(5) A copy of a report by an expert witness shall be served (a) by filing it in the Registry in which the notice of appeal was filed or to which it was mailed or by sending the report by mail or fax to that Registry, and (b) on every other party to an appeal by personal service or by sending the report to that party by mail or fax and, if a copy of the report is served by fax, the date of service is the date of the transmission of the fax, or if it is served by mail, the date of service is the date stamped on the envelope at the post office and, if there is more than one such date, the date of service shall be deemed to be the earliest date.
