Welf. & Inst. Code, § 10960

(a) Within 30 days after receiving the decision of the director, which is the proposed decision of an administrative law judge adopted by the director as final, a final decision rendered by an administrative law judge, or a decision issued by the director himself or herself, the affected county or applicant or recipient may file a request with the director for a rehearing. The director shall immediately serve a copy of the request on the other party to the hearing and that other party may within five days of the service file with the director a written statement supporting or objecting to the request. The director shall grant or deny the request no later than the 35th working day after the request is made to ensure the prompt and efficient administration of the hearing process. If the director grants the request, the rehearing shall be conducted in the same manner and subject to the same time limits as the original hearing.

(b) The grounds for requesting a rehearing are as follows:

(1) The adopted decision is inconsistent with the law.

(2) The adopted decision is not supported by the evidence in the record.

(3) The adopted decision is not supported by the findings.

(4) The adopted decision does not address all of the claims or issues raised by the parties.

(5) The adopted decision does not address all of the claims or issues supported by the record or evidence.

(6) The adopted decision does not set forth sufficient information to determine the basis for its legal conclusion.

(7) Newly discovered evidence, that was not in custody or available to the party requesting rehearing at the time of the hearing, is now available and the new evidence, had it been introduced, could have changed the hearing decision.

(8) For any other reason necessary to prevent the abuse of discretion or an error of law, or for any other reason consistent with Section 1094.5 of the Code of Civil Procedure.

(c) The notice granting or denying the rehearing request shall explain the reasons and legal basis for granting or denying the request for rehearing.

(d) The decision of the director, which is the proposed decision of an administrative law judge adopted by the director as final, a final decision rendered by an administrative law judge, or a decision issued by the director himself or herself, remains final pending a request for a rehearing. Only after a rehearing is granted is the decision no longer the final decision in the case.

(e) Notwithstanding any other provision of law, a rehearing request or decision shall not be a prerequisite to filing an action under Section 10962.

(f) (1) Notwithstanding subdivision (a), an applicant or recipient otherwise may be entitled to a rehearing pursuant to this chapter if he or she files a request more than 30 days after the decision of the director is issued, or if he or she did not receive a copy of the decision of the director, or if there is good cause for filing beyond the 30-day period. The director may determine whether good cause exists.

(2) For purposes of this subdivision, “good cause” means a substantial and compelling reason beyond the party’s control, considering the length of the delay, the diligence of the party making the request, and the potential prejudice to the other party. The inability of a person to understand an adequate and language-compliant notice, in and of itself, shall not constitute good cause. The department shall not grant a request for a rehearing for good cause if the request is filed more than 180 days after the order or action complained of.

(3) This section shall not preclude the application of the principles of equity jurisdiction as otherwise provided by law.

(g) Notwithstanding the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code), the department shall implement this section through an all-county information notice no later than January 1, 2008. The department may also provide further instructions through training notes.
