New Jersey Statutes Title 34. Labor and Workmen's Compensation 34 § 13A-17

The arbitrator may administer oaths, require the attendance of witnesses, and the production of such books, papers, contracts, agreements and documents as he may deem material to a just determination of the issues in dispute, and for such purpose may issue subpenas. If any person refuses to obey a subpena, 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 arbitrator may, or the Attorney General if requested shall, invoke the aid of the Superior Court within the county 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.
