Judicial Activity Concerning Enemy Combatant Detainees: Major Court Rulings

Summary
As part of the conflict with Al Qaeda and the Taliban, the United States has captured and detained
numerous persons believed to have been part of or associated with enemy forces. Over the years,
federal courts have considered a multitude of petitions by or on behalf of suspected belligerents
challenging aspects of U.S. detention policy. Although the Supreme Court has issued definitive
rulings concerning several legal issues raised in the conflict with Al Qaeda and the Taliban, many
others remain unresolved, with some the subject of ongoing litigation.
This report discusses major judicial opinions concerning suspected enemy belligerents detained in
the conflict with Al Qaeda and the Taliban. The report addresses all Supreme Court decisions
concerning enemy combatants. It also discusses notable circuit court opinions addressing issues
of ongoing relevance. In particular, it summarizes notable decisions which have (1) addressed
whether the Executive may lawfully detain only persons who are “part of” Al Qaeda, the Taliban,
and affiliated groups, or also those who provide support to such entities in their hostilities against
the United States and its allies; (2) adopted a functional approach for assessing whether a person
is “part of” Al Qaeda; (3) decided that a preponderance of evidence standard is appropriate for
detainee habeas cases, but suggested that a lower standard might be constitutionally permissible,
and instructed courts to assess the cumulative weight of evidence rather than each piece of
evidence in isolation; (4) determined that Guantanamo detainees have a limited right to challenge
their proposed transfer to foreign custody, but denied courts the authority to order detainees
released into the United States; (5) held that the constitutional writ of habeas does not extend to
noncitizen detainees held at U.S.-operated facilities in Afghanistan; and (6) determined that
Guantanamo detainees may challenge conditions of their detention. Finally, the report discusses a
few criminal cases involving persons who were either involved in the 9/11 attacks or were
captured abroad by U.S. forces or allies during operations against Al Qaeda, the Taliban, and
associated entities, as well as reviews of military commission cases in federal appellate courts.
For over a decade, the primary legal authority governing the detention of enemy belligerents in
the conflict with Al Qaeda was the 2001 Authorization for Use of Military Force (“AUMF,” P.L.
107-40). In December 2011, Congress passed the National Defense Authorization Act for FY2012
(“2012 NDAA,” P.L. 112-81), which contains a provision that is largely intended to codify the
current understanding of the detention authority conferred by the AUMF, as has been interpreted
and applied by the Executive and the D.C. Circuit. In any event, the act does not address many of
the legal issues involving wartime detention that have not been squarely resolved by the Supreme
Court. Among other things, these unresolved issues include the precise scope of the Executive’s
wartime detention authority, including the circumstances in which U.S. citizens may be detained;
the degree to which noncitizens (or in one case, U.S. citizens) held abroad are entitled to
protections under the Constitution; the authority of federal habeas courts to compel the release
into the United States of detainees determined to be unlawfully held; and the ability of detainees
to receive advance notice and to challenge their proposed transfer to foreign custody.
Several rulings addressed in this report are discussed in greater detail in other CRS products,
including CRS Report RL33180, Enemy Combatant Detainees: Habeas Corpus Challenges in

Judicial Activity Concerning Enemy Combatant Detainees: Major Court Rulings

A

s part of the conflict with the Taliban and Al Qaeda, the United States has captured and
detained numerous persons believed to have been part of or associated with enemy
forces. Over the years, federal courts have considered a multitude of petitions by or on
behalf of suspected belligerents challenging aspects of U.S. detention policy. The Supreme Court
has issued definitive rulings concerning several legal issues raised in the conflict with Al Qaeda
and the Taliban, including executive authority under the 2001 Authorization for Use of Military
Force (“AUMF,” P.L. 107-40) to detain properly designated enemy belligerents captured on the
Afghan battlefield; the application of at least some provisions of the 1949 Geneva Conventions to
the conflict with Al Qaeda; and the ability of detainees held in the United States or at the U.S.
Naval Station in Guantanamo Bay, Cuba, to challenge the legality of their detention in habeas
corpus proceedings.
In December 2011, Congress passed the National Defense Authorization Act for FY2012 (“2012
NDAA,” P.L. 112-81), which contains a provision largely intended to codify the present
understanding of the detention authority conferred by the AUMF, as interpreted and applied by
the Executive and the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit).1
The full implications of the 2012 NDAA upon judicial activity concerning wartime detention
remains to be seen. In any event, the act does not address many of the legal issues involving
wartime detention which, while occasioning significant political debate, have not been squarely
resolved by the Supreme Court. These issues include the full scope of the Executive’s detention
authority, including the circumstances in which U.S. citizens may be detained as enemy
belligerents; the degree to which noncitizens held at Guantanamo and other locations outside the
United States are entitled to protections under the Constitution; the authority of federal habeas
courts to compel the release into the United States of detainees determined to be unlawfully held
if the Executive cannot effectuate their release to another country; and the ability of detainees to
receive advance notice and challenge their proposed transfer to a foreign country. Additionally,
the Supreme Court may be called upon to determine the nature of procedural rules to be applied
in habeas cases and the proper standard of evidence to be applied. To the extent that these rules
are found to differ from the Federal Rules of Civil Procedure and other court rules, it may be
necessary to determine whether the same procedural rules apply to both U.S. citizens and foreign
nationals who may be detained under the AUMF authority.
This report briefly summarizes major judicial opinions concerning suspected enemy belligerents2
detained in the conflict with Al Qaeda and the Taliban. It discusses all Supreme Court decisions
concerning enemy combatants. It also addresses notable appeals court opinions addressing issues
of ongoing relevance to U.S. detention policy. The report also discusses a few notable decisions
by federal district courts, including criminal cases involving persons who were either involved in

who might be subject to detention or prosecution in connection with the conflict authorized by the AUMF as
interpreted by the executive branch.

Supreme Court Decisions
Since 2004, the Supreme Court has made several rulings concerning enemy combatants. These
have addressed, inter alia, the Executive’s authority to detain enemy belligerents under the 2001
AUMF; the legality of military commissions established by presidential order to try suspected
belligerents for violations of the law of war; and detainees’ access to federal courts.

Hamdi v. Rumsfeld, 542 U.S. 507 (2004)3
The Hamdi case addressed the President’s authority to detain “enemy combatants” as part of the
conflict authorized by the AUMF, and whether a detained individual could seek independent
review of the legality of his detention. Four separate opinions were written, with none receiving
support of a majority of the Justices. However, a majority of the Court recognized that, as a
necessary incident to the 2001 AUMF, the President is authorized to detain persons captured
while fighting U.S. forces in Afghanistan (including U.S. citizens), and potentially hold such
persons for the duration of the conflict to prevent their return to hostilities.4 A divided Court
found that persons deemed “enemy combatants” have the right to challenge the legality of their
detention before a judge or other “neutral decision-maker,” with a majority of the Justices clearly
recognizing the existence of such a right in the case of a detained U.S. citizen.5
In a plurality opinion joined by three other Justices, Justice O’Connor wrote that a citizen
detained as an enemy combatant must receive notice of the factual basis for his classification and
a fair opportunity to rebut the government’s factual assertions before a neutral decision-maker,
and has a right to counsel in connection with such a hearing. The plurality suggested, however,
that the exigencies of the circumstances of a detainee’s capture may allow for a tailoring of

enemy combatant proceedings “to alleviate their uncommon potential to burden the Executive at
a time of ongoing military conflict,” possibly allowing hearsay evidence and “a presumption in
favor of the Government’s evidence,” as long as a fair opportunity to rebut such evidence is
provided.6

Rumsfeld v. Padilla, 542 U.S. 426 (2004)7
The Padilla case, decided on the same day as Hamdi, concerned a habeas challenge by Jose
Padilla, a U.S. citizen who was designated as an “enemy combatant” and militarily detained in the
United States for his alleged involvement in an Al Qaeda plot to detonate a “dirty bomb.” Unlike
the petitioner in Hamdi, who was captured in the Afghan zone of combat, Padilla was captured on
U.S. soil. In a 5-4 ruling, the Court remanded the case without deciding the merits on the ground
that Padilla’s habeas petition had not been filed in the proper venue. In doing so, the majority did
not reach the merits of Padilla’s claim that any authority the President might have under the
AUMF to detain “enemy combatants” did not extend to persons captured on American soil and
away from the Afghan battlefield. Four Justices would have found jurisdiction based on the
“exceptional circumstances” of the case and affirmed the holding below that detention is
prohibited under the Non-Detention Act, 18 U.S.C. §4001(a) (prohibiting the detention of U.S.
citizens unless authorized by an act of Congress). Padilla filed a new petition in the Fourth
Circuit, and the appellate court considered the legality of his detention in Padilla v. Haft,
discussed infra.

