Intra-EU Investment Treaty Disputes in US Courts: Achmea, Micula and Beyond
In Micula, a US federal district court enforced an award pursuant to the ICSID Convention over objections from Romania and the European Commission based on Achmea. Micula should encourage parties pursuing claims under intra-EU treaties of their prospects for enforcement in the United States. However, the district court’s reasoning did not foreclose the relevance of EU law in proceedings to enforce intra-EU awards before US courts. Since Micula, claimants have continued bringing intra-EU treaty claims and seeking enforcement of the resulting awards in the United States. The European Commission remains hostile to intra-EU investor-state arbitration and raises Achmea to oppose such arbitration and enforcement of the resulting awards. Future decisions may further clarify the attitude of US courts towards intra-EU investor-state awards.

Now nearing its second anniversary, a Washington, DC federal district court’s decision in Ioan Micula et al v Government of Romania remains a key reference point for investors seeking to enforce intra-EU arbitration awards in US courts. Micula marked the US judiciary’s first decision considering the enforceability of an investor-state arbitration award made pursuant to a bilateral investment treaty (an intra-EU BIT) between two EU member states after the Court of Justice of the European Union (CJEU) ruled, in Slovak Republic v Achmea, that investor-state arbitration among EU member states was contrary to the constitutional order of the European Union.
The decision in Micula, affirmed by the DC Circuit in May of 2020, shows that so far as US courts are concerned, awards based on intra-EU BITs are potentially enforceable. At the same time, the court’s decision in Micula does not foreclose the relevance of the CJEU’s decision in future proceedings to enforce intra-EU investor-state awards before US courts and leaves significant questions unanswered.
Micula’s ambiguities are significant because, notwithstanding Achmea and the European Commission’s long-standing position that the resolution of investment disputes within the European Union should occur only within the framework of the EU’s own legal system, European investors continue to bring treaty claims against EU member states. Around 66 such intra-EU claims are currently pending before the International Centre for Settlement of Investment Disputes (ICSID) alone. Some of those cases were filed quite recently, even though a majority of EU member states agreed in 2020 to terminate more than 130 intra-EU investment treaties with retroactive effect.
In addition, Micula is significant because enforcement actions in respect of over US$560 million worth of intra-EU investor-state awards are pending before US federal district courts. This article considers the potential implications of the Micula decision for the treatment of intra-EU awards in US federal courts as the European Commission seeks to expand the scope of the Achmea ruling and maintains its hostility to intra-EU investor-state arbitration.
The Micula ICSID arbitration
The Micula arbitration arose as a consequence of Romania’s preparations for its entry into the European Union in 2007. Romania had earlier extended certain economic incentives to encourage foreign investment in its new post-Soviet economy. The claimants, two brothers of Swedish nationality but Romanian heritage, had relied on these incentives when investing in the food and beverage industry of an impoverished region of Romania.
Although the incentives had been meant to last for at least a decade, they were withdrawn as part of Romania’s efforts to bring itself into compliance with the acquis communautaire in preparation for its EU accession. The European Commission had advised Romania that, from the standpoint of European law, the incentives at issue constituted unlawful ‘state aid’ that distorted incentives and created uneven treatment within an integrated single European economy.
Alleging breaches of their legitimate, investment-backed expectations as protected under the Swedish-Romanian BIT’s fair and equitable treatment clause, the Miculas commenced arbitration before ICSID in August of 2005. After an ICSID tribunal found their claims admissible, the European Commission warned that any award reinstating the privileges abolished by Romania, or compensating the investors for the loss of those privileges, would itself constitute state aid contrary to the supremacy of EU law.
The arbitral tribunal refused, however, to subordinate Romania’s international law obligations under the BIT to the Commission’s view of European law. It instead refused to ‘assume that by virtue of entering into the [EU] Accession Treaty or by virtue of Romania’s accession to the EU, either Romania, or Sweden, or the EU sought to amend, modify or otherwise detract from the application of the BIT’. The tribunal ultimately awarded the Micula claimants compensation of approximately €178 million in December 2013 plus interest.
Shortly thereafter, the European Commission issued an order purporting to enjoin Romania from complying with the award. The Micula claimants promptly challenged that order before the European Union’s General Court. Romania, meanwhile, sought review of the award before an ad hoc annulment committee within the framework of the ICSID Convention. The annulment committee refused Romania’s request to stay enforcement of the award until the conclusion of the annulment procedure, however, because Romania refused to promise that it would comply with the award if it was upheld by the Committee.
