30-14-221. Investigations. (1) The department, for the purpose of conducting hearings and investigations that in the opinion of the department are necessary and proper for the exercise of the powers vested in the department by this part, shall at all reasonable times have access to any evidence concerning a person being investigated or proceeded against that relates to any matter under investigation or in question and the right to copy the evidence. The department may issue subpoenas requiring the attendance and testimony of witnesses and the production of any evidence that relates to any matter under investigation or in question before the department or before its duly authorized agent conducting the investigation. An agent, duly authorized by the department for those purposes, may administer oaths and affirmations, examine witnesses, and receive evidence. The attendance of witnesses and the production of evidence may be required from any place in this state at any designated place of hearing.

(2) Upon application by the department in a case of refusal to obey a subpoena issued to a person, a district court of this state, within the district where the inquiry is carried on or where a person guilty of refusal to obey is found, resides, or transacts business, has jurisdiction to issue to that person an order requiring the person to appear before the department or its duly authorized agent and to produce evidence if so ordered or to give testimony regarding the matter under investigation. Failure to obey the order of the court may be punished by the court as a contempt.

(3) A person may not be excused from attending and testifying or from producing books, records, correspondence, documents, or other evidence in obedience to the subpoena of the department on the ground that the testimony or evidence required of the person may tend to incriminate the person or subject the person to a penalty or forfeiture. However, compelled testimony or evidence or any information directly or indirectly derived from testimony or evidence may not be used against the witness in any criminal prosecution. This section does not prohibit the department from granting immunity from prosecution for or on account of any transaction, matter, or thing concerning which a witness is compelled to testify if the department determines, in its sole discretion, that the ends of justice would be served by granting immunity. Immunity may not extend to prosecution or punishment for false statements given pursuant to the subpoena.
