Cal. WIC § 1756

Notwithstanding any other law, if, in the opinion of the Chief Deputy Secretary for the Division of Juvenile Justice, the rehabilitation of a person with a mental health disorder or a developmental disability who is confined in a state correctional school may be expedited by treatment at one of the state hospitals under the jurisdiction of the State Department of State Hospitals or the State Department of Developmental Services, the Chief Deputy Secretary for the Division of Juvenile Justice shall certify that fact to the director of the appropriate department who may authorize receipt of the person at one of the hospitals for care and treatment. Upon notification from the director that the person will no longer benefit from further care and treatment in the state hospital, the Chief Deputy Secretary for the Division of Juvenile Justice shall immediately send for, take, and receive the person back into a state correctional school. A person placed in a state hospital under this section who is committed to the authority shall be released from the hospital upon termination of his or her commitment unless a petition for detention of that person is filed under the provisions of Part 1 (commencing with Section 5000) of Division 5.
