Retrospective penalty and interest barred where the statutory amendment came after the disputed credit reversal period.

Penalty and interest could not be imposed for a period preceding the amendment to Rule 57-I, because the legal basis for those liabilities came into force only on 1-3-1997. The credit had already been wrongly taken but was reversed, and the duty demand itself was not disputed. As the disputed period was April 1996 to June 1996, the penal and interest provisions could not be applied retrospectively. The duty demand remained undisturbed, but the penalty and interest were set aside.

Issues: Whether penalty and interest could be imposed for a period prior to the amendment to Rule 57-I when the credit had already been reversed and the duty demand was not disputed.

Analysis: The credit was taken wrongly, but it had been reversed and the duty demand itself was not challenged. The disputed period was April 1996 to June 1996, whereas the amendment enabling penalty and interest under Rule 57-I came into force only on 1-3-1997. Since the legal basis for penalty and interest was introduced after the period in dispute, those liabilities could not be fastened for the earlier period.

Conclusion: Penalty and interest were not leviable for the disputed period and were rightly set aside.

Final Conclusion: The duty demand remained undisturbed, but the assessee obtained relief from the penal and interest components, resulting in a partial allowance of the appeal.

Ratio Decidendi: A penalty or interest provision cannot be applied to transactions predating the statutory amendment that creates or enlarges such liability.
