Retrospective excise penalty barred under new provisions, but independent rule-based penalty and personal liability were sustained.

Sections 11AC and 11AB of the Central Excise Act could not be applied to conduct relating to a period before those provisions came into force on 28.09.1996, so retrospective penalty and interest under those sections were impermissible. However, penalty could still be sustained under Rule 173Q of the Central Excise Rules because that rule independently authorised penalty for the same conduct, and the amount imposed was supported by that framework. The personal penalty on the Managing Director under Rule 209A was also restored on the basis of participation in duty evasion, and prior leniency in another matter did not prevent fresh penalty for a subsequent offence.

Issues: (i) Whether penalty under Section 11AC of the Central Excise Act, 1944 could be imposed for a period prior to its insertion; (ii) whether interest under Section 11AB of the Central Excise Act, 1944 could be levied for a period prior to its insertion; (iii) whether penalty could still be sustained under Rule 173Q of the Central Excise Rules, 1944 despite inapplicability of Sections 11AC and 11AB; (iv) whether the personal penalty on the Managing Director under Rule 209A of the Central Excise Rules, 1944 was rightly restored.

Issue (i): Whether penalty under Section 11AC of the Central Excise Act, 1944 could be imposed for a period prior to its insertion.

Analysis: Section 11AC came into force only on 28.09.1996, whereas the proceedings related to an earlier period. A penalty provision cannot be retrospectively applied to conduct completed before its commencement.

Conclusion: The issue was answered in favour of the assessee and against the Revenue.

Issue (ii): Whether interest under Section 11AB of the Central Excise Act, 1944 could be levied for a period prior to its insertion.

Analysis: Section 11AB also became operative only from 28.09.1996. For a prior period, interest could not be fastened under that provision.

Conclusion: The issue was answered in favour of the assessee and against the Department.

Issue (iii): Whether penalty could still be sustained under Rule 173Q of the Central Excise Rules, 1944 despite inapplicability of Sections 11AC and 11AB.

Analysis: Rule 173Q independently empowered imposition of penalty up to three times the value of the goods. The penalty imposed was only equivalent to duty and was supported by the rule, even though Sections 11AC and 11AB were unavailable.

Conclusion: The issue was answered in favour of the Revenue and against the assessee.

Issue (iv): Whether the personal penalty on the Managing Director under Rule 209A of the Central Excise Rules, 1944 was rightly restored.

Analysis: The record showed participation in evasion of duty, and the Tribunal had no valid basis to set aside the penalty merely because a different penalty had been imposed in another matter. Prior leniency in another case did not bar a fresh penalty for a subsequent offence.

Conclusion: The issue was answered in favour of the Department and against the Managing Director.

Final Conclusion: The reference was disposed of by upholding the penalty under the pre-existing rule and restoring the personal penalty, while rejecting retrospective application of Sections 11AC and 11AB.

Ratio Decidendi: A penalty or interest provision cannot be applied retrospectively to a prior period merely because the demand was adjudicated later, but an independent penalty may still be sustained under an operative rule that expressly authorises it for the same conduct.
