting
    United States v. US. Gypsum Co., 333 US. 364, 395 (1948))
    (internal quotation marks omitted). We apply this deferential
    standard, moreover, “even when the district court’s findings
    do not rest on credibility determinations, but are based instead
    on physical or documentary evidence or inferences from other
    facts.” Id. at 574. In evaluating a challenge to a district
    court’s factual findings, “we do not weigh each piece of
    evidence in isolation, but consider all of the evidence taken as
    a whole.” Awad, slip op. at 11. Equally well settled, the
    preponderance of the evidence standard “simply requires the
    trier of fact to believe that the existence of a fact is more
    probable than its nonexistence before [she] may find in favor
    of the party who has the burden.” Concrete Pipe & Prods,
    Inc. v. Constr. Laborers Pension Trust, 508 US. 602, 622
    (1993) (internal quotation marks omitted).
    Given this common ground, the ultimate and relatively
    narrow question we must answer here is this: did the district
    court commit reversible error in finding that it is more likely
    than not that Barhoumi was “part of’ Zubaydah’s associated
    force? To answer that question, we first address the evidence
    advanced by the government in support of Barhoumi’s
    detention. As we shall explain, that evidence is sufficient to
    sustain the district court’s decision, provided—and this is the
    14
    central issue in this case—that the al-Suri diary is sufficiently
    reliable. Applyn'ng the reliability requirement set forth by this
    court in Parhat v. Gates, 
    532 F.3d 834
     (DC. Cir. 2008), we
    conclude that the district court did not clearly err in relying on
    the diary.
    Evidence Supporting Barhoumi ’s Detention
    In support of his challenge to the district court’s
    determination that the evidence showed that he was “part of ’
    an associated force, Barhoumi argues that the district court
    improperly relied on a “guilt-by—association theory”
    predicated on its observation that “the travel pattern of Mr.
    Barhoumi as he describes it, is consistent with the travel
    pattern of Mr. Zubaydah and Mr. a1 Suri.” Appellant’s Br.
    37; Hr’g Tr. at 5. Membership in an “associated force,”
    Barhoumi argues, cannot be established by “evidence that the
    person’s movements and activities were similar to the
    movements of individuals who are known to be affiliated with
    al—Qaida or Taliban forces.” Reply Br. 15 (quoting
    Appellees’ Br. 30) (internal quotation marks omitted).
    Likewise, Barhoumi asserts, “mere sympathy for or
    association with an enemy organization does not render an
    individual a member” of that associated force. Appellant’s
    Br. 36 (quoting Hamlily v. Obama, 
    616 F. Supp. 2d 63
    , 75
    (D.D.C. 2009)) (internal quotation marks omitted). Rather,
    the “key inquiry” is “whether the individual functions and
    participates within or under the command structure of the
    organization—Le, whether he receives and executes orders or
    directions.” Id. (quoting Hamlily, 616 F. Supp. 2d at 75)
    (internal quotation marks omitted). According to Barhoumi,
    the record is devoid of any evidence that Barhoumi “was a
    member of Zubaydah’s purported ‘army,’ much less within
    the command structure,” or that he “received or executed any
    orders from Zubaydah, al—Suri or any other ‘member’ of
    Zubaydah’s army.” Id. at 37.
    15
    Although this court has yet to delineate the precise
    contours of the “part of” inquiry—a legal issue—we need not
    do so here because we conclude that even under the test
    espoused by Barhoumi, the district court committed no error
    in determining that it is more likely than not that he was “part
    of” Zubaydah’s militia. Cf. Awad, slip op. at 19 (noting that
    the AIHVIF contains no requirement that a detainee be “part
    of’ the “command structure” of al-Qaida). That is because in
    focusing exclusively on the travel pattern evidence, Barhoumi
    ignores other probative evidence put forth by the government
    that supports the district court’s finding that he was “part of”
    Zubaydah’s organization.
    To begin with, Barhoumi was captured along with
    Zubaydah at the Faisalabad guesthouse, a fact he
    acknowledges. Barhoumi also acknowledges that he trained
    at the Khaldan camp, though at oral argument Barhoumi’s
    counsel challenged the govemment’s claim that the Khaldan
    camp was linked to Zubaydah. The sole support for that
    connection, according to counsel, is a “Background
    Declaration” prepared by a senior intelligence analyst from
    the Defense Intelligence Agency regarding “Terrorist
    Training Camps.” This declaration, prepared on September
    19, 2008, for use in “federal court litigation,” provides an
    overview of alleged training camps in Afghanistan and states
    that “[w]hile the Khaldan camp was not an al—Qaida facility,
    Abu Zubaydah had an agreement with bin Ladin to conduct
    reciprocal recruiting efforts whereby promising trainees at the
    Khaldan camp . . . could join al-Qaida if desired.” According
    to Barhoumi’s counsel, this declaration suffers from the same
    defect as did the intelligence reports deemed unreliable in
    Parhat, namely that “there’s no information contained in that
    paragraph from which the court can assess the reliability of
    the information contained in the document.” Oral Arg. Tr. at
    9.
    16
    We shall have more to say about Parhat shortly. For
    now, however, it suffices to point out that, contrary to
    counsel’s argument, the government did put forth additional
    record evidence in support of its assertion regarding
    Zubaydah’s role at the Khaldan camp. Specifically, an FBI
    report prepared in May 2001 describes interrogation
    statements made by Ahmed Ressam, a Khaldan trainee who
    was subsequently convicted in federal district court for his
    role in the “Millennium” plot to detonate explosives at Los
    Angeles International Airport on December 31, 1999. See
    generally United States v. Ressam, 
    593 F.3d 1095
     (9th Cir.
