California Code, Welfare and Institutions Code - WIC § 16502.5

(a) Notwithstanding any other provision of law, a county board of supervisors may receive and review any records in the custody of the juvenile court or any other involved county agencies relating to a child who has died and who had previously come to the attention of, or was under the supervision of, the county child welfare agency.

(b) The board may only receive and review the information in closed session. A board of supervisors in a county with a foster care population of more than 10,000 may take formal action to permit individual board members' offices to receive and review the information for the purpose of determining which cases should be brought to the attention of the full board in closed session. The information or records obtained shall be maintained in a manner that ensures the maximum protection of privacy and confidentiality rights.

(c) The board or its members and staff may not disclose or release any information obtained pursuant to subdivision (a), unless otherwise permitted by state law, and shall be bound by all state and federal confidentiality laws.