While annulment proceedings continued, the Micula claimants sought to enforce their award before various national courts. Article 54 of the ICSID Convention obliges each contracting state to the ICSID Convention to enforce an ICSID award ‘as if it were a final judgment of a court in that state’. A petition for enforcement of the award was filed with the United States federal district court in Washington DC on 11 April 2014.
Achmea decision issued while the Miculas’s petition was pending in Washington, DC
The CJEU, the European Union’s highest judicial body, issued its decision in Achmea while the Micula claimants’ enforcement action was pending before the federal district court in Washington, DC.
The background to the CJEU’s decision in Achmea was as follows: a Dutch investor had brought a claim against Slovakia pursuant to the Netherlands-Slovakia BIT of 1992, challenging measures taken by the government that had adversely impacted its investments in the health insurance sector. The resulting arbitration was conducted pursuant to the UNCITRAL Arbitration Rules with the arbitration seated in Germany.
Achmea prevailed in the arbitration. However, Slovakia immediately applied to annul the resulting award on the theory that investor-state arbitration under the treaty was contrary to EU law. Rather than decide the question itself, the German Federal Court of Justice referred the question to the CJEU.
In its judgment, the CJEU found that the dispute at issue could require the tribunal to apply EU law and that its resolution within an investor-state arbitration would be final and not fully reviewable before the courts of a European member state or the European courts, or both. This, the CJEU reasoned, threatened ‘consistency and uniformity in the interpretation of EU law’.
Accordingly, the CJEU explained, EU law ‘must be interpreted as precluding a provision in an international agreement concluded between member states . . . under which an investor from one of those member states may, in the event of a dispute concerning investments in the other member state, brings proceedings against the latter . . . before an arbitral tribunal’.
The Micula district court rejected a jurisdictional challenge based on Achmea
Under the ICSID Convention and US law, there are no grounds for challenging an ICSID award in the US courts. Pursuant to 22 USC section 1650a, a federal court is obliged to treat an ICSID award as having the status of a final court from another US state. It may not ‘examine an ICSID award’s merits, its compliance with international law, or the ICSID tribunal’s jurisdiction to render the award’. A district court’s role when presented with an ICSID award comprises nothing more than an ‘examin[ation of] the award’s authenticity and enforce[ment of] the obligations imposed’. Consistent with the ICSID Convention’s self-contained annulment mechanism, review of ICSID awards is thus much more narrowly circumscribed than that of awards governed by the New York Convention.
Romania, however, used Achmea as the basis for an attack on the district court’s subject-matter jurisdiction in respect of a dispute involving a sovereign (Romania) under the US Foreign Sovereign Immunities Act (FSIA). Under US law, the FSIA is ‘the sole basis for obtaining jurisdiction over a foreign state’ in a US court.
The Micula claimants had pleaded that the court had subject-matter jurisdiction over the enforcement of their award against Romania pursuant to the FSIA’s ‘arbitration exception’, which provides that ‘[a] foreign state shall not be immune . . . in any case . . . in which the action is brought . . . to confirm an award made pursuant to . . . an agreement to arbitrate, if . . . the . . . award is governed by a treaty or other international agreement in force for the United States calling for the recognition and enforcement of arbitral awards’. Romania (and the European Commission as amicus curiae) countered that the FSIA’s arbitration exception could not apply because, consistent with the CJEU’s ruling in Achmea, the arbitration agreement contained in the applicable treaty had been retroactively nullified upon Romania’s accession to the European Union.
Although an ICSID ad hoc annulment committee had already rejected this very argument, the US district court proceeded to conduct its own analysis. It ultimately found that ‘the concern that animated Achmea – the unreviewability of an arbitral tribunal’s determination of EU law by an EU court’ was not present in the case before it and enforced the award. The district court did so for two main reasons.
First, the court observed that, unlike in Achmea, ‘all key events to the parties’ dispute occurred before Romania acceded to the EU’, such that, ‘unlike in Achmea . . . Romania’s challenged actions [i.e. the cancellation of the investment incentives] occurred when it remained outside the EU and subject, at least primarily, to its own domestic law.’
Second, the court found that EU law was not yet controlling on Romania at the time of the measures complained of, such that the arbitration did not ‘“relate to the interpretation or application of EU law” in the sense that concerned the court in Achmea’. The district court appears to have been comforted in this conclusion by the EU General Court’s ruling, while the case was pending, that Romania’s incentive scheme did not violate EU law.
Having thus distinguished Achmea, the district court rejected Romania’s challenge to subject-matter jurisdiction under the FSIA, dismissed other arguments based on the European Union’s state aid law as moot and ordered judgment for the Micula claimants in the amount of US$331 million. The DC Circuit in May 2020 affirmed per curiam on other grounds, noting in dicta that ‘as the district carefully explained, Romania did not join the EU until after the underlying events here, so the arbitration agreement applied’.