    2010) (describing circumstances of Ressam’s conviction).
    Ressam told his interrogators that _ was “the overall
    leader of Khalden and Deronta Camps” and that there “is no
    one to whom — must report in terms of a
    superior.” He further described _ as “an associate of
    [Usama bin Laden]” who “coordinates and cooperates with
    [bin Laden] in the conduct of training and trainee movements
    between — camps and [bin Laden] camps.”
    Consistent with this report, Ressam later testified in the
    federal trial of an alleged coconspirator in the Millennium
    bomb plot that Zubaydah is “the person in charge” of the
    Khaldan camp and who “takes care of the expenses of the
    camps” under his authority. Trial Tr. at 547, United States v.
    Haouarz', No. 00-15 (S.D.N.Y. July 3, 2001). Thus, unlike
    the “bare assertions” at issue in Parhat, 532 F .3d at 847, the
    government’s assertion here that Zubaydah ran the Khaldan
    camp is backed up by testimony from a self-professed
    Khaldan trainee who, in proceedings having nothing to do
    with Barhoumi and which predated the September 11, 2001,
    attacks, attested to Zubaydah’s connection to Khaldan.
    Barhoumi’s exclusive focus on the sufficiency of the
    travel pattern evidence also overlooks what is perhaps the
    most probative record evidence that he was in fact “part of”
    Zubaydah’s associated force. On the last page of his diary,
    al-Suri lists fifteen members of Zubaydah’s militia and
    17
    describes each person’s role in the group. The relevant
    portion of this passage reads as follows:
    Sayf Al-‘Adil and Abu Muhammad Al-Masri and
    those with them are trying to take over this group,
    especially Tariq, and benefit from us and lead us to
    join Shaykh ‘Usama Bin Laden. Tariq told me that
    if anything happened to him, we should join Sayf Al—
    ‘Adil to be under his wing and that of Al-Qa’ida.
    The Group is:
    1- Tariq: Abu Zubaydah Al-Filastini: The
    commander
    2- Myself, Abu Kamil Al—Suri: Permanent
    ***
    8- ‘Ubaydah Al—Jaza’iri: Permanent
    Mat:
    12- ‘Abdullah Al Muslim . . . . Hatib and ‘Abdullah
    are undergoing training at this time on electronics by
    ‘Ubaydah Al-Jaza’iri and will leave us to go inside
    (Afghanistan) and to work with explosives and
    electronic[s] . . . for the brothers inside. The brothers
    will depend on both of them in the future for
    operations against the Americans inside of
    Afghanistan, God is willing.
    “Tariq” is the name al-Suri uses to refer to Zubaydah
    throughout the diary, and, as noted above, the district court
    found that “Ubaydah Al-Jaza’iri” refers to Barhoumi. Thus,
    contrary to Barhoumi’s assertion that the government failed to
    put forth “any” evidence that he “was a member of
    Zubaydah’s purported ‘army,’” Appellant’s Br. 37, the al—Suri
    diary—a veritable membership list—expressly states that
    Barhoumi (referred to by his alias Ubaydah al-Jaza’iri) was 21
    “Permanent” member of Zubaydah’s militia and that he was
    18
    providing explosives training to other members intending to
    fight US. forces in Afghanistan.
    Dismissing this portion of the diary as merely
    aspirational, Barhoumi’s counsel stated, “if you look at that
    diary entry, that was a hypothetical about what might happen
    in the future. It wasn’t a description of a present fact.” Oral
    Argument Tr. at 76—77. True, several portions of the excerpt
    reflect future intent—for example, al—Suri’s statement that the
    two militia members trained by Barhoumi “will leave us” to
    use explosives against Americans operating in Afghanistan.
    The rest of the passage, however, speaks to the present. It
    reports that “[t]he Group is” made up of the identified
    members, including Ubaydah al-Jaza’iri, who is described as
    a “Permanent” militia member. (Emphasis added.) And it
    states that “Hatib and ‘Abdullah are undergoing training at
    this time on electronics by ‘Ubaydah Al-Jaza’iri.” (Emphasis
    added.) Far from a mere “prediction about what might
    happen in the future,” Oral Arg. Tr. at 77, this portion of al—
    Suri’s diary describes the status of Zubaydah’s group as it
    then existed.
    Counsel further insisted that the al—Suri diary “arguably
    doesn’t mention our client” at all, and that the “Ubaydah Al—
    Jaza’iri,” referred to as a “Permanent” member of Zubaydah’s
    group, is “not necessarily our client.” Oral Arg. Tr. at 15.
    Although Barhoumi never squarely presses this argument in
    his appellate briefs, we think the issue, critical as it is, merits
    our full consideration.
    There is no doubt that Barhoumi went by the alias
    Ubaydah al-Jaza’iri, which in Arabic means Ubaydah “the
    Algerian.” Barhoumi concedes as much. In his district court
    filings, Barhoumi, who is in fact Algerian, referred to himself
    as “Sufyian Barhoumi, a/k/a Abu Obaida, Ubaydah al
    Jaza’iri, and Shafiq,” Pet’r’s Pub. Traverse to the Gov’s
    Return to the Pet. for Habeas Corpus at 2, Barhoumi v.
    19
    Obama, Misc. No. 05-1506 (D.D.C. Feb. 13, 2009), and
    Barhoumi told his interrogators that he was known as
    Ubaydah when staying at various guesthouses in Afghanistan
    and Pakistan. The only question, then, is whether the
    “Ubaydah Al-Jaza’iri” referenced in al-Suri’s diary refers to
    Barhoumi, or to some other Ubaydah al-Jaza’iri.
