On Thursday, the Supreme Court ruled that terrorism suspects being held by the United States in Guantánamo Bay, Cuba, may challenge their detention in federal court.
By a 5-4 vote, the court said that the prisoners, foreign nationals, had been unconstitutionally denied the right to file habeas corpus petitions -- that is, the right to demand to know the reason they are being held, and challenge it. According to Justice Anthony Kennedy, writing for the majority, the Constitution is "designed to survive, and remain in force, in extraordinary times." Chief Justice John Roberts was among the four dissenters. Justice Antonin Scalia, another dissenter, warned that "the nation will live to regret what the court has done today."