Rasul v. Bush, 542 U.S. 466 (2004)8
In Rasul v. Bush, the Court held in a 6-3 ruling that the federal habeas corpus statute, 28 U.S.C.
§2241, provided federal courts with jurisdiction to consider habeas corpus petitions by or on
behalf of persons detained at the U.S. Naval Station in Guantanamo Bay, Cuba. Having found that
Guantanamo detainees were entitled by statute to seek habeas review of their detention, the Court
did not reach the issue of whether the constitutional writ of habeas also extended to noncitizens
held at Guantanamo. The Court also did not address whether a less rigorous burden of proof or
relaxed evidentiary procedures would be appropriate in comparison to ordinary habeas cases.
Congress subsequently attempted to limit the reach of the federal habeas statute to Guantanamo
detainees through the enactment of the Detainee Treatment Act of 2005 (DTA)9 and the Military
Commissions Act of 2006 (MCA).10

Judicial Activity Concerning Enemy Combatant Detainees: Major Court Rulings

Hamdan v. Rumsfeld, 548 U.S. 557 (2006)11
In Hamdan v. Rumsfeld, the Supreme Court reviewed the validity of military tribunals established
pursuant to presidential order to try suspected terrorists for violations of the law of war. The
petitioner Hamdan was charged with conspiracy to commit a violation of the law of war. Prior to
reaching the merits of the case, the Hamdan Court first had to determine whether the DTA
stripped it of jurisdiction to review habeas corpus challenges by or on behalf of Guantanamo
detainees whose petitions had already been filed prior to enactment of the DTA. In a 5-3 opinion,
the Court held that the DTA did not apply to such petitions. Turning to the merits of the case, the
majority held that the convened tribunals did not comply with the Uniform Code of Military
Justice (UCMJ) or the law of war, as incorporated in the UCMJ and embodied in the 1949
Geneva Conventions, which the Court held applicable to the armed conflict with Al Qaeda. The
Court concluded that, at a minimum, Common Article 3 of the Geneva Conventions applies to
persons captured in the conflict with Al Qaeda, according to them a minimum baseline of
protections, including protection from the “passing of sentences and the carrying out of
executions without previous judgment pronounced by a regularly constituted court, affording all
the judicial guarantees which are recognized as indispensable by civilized peoples.” The Court
held that military commissions were not “regularly constituted” because they deviated too far
from the rules that apply to courts-martial, without a satisfactory explanation of the need for
departing from such rules. In particular, the Court noted that the commission rules allowing the
exclusion of the defendant from attending portions of his trial or hearing some of the evidence
against him deviated substantially from court-martial procedures.
A four-Justice plurality of the Court also recognized that for an act to be triable under the
common law of war, the precedent for it being treated as an offense must be “plain and
unambiguous.”12 After examining the history of military commission practice in the United States
and internationally, the plurality further concluded that conspiracy to violate the law of war was
not in itself a crime under the common law of war or the UCMJ.

Boumediene v. Bush, 553 U.S. 723 (2008)13
In the aftermath of the Hamdan decision, Congress enacted the MCA, which, inter alia, expressly
eliminated court jurisdiction over all pending and future causes of action other than via the
limited review permitted under the DTA. In the 2008 case of Boumediene v. Bush, the Court ruled
in a 5-4 opinion that the constitutional privilege of habeas extends to Guantanamo detainees. In
doing so, the Court stated that the Constitution’s extraterritorial application turns on “objective
factors and practical concerns.”14 The Court deemed at least three factors to be relevant in
assessing the extraterritorial scope of the constitutional writ of habeas: (1) the citizenship and
status of the detainee and the adequacy of the status determination process; (2) the nature of the

site where the person is seized and detained; and (3) practical obstacles inherent in resolving the
prisoner’s entitlement to the writ.
The Court also found that MCA §7, which limited judicial review of executive determinations of
the Boumediene petitioners’ enemy combatant status to that authorized by the DTA, did not
provide an adequate habeas substitute and therefore acted as an unconstitutional suspension of the
writ of habeas corpus. The majority listed a number of potential constitutional infirmities in the
DTA review process, including the absence of provisions (1) empowering a reviewing court to
order the release of a detainee found to be unlawfully held; (2) permitting petitioners to challenge
the President’s authority to detain them indefinitely; (3) enabling a presiding court to review or
correct administrative findings of fact which formed the legal basis for an individual’s detention;
and (4) permitting the detainee to present exculpatory evidence discovered after the conclusion of
administrative proceedings.
Although the Boumediene Court held that the constitutional writ of habeas extends to noncitizens
held at Guantanamo, it did not opine as to the scope of habeas review available to detainees, the

to which other constitutional provisions extend to noncitizens held at Guantanamo and elsewhere.

Gates v. Bismullah, 554 U.S. 913 (2008)
Prior to the Supreme Court’s decision in Boumediene, the D.C. Circuit considered a number of
challenges brought under the DTA in which detainees contested determinations by Combatant
Status Review Tribunals (CSRTs) that they were properly detained as enemy combatants. In 2008,
the government petitioned the Supreme Court to review two rulings by the D.C. Circuit regarding
the scope of judicial review of CSRT determinations.15 The Supreme Court granted certiorari and
vacated the appellate court’s decisions, remanding for reconsideration in light of the Supreme
Court’s decision in Boumediene. Upon remand, the D.C. Circuit reinstated without explanation its
decisions, presumably because it did not find the Boumediene ruling to conflict with its decisions
in these cases.

Al-Marri v. Spagone, 555 U.S. 1220 (2009)
In December 2008, the Supreme Court granted certiorari to review an en banc ruling by the U.S.
Court of Appeals for the Fourth Circuit (Fourth Circuit) regarding petitioner al-Marri, an alien
lawfully admitted into the United States on a student visa who had been arrested by civilian law
enforcement and thereafter transferred to military custody for detention as an enemy combatant.
At the time, the Court’s decision to review the Fourth Circuit’s ruling was thought to have
potentially set the stage for a definitive pronouncement regarding the President’s authority to
militarily detain terrorist suspects apprehended away from the Afghan battlefield. However,
before the Court could consider the merits of the case, the government requested that the Court

The D.C. Circuit in July 2007 issued an order rejecting the government’s motion to limit the scope of the court’s
review to the official record of the CSRT hearings. Bismullah v. Gates, 501 F.3d 178 (Bismullah I). The circuit court
decided that in order to determine whether a preponderance of evidence supported the CSRT determinations, it must
have access to all the information a CSRT is “authorized to obtain and consider, pursuant to the procedures specified by
the Secretary of Defense.” The court thereafter denied the government’s request for rehearing, explaining its view that
its previous order would not require a search for information that was not “reasonably available.” Bismullah v. Gates,

authorize al-Marri’s release from military custody and transfer to civilian authorities to face
criminal charges. The Court granted the government’s request, vacated the appellate court’s
earlier judgment, and transferred the case back to the lower court with orders to dismiss it as
moot. The appellate court’s ruling is discussed in more detail below.

Kiyemba v. Obama, 559 U.S. 131 (2010)
In October 2009, the Supreme Court agreed to review a ruling by a three-judge panel of the D.C.
Circuit in the case of Kiyemba v. Obama, discussed infra. The Kiyemba case involved several
Guantanamo detainees who, despite no longer being considered enemy combatants and having
been cleared for release, had not been transferred from Guantanamo on account of the
government being unable to effectuate their release to a foreign country. The Kiyemba petitioners
sought reversal of a D.C. Circuit ruling finding that a federal habeas court lacked the authority to
compel the Executive to release the detainees into the United States. Following the Supreme
Court’s grant of certiorari, however, several Kiyemba petitioners were resettled in foreign
countries, and the United States was able to find countries willing to settle the remaining
petitioners, although five petitioners rejected these countries’ offers for resettlement. On March 1,
2010, the Supreme Court vacated the appellate court’s opinion and remanded the case in light of
these developments. Because the Supreme Court had granted certiorari on the understanding that
no remedy was available for the petitioners other than release into the United States, it returned
the case to the D.C. Circuit to review the ramifications of the new circumstances. Discussion of
subsequent action taken by the D.C. Circuit, as well as by the Supreme Court with respect to
another petition for certiorari by the Kiyemba petitioners, is found below.

Kiyemba v. Obama, 131 S. Ct. 1631 (2011)
Following the Supreme Court’s remand of the Kiyemba case back to the D.C. Circuit, the circuit
panel reinstated its opinion with slight modifications. The Kiyemba petitioners once again sought
Supreme Court review of the circuit court’s ruling that federal habeas courts lacked authority to
compel the petitioners’ release into the United States. On April 18, 2011, the Supreme Court
denied their request for review. Eight Supreme Court Justices took part in the decision, with
Justice Kagan recusing herself. In joining the opinion, Justice Breyer issued a statement joined by
Justices Kennedy, Ginsburg, and Sotomayor, which emphasized that the issue that had initially
been presented when the Kiyemba petitioners first sought review by the Supreme Court was
“whether a district court may order the release of an unlawfully held prisoner into the United
States where no other remedy is available.” Because the government had received offers of
resettlement for the petitioners, the petitioners had not proffered or alleged evidence that they
would face torture or other harm, and the government continued to seek plaintiffs’ resettlement,
Justice Breyer found “no Government-imposed obstacle to petitioners’ timely release and
appropriate resettlement.” However, Justice Breyer stated that should these circumstances
materially change, the petitioners “may of course raise their original issue (or related issues)
again in the lower courts and in this Court.”

constitutional writ of habeas corpus extends to detainees held at Guantanamo, over 200 habeas
petitions were filed by detainees in the U.S. District Court for the District of Columbia. Courts
considering habeas claims have sometimes reached differing conclusions regarding the scope of
the Executive’s detention authority; the admissibility of hearsay evidence and involuntary
statements made by detainees; the appropriate methodology for assessing the sufficiency and
reliability of evidence proffered by the government to justify the legality of a habeas petitioner’s
detention; and the remedy available for those persons whom a habeas court determines to have
been unlawfully detained.16 Decisions by the D.C. Circuit have generally been favorable to the
legal positions advanced by the government. Since 2009, the appellate court has issued rulings
concluding, among other things, that
•

the Executive may lawfully detain persons who are “part of” Al Qaeda, the
Taliban, and affiliated groups, and possibly also persons who provide a sufficient
degree of support to such entities in their hostilities against the United States and
its allies (Al-Bihani v. Obama);

•

a functional approach is appropriate when assessing whether a person is “part of”
Al Qaeda, meaning that judges should consider the significance of a person’s
activities in relation to the organization, rather than requiring formal proof of
membership, such as evidence the petitioner received orders from the
organization’s hierarchy (Awad v. Obama, Bensayah v. Obama, Salahi v. Obama);

•

the government may satisfy its evidentiary burden in support of a person’s
detention when its factual claims are supported by a preponderance of evidence
(Al-Bihani v. Obama, Al Odah v. United States), but a lower standard might be
constitutionally permissible (Al-Adahi v. Obama, Almerfedi v. Obama);

•

it is proper for a habeas court to assess the cumulative weight and effect of
proffered evidence according to a “conditional probability analysis” when
determining whether the government has demonstrated factual grounds for
detaining a habeas petitioner (Al-Adahi v. Obama, Salahi v. Obama);

•

consideration of hearsay evidence in habeas cases is not determined by the
Federal Rules of Evidence (Al Odah v. United States, Al-Madhwani v. Obama);

•

official government records, including government intelligence reports, are
entitled to a presumption of regularity in Guantanamo habeas litigation (Latif v.
Obama);

•

the writ of habeas affords Guantanamo detainees with a limited right to challenge
their proposed transfer to the custody of a foreign government (Kiyemba II) as
well as matters related to their conditions of confinement (Aamer v. Obama,
Hatim v. Obama);

•

habeas courts lack authority, absent an authorizing statute, to compel the
Executive to release non-citizen detainees into the United States, even if such
persons have been determined by the court to be unlawfully detained (Kiyemba I
and III);

•

it is unlikely that noncitizens who have been transferred to foreign custody may
seek judicial review of their designation as enemy combatants by the U.S.
government (Gul v. Obama); and

•

the constitutional writ of habeas does not presently extend to noncitizen detainees
held at U.S.-operated facilities in Afghanistan (Maqaleh v. Gates).

