Introduction
Foreign private equity and venture capital investors have long treated Indian court proceedings as the single biggest risk to a clean exit. An arbitral award obtained in months or years abroad has, in the past, been dragged through Indian enforcement courts for years more, with promoters recycling the same factual and contractual arguments that the seat court had already rejected.
The Supreme Court’s ruling in Nagaraj V. Mylandla v. PI Opportunities Fund-I [2026 INSC 298] directly addresses this problem by formally adopting the doctrine of transnational issue estoppel into the Indian arbitration enforcement framework. This ruling has immediate consequences for how PE/VC exit clauses are drafted, how foreign arbitral awards are enforced under the Arbitration and Conciliation Act, 1996, and how Indian courts treat the buyback restrictions under the Companies Act, 2013.
The Enforcement Problem Behind PE/VC Exit Disputes in India
According to a 2023 report by the Indian Private Equity and Venture Capital Association, roughly 15 percent of all private equity exits in India between 2018 and 2022 involved some form of dispute, translating to approximately 75 disputed exits out of 500 total exits in that period, with the average dispute stretching to 4.7 years and some running past a decade.
International arbitration was meant to shorten this timeline by giving investors a faster route to a binding award. That advantage disappears if the award debtor can simply repeat the same defeated arguments before an Indian enforcement court under the guise of a public policy objection. The Supreme Court’s ruling in Mylandla closes this loophole by holding that a promoter who has already lost an issue before the seat court cannot relitigated that same issue before an Indian court at the enforcement stage.
How Exit Waterfalls Work in Minority PE/VC Investments
Almost every minority PE/VC investment in India is structured around a defined, time-bound exit mechanism written into the shareholders’ agreement. These clauses typically set out a sequential waterfall: an initial public offering within a fixed timeline, followed by a strategic sale if the IPO does not happen, and a buy-back by the company as the remedy of last resort. If none of these exits materialise as scheduled, the shareholders’ agreement usually treats this as an “event of default” or “material breach,” triggering consequences such as a put option requiring the promoter to acquire the investor’s shares at a premium, subject to foreign exchange law, or a drag-along right compelling a full sale.
In practice, promoters and investors frequently return to the negotiating table rather than immediately invoking the dispute resolution clause, since a public dispute depresses company valuation, unsettles management, and can trigger lender covenant scrutiny. Arbitration is typically invoked only once negotiations have genuinely broken down. The Mylandla ruling matters precisely because it protects the integrity of this waterfall once arbitration does become necessary, by making sure the resulting award is not diluted through years of enforcement litigation in India.
Background: The FSSPL Investment and the SIAC Arbitration
In 2014, Financial Software and Systems Private Limited received an investment from venture capital investors under a Share Acquisition and Shareholders Agreement. The exit structure followed the classic waterfall model: a qualified IPO planned for March 2016, followed by a secondary sale at an agreed exit price if the IPO failed, then a company buy-back, an investor-led IPO, and finally a strategic sale or merger. A failure by FSSPL or its promoters to deliver an exit was defined as a material breach, triggering remedies including strategic sale and buy-back.
The qualified IPO never happened. Secondary sale notices were issued in 2016 and reissued in 2020 and 2021. When these efforts also failed, the investors issued material breach notices, termination-of-rights notices, and strategic sale notices simultaneously, and commenced arbitration before the Singapore International Arbitration Centre, seated in Singapore.
The SIAC Award and the Damages-at-Exit-Price Structure
In July 2024, the arbitral tribunal ruled in favour of the investors, awarding damages calculated at the agreed exit price. To pre-empt any argument of double recovery or unjust enrichment, the investors offered to surrender their shares once the damages were paid. The tribunal’s reasoning rested on the finding that the transaction documents imposed an absolute obligation on FSSPL and its promoters to deliver an exit, and that failing to do so amounted to a material breach of the shareholders’ agreement.
The Buyback Defence Before the Singapore High Court
The promoters challenged the award before the General Division of the High Court of Singapore, arguing among other things that the award violated Indian law. Their core argument was that paying damages at the exit price in exchange for the investors surrendering their shares effectively operated as a share buy-back, which they claimed would breach the buy-back restrictions under the Companies Act, 2013. The Singapore High Court rejected this argument, holding that it was, in substance, an impermissible attempt to reopen the merits of the arbitral award rather than a genuine jurisdictional or public policy challenge.
Enforcement Before the Madras High Court Under Sections 47–49
Having lost before the seat court, the investors approached the Madras High Court under Sections 47 to 49 of the Arbitration and Conciliation Act, 1996, to enforce the award as a decree. The promoters raised the identical buy-back argument that the Singapore High Court had already dismissed. The Madras High Court rejected the objection and held the award enforceable as a decree under Section 49 of the Act.
