N.J. Stat. § 27:1B-14
The State does hereby pledge to and covenant and agree with the holders of any bonds, notes or other obligations issued or incurred pursuant to the authorization of the act that the State will not limit or alter the rights or powers hereby vested in the authority in any way that would jeopardize the interest of the holders or inhibit or prevent performance or fulfillment by the authority of the terms of any agreement made with the holders of the bonds, notes or other obligations, or prevent the authority from obtaining sufficient revenues which, together with other available funds, shall be sufficient to meet all expenses of the authority and fulfill the terms of any agreement made with the holders of the bonds, notes or other obligations, together with interest thereon, with interest on any unpaid installments of interest, and all costs and expenses in connection with any action or proceedings by or on behalf of the holders, or from receiving payment of funds of the toll road authorities or other State agencies, as provided in any agreement provided for in the act, until the bonds, notes or other obligations, together with interest thereon, are fully met and discharged or provided for. The standards required to be followed by the State in complying with the foregoing covenant shall be no more or less restrictive than the standards required to be followed by the State under its covenants with the toll road authorities in section 7 of P.L. 1948, c. 454 (C. 27:23-7), section 11 of P.L.1952, c. 16 (C. 27:12B-11) and section 41 of P.L. 1962, c. 10 (C. 27:12C-41). The failure of the State to appropriate moneys for any purpose of the act shall not be deemed or construed to be a violation of this section.
