The arbitration panel may administer oaths, require the attendance of witnesses, and the production of such books, papers, contracts, agreements and documents as may be deemed by it material to a just determination of the issues in dispute, and for such purpose may issue subpoenas. If any person refuses to obey a subpoena, or refuses to be sworn or to testify, or if any witness, party or attorney is guilty of any contempt while in attendance at any hearing, the arbitration panel may, or the attorney general if requested shall, invoke the aid of any circuit court within the jurisdiction in which the hearing is being held, which court shall issue an appropriate order. Any failure to obey the order may be punished by the court as contempt.
