Exemption notification for CTD bars construed by legislative intent; later amending notification treated as clarificatory and retrospective.

CTD bars were treated as falling within the exemption under Notification No. 202/88-C.E. on the basis of legislative intent, departmental understanding, and trade materials. A later amending notification, Notification No. 170/89-C.E., was regarded as merely clarificatory and therefore retrospective in operation, so it did not introduce a new restriction but explained the original scope of the exemption. On that construction, CTD bars satisfied the conditions of the notification and were covered by the exemption, with relief granted to the assessee on the exemption issue.

Issues: Whether CTD bars were covered by exemption Notification No. 202/88-C.E. dated 20.05.1988 and whether Notification No. 170/89-C.E. dated 16.08.1989 was clarificatory and retrospective in operation.

Analysis: The issue was treated as covered by earlier decisions holding that the later amending notification was clarificatory in nature and therefore had retrospective effect. The exemption was construed in the light of the legislative intent, the accepted departmental understanding, and the treatment of the goods in the relevant trade and administrative materials. On that approach, CTD bars were regarded as satisfying the conditions of the exemption and as falling within the scope of the notification.

Conclusion: The issue was answered in favour of the assessee. Notification No. 170/89-C.E. was held to be clarificatory, and CTD bars were held to be covered by the exemption.

Final Conclusion: The appeal succeeded and the assessee obtained relief on the exemption issue.

Ratio Decidendi: An exemption notification may be construed in the light of legislative intent, and a subsequent amending notification that merely clarifies the original scope operates retrospectively.
