Cal. Rev. & Tax. Code § 41142

Notwithstanding any other provision of this article, if the Legislature fails to appropriate an amount sufficient to pay bills submitted to the Office of Emergency Services by service suppliers or communications equipment companies for the installation and ongoing communications services supplied local agencies in connection with the “911” emergency telephone number system, and to pay claims of local agencies which, prior to the effective date of this part, paid amounts to service suppliers or communications equipment companies for the installation and ongoing expenses in connection with the “911” emergency telephone number system, the obligation of service suppliers and local agencies to provide “911” emergency telephone service shall terminate and service shall not again be required until the Legislature has appropriated an amount sufficient to pay those bills or claims. This part shall not preclude local agencies from purchasing or acquiring any communication equipment from companies other than the telephone service suppliers.
