Wash. Admin. Code § 132T-16-016
The election officer shall designate at least one inspector for each polling place to observe the conduct of the election. Any organization whose name shall appear on the ballot in the election shall also be entitled to have one inspector present at each polling place to observe the conduct of the election. Each organization shall also be entitled to have an inspector present at the college district office for the counting of the ballots cast. Such inspectors must refrain from electioneering during the election. They may challenge the eligibility of any person to vote in the election, and, upon such challenge, the ballot of that person shall be treated as provided in these rules. Inspectors shall also report in writing to the chief election officer any conduct which they observe in the course of balloting which they believe may have improperly affected the result of the voting at the polling place at which they serve as observers.
