Right of appeal to Appellate Tribunal clarified: time limits, deposit prerequisite for certain appellants, and appellate powers. Appeals to the Appellate Tribunal lie for aggrieved governments, authorities, enterprises or persons against Commission directions, decisions or orders and must be filed within sixty days unless delay is condoned for sufficient cause. Appeals by persons required to pay amounts under a Commission order are subject to a tribunal-directed deposit prerequisite. The Tribunal, after hearing parties, may confirm, modify or set aside orders, must transmit its orders to the Commission and parties, and should dispose of appeals expeditiously, aiming for resolution within six months.
