The Justice Department indicated that it was not backing away from the argument used by the Bush administration that courts should use national security concerns to block a lawsuit brought by an Islamic group that says its rights had been violated. Department lawyers filed papers with a Federal District Court in San Francisco asking for a stay in a judge’s ruling that the “state secrets” doctrine could not be used in the Islamic group’s lawsuit. The group, al-Haramain, has argued that its officers and lawyers were illegally wiretapped in a secret surveillance program by the National Security Administration. The Justice Department under President Bush invoked the state secrets doctrine in asking the court to dismiss the case.
