Retrospective exemption clarification for reprocessed plastic materials defeats duty demand, penalty and interest cannot survive independently.

An amended exemption entry in Notification No. 15/94-CE for reprocessed plastic materials was treated as clarificatory and retrospective because it merely supplied an omission in a consistent exemption scheme reflected in predecessor and successor notifications. The duty demand for the disputed period therefore could not be sustained. As no duty liability survived, penalty under Section 11AC and interest under Section 11AB also could not stand independently, and the ancillary liabilities were set aside.

Issues: (i) Whether the amended entry in Notification No. 15/94-CE granting nil rate of duty to reprocessed plastic materials was clarificatory and retrospective so as to cover the disputed period; (ii) whether penalty under Section 11AC and interest under Section 11AB could be sustained when the duty demand itself failed.

Issue (i): Whether the amended entry in Notification No. 15/94-CE granting nil rate of duty to reprocessed plastic materials was clarificatory and retrospective so as to cover the disputed period.

Analysis: A similar exemption existed in predecessor notifications and continued in successor notifications. The omission in the relevant notification was for a short intervening period, and the later insertion of the entry was treated as supplying an omitted clarification rather than introducing a new benefit. On that basis, the amendment was held to reflect the intended exemption regime for the disputed period.

Conclusion: The amended entry was held to be clarificatory and retrospective, and the duty demand for the disputed period was not sustainable.

Issue (ii): Whether penalty under Section 11AC and interest under Section 11AB could be sustained when the duty demand itself failed.

Analysis: The demand having been negatived, no duty liability survived. The earlier finding of bona fide belief and the setting aside of the related penalty under Rule 173Q also supported the view that penal and interest consequences could not survive independently.

Conclusion: Penalty under Section 11AC and interest under Section 11AB were not sustainable.

Final Conclusion: The Revenue's challenge failed in full, and the order dropping the duty demand and ancillary liabilities was maintained.

Ratio Decidendi: Where an exemption notification is amended to insert an entry that merely clarifies an omission in a consistent exemption scheme across predecessor and successor notifications, the amendment may be applied retrospectively; once no duty survives, penalty and interest connected to that demand cannot be sustained.
