Washington Constitution Art. 4, § 7. Exchange of Judges--Judge Pro Tempore

The judge of any superior court may hold a superior court in any county at the request of the judge of the superior court thereof, and upon the request of the governor it shall be his or her duty to do so. A case in the superior court may be tried by a judge pro tempore either with the agreement of the parties if the judge pro tempore is a member of the bar, is agreed upon in writing by the parties litigant or their attorneys of record, and is approved by the court and sworn to try the case; or without the agreement of the parties if the judge pro tempore is a sitting elected judge and is acting as a judge pro tempore pursuant to supreme court rule. The supreme court rule must require assignments of judges pro tempore based on the judges' experience and must provide for the right, exercisable once during a case, to a change of judge pro tempore. Such right shall be in addition to any other right provided by law. However, if a previously elected judge of the superior court retires leaving a pending case in which the judge has made discretionary rulings, the judge is entitled to hear the pending case as a judge pro tempore without any written agreement.
