Hamdan v. Rumsfeld, 548 U.S. 557 (2006), represents a landmark decision by the United States Supreme Court in which the justices determined that the military commissions set up by the Bush administration to prosecute detainees at Guantanamo Bay were inconsistent with both the Uniform Code of Military Justice (UCMJ) and the Geneva Conventions ratified by the United States.

The case of Hamdan tackled crucial legal questions, including whether Congress has the authority to prevent the Supreme Court from reviewing cases involving alleged enemy combatants before military tribunals; whether the executive branch’s specially created military commissions contravened federal statutes such as the UCMJ and international treaty obligations; and whether courts possess the power to enforce provisions of the Geneva Conventions.

Following oral arguments on March 28, 2006, the Court issued a 5–3 ruling on June 29, 2006, affirming its jurisdiction over the matter. It held that the administration lacked constitutional or legislative authorization to establish these commissions and ruled that without such authorization, these tribunals must adhere to U.S. law and international laws of war, including compliance with both the UCMJ and Geneva Conventions. Consequently, Hamdan’s trial under these commissions was declared unlawful.

Background

The petitioner, Salim Ahmed Hamdan, a Yemeni citizen, served as a driver and bodyguard for Osama bin Laden. Prior to this role, he participated in an agricultural initiative in Afghanistan sponsored by Bin Laden. Captured during the 2001 invasion, Hamdan was taken into American custody and transferred to the Guantanamo Bay detention camp in 2002.

In July 2004, Hamdan faced charges accusing him of conspiracy related to terrorism. The Bush administration arranged for his prosecution before a military commission established under Military Commission Order No. 1 dated March 21, 2002. His defense was led by Navy JAG officer LCDR Charles D. Swift, who filed a habeas corpus petition contesting the legality of the military commission on grounds that it failed to provide protections mandated by both the Geneva Conventions and the Uniform Code of Military Justice.

After the Supreme Court’s decision in Hamdi v. Rumsfeld (2004) affirmed detainees’ rights to habeas corpus review, Hamdan underwent a Combatant Status Review Tribunal, which confirmed his classification as an enemy combatant eligible for detention.

The defendants comprised several U.S. officials overseeing Hamdan’s detention; however, only then-Secretary of Defense Donald Rumsfeld is named in the case title as lead defendant.

District and Appeals Court rulings

Judge James Robertson of the United States District Court for the District of Columbia ruled in favor of Hamdan, concluding that military commissions could not proceed without first establishing that Hamdan was not entitled to prisoner-of-war status.

On July 15, 2005, a panel of three judges from the United States Court of Appeals for the District of Columbia Circuit, consisting of A. Raymond Randolph, John Roberts, and Stephen F. Williams, unanimously overturned this ruling. In his opinion, Judge Randolph supported the legality of military commissions based on several points:

Congressional authorization legitimized military commissions as appropriate venues for trying enemy combatants.
The Geneva Convention functions as an international treaty but does not confer enforceable individual rights within U.S. courts.
Even if enforceable, provisions of the Convention did not assist Hamdan because conflicts involving al-Qaeda are considered non-international and require only a "competent tribunal" without specific jurisdictional constraints.
Members of al-Qaeda are excluded from protections under the Geneva Convention.
Statutory law enacted by Congress authorized such judicial procedures.
The judiciary lacks jurisdiction to enforce Geneva Convention provisions, thereby invalidating Hamdan’s argument that trial must be postponed until prisoner-of-war status is determined.

Supreme Court ruling

On November 7, 2005, the Supreme Court agreed to review the case by granting certiorari. The petition was submitted on Hamdan's behalf by Neal Katyal from Georgetown University Law Center and Lieutenant Commander Charles Swift of the U.S. Navy, with additional legal support provided by the Seattle-based firm Perkins Coie.

Arguments were presented on March 28, 2006, with Katyal advocating for Hamdan and Paul Clement, the U.S. Solicitor General, representing the government. Chief Justice Roberts recused himself due to his prior involvement in the matter. Despite calls from some critics for Justice Scalia to recuse himself because of comments made before the hearing, he chose to remain on the panel.

On June 29, 2006, the Supreme Court overturned the decision of the Court of Appeals, ruling that President George W. Bush did not possess the authority to establish the war crimes tribunals and declaring these military commissions unlawful under both military justice statutes and the Geneva Conventions.

