Modvat credit on exempt clearances must be reversed; suppression supports extended limitation, while later penalty provisions cannot apply retrospectively.

Modvat credit taken on inputs used in exempt clearances must be reversed, so the duty demand was sustained where old rollers were re-rubberised and cleared without duty. Suppression of the material fact that credit-bearing inputs were used in those clearances justified invocation of the extended period of limitation. Penal and interest provisions inserted later were not applied retrospectively to an earlier contravention, so the amended penalty and interest were not exigible for the relevant period. The personal penalty on the Managing Director was deleted because no specific role beyond overall management was established.

Issues: (i) whether the extended period of limitation was invocable on the allegation of suppression of material facts relating to use of modvat credit in re-rubberisation of old rollers cleared without duty, (ii) whether modvat credit taken on inputs used in exempted final products was required to be reversed and the duty demand sustained, and (iii) whether penalty and interest under the amended penal provisions were exigible and whether the penalty on the Managing Director was sustainable.

Issue (i): whether the extended period of limitation was invocable on the allegation of suppression of material facts relating to use of modvat credit in re-rubberisation of old rollers cleared without duty.

Analysis: The activity of re-rubberisation of old rollers was within the department's knowledge, but there was no intimation that inputs on which modvat credit had been availed were being used in the exempted clearances. The records and declarations did not disclose this material fact, and the adjudicating authority recorded a finding that the omission was deliberate and intended to evade duty. On that basis, the longer limitation period was held applicable.

Conclusion: The extended period of limitation was rightly invoked, against the assessee.

Issue (ii): whether modvat credit taken on inputs used in exempted final products was required to be reversed and the duty demand sustained.

Analysis: Credit taken on inputs used in the manufacture or processing of goods not liable to central excise duty cannot be retained. The old and used rollers, after re-rubberisation, were cleared without duty, so the inputs used therein were not eligible for modvat benefit. The decision applied the settled principle that credit becomes inadmissible and must be reversed when the final product is exempt or otherwise not dutiable.

Conclusion: The demand of duty was sustained against the assessee, and the reversal of modvat credit was required.

Issue (iii): whether penalty and interest under the amended penal provisions were exigible and whether the penalty on the Managing Director was sustainable.

Analysis: The period of dispute was substantially prior to the insertion of Rule 57-I(4) and the corresponding interest provision. Penal and interest provisions are applied with reference to the law in force when the contravention occurred, and the amended provisions were not held applicable to the earlier period. The Tribunal therefore declined to interfere with the omission to impose the new statutory penalty and interest. As to the Managing Director, no specific role beyond overall management was established in the adjudication order, and the penalty imposed on him was considered unwarranted in the facts of the case.

Conclusion: Penalty and interest under the amended provisions were not imposable for the relevant period, and the personal penalty on the Managing Director was set aside.

Final Conclusion: The duty demand and the reduced corporate penalty were maintained, the Revenue's challenge to the absence of penalty and interest under the later provisions failed, and the personal penalty on the Managing Director was deleted.

Ratio Decidendi: Modvat credit taken on inputs used in exempted clearances must be reversed, suppression of the material fact of such use justifies the extended limitation period, and penal or interest provisions cannot be applied retrospectively to contraventions committed before those provisions came into force.
