California Code, Welfare and Institutions Code - WIC § 5270.70

(a) If, after 15 days of the 30-day period of intensive treatment pursuant to this article, but at least 7 days before expiration of the 30 days, the professional staff of the agency or facility treating the person finds that the person remains gravely disabled as a result of a mental disorder or impairment by chronic alcoholism and the person remains unwilling or unable to accept treatment voluntarily, the professional person in charge of the facility providing intensive treatment to the person may file a petition in the superior court for the county in which the facility providing intensive treatment is located, seeking approval for up to an additional 30 days of intensive treatment. The court shall immediately appoint the public defender or other attorney to represent the person in the hearing under this section, if that person does not already have counsel to represent them in the proceedings.

(b) Reasonable attempts shall be made by the mental health facility to notify family members or any other person designated by the patient of the time and place of the judicial review, unless the patient requests that this information not be provided. The patient shall be advised by the facility that is treating the patient that the patient has the right to request that this information not be provided.

(d) A finding under this section shall not be admissible in evidence in any civil proceeding without the consent of the person who was the subject of the finding.

(e) In no event may a person be held beyond the original 30-day period of intensive treatment unless a court has determined that an additional period of up to 30 days of treatment is required, regardless of whether or not the court hearing has been set.