Stevens' majority opinion

Associate Justice John Paul Stevens authored the Court’s opinion, which secured a partial majority.

Initially, the opinion dismissed the government’s request to reject the case based on jurisdictional claims under the Detainee Treatment Act of 2005 (DTA), pointing out that Congress had not barred Supreme Court review. The Court distinguished this situation from Schlesinger v. Councilman by noting that Hamdan was not a service member subject to a court-martial but was instead facing a military commission. It referenced Ex parte Quirin to confirm its obligation to examine such cases.

On substantive grounds, Stevens refrained from determining whether the President held constitutional authority to convene military commissions but ruled that any such tribunals must adhere to war laws codified in Article 21 of the Uniform Code of Military Justice (UCMJ) or be explicitly authorized by legislation. The Authorization for Use of Military Force (AUMF) did not grant presidential powers beyond these restrictions.

Regarding compliance with laws of war, Stevens concluded that both the UCMJ and Geneva Conventions demand more extensive protections than those offered by these commissions. Significant violations identified included:

Limitations barring defendants and their counsel from accessing or discussing certain evidence;
Acceptance of any evidence with probative value, including hearsay and statements obtained through torture;
Appeals conducted exclusively within the Executive Branch rather than through judicial courts.

These procedural irregularities contravened provisions of the UCMJ.

The Court further determined that Common Article 3 of the Geneva Conventions applied and had been misapplied by the D.C. Circuit. The lower court erred by relying on Johnson v. Eisentrager and wrongly restricting protections to combatants present "in the territory" of a signatory nation. The Geneva Conventions require trials to be held by "regularly constituted courts," a standard these military commissions failed to meet.

Because these commissions violate both UCMJ requirements and Geneva Convention mandates, they lack lawful authority to try Hamdan.

The Court did not rule on whether Hamdan was entitled to a hearing under Geneva Convention Article 5 instead of a Combatant Status Review Tribunal, leaving that issue for future determination.

Sections lacking majority backing

Justice Anthony Kennedy refrained from joining several segments of Stevens' opinion, invoking judicial restraint—since the Court had already determined the military commissions were fundamentally flawed, further detailed examination was unnecessary. Consequently, these portions did not achieve majority endorsement.

One such segment presented Stevens' view that military commissions do not possess broad jurisdiction and are limited to prosecuting offenses explicitly recognized as war crimes by statute or judicial precedent (see Quirin). He found no statutory or case law support permitting conspiracy charges to be tried under law-of-war military commissions, referencing the Geneva Conventions, earlier Hague Conventions, and the Nuremberg Trials as authoritative frameworks.

Responses to dissenting opinions

Stevens’ opinion addressed principal dissenting points:

It pointed out that Justice Scalia’s argument about jurisdiction-stripping statutes overlooked the significance of the statute’s effective date clause.
It underscored that the government’s assertion of war commencement on September 11, 2001, contradicted Justice Thomas’ assertion of a 1996 start date.
It revealed that statements cited by Scalia from the Congressional Record were introduced after enactment by Senators Lindsey Graham and Jon Kyl, incorporating misrepresented quotations.

Breyer’s concurrence

Justice Breyer issued a concise concurrence, supported by Justices Kennedy, Souter, and Ginsburg, emphasizing that military commissions are permissible when expressly authorized by Congress:

Kennedy’s concurrence

Justice Kennedy authored a partial concurrence, with Justices Souter, Ginsburg, and Breyer joining parts I and II.

In the initial section, Kennedy raises concerns about separation of powers, stressing that vesting one branch with control over all aspects of a case—including trial, review, and appeal—poses constitutional challenges.

The second section contrasts military commissions with procedures under the Uniform Code of Military Justice (UCMJ), noting differences such as fewer jurors and modified evidentiary standards. These distinctions compromise impartiality and fairness protections, meaning the commissions do not qualify as "regularly constituted courts" under the Geneva Convention. Kennedy concludes that the commissions exceed congressional authorization but acknowledges that Congress could amend the legislation.

Kennedy’s final section outlines his hesitations: he does not require defendants’ presence at every trial stage, urges prudence in applying Article 75 of Protocol I (which the United States has not ratified), declines to rule on the validity of conspiracy charges, and refrains from evaluating other commission constraints discussed elsewhere in the ruling.

