N.J. Stat. § 26:1A-23
The commissioner shall call to the attention of any local board of health, by such notice as he may deem reasonable, any failure on its part to enforce the laws of the State or the provisions of the State Sanitary Code and afford such local board an opportunity to explain its failure. The determination of the commissioner as to what is a reasonable notice shall be conclusive. If, after a hearing, it is found that no good reason exists for the failure of the local board of health to enforce the law or the provisions of the State Sanitary Code, the commissioner shall issue an order directing it to do so.
If the local board fails to comply with such order within the time specified, or, if none is specified, within a reasonable time, the commissioner shall immediately take such action as may be necessary to perform the acts specified in the order.
In all legal proceedings the order of the commissioner shall be prima facie evidence of compliance with the provisions of this section, and conclusive evidence of the violation recited in the order.
