Cal. Elections Code § 19257

(a) All bonds authorized by this article, when duly sold and delivered as provided herein, constitute valid and legally binding general obligations of the State of California, and the full faith and credit of the state is hereby pledged for the punctual payment of both principal and interest thereof. The bonds issued pursuant to this article shall be repaid within 10 years from the date they are issued. (b) There shall be collected annually, in the same manner and at the same time as other state revenue is collected, a sum of money, in addition to the ordinary revenues of the state, sufficient to pay the principal of, and interest on, the bonds as provided herein. All officers required by law to perform any duty in regard to the collection of state revenues shall collect this additional sum. (c) On the dates on which funds are remitted pursuant to Section 16676 of the Government Code for the payment of the then maturing principal of, and interest on, the bonds in each fiscal year, there shall be returned to the General Fund all of the money in the fund, not in excess of the principal of, and interest on, any bonds then due and payable. If the money so returned on the remittance dates is less than the principal and interest then due and payable, the balance remaining unpaid shall be returned to the General Fund out of the fund as soon as it shall become available, together with interest thereon from the dates of maturity until returned, at the same rate of interest as borne by the bonds, compounded semiannually. This subdivision does not grant any lien on the fund or the moneys therein to holders of any bonds issued under this article. However, this subdivision shall not apply in the case of any debt service that is payable from the proceeds of any refunding bonds. For purposes of this subdivision, “debt service” means the principal (whether due at maturity, by redemption, or acceleration), premium, if any, or interest payable on any date to any series of bonds.
