N.J. Stat. § 30:11-18
Notice of the pending revocation, suspension, or denial of a license together with a specification of charges shall be sent to the applicant or the licensee by registered mail. Denial, suspension or revocation shall become effective 30 days after mailing, unless the applicant or licensee within such 30-day period shall meet the requirements of the department or shall give written notice to the department of his desire for a hearing, in which case, the denial, suspension or revocation shall be held in abeyance until the hearing has been concluded and a final decision rendered; provided, however, that such applicant or licensee may appeal from such denial, suspension or revocation to any court having jurisdiction of such matters.
