Appellate Tribunal powers to confirm, modify, annul or remit orders are constrained by rectification rules and procedural safeguards. The Appellate Tribunal may confirm, modify, annul or remit orders for fresh adjudication after hearing parties, grant limited adjournments (no more than three per party), and within six months amend orders to rectify mistakes apparent from the record; amendments increasing another party's liability require notice and an opportunity to be heard. Appeals should, where possible, be decided within three years, copies of orders must be sent to the Commissioner and the other party, and orders are final save as otherwise provided by statute.
