Washington Revised Code Title 7. Special Proceedings and Actions § 7.48.058. Maintaining action to abate moral nuisance--Bond

The attorney general, prosecuting attorney, city attorney, city prosecutor, or any citizen of the county may maintain an action of an equitable nature in the name of the state of Washington upon the relation of such attorney general, prosecuting attorney, city attorney, city prosecutor, or citizen, to abate a moral nuisance, to perpetually enjoin all persons from maintaining the same, and to enjoin the use of any structure or thing adjudged to be a moral nuisance.

If such action is instituted by a private person, the complainant shall execute a bond to the person against whom complaint is made, with good and sufficient surety to be approved by the court or clerk thereof, in the sum of not less than five hundred dollars, to secure to the party enjoined the damages he or she may sustain if such action is wrongfully brought, and the court finds there was no reasonable grounds or cause for said action and the case is dismissed for that reason before trial or for want of prosecution.  No bond shall be required of the attorney general, prosecuting attorney, city attorney, or city prosecutor, and no action shall be maintained against such public official for his or her official action when brought in good faith.
