Retrospective tax validation defeated interest and penalty where the assessee complied within the prescribed revival period.

Retrospective validation of Goods Transport Operator service tax liability was treated as regularising the assessee's obligation under the later statutory scheme. Because the assessee paid the tax and filed the return within the period prescribed by the validating provision and notification, the alleged default could not support interest under Section 75 of the Finance Act, 1994 or penalty under Section 76. The stated legal effect is that timely compliance with a revived tax framework defeats punitive consequences for the earlier affected period, and the demand for interest and penalty was set aside.

Issues: Whether, after retrospective revival of the service tax liability on Goods Transport Operator services, the assessee was liable to interest and penalty for the period in question, despite having paid the tax and filed the return within the time prescribed by the subsequent statutory scheme and notification.

Analysis: The liability arising from availing Goods Transport Operator service for the relevant period had earlier been affected by the declaration that the relevant provisions of the Service Tax Rules, 1994 were ultra vires. The later validating provisions in Section 71A of the Finance Act, 2003 and the corresponding notification required the persons concerned to file the return and pay the tax within the stipulated period. The assessee had paid the service tax within time under the revived statutory framework. On that basis, the failure alleged in the impugned order could not sustain a demand of interest under Section 75 of the Finance Act, 1994 or penalty under Section 76 of the Finance Act, 1994.

Conclusion: The demand of interest and the penalty were held unsustainable and were set aside in favour of the assessee.

Final Conclusion: The assessee's compliance within the period prescribed by the subsequent validating provisions defeated the levy of interest and penalty, and the appeal succeeded.

Ratio Decidendi: Where a retrospective validating provision regularises a previously affected tax liability and the assessee complies within the time prescribed under that scheme, interest and penalty cannot be imposed for the earlier non-compliance.
