GSTAT Surat Holds Taxpayer Can Seek GST Refund Even Without Being Party to Case

In a significant ruling that reinforces the remedial scope of constitutional tax jurisprudence, the Goods and Services Tax Appellate Tribunal (GSTAT), Surat, has held that a taxpayer is entitled to claim a refund of tax paid under a levy subsequently declared unconstitutional, even if the taxpayer was not a party to the proceedings that struck down the levy. The decision, rendered in a batch of 46 departmental appeals, provides clarity on the retrospective operation of declaratory judgments and the boundaries of unjust enrichment in the GST regime.

The Core Dispute: IGST on Ocean Freight

The controversy arose from the levy of Integrated Goods and Services Tax (IGST) on ocean freight under the reverse charge mechanism. Filatex India Limited, a manufacturer and exporter of polyester yarn, had paid IGST on the ocean freight component of imported goods. The levy was predicated on notifications issued under the Integrated Goods and Services Tax Act, 2017. However, in the landmark case of Mohit Minerals Pvt. Ltd. v. Union of India , the Gujarat High Court declared those notifications ultra vires the IGST Act and unconstitutional. The Supreme Court dismissed the Union government’s appeal against that judgment on May 19, 2022, thereby affirming the declaration of invalidity.

Filatex, which had not been a party to the Mohit Minerals litigation, filed refund applications before the jurisdictional GST authorities, seeking repayment of the IGST it had paid on ocean freight. The department rejected the claims on multiple grounds, prompting Filatex to appeal to the Appellate Authority, which allowed the refunds. The department then challenged those orders before the GSTAT, Surat.

Department’s Objections Rejected

The department advanced three principal arguments against the refund. First, it contended that the Mohit Minerals judgment did not expressly state that it would operate retrospectively, and therefore Filatex could not rely on it to reopen past transactions. Second, the department argued that Filatex had availed and utilised the IGST input tax credit, and that granting a cash refund would result in unjust enrichment. Third, it maintained that only the parties to the Mohit Minerals case could benefit from the judgment.

The tribunal, comprising Judicial Member Sanjaykumar Dwivedi and Technical Member Rameshkumar G. Hadvani, systematically dismantled each objection.

Retrospective Effect of Declaratory Judgments

On the question of retrospectivity, the tribunal held that a judgment declaring a levy unconstitutional operates from the very inception of the levy. It observed: “The declaration by the court that the levy was ab initio void is itself the legal foundation for entitlement to refund. No further order in the name of the claimant is required. The entitlement to refund flows directly from Article 265 and does not depend on adjudication inter partes.”

The tribunal emphasised that unless a court specifically directs that its judgment shall apply prospectively, all declaratory judgments are retrospective in nature. Since the Supreme Court, while dismissing the Union’s appeal, did not impose any temporal limitation on the Mohit Minerals ruling, the declaration of unconstitutionality applied from the date the notifications were issued. Consequently, Filatex’s payment of IGST under an invalid levy was without legal authority, and the refund was justified.

No Unjust Enrichment Despite Credit Utilisation

The department’s unjust enrichment argument was particularly intricate. The department pointed out that Filatex had availed input tax credit of the IGST paid on ocean freight and had utilised that credit to discharge its output tax liability. Allowing a cash refund, the department argued, would give Filatex a double benefit.

The tribunal examined the credit ledger of Filatex and found that although the IGST credit had been booked and utilised, the company maintained a combined unutilised balance of Central GST and State GST that was equivalent to the refund amount. The tribunal reasoned that in substance, the IGST credit had not been effectively utilised because the offsetting unutilised balances remained. “This amounted to non-utilisation of the credit in substance and did not result in a double benefit,” the tribunal held. It further noted that the refund of cash, when combined with the reversal of the credit entry, would restore the taxpayer to the position it would have been in had the levy never existed.

Taxpayer Need Not Be Party to the Litigation

Perhaps the most far-reaching aspect of the ruling is the rejection of the department’s contention that only the petitioners in Mohit Minerals could claim refunds. The tribunal relied on the principle laid down by the Supreme Court in Mafatlal Industries Ltd. v. Union of India , which carved out a narrow exception: a person who had personally challenged the validity of the levy, lost that challenge, and allowed the decision to attain finality, cannot later claim a refund based on another person’s successful challenge. However, that exception did not apply to Filatex because it had never litigated the constitutional question.

“The Respondent paid tax under that very levy. It did not itself litigate the question of constitutional validity and lose on the constitutional question,” the tribunal observed. Therefore, Filatex was entitled to rely on the Mohit Minerals judgment, even though it was not a party. This holding reinforces the general rule that a declaration of unconstitutionality inures to the benefit of all taxpayers similarly situated, subject only to the narrow Mafatlal bar.

Interest and Directions

The tribunal directed the department to process the refund claims and pay the amounts along with interest under Section 56 of the CGST Act for any delay beyond 60 days from the date of the original refund applications. This direction underscores the compensatory nature of refunds and the obligation of the revenue to promptly return money collected without legal authority.

Implications for Taxpayers and Revenue

The GSTAT Surat’s decision carries significant implications for the GST ecosystem. First, it clarifies that the Mohit Minerals ruling is not a closed chapter for taxpayers who did not participate in that litigation. Thousands of importers and exporters who paid IGST on ocean freight under reverse charge can now pursue refund claims without fear of being turned away on procedural grounds.

Second, the ruling provides a template for handling refunds arising from judicially invalidated levies. The tribunal’s nuanced treatment of input tax credit utilisation—distinguishing between mere booking of credit and its effective economic consumption—offers a practical framework that other benches and the revenue may adopt.

Third, the decision reiterates the primacy of Article 265 of the Constitution, which mandates that no tax shall be levied or collected except by authority of law. A levy declared unconstitutional is void ab initio , and the taxpayer’s right to refund flows directly from this constitutional command, independent of any procedural bar.

Conclusion

The GSTAT Surat’s ruling is a robust affirmation of taxpayer rights in the context of unconstitutional levies. By holding that retrospective effect is inherent in declaratory judgments, that unjust enrichment must be assessed in substance rather than form, and that the benefit of a successful constitutional challenge extends to all similarly situated taxpayers, the tribunal has laid down principles that will guide refund jurisprudence for years to come. The department’s appeals were dismissed, and Filatex India Limited stands to recover the IGST it paid on ocean freight, along with interest. This decision is likely to spur a wave of refund claims and may prompt the revenue to reconsider its opposition to such claims in similar fact patterns.
