Right of appeal requires prescribed pre-deposit and procedural compliance before challenging adjudicating authority orders. An aggrieved person may appeal to the prescribed Appellate Authority within the statutory period, with appeals required in prescribed form and verification and subject to payment of the admitted amount and a prescribed pre-deposit; the Commissioner may call records and direct applications to the Appellate Authority which are treated as appeals. The Appellate Authority must hear parties, may grant limited adjournments and admit additional grounds for non-wilful omissions, and after inquiry may confirm, modify or annul the order by a reasoned written decision; payment of the pre-deposit stays recovery of the balance.
