Idaho Code § 54-1524
The board or any resident citizen may maintain an action in equity in the name of the state of Idaho to enjoin perpetually any person, firm, company, corporation or partnership from persisting in the doing of any acts constituting a violation of this chapter. Such action shall be brought in the district court of the county in which said act or acts or some of them are claimed to have been or are being committed, by filing a complaint setting forth said acts. The court, or a judge thereof at chambers, if satisfied from such complaint or by affidavits that the acts complained of have been or are being committed and will probably be persisted in, may issue a temporary writ enjoining the defendant from the commission of any such act or acts pending final disposition of the cause. The cause shall proceed as in other cases for injunction. If at the trial the commission of said act or acts by the defendant be established, and the court further finds that it is probable that defendant will continue therein or in similar violations, the court, or a judge thereof at chambers, shall enter a decree perpetually enjoining said defendant from thereafter committing said or similar acts.
