Doctrine of merger bars a later departmental challenge once the same adjudication order has been finally decided in appeal.

The doctrine of merger applied where an assessee's appeal had already brought the adjudication order before the Tribunal for final determination, because the order merged into the appellate order on the same subject-matter. On that footing, the Revenue could not later invoke Section 35E of the Central Excise Act, 1944 to challenge the same merged order. The Tribunal read Sections 35B and 35E harmoniously and held that a subsequent departmental proceeding cannot reopen an order that has already been finally decided in appeal. The Revenue's challenge was therefore not maintainable.

Issues: Whether the Revenue's appeal under Section 35E of the Central Excise Act, 1944 was maintainable after the assessee's earlier appeal had already resulted in the Tribunal's final order on the same adjudication order, so as to attract the doctrine of merger.

Analysis: The Tribunal held that the applicability of merger depends on the nature of the superior forum's jurisdiction and the subject-matter capable of being examined before it. Under Section 35B of the Central Excise Act, 1944, an appeal and cross-objection mechanism existed, and Section 35E of the Central Excise Act, 1944 permitted the Board to direct an application to the Tribunal within the prescribed period. Reading these provisions harmoniously, the Tribunal concluded that where the assessee had already carried the adjudication order in appeal and the Tribunal had rendered its final decision, the adjudication order stood merged in the appellate order. The Revenue could not thereafter invoke Section 35E to reopen the same order.

Conclusion: The Revenue's appeal was held to be not maintainable and the merger doctrine was applied against the Revenue.

Ratio Decidendi: Where a statutory appeal by one party has already brought the adjudication order before the Tribunal for final determination, the order merges in the appellate order and a later proceeding under Section 35E cannot be used to challenge the same merged order.
