In his testimony before the House Judiciary Subcommitte on the Constitution, Civl Rights, and Civil Liberties, Jonathan Hafetz addresses the Bush Administration’s threat to habeas corpus at the Guantánamo Bay Naval Station. He divides his discussion into five parts. First, he recalls the historical importance of habeas corpus and its function in the Constitution. Second, he outlines the continuing infringement of habeas corpus rights of Guantánamo detainees despite two Supreme Court decisions reinforcing the importance of habeas review. Third, Mr. Hafetz’s testimony holds Guantánamo as an example of how habeas corpus ensures that the United States follows correct detainment procedure. Fourth, he argues that restoring the legitimacy of habeas corpus will aid the development of an effective counterterrorism policy. And lastly, Mr. Hafetz’s report highlights the shortcomings of Administration’s reasoning against providing habeas for Guantánamo detainees, and why the environment of a “Global War on Terrorism” makes such review all the more crucial.
