(4) Any person who, in doing or having done an act mentioned in article 3(a) or (b) or 4(1) under the authority of a licence, contravenes or fails to comply with a condition specified in the licence, is guilty of an offence, unless the condition is one imposed as a result of a variation of the licence made without his consent after he did the act.
(5) A notice under paragraph (2) may be given by post, and shall be deemed to have been given to a person if it is sent to him at his last-known address.
