Cal. Gov. Code § 16773

Whenever any payment of principal of any bonds shall become due, either upon the maturity of any of the bonds or upon the redemption thereof prior to maturity, and whenever any interest on any of the bonds shall fall due, warrants shall be drawn against the appropriation made by the bond act from the General Fund by the Controller in favor of the Treasurer, or state fiscal agents, or other duly authorized agents, pursuant to claims filed with the Controller by the Treasurer, in the amounts so falling due. For any payments of debt service, as defined in subdivision (c) of Section 998.404 of the Military and Veterans Code, with respect to any bonds issued pursuant to a veterans’ farm and home purchase bond act adopted pursuant to Chapter 6 (commencing with Section 980) of Division 4 of the Military and Veterans Code, the Controller shall first draw warrants against the appropriation from the Veterans’ Bonds Payment Fund in Section 988.6 of the Military and Veterans Code, and, to the extent moneys in that fund are insufficient to pay the amount of debt service then due, shall draw warrants against the appropriation made by the bond act from the General Fund for payment of any remaining amount then due.
