The memo signed by Gordon England, the No. 2 official in the Defense department, followed a June 29 Supreme Court ruling that struck down as illegal the military tribunal system set up by the Bush administration to try foreign terrorism suspects held at the U.S. naval base at Guantanamo Bay, Cuba. The United States previously has determined that certain prisoners taken in Washington's war on terrorism are not deserving of all of the protections of the Geneva Conventions -- international agreements governing the treatment of prisoners of war. The memo was made public on the day Congress began hearings on how to proceed in trying Guantanamo prisoners after the high court ruling.
