Cal. GOV § 6596

The State of California does hereby pledge to, and agrees with, the holders of any bonds issued under this article, and with those parties who may enter into contracts with the authority pursuant to this article, that the state will not limit or alter the rights hereby vested in the authority to finance any public capital improvement and to fulfill the terms of any loan agreement, lease, or other contract with the authority pursuant to this part, or in any way impair the rights or remedies of the bonds or of the parties until those bonds, together with the interest thereon, are fully met and discharged and those contracts are fully performed on the part of the authority. However, nothing in this section precludes this limitation or alteration if and when adequate provision has been made by law for the protection of the holders of those bonds of the authority or those entering into those contracts with the authority.
