Cal. Unemp. Ins. Code § 4001
The purpose of this part is to provide that payment of extended compensation, in accordance with the "Federal-State Extended Unemployment Compensation Act of 1970", as amended by the Omnibus Budget Reconciliation Act of 1981 (Public Law 97-35), shall be made, for any week of unemployment which begins in the individual's eligibility period, to individuals who have exhausted all rights to regular compensation under this division and who have no rights to regular compensation with respect to such week under this division or any other state unemployment compensation law or to compensation under any other federal law. For purposes of this section, an individual shall have exhausted his rights to regular compensation under any state law (A) when no payments of regular compensation can be made under such law because such individual has received all regular compensation available to him based on wage credits for his base period, or (B) when his rights to such compensation have terminated by reason of the expiration of the benefit year with respect to which such rights existed. Except where inconsistent with the provisions of the "Federal-State Extended Unemployment Compensation Act of 1970", as amended by the Omnibus Budget Reconciliation Act of 1981 (Public Law 97-35), the terms and conditions of this division which apply to claims for regular compensation and to the payment thereof shall apply to claims for extended compensation and to the payment thereof under such federal act. This part shall be operative on September 25, 1982, and extended compensation shall be payable as provided by the Federal-State Extended Unemployment Compensation Act of 1970, as amended by the Omnibus Budget Reconciliation Act of 1981 (Public Law 97-35), subject to limitations provided by that act, with respect to weeks of unemployment and extended benefit periods beginning after September 25, 1982. The provisions of this section in effect prior to the amendments by the Omnibus Budget Reconciliation Act of 1981 shall continue to apply to weeks beginning after November 28, 1970, and before September 25, 1982.