    We think record evidence amply supports the district
    court’s conclusion that “Ubaydah Al-Jaza’iri” and Barhoumi
    are one and the same person: al-Suri’s diary refers to
    “Ubaydah” as returning to the Pakistan guesthouse where al-
    Suri and Zubaydah were staying, and, shortly thereafter,
    Zubaydah and Barhoumi were in fact captured together in the
    same Pakistan guesthouse raid; al-Suri’s diary refers to
    “Ubaydah Al-Jaza’iri” as an explosives expert, and Barhoumi
    admitted to receiving instruction in the use and diffusion of
    landmines at multiple training camps; al-Suri’s diary
    describes “Ubaydah” as “one of the trainers at Khaldun,” and
    Barhoumi concedes that he trained at the Khaldan camp
    (though not that he was a trainer there). Barhoumi’s theory—
    that he is not the “Ubaydah” referred to in al-Suri’s diary—
    therefore must rest on the premise that there was a second
    Algerian staying with Zubaydah at the same Pakistan
    guesthouse who, like Barhoumi, also went by the alias
    Ubaydah al-Jaza’iri, was at the Khaldan camp, and trained in
    the use of landmines or explosives. Without hazarding a
    guess as to the probability of such a coincidence, we have
    little difficulty concluding that the district court did not
    clearly err in finding that “Ubaydah Al-Jaza’iri’b—
    Barhoumi’s admitted alias—in fact refers to Barhoumi.
    In sum, then, record evidence shows (1) that Barhoumi
    trained at the Khaldan camp, which was associated with
    Zubaydah; (2) that he was later captured along with Zubaydah
    in the same Pakistan guesthouse; and (3) that he functioned as
    a “Permanent” member of Zubaydah’s group who provided
    explosives training to other militia members “for operations
    20
    against the Americans inside of Afghanistan.” This evidence
    shows more than “mere sympathy” toward Zubaydah’s
    organization: al-Suri’s diary singles him out as a member of
    that organization, actively engaged in training other members.
    Hamlily, 616 F. Supp. 2d at 75 (quoting Gherebi v. Obama,
    
    609 F. Supp. 2d 43
    , 68 (D.D.C. 2009)). This certainly
    qualifies as “function[ing] and participat[ing] within or under
    the command structure of the organization,” id., and, contrary
    to Barhoumi’s argument, amounts to more than just “guilt by
    association” based on an “attenuated correlation in his travel
    patterns with Zubaydah and the mysterious al-Suri,”
    Appellant’s Br 37. We therefore conclude that all of this
    evidence, if reliable—a question we turn to in the next
    section~—is sufficient to sustain the district court’s
    determination that the United States is lawfully detaining
    Barhoumi under the AUMF.
    In reaching this conclusion, we emphasize that we have
    not relied on -’s diary. This obviates the need to
    determine whether, as Barhoumi contends, that diary is
    unreliable by virtue of _’s alleged mental illness, or
    whether, as the government argmes, the _ and al-Suri
    diaries serve to corroborate each other. Nor have we relied on
    interrogation statements made by another detainee, Benyam
    Muhammad, who identified Barhoumi as “Ubaida” and stated
    that Barhoumi was providing “Abu Muslim” and “Hatit” with
    electronics training at the Faisalabad guesthouse, but whom
    Barhoumi asserts is an unreliable source because he was
    allegedly rendered abroad and tortured some time prior to
    making these statements.
    Reliability 0fthe al-Suri Diary
    Although under Al—Bz‘hani and Awad hearsay evidence is
    always admissible in Guantanamo habeas proceedings, such
    evidence must be accorded weight only in proportion to its
    reliability. See Al—Bihani, 590 F.3d at 879 (“[T]he question a
    3
    This case concerns Sufyian Barhoumi, who was captured
    during the ensuing hostilities and has, pursuant to the AUMF,
    been held at the US. naval base in Guantanamo Bay, Cuba,
    for the last eight years. A 37-year-old Algerian citizen,
    Barhoumi left Algeria after completing high school and
    travelled throughout northern Africa and Europe, ultimately
    settling in London, where he lived for about two years. At his
    Combatant Status Review Tribunal (CSRT) and
    Administrative Review Board (ARB) hearings, Barhoumi
    recounted that while in London he attended a mosque where
    he saw films depicting Russian atrocities committed against
    Muslims in Chechnya. Inspired by these films, Barhoumi
    travelled to Karachi, Pakistan, and then to Jalalabad,
    Afghanistan, where he trained to fight alongside the Chechens
    in their struggle against the Russian government.
    By his own admission, Barhoumi trained at several
    military camps in Afghanistan. In 1999, he trained at a camp
    located between Jalalabad and Kabul, where he received
    instruction in the use of rifles, small arms, and landmines.
    While practicing mine diffusion, he lost four fingers and
    badly damaged his thumb when a landmine he had unearthed
    exploded in his left hand. After recovering from his injuries,
    Barhoumi trained at another camp, Khaldan, from 1999 to
    2000. Located in the Khowst region of eastern Afghanistan,
    the Khaldan camp was associated with Abu Zubaydah, a
    reputed terrorist leader who commanded his own fighting
    force and who figures prominently in this case. Although the
    Khaldan camp was not an al-Qaida facility, a government
    intelligence report states that Zubaydah had agreed with
    Usama bin Laden to coordinate training efforts and allow
    Khaldan recruits to join al-Qaida. According to the report,
    21
    habeas court must ask when presented with hearsay is not
    whether it is admissible—it is always admissible—but what
    probative weight to ascribe to whatever indicia of reliability it
    exhibits”). Barhoumi contends that the al—Suri diary is
    unreliable and that the district court therefore clearly erred in
    considering it. In pressing this argument, Barhoumi leans
    heavily on Parhat. Although we agree with Barhoumi that
    Parhat sets the guideposts for our inquiry into the reliability
    of the hearsay diary evidence, we disagree with his
    characterization of that case and with his assertion that Parhat
    dictates that the al-Suri diary is inherently unreliable.
