Compounding levy choice under excise law is binding; assessees cannot later switch to actual production assessment.

Under the compounding levy scheme for induction furnace units, Section 3A of the Central Excise Act, 1944 read with Rule 96-ZO provides alternative and mutually exclusive modes for duty determination. An assessee who elects the capacity-based compounding levy cannot later switch to actual production-based assessment for the same financial year or seek year-end redetermination of duty liability. The rule-making framework does not permit repeated or opportunistic changes in the chosen method. Duty, interest and penalty were therefore maintained on the basis of the elected compounding levy option.

Issues: Whether, under the compounding levy scheme for induction furnace units, the assessee could switch from the capacity-based option under Rule 96-ZO(1) to actual production-based assessment under Section 3A of the Central Excise Act, 1944 and claim redetermination of duty liability at the end of the financial year.

Analysis: The statutory scheme of Section 3A of the Central Excise Act, 1944 read with Rule 96-ZO of the Central Excise Rules, 1944 provides alternative methods for determination and discharge of duty liability. The scheme permits an assessee to opt for one prescribed method, but does not contemplate repeated or whimsical switching between the capacity-based compounding levy and actual production-based assessment. Once the assessee has exercised the option under the compounding levy route, the benefit of the alternative method is not available. The rule-making provision cannot enlarge the legislative mandate by creating a right to change the elected method during the relevant financial year.

Conclusion: The assessee had no right to shift from the compounding levy option to actual production-based assessment for redetermination of duty liability at year-end. The demand, interest and penalty were upheld.

Final Conclusion: The appeal failed because the selected duty-assessment option under the compounding levy scheme was binding and could not be substituted by a later claim for assessment on actual production basis.

Ratio Decidendi: Where the statute provides mutually exclusive modes for discharge of excise duty under the compounding levy scheme, an assessee who has opted for one mode cannot later claim the benefit of the other mode for the same financial year.
