MAGISTRATE JUDGES. Judicial officers who assist U.S. district judges in getting cases ready for trial, who may decide some criminal and civil trials when both parties agree to have the case heard by a magistrate judge instead of a judge. Congress created the judicial office of federal magistrate in 1968. In 1990, the position title was changed to magistrate judge. The judges of each district appoint one or more magistrate judges, who discharge many of the ancillary duties of district judges so that the judges can handle more trials.
