(5) Any hearing provided for in this section may be conducted by the director, or by any member of the department acting on behalf of the director, or the director may designate hearing officers who shall have the power and authority to conduct such hearings in the name of the director at any time and place. A verbatim record of the proceedings of such hearings shall be taken and filed with the director, together with findings of fact and conclusions of law made by the director or hearing officer. The director may subpoena witnesses, and any witness who is subpoenaed shall receive the same fees as in civil actions in the district court and mileage as provided in section 81-1176. In case of contumacy or refusal to obey a notice of hearing or subpoena issued under this section, the district court of Lancaster County shall have jurisdiction, upon application of the director, to issue an order requiring such person to appear and testify or produce evidence as the case may require. Failure to obey such order of the court may be punished by such court as contempt. If requested to do so by any party concerned with such hearing, the full stenographic notes, or tapes of an electronic transcribing device, of the testimony presented at such hearing shall be taken and filed. The stenographer shall, upon the payment of the stenographer's fee allowed by the court, furnish a certified transcript of all or any part of the stenographer's notes to any party to the action requiring and requesting such notes.