In some of these cases, affected detainees have requested Supreme Court review. Several of these
requests have been denied. It remains to be seen whether the Supreme Court will ultimately agree
to review any of the D.C. Circuit’s decisions, or whether the appellate court’s rulings will remain
controlling for the foreseeable future.
The following section discusses major rulings made by the D.C. Circuit regarding persons
designated as enemy combatants that involve matters of continuing relevance to U.S. detention
policy. It does not discuss those rulings that were subsequently overruled by the Supreme Court
on the merits.

Scope of Executive’s Detention Authority and Related
Evidentiary Burdens
The D.C. Circuit has issued several opinions relating to the scope of the Executive’s authority to
detain persons as part of the conflict with Al Qaeda, the Taliban, and associated forces. These
opinions have also addressed the issues related to the sufficiency and reliability of evidence
proffered by the government in support of its factual claims.

Al-Bihani v. Obama, 590 F.3d 866, en banc rehearing denied,
619 F.3d 1 (D.C. Cir. 2010), cert. denied, 131 S. Ct. 1814 (2011)
In January 2010, a three-judge panel of the D.C. Circuit issued a ruling concerning the scope of
the government’s detention authority under the AUMF in the case of Al-Bihani v. Obama. In an
opinion supported in full by two members of the panel,17 the appellate court recognized that, at a
minimum, the President was authorized to detain persons who were subject to the jurisdiction of
military commissions established pursuant to the Military Commissions Acts of 2006 and 2009;
namely, any person who was “part of forces associated with Al Qaeda or the Taliban,” along with
“those who purposefully and materially support such forces in hostilities against U.S. Coalition
partners.”18 While the panel concluded that either purposeful and material support for an AUMFtargeted organization in hostilities against the United States or membership in such an
17

A third member of the panel issued a separate opinion concurring with the majority’s judgment. However, the
opinion did not clearly endorse the majority’s view as to the scope of the Executive’s detention authority. See AlBihani v. Obama, 590 F.3d 866, 883-885 (D.C. Cir. 2010) (Williams, J., concurring) (arguing that petitioner was
detainable on account of being “part of” an AUMF-targeted organization, but not deciding whether a person could be
detained on account of “support” for a targeted organization that he was not also a “part of”).

organization may be independently sufficient to justify detention, the court declined “to explore
the outer bounds of what constitutes sufficient support or indicia of membership to meet the
detention standard.” It did, however, note that this standard would permit the detention of a
“civilian contractor” who “purposefully and materially supported” an AUMF-targeted
organization through “traditional food operations essential to a fighting force and the carrying of
arms.”19 Notwithstanding the government’s reliance on the law of war to interpret the scope of the
AUMF and arguably in conflict with Supreme Court discussion of the issue in Hamdi, the panel
rejected the idea that the international law of war has any relevance to the courts’ interpretation of
the scope of the detention power conferred by the AUMF.
The panel also held that the procedural protections afforded in habeas cases involving wartime
detainees do not need to mirror those provided to persons in the traditional criminal law context,
where evidence must demonstrate guilt beyond reasonable doubt, or the lesser procedures courts
have used in any specific habeas context. The panel stated:
[C]ourts are neither bound by the procedural limits created for other detention contexts nor
obliged to use them as baselines from which any departures must be justified. Detention of
aliens outside the sovereign territory of the United States during wartime is a different and
peculiar circumstance, and the appropriate habeas procedures cannot be conceived of as mere
extensions of an existing doctrine. Rather, those procedures are a whole new branch of the
tree.20

In the context of military detention of enemy belligerents, the court found, the government need
only support its authority to detain using a “preponderance of evidence” standard.21 The court
rejected the petitioner’s argument, based on his reading of Hamdi,22 that any relaxation of
procedural standards must be justified by the particular exigencies of the case. The court
established the hearsay rule for detainee habeas cases, at least those brought by aliens abroad23:
[T]he 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.24

The D.C. Circuit thereafter denied a petition for an en banc rehearing of the Al-Bihani case.
However, a concurring opinion joined by a majority of the active appellate court judges
characterized certain aspects of the panel’s decision, concerning the application of international
law of war principles in interpreting the AUMF, to be non-binding dicta.25 It did not address
19
Id. at 872-873. The panel found that even if petitioner was not a member of an AUMF-targeted organization, his

whether any portions of the Al-Bihani ruling concerning the lawfulness of detaining persons on
account of membership or support for Al Qaeda, the Taliban, or associated forces also constituted
non-binding dicta. However, circuit court decisions since Al-Bihani have appeared to construe the
AUMF as authorizing the Executive to detain persons who are “part of” organizations targeted by
the AUMF as well as those who provide support to such entities.26 Moreover, the 2012 NDAA
expressly authorizes the detention of persons who have “substantially supported al-Qaeda, the
Taliban, or associated forces that are engaged in hostilities against the United States or its
coalition partners, including any person who has … directly supported such hostilities in aid of
such enemy forces.”27
In any event, in litigation following Al-Bihani involving Guantanamo detainees, the Obama
Administration has not justified its detention claims solely on the grounds that a particular
detainee provided support to Al Qaeda or the Taliban. Instead, its legal justification for holding
persons on account of wartime activity has been that they were at least functionally “part of” Al
Qaeda, the Taliban, or an associated force at the time of capture.
The Supreme Court denied a petition to review the Al-Bihani decision. The case should not be
confused with a similarly named case involving the petitioner’s brother.28 The habeas petitioner in
that case also sought Supreme Court review of the denial of his habeas petition, but the Court
declined to hear the case.

Al-Adahi v. Obama, 613 F.3d 1102 (D.C. Cir. 2010), cert. denied,
131 S. Ct. 1001 (2011)
In Al-Adahi, a three-judge panel of the D.C. Circuit endorsed the use of “conditional probability
analysis” by habeas courts when considering the sufficiency and reliability of evidence proffered
by the government in support of its claim that a person is lawfully detained under the AUMF. The
case involved review of a district court decision granting a habeas petition by a Guantanamo
detainee who the government claimed was “part of” Al Qaeda, following its determination that
the government had failed to demonstrate its claim by a preponderance of evidence.
On appeal, the D.C. Circuit panel assumed arguendo that the government was required to show
by a preponderance of evidence that the petitioner was lawfully detained under the AUMF, but
suggested that reliance on this standard may not be constitutionally required. It next turned to the
district court’s analysis of evidence proffered by the government in support of its detention of
petitioner, and concluded that the lower court “clearly erred in its treatment of the evidence” and
its application of the preponderance of evidence standard. Examining the record, the circuit panel
held that the lower court erred by separately considering the sufficiency of each item of evidence
26

See, e.g., Almerfedi v. Obama, 654 F.3d 1, 4 n.2 (D.C. Cir. 2011) (“As we have explained [in Al-Bihani], the
government may detain any individual ‘engaged in hostilities ... against the United States,’ who ‘purposefully and
materially supported hostilities against the United States or its coalition partners,’ or who ‘is part of the Taliban, al
Qaeda, or associated forces.’”); Hatim v. Gates, 632 F.3d 720 (D.C. Cir. 2011) (per curiam panel decision) (finding that
district court ruling that military could only detain person who was “part of” Al Qaeda or the Taliban was “directly
contrary to Al-Bihani v. Obama, which held that ‘those who purposefully and materially support’ al-Qaida or the
Taliban could also be detained”).

