In a contested case:
Unless the head of the agency or a party requests that the recommended report and decision be filed in writing, the recommended report and decision of the administrative law judge may be filed orally in such appropriate cases as prescribed by the director and if a transcript has been requested pursuant to subsection (e) of section 9 of P.L. 1968, c.410 (C.52:14B-9).
An administrative law judge may file a recommended report and decision in the form of a checklist in such appropriate cases and formats as prescribed by the director after consultation with each State agency.
The head of the agency, upon a review of the record submitted by the administrative law judge, shall adopt, reject or modify the recommended report and decision no later than 45 days after receipt of such recommendations. In reviewing the decision of an administrative law judge, the agency head may reject or modify findings of fact, conclusions of law or interpretations of agency policy in the decision, but shall state clearly the reasons for doing so. The agency head may not reject or modify any findings of fact as to issues of credibility of lay witness testimony unless it is first determined from a review of the record that the findings are arbitrary, capricious or unreasonable or are not supported by sufficient, competent, and credible evidence in the record. In rejecting or modifying any findings of fact, the agency head shall state with particularity the reasons for rejecting the findings and shall make new or modified findings supported by sufficient, competent, and credible evidence in the record. Unless the head of the agency modifies or rejects the report within such period, the decision of the administrative law judge shall be deemed adopted as the final decision of the head of the agency. The recommended report and decision shall be a part of the record in the case. For good cause shown, upon certification by the director and the agency head, the time limits established herein may be subject to a single extension of not more than 45 days. Any additional extension of time shall be subject to, and contingent upon, the unanimous agreement of the parties.
Findings of fact, if set forth in statutory language, shall be accompanied by a concise and explicit statement of the underlying facts supporting the findings. The final decision may incorporate by reference any or all of the recommendations of the administrative law judge. Parties shall be notified either personally or by mail of any decision or order. Upon request a copy of the decision or order shall be delivered or mailed forthwith by registered or certified mail to each party and to his attorney of record.
