N.J. Stat. § 45:9-42.41
The commissioner, before refusing to grant a license or before suspending, limiting or revoking a license previously granted shall give notice to the applicant or licensee personally, or by mail addressed to him at his last known address, and afford him an opportunity to 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 through an attorney, and to offer evidence pertinent to the subject of the hearing. A duly certified copy of the order of the commissioner issued as a result of such hearing shall be served on the applicant or the licensee by mail personally addressed to him at his last known address, except if such applicant or licensee be a corporation then the order shall be served in the same manner upon any officer or registered agent of the corporation.
If the commissioner shall have reason to believe that a condition exists or has occurred at a laboratory, in violation of the provisions of this act or the rules and regulations promulgated hereunder, which condition poses an imminent threat to the public health, safety or welfare, he may summarily suspend the license of the laboratory without a hearing and may order immediate correction of such violation as a prerequisite of reinstatement of licensure. If a licensee that is subjected to summary suspension shall deny that a violation exists or has occurred, he shall have the right to apply to the commissioner for a hearing. Such hearing shall be held and a decision rendered within 48 hours of receipt of said request. If the commissioner shall rule against the licensee, the licensee shall have the right to apply for injunctive relief against the commissioner's order. Jurisdiction of such injunctive relief shall be in the Superior Court of New Jersey.