    In Parhat, we reviewed a CSRT determination that the
    petitioner, a Chinese citizen of Uighur ethnicity, qualified as
    an enemy combatant because he was affiliated with a Uighur
    independence group “associated” with al-Qaida and the
    Taliban. The Tribunal’s conclusion rested almost entirely on
    hearsay statements contained in four classified intelligence
    documents—one from the State Department and three from
    the Department of Defense—regarding activities allegedly
    undertaken by the independence group. Although the CSRT
    procedures allowed for consideration of hearsay evidence, the
    intelligence documents relied on by the CSRT merely
    described activities as “having ‘reportedly’ occurred, [and] as
    being ‘said to’ or ‘reported to’ have happened.” Parhat, 532
    F.3d at 846. The documents did not state “who ‘reported’ or
    ‘said’ or ‘suspected’ those things. Nor [did] they provide any
    of the underlying reporting upon which the documents’
    bottom—line assertions [were] founded.” Id. at 846—47.
    Explaining that these deficiencies precluded both the Tribunal
    and the court from assessing the reliability of the assertions
    made in those documents, we set aside the CSRT’s enemy
    combatant determination, thus rejecting “the govemment’s
    contention that it can prevail by submitting documents that
    read as if they were indictments or civil complaints, and that
    simply assert as facts the elements required to prove that a
    22
    detainee falls within the definition of enemy combatant.” Id.
    at 850,
    According to Barhoumi, the al—Suri diary, like the
    intelligence reports at issue in Parhat, lacks sufficient indicia
    of reliability to justify the district court’s decision to rely on
    it. But the problem with the intelligence reports at issue in
    Parhat was that they failed to provide “any of the underlying
    reporting upon which the documents’ bottom-line assertions
    are founded,” thus inhibiting our ability to evaluate the
    reliability of those assertions. Id. at 846—47. Here, the diary,
    more than 65 pages of detailed observations recorded by a
    self—professed associate of both Zubaydah and Barhoumi, is
    the underlying reporting on which the government’s
    assertions are founded. Thus, unlike the situation we faced in
    Parhat, here we are “able to assess the reliability of [the]
    evidence ourselves” by evaluating the diary’s internal
    coherence as well as its consistency with uncontested record
    evidence, including Barhoumi’s own statements and the
    circumstances of his capture. 1d. at 848. Conducting that
    assessment, which was not possible in Parhat, we conclude
    that the al—Suri diary contains sufficient indicia of reliability
    to justify the district court’s reliance on it.
    To begin with, Barhoumi acknowledges that the diary
    was recovered in the  This provides
    independent verification of al-Suri’s diary entry, just a few
    days before their capture, that Zubaydah and Barhoumi were
    staying in the same Pakistan guesthouse, which, again,
    Barhoumi himself acknowledges. It also reduces any concern
    that the diary is a government fabrication. Further reinforcing
    its reliability, the diary refers accurately and in great detail to
    verifiable real-world events. For example, the diary paints a
    detailed portrait of the battle of Tora Bora, which al-Suri
    correctly reports as having taken place in December 2001.
    Al—Suri also makes reference to several key players in the
    war: he alludes to injuries sustained by Dr. Ayman al-
    23
    Zawahiri when fleeing Tora Bora at bin Laden’s behest;
    Mohamed Atta’s role as an “airplane hero” in the September
    11, 2001, attacks; Mullah Omar’s efforts to reconstitute the
    Taliban in the wake of the US. invasion; and the assumption
    of the presidency by Hamid Karzai, whom al-Suri refers to as
    a “carbon copy of the former King Zhahir Shah.” Of course,
    we recognize that al—Suri could have discovered this
    information from readily available news sources. Our only
    point is that al-Suri’s lengthy and highly detailed descriptions
    of real-world persons, places, and events tend to enhance the
    credibility of the diary as a whole.
    Furthermore, although it is true, as Barhoumi
    emphasizes, that the government has provided no information
    about al-Suri, the diary itself suggests that al-Suri possessed
    first-hand knowledge of Zubaydah and his organization. Al-
    Suri refers to himself as a “Permanent” member of
    Zubaydah’s militia who, like Barhoumi, had trained at the
    Khaldan camp. Al-Suri also demonstrates a familiarity with
    Zubaydah’s activities—not just his comings and goings, but
    also more intimate details such as where he sleeps and when
    he shaves. Indeed, the circumstances of the diary’s
    recovery
    reinforces
    the conclusion that al-Suri knew both Zubaydah and
    Barhoumi, thus enhancing the credibility of his depiction of
    Barhoumi’s role in Zubaydah’s organization.
    Barhoumi’s own statements further buttress the diary’s
    reliability. As noted above, Barhoumi admitted to being
    trained in mine diffusion; the diary refers to him as an
    explosives expert. Barhoumi admitted to training at the
    Khaldan camp; the diary refers to him as “one of the trainers
    at Khaldun.” The al-Suri diary is therefore a far cry from the
    “bare assertions” deemed unreliable in Parhat, 532 F.3d at
    847, as it possesses both endogenous and exogenous indicia
    of reliability.
