Upon the failure or refusal of any witness to obey any subpoena, the commissioner may petition the district court, and, upon a proper showing, the court may enter an order compelling the witness to appear and testify or produce documentary evidence. Failure to obey such an order of the court shall be punishable as a contempt of court.
