United States Supreme Court
A U.S. citizen detained as an enemy combatant must be given notice of the factual basis for his classification and a fair opportunity to rebut the government's assertions before a neutral decision-maker.
Hamdi v. Rumsfeld held that while Congress had authorized the detention of enemy combatants, a U.S. citizen held as such retains due process rights, including notice of the charges against him and an opportunity to contest his detention before a neutral tribunal.
