The Detainee Treatment Act (DTA) was signed into law on December 30, 2005, and addresses many issues related to enemy combatants detained by the United States military. It places restrictions on the treatment and interrogation of detainees in U.S. custody, and it furnishes procedural protections for U.S. personnel accused of engaging in improper interrogation. DTA §§ 1002-1004, 119 Stat. 2739-2740. It also sets forth certain "procedures for status review of detainees outside the United States." § 1005, id., at 2740.
Subsections (a) through (d) of § 1005 direct the Secretary of Defense to report to Congress the procedures being used by CSRTs to determine the proper classification of detainees held in Guantanamo Bay, Iraq, and Afghanistan, and to adopt certain safeguards as part of those procedures.
Subsection (e) of § 1005, which is entitled "Judicial Review of Detention of Enemy Combatants," supplies the basis for the Government's jurisdictional argument. The subsection contains three numbered paragraphs. The first paragraph amends the judicial code as follows:
Paragraph (2) of subsection (e) vests in the Court of Appeals for the District of Columbia Circuit the "exclusive jurisdiction to determine the validity of any final decision of a [CSRT] that an alien is properly designated as an enemy combatant." Paragraph (2) also delimits the scope of that review. See §§ 1005(e)(2)(C)(i)-(ii), id., at 2742.
Paragraph (3) mirrors paragraph (2) in structure, but governs judicial review of final decisions of military commissions, not CSRTs. It vests in the Court of Appeals for the District of Columbia Circuit "exclusive jurisdiction to determine the validity of any final decision rendered pursuant to Military Commission Order No. 1, dated August 31, 2005 (or any successor military order)." § 1005(e)(3)(A), id., at 2743. Review is as of right for any alien sentenced to death or a term of imprisonment of 10 years or more, but is at the Court of Appeals' discretion in all other cases. The scope of review is limited to the following inquiries:
Finally, § 1005 contains an "effective date" provision, which reads as follows:
The original Act had an ambiguity about whether paragraph (1) of subsection (e) "shall apply" to claims pending on the date of enactment; a subsequent amendment clarified that it did.
