A team of administration lawyers concluded in a March 2003 legal memorandum that President Bush was not bound by either an international treaty prohibiting torture or by a federal antitorture law because he had the authority as commander in chief to approve any technique needed to protect the nation's security.

The memo, prepared for Defense Secretary Donald H. Rumsfeld, also said that any executive branch officials, including those in the military, could be immune from domestic and international prohibitions against torture for a variety of reasons.

One reason, the lawyers said, would be if military personnel believed that they were acting on orders from superiors "except where the conduct goes so far as to be patently unlawful."

"In order to respect the president's inherent constitutional authority to manage a military campaign," the lawyers wrote in the 56-page confidential memorandum, the prohibition against torture "must be construed as inapplicable to interrogation undertaken pursuant to his commander-in-chief authority."

The review stemmed from concerns raised by Pentagon lawyers and interrogators at Guantánamo after Mr. Rumsfeld approved a set of harsher interrogation techniques in December 2002 to use on a Saudi detainee, Mohamed al-Kahtani, who was believed to be the planned 20th hijacker in the Sept. 11 terror plot.

The memo showed that not only lawyers from the Defense and Justice departments and the White House approved of the policy but also that David S. Addington, the counsel to Vice President Dick Cheney, also was involved in the deliberations. The State Department lawyer, William H. Taft IV, dissented, warning that such a position would weaken the protections of the Geneva Conventions for American troops.

The adjective "severe," the report said, "makes plain that the infliction of pain or suffering per se, whether it is physical or mental, is insufficient to amount to torture. Instead, the text provides that pain or suffering must be `severe.' " The report also advised that if an interrogator "has a good faith belief his actions will not result in prolonged mental harm, he lacks the mental state necessary for his actions to constitute torture."

The report also said that interrogators could justify breaching laws or treaties by invoking the doctrine of necessity. An interrogator using techniques that cause harm might be immune from liability if he "believed at the moment that his act is necessary and designed to avoid greater harm."

Jamie Fellner, the director of United States programs for Human Rights Watch, said Monday, "We believe that this memo shows that at the highest levels of the Pentagon there was an interest in using torture as well as a desire to evade the criminal consequences of doing so."

The March memorandum also contains a curious section in which the lawyers argued that any torture committed at Guantánamo would not be a violation of the anti-torture statute because the base was under American legal jurisdiction and the statute concerns only torture committed overseas. That view is in direct conflict with the position the administration has taken in the Supreme Court, where it has argued that prisoners at Guantánamo Bay are not entitled to constitutional protections because the base is outside American jurisdiction.
