N.J. Stat. § 5:3-58
A rider who fails to give the report required by section 3 of this act within 90 days from the time of the accident or incident may be permitted to give the report at any time within one year after the accident or incident at the discretion of a judge of the Superior Court if the operator is not substantially prejudiced thereby. The inability of the amusement park operator to locate and bring within the jurisdiction of the court needed witnesses for his defense shall be considered by the court in determining whether the operator has been substantially prejudiced by the delay. Application to the court for permission to give a late report shall be made upon motion based on affidavits showing sufficient reason for the rider's failure to give the report within 90 days from the time of the accident or incident.
