Common Law Writs
A body of legal remedies, sometimes called extraordinary remedies or common law writs ,
was a part of Anglo-English law at the time of adoption of the Constitution, and incorporated by the Constitution. Only one of these, however, habeas corpus , is explicitly mentioned in the Constitution, and the rest would seem to be included by the Ninth Amendment as among the unenumerated rights. They have been deprecated in recent decades, and there is a movement to resurrect them.
