If at any time, it appears to the Authority that the purpose of the order appointing the Administrator has been fulfilled or that, for any reason, it is undesirable that the order of appointment should remain in force, the Authority may cancel the order and thereupon the Administrator shall be divested of the management of the insurance business which shall, unless otherwise directed by the Authority, again vest in the person in whom it was vested immediately prior to the appointment of the Administrator or any other person appointed by the insurer in this behalf.
