Idaho Code § 1-703
Where there is more than one (1) judge in any district, the jurisdiction of the respective judges of said district shall be equal and coextensive with the boundaries of the district. In each judicial district there shall be an administrative judge elected by a majority of the district judges within the district to serve for a period of time as provided by rules of the Idaho supreme court. In the event a majority of the district judges cannot agree as to who shall be the administrative judge, then the appointment of the administrative judge shall be by a majority of the Idaho supreme court justices for a period of time as provided by rules of the Idaho supreme court. The administrative judge is hereby granted all powers and duties heretofore or hereafter granted to the senior district judge, and the administrative judge shall apportion the business of such district among such judges as equally as may be, but any judge shall have full power to hold terms of court, transact judicial business, make orders, grant or refuse writs and generally exercise all the powers of a district judge without the concurrence of the other judge or judges. The administrative judge shall receive an annual salary in an amount of three thousand dollars ($3,000) greater than the annual salary of a district judge to compensate for the additional duties of the office.
