Al-Marri v. Pucciarelli

Al-Marri (defendant), a lawful U.S. resident alien indicted for fraud and lying to the FBI, was declared an enemy combatant by presidential order under the AUMF and transferred to military custody; the government's supporting declaration alleged he trained at an al-Qaeda camp, met Osama bin Laden, and entered the U.S. before 9/11 to act as a sleeper agent. His habeas petition was denied by the district court, a Fourth Circuit panel reversed, and the full court granted rehearing en banc.