Questions raised by the district court decision in Micula
Micula will naturally encourage claimants seeking to enforce intra-EU investor-state awards in the United States. But it does not take the arguments raised by Romania based upon Achmea off the table. On the contrary, the district court’s opinion in Micula makes clear that parties seeking to enforce awards based upon intra-EU bilateral investment treaties will have to focus on distinguishing Achmea.
On the Micula district court’s approach, key questions likely to arise are:
- whether the measures being challenged under an investment treaty occurred prior to or after a respondent state’s EU accession; and
- the degree to which resolution of the dispute involves an arbitral tribunal in the ‘interpretation or application of EU law’.
The district court’s approach in Micula – if not its result – may, thus, have created uncertainty about the extent to which US courts will effectuate the United States’ treaty obligations – incorporated in federal statute – to enforce investor-state awards under the ICSID Convention.
The district court’s approach is open to question in at least three respects.
First, although it accurately stated the standard applied in ICSID enforcement cases, the district court does not seem to have applied it. Under 22 USC section 1650a, the statute implementing the United States’ obligations under article 54 of the ICSID Convention, an ICSID ‘award shall be enforced and shall be given the same full faith and credit as if the award were a final judgment of a court of general jurisdiction of one of the several states’.
That is why, as the Micula district court recognised, ‘a federal court is not permitted to examine an ICSID award’s merits, its compliance with international law, or the ICSID tribunal’s jurisdiction to render the award’, all of which are questions for the arbitral tribunal under the ICSID framework. A court’s role is limited to confirming the award’s authenticity and enforcing its obligations as a judgment.
In Micula, an ICSID tribunal had already found that it had jurisdiction over the parties, and its conclusion had been upheld by an ICSID annulment committee. Where ICSID tribunals have the power to decide upon their own jurisdiction pursuant to article 41 of the ICSID Convention, there is a strong argument that the jurisdictional findings reached within the arbitration should have been accepted by the district court.
The second respect in which the district court’s approach is open to question is that the Micula district court does not appear to have considered an alternative basis for subject-matter jurisdiction under the FSIA, which would have entirely avoided the need to engage with EU law. In particular, the FSIA authorises a court to exercise subject-matter jurisdiction where a state has waived its sovereign immunity. There is a reasonable argument that by becoming a party to the ICSID Convention, Romania waived any objection to subject-matter jurisdiction in a foreseeable future action to enforce an ICSID award.
The district court’s Achmea analysis was directed at determining whether the FSIA’s arbitration exception applied on the basis of a valid arbitration agreement in an intra-EU investment treaty, a finding of waiver could have sidestepped analysis of the treaty itself entirely. The DC Circuit’s holdings in Creighton v Qatar and Tatneft v Ukraine, namely that a sovereign’s adoption of the New York Convention waived its immunity from suits to enforce arbitration awards under its terms in other states that signed the New York Convention, supports a waiver theory. Such an approach could make it easier for federal district courts to avoid parsing the significance of Achmea while honouring the United States’ international law obligations to enforce ICSID awards.
The third respect in which the district court’s approach is open to question is that it is questionable whether the district court distinguished sufficiently between public international law and specifically European law. The DC Circuit’s brief statement that ‘Romania did not join the EU until after the underlying events here, so the arbitration agreement applied’ arguably implies that Achmea would otherwise have negated the agreement to arbitrate contained in the Swedish-Romanian treaty and pre-empted the United States’ own treaty obligation to enforce ICSID awards.
A difficulty, however, is that the ICSID Convention is a public international law instrument that imposes obligations on the United States, while Achmea is part of a specifically European legal order that does not. Investor-state tribunals and ICSID annulment committees have consistently emphasised the distinction between public international law and European law in rejecting challenges to their jurisdiction based on the CJEU’s reasoning in Achmea.
For its part, the Micula decision does not provide a clear explanation of why – had the court found its facts more closely analogous to Achmea’s – European law should have prevailed over the United States’ own treaty obligations under article 54 of the ICSID Convention.
Micula’s approach could be more pertinent in the case of a non-ICSID award for which enforcement would be sought under the New York Convention. A respondent state might attempt to challenge the validity of the underlying arbitration agreement pursuant to article V of the New York Convention. This might be attempted pursuant to article V(1), which allows (but does not require) a court to withhold recognition and enforcement of a foreign award where the parties to the underlying arbitration agreement ‘were, under the law applicable to them, under some incapacity, or the said agreement is not valid under the law to which the parties have subjected it’. That is fundamentally the position of the European Commission, adopted by the CJEU in Achmea, and by award debtor states resisting enforcement of intra-EU investment treaty awards.
