Existing law, the Lanterman-Petris-Short Act, provides for the involuntary commitment and treatment of persons with specified mental disorders. Under the act, when a person, as a result of a mental health disorder, is a danger to others or to themselves, or is gravely disabled, the person may, upon probable cause, be taken into custody and placed in a facility designated by the county and approved by the State Department of Health Care Services for up to 72 hours for evaluation and treatment.
