Retrospective penalty and interest on excise duty default barred where the governing rule was omitted before notice.

Where the rule authorising monthly duty payment, penalty and interest had been omitted before the show-cause notice was issued, and no saving clause preserved pending action, penalty could not be sustained despite retrospective protection under section 38A of the Central Excise Act and revalidation under section 132 of the Finance Act, 2001. The Explanation to section 132 protected persons from penal consequences where the act or omission was no longer punishable after the provision came into force, so the penalty demand failed. Interest on delayed duty payment, treated as a quasi-punitive liability arising on default, was also not recoverable retrospectively on the same reasoning, and the interest demand likewise failed.

Issues: (i) whether penalty could be sustained for default in payment of excise duty when the rule under which action was taken had been omitted and the show-cause notice was issued thereafter; (ii) whether interest on delayed payment of duty could be recovered in the light of the omission of the rule and the subsequent statutory revalidation.

Issue (i): whether penalty could be sustained for default in payment of excise duty when the rule under which action was taken had been omitted and the show-cause notice was issued thereafter.

Analysis: The omitted rule had earlier provided for monthly payment of duty as well as for interest and penalty on defaulters. The show-cause notice was issued after the omission of the rule and there was no saving clause preserving pending action under that rule. Section 38A of the Central Excise Act, 1944, gave retrospective protection to departmental actions taken under amended or repealed provisions, and Section 132 of the Finance Act, 2001 revalidated such actions, but the Explanation to Section 132 protected persons from penal consequences where the act or omission was not punishable after the section came into force.

Conclusion: The penalties were not sustainable and were set aside in favour of the assessee.

Issue (ii): whether interest on delayed payment of duty could be recovered in the light of the omission of the rule and the subsequent statutory revalidation.

Analysis: Interest on delayed duty payment was treated as a liability arising on default and in the nature of a quasi-punishment. On that basis, the protection flowing from the Explanation to Section 132 of the Finance Act, 2001 was held to extend to interest as well, and retrospective recovery of interest was not permissible.

Conclusion: The demand of interest was not sustainable and was set aside in favour of the assessee.

Final Conclusion: The assessee succeeded on both the penalty and interest demands, and the impugned order was overturned in full.

Ratio Decidendi: Where the statutory basis for penal action has been omitted without a saving clause, and the later validating provision protects only actions not punishable under the new regime, penalty and interest of a quasi-punitive character cannot be retrospectively recovered.
