Procedural Background

This document is the final Award rendered by a majority of an ICSID tribunal in the arbitration between Watkins Holding S.à.r.l. and other investors (Claimants) and the Kingdom of Spain (Respondent). The dispute, brought under the Energy Charter Treaty (ECT), concerned Claimants' investments in several wind farm projects in Spain and the subsequent radical overhaul of Spain's renewable energy regulatory framework.

Jurisdictional Objections

The Tribunal first addressed Spain's two jurisdictional objections. Unanimously, it rejected the Respondent's intra-EU objection, which argued that the ECT's dispute settlement provisions do not apply to disputes between an investor from one EU Member State and another EU Member State. The Tribunal affirmed that its jurisdiction is founded on public international law, specifically the ECT and the ICSID Convention, which operate in a legal order distinct from that of the European Union. It found no explicit or implicit "disconnection clause" in the ECT that would oust its jurisdiction and held that the Court of Justice of the European Union's decision in *Achmea* was not determinative for this multilateral treaty context.

However, the Tribunal unanimously upheld Spain's second objection concerning the tax carve-out under ECT Article 21. It found that it lacked jurisdiction over claims related to the 7% tax on the value of electricity production (the "TVPEE") introduced by Law 15/2012, as this measure qualified as a *bona fide* taxation measure excluded from the treaty's substantive protections.

Analysis of the Merits

On the merits, a majority of the Tribunal found that Spain had breached its obligation to accord Fair and Equitable Treatment (FET) under ECT Article 10(1). The Tribunal determined that Spain, through its RD 661/2007 regime and subsequent official representations, had created specific commitments and induced legitimate expectations of a stable, predictable, and favorable regulatory framework to attract investment in its renewable energy sector. The Claimants reasonably relied on these commitments when making their substantial investments.

The majority held that the series of legislative and regulatory measures enacted by Spain between 2012 and 2014—culminating in the complete repeal of the RD 661/2007 regime and its replacement with a new, less favorable system based on a "reasonable rate of return"—constituted a fundamental and radical alteration of the legal framework. This overhaul frustrated the Claimants' legitimate expectations and violated the stability inherent in the FET standard. The Tribunal rejected Spain's defense based on its sovereign right to regulate, finding the measures to be unreasonable and disproportionate in light of the specific stability commitments made.

Decision on Quantum and Costs

The majority awarded the Claimants damages in the amount of €77 million for the breach of the ECT. The quantum was determined using a Discounted Cash Flow (DCF) analysis, with the valuation date set at 20 June 2014, when the new regulatory regime was fully implemented and the harm to the investment crystallized. The Tribunal awarded pre-award interest at 1.16% and post-award interest at 2.16%, both compounded monthly. The Claimants' request for a tax gross-up was dismissed. By majority, the Tribunal ordered Spain to pay 75% of the Claimants' costs. Arbitrator Hélène Ruiz Fabri issued a Dissenting Opinion on issues of liability and quantum.

Procedural Background and Issues

This document is the Arbitral Tribunal's decision on the Kingdom of Spain's post-award application, filed pursuant to Article 49(2) of the ICSID Convention, for the rectification of the Award rendered on 21 January 2020. Spain also requested a stay of enforcement of the Award pending the outcome of its rectification request.

Spain's application for rectification was based on two principal grounds. First, it alleged a clerical error in the damages calculation, contending the Tribunal mistakenly awarded EUR 77 million based on future damages only, whereas the correct figure, including past damages, should have been EUR 97.7 million. Second, Spain argued that after declining jurisdiction over the Claimants' claim concerning a 7% tax on electricity production (the TVPEE), the Tribunal failed to neutralize the impact of this tax in its damages model, which constituted a rectifiable error.

The Tribunal's Analysis and Decision

The Tribunal, by majority, denied both the request for rectification and the application for a stay of enforcement. The Tribunal began by affirming the limited scope of Article 49(2), which permits the correction of "clerical, arithmetical or similar error" but does not serve as a mechanism for substantive review or appeal of the merits of an award.

On the first alleged error concerning past damages, the Tribunal found that its decision to reject claims for losses prior to the date the breach crystallized (20 June 2014) and to award EUR 77 million was a deliberate and reasoned decision based on its findings on the merits. It was therefore not a clerical error subject to rectification. On the second alleged error regarding the TVPEE, the Tribunal determined that Spain's request constituted a novel argument not raised during the main proceedings. Addressing it would require a complex re-evaluation of evidence and expert reports, far exceeding the scope of a simple correction and amounting to an impermissible review of the Award's substance.

Regarding the stay of enforcement, the Tribunal held that it lacked jurisdiction to grant such relief in the context of a rectification proceeding. Relying on the persuasive authority of the decision in Masdar v. Spain, the Tribunal concluded that the ICSID Convention and Arbitration Rules provide for a stay of enforcement only in connection with applications for interpretation, revision, or annulment (Articles 50-52), not rectification under Article 49.

Disposition and Costs

The Tribunal dismissed Spain's Request for Rectification and its application for a stay of enforcement in their entirety. Applying the principle that costs follow the event, the Tribunal ordered Spain to bear the Claimants' legal costs incurred in the rectification proceeding, amounting to EUR 63,293.39, as well as the Claimants' share of the proceeding's costs, amounting to USD 36,772.13.

Procedural Posture

This Memorandum Opinion, issued by the United States District Court for the District of Columbia, addresses post-judgment motions following the September 2025 confirmation of a €77 million ICSID arbitral award in favor of Blasket Renewable Investments against the Kingdom of Spain. The underlying dispute involved violations of the Energy Charter Treaty (ECT). Following the entry of judgment, the Petitioner initiated post-judgment discovery to locate attachable Spanish assets.

