CA Pub Util Code Section 130552

The State of California does hereby pledge to, and agree with, the holders of any bonds issued under this chapter and with those parties who may enter into contracts with the commission pursuant to this chapter that the state will not limit or alter the rights hereby vested in the commission until the bonds, together with the interest thereon, are fully met and discharged and the contracts are fully performed on the part of the commission. However, nothing in this section precludes that limitation or alteration if and when adequate provision has been made by law for the protection of the bondholder or those entering into contracts with the commission. The commission, as agent for the state for this purpose only, may include this pledge and undertaking for the state in issuing its bonds and entering into contracts.
