Tribunal orders: time limited power to amend apparent-record mistakes and mandatory service of orders to parties. The Tribunal may, after giving parties a reasonable opportunity of being heard, pass orders it deems fit and must send a copy of every order to all parties. It has a time limited power to amend orders to rectify mistakes apparent from the record and shall make such amendment if the mistake is brought to its notice by a party, but this amendment power does not apply to orders under appeal.