proffered by the government, and finding that the government failed to meet its evidentiary
burden because no individual piece of evidence provided sufficient grounds to justify the
petitioner’s detention. The circuit panel was also critical of the lower court for failing to make any
findings regarding the petitioner’s “implausible” and inconsistent explanations for some of his
activities, stating that it is a “well-settled principle that false exculpatory statements are
evidence—often strong evidence—of guilt.”
According to the circuit panel, “conditional probability analysis” is appropriate for assessing
whether a person’s detention under the AUMF is supported by the preponderance of the evidence.
Using this framework, a habeas court must consider the cumulative weight and effect of proffered
evidence when assessing whether the government has satisfied its evidentiary burden. In
describing “conditional probability analysis” and its implications for the assessment of the
evidence in the case before it, the Al-Adahi panel wrote:
“Many mundane mistakes in reasoning can be traced to a shaky grasp of the notion of
conditional probability.” JOHN ALLEN PAULOS, INNUMERACY: MATHEMATICAL ILLITERACY
AND ITS CONSEQUENCES 63 (1988). The key consideration is that although some events are
independent (coin flips, for example), other events are dependent: “the occurrence of one of
them makes the occurrence of the other more or less likely.... ” JOHN ALLEN PAULOS,
BEYOND NUMERACY: RUMINATIONS OF A NUMBERS MAN 189 (1991). Dr. Paulos gives this
example: “the probability that a person chosen at random from the phone book is over 250
pounds is quite small. However, if it’s known that the person chosen is over six feet four
inches tall, then the conditional probability that he or she also weighs more than 250 pounds
is considerably higher.” INNUMERACY 63.
Those who do not take into account conditional probability are prone to making mistakes in
judging evidence. They may think that if a particular fact does not itself prove the ultimate
proposition (e.g., whether the detainee was part of al-Qaida), the fact may be tossed aside
and the next fact may be evaluated as if the first did not exist. This is precisely how the
district court proceeded in this case: Al-Adahi’s ties to bin Laden “cannot prove” he was part
of Al-Qaida and this evidence therefore “must not distract the Court.” … The fact that AlAdahi stayed in an al-Qaida guesthouse “is not in itself sufficient to justify detention.” AlAdahi’s attendance at an al-Qaida training camp “is not sufficient to carry the Government’s
burden of showing that he was a part” of al-Qaida. And so on. The government is right: the
district court wrongly “required each piece of the government’s evidence to bear weight
without regard to all (or indeed any) other evidence in the case. This was a fundamental
mistake that infected the court’s entire analysis.”29

Employing this standard, the circuit panel examined the evidentiary record (including false
exculpatory statements made by the petitioner during interrogation),30 and concluded that the
government had satisfied its evidentiary burden of proving that the petitioner was subject to
detention on account of membership in Al Qaeda. The circuit panel also concluded that some of
the individual pieces of evidence proffered by the government—including evidence showing that
the petitioner had voluntarily stayed at an Al Qaeda guesthouse and had received and executed

In support of its finding that the government had demonstrated by a preponderance of evidence that the petitioner
was a member of Al Qaeda, the circuit panel cited, inter alia, evidence relating to the petitioner’s travel to Afghanistan
in 2001, his subsequent meetings with Osama Bin Laden, his stay at an Al Qaeda guesthouse, his presence at an Al
Qaeda-affiliated training camp, and his wearing of a watch at the time of capture that was of the same model as that
used by Al Qaeda operatives.

orders from Al Qaeda members while at a weapons training camp—constituted sufficient grounds
to justify his detention.
The Supreme Court denied a petition of certiorari to review the Al-Adahi ruling.

Awad v. Obama, 608 F.3d 1 (D.C. Cir. 2010), cert. denied, 131 S. Ct. 1814 (2011)
This case involved the review of a district court’s denial of habeas relief to a Guantanamo
detainee whom the government alleged to have been “part of” Al Qaeda at the time of capture.
The petitioner, a Yemeni national, admitted to U.S. interrogators that he had travelled to
Afghanistan to receive weapons training and fight U.S. forces. He was subsequently injured in an
air raid, which resulted in the amputation of one of his legs. When Al Qaeda took over a portion
of a hospital where petitioner was being treated, he allegedly joined Al Qaeda fighters barricaded
there when coalition forces attempted to re-take the hospital, but he was surrendered by Al Qaeda
fighters due to his injury.
In upholding the district court’s denial of habeas relief, the circuit panel rejected several legal and
factual challenges raised by petitioner. As an initial matter, the Awad panel reaffirmed the
propriety of using conditional probability analysis, previously relied upon by the D.C. Circuit in
Al-Adahi, to assess petitioner’s evidentiary challenges; accordingly, it would not “weigh each
piece of evidence in isolation, but [would] consider all of the evidence taken as a whole.” The
circuit panel then proceeded to consider petitioner’s argument that some of the evidence that had
been proffered against him, including Al Qaeda documents and out-of-court statements by
another detainee who was present at the hospital where petitioner was apprehended, were
unreliable hearsay. The panel noted past jurisprudence recognizing that “hearsay evidence is
admissible in this type of habeas proceeding if the hearsay is reliable,” and concluded that the
proffered evidence was sufficiently reliable to have been considered by the lower court.
The court then turned to petitioner’s legal challenges. The panel rejected petitioner’s argument
that the government was required to justify its claims that he was lawfully detainable through
clear and convincing evidence, and found that the less rigorous “preponderance of evidence”
standard that had been relied upon by the district court was constitutionally permissible. The
circuit panel also dismissed petitioner’s argument that his habeas petition could only be denied if
a specific finding of fact was made that petitioner would pose a threat to the United States and its
allies if released. The panel characterized the circuit court’s prior decision in Al-Bihani as
foreclosing this argument, and it went on to state that
the United States’s authority to detain an enemy combatant is not dependent on whether an
individual would pose a threat … if released but rather upon the continuation of hostilities....
Whether a detainee would pose a threat to U.S. interests if released is not at issue in habeas
corpus proceedings in federal courts concerning aliens detained under the authority conferred
by the AUMF.

Finally, the panel rejected petitioner’s argument that, in order for the government to justify his
detention under the AUMF, it would have to demonstrate that he was part of Al Qaeda’s
“command structure.” The panel held that petitioner’s actions in joining Al Qaeda fighters behind
a barricade were sufficient grounds to conclude he was “part of” Al Qaeda. It also suggested other
situations where the government would not need to prove that a detainee was subject to Al
Qaeda’s “command structure” in order to justify its conclusion that he was “part of” Al Qaeda,

such as when a person was captured in Afghanistan as part of a group that was shooting at U.S.
forces and identified himself upon capture as an Al Qaeda member.
The Supreme Court denied a petition to review the Awad decision.

Al Odah v. United States, 611 F.3d 8 (D.C. Cir. 2010), cert. denied, 131 S. Ct. 1812
(2011)
In June 2010, a three-judge panel of the D.C. Circuit upheld a district court’s denial of a habeas
petition brought on behalf of a person who had been detained at Guantanamo since 2002 due to
his allegedly being part of Al Qaeda and Taliban forces. The petitioner challenged the procedures
used by the district court when admitting evidence, and also the sufficiency of the evidence upon
which its judgment on the merits was based. The circuit panel rejected these challenges as being
foreclosed by controlling legal precedent. Specifically, the panel rejected the petitioner’s
argument that the government was required to support its factual claims in support of the legality
of the petitioner’s detention through “clear and convincing evidence.” The panel recognized that
based on binding precedent within the circuit, it is “well-settled law that a preponderance of the
evidence standard is constitutional in considering a habeas petition from an individual detained
pursuant to authority granted by the AUMF.”31
The panel further rejected petitioner’s argument that the admission of hearsay was statutorily
restricted by the Federal Rules of Evidence and federal habeas statute. The court found this
argument unpersuasive, citing both to the Supreme Court’s ruling in Hamdi and the appellate
court’s prior jurisprudence as recognizing that district courts may admit reliable hearsay evidence
when considering a habeas petition by an individual detained under the AUMF. In this case, the
court agreed with the lower court that the hearsay evidence demonstrated sufficient indicia of
reliability to be accorded weight:
For example, in considering interrogation reports of a third party concerning al Qaeda and
Taliban travel routes into Afghanistan, the [district] court noted that this hearsay was
corroborated by “multiple other examples of individuals who used this route to travel to
Afghanistan for the purpose of jihad.” The court indicated that it was aware of the limitations
of this evidence when it concluded that “[although far from conclusive, the Government’s
evidence suggests that an individual using this travel route to reach Kandahar may have done
so because it was a route used by some individuals seeking to enter Afghanistan for the
purpose of jihad.”32

The court approved this analysis of hearsay and declined to find an abuse of discretion on the part
of the district court. The panel also rejected the petitioner’s challenges to the individual pieces of
evidence proffered by the government in support of his detention.
On April 4, 2011, the Supreme Court denied a petition to review the Al-Odah decision. The AlOdah ruling has been relied upon by the D.C. Circuit in other cases, including in one case in
which a petition for certiorari was denied by the Supreme Court.33

Bensayah v. Obama, 610 F.3d 718 (D.C. Cir. 2010)
This case involved the review of a district court denial of habeas relief to an Algerian citizen who
had been arrested by Bosnian authorities in 2001 and was subsequently transferred to U.S.
custody for detention at Guantanamo. The government claimed that although the petitioner had
not directly taken part in combat activities against the United States, he had intended to travel to
Afghanistan to fight U.S. forces and had facilitated the travel of others to do the same. The
executive branch initially argued that it had legal authority to hold the detainee, pursuant to the
authority vested by the AUMF and the President’s “inherent authority” as Commander-in-Chief,
on account of the detainee’s alleged membership in and support for Al Qaeda. In 2008, a federal
district court judge denied the detainee’s habeas petition.34 The court found that the government
had sufficient grounds to detain the petitioner for providing support to Al Qaeda, but declined to
decide whether there were also sufficient grounds to detain the petitioner for being “part of” the
organization.
On appeal, the Executive eschewed reliance on certain evidence that it earlier relied upon to
demonstrate that petitioner acted as a travel facilitator for Al Qaeda, and also modified its
argument in support of petitioner’s detention—abandoning its argument that the petitioner was
subject to detention on account of providing support to Al Qaeda, and instead arguing that he was
subject to detention on account of being “part of” the organization. The government also relied
solely on the authority granted by the AUMF to justify its detention authority, rather than any
independent authority deriving from the Commander-in-Chief Clause. The reviewing circuit
panel reversed and remanded the case back to the district court, finding that evidence relied upon
by the lower court to conclude that the petitioner had supported Al Qaeda was insufficient to
show that he was “part of” the organization.
Portions of the appellate panel’s opinion discussing the sufficiency and reliability of the evidence
proffered by the government were largely redacted. However, the published opinion provided
further clarification regarding the D.C. Circuit’s view of the detention authority conferred by the
AUMF. The Bensayah panel recognized that the D.C. Circuit had previously made clear that “the
AUMF authorizes the Executive to detain, at the least, any individual who is functionally part of
al Qaeda.” According to the panel, because Al Qaeda’s organizational structure is generally
unknown and thought to be amorphous, a determination as to whether an individual is “part of”
the organization “must be made on a case-by-case basis by using a functional rather than a formal
approach and by focusing upon the actions of the individual in relation to the organization.”
Although the panel concluded that evidence demonstrating that a person operated within Al
Qaeda’s command structure was sufficient to show that he was “part of” the organization, it
suggested that there “may be other indicia that a particular individual is sufficiently involved with
the organization to be deemed part of it.” Nonetheless, the panel indicated that the “purely
independent conduct of a freelancer” is not sufficient grounds to deem him to be functionally part
of Al Qaeda.