    24
    Challenging this conclusion, Barhoumi argues that
    because the government chose to present the al-Suri diary as
    part of a “raw” intelligence report, Parhat compels us to
    conclude that it “‘lack[s] sufficient indicia of the statements’
    reliability’ to be reliable.” Appellant’s Br. 28—29 (quoting
    Parhat, 532 F.3d at 836). But nothing in Parhat establishes a
    per se rule that information contained in an intelligence report
    is inherently unreliable. Indeed, in Parhat we clarified that
    “we do not suggest that hearsay evidence is never reliable—
    only that it must be presented in a form, or with sufficient
    additional information, that permits . . . [the] court to assess
    its reliability.” 532 F.3d at 849. We also acknowledged that
    an intelligence report’s reliability can be assessed by
    comparison to “exogenous infonnation”—so long as such
    information is, in fact, available. Id. at 848. Even though the
    al—Suri diary is contained in an intelligence report, it
    represents a discrete piece of physical evidence, and the
    nature and reliability of that evidence is not altered just
    because it bears the label “intelligence.”
    Barhoumi also challenges the reliability of the al-Suri
    diary by pointing to alleged inconsistencies with -’s
    diary. As noted above, we have not relied on ’s
    diary to accept the district court’s conclusion that the
    evidence shows that it is more likely than not that Barhoumi
    was “part of” Zubaydah’s organization. Nevertheless, we
    cannot disregard Barhoumi’s claim of inconsistency, as any
    significant discrepancy between the diaries could serve to
    undermine the credibility of al—Suri’s diary as a whole.
    The primary inconsistency identified by Barhoumi
    relates to the diaries’ passages concerning Barhoumi’s alleged
    return from Tora Bora. The district court concluded that both
    diaries tell essentially the same story: that Barhoumi returned
    from Tora Bora and reported that 300 “brothers” engaged in
    battle there. The court made this assumption even though the
    relevant portion of —’s diary referred simply to a
    25
    “brother” as arriving from Tora Bora, while al-Suri cited
    “Ubaydah” as making that trip. Barhoumi complains that the
    government’s assertion that the two diaries refer to “the same
    person is pure speculation because _” provides
    neither a name nor any “other identifying information for the
    ‘brother.”’ Reply Br. 10. Reinforcing this argument,
    Barhoumi points out that, as the district court recognized,
    these diary entries are dated roughly three weeks apart:
    -’s is dated January 30, 2002; Al-Suri’s is dated
    February 21, 2002.
    We agree with Barhoumi that three weeks is too large a
    mismatch to support the district court’s conclusion that the
    diary entries depict the same event. That said, al—Suri’s diary
    includes another description of a “brother” arriving from Tora
    Bora that is more in line with _’s entry. Dated
    February 4, 2002, the al-Suri diary entry reports that “[a]fter
    breakfast, our brother Sulman al-Najdi (who came from Tora
    Bora) told us about a battle he witnessed.” Recounting the
    battle, al—Najdi reported that the “bombardment was
    accompanied with malicious attacks by the spiteful, the
    hypocrite and the collaborator Shi’a and the tribe of ((Hadrat
    ‘A1i)) who still is causing worries to the Taliban in
    Jalalabad.” This report is similar to -’s, dated just
    five days earlier, which recounts that the “brother” who came
    from Tora Bora described “the betrayal of some tribes and
    apostate commanders, such as (Hadrat Ali), may God afflict
    him with what he deserves,” In other words, both
    and al-Suri seem to recount the same story about a “brother”
    who arrived from Tora Bora and detailed the perceived
    betrayal suffered there at the hands of a hostile tribe—and
    that “brother” is not Barhoumi. Under this interpretation,
    then, the date discrepancy between the - and al—Suri
    entries describing the 300 fighters who remained at Tora Bora
    does nothing to undermine the reliability of al—Suri’s account;
    the dates differ simply because, as Barhoumi himself
    suggests, the reports stem from different sources. Only the al—
    26
    Suri diary refers to Barhoumi as arriving from Tora Bora, and
    _’s diary contains nothing that contradicts that
    account.
    Barhoumi’s remaining challenge to the reliability of the
    al—Suri diary is somewhat more troubling. He argues that the
    govemment’s refusal to make available a facsimile of the al-
    Suri diary in its original Arabic or to provide any information
    as to the qualifications or motives of its translator raises
    further doubts as to its reliability. In support, Barhoumi cites
    to a line of cases concerning the “language conduit rule,”
    which holds that “except in unusual circumstances, an
    interpreter is no more than a language conduit and therefore
    his translation does not create an additional level of hearsay.”
    United States v. Martinez—Gaytan, 
    213 F.3d 890
    , 892 (5th Cir.
    2000) (internal quotation marks omitted). Some courts have
    carved out a “narrow exception” to this rule “where the
    particular facts of a case cast significant doubt upon the
    accuracy of a translated confession.” United States v.
    Vidacak, 
    553 F.3d 344
    , 352 (4th Cir. 2009) (internal
    quotation marks omitted). Contending that this is just such a
    case, Barhoumi suggests that the same underlying reliability
    concerns that cause some courts to deem a translation to be
    hearsay means that the translation of al-Suri’s diary is
    unreliable. We disagree.
    As an initial matter, we note that the language conduit
    rule pertains to the question whether a translation, usually of a
    party—opponent’s statements, creates an additional level of
    hearsay and is thus inadmissible unless the translator testifies
    in court. Here, however, we have already crossed that bridge:
    the al—Suri diary is unquestionably hearsay, but nonetheless
    admissible as a matter of law pursuant to Al—Biham' and
    Awad. The question in this case, then, is not a binary one—
    admissibility vs. inadmissibility—but rather concerns the
    degree of reliability exhibited by the diary. Although we
    accept that the additional layer of hearsay added by the
    27
    diary’s translation renders it somewhat less reliable than it
    otherwise would be (particularly if the government had
    provided information regarding its translation), we
    nonetheless reject Barhoumi’s contention that the district
    court therefore clearly erred in relying on the diary.
