A person who has been committed by the probate court before January 1, 1998, or the family division of circuit court on or after January 1, 1998 or a court of general criminal jurisdiction to an institution or agency of the state which is authorized to receive juveniles under the direction of the former department of mental health, the department of community health, the department of corrections, the former department of social services, or the family independence agency for the purpose of treatment, or training, or both, may be transferred from that institution to any other institution or agency of the state, if it appears to the satisfaction of the superintendent of the institution to which the person has been committed that the person will substantially benefit from the care and training in the other institution or facility and that the interests of the person and of the state will be best served thereby.

     Such a transfer may be made only upon a written request by the said superintendent and the approval of the committing judge and of the governing bodies of the institution or agency of the state from which and to which such transfer shall be made, after notice to the parents of the juvenile or to his legal guardian, if he is under guardianship.

     Any institution to which any such person is transferred, as in this act provided, shall and is hereby authorized to receive, train, and otherwise care for such person in the same manner as other persons committed to that institution.

     While in such institution, he shall be under the laws and rules appertaining thereto, except that his parole and discharge shall continue to be governed by the laws and rules appertaining to the institution or agency to which he was originally committed.

     The terms of detention or confinement of a person transferred in accordance with the provisions of this act shall not be extended or increased by reason of any such transfer.

     Whenever, for any reason, it shall be found that it is not in the best interests of any person to remain in an institution to which he shall have been transferred as provided for and permitted by this act, and the governing body of such institution or agency so requests, such person shall, after satisfactory arrangements therefor have been completed, be returned to the institution or agency from which he was transferred.

     Whenever any person is transferred under the provisions of this act, he shall be accompanied by all mittimuses, processes, orders, supplemental orders, a copy of his medical report, and a written statement covering the history and progress of the person, so far as the same are available or can be ascertained.

     All expenses incidental to a transfer under this act shall be borne by the department or agency from which the transfer is made.
