The Supreme Court today delivered a stunning rebuke to the Bush administration over its plans to try Guantanamo detainees before military commissions, ruling that the commissions violate U.S. law and the Geneva Conventions governing the treatment of war prisoners.
In a 5-3 decision, the court said the trials were not authorized by any act of Congress and that their structure and procedures violate the Uniform Code of Military Justice (UCMJ) and the four Geneva Conventions signed in 1949.
