(a) Subject to the provisions of subsections (b) and (c), persons in involuntary treatment pursuant to this act may be transferred to any approved facility.

(b) In the absence of an emergency, persons committed pursuant to section 304(g)(2)¹ may not be transferred unless written notice is given to the committing judge and the district attorney in the committing county and no objection is noted from either within 20 days of receipt of said notice. If the court or the district attorney objects to said transfer, a hearing shall be held by the court within 20 days to review the commitment order. A decision shall be rendered within 48 hours after the close of evidence.

(c) Whenever such transfer will constitute a greater restraint, it shall not take place unless, upon hearing, a judge or mental health review officer finds it to be necessary and appropriate.
