http://sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/01/24/MNGDONO11O1.DTL One of the Bush administration's most far-reaching assertions of government power was revealed quietly last week when Attorney General Alberto Gonzales testified that habeas corpus -- the right to go to federal court and challenge one's imprisonment -- is not protected by the Constitution. "The Constitution doesn't say every individual in the United States or every citizen is hereby granted or assured the right of habeas,'' Gonzales told Sen. Arlen Specter, R-Pa., during a Senate Judiciary Committee hearing Jan. 17. Gonzales acknowledged that the Constitution declares "habeas corpus shall not be suspended unless ... in cases of rebellion or invasion the public safety may require it.'' But he insisted that "there is no express grant of habeas in the Constitution.'' Specter was incredulous, asking how the Constitution could bar the suspension of a right that didn't exist -- a right, he noted, that was first recognized in medieval England as a shield against the king's power to dispatch troublesome subjects to royal dungeons.
