Iowa Code Title XVI. Criminal Law and Procedure [Chs. 687-916] § 906.8. Subpoena powers

The board shall have power to issue subpoenas requiring the attendance of such witnesses and the production of such records, books, papers and documents as it may deem necessary for investigation of the case of any person before it. Subpoenas so issued may be served by any peace officer, in the same manner as similar processes in the district court. Any person who testifies falsely or fails to appear when subpoenaed, or fails or refuses to produce such material pursuant to the subpoena, shall be subject to the same orders and penalties to which a person before a court is subject. Any district court in this state, upon application of the board, may compel the attendance of witnesses, the production of such material, and the giving of testimony before the board, by an attachment for contempt or otherwise in the same manner as production of evidence may be compelled before such district court.
