WASHINGTON - The military trials bill approved by Congress lends legislative support for the first time to broad rules for the detention, interrogation, prosecution and trials of terrorism suspects far different from those in the familiar American criminal justice system.

President Bush's argument that the government requires extraordinary power to respond to the unusual threat of terrorism helped him win final support for a system of military trials with highly truncated defendant's rights. The United States used similar trials on just four occasions: during the country's revolution, the Mexican-American War, the Civil War and World War II.

Included in the bill, passed by Republican majorities in the Senate Thursday and the House on Wednesday, are unique rules that bar terrorism suspects from challenging their detention or treatment through traditional habeas corpus petitions. They allow prosecutors, under certain conditions, to use evidence collected through hearsay or coercion to seek criminal convictions.

The bill rejects the right to a speedy trial and limits the traditional right to self-representation by requiring that defendants accept military defense attorneys. Panels of military officers need not reach unanimous agreement to win convictions, except in death penalty cases, and appeals must go through a second military panel before reaching a federal civilian court.

By writing into law for the first time the definition of an "unlawful enemy combatant," the bill empowers the executive branch to detain indefinitely anyone it determines to have "purposefully and materially" supported anti-U.S. hostilities. Only foreign nationals among those detainees can be tried by the military commissions, as they are known, and sentenced to decades in jail or put to death.

The measure would broaden the definition of enemy combatants beyond the traditional definition used in wartime, to include non-citizens living legally in the United States as well as those in foreign countries and anyone determined to be an enemy combatant under criteria defined by the president or secretary of Defense.

At the same time, the bill immunizes U.S. officials from prosecution for cruel, inhumane or degrading treatment of detainees who the military and the CIA captured before the end of last year. It gives the president a dominant but not exclusive role in setting the rules for future interrogations of terrorism suspects.

Written largely, but not completely, on the administration's terms, with passages that give executive branch officials discretion to set details or divert from its protections, the bill is meant to provide what Bush said Thursday are "the tools" needed to handle terrorism suspects U.S. officials hope to capture.

For more than 57 months after the 2001 terrorist attacks on the World Trade Center and the Pentagon, Bush maintained that he did not need congressional authorization of such tools. But the Supreme Court decided otherwise in June, declaring the administration's detainee treatment and trial procedures illegal, and ruling that Bush must first seek Congress's approval.

Now Bush has received much of the authority he desired from party loyalists and a handful of Democrats on Capitol Hill. "The American people need to know we're working together," Bush told senators before Thursday's vote.

But Tom Malinowski, the Washington office director for Human Rights Watch, said that Bush's motivation is partly to protect his reputation by gaining congressional endorsement of controversial actions already taken. "He's been accused of authorizing criminal torture in a way that has hurt America and could come back to haunt our troops. One of his purposes is to have Congress stand with him in the dock," Malinowski said.

The bill contains some protections unavailable to the eight Nazi saboteurs who came ashore in the United States in 1942 and were captured two weeks later. Six were executed that year after a closed military trial on the fifth floor of Justice Department headquarters. That proceeding was upheld by the Supreme Court in a decision it explained two months after the electrocutions.

Under the new procedures, trials are supposed to be open, but can be closed to protect individuals or information expected to harm national security. Defendants have a right to be present, unless they are disruptive, and have the right to examine and respond to the evidence against them. Proof of guilt must exceed a reasonable doubt.

Many constitutional experts say, however, that the bill pushes at the edges of so much settled U.S. law that its passage will not be the last word on America's detainee policies.

"This is a full-employment act for lawyers," said Deborah Perlstein, who directs the U.S. Law and Security Program at the New York-based nonprofit group Human Rights First.

Former White House associate counsel Bradford Berenson, a supporter of the bill and an author of the rules struck down by the Supreme Court, agreed. "Some of the most creative legal minds are going to be devoted to poking holes in this," he said.

Anticipating court challenges, the administration attempted to make the bill bulletproof by including provisions that would sharply restrict judicial review and limit the application of international treaties - signed by Washington - that govern the rights of wartime detainees.

This is an important question and details are important.

Staff at a Republican congressman's told me empathecially that bill does not affect citizens and was unaware of issue.