Scalia’s dissent

Justice Scalia wrote a dissent, joined by Justices Thomas and Alito, concentrating on jurisdictional matters.

He asserts that the Court erred in exercising jurisdiction over this case due to the Detainee Treatment Act (DTA) provision barring habeas corpus petitions by Guantanamo detainees. Scalia views this statute as sufficient to preclude Supreme Court jurisdiction and criticizes the majority’s interpretation of §1005(h) as unclear and inconsistent with precedent requiring explicit statutory language to remove jurisdiction in ongoing cases. He dismisses reliance on post-enactment Senate floor remarks and accuses the majority of disregarding the President’s signing statement.

Scalia warns that extending habeas corpus jurisdiction to Guantanamo detainees would overwhelm judicial resources. He maintains that the adequacy of the original military tribunal remains unchallenged and cites Johnson v. Eisentrager regarding Suspension Clause applicability.

He further contends detainees held outside U.S. sovereign territory lack habeas rights, referencing Hamdi v. Rumsfeld to highlight Hamdan’s indefinite detention following a Combatant Status Review Tribunal (CSRT).

Finally, Scalia criticizes the Court for prematurely invoking equitable jurisdiction, drawing an analogy to Schlesinger v. Councilman, where judicial intervention was deferred until completion of military court-martial proceedings; similarly, he argues military commissions should be allowed to conclude before courts intervene.

Thomas's dissent

Justice Clarence Thomas delivered his dissent directly from the bench, marking his first oral dissent since Stenberg v. Carhart (2000). He contended that the courts lacked proper jurisdiction, aligning with Justice Scalia’s dissenting view, and argued that Hamdan, classified as an illegal combatant, was not entitled to protections under the Geneva convention. Thomas maintained that the Geneva Convention does not forbid the establishment of the proposed special court-martial and that the President already possessed the authority to create such a tribunal.

Drawing upon his dissent in Hamdi v. Rumsfeld, Thomas underscored the constitutional separation of powers among the three branches during periods of war. He asserted that, according to precedents like Ex parte Quirin and Youngstown Sheet & Tube Co. v. Sawyer, President Bush’s choice to try Hamdan before a military commission deserved considerable judicial deference, particularly given Congress’s authorization of military force against terrorists through the Authorization for Use of Military Force.

Thomas strongly criticized the plurality’s skepticism regarding Hamdan’s charges, dismissing their questioning of Executive decisions as "unsupported assertions" and an unprecedented overreach into executive authority by the judiciary. He challenged their assumption that hostilities commenced only with the passage of the AUMF, proposing instead that Osama bin Laden’s 1996 jihad declaration might signify the conflict’s onset. Under this perspective, the AUMF authorized ongoing military actions rather than initiating them. Thomas also emphasized that military tribunals have historically exercised flexible jurisdiction under common law and faulted the plurality for insufficiently deferring to military expertise.

Referencing the Court’s recent ruling in Rapanos v. United States, Thomas highlighted a contrast between their reluctance to defer to wartime executive decisions and their readiness to uphold minor regulatory rulings, thereby stressing the heightened importance of deference in this context.

Thomas rejected the plurality’s conclusion that military commissions lack jurisdiction due to noncompliance with the UCMJ and Geneva Conventions. He argued that military commission authority adapts to circumstances and disputed any claim that Article 36 of the UCMJ restricts Executive power—contrary to established precedent. Regarding Geneva Convention arguments, Thomas cited Johnson v. Eisentrager to assert detainees cannot claim immunity from prosecution for war crimes. Even if Common Article 3 were applicable, he noted the Department of Justice’s stance that it does not extend protections to al Qaeda detainees, emphasizing respect for the President’s interpretation as Commander-in-Chief.

Alito's dissent

Justice Alito authored a seven-page dissent concurring with Justices Thomas and Scalia in asserting that courts lacked jurisdiction over this matter. He defended the legality of the military commission and disputed the Court’s conclusion that these commissions failed to qualify as "a regularly constituted court" under Common Article 3 of the Geneva Conventions. Alito argued that Common Article 3 requirements were met because these commissions:

function as courts,
were established pursuant to domestic law,
and procedural concerns can be addressed individually during review.

