N.J. Stat. § 34:13B-21
The Board of Arbitration shall promptly proceed to arbitrate the matters submitted to it. It shall promptly hold hearings and shall have the power to administer oaths and compel by subpoena the attendance of witnesses and the furnishing and production by any person of such information, books, records, papers and documents as may be necessary to a determination of the issue or issues in dispute. If a person subpoenaed to attend any hearing refuses or fails to appear or to be examined, or to answer any question or to produce any books, records, papers and documents when ordered so to do by the Board of Arbitration, such board may apply to the Superior Court to compel the person to comply forthwith with the subpoena, direction or order of the board. Both parties to the dispute shall be afforded an opportunity to be present at the hearing, both personally and by counsel, and to present such oral and documentary evidence as the Board of Arbitration shall deem relevant to the issue or issues in controversy.
