The Obama administration has asked an appeals court to dismiss a lawsuit accusing former Bush administration attorney John Yoo of authorizing the torture of a terrorism suspect, saying federal law does not allow damage claims against lawyers who advise the president on national security issues.Such lawsuits ask courts to second-guess presidential decisions and pose "the risk of deterring full and frank advice regarding the military's detention and treatment of those determined to be enemies during an armed conflict," Justice Department lawyers said Thursday in arguments to the Ninth U.S. Circuit Court of Appeals in San Francisco.
