N.J. Stat. § 45:19-22
For the purpose of investigating the character, competency, integrity and methods of operation of applicants or licensees hereunder, or of the officers, directors, operatives, agents or employees of any applicant or licensee, the superintendent shall have the power to issue subpoenas and compel the attendance of witnesses. All such subpoenas shall be under the hand of the superintendent and the seal of the Department of State Police, and upon service thereof the witnesses shall be paid or tendered the fees to which they would be entitled if they were subpoenaed by a court of record. If the person duly subpoenaed shall fail to obey such subpoena without reasonable cause, or shall without cause refuse to be examined or answer any relevant or proper questions as to the character, actions or qualifications of such applicant or licensee or any of his employees he shall be guilty of a misdemeanor. The testimony of witnesses in any proceeding before the superintendent shall be under oath and the superintendent or a subordinate of the Department of State Police designated in writing by the superintendent may administer such oath, and willful false swearing in any such proceeding or inquiry shall constitute a high misdemeanor.
