This 2006 Supreme Court case involved an alien, who was detained at Guantanamo Bay, Cuba, and charged with various terrorism-related offenses and was designated for trial before a military commission. The Supreme Court held the military commission was not expressly authorized by any congressional act; its procedures violated the Uniform Code of Military Justice (UCMJ); and
it did not satisfy Geneva Conventions.
