Wash. Rev. Code § 29A.72.080
Any persons, including the attorney general or either or both houses of the legislature, dissatisfied with the ballot title or summary for a state initiative or referendum may, within five days from the filing of the ballot title in the office of the secretary of state, appeal to the superior court of Thurston county by petition setting forth the measure, the ballot title or summary, and their objections to the ballot title or summary and requesting amendment of the ballot title or summary by the court. Saturdays, Sundays, and legal holidays are not counted in calculating the time limits contained in this section.
A copy of the petition on appeal together with a notice that an appeal has been taken shall be served upon the secretary of state, upon the attorney general, and upon the person proposing the measure if the appeal is initiated by someone other than that person. Upon the filing of the petition on appeal or at the time to which the hearing may be adjourned by consent of the appellant, the court shall accord first priority to examining the proposed measure, the ballot title or summary, and the objections to that ballot title or summary, may hear arguments, and shall, within five days, render its decision and file with the secretary of state a certified copy of such ballot title or summary as it determines will meet the requirements of RCW 29A.72.060. The decision of the superior court shall be final. Such appeal shall be heard without costs to either party.
