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, partnership, or organization from persisting in the doing of any acts constituting a violation of the provisions of this chapter. Such action shall be brought in the district court of the county in which the act or acts or some of them are claimed to have been or are being committed, by filing a complaint setting forth the 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 the 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 the defendant from thereafter committing the act or similar acts.
