(2) A licence shall not be granted under paragraph (1) above unless the Minister is satisfied that the premises to which it relates are under the supervision of a veterinary surgeon or (in the case of research premises only) a registered medical practitioner who has been authorised in writing by him to act in that behalf, and any such authorisation may be issued for such period as may be specified therein, and given subject to such conditions as may be so specified.
(3) A licence granted under paragraph (1) above shall remain in force for such period as may be specified therein, and shall be granted subject to such terms and conditions as may be so specified.
(4) Nothing in the foregoing provisions of this Article shall be construed as precluding the Minister at any time from withdrawing an authorisation given or revoking a licence granted thereunder, or from varying the terms or conditions subject to which it was given or granted, but without prejudice to anything lawfully done pursuant thereto before such withdrawal, revocation or variation takes effect.
