Mutually exclusive excise duty schemes bar hybrid reliance on both flat-rate and capacity-based determination under central excise law.

A manufacturer who elects the composite flat-rate scheme under Rule 96ZO(3) cannot thereafter seek redetermination of duty on the basis of annual capacity under Section 3A(4), because the two provisions are mutually exclusive alternative methods of levy and collection. The Bombay HC held that the assessee could not combine the benefits of both schemes, and that the Tribunal erred in remanding the matter without applying the binding Supreme Court position on the incompatibility of the two mechanisms. The remand order was set aside and the matter sent back for fresh consideration under the correct legal position.

Issues: Whether an assessee who opts for the flat-rate scheme under Rule 96ZO(3) of the Central Excise Rules, 1944 can seek redetermination of duty liability on the basis of annual capacity under Section 3A of the Central Excise Act, 1944, and whether the Tribunal was justified in remanding the matter without applying the controlling Supreme Court decisions.

Analysis: Section 3A and Rule 96ZO(3) operate as alternative schemes for levy and collection of excise duty. The flat-rate option under Rule 96ZO(3) is a self-contained composite method, and once that option is exercised, the assessee cannot combine it with the capacity-determination mechanism under Section 3A(4). The Supreme Court had already held that these are alternate procedures and that a manufacturer cannot adopt a hybrid approach by taking benefit of both schemes. The Tribunal, while remanding the matter on the premise that power disruption required fresh capacity redetermination, did not examine the effect of the binding precedent or the legal incompatibility between the two schemes.

Conclusion: The Tribunal's approach was legally erroneous; the matter required reconsideration in the light of the governing law, and the assessee could not claim Section 3A capacity redetermination while remaining under Rule 96ZO(3).

Final Conclusion: The appeal succeeded, the remand order was set aside, and the matter was sent back for fresh consideration in accordance with the correct legal position.

Ratio Decidendi: A manufacturer who has elected to pay duty under the composite flat-rate scheme in Rule 96ZO(3) cannot invoke the capacity-based determination mechanism under Section 3A(4), because the two are mutually exclusive alternative procedures.
