Doctrine of merger under Central Excise law is confined to issues actually decided, leaving untouched portions open to departmental appeal.

Doctrine of merger under the Central Excise Act applies only to the subject-matter actually brought before and decided by the superior forum on merits. Where an assessee's appeal concerns only one part of an order, the remaining part does not merge automatically, and the Revenue may pursue a separate challenge to the untouched portion. The absence of cross-objections does not enlarge the scope of the appeal so as to bar independent statutory action under Section 35E. The doctrine therefore did not prevent a departmental appeal directed on matters outside the assessee's earlier appeal, and merger was confined to the issues actually adjudicated.

Issues: (i) Whether the doctrine of merger barred a revenue appeal under the Central Excise Act, 1944 when the assessee's appeal before the appellate forum had concerned only part of the original order and the revenue's challenge related to another part. (ii) Whether, in the absence of cross-objections, the appellate and revisional powers under the Central Excise Act, 1944 could still be exercised in respect of matters not covered by the assessee's appeal. (iii) Whether the doctrine of merger applied where the earlier appeal had been disposed of on a limited issue and the later departmental appeal was directed under Section 35E of the Central Excise Act, 1944.

Issue (i): Whether the doctrine of merger barred a revenue appeal under the Central Excise Act, 1944 when the assessee's appeal before the appellate forum had concerned only part of the original order and the revenue's challenge related to another part.

Analysis: The doctrine of merger is not of universal application. Its operation depends on the nature of the appellate or revisional jurisdiction and the subject-matter actually brought before the superior forum. Where an appeal is confined to a distinct part of an order, the remaining part does not automatically merge merely because one component has been carried in appeal and decided. The superior forum must have had jurisdiction to deal with the entire controversy for merger to arise.

Conclusion: The doctrine of merger did not bar the revenue appeal; the question was answered against the assessee and in favour of the Revenue.

Issue (ii): Whether, in the absence of cross-objections, the appellate and revisional powers under the Central Excise Act, 1944 could still be exercised in respect of matters not covered by the assessee's appeal.

Analysis: Section 35B(4) enables cross-objections in Tribunal appeals, but the omission to file cross-objections does not enlarge the subject-matter already in appeal so as to attract merger for issues never decided. The appellate forum's power under Section 35C is limited to the order appealed against, while Section 35E confers an independent statutory power on the Board or Commissioner to direct an appeal on points not already in issue. Therefore, the absence of cross-objections does not create a merger of the untouched portion of the order.

Conclusion: The appellate and revisional powers remained available for issues outside the assessee's appeal; the point was decided in favour of the Revenue.

Issue (iii): Whether the doctrine of merger applied where the earlier appeal had been disposed of on a limited issue and the later departmental appeal was directed under Section 35E of the Central Excise Act, 1944.

Analysis: A prior disposal of an appeal confined to one segment of the order does not extinguish the statutory power under Section 35E to challenge a different segment. Merger follows only when the superior forum has finally adjudicated the whole matter capable of being placed before it. Where the earlier appeal did not encompass the revenue's grievance, the later departmental appeal cannot be rejected on merger principles.

Conclusion: The doctrine of merger did not apply, and the departmental appeal was maintainable; the issue was decided in favour of the Revenue.

Final Conclusion: The Court held that merger under the Central Excise Act, 1944 is confined to the matters actually within the scope of the appeal or revision decided on merits, and it does not bar departmental action on untouched parts of the order.

Ratio Decidendi: The doctrine of merger applies only to the subject-matter actually decided by the superior forum on a jurisdiction capable of reversing, modifying, or affirming that subject-matter; it does not extend to portions of the order not brought under effective appellate scrutiny.
