Summons form and service: prescribed format with affidavit support and specified advance service periods before hearing. A summons must follow Form No. 17 and, unless exempted, be supported by an affidavit. It must be served on every person against whom an order is sought and on any other person the Member directs, by personal delivery, prepaid registered or speed post, empanelled courier agency, or on the party's representative, advocate or pleader, or in such other manner as the Member may direct. Interlocutory summonses require a shorter advance service period before the hearing, while non interlocutory summonses require a longer advance service period, unless otherwise provided by these rules or ordered by the Tribunal.