Salahi v. Obama, 625 F.3d 745 (D.C. Cir. 2010)
This case involved review of a district court order granting habeas relief to a Guantanamo
detainee captured in 2001 in Mauritania. Although the petitioner had not fought against the
United States, the government alleged that he was lawfully detained on the grounds that he was
“part of” Al Qaeda. Most of the evidence proffered by the government in support of its
allegations concerned activities by the petitioner which occurred years before the 9/11 attacks. In
habeas proceedings before the lower court, the government presented evidence that petitioner
swore an oath of loyalty to Al Qaeda in 1991 and provided support to the organization at various
points thereafter, including by recruiting members, hosting organization leaders, and providing
the organization with financial support. For his part, the petitioner claimed that he severed ties
with Al Qaeda in the early 1990s. The district court ruled that the government failed to satisfy its
evidentiary burden in proving that the petitioner was “part of” Al Qaeda at the time of capture,
and ordered the detainee to be released. In doing so, it rejected the government’s argument that
once the petitioner swore an oath of allegiance to Al Qaeda, he bore the burden of demonstrating
that he had later withdrawn from the organization.
On appeal, a three-judge panel vacated the lower court’s decision, finding that intervening case
law—namely, the circuit court’s opinions in the Al-Adahi, Awad, and Bensayah cases discussed
above—cast doubt on the lower court’s approach to determining whether petitioner was “part of”
Al Qaeda. In particular, the Salahi panel found that the lower court had improperly required the
government to prove that the petitioner had received and executed orders from Al Qaeda in order
to demonstrate his membership in the organization. Subsequent circuit jurisprudence established
that membership could be demonstrated not only from evidence that a person was part of Al
Qaeda’s “command structure,” but also from activities which revealed a person to be functionally
part of the organization. The panel recognized, however, that in cases like the one involving
petitioner, who had not engaged in combat activities against the United States, “the government’s
failure to prove that an individual was acting under orders from al-Qaida may be relevant to the
question of whether the individual was ‘part of’ the organization when captured.”35
Although the government requested that the Salahi panel direct the district court to deny the
habeas petition, it declined to do so, finding that it was appropriate to remand the case so the
lower court could conduct further proceedings consistent with circuit jurisprudence that
developed after its initial ruling. The panel found that because the lower court lacked guidance
from subsequent circuit jurisprudence, it had primarily looked for evidence as to whether
petitioner participated in Al Qaeda’s command structure, but “did not make definitive findings
regarding certain key facts necessary for us to determine as a matter of law whether Salahi was in
fact ‘part of’ al-Qaida when captured.”
In remanding the case to the lower court for further factual findings, the Salahi panel reiterated
the admonition made by the circuit court in Al-Adahi that courts considering habeas petitions by
Guantanamo detainees must consider the assorted evidence relating to the government’s claims
collectively rather than in isolation. While the panel stated that the lower court appeared to have
generally followed this approach, it suggested that its consideration of certain evidence “may
have been unduly atomized.” Notably, the panel suggested that when the lower court determined
that the petitioner’s limited relationships with Al Qaeda operatives might have been too
insubstantial to independently serve as a basis for deeming the petitioner “part of” Al Qaeda,

those connections made it more probable that the petitioner was a member of the organization and
were thus relevant to an assessment as to whether he had been lawfully detained. The panel also
suggested that examining the petitioner’s oath to Al Qaeda in isolation from his subsequent
“sporadic support” may have resulted in the lower court failing to consider the possibility that this
support demonstrated the petitioner’s continued adherence to his oath of loyalty.
In reaching its ruling, the appellate court did not squarely address the government’s argument that
the petitioner’s oath to Al Qaeda in the early 1990s established an evidentiary burden upon him to
demonstrate that he had subsequently withdrawn from the organization. The appellate court also
declined to consider the government’s argument that the district court had accorded insufficient
weight to certain inculpatory statements that were made by petitioner in interrogations subsequent
to a period of time when he had been, by the government’s admission, subject to mistreatment,
because the panel viewed this issue to be irrelevant to the legal questions addressed by its opinion
conditional probability analysis.

Uthman v. Obama, 637 F.3d 400 (D.C. Cir. 2011), cert. denied, 132 S. Ct. 2739
(2012)
In Uthman, a three-judge circuit panel reversed and remanded a district court decision that had
granted habeas relief to a Yemeni national who had been captured in Afghanistan and detained by
U.S. forces since December 2001. In prior cases, including the Bensayah and Salahi decisions
discussed supra, the D.C. Circuit had recognized that the determination of whether a person was
“part of” Al Qaeda was based on a functional, case-by-case assessment which focused on the
individual’s actions in relation to the organization. The Uthman decision provided further
clarification as to the kind of circumstantial evidence that could potentially provide sufficient
grounds to support the detention of a person under the AUMF.
The government made several claims regarding Uthman’s activities in relation to Al Qaeda—
including that he attended an Al Qaeda training camp, fought against the Northern Alliance in
Afghanistan, and served as a bodyguard to Osama Bin Laden—which were contested.
Nonetheless, the D.C. Circuit panel found that the following facts, which were either found by the
district court or which were uncontested by Uthman, were sufficient to demonstrate that Uthman
was “more likely than not” part of Al Qaeda and therefore subject to detention: (1) he was
captured in December of 2001 in the vicinity of Tora Bora, where Al Qaeda forces had gathered
to fight United States and its allies; (2) at the time of capture, Uthman was travelling with a small
group including two Al Qaeda members who were bodyguards for Osama Bin Laden and a
Taliban fighter; (3) he had previously studied at a religious school in Yemen which was known as
“a fruitful al Qaeda recruiting ground,” and which had also been attended by the Al Qaeda and
Taliban fighters with whom Uthman had been captured; (4) Uthman’s travel route to Afghanistan
resembled that commonly used by Al Qaeda recruits; (5) his explanation for how he raised funds
to travel to Afghanistan was not viewed as credible by the district court, and constituted a “false
exculpatory” statement lending credence to the government’s claims of wrongdoing; (6) Uthman
was seen at an Al Qaeda guesthouse; and (7) Uthman’s exculpatory explanation of his activities in
Pakistan and Afghanistan involved “many coincidences that are perhaps possible, but not likely.”
Although the panel recognized that at least some of these findings, when viewed in isolation,
would not necessarily be sufficient to find that Uthman was functionally part of Al Qaeda, it ruled
that when the evidence proffered by the government was considered in totality, “Uthman’s actions
and recurrent entanglement with al Qaeda show that he more likely than not was part of al
Qaeda.”

The Supreme Court declined to review the decision.

Al-Madhwani v. Obama, 642 F.3d 1071 (D.C. Cir. 2011), cert. denied, 132 S. Ct.
2739 (2012)
In Al-Madhwani, a three-judge appellate panel reviewed and affirmed a lower court dismissal of a
habeas petition by a Guantanamo detainee. Madhwani argued that the government provided
insufficient evidence to demonstrate that he was subject to detention under the AUMF, and also
alleged that the district court had improperly considered evidence outside the record and had
committed procedural errors. The petitioner also claimed that he had been tortured by U.S.
authorities prior to his transfer to Guantanamo, and argued that statements he made to military
authorities at Guantanamo were tainted by his earlier coercion.
In upholding the district court’s denial of habeas, the circuit panel found it unnecessary to reach
Madhwani’s challenge that certain evidence had been tainted by undue coercion, as there was
sufficient evidence untainted by these claims to support the district court’s decision. The panel
noted that the district court had considered 260 exhibits and held a four-day merits hearing during
which petitioner himself testified for over one day, and discounted “a substantial portion” of the
government’s evidence based on a finding that it was tainted by mistreatment suffered by
petitioner prior to his transfer to Guantanamo. The panel found the evidence considered by the
lower court, including incriminating testimony by Madhwani in testimony, provided sufficient
grounds to support the government’s determination that he was “part of” Al Qaeda. This evidence
included admissions by Madhwani of his stay at an Al Qaeda-affiliated guest house and military
training camp; his admission to carrying a rifle at the behest of camp superiors, his “suspicious”
travel after departing the camp with recruits and “implausible” explanation for his travel; and the
circumstances of his final capture in the company of at least one known Al Qaeda operative.
The panel also rejected several other legal and evidentiary arguments made by Madhwani,
including certain arguments that had been previously rejected by the D.C. Circuit, including his
claim that hearsay evidence could only be admitted in wartime detention cases if it fell within an
exception recognized under the Federal Rules of Evidence.
The Supreme Court declined to review the case.

