Misstatement in classification declarations justified extended limitation, while penalty was cut because Section 11AC did not apply retrospectively.

A mismatch between the classification list, which declared the goods at the full duty rate, and the actual concessional clearances amounted to misstatement for duty purposes, so the extended period of limitation was rightly invoked against the assessee. Section 11AC of the Central Excise Act, 1944 could not apply to the relevant period because the differential duty related to a time before its introduction, but the penalty was not wholly unsustainable since Rule 173Q was also invoked in the show cause notice. The penalty was therefore reduced and sustained only to the extent supported by the applicable penal rule.

Issues: (i) Whether the extended period of limitation was rightly invoked on the basis of the declarations made in the classification list and the subsequent clearances at concessional rate; (ii) Whether penalty could be sustained when Section 11AC of the Central Excise Act, 1944 was not applicable to the relevant period and, if so, to what extent.

Issue (i): Whether the extended period of limitation was rightly invoked on the basis of the declarations made in the classification list and the subsequent clearances at concessional rate.

Analysis: The goods were not covered by the exemption notification, yet the classification list declared the products at the full duty rate without disclosing any intention to avail the exemption. The classification list was approved on that basis, but the goods were cleared at a lower concessional rate. This divergence between the declaration and the actual clearances constituted a misstatement for duty purposes.

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

Issue (ii): Whether penalty could be sustained when Section 11AC of the Central Excise Act, 1944 was not applicable to the relevant period and, if so, to what extent.

Analysis: Section 11AC could not govern the demand because the differential duty related to a period prior to its introduction. However, the show cause notice had also invoked Rule 173Q of the Central Excise Rules, 1944, so the penalty was not unsustainable merely because the order mentioned Section 11AC. In the circumstances, the penalty warranted reduction.

Conclusion: Penalty under Section 11AC was inapplicable for the relevant period, but a reduced penalty under Rule 173Q was sustained, partly in favour of the assessee.

Final Conclusion: The duty demand survived on limitation, while the penalty was substantially curtailed because the penal provision applied by the order did not govern the relevant period.

Ratio Decidendi: A clear mismatch between the classification declaration and the actual concessional clearances amounts to misstatement justifying the extended limitation period, but a penalty provision cannot be applied retrospectively to a prior period when a different penal rule alone supports the levy.
