New Jersey Statutes Title 27. Highways 27 § 14-13

Before any work is done under the contract, the contract, together with the contractor's bond, shall be exhibited to the commissioner for his approval in writing thereon, but the commissioner may, if he deems it to the best interests of the county, reject the contract, in which case he shall cause the word “rejected” to be placed thereon. From the time of such rejection the bond required to accompany the contract shall be null and void, but such rejection shall not prevent the board from readvertising for bids and proceeding thenceforth under the provisions of this article if such action is taken within four months after such rejection. Otherwise the approval required by section 27:14-3 of this title shall be null and void.