Distinguishing Surrender from Buyback Under Sections 66 to 68 of the Companies Act, 2013
A central plank of the Madras High Court’s reasoning was the distinction between a “surrender” of shares by an investor and a “buy-back” by a company as regulated under Sections 66 to 68 of the Companies Act, 2013. The Court observed that the arbitral award neither directed FSSPL to repurchase the shares nor specified to whom the surrendered shares were to be transferred, and therefore did not trigger the statutory buy-back conditions and limitations under the Companies Act at all.
On this basis, the Madras High Court invoked the doctrine of transnational issue estoppel to prevent the promoters from reagitating an issue that the Singapore High Court had already conclusively decided, and imposed costs of INR 25 lakh payable to each investor for attempting to relitigate settled findings purely to delay enforcement.
The Supreme Court’s Ruling: Transnational Issue Estoppel Becomes Part of Indian Arbitration Law
The promoters approached the Supreme Court by way of a Special Leave Petition, arguing that the Madras High Court had erred in applying transnational issue estoppel to what they characterised as a public policy challenge. The Supreme Court disagreed and held that where an issue has been fully argued and conclusively decided by the seat court, the award debtor cannot relitigate that same issue before an Indian enforcement court.
The Narrow Scope of the Public Policy Ground
The Supreme Court clarified that an enforcement court in India retains the authority to examine an award on the limited ground of violation of the public policy of India, which remains available under the framework of the Arbitration and Conciliation Act, 1996. However, the Court held firmly that contentions on the merits of a dispute that have already been rejected by the seat court cannot be smuggled back into an Indian enforcement proceeding by dressing them up as a public policy objection.
Applying this principle, the Supreme Court affirmed the Madras High Court’s finding distinguishing buy-back from surrender of shares and held that once the Singapore High Court had rejected the promoters’ objection on this point, it could not be raised again before the Indian enforcement court.
Costs for Repeated Relitigation
The Supreme Court endorsed the INR 25 lakh costs imposed by the Madras High Court and went further, imposing an additional INR 25 lakh per investor for what it described as a “mudslinging effort” made before the Court. The escalating cost orders across both the High Court and Supreme Court signal that Indian courts are prepared to financially penalise award debtors who use enforcement proceedings as a delay tactic rather than a genuine legal challenge.
What Mylandla Means for Drafting PE/VC Exit Clauses in India
The ruling validates carefully layered exit waterfalls by giving independent legal effect to each remedy in the sequence rather than treating them as interchangeable or collapsible. It also confirms that a clause requiring written waivers protects an investor’s participation in restructuring discussions from being read as a waiver of its right to pursue other contractual remedies later.
For transactional lawyers structuring shareholders’ agreements, the practical takeaway is to frame the ultimate exit remedy as damages calculated at the exit price coupled with a voluntary surrender of shares as a fallback, rather than a structure that could be characterised as a disguised buy-back under Sections 66 to 68 of the Companies Act, 2013. Equally important is the choice of arbitral seat: parties should select a seat with a well-established and predictable arbitral regime, since the Mylandla ruling means that a seat court’s decision on the merits will now travel with the award into Indian enforcement proceedings and cannot be reopened there.
Key Takeaways
Transnational issue estoppel is now a formally recognised part of India’s arbitration enforcement regime. Once a seat court has upheld an award on its merits, an Indian enforcement court will not entertain the same objections again, except strictly on the narrow ground of public policy under the Arbitration and Conciliation Act, 1996, which itself cannot be used to reopen matters already decided on the merits.
Indian promoters and companies that treated contractual exit obligations toward PE/VC investors as aspirational rather than binding now face a materially different risk calculus: a breach of a properly drafted exit clause can result in a foreign arbitral award that is enforced in India without years of repeated litigation. The Mylandla ruling, read together with the Sections 47 to 49 enforcement framework and the Sections 66 to 68 buy-back provisions of the Companies Act, 2013, makes the end-to-end path from arbitral award to Indian enforcement considerably more predictable than it has historically been for foreign investors.
Conclusion
The Supreme Court’s decision in Nagaraj V. Mylandla v. PI Opportunities Fund-I is significant well beyond its facts. By endorsing transnational issue estoppel, the Court has directly addressed one of the most persistent complaints of foreign PE/VC investors in India: that a favourable arbitral award is only the first step in a much longer battle fought all over again in Indian courts.
With this ruling, a seat court’s findings on the merits now carry forward into Indian enforcement proceedings, the distinction between buy-back and surrender of shares under the Companies Act, 2013 is judicially settled, and the narrow public policy exception under the Arbitration and Conciliation Act, 1996 has been reaffirmed rather than expanded. For investors, promoters, and the lawyers who draft their exit clauses, Mylandla is now the reference point for how enforceable a PE/VC exit remedy in India truly is.
The cross-border considerations explored in Cross-Border Legal Privilege in International Arbitration are equally relevant to disputes involving foreign judgments and issue estoppel, particularly in the context of international investment and PE/VC exit transactions.
