According to the United States Department of Defense, there were five dozen Pakistan detainees in Guantanamo prior to May 15, 2006. The Guantanamo Bay detention camp was opened on January 11, 2002. In the summer of 2004, following the United States Supreme Court's ruling in Rasul v. Bush, the Department of Defense stopped transferring men and boys to Guantanamo. The Supreme Court determined that the detainees had to be given a chance to challenge their detentions in an impartial tribunal.