    The only translation deficiencies alleged by Barhoumi
    spring from translator notations appearing in the section of
    the diary discussing Ubaydah Al-Jaza’iri’s description of his
    flight from Tora Bora. One such notation states as follows:
    “(TN: The following subparagraph presents text from the
    page numbered 56 by the Author. The page is undated, but
    seems to be a continuation of the entry begun on 21 February
    in subparagraph (ZZ) above)”. In part because these
    notations reflect some uncertainty as to whether the passage
    in question comes immediately after the report that Ubaydah
    arrived from Tora Bora, Barhoumi contends that there “is no
    indication whatsoever in the al—Suri Diary that the person
    describing the battle [in the subsequent passage] was
    ‘Ubaydah,”’ nor “that the person providing the report
    participated in the battle.” Reply Br. 13; see also Oral Arg.
    Tr. at 39—40 (suggesting that “gaps in the diaries” cast doubt
    on the Tora Bora account). But we need not accept the
    government’s assertion that Barhoumi fought at Tora Bora to
    sustain the district court’s conclusion that Barhoumi was “part
    of” Zubaydah’s militia; as Barhoumi himself concedes, it is
    sufficient for the government to show that he was “part of” an
    “associated force” engaged in hostilities against US. or
    coalition forces. See Al—Bihani, 590 F.3d at 872 (explaining
    that under the “part of” criterion, the President can lawfully
    detain “an individual who was part of . . . Taliban or al Qaeda
    forces, or associated forces that are engaged in hostilities
    against the United States or its coalition partners” (internal
    quotation marks omitted)). Thus, although it seems clear to
    us that the person describing the battle in al—Suri’s diary was
    in fact “Ubaydah,” any lack of clarity on that score is
    immaterial.
    28
    More generally, we reject Barhoumi’s suggestion that the
    translator’s forthrightness regarding uncertainties surrounding
    the date of particular diary entries somehow taints the
    reliability of the diary as a whole. If our analysis of the
    district court’s decision rested on al—Suri writing a particular
    passage on a particular date, the absence of a date on that
    page of the diary might well have significance. But al-Suri’s
    statement that Barhoumi is a “Permanent” member of
    Zubaydah’s militia is inculpatory regardless of the date on
    which that statement was made, and Barhoumi gives us little
    reason to suspect—nor does he even argue—that the
    translator erred in translating this portion of the diary.
    Indeed, Barhoumi’s only argument regarding the
    “membership list” passage is that the district court erred in
    concluding that he is the “Ubaydah Al—Jaza’iri” referred to in
    that entry—an argument we reject above.
    We understand Barhoumi’s frustration about the
    government’s steadfast refusal to provide any information
    regarding al-Suri or the circumstances surrounding the
    translation of his diary. Ultimately, however, our charge is to
    determine whether, based on the entirety of the evidence, the
    district court clearly erred in relying on the diaryhnot
    whether we would have accorded it different weight had we
    been sitting as trier of fact. See Awad, slip op at. 1415
    (considering “whether the district court, in light of all of the
    evidence, made an erroneous finding that [the detainee] was
    ‘part of” al Qaeda”). The diary was recovered in the
    ; its
    author displays first-hand knowledge of both Zubaydah and
    Barhoumi, as well as the operations of Zubaydah’s militia;
    and the diary bears numerous consistencies with Barhoumi’s
    own uncontested testimony and verifiable real~w0rld events.
    Given this, and notwithstanding some of the legitimate
    concerns raised by Barhoumi, we cannot say that we are “left
    with the definite and firm conviction that a mistake has been
    committed” by the district court in relying on the al-Suri
    29
    diary. Anderson, 470 US. at 573 (internal quotation marks
    omitted).
    IV.
    For the reasons set forth above, we detect no reversible
    error in the district court’s finding, based on the al-Suri diary,
    Barhoumi’s uncontested testimony, and the circumstances of
    his capture, that it is more likely than not that Barhoumi was
    “part of” an al-Qaida-associated force and therefore properly
    detained pursuant to the AUMF. We therefore affirm the
    district court’s denial of Barhoumi’s petition for a writ of
    habeas corpus.
    S0 ordered.

    At the Khaldan camp, Barhoumi received additional
    small arms training, as well as instruction in tactical
    movement, navigation, artillery, mortars, radio
    communication, and military tactics used in Chechnya.
    Barhoumi left Khaldan in May 2000, but unable to make it to
    Chechnya——crossing the border apparently proved too
    dangerous—Barhoumi shuttled between a series of
    guesthouses in Kabul, Khandahar, and Jalalabad. Although
    the government claims he provided military training to others
    at these guesthouses, Barhoumi denied doing so, insisting that
    he spent this time teaching children the Koran and Arabic.
    Barhoumi admitted that he received additional antipersonnel
    mine instruction at another training camp during this period,
    though he later backtracked, claiming that he trained at only
    two military camps in Afghanistan, not three.
    After US. and coalition forces commenced military
    action in Afghanistan, Barhoumi decided to leave the country.
    At some point in late fall of 2001 (the precise timing is
    disputed), Barhoumi fled Afghanistan through the mountains
    into Pakistan, initially staying at a guesthouse in Waziristan,
    the mountainous region along the border, and then moving on
    to various guesthouses in Peshawar and Lahore. In his ARB
    hearing, Barhoumi testified that he travelled to a guesthouse
    in Faisalabad, Pakistan, in February 2002. Approximately ten
    days after he arrived there, Pakistani police officers raided the
    house and arrested him—along with Abu Zubaydah, who was
    also staying at the Faisalabad guesthouse. In May 2002, the
    US. military took Barhoumi into custody and transferred him
    to Guantanamo, where he has been detained ever since. Abu
    Zubaydah is also being held at the Guantanamo naval base.
