N.J. Stat. § 24:16B-49
Before declining to grant a license or conditioning or limiting a license, or suspending or revoking a license previously granted, the secretary or his duly authorized agent or employee shall give notice to the applicant or licensee personally or by certified mail addressed to his last known address, and afford him an opportunity to appear and be heard with respect thereto at a time and place specified in such notice. Such applicant or licensee shall have the right to be heard in person or by attorney, and to offer evidence pertinent to the subject of the hearing, and to that end to invoke the powers of the secretary with respect to the compulsory attendance of witnesses and the production of books, accounts, papers, records and documents by subpoena. The secretary may make such other rules, as may be reasonable and appropriate, regulating the manner, form, time, terms and conditions of such proceedings. The secretary or his duly authorized agent or employee shall not be bound in such proceedings to apply the technical rules of evidence prevailing in a court of law.
