California Code, Welfare and Institutions Code - WIC § 6002.20

(a) If the minor requests an independent clinical review of his or her continued inpatient treatment, the patients' rights advocate shall be notified of the request, as soon as practical, but no later than one working day. The role of the advocate shall be to provide information and assistance to the minor relating to the minor's right to obtain an independent clinical review to determine the appropriateness of placement within the facility. The advocate shall conduct his or her activities in a manner least disruptive to patient care in the facility. Nothing in this section shall be construed to limit, or expand, rights and responsibilities the advocate has pursuant to other provisions of law.

(b) An independent review may be requested up to 10 days after admission. At any time the minor may rescind his or her request for a review.
