Upon the failure of any person to comply with a subpoena issued by the Tax Commission pursuant to Section 306 (7), the Commission shall apply to the Tribal Court for issuance of a show cause order. The show cause order shall be issued by the Tribal Court forthwith, without notice of hearing, unless the Court finds that the subpoena lawfully issued or that the subpoena was not properly served. The show cause order, which shall be promptly served, shall state that the person against whom the subpoena was issued shall comply with the subpoena within ten days or show cause why he should not be held in contempt of court.
