The Supreme Court today refused to give a hearing to a German man who says he was wrongly abducted, imprisoned and tortured by the CIA in a case of mistaken identity.Khaled Masri sued the CIA two years ago and sought damages for his five-month ordeal in a U.S.-run prison in Afghanistan.But Bush administration prosecutors said his lawsuit should not be heard because it could expose "state secrets," and two lower courts ordered it dismissed.He appealed to the Supreme Court and argued that the government was using the state secrets doctrine to cover up its wrongdoing.Without explaining their reasons, the justices said today that they would not hear his appeal in Masri vs. United States.More than 50 years ago, the Supreme Court ruled that some evidence could be shielded by the government to protect the nation's security, but the justices have not clarified the reach of that doctrine.Masri's case has gotten wide attention in Europe, and it has been the subject of a continuing investigation by the German government. Two years ago, German Chancellor Angela Merkel said after a meeting with Secretary of State Condoleezza Rice that U.S. officials admitted that Masri "had been erroneously taken."
