Cal. Welf. and Inst. Code § 5585.20
This part shall apply only to the initial 72 hours of mental health evaluation and treatment provided to a minor. Notwithstanding the provisions of the Lanterman-Petris-Short Act (Part 1 (commencing with Section 5000)), unless the context otherwise requires, the definitions and procedures contained in this part shall, for the initial 72 hours of evaluation and treatment, govern the construction of state law governing the civil commitment of minors for involuntary treatment. To the extent that this part conflicts with any other law, it is the intent of the Legislature that this part shall apply. Evaluation and treatment of a minor beyond the initial 72 hours shall be pursuant to the Lanterman-Petris-Short Act (Part 1 (commencing with Section 5000)).
