N.J. Stat. § 40A:7-22
If the report is not made and filed within the time fixed in N.J.S. 40A:7-21, the municipality to which the territory is annexed shall forthwith apply to the Superior Court assignment judge of the county in which the municipality is located, for an order appointing three commissioners to take the place of and perform the work of the committees, who shall perform the work and make their report within 30 days from the date of their appointment, unless otherwise ordered by the judge.
The report of the commissioners, or a majority of them, shall be made in duplicate and filed with the clerk of each of the municipalities, and shall have the same force and effect, and be as binding as if a report had been made and filed by the committees.
The commissioners shall be paid for their services by the municipality applying for their appointment and by the municipality of which the territory formerly was a part.
The judge shall, upon application of the commissioners, and after they have filed their report, fix the amount to be paid to each commissioner, and the part thereof to be paid by each municipality, and for which respective amounts said municipalities shall be liable.
