Consistent with RCW 34.05.425, any presiding officer or reviewing officer is subject to disqualification for bias, prejudice, interest, or any other applicable cause. Any party may petition for the disqualification of an individual promptly after receipt of notice indicating that the individual will preside or, if later, promptly upon discovering facts establishing grounds for disqualification. The individual whose disqualification is requested shall determine whether to grant the petition, stating facts and reasons for the determination. An appropriate individual will then be substituted as a presiding or reviewing officer.
