Factual and Procedural Background
The appeal concerns whether an arbitral tribunal had substantive jurisdiction to determine if a claim by an investor fell within the protections under a free trade agreement (FTA) between two States, or whether the tribunal's jurisdiction could be challenged under section 67 of the Arbitration Act 1996 ("the 1996 Act") on grounds that the claim fell outside the treaty's scope.
Chapter 11 of the FTA between the Appellant ("Korea") and the United States of America ("the USA"), signed in 2007 ("the Treaty"), provides protections to investors, effectively functioning as a bilateral investment treaty. Article 11.1(1) defines the scope of protections relating to measures adopted or maintained by a State concerning investors or their investments ("covered investments"). Article 11.16 allows investors to submit claims to arbitration for breaches of these protections, with Article 11.17 providing consent for arbitration.
In April 2018, the Appellee ("Elliott"), a USA investment fund, initiated UNCITRAL arbitration against Korea alleging improper interference by Korean State entities in a merger involving a Korean company in which Elliott invested, breaching the Treaty’s National Treatment and Minimum Standards of Treatment obligations. Korea challenged the tribunal's jurisdiction, arguing the claim did not fall within Chapter 11's scope.
In June 2023, the tribunal issued an award finding Korea's conduct constituted a "measure" under the Treaty, breached the Minimum Standard of Treatment, and awarded damages to Elliott. Korea applied to set aside the award under section 67 of the 1996 Act, contending the tribunal exceeded its substantive jurisdiction. The application was dismissed by the trial judge ("the Judge") in August 2024, who held that the offer to arbitrate in Article 11.16 was freestanding and not conditional on Article 11.1(1)’s requirements. The Judge granted permission to appeal given the importance of the legal issue.
Subsequently, diplomatic notes exchanged between the USA and Korea confirmed their shared understanding that Article 11.1 defines the scope of Chapter 11 and that tribunals lack jurisdiction unless its requirements are met. Korea sought to admit this as fresh evidence in support of its appeal.
Legal Issues Presented
- Whether the arbitral tribunal had substantive jurisdiction to determine if the investor's claim fell within the protections under Chapter 11 of the Treaty.
- Whether the jurisdiction of the tribunal is subject to challenge under section 67 of the 1996 Act on grounds that the claim fell outside the scope defined by Article 11.1(1).
- Whether Article 11.1(1) imposes jurisdictional conditions on the offer to arbitrate contained in Article 11.16 of the Treaty.
- The admissibility and effect of subsequent diplomatic notes as supplementary means of treaty interpretation under the Vienna Convention on the Law of Treaties 1969 ("VCLT").
Arguments of the Parties
Appellant's Arguments
- Article 11.1(1) of the Treaty sets jurisdictional requirements that must be satisfied for the offer to arbitrate in Article 11.16 to be valid.
- The Judge erred by introducing national policy considerations into the interpretation of an international treaty.
- The Judge should have accepted supplementary means of interpretation, including post-signature material and ITA tribunal awards, under Article 32 of the VCLT.
- The diplomatic exchange between the States confirms that Article 11.1 defines the scope of Chapter 11 and limits tribunal jurisdiction.
Appellee's Arguments
- The offer to arbitrate in Article 11.16 is freestanding and not conditional on the requirements of Article 11.1(1).
- Article 11.1(1) defines the scope of substantive protections but does not limit the procedural right to arbitrate disputes under Section B of Chapter 11.
- Challenges based on Article 11.1(1) engage merits rather than jurisdiction for the purposes of section 67.
- Subsequent material and ITA awards are not binding and do not constitute supplementary means of interpretation under the VCLT.

Court's Reasoning and Analysis
The Court undertook a detailed analysis of Chapter 11 of the Treaty, focusing on the interpretation of Articles 11.1(1) and 11.16, applying the principles of treaty interpretation under Articles 31 and 32 of the VCLT. The Court noted that Article 11.1(1) states that "This Chapter" applies to certain measures, indicating that the scope and coverage provision governs the entire Chapter 11, including Section B on dispute resolution.
The Judge had held that Article 11.1(1) limited the substantive protections but did not restrict the offer to arbitrate claims under Article 11.16, which was viewed as a freestanding procedural provision. The Court rejected this, reasoning that the ordinary meaning of "This Chapter" encompasses both substantive and procedural provisions, and that it was improbable that the phrase was used mistakenly in successive treaties.
The Court considered provisions such as Articles 11.11 (Denial of Benefits) and 11.14 (Subrogation), which refer to rights "under this Chapter," and concluded these must include the offer to arbitrate, undermining the Judge’s separation of Sections A and B.
The Court also rejected the Judge’s reliance on national policy considerations and English domestic law presumptions about jurisdictional issues, holding that treaty interpretation is governed by international law principles and must be consistent across jurisdictions.
ITA tribunal awards under NAFTA were examined; while these generally treat the equivalent provision as jurisdictional, the Court distinguished the Treaty at issue due to differences in provisions and procedural context. The Court acknowledged the Singapore International Commercial Court’s decision in Mason, which agreed with the Judge, but found the reasoning unpersuasive to the extent it conflicted with the Court’s conclusions.
The Court concluded that Article 11.1(1) imposes jurisdictional conditions on the offer to arbitrate in Article 11.16, meaning the tribunal’s jurisdiction depends on the claim satisfying the scope and coverage requirements of Article 11.1(1).
The Court declined to decide on the admissibility or effect of the diplomatic notes or supplementary materials under Article 32 of the VCLT, as the appeal’s outcome did not require it.
Holding and Implications
The Court issued the following holding:
The appeal is allowed.
The Court held that Article 11.1(1) of the Treaty sets jurisdictional requirements which must be satisfied for the offer to arbitrate in Article 11.16 to be effective. Consequently, the tribunal’s jurisdiction is conditioned on the claim falling within the scope and coverage defined by Article 11.1(1).
The effect of this decision is that the Appellant's application under section 67 of the 1996 Act must be referred back to the Commercial Court for determination on the merits, as the tribunal’s jurisdictional boundaries require reconsideration under the correct interpretation.
No new precedent beyond the interpretation of the Treaty provisions was established, and the decision primarily affects the procedural posture of the arbitration challenge between the parties.
