Supreme Court overruled itself. The taxman still can't recover refunds paid under old law.

When the Supreme Court changed its mind, could the tax department take back refunds already paid?

M/s Saraswati Agro Chemicals Pvt. Ltd. had done everything right. It paid education cess on its excise duty. Then the Supreme Court, in M/s SRD Nutrients (P) Limited v. CCE (2018) 1 SCC 105, said that if excise duty was exempt, education cess was also exempt. So the company applied for a refund. The Central Excise Department granted it. Money changed hands. The file was closed.

Two years later, the Supreme Court changed its mind. In M/s Unicorn Industries v. Union of India (2020) 3 SCC 492, a different bench held that SRD Nutrients was decided per incuriam — it had missed an earlier three-judge bench decision in Modi Rubber Ltd. and Anr. v. Union of India and Others (1986) 4 SCC 66. Education cess, the Court now said, must be paid even when excise duty is exempt.

The Revenue saw an opportunity. It began recovery proceedings against every assessee who had received a refund under the now-overruled SRD Nutrients. Saraswati Agro Chemicals was one of them. The company had already spent that money. Now the taxman wanted it back.

The stakes were enormous — not just for this one company, but for every business that had relied on a Supreme Court judgment that later got overruled. Could the government reopen settled tax refunds every time the law changed? The answer, the Supreme Court finally said on July 4, 2023, is a firm no.

The refund that came with a time bomb

The story begins with a straightforward tax dispute. Saraswati Agro Chemicals, a company based in Jammu & Kashmir, was in the business of manufacturing goods subject to excise duty. Under the Central Excise Act, 1944, it also had to pay Education Cess and Secondary & Higher Education Cess — levies imposed under the Finance Act — calculated as a percentage of the total excise duty.

In 2018, the Supreme Court decided SRD Nutrients. The question was simple: if the government exempts excise duty under a notification, does that exemption also cover the education cess payable on that duty? The Court said yes. The logic was that education cess was a tax on the excise duty itself — if the base duty was exempt, the cess on it fell away too.

Relying on this binding precedent, Saraswati Agro Chemicals applied for a refund of the education cess it had paid. The Central Excise Department processed the claim and issued the refund. The company received the money. That should have been the end of it.

But in 2020, the Supreme Court decided Unicorn Industries. A different bench held that SRD Nutrients had been wrongly decided. It had failed to consider Modi Rubber Ltd., a three-judge bench decision that had taken the opposite view. The Court declared SRD Nutrients per incuriam — decided without regard to binding precedent — and overruled it. Education cess, the Court now held, was a separate levy that survived even when the underlying excise duty was exempt.

The Revenue wasted no time. It began issuing recovery notices to every assessee who had obtained a refund under the now-dead SRD Nutrients ruling. Saraswati Agro Chemicals received one such notice. The company was told to return the refunded amount, with interest.

What the High Court said

Saraswati Agro Chemicals challenged the recovery before the High Court of Jammu & Kashmir and Ladakh at Jammu. The company's argument was simple: when we applied for the refund, SRD Nutrients was the law of the land. We relied on it in good faith. The Department itself processed and granted the refund. You cannot now change the rules after the game is over.

The Revenue countered with an equally straightforward argument: SRD Nutrients was always bad law. It was decided per incuriam. A judgment that ignores binding precedent is void from the start. The refund was therefore granted under a mistake of law, and the Department is entitled to recover it.

On May 23, 2022, the High Court ruled against the Revenue. It held that the refunds had been made under a binding judgment of the Supreme Court that was the law at the relevant time. A subsequent overruling could not reopen matters that had already attained finality. To allow such recovery, the High Court observed, would create endless litigation and destroy the certainty that taxpayers need to plan their affairs.

The Revenue appealed to the Supreme Court.

The Supreme Court's answer: finality matters more than correctness

Before the Supreme Court, the Additional Solicitor General made a spirited attempt. He argued that SRD Nutrients was per incuriam because it had not considered Modi Rubber Ltd. — a three-judge bench decision. A judgment that is per incuriam has no binding force. The refund was therefore granted without legal authority, and the Department could recover it as money paid under a mistake.

The Bench, comprising Justice B.V. Nagarathna (who authored the judgment) and Justice Prashant Kumar Mishra, was not persuaded. The Court identified three separate legal principles that barred the Revenue's attempt.

First: the Explanation to Order XLVII Rule 1 CPC

Order XLVII Rule 1 of the Code of Civil Procedure, 1908, deals with review of judgments. Its Explanation states that a subsequent judgment overruling an earlier judgment on a point of law does not, by itself, constitute a ground for reviewing the earlier judgment. The Supreme Court applied this principle directly: the fact that Unicorn Industries overruled SRD Nutrients did not give the Revenue a right to reopen the refund that had already been granted under SRD Nutrients.

Second: Order XLVII Rule 9 CPC — no second review

The Court noted that the Revenue had already filed a review petition against the High Court's judgment, which had been dismissed. After that dismissal, the Revenue filed a miscellaneous application seeking to reopen the matter. The Court held that this was, in substance, a second review petition — which is expressly barred by Order XLVII Rule 9 CPC. You cannot do indirectly what the law forbids you to do directly.

Third: the principle of finality

This was the heart of the matter. The Supreme Court endorsed the High Court's reasoning that past decisions that have attained finality cannot be reopened on the basis of a subsequent overruling. The Court observed that the Revenue's approach would lead to chaos: every time the Supreme Court overruled a precedent, every taxpayer who had relied on the old law would face recovery proceedings. That is not how a stable tax system works.

The Court also noted that the Revenue's reference order dated September 27, 2021 — which sought to refer SRD Nutrients to a larger bench — was unnecessary. By that time, Unicorn Industries had already overruled SRD Nutrients, and the review petition had been dismissed. The reference served no purpose.

THE PLAY: If you received a tax refund under a Supreme Court judgment that was later overruled, the Revenue cannot recover that refund — the principle of finality and the Explanation to Order XLVII Rule 1 CPC bar such recovery, even if the overruled judgment was declared per incuriam.

Why this matters for every business and tax lawyer

This judgment is a powerful shield for taxpayers. It establishes a clear rule: when the government grants a refund based on a binding Supreme Court judgment, that transaction is final. The government cannot come back later and demand repayment simply because the law has changed.

For advocates, the case is a masterclass in procedural defences. The Revenue had a strong substantive argument — SRD Nutrients was indeed per incuriam. But the Court did not engage with that argument on the merits. Instead, it shut the door using procedural rules: the Explanation to Order XLVII Rule 1, the bar on second reviews, and the overarching principle of finality. When the substantive law is against you, procedural law can save you.

For CFOs and founders, the message is equally important. If your company receives a tax refund based on a court judgment, you can treat that money as yours. The government cannot claw it back years later because a different court took a different view. This certainty allows businesses to plan their finances without the fear of retrospective tax demands.

The judgment also has implications for how the Revenue handles cases where the Supreme Court overrules its own precedents. The Court has made it clear: the Revenue cannot use a subsequent overruling as a backdoor to reopen settled assessments and refunds. If the Revenue wants to challenge a refund, it must do so within the normal appellate process — not by filing miscellaneous applications after review petitions have been dismissed.

The bottom line

When the Supreme Court dismissed the Revenue's Special Leave Petition on July 4, 2023, it did more than just save Saraswati Agro Chemicals from repaying a refund. It affirmed a principle that every taxpayer in India can now rely on: a refund granted under a binding Supreme Court judgment is final, and the government cannot take it back just because the Court later changed its mind.