Almerfedi v. Obama, 654 F.3d 1 (D.C. Cir. 2011), cert. denied, 132 S. Ct. 2739
(2012)
In Almerfedi, a three-judge panel of the D.C. Circuit considered the government’s appeal of a
district court ruling granting habeas relief to a Guantanamo detainee whom the government
claimed had acted as a facilitator for Al Qaeda. The government based its claim primarily upon
admissions made by habeas petitioner Almerfedi himself, as well as statements made by another
Guantanamo detainee. The district court concluded, however, that Almerfedi’s statements did not
demonstrate by a preponderance of the evidence that Almerfedi was “part of” Al Qaeda. It also
declined to consider the testimony of the fellow Guantanamo detainee, concluding that it was
unreliable. The circuit panel reversed and remanded with instructions to the lower court to deny
Almerfedi’s habeas petition.
The circuit court’s ruling did not clearly pronounce any new legal standards governing
consideration of detainees’ habeas claims (though the majority opinion reiterated the suggestion

Judicial Activity Concerning Enemy Combatant Detainees: Major Court Rulings

made in Al-Adahi that the government might be able to support the detention of a person using a
lower standard than one based on the preponderance of evidence).36 However, some have viewed
the decision as significant because the court implied that the government’s evidence was not as
compelling as evidence proffered in prior cases reviewed by the D.C. Circuit, and might signify
“the minimum amount of evidence” necessary to demonstrate under a preponderance of evidence
standard that an individual was lawfully detained.37
The government’s contention that Almerfedi served as a facilitator for Al Qaeda was based on
several factors. By Almerfedi’s own admission, he had travelled from Yemen to Pakistan in 2001,
where he stayed for more than two months at the headquarters of Jama’at Tablighi, an Islamic
missionary organization designated by U.S. intelligence as a Terrorist Support Entity closely
aligned with Al Qaeda. He subsequently travelled to Iran, where he admitted staying for over a
month before being arrested by Iranian authorities with at least $2,000 cash in his possession. The
government further claimed, based on statements Almerfedi allegedly made to another
Guantanamo detainee named al-Jadani, that while Almerfedi was in Iran he stayed at an Al Qaeda
guest house in Tehran. Al-Jadani also claimed that other, unnamed Guantanamo detainees had
informed him that a “Hussain al-Aden” acted as an Al Qaeda facilitator at the Tehran guesthouse,
and the government believed that “Hussain al-Adeni was the same person as Almerfedi because
the nisha ‘al-Adeni’ means ‘from Aden,’ which is [the Yemeni city] where Almerfedi is from.”38
For his part, Almerfedi denied that he had ever stayed at an Al Qaeda guesthouse or served as a
facilitator, and noted that the dates when al-Jadani claimed he stayed at the guesthouse were
obviously incorrect, because it was undisputed that Almerfedi had been arrested by Iranian
authorities at least a year earlier. Almerfedi alleged that he had left Yemen in order to seek a better
life in Europe. He claimed to have travelled to Pakistan because it would be easier to obtain a visa
there, and that he stayed with Jama’at Tablighi in the hope that he could take advantage of the
travel discounts they offered members (even though he denied ever being a member of the
organization). He further alleged that his subsequent travel to and stay in Iran were part of a failed
attempt to be smuggled into Europe.
Examining the record, the circuit court concluded that “the government’s evidence, combined
with Almerfedi’s incredible explanations” provided sufficient grounds to detain Almerfedi even
without consideration of al-Jadani’s statements. The court noted that Almerfedi’s stay at the
headquarters of Jama’at Tablighi was “probative, by itself it presumably would not be sufficient
to carry the government’s burden because there are surely some persons associated with Jama'at
Tablighi who are not affiliated with al-Qaeda.”39 However, when this fact was considered along
with Almerfedi’s travel route, which the court described as being “quite at odds with his professed
desire to travel to Europe,” in addition to the circumstances of Almerfedi’s capture with at least
$2,000 of unexplained cash in his possession, the government’s case that Almerfedi acted as an Al
Qaeda facilitator “was on firmer ground.” Further, the circuit panel found that although the lower
court had recognized Almerfedi’s explanation of his activities as “perplexing” and unconvincing,
it erred by failing to assess these “false exculpatory statements” as amounting to evidence in
favor of the government’s position, as the D.C. Circuit had held in Al-Adahi.

While finding that the admission of al-Jadani’s statements was unnecessary for the government to
satisfy the evidentiary burden justifying Almerfedi’s detention, two panel members nonetheless
concluded that the lower court clearly erred in ruling these statements as unreliable “jail house
gossip.” The district court had rejected al-Jadani’s statements at least in part because al-Jadani
alleged that Almerfedi told him that he was at an Al Qaeda guesthouse in 2002 or 2003, though
Almerfedi had already been taken into custody by that time. The majority of the circuit panel
believed, however, that al-Jadani’s “timing confusions were inconsequential,” because the correct
date of Almerfedi’s capture had been given in some reports of al-Jadani’s interrogations by U.S.
authorities, and al-Jadani’s reliability had been established via a classified government declaration
which buttressed many of his statements regarding Al Qaeda guesthouses in Iran. The majority of
the panel also believed that the district court erred when it failed to assess al-Jadani’s recounting
of conversations with unnamed detainees that implicated Almerfedi. The panel majority viewed it
as “quite understandable that al-Jadani would be reluctant” to identify these detainees to U.S.
authorities. Moreover, the panel majority found it significant that al-Jadani knew specific details
regarding the capture of a “Hussain al-Aden” by Iranian authorities and his subsequent transfer
first to Afghan and then to U.S. custody. The panel majority characterized the circumstances as
matching “Almerfedi’s unique experiences and therefore mak[ing] clear that Hussain Almerfedi
and Hussain al-Adeni are the same man,” buttressing the credibility of al-Jadani and that of the
unnamed detainees who purportedly identified Almerfedi as an Al Qaeda facilitator.
Writing separately, D.C. Circuit Judge Judith W. Rogers concurred with the panel majority in its
ruling that the government had satisfied the evidentiary burden needed to support Almerfedi’s
detention. However, Judge Rogers disagreed with the majority’s analysis of the recorded
statements of al-Jadani. The district court’s determination that al-Jadani’s statements were
unreliable was a factual one that could only be reversed for clear error, and an examination of the
record evidenced did “not lead to a ‘firm conviction’ that the district court’s analysis of alJadani’s statements was mistaken, much less implausible.”
The Supreme Court declined to review the circuit court’s decision.

Al Alwi v. Obama, 653 F.3d 11 (D.C. Cir. 2011), cert. denied, 132 S. Ct. 2739 (2012)
In this case, a circuit panel found that although the corroboration of hearsay statements has
proved useful to establish their reliability, corroboration of statements made by the petitioner
himself during interrogations is not necessary to find that he is lawfully detained. The district
court had sustained Al Alwi’s detention based on admissions he made during interrogation that
established he had traveled to Afghanistan to join the fight against the Northern Alliance, had
stayed in at least three guesthouses associated with enemy forces, received military training and
participated in hostilities against the Northern Alliance, and was part of a unit that was bombed
by U.S. forces in late 2001.40 Al Alwi sought to have the denial of his habeas petition reversed on
the basis that his statements were insufficiently corroborated by other evidence, which he argued
was required under the “corroboration rule” applicable in criminal trials. The appellate court
expressed skepticism that such a rule still exists in the criminal context, but regarded it as
irrelevant to habeas proceedings,41 where other indicia of reliability could satisfy the requirement
to assess the probative value of such statements. In this case, the interrogation reports were found

to be sufficiently reliable because Al Alwi’s statements were consistent and he did not contend
that he gave false answers during any specific session due to the coercive interrogation methods
he alleged were used. Moreover, the government did submit evidence other than the petitioner’s
statements to demonstrate the connection between the admissions and inferences that could be
drawn from them (i.e., such conduct was typical of Taliban and Al Qaeda recruits).42
The appellate court declined to review the petitioner’s argument that his detention was no longer
lawful because the “associated force” of which he was allegedly a member is no longer engaged
in hostilities, stating that he had failed to raise the argument before the lower court and that there
was sufficient evidence to establish he was a part of the Taliban or Al Qaeda.43 The court also
rejected Al Alwi’s argument that the government must prove not only that he was “part of” Al
Qaeda or the Taliban, but also that he “substantially supported” one of those entities. Although the
district court had not squarely addressed whether Al Alwi was a part of any group of combatants,
the appellate court found that enough facts had been established for it to make that determination
on review, without remanding the case for further finding of fact. Finally, the circuit panel
rejected the petitioner’s contention that the district court’s denial of his unopposed request for a
30-day continuance amounted to an abuse of discretion. He had asked for extra time because he
had been unable to meet with his attorneys due to his having begun a hunger strike, but the court
denied the request because Al Alwi was himself responsible for the delay. While the appellate
court agreed that the denial of Al Alwi’s request was difficult to understand in light of the fact that
the district court had granted the government a similar continuance without objection, it stated
that the petitioner must be able to demonstrate actual prejudice from the denial, which he had
failed to do. The district judge had permitted his attorneys to submit an amended response, and at
any rate, according to the panel, it could not be demonstrated that 30 days would have made an
appreciable difference given the amount of time his counsel had been working with him through
the CSRT and habeas proceedings.
The Supreme Court declined to accept an appeal of the case.

