N.J. Stat. § 26:2G-27
The commissioner after a hearing may deny, revoke, or suspend any certificate of approval granted under authority of this act to any person, firm, partnership, corporation or association violating the provisions hereof or the rules and regulations promulgated hereunder.
Notice of the pending revocation, suspension, or denial of a certificate of approval together with a specification of charges shall be sent to the applicant or holder of a certificate of approval by registered mail and the notice shall set forth the particular reasons for the denial, suspension, or revocation of the license. Such denial, suspension, or revocation shall become effective 30 days after mailing, unless the applicant or holder of a certificate of approval, within such 30-day period shall meet the requirements of the commissioner, or shall give written notice to the commissioner of its 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 holder of a certificate of approval may appeal from such denial, suspension, or revocation, to any court having jurisdiction of such matters.
The commissioner shall arrange for prompt and fair hearings on all such cases, render written decisions stating conclusions and reasons therefor upon each matter so heard, and is empowered to enter orders of denial, suspension, or revocation consistent with the circumstances in each case.
