The Judges

Idaho has a District Court for the judicial district and a Magistrate Court. Magistrate judges are appointed by a district magistrates commission and then face a retention election; both are state judicial officers, not county officials. The county's own site names its District Court Judge and Magistrate Judge but does not state the judicial district number.
