(a) Filing. Papers required or permitted to be filed in the appellate court shall be filed with the clerk. Filing may be accomplished by first class mail, either registered or unregistered, addressed to the clerk, but filing shall not be timely unless the papers are received by the clerk within the time fixed for filing, except that briefs and appendices shall be docketed on the date of receipt and shall be deemed timely filed if (i) received within the time fixed for filing or (ii) accompanied by an affidavit signed by counsel of record attesting that the day of mailing was within the time fixed for filing. If a motion requests relief which may be granted by a single justice, the justice may permit the motion to be filed with him, in which event he shall note thereon the date of filing and shall thereafter transmit it to the clerk.

(b) Service of All Papers Required. Copies of all papers filed by any party and not required by these rules to be served by the clerk shall, at or before the time of filing be served by a party or person acting for him on all other parties to the appeal or review. Service on a party represented by counsel shall be made on counsel.

(c) Manner of Service. Service may be personal or by first class mail. Personal service includes delivery of the copy to a clerk or other responsible person at the office of counsel. Service by first class mail is complete on mailing.

(d) Proof of Service. Papers presented for filing shall contain an acknowledgment of service by the person served or proof of service in the form of a statement under the penalties of perjury of the date and manner of service and of the name of the person served, signed by the person who made service. Proof of service may appear on or be affixed to the papers filed. The clerk may permit papers to be filed without acknowledgment or proof of service but shall require such acknowledgment or proof to be filed promptly thereafter.
