Wash. Rev. Code § 50.32.010
The commissioner shall establish one or more impartial appeal tribunals, each of which shall consist of an administrative law judge appointed under chapter 34.12 RCW who shall decide the issues submitted to the tribunal. No administrative law judge may hear or decide any disputed claim in any case in which he or she is an interested party. Wherever the term "appeal tribunal" or "the appeal tribunal" is used in this title the same refers to an appeal tribunal established under the provisions of this section. Notice of any appeal or petition for hearing taken to an appeal tribunal in any proceeding under this title may be filed with such agency as the commissioner may by regulation prescribe.
