Procedural Background

This document is the Decision of the ad hoc Committee constituted under the ICSID Convention to hear an application for annulment filed by the Kingdom of Spain. Spain sought the annulment of the Arbitral Award rendered on October 6, 2023, in ICSID Case No. ARB/15/23, which found Spain liable for breaching its obligations under the Energy Charter Treaty (ECT) and ordered it to pay compensation to the claimants (Mathias Kruck and others).

Grounds for Annulment and Parties' Positions

Spain's application for annulment was based on two grounds under Article 52(1) of the ICSID Convention: (b) manifest excess of powers, and (e) failure to state the grounds on which the Award is based.

Spain argued that the Arbitral Tribunal manifestly exceeded its powers by improperly asserting jurisdiction over an intra-EU dispute, contending that EU law precludes the application of the ECT's arbitration clause between an EU Member State and investors from another EU Member State. Spain further alleged an excess of powers in the Tribunal's failure to apply EU law, particularly State aid rules, to the merits of the dispute. Regarding the failure to state reasons, Spain asserted that the Award did not adequately explain its findings on the claimants' legitimate expectations, particularly in light of EU State aid rules, and contained contradictory reasoning.

The claimants (Respondents on Annulment) countered that the Tribunal's decision on jurisdiction was a tenable interpretation of the ECT and did not meet the high threshold of a "manifest" excess of powers. They argued that the Tribunal correctly identified international law as the governing legal framework and that the Award provided a clear and coherent rationale for its findings, thereby satisfying the requirement to state reasons.

The Committee's Analysis and Decision

The ad hoc Committee unanimously dismissed Spain's application. The Committee underscored that annulment is an extraordinary remedy and not an appeal, requiring a "manifest" or self-evident error.

On the alleged manifest excess of powers, the Committee found that the Arbitral Tribunal's jurisdictional reasoning was tenable. The Tribunal had based its competence on the plain text of the ECT and the ICSID Convention, concluding that these international law instruments governed its mandate. The Committee noted that this conclusion was consistent with a significant body of ICSID jurisprudence, which confirmed that the Tribunal's position was not a manifest error. The Committee also held that the Tribunal's reasoned decision to apply international law, rather than EU law, to the merits did not constitute a disregard of the applicable law but a substantive determination beyond the scope of annulment review.

On the alleged failure to state reasons, the Committee found that the Award contained a clear, coherent, and understandable line of reasoning regarding the claimants' legitimate expectations under the ECT's fair and equitable treatment standard. The Tribunal's decision not to apply EU State aid rules was a direct and logical consequence of its prior determination on the applicable law, and therefore did not represent a "missing link" in its reasoning. The Committee also found no contradiction in the Tribunal's analysis of the evidence concerning investor expectations.

Operative Part

The Committee rejected Spain's application for annulment in its entirety. It ordered Spain to bear all costs of the annulment proceedings, its own legal costs, and 90% of the claimants' legal costs.