In this case a three-judge circuit panel reviewed a district court ruling granting the habeas petition

demonstrate its allegation that Latif, a Yemeni national who had travelled to Afghanistan and was
subsequently captured in Pakistan, had fought with the Taliban and was subject to detention. In a
2-1 decision, the panel vacated the district court’s ruling and remanded the case for further
proceedings.44 The panel’s published decision was initially heavily redacted, but much of the
discussion centered on classified government intelligence documents that served as the primary
evidentiary basis supporting the government’s allegations. The opinion was later reissued with
fewer redactions.45

Judicial Activity Concerning Enemy Combatant Detainees: Major Court Rulings

The panel majority found that the district court erred by not affording a “presumption of
regularity” to the intelligence documents proffered by the government, and that Latif had not
presented evidence to satisfactorily rebut the presumption that the intelligence documents
accurately recorded the statements made therein.
The controlling opinion in Latif, written by Judge Brown, described the presumption of regularity
as applicable to “the official acts of public officers and, in the absence of clear evidence to the
contrary, courts presume that they have properly discharged their official duties.” Judge Brown
distinguished a presumption of regularity from a presumption of truthfulness, and suggested that
confusion over the distinction might explain the prior reluctance of lower courts to accord a
presumption of regularity to government intelligence documents:
The confusion stems from the fact that intelligence reports involve two distinct actors—the
non-government source and the government official who summarizes (or transcribes) the
source’s statement. The presumption of regularity pertains only to the second: it presumes
the government official accurately identified the source and accurately summarized his
statement, but it implies nothing about the truth of the underlying non-government source’s
statement. There are many conceivable reasons why a government document might
accurately record a statement that is itself incredible. A source may be shown to have lied,
for example, or he may prove his statement was coerced. The presumption of regularity—to
the extent it is not rebutted—requires a court to treat the Government’s record as accurate; it
does not compel a determination that the record establishes what it is offered to prove.46

The majority characterized the application of a presumption of regularity to intelligence
documents as being supported by separation of powers principles; because “courts have no
special expertise in evaluating the nature and reliability of the executive branch’s wartime record
... it is appropriate to defer to executive branch expertise.”47 The majority also noted that this
presumption regularly given to government documents in other contexts, including in ordinary
criminal cases. It also discussed prior D.C. Circuit rulings which it characterized as being
consistent with or lending support to the panel’s holding.
Reviewing the evidence before the district court, the panel majority found that the intelligence
report proffered by the government, if reliable, provided sufficient evidence to demonstrate the
lawfulness of Latif’s detention. Because the majority held that this report was entitled to a
presumption of regularity, and because Latif “challenge[d] only the reliability of the Report,” the
majority found that it could only uphold the district court’s grant of habeas if Latif was able to
rebut the government’s evidence “with more convincing evidence of his own.”48 The majority
found that he had not done so, and in addition, it found that the district court had failed to
consider properly relevant evidence in assessing Latif’s credibility, including the similarity
between Latif’s travel route and that commonly used by Al Qaeda and Taliban fights, as well as
potentially incriminating statements that he made. The panel remanded the case back to the
district court for further consideration of the evidence.

Judge Henderson wrote a separate concurrence to the panel decision, agreeing with the
controlling opinion’s analysis but arguing that remand was unnecessary and that the panel should
have simply reversed the lower court’s grant of habeas.
Writing in dissent, Judge Tatel argued that the district court’s factual findings were subject to a
deferential clear error standard of review, and that employing this standard would have resulted in
affirming the lower court’s grant of habeas. He also disputed the majority’s holding that a
presumption of regularity should apply to government intelligence documents in habeas cases. He
characterized the presumption as typically being applied to those government documents which
are “familiar, transparent, generally understood as reliable, or accessible.” Judge Tatel argued that
presumption should not apply to intelligence documents of the kind at issue here, which “was
produced in the fog of war by a clandestine method that we know almost nothing about.” He
further expressed fear that application of this presumption would in practice come “perilously
close to suggesting that whatever the government says must be treated as true.... ”49
The Supreme Court denied certiorari to review the Latif decision.50

Al Warafi v. Obama, 716 F.3d 627 (D.C. Cir. 2013)
Mukhtar Al Warafi denied that he was part of the Taliban, and argued that even if he were a part
of the organization, he was not lawfully subject to detention because he served “permanently and
exclusively as ‘medical personnel’” within the meaning of the Geneva Conventions and their U.S.
Army implementing regulations, AR 190-8.51 Article 24 of the First Geneva Convention52
provides protections to full-time medical personnel, and Article 28 directs that they “shall be
retained only insofar as the state of health, the spiritual needs and the number of prisoners of war
require.” The Army Regulation implements the Geneva Conventions provisions concerning the
detention of “retained personnel,” including medical personnel. Although Congress included a
provision in Section 5 of the Military Commissions Act of 200653 stating that detainees may not
invoke the Geneva Conventions in a habeas proceeding, the three-judge panel found the detainee
may nevertheless invoke the Army Regulation implementing them. However, the district court
found the detainee had failed to prove his status as a medic, inasmuch as he lacked the
identification card and armlet bearing the distinctive emblem required elsewhere under the First
Geneva Convention for medical personnel.54 The petitioner argued that it should remain open to
him to prove his status by other means, but the circuit court agreed with the court below that
because the Taliban failed to provide medical personnel the required means of identification, such
personnel are not entitled to the special protections described in Article 24. Al Warafi’s detention
was affirmed.

Hussain v. Obama, 718 F.3d 964 (D.C. Cir. 2013), cert. denied, 134 S. Ct. 1621
(2014)
The petitioner in this case was a teenager when he was captured in Pakistan after spending time
with Taliban soldiers near the front in Afghanistan as well as in a series of mosques run by an
organization associated with Al Qaeda. He argues that he never took part in hostilities and was
never part of the command structure of the Taliban or Al Qaeda. The district court found that he
was nevertheless part of the Taliban or Al Qaeda.55 He appealed. The D.C. Circuit affirmed, with
two of the judges invoking at one point the “walks like a duck test” to approve the lower court’s
reasoning.56 They found the undisputed facts of the case coupled with the petitioner’s
unpersuasive explanations for them to support a finding that the petitioner was more likely than
not a member of the Taliban or Al Qaeda, making his detention lawful under the AUMF.
Senior Circuit Judge Edwards wrote a concurring opinion conceding that the evidence was
sufficient under circuit precedent to support detention. He objected, however, that the evidence
adduced did not in his view meet the preponderance of the evidence standard the court has said it
employs. He would have required the government to provide positive evidence that Hussain fit
within the AUMF standard at the time of his capture.
The Supreme Court declined to review the decision. Justice Breyer concurred in the denial of
certiorari, but indicated his vote might have been different had the petitioner asked for review on
the claim that he was not an “individual who ... was part of or supporting forces hostile to the
United States or coalition partners in Afghanistan and who engaged in an armed conflict against
the United States there” pursuant to the Hamdi case.57 Another detainee case, Ali v. Obama,58 has
responded to the invitation to bring this question before the Supreme Court.

Transfer and Release of Detainees
The D.C. Circuit has also considered a number of cases involving issues related to the transfer or
release of Guantanamo detainees. Some of these cases concern the remedy available to persons
whom a reviewing court has determined to be unlawfully held, but who cannot be resettled or
repatriated to a foreign country in the near future due to legal or practical obstacles.59 Other cases
involve challenges by detainees to their impending transfer to a specific foreign country, where
detainees claim that they would be tortured or unlawfully detained by the government of the
receiving country. The D.C. Circuit has also indicated that it is highly unlikely that a detainee
may challenge his designation as an enemy combatant after being released from U.S. custody and
transferred to a foreign country.

Kiyemba v. Obama, 555 F.3d 1022 (D.C. Cir. 2009) (“Kiyemba I”), vacated,
559 U.S. 131 (2010), reinstated as amended, 605 F.3d 1046 (D.C. Cir. 2010)
(“Kiyemba III”), cert. denied, 131 S. Ct. 1631 (2011)
In October 2008, a federal district court ordered the release into the United States of several
Guantanamo detainees who were no longer considered enemy combatants but who could not be
returned to their home country (China) because of the likelihood they would be subjected to
torture there, finding that the political branches’ plenary authority in the immigration context did
not contravene the petitioners’ entitlement to an effective remedy to their unauthorized
detention.60 However, the D.C. Circuit panel stayed the district court’s order pending appellate
review,61 and subsequently reversed the district court’s decision in the case of Kiyemba v. Obama
(“Kiyemba I”), decided in February 2009. The majority held that although the constitutional writ
of habeas enables Guantanamo detainees to challenge the legality of their detention, habeas courts
lack authority (absent the enactment of an authorizing statute) to compel the transfer of a noncitizen detainee into the United States, even if that detainee is found to be unlawfully held and the
government has been unable to effectuate his release to a foreign county. The Kiyemba I panel’s
decision was primarily based on long-standing jurisprudence in the immigration context which
recognizes that the political branches have plenary authority over whether arriving aliens may
enter the United States. The majority of the panel also found that Guantanamo detainees were not
protected by the Due Process Clause of the Constitution, as they are non-citizens held outside the
U.S. and lack significant ties to the country.
As discussed supra, the Supreme Court granted certiorari to review the Kiyemba ruling, and
subsequently vacated the appellate court’s opinion and remanded the case in light of the fact that
several countries had thereafter agreed to resettle the petitioners. In May 2010, the D.C. Circuit
panel reinstated its earlier opinion, as modified to take into account subsequent congressional
enactments limiting the use of funds to release any Guantanamo detainee into the United States
(the panel’s reinstatement is commonly referred to as “Kiyemba III,” to distinguish it from the
Circuit panel’s initial ruling and an intervening case also entitled Kiyemba v. Obama). The
Supreme Court declined to review Kiyemba III.

Kiyemba v. Obama, 561 F.3d 509 (D.C. Cir. 2009) (“Kiyemba II”), cert. denied,

In another case entitled Kiyemba v. Obama (commonly referred to as “Kiyemba II”), a D.C.
Circuit panel considered habeas petitions by detainees who were no longer considered enemy
combatants, and who sought to prevent their transfer to any country where they would likely face
further detention or torture. The Kiyemba II panel rejected the government’s argument that the
MCA stripped the court of jurisdiction to hear claims related to the petitioners’ proposed transfer.
The panel interpreted Boumediene as invalidating the MCA’s court-stripping provisions with
respect “to all habeas claims brought by Guantanamo detainees, not simply with respect to socalled ‘core’ habeas claims” relating to the legality of the petitioners’ detention. However, the
panel held that an executive branch determination that a detainee will not be tortured if
transferred to a particular country is binding on the court, and a habeas court may not secondguess this assessment. The circuit panel also reversed a district court ruling that required the

government to provide 30 days’ notice to detainees’ counsel before any proposed transfer. As a
result of this ruling, the detainees’ ability to challenge their proposed transfer from Guantanamo
may be quite limited. On March 22, 2010, the Supreme Court denied a petition for writ of
certiorari to review the appellate court’s ruling.
The Kiyemba II decision has been relied upon by the D.C. Circuit in subsequent rulings
concerning detainees’ right to challenge the Executive’s determination that they would not face
torture if transferred to a particular country and receive advance notice of their proposed transfer.

