New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 84A-21.6

An interlocutory appeal taken from a decision to uphold or quash a subpoena shall act as a stay of all penalties which may have been imposed for failure to comply with the court's order. The record on appeal shall be kept under seal until such time as appeals are exhausted. In the event that all material or any part thereof is found to be privileged, the record as to that privileged material shall remain permanently sealed. Any subpoenaed materials which shall, upon exhaustion and determination of such appeals, be found to be privileged, shall be returned to the party claiming the privilege.
