Mutually exclusive excise assessment options under Rule 96ZO prevent a later switch to Section 3A(4) relief.

Under Section 3A of the Central Excise Act, duty for pending matters was to be assessed for the relevant whole financial year on the basis accepted by the manufacturers. Rule 96ZO(3) was treated as an optional, capacity-based scheme operating as full and final discharge of duty liability, but only on the express condition that the manufacturer would not claim the benefit of Section 3A(4). Once that option was exercised, the manufacturer could not switch to actual-production assessment to obtain a lower liability. The mutually exclusive nature of the two modes was therefore affirmed.

Issues: (i) Whether duty under Section 3A of the Central Excise Act, 1944 could be assessed for the whole financial year on the basis of actual production in pending matters; (ii) Whether Rule 96ZO barred a manufacturer who had opted for payment under sub-rule (3) from claiming the benefit of Section 3A(4).

Issue (i): Whether duty under Section 3A of the Central Excise Act, 1944 could be assessed for the whole financial year on the basis of actual production in pending matters.

Analysis: The manufacturers gave up their challenge to the validity of Section 3A and accepted that assessment could be made for the whole financial year in respect of matters not yet closed and still pending before the authorities. The dispute on this point therefore stood resolved on the basis recorded in the order.

Conclusion: Duty under Section 3A was to be assessed for the relevant whole financial year in pending matters.

Issue (ii): Whether Rule 96ZO barred a manufacturer who had opted for payment under sub-rule (3) from claiming the benefit of Section 3A(4).

Analysis: Rule 96ZO(3) provided an optional scheme under which payment based on furnace capacity operated as full and final discharge of duty liability, subject to the express condition that the manufacturer would not avail the benefit under Section 3A(4). The Court treated the two procedures as alternative methods, and held that a manufacturer could not first choose the capacity-based scheme and later switch to actual-production assessment to secure a lower liability.

Conclusion: A manufacturer who opted for Rule 96ZO(3) could not claim the benefit of Section 3A(4).

Final Conclusion: The challenge to the capacity-based excise scheme was rejected in substance, and the optional procedure under Rule 96ZO(3) was held to exclude a later claim under Section 3A(4) once the option was exercised.

Ratio Decidendi: Where a fiscal scheme offers alternative modes of assessment or payment, the assessee must abide by the mode consciously chosen and cannot later invoke the other mode to reduce liability when the governing rule makes the option mutually exclusive.
