Clarificatory amendment to exemption notification operates retrospectively, extending customs exemption to imported BOPP films.

An explanatory amendment to an exemption notification was treated as clarificatory, meaning it reflected the original legislative intent rather than creating a new benefit. On that basis, the amendment operated retrospectively, so the customs exemption extended to BOPP films imported for manufacture of electronic capacitor grade metallised dielectric plastic film. The Tribunal relied on its earlier ruling in the same matter and the finality of the Supreme Court's dismissal of the Revenue's civil appeal on the identical issue. The differential duty demand was therefore not sustainable, and the exemption benefit applied from the inception of the notification.

Issues: Whether the amendment introduced by Notification No. 20/2001 dated 1.3.2001 to Notification No. 25/99 dated 28.2.1999 was clarificatory and retrospective, so as to extend the customs exemption to BOPP films imported by the appellant.

Analysis: The imported goods were BOPP films used in the manufacture of electronic capacitor grade metallised dielectric plastic film. The Tribunal relied on its earlier decision in the appellant's own case involving the same notification entry, where the explanation inserted by Notification No. 20/2001 was held to clarify the original scope of the exemption and not to create a new benefit for the future. The subsequent dismissal of the Revenue's civil appeal by the Supreme Court was treated as giving finality to that identical issue, supporting the view that the amendment operated retrospectively. On that basis, the Tribunal held that the explanation merely reflected the legislative intent already embedded in the original notification.

Conclusion: The amendment was held to be retrospective and clarificatory, and the appellant was entitled to the exemption benefit.

Final Conclusion: The demand of differential duty was not sustainable, and the appeals succeeded with consequential relief.

Ratio Decidendi: Where an explanatory amendment to an exemption notification is intended to clarify the original scope of the notification, it operates retrospectively and the benefit must be extended from the inception of the notification.
