Idaho Code § 52-402
The attorney general, prosecuting attorney, or any private resident citizen of the county may maintain an action of an equitable nature, as relator, in the name of the state of Idaho, to abate a moral nuisance, perpetually to 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 prior to the issuance of a restraining order or a temporary injunction, with good and sufficient surety to be approved by the court or clerk thereof, in the sum of not less than five hundred dollars ($500), to secure to the party enjoined the damages he may sustain if such action is wrongfully brought, not prosecuted to final judgment, or is dismissed, or is not maintained, or if it is finally decided that the restraining order or temporary injunction ought not to have been granted. The party enjoined shall have recourse against said bond for all damages suffered, including damages to his property, person, or character and including reasonable attorney's fees incurred by him in making defense to said action. No bond shall be required of the prosecuting attorney or the attorney general, and no action shall be maintained against the public official for his official action when brought in good faith.