He dismissed claims labeling the commissions illegal due to alleged violations of , asserting they were indeed "regularly" constituted bodies. Alito drew parallels between these commissions and various local, state, federal, and international courts, which differ in structure yet remain regularly constituted.

Alito contended that Common Article 3 does not explicitly exclude military commissions and referred to Article 66 commentary cited by the Court. Even assuming Common Article 3 prohibits "special tribunals," he maintained this restriction does not apply here because these commissions are "regular." Using dictionary distinctions, he differentiated "special" as referring to a singular or exceptional entity from "regular," meaning consistent or uniform in operation. Given the Bush Administration’s intent to establish hundreds of such tribunals under standardized procedures, Alito concluded these commissions qualify as regular rather than special.

He noted that these commissions were created by presidential order, similar to those upheld in Ex parte Quirin (1942), which affirmed presidential authority to convene military commissions under predecessor statutes to . Alito opposed Justice Kennedy’s assertion that commissions must be independent from Executive influence to be "regularly constituted," arguing this criterion pertains more to fairness than regularity and pointing out that the commission in Quirin was comparable.

Addressing procedural rules criticized by the Court—such as allowing the Secretary of Defense to modify rules mid-trial and permitting evidence based on its "probative value to a reasonable person"—Alito argued neither factor invalidates these commissions. Amendments during proceedings do not inherently prejudice defendants and remain subject to appellate review. Regarding evidentiary standards, he noted international diversity in practice and observed many countries do not adhere to strict U.S. rules like hearsay exclusion; thus, these procedures do not breach Common Article 3 requirements.

Reaction to the ruling

The ruling permitted Hamdan’s prosecution, but solely within a judicial setting that guarantees procedural safeguards akin to those found in military courts-martial or commissions.

The enactment of the Military Commissions Act of 2006 soon sparked debate over which tribunals held jurisdiction to try cases such as Hamdan’s. The U.S. Department of Justice informed federal judges and detainees that habeas corpus petitions filed by foreign unlawful enemy combatants were beyond the scope of federal court authority.

This legislation achieved President Bush’s objective of securing explicit Congressional endorsement for military tribunals. Press Secretary Tony Snow publicly affirmed intentions to pursue legislative approval.

Within the Senate Republican caucus, opinions were split: Senators Arlen Specter and Lindsey Graham pushed for rapid authorization of these tribunals, whereas Senator John Warner urged a more measured, cautious approach.

On July 7, 2006, guidance from the United States Secretary of Defense mandated the application of Common Article 3 of the Geneva Conventions in detainee treatment protocols. Subsequently, the Bush administration declared that all detainees held by U.S. military forces—including those at Guantanamo Bay—must receive humane treatment consistent with Geneva Convention standards. Nonetheless, this policy did not explicitly encompass detainees under CIA custody and left uncertainties over the full extent of Common Article 3 protections.

Detainees held globally at locations such as Bagram Air Base and undisclosed sites explored leveraging the Supreme Court's decision to contest their conditions, contending that Geneva Convention safeguards might be broadly applicable. Expert opinions varied on the viability of this legal approach.

Consequences for executive authority theories

This verdict carries profound consequences for debates surrounding executive power and the unitary executive theory. It challenges the Bush administration’s legal justification for warrantless domestic surveillance conducted by the National Security Agency under the NSA electronic surveillance program, which had been defended as permissible despite requirements stipulated by the Foreign Intelligence Surveillance Act.

Dismissal and reissuance of charges

On June 5, 2007, charges against Hamdan and Canadian detainee Omar Khadr were dismissed. Military commission judges determined that under the Military Commissions Act, only individuals designated as "unlawful enemy combatants" could be tried, whereas both Hamdan and Khadr had been classified by their Combatant Status Review Tribunals simply as "enemy combatants," not unlawful ones.

In December 2007, a tribunal reclassified Hamdan as an "unlawful enemy combatant." By August 2008, he was convicted on a lesser offense and sentenced to 66 months; however, this was later reduced to five and a half months served. In November 2008, he was transferred to Yemen to complete his sentence and subsequently reunited with his family in Sana. His conviction was overturned in October 2012 by the U.S. Appeals Court for the District of Columbia, resulting in his acquittal.
