Retrospective excise exemption requires restoration to the pre-change duty level; partial rate reduction does not support refund.

Retrospective exemption under the Central Duties of Excise (Retrospective Exemption) Act, 1986 applies only where a post-1-3-1986 notification restores the duty incidence to the level prevailing before the tariff change. The notification for insulated wires and cables reduced the rate from 30% to 25%, but did not return it to the earlier 10% level. It therefore did not qualify for retrospective operation, and the refund claim was not admissible. The refund rejection was upheld.

Issues: Whether Notification No. 231/86-C.E. dated 03-04-1986 could be given retrospective effect so as to sustain the refund claim under the Central Duties of Excise (Retrospective Exemption) Act, 1986.

Analysis: The applicable retrospective exemption regime operated only where post-1-3-1986 exemptions restored the duty position to the level prevailing before the tariff change. The rate on insulated wires and cables had moved from 10% under the earlier tariff to 30% under the new tariff and was later reduced to 25% by the notification. Since the notification did not restore the pre-1-3-1986 duty level, it did not fall within the protective scope of the retrospective exemption legislation.

Conclusion: The notification was not entitled to retrospective operation and the refund claim was not admissible.

Final Conclusion: The appeal failed and the order rejecting the refund position was sustained.

Ratio Decidendi: Retrospective exemption applies only where a post-change notification restores the duty incidence to the pre-change level; a mere partial reduction does not attract retrospective operation.