Issues Addressed and Parties' Positions

Spain filed motions to stay the enforcement of the judgment without posting a supersedeas bond and to quash third-party subpoenas issued by the Petitioner to various financial institutions. Spain argued that Section 1610(c) of the Foreign Sovereign Immunities Act (FSIA) barred post-judgment discovery until a court determined that a "reasonable period of time" had elapsed, and further contended that European Union law prohibited its voluntary payment of the award. In response, the Petitioner opposed the stay and cross-moved for declaratory relief under 28 U.S.C. § 1610(c) to attach and execute on Spain's assets, and under 28 U.S.C. § 1963 to register the judgment in other judicial districts nationwide.

Court's Analysis and Findings

The Court denied Spain's motions in their entirety. Applying the standard for unbonded stays under Federal Rule of Civil Procedure 62, the Court found no "unusual circumstances" justifying a departure from the standard supersedeas bond requirement. The Court firmly rejected Spain's reliance on FSIA § 1610(c) to halt discovery, citing the Supreme Court's holding in Republic of Argentina v. NML Capital, Ltd., which established that the FSIA does not limit post-judgment discovery in aid of execution. Furthermore, the Court determined that Spain's refusal to pay based on European Commission directives actually weighed against granting a stay. Spain's stated legal inability to voluntarily satisfy the judgment demonstrated an unwillingness to pay, thereby endangering the Petitioner's interest in ultimate recovery and justifying immediate enforcement efforts.

Operative Directions

The Court granted the Petitioner's cross-motions, ruling that a "reasonable period of time" had elapsed under FSIA § 1610(c), thus permitting the attachment and execution of Spain's assets. Additionally, the Court found "good cause" under 28 U.S.C. § 1963 to allow the Petitioner to register the judgment in all other judicial districts of the United States, given the absence of sufficient executable assets in the District of Columbia and the likelihood of attachable, potentially mobile assets in other jurisdictions, such as New York.

Procedural Context and Issues

This Memorandum and Order, issued by the United States District Court for the District of Columbia, resolves two post-judgment discovery disputes arising from an action to enforce a confirmed ICSID arbitral award against the Kingdom of Spain. The petitioner, having obtained a final judgment, is seeking to identify attachable assets pursuant to Federal Rule of Civil Procedure 69(a)(2). The disputes concerned: (1) whether two Spanish state-owned entities, Sociedad Estatal de Participaciones Industriales (“SEPI”) and Instituto Cervantes, could be subjected to direct party discovery as part of "Spain"; and (2) Spain's motion to quash third-party subpoenas served on its defense contractors, Raytheon and Palantir.

The Court's Rulings and Analysis

The Court first addressed the status of SEPI and Instituto Cervantes. It sustained Spain's objection to treating these juridically separate entities as part of the judgment debtor for discovery purposes. The Court reasoned that the petitioner had not yet met the burden of showing that the entities were alter egos of Spain or that Spain exercised sufficient control to compel their production of documents. The ruling was made without prejudice, allowing the petitioner to seek an alter ego finding via a motion to compel after conducting further discovery on the relationship between the entities and the state.

Second, the Court granted Spain's motion to quash the subpoenas directed to Raytheon and Palantir. While acknowledging the broad scope of post-judgment discovery, the Court invoked principles of comity owed to a foreign sovereign. It determined that the subpoenas, which sought highly sensitive information related to Spain's military and national security, should be deferred. The Court directed the petitioner to prioritize discovery of less sensitive assets to satisfy the judgment before pursuing information that implicates core sovereign interests. This decision was also granted without prejudice, permitting the petitioner to reissue the subpoenas if other avenues for satisfying the judgment prove insufficient.

Operative Orders

The Court ordered that Spain's objection regarding SEPI and Instituto Cervantes is sustained without prejudice. It further ordered that Spain's Motion to Quash the subpoenas to Raytheon and Palantir is granted without prejudice.

Procedural Posture

This document is a Joint Motion to Govern Further Proceedings filed before the United States Court of Appeals for the District of Columbia Circuit. The filing addresses five consolidated appeals brought by the Kingdom of Spain challenging district court judgments that enforced international arbitral awards rendered under the Energy Charter Treaty. Following the United States Supreme Court’s denial of Spain’s petition for certiorari in a related enforcement action (NextEra), the D.C. Circuit directed the parties to propose a schedule for further appellate proceedings.

Parties' Positions on Briefing and Stay

Spain requests that the Court hold panel briefing in abeyance pending the disposition of its forthcoming petition for initial en banc review. Spain contends that en banc consideration is necessary to revisit threshold issues concerning the Foreign Sovereign Immunities Act (FSIA) and forum non conveniens, arguing that the D.C. Circuit’s prior precedent in NextEra was wrongly decided. Spain relies heavily on a recent amicus curiae brief filed by the United States Solicitor General, which criticized the NextEra panel’s analysis of the FSIA arbitration exception.

The Appellees strongly oppose any further stay or elongation of the briefing schedule. They argue that initial en banc review is highly disfavored and unlikely to be granted, noting the Court’s recent denial of en banc review in NextEra. Appellees characterize Spain’s proposed stay as a dilatory tactic designed to obstruct ongoing post-judgment execution and attachment proceedings. Consequently, Appellees request the implementation of a standard briefing schedule to ensure the expeditious resolution of the enforcement appeals.
