California Code, Unemployment Insurance Code - UIC § 1338

If the appeals board issues a decision allowing benefits the benefits shall be paid regardless of any further action taken by the director, the appeals board, or any other administrative agency, and regardless of any appeal or mandamus, or other proceeding in the courts. If the decision of the appeals board is finally reversed or set aside, no employer's account shall be charged with the benefits paid pursuant to this section, except as provided in Section 1026, or if the department determines pursuant to Section 1026.1 that the employer's reserve account should not be credited.
