Inviolability of premises
6.—(1) The premises of the Organisation have the like inviolability as, in accordance with the 1961 Convention Articles(1), is accorded in respect of the premises of a diplomatic mission.
(2) Any person having the authority to enter any place under any legal provision shall not exercise that authority in respect of the premises of the Organisation unless permission to do so has been given by the Secretary General or by another designated person acting on behalf of the Secretary General.
