The executive council, in any investigation held by it, may issue subpoenas for witnesses and for the production of records, books, papers, and other evidence. If a witness, duly subpoenaed, refuses to appear, or refuses to testify, or otherwise refuses to comply with said subpoena, such fact shall be certified by such council to the district court or judge of the county where the hearing is being held and said court or judge shall proceed with said refusal as though the same had occurred in a legal proceeding before said court or judge.
