s 21 Review, discharge and transfer of inmates
21.—(1) The Review Committee of an approved centre must keep the case of every inmate under review and must, as often as practicable, consider whether he or she should be discharged. (2) Despite any order made under section 17, the Director or the Review Committee of an approved centre may at any time by order in writing —(a) discharge any inmate; or (b) transfer any inmate from one approved centre to another approved centre. (3) The officer-in-charge of an approved centre may enter into an arrangement with the officer-in-charge of another approved centre for the transfer of any inmate to that other approved centre and may, subject to any direction given by the Director or the Review Committee, carry out any transfer in accordance with that arrangement, except that the whole period of detention for which the inmate was admitted to such approved centre must not be increased by the transfer. (4) On proof to his or her satisfaction that the presence at any place of an inmate is required in the interests of justice, or for the purpose of any inquiry, or in the public interest or in the interest of the inmate, the officer-in-charge of the relevant approved centre may order that the inmate be taken to that place.
