Where a minor with a mental illness is found to be dependent or neglected, the public children's services agency in the county of residence has final guardianship authority and responsibility.

(B) In no case shall the guardianship of a person with a mental illness be assigned to the chief medical officer or any staff member of a hospital, board, or provider from which the person is receiving mental health services.
