Validation of service tax compliance barred interest and penalty where tax return and payment were made within the later prescribed time.

For Goods Transport Operator service for 16.11.1997 to 02.06.1998, the validating legislation and later notification required assessees who had availed the service during that period to file the return and pay tax within the prescribed time. The appellants complied by paying the service tax and filing the return within time under the post-validation framework. In that setting, the conditions for imposing interest and penalty were not met, because the earlier liability had arisen under provisions later treated as ultra vires. Interest and penalty were therefore not sustainable, and the impugned order was set aside.

Issues: Whether interest and penalty were exigible for failure to comply with service tax requirements in respect of Goods Transport Operator service for the period 16.11.1997 to 02.06.1998, after the subsequent validating provisions and the relevant notification.

Analysis: The liability arose in the context of provisions under the Service Tax Rules that had earlier been struck down as ultra vires. The validating legislation and the subsequent notification required persons who had availed the service during the relevant period to file the return and pay the tax within the prescribed time. The appellants had paid the service tax and filed the return within time under the later regime. In such circumstances, the conditions for fastening interest and penalty under the impugned order were not satisfied.

Conclusion: Interest and penalty were not sustainable; the impugned order was set aside and the assessee succeeded.

Final Conclusion: The revision-based demand of interest and penalty could not be sustained after the valid payment and compliance under the post-validation framework.

Ratio Decidendi: Where the assessee complies within the time prescribed under the validating notification and the later statutory framework, interest and penalty cannot be imposed for the earlier period covered by provisions already declared ultra vires.