Alternatively, an argument could conceivably be made under article V(2) of the New York Convention that a US court’s recognition of an intra-EU investor-state award in spite of the views of the CJEU and European Commission (and presumably also of the respondent state) that the award was contrary to European law would be contrary to US public policy.
Even then, however, there would likely be a strong argument for deference to a tribunal’s jurisdictional determination – including of questions related to Achmea – since the applicable arbitration rules would almost certainly have entrusted jurisdictional questions to the tribunal. In practice, US courts will, where possible, avail themselves of the opportunity to leave questions of European law to the courts of a foreign arbitral seat with primary jurisdiction over an award.
In Novenergia v Spain, for example, a federal district court stayed proceedings to enforce an Energy Charter Treaty (ECT) award in favour of Luxembourg investors pending the decision of the courts of Sweden, the arbitral seat, in respect of whether Achmea’s reasoning applies to an ECT Award. In so doing, the court observed that the issues presented by Achmea were ‘of importance to the EU and better suited for initial review in their courts’.
Similarly, US federal district courts in several pending actions to enforce intra-EU ICSID awards have issued stays pending the result of ICSID annulment proceedings, even when the ad hoc committees constituted to review those same awards under the ICSID Convention had lifted the provisional stay imposed in annulment cases under the ICSID Convention and allowed enforcement to go forward.
Micula will not be the US courts’ last word on intra-EU investor-state awards. Pending and future cases will almost certainly afford the district courts and perhaps the DC Circuit an opportunity to rule on some of the uncertainties identified above.
New issues will arise as well. As reflected in Novenergia, for example, the scope of Achmea is itself unsettled. EU member states are divided on whether its holding applies to intra-EU investment arbitration under the ECT, a sector-specific, multilateral agreement that provides for investor-state arbitration and to which many non-EU states, as well as the European Union itself, are parties. This is important because a large proportion of the intra-EU investor-state awards for which enforcement is being sought before US courts are ECT awards arising out of disputed reforms to Spain’s solar energy sector.
This question has added urgency in the context of another major development: in May 2020, 23 of the 27 EU member states announced a ‘Termination Agreement’ intended to ‘implement’ the Achmea judgment by terminating their intra-EU BITs. This agreement is currently in force for 13 EU states.
Although member states had previously pledged to terminate their intra-EU BITs, the Termination Agreement goes farther: it requires signatories to resist intra-EU awards and is explicitly retroactive. The Termination Agreement also requires states to resist awards concluded before the Achmea judgment, while ostensibly requiring parties to intra-EU investor-state arbitration pending at the time of the Achmea judgment to enter into ‘structured dialogue’ to reach a settlement and obliging European investor claimants to suspend their claims.
Unusually, the Termination Agreement also purports to cancel ‘sunset clauses’ in the relevant treaties. Such clauses would otherwise extend the period of the relevant treaty for a term of years after notice of its termination.
The Termination Agreement does not apply to arbitration under the ECT nor does it purport to affect participating states’ obligations under the ICSID Convention. Although the right of states to terminate treaties is beyond serious question, it is not clear that the retroactive aspects of the Termination Agreement are proper under public international law or that investor-state tribunals will accept them. The Termination Agreement does, however, demonstrate the depth of the European Commission’s opposition to intra-EU BITs and is sure to give rise to complex questions about the proper relationship of European and public international law.
The enforceability of intra-EU arbitral awards rendered under the ECT in Europe is uncertain. Although the Termination Agreement does not explicitly apply to arbitration conducted pursuant to the ECT, the European Commission has not concealed its hostility to intra-EU arbitration arising under the treaty.
Moreover, on 3 March 2021, a CJEU Advocate General issued an opinion arguing that Achmea should be extended to bar intra-EU arbitration under the ECT – a significant development that does not, however, bind the CJEU. Days earlier, a Swedish court had referred this very question to the CJEU, potentially giving the court the opportunity to issue a companion ruling to Achmea.
At the same time, ICSID tribunals have continued to find that they have jurisdiction to hear intra-EU arbitration arising under the ECT. If the CJEU makes a formal ruling that Achmea applies to intra-EU ECT arbitration, the importance of US courts as a strategic forum is likely only to increase as investors seek a forum in which to enforce their intra-EU ICSID awards.
The decision in Micula has raised many questions and left many unanswered. It is plainly not the end of the story: investors continue to initiate arbitration proceedings and petition US courts to enforce intra-US awards.
