Idaho Code § 26-2236
The director shall have the power to issue subpoenas as necessary to determine whether a person has violated any provision of this act, rule or order thereunder, to swear witnesses and to take the testimony of any person by deposition, with the same fees and mileage and in the same manner as prescribed by law in judicial procedure in district courts of this state in civil cases. Any party to a proposed revocation or suspension of a license shall have the right of subpoena to compel the attendance of witnesses and produce all reasonably necessary books and writings on his behalf. In case any witness shall fail or refuse to comply with a subpoena to appear before the director, the clerk of the district court of the county in which the administrative proceedings are held shall, upon demand of the director, issue a subpoena reciting the demand therefor and summoning the witness to appear and testify at a time and place fixed; and violation of such subpoena or disobedience thereto shall be deemed and punished as a violation of a subpoena issued by the district court.
