Wash. Admin. Code § 478-121-200
All conduct proceedings under this code shall be conducted in accordance with chapter 34.05 RCW, Administrative Procedure Act and constitutional due process. If there is an irresolvable conflict between this code and the Administrative Procedure Act or constitutional due process, the Administrative Procedure Act and constitutional due process shall supersede these rules.
In applying this code, due consideration shall be given to the fact that the conduct process is administrative and not judicial in nature and that the rules of civil procedure only apply to the extent set forth in this code or in chapter 34.05 RCW. In formal proceedings pursuant to RCW 34.05.413 through 34.05.476, the University of Washington adopts the model rules of procedure, chapter 10-08 WAC, Model rules of procedure. In the case of a conflict between the model rules of procedure and these procedural rules, the procedural rules adopted in these rules shall govern.
Informal settlements may be conducted under the authority of RCW 34.05.060.
