In The Republic of India v. Deutsche Telekom AG [2024] 1 SLR 56, the Singapore Court of Appeal (“SGCA”) issued a landmark judgment. The SGCA held that the doctrine of transnational issue estoppel which is well established in the context of foreign judgments, applies also in international commercial arbitration. This doctrine prevents a party from raising the same grounds of challenge to resist enforcement of an arbitral award, after those grounds had already been litigated in setting-aside proceedings.
The SGCA observed that the New York Convention did not operate in isolation because the domestic law of the enforcement court also came into play, which in Singapore included principles of transnational issue estoppel. Further, the court held that applying the doctrine of transnational issue estoppel also respected the parties' choice of a seat in a principled manner.
The SGCA suggested that under the “primacy” principle, a seat court’s decision on matters relating to the validity of an award would be “presumptively determinative” before an enforcement court. It offered four reasons for applying the “primacy” principle in Singapore: the principle (i) recognises the seat court’s unique role in supervising the arbitral award and aligns with the “territorialist view” of arbitration (which Singapore subscribes to); (ii) advances judicial comity; (iii) gives weight to the parties’ choice of the arbitral seat; and (iv) promotes the finality of awards (SGCA decision, para. 121).
The decision highlights the importance of choosing an arbitration seat, as the decision of the seat on issues such as jurisdiction may, in some instances such as the present case, be given preclusive effect in the enforcement courts. This decision promotes finality and certainty in international arbitration in preventing an award debtor from derailing enforcement proceedings by re-litigating the same issues in each jurisdiction in which the award is sought to be enforced.
