Hamdan v. Rumsfeld, 548 U.S. ___ (2006), is a United States Supreme Court case with numerous significant constitutional implications. The case questions the legality of Guantanamo military commissions set up by the Bush administration, whether the United States Congress has the authority to pass legislation preventing the Supreme Court from hearing the case of an accused combatant before his military commission takes place, and whether courts can enforce the articles of the 1949 Geneva Convention.
