Wash. Admin. Code § 478-121-250
The following evidentiary provisions apply to conduct proceedings under this code. 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 rules of evidence only apply to the extent set forth in this code or in chapter 34.05 RCW. The university has also developed agency-level guidance regarding its interpretations of these rules, including in Student Governance and Policies, chapters 209 and 210.
While brief adjudicative proceedings do not require the application of rules of evidence, the conduct officer will be guided by the principles underlying the Washington state rules of evidence when they do not conflict with the code or relevant university policies.