    In July 2005, Barhoumi filed a petition for a writ of
    habeas corpus in the US. District Court for the District of
    Columbia. Although the district court granted the
    government’s motion to dismiss on the ground that section 7
    of the Military Commissions Act of 2006 (MCA), 28 U.S.C. §
    5
    2241(e), deprived the court of jurisdiction over habeas claims
    brought by aliens detained as enemy combatants, it later
    vacated that dismissal in light of the Supreme Court’s
    decision in Boumediene v. Bush, 
    128 S. Ct. 2229
     (2008).
    There the Supreme Court held that the constitutional privilege
    of habeas corpus extends to aliens detained at Guantanamo
    and struck down the MCA’s jurisdiction-stripping provision
    as an unconstitutional suspension of the writ.
    Following Boumediene, the judges of the district court,
    meeting in executive session, decided to coordinate
    proceedings in most Guantanamo habeas cases, including
    Barhoumi’s. In re Guantanamo Bay Detainee Ling, Misc.
    No. 08-442 (D.D.C. July 2, 2008). On November 6, 2008,
    Judge Hogan, the coordinating judge, issued a Case
    Management Order governing the consolidated proceedings.
    In re Guantanamo Bay Detainee Litig, Misc. No. 08-442,
    
    2008 WL 4858241
     (D.D.C. Nov. 6, 2008) (“CMO”). The
    CMO provided, among other things, that (1) individual judges
    hearing habeas corpus petitions may admit and consider
    hearsay evidence, and (2) the government bears the burden of
    proving by a preponderance of the evidence that the
    petitioner’s detention is lawful. 1d,, 
    2008 WL 4858241
     at *3.
    Ruling from the bench, the district judge hearing
    Barhoumi’s petition explained that the AUMF authorized the
    President “to detain persons who were part of[,] or
    substantially supported, Taliban or al Qaida forces or
    associated forces that are engaged in hostilities against the
    United States or its coalition partners, including any person
    who has committed a belligerent act or has directly supported
    hostilities in aid of such enemy armed forces.” Hr’ g Tr. at 4,
    Barhoumi v. Obama, No. 05-1506 (D.D.C. Sept. 3, 2009).
    Applying this standard, the court concluded that Barhoumi
    was properly detained and therefore denied his habeas
    petition.
    6
    In reaching this conclusion, the district court relied on
    Barhoumi’s own testimony in the CSRT and ARB
    proceedings, as well as on two diaries recovered at the
    The first of these diaries was authored by
    The second was written by one Abu
    Kamil al-Suri, who claimed in his diary to be a member of
    Zubaydah’s militia. Although the record does not contain the
    al-Suri diary itself, it does contain an intelligence report that
    includes an English translation of the diary. In his diary, al-
    Suri described staying in a guesthouse in Pakistan along with
    Zubaydah and a person identified as “Ubaydah Al-Jaza’iri,”
    which the district court concluded referred to Barhoumi, who
    had admitted to using that alias. The court observed that “the
    travel pattern of Mr. Barhoumi[,] as he describes it, is
    consistent with the travel pattern of Mr. Zubaydah and Mr. a1
    Suri,” as described in the - and al-Suri diaries: “each
    of them started in Afghanistan, crossed mountains into
    Pakistan, moved through Pakistan, went to Lahore and ended
    up in Faisalabad where they were arrested together.” Id. at 5.
    The district court also relied on the two diaries’
    descriptions of fighting at Tora Bora, the cave complex in the
    mountains of eastern Afghanistan where Taliban and al—Qaida
    fighters—reportedly including bin Laden—holed up after the
    commencement of hostilities and were besieged by US. and
    coalition forces. According to _’s diary, after the
    beginning of the war Zubaydah fled to Waziristan to help
    fighters escape from Tora Bora. Al—Suri recounts in his diary
    that “[i]n the evening, ‘Ubaydah Al-Jaza’iri, one of the
    trainers at Khaldun[,] came in from Tora Bora” and reporte
    that “300 of the brothers were gathered” there. _’s
    diary similarly refers to “one of our brothers who came from
    (Tora Bora)” and who reported that “300 brothers” fought
    there. Given the consistency of these diary entries, the district
    court determined that Barhoumi was in fact the person
    7
    referred to in both diaries as coming from Tora Bora to the
    Pakistan guesthouse where Zubaydah was staying.
    Based on all this evidence, the district court concluded
    that Barhoumi was “part of” Zubaydah’s militia—an
    “associated force that was engaged in hostilities against the
    United States or its coalition partners”—and therefore
    lawfully detained pursuant to the AUMF. Hr’ g Tr. at 12.
    Barhoumi now appeals the district court’s denial of his habeas
    petition. In considering this appeal, we have benefitted from
    the superb briefs and excellent oral argument by counsel for
    both parties.
    II.
    We begin with two threshold legal issues. Barhoumi
    argues that the district court erred in admitting into evidence
    the al-Suri and - diaries, which are hearsay. See
    FED. R. EVID. 801(0). He further argues that the district court
    should have applied a clear and convincing evidence standard
    of proof rather than a preponderance standard. We consider
    each issue in turn.
    The Diaries
    Barhoumi contends that in admitting the diaries, the
    district court adjudicating his habeas petition failed to comply
    with the CMO, which set forth the following procedures
    regarding the admission of hearsay evidence:
    On motion of either the petitioner or the government,
    the Merits Judge may admit and consider hearsay
    evidence that is material and relevant to the legality
    of the petitioner’s detention if the movant establishes
    that the hearsay evidence is reliable and that the
    provision of nonhearsay evidence would unduly
    burden the movant or interfere with the
    8
    government’s efforts to protect national security.
