N.J. Stat. Ann. § 52:32-26

If the contracting agency determines that the acceptance of the lowest responsible bid on a set-aside contract will result either in the payment of an unreasonable price or in a contract otherwise unacceptable pursuant to the statutes and rules governing purchases by that agency, the contracting agency shall reject all bids and withdraw the designation of the set-aside contract. Bidders shall be notified of the set-aside cancellation, the reasons for the rejection and the State's intent to resolicit bids on an unrestricted basis. The canceled solicitation shall not be counted as a set-aside for the purpose of attaining established set-aside goals. Except in cases of emergency, prior to the final award of the contract, the contracting agency shall provide an opportunity for a hearing on the reasons for the rejection of the set-aside designation. This hearing shall not be considered a contested case under the "Administrative Procedure Act," P.L. 1968, c. 410 (C. 52:14B-1 et seq.).
