Idaho Code § 36-1507

Any person dissatisfied by any action of the director made hereunder may appeal to any district court of competent jurisdiction, which shall require a trial de novo of all matters of fact and law. Such appeal shall be perfected by filing with the clerk of such district court, within thirty (30) days after the action of which complaint is made, a petition setting forth the action complained of. Such petition shall constitute the complaint, and summons may be issued thereon directed to the director as defendant, and served upon him. The pleadings thereafter shall conform to the practice in other civil proceedings. The court in its decree may sustain, modify, or reverse the action of the director, and shall render its opinion and judgment on the case appealed.