    The proponent of hearsay evidence shall move for
    admission of the evidence no later than 7 days prior
    to the date on which the initial briefs for judgment
    on the record are due.
    CMO, 
    2008 WL 4858241
     at *3 (internal citation omitted).
    Barhoumi points out that the government never timely filed a
    motion specifically requesting admission of the diaries, as
    required by the CMO. Rather, the government submitted a
    memorandum in which it made general assertions regarding
    the admission and reliability of hearsay evidence in all the
    Guantanamo detainee cases, but made no mention of the
    diaries or any other evidence in specific connection to
    Barhoumi’s factual return. Later, after the deadline
    established in the CMO had passed, the government filed a
    motion in Barhoumi’s case to supplement the record with the
    diaries. The district court admitted all the hearsay evidence,
    including the two diaries, explaining:
    Because these Guantanamo proceedings are unique
    and difficult, I have decided to receive and consider
    all of the evidence offered by both sides, but have
    assessed it item by item for consistency[,] the
    conditions in which the statements were made and
    the documents found. The personal knowledge of
    the declarant and the levels of hearsay. I have given
    the evidence the weight I think it deserves.
    Hr’g Tr. at 4.
    Barhoumi argues that the district court’s decision
    violated the CMO not only because the government failed to
    timely move to admit the diary evidence (according to
    Barhoumi, the generic hearsay memorandum, though timely,
    failed to qualify as a motion to admit the diaries), but also
    because the government never demonstrated that “the
    9
    provision of nonhearsay evidence would unduly burden the
    movant or interfere with the government’s efforts to protect
    national security,” as the CMO required. CMO, 
    2008 WL 4858241
     at *3. Quoting the Federal Circuit, Barhoumi states
    that “parties must understand that they will pay a price for
    failure to comply strictly with scheduling and other orders,
    and that failure to do so may properly support severe
    sanctions and exclusions of evidence.” Appellant’s Br. 20
    (quoting 02 Micro Int ’1 Ltd. v. Monolithic Power Sys., Inc,
    
    467 F.3d 1355
    , 1369 (Fed. Cir. 2006)) (internal quotation
    marks omitted); see also Rosario—Diaz v. Gonzalez, 140 F .3d
    312, 315 (lst Cir. 1998) (“[L]itigants have an unflagging duty
    to comply with clearly communicated case-management
    orders”). Given this, Barhoumi argues, the district court’s
    alleged failure to comply with the CMO in and of itself
    constitutes grounds for reversal. We disagree.
    Although the cases Barhoumi cites hold that parties have
    a duty to comply with case management orders, he cites no
    authority for the proposition that judges are required to follow
    their own*much less another judge’s—case management
    order. In any event, the CMO governing the Guantanamo
    habeas cases expressly authorizes judges assigned to
    adjudicate habeas petitions to “alter the framework [set out in
    the CMO] based on the particular facts and circumstances of
    their individual cases.” CMO, 
    2008 WL 4858241
     at *1 n.l.
    That is precisely what the district court did here. Citing the
    “unique and difficult” circumstances inherent in the
    Guantanamo proceedings, the district court decided—after
    giving Barhoumi an opportunity to respond to the
    govemment’s motion to supplement the record—that the
    circumstances of Barhoumi’s case justified admitting all
    hearsay evidence. Hr’ g Tr. at 4. Other district judges have
    made the same determination in similar circumstances. See,
    e.g., Awad v. Obama, 
    646 F. Supp. 2d 20
    , 23 (D.D.C. 2009)
    (receiving all evidence offered by either side but assessing it
    “item-by—item for consistency, the conditions in which
    10
    statements were made and documents found, the personal
    knowledge of a declarant, and the levels of hearsay”). We
    therefore conclude that the district court did not abuse its
    discretion in departing from the CMO’s procedural
    framework regarding the admissibility of hearsay. See Potter
    v. District of Columbia, 
    558 F.3d 542
    , 546 (DC. Cir. 2009)
    (case management decisions reviewed for abuse of
    discretion).
    Barhoumi next contends that irrespective of the district
    court’s fidelity to the CMO, the court erred in admitting the
    diaries absent a demonstration by the government that they
    fall within an established hearsay exception in the Federal
    Rules of Evidence. This argument, however, runs counter to
    this court’s decision in Al-Bihani v. Obama, 
    590 F.3d 866
    (DC. Cir. 2010), another Guantanamo habeas case in which
    the detainee also challenged the district court’s admission of
    hearsay evidence. Relying in part on the Supreme Court’s
    suggestion in Hamdi v. Rumsfeld, 542 US. 507, 533—34
    (2004), that hearsay “may need to be accepted as the most
    reliable available evidence” in enemy combatant proceedings,
    the court stated that “the question a habeas court must ask
    when presented with hearsay is not whether it is admissible—
    it is always admissible—but what probative weight to ascribe
    to whatever indicia of reliability it exhibits,” AZ—Bihani, 590
    F.3d at 879 (emphasis added).
    Barhoumi seeks to sidestep this language by
    characterizing it as mere dicta that is “neither binding nor
    persuasive.” Appellant’s Br. 20. Since oral argument in this
    case, however, another panel of this court has squarely
    foreclosed his theory. In Awad v. Obama, No. 09-5351 (DC.
    Cir. June 2, 2010), the panel explained that Al—Bihani stands
    for the proposition that “hearsay evidence is admissible in this
    type of habeas proceeding if the hearsay is reliable.” Id., slip
    op. at 11. “We, of course, are without authority to overturn a
    decision by a prior panel of this Court.” La. Pub. Serv.
