When it comes to national security-fighting wars and defending the nation-the courts have long deferred to the president and Congress. After 9/11, the Bush administration counted on judges staying out of the way as it figured out what to do with suspects rounded up in the War on Terror. The administration built a prison at the U.S. Navy base at Guantánamo Bay, Cuba, because it was secure, but also because administration lawyers figured (and legal precedents suggested) that American courts had no power to meddle there. Just as the true believers in the Bush White House have done so often, they overreached.

As Charles Fried, solicitor general in the Reagan administration, has reportedly put it, the Bush administration "badly overplayed a winning hand." Bush and his advisers so flouted ordinary, and old, ideas of justice and liberty that they put the Supreme Court in an impossible position: either rubber-stamp denials of due process to detainees who say they were seized by mistake, or step in and create a new set of problems by making rules on a slow, messy, case-by-case basis. In effect, that’s what happened last week when the court ruled in Boumediene v. Bush. If ever there was proof of the adage "hard cases make bad law," this is it.
