The Leaflet: Reading Nagaraj Mylandla — Transnational Issue Estoppel finds its footing in India

LAST MONTH, the Supreme Court published its judgment in Nagaraj V. Mylandla v. PI Opportunities Fund. The case arose from a special leave petition against Madras High Court’s judgement in PI Opportunities Fund – I v. FSSPL (2025) which had allowed the enforcement of an international arbitration award against the appellant award debtor. While the Supreme Court’s judgment upholding the Madras High Court’s judgment, and thereby allowing the enforcement of the award, was broadly anticipated. In doing so, the Court for the first time recognised the doctrine of transnational issue estoppel under Indian law. This is a notable development as it strengthens India’s stated pro-arbitration policy approach.

The Court notes that applying the doctrine helps prevent parties from re-litigating factual issues already settled by the seat court, merely because they are now before a different court in another jurisdiction. This, in turn, narrows the scope of interference available to the enforcement court and strengthens the finality of arbitral awards that have already been upheld at the seat.
