Hamdan v. United States, No. 11-1257 (D.C. Cir. 2012)
Annotate this CaseThis case raised questions about the scope of the Executive's authority to prosecute war crimes under current federal statutes. This particular dispute involved the military commission conviction of petitioner, an al Qaeda member who worked for Osama bin Laden. The court concluded that: (1) despite petitioner's release from custody, this case was not moot; (2) consistent with Congress's stated intent and so as to avoid a serious Ex Post Facto Clause issue, the court interpreted the Military Commissions Act of 2006, 10 U.S.C. 821, not to authorize retroactive prosecution of crimes that were not prohibited as war crimes triable by military commission under U.S. law at the time the conduct occurred; and (3) when petitioner committed the relevant conduct from 1996-2001, Section 821 provided that military commissions may try violations of the "law of war." Because the court read the Act not to retroactively punish new crimes, and because material support for terrorism was not a pre-existing war crime under Section 821, petitioner's conviction for material support for terrorism could not stand. The court reversed the judgment of the Court of Military Commission Review and directed that petitioner's conviction for material support for terrorism be vacated.
