(2) Personal service of any document required to be served on the Crown for the purpose of or in connection with any civil proceedings is not requisite; but where the proceedings are by or against the Crown service on the Crown must be effected—
(a)by leaving the document at the office of the person who is in accordance with section 18 of the Crown Proceedings Act 1947, to be served, or of any agent whom that person has nominated for the purpose, but in either case with a member of the staff of that person or agent; or

(3) Any document (other than a claim form) service of which is effected under paragraph 2(a) between 12 noon on a Saturday and midnight on the following day or after 4 in the afternoon on any other weekday shall, for the purpose of computing any period of time after service of that document, be deemed to have been served on the Monday following that Saturday or on the day following that other weekday, as the case may be.
(4) Where by virtue of these rules any document is required to be served on any person but is not required to be served personally and at the time when service is to be effected that person is in default as to acknowledgment of service or has no address for service, the document need not be served on that person unless the Court otherwise directs or any of these rules otherwise provides.
(5) (a) No process shall be served or executed within the jurisdiction on a Sunday except, in case of urgency, with the permission of the Court.
(b)For the purposes of this rule “process” includes a claim form, judgment, application or other notice, order, petition, or warrant.
