When the Supreme Court decided in 2004 in Rasul v. Bush that detainees being held in Guantanamo Bay had the right to challenge their detentions in an American court, Congress and the president passed the Detainee Treatment Act, which prevented later, similar habeas petitions from being filed in American courts. Last year, when the Supreme Court decided in Hamdan v. Rumsfeld that the president did not have the authority to convene military commissions, Congress gave the president the authority to convene military commissions in the Military Commissions Act.
