N.J. Stat. Ann. § 40:55D-75

An appeal to the board of adjustment shall stay all proceedings in furtherance of the action in respect to which the decision appealed from was made unless the officer from whose action the appeal is taken certifies to the board of adjustment, after the notice of appeal shall have been filed with him, that by reason of facts stated in the certificate a stay would, in his opinion, cause imminent peril to life or property. In such case, proceedings shall not be stayed other than by an order of the Superior Court upon notice to the officer from whom the appeal is taken and on due cause shown.
