Wyo. Stat. § 6-6-202
Whenever a nuisance exists as defined in this article, the county attorney or any citizen of the county may maintain an action in the name of the state of Wyoming upon the relation of the county attorney or citizen, to perpetually enjoin the nuisance, the person maintaining the nuisance, and the owner or agent of the building or ground upon which the nuisance exists. In the action, the court shall, upon the presentation of a petition alleging that the nuisance complained of exists, allow a temporary writ of injunction without bond, if it appears to the satisfaction of the court by evidence in the form of affidavits, depositions, oral testimony or otherwise. Three (3) days notice in writing shall be given the defendant of the application, and, if then continued at his instance, the writ as prayed shall be granted as a matter of course. When an injunction has been granted, it shall be binding on the defendant throughout the judicial district in which it was issued, and any violation of the provisions of injunction shall be a contempt.
