N.J. Stat. § 32:1-35.55
The two states covenant and agree with each other and with the holders of any affected bonds, as hereinafter defined, that so long as any of such bonds remain outstanding and unpaid and the holders thereof shall not have given their consent as provided in their contract with the port authority, the two states will not diminish or impair the power of the port authority (or any subsidiary corporation incorporated for any of the purposes of this act) to establish, levy and collect rentals, tolls, fares, fees or other charges in connection with any facility constituting a portion of the port development project or any other facility owned or operated by the port authority of which the revenues have been or shall be pledged in whole or in part as security for such bonds (directly or indirectly, or through the medium of the general reserve fund or otherwise), or to determine the quantity, quality, frequency or nature of the service provided in connection with each such facility.
"Affected bonds" as used in this section shall mean bonds of the port authority issued or incurred by it from time to time for any of the purposes of this act or bonds as security for which there may or shall be pledged, in whole or in part, the general reserve fund or any reserve fund established by or pursuant to contract between the port authority and the holders of such bonds, or the revenues of the world trade center, Hudson tubes, Hudson tubes extensions or any other facility owned or operated by the port authority any surplus revenues of which would be payable into the general reserve fund, or bonds both so issued or incurred and so secured.
