What it does
This law establishes a system of military commissions — special tribunals — to try non-U.S. citizens classified as "unlawful enemy combatants" for war crimes and related offenses. It defines who qualifies as a lawful or unlawful enemy combatant, sets out trial procedures including evidence rules, voting thresholds for conviction, and an appeals process up to the U.S. Supreme Court. It also strips federal courts of jurisdiction to hear habeas corpus petitions filed by alien detainees held by the United States, bars detainees from invoking the Geneva Conventions as a source of rights in U.S. courts, and authorizes the President to interpret the meaning of the Geneva Conventions for U.S. purposes.
Who benefits
U.S. military and intelligence personnel who gain legal protection and mandatory government-funded counsel for authorized interrogation activities. The executive branch, which gains authority to define "unlawful enemy combatant" and interpret Geneva Convention obligations. Victims of war crimes who gain a formal legal mechanism for prosecution. Congress, which gains annual reporting requirements on commission proceedings. U.S. government contractors and agents involved in detention operations who receive expanded legal protections.
Who is hurt
Non-U.S. citizen detainees held by the United States who lose the ability to challenge their detention in federal court via habeas corpus. Detainees who can no longer invoke the Geneva Conventions as a source of rights in any U.S. court. Defense attorneys and civil liberties organizations that lose a key legal avenue for challenging detention conditions. Foreign nationals detained since September 11, 2001, who are retroactively affected by the habeas-stripping provisions. International allies and treaty partners who may view U.S. unilateral reinterpretation of the Geneva Conventions as undermining multilateral legal frameworks.
Supporters argue
Supporters argue that traditional civilian courts and standard court-martial procedures are ill-suited to handle classified intelligence, non-state combatants, and battlefield evidence that cannot be disclosed without endangering national security. They contend the Act provides meaningful procedural protections — including defense counsel, a prohibition on evidence obtained by torture, a two-thirds conviction threshold, and full appellate review up to the Supreme Court — while giving the government a workable legal framework to prosecute terrorists for serious war crimes. They further argue that the 2001 AUMF and the President's Commander-in-Chief authority, combined with explicit congressional authorization, place this squarely in Justice Jackson's Zone 1 under Youngstown, representing the apex of federal power.
Opponents argue
Opponents argue that stripping federal courts of habeas corpus jurisdiction for all alien detainees — including those held indefinitely without trial — directly conflicts with Boumediene v. Bush (2008), in which the Supreme Court later struck down a nearly identical provision and held that Guantanamo detainees have constitutional habeas rights. They contend that barring detainees from invoking the Geneva Conventions, combined with presidential authority to unilaterally reinterpret those treaties, undermines the rule of law and the separation of powers by concentrating treaty interpretation in the executive branch alone. They also argue that the broad, executive-controlled definition of "unlawful enemy combatant" creates a risk of indefinite detention with insufficient judicial oversight, in tension with the due process principles affirmed in Hamdi v. Rumsfeld (2004).
Constitutional context
The habeas-stripping provision in Section 7 was directly at issue in Boumediene v. Bush (2008), where the Supreme Court held that the Suspension Clause (Art. I, §9, cl. 2) guarantees habeas rights to Guantanamo detainees and that Congress cannot strip that jurisdiction without a constitutionally adequate substitute. The Act's military commission framework also implicates Hamdan v. Rumsfeld (2006), which held that commissions must comply with the UCMJ and Geneva Conventions — a ruling this Act directly responds to — and Hamdi v. Rumsfeld (2004), which required meaningful due process for enemy combatant determinations.
Checks and balances
The executive branch gains significant authority — including the power to define "unlawful enemy combatant" and interpret the Geneva Conventions — but Congress checks this through mandatory annual reporting, the statutory commission framework itself, and preserved appellate review by the D.C. Circuit and Supreme Court; the judiciary retains the ultimate check, as Boumediene (2008) demonstrated by striking down the Act's habeas-stripping provision.
Historical precedent
The Military Commissions Act of 2006 was a direct congressional response to Hamdan v. Rumsfeld (2006), in which the Supreme Court struck down the Bush administration's earlier military commission system as inconsistent with the UCMJ and Geneva Conventions; the Act's habeas-stripping provision was subsequently struck down in Boumediene v. Bush (2008).
