The prisoner review board shall have power to issue subpoenas requiring the attendance of any witnesses and the production of any records, books, papers and documents that it considers necessary for the investigation of the issues before it. Subpoenas may be signed and oaths administered by any member of the board. Subpoenas so issued may be served by any law enforcement officer, in the same manner as similar process in the district court. Any person who testifies falsely, fails to appear when subpoenaed or fails or refuses to produce 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 of this state, upon application of the board, may in its discretion compel the attendance of witnesses, the production of 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 the district court.