Gul v. Obama, 652 F.3d 12 (D.C. Circ. 2011), cert. denied, 132 S. Ct. 1906 (2012)
This case involved two former Guantanamo detainees who sought to challenge their designation
as “enemy combatants” by the U.S. government, despite the fact that they were no longer in U.S.
custody. Following the detainees’ transfer to foreign government custody, the lower court
dismissed their habeas petitions as moot. The detainees appealed to the D.C. Circuit, arguing that
dismissal was improper and that they had suffered collateral consequences even after leaving U.S.
custody because of their enemy combatant designation.
The three-judge panel upheld the lower court’s dismissal. The court held that even assuming that
courts may retain habeas jurisdiction over former detainees who suffer collateral consequences as
a result of their detention, the consequences identified by the petitioners did not constitute the
kind of injuries sufficient to give the court jurisdiction. Although petitioners claimed that their
designation as enemy combatants caused the countries to which they were transferred to restrict
their travel, the Gul panel did not find this to be an injury redressible by the court, because the
restrictions were imposed by the foreign governments rather than the United States. The panel
also was not persuaded by petitioners’ claim that they suffered a cognizable injury because their
“enemy combatants” designation barred their travel to the United States. As an initial matter, the
panel noted that there was no evidence that petitioners actually wanted to enter the United States.
Moreover, the court ruled that even the plaintiffs’ designation as enemy combatants was
rescinded, this would not remove the barriers to U.S. travel; by statute, all Guantanamo detainees
were placed on the government’s “no fly” list, regardless of enemy combatant status, and U.S.
immigration law’s restrictions on the admission of aliens posing security risks was not dependent
upon an enemy combatant designation. The panel also deemed petitioners’ claim that their
designation meant that they remained subject to possible targeting by the United States as “the
most speculative [claim] of all,” as the petitioners had “no basis whatsoever for believing” the
government might still pursue them after releasing them from custody. Finally, the court found
that binding precedent foreclosed consideration of petitioners’ argument that they suffered a
cognizable injury on the basis of the stigma caused by their designation.
The Supreme Court declined to review the case.

Other Notable Rulings
Besides the rulings discussed above, the appellate court for the D.C. Circuit has also issued
opinions on several other distinct issues related to U.S. detention policy. These rulings have
involved issues including, inter alia, the continuing application of the judicial review procedures
established under DTA following the Supreme Court’s ruling in Boumediene v. Bush; the ability
of former Guantanamo detainees to bring civil suit against U.S. officials based on the detainees’
allegedly wrongful treatment while in U.S. custody; the application of the constitutional writ of

habeas to persons held by the United States in foreign locations other than Guantanamo; and the
ability of detainees to seek redress for what they view as wrongful conditions of confinement.

Parhat v. Gates, 532 F.3d 834 (D.C. Cir. 2008)
In June 2008, a three-judge panel of the D.C. Circuit ruled in the case of Parhat v. Gates that the
petitioner had been improperly deemed an “enemy combatant” by a Combatant Status Review
Tribunal (CSRT), the first ruling of its kind by a federal court. The ruling, which occurred prior to
the Supreme Court’s decision in Boumediene, was made under the judicial review process that
had been established by the DTA. Although the D.C. Circuit has since held that the DTA review
process is no longer in effect, the Parhat decision continues to be cited within the D.C. Circuit for
its holding that evidence presented by the government must be in a form that permits a reviewing
court to assess its reliability.62
The petitioner in Parhat, an ethnic Chinese Uighur captured in Pakistan in December 2001, was
found by a CSRT to be subject to detention on account of his affiliation with a Uighur
independence group known as the East Turkistan Islamic Movement (ETIM), which was
purportedly “associated” with Al Qaeda and the Taliban and engaged in hostilities against the
United States and its coalition partners (the petitioner denied membership in the ETIM). The
Parhat panel found that the evidence presented by the government to support its claims regarding
the ETIM was insufficient to support the CSRT’s determination that Parhat was an enemy
combatant. Most significantly, the court found that the principal evidence presented by the
government regarding the ETIM being associated with Al Qaeda and the Taliban and engaged in
hostilities against the United States and its coalition allies—four government intelligence
documents describing ETIM activities and the group’s relationship with Al Qaeda and the
Taliban—did not “provide any of the underlying reporting upon which the documents’ bottomline assertions are founded, nor any assessment of the reliability of that reporting.”63 As a result,
the court found that neither the CSRT nor the reviewing court itself were capable of assessing the
reliability of the assertions made by the documents. Accordingly “those bare assertions cannot
sustain the determination that Parhat is an enemy combatant,”64 and the CSRT’s designation was
therefore improper. The circuit court stressed that it was not suggesting that hearsay evidence
could never reliably be used to determine whether a person was an enemy combatant, or that the
government must always submit the basis for its factual assertions to enable an assessment of its
claims. However, evidence “must be presented in a form, or with sufficient additional
information, that permits the [CSRT] and court to assess its reliability.”65
The Parhat panel also denied without prejudice a government motion to protect from public
disclosure any nonclassified information raised in the litigation that the executive branch had
62
Indeed, the D.C. Circuit in Bismullah implied that, despite its determination that the DTA review process was no
longer available to detainees, the circuit court’s ruling in Parhat remained in force. Bismullah, 551 F.3d 1068, 1075, n.
2 (D.C. Cir. 2009). See also Bensayah v. Obama, 610 F.3d 718, 725-726 (D.C. Cir. 2010) (“In Parhat we made clear

considering ‘sufficient additional information … permit[ting the fact finder] to assess its reliability.’”); Ameziane v.

labeled “law enforcement sensitive,” along with names and identifying information of U.S.
personnel mentioned in the record. While the panel acknowledged that information falling under
both of these categories warranted protection from public disclosure, it characterized the
government’s argument for nondisclosure as being supported only upon “a generic explanation of
the need for protection, providing no rationale specific to the information actually at issue in this
case.” In particular, the panel faulted the government motion for failing either to “give the court a
basis for withholding” a specific category of information, or a basis upon which the court could
“determine whether the information it has designated properly falls within the categories it has
described.”66

Bismullah v. Gates, 551 F.3d 1068 (D.C. Cir. 2009)67
This case concerned the continuing availability of DTA review procedures in light of the Supreme
Court’s ruling in Boumediene v. Bush that the constitutional privilege of habeas corpus extends to
non-citizen detainees held at Guantanamo. As discussed supra, following the Supreme Court’s
ruling in Gates v. Bismullah, the D.C. Circuit reinstated two earlier rulings concerning the scope
of judicial review of CSRT determinations available under the DTA. The government
subsequently petitioned for a rehearing of the case, arguing that the Supreme Court’s ruling in
Boumediene effectively nullified the review system established by the DTA, as Congress had not
intended for detainees to have two judicial forums in which to challenge their detention. The D.C.
Circuit granted the government’s motion for rehearing, and in Bismullah v. Gates, a three-judge
panel held that, in light of the Supreme Court’s ruling in Boumediene restoring detainees’ ability
to seek habeas review of the legality of their detention, the appellate court no longer had
jurisdiction over petitions for review filed pursuant to the DTA.

Rasul v. Myers, 563 F.3d 527 (D.C. Cir. 2009) (per curiam), cert. denied,
558 U.S. 1091 (2009)
Four British nationals formerly detained at Guantanamo sued the Secretary of Defense and
various military officers for damages, alleging that their treatment while in U.S. military custody
violated their rights under the Fifth and Eighth Amendments to the Constitution, the Geneva
Conventions, and other provisions of law. The district court dismissed the Bivens68 claims on the
basis of qualified immunity, holding that the officers could not reasonably be expected to have
anticipated that the plaintiffs, as aliens held overseas, would be entitled to rights under the U.S.
Constitution.69 The D.C. Circuit twice affirmed,70 interpreting Boumediene (on remand) as

Id. at 852-53. In Ameziane v. Obama, 620 F.3d 1 (D.C. Cir. 2010), the D.C. Circuit clarified that the government
need not provide a particularized explanation of the need to keep information protected with respect to a detainee, but
may provide a more generalized rationale with respect to a particular type of information and then demonstrate that the
information a detainee seeks to have released falls into that category.

“disclaim[ing] any intention to disturb existing law governing the extraterritorial reach of any
constitutional provisions, other than the Suspension Clause,”71 which, in the circuit court’s view,
appears to mean that those detained at Guantanamo have no rights under the Constitution (other
than the right to petition for habeas corpus). It rested its holding, however, on its analysis of
qualified immunity under Bivens, agreeing with the lower court that even if the Constitution does
provide some protections to the plaintiffs, the defendants were protected by qualified immunity.
Even were this not so clear, the D.C. Circuit noted a “special factor” precludes extending a Bivens
remedy to plaintiffs; namely, the “[t]he danger of obstructing U.S. national security policy.”72
Having found that the claims for damages were barred by the Federal Tort Claims Act, the circuit
court did not address whether Boumediene’s holding invalidating Section 7 of the MCA
encompassed only the portion of the provision that stripped courts of jurisdiction over habeas
claims, or whether the language eliminating other causes of action against the government had
also been invalidated.73 Subsequently in Al-Zahrani v. Rodriguez, discussed infra, the D.C.
Circuit held that the language in the MCA eliminating causes of action other than habeas corpus
survived Boumediene. 74 The D.C. Circuit later extended the holding to preclude lawsuits by
former detainees for their treatment after they had been declared to no longer be enemy
combatants.75

transferred to Bagram for long-term detention as enemy combatants. The district court held that