US courts are, thus, certain to be considering efforts to enforce those awards for the foreseeable future, and jurisprudence in this area will continue to evolve in the backdrop of an increasingly hostile enforcement environment in Europe. It is critical that US courts address the questions raised by Micula.
Nearly two years on, however, Micula remains the applicable precedent and signals that, Achmea notwithstanding, intra-EU investor-state awards remain enforceable in the United States, if not quite assuredly so.

 Investor-state awards subject to enforcement under the New York Convention are subject to limited but still significantly broader judicial review than ICSID awards. When made at a foreign seat, recognition of such awards may be challenged before a US court on the non-merits grounds listed in the New York Convention. See New York Convention (1958), articles V(1) and (2). US-seated awards may also be challenged pursuant to the grounds for vacatur enumerated in Chapter 1 of the Federal Arbitration Act.

Instead, ICSID award creditors are still required ‘to file a plenary action, subject to the ordinary requirements of process under the Foreign Sovereign Immunities Act’.

 The General Court reasoned that the incentives, and payment of compensation for their cancellation, did not violate EU state aid rules because the relevant events all preceded Romania’s entry into the European Union and the applicability of European law. Judgment of the General Court (Second Chamber, Extended Composition) of 18 June 2019 in Cases T-624/15, T-694/15 and T-704/15 European Food SA and Others v European Commission (Micula) (discussed in Micula v Gov’t of Romania, 404 F. Supp. 3d 265, 277 (D.D.C. 2019)). The European Commission appealed the General Court’s decision to the CJEU. See appeal brought on 27 August 2019 by the European Commission against the judgment of the General Court (Second Chamber, Extended Composition) (18 June 2019) in Case T-624/15: European Food ea v Commission (Case C-638/19 P) (2019/C 348/15).
 Romania also alleged that the act of state and foreign compulsion doctrines prohibited the award’s enforcement and that it had already fully satisfied the award. The district court found both of these defences ‘overtaken by events’ given the EU General Court’s finding that payment of the Micula award would not violate EU state aid rules. Micula v Gov’t of Rom, 404 F. Supp. 3d at 281. The district court also rejected Romania’s satisfaction defence on the facts. See id. at 285.

 See Mobil Cerro Negro, 863 F.3d at 102. See also id. at 121 (observing that the ICSID-award debtor can make ‘non-merits challenges’ to an award, such as to ‘the authenticity of the award presented for enforcement, the finality of the award, or the possibility that an offset might apply to the award that would make execution in the full amount improper’). This limited role ‘reflects an expectation [under the Convention] that the courts of a member nation will treat the award as final.’ Micula, 404 F. Supp. 3d at 275-76.

 International investment tribunals have consistently rejected intra-EU jurisdictional objections. As expressed in categorical terms by the RREEF v Spain tribunal, ‘in all published or known investment treaty cases in which the intra-EU objection has been invoked by the Respondent, it has been rejected. The present decision on this point therefore falls squarely within the continuity of this consistent pattern of decision-making by international tribunals.’ RREEF v Spain, ICSID Case No. ARB/13/30, Decision on Jurisdiction (Jun. 6, 2016) ¶ 89 (emphasis added). More recently, the ICSID Annulment Committee in Sodexo Pass International SAS v Hungary observed that not a single ICSID tribunal has held that Achmea renders an intra-EU BIT’s arbitration clause null and void and unanimously rejected Hungary’s challenge to the award. See Jack Ballantyne, ‘Intra-EU award against Hungary upheld’, Global Arbitration Review (25 May 2021); Sodexo Pass International SAS v Hungary, ICSID Case No. Arb/14/20 (May 7, 2021).

Notably, in a case brought by the Micula claimants in connection with efforts to enforce their award in the United Kingdom, the UK Supreme Court found that while EU law might control when interpreting a treaty exclusively among EU member states, it could not displace the United Kingdom’s award enforcement obligations under the ICSID Convention, which were owed not just to EU member states but to all states party to the ICSID Convention.

 See the ECT, 34 I.L.M. 360, 385 (1995). It is estimated that some 60 per cent of ECT arbitrations concern intra-EU disputes. See Johannes Tropper, ‘The Energy Charter Treaty and its (in)compatibility with EU law: To be or not to be, that is the question?’ Völkerrechtsblog (17 December 2020). In turn, roughly 45 per cent of intra-EU treaty-based arbitrations are brought under the ECT. See UNCTAD, ‘Fact Sheet on Intra-European Union Investor-State Arbitration Cases’, IIA Issue Note 3.2018, p. 1. EU member states are divided about whether the ECT should meet the same fate as intra-EU bilateral investment treaties. When, in January of 2019, the then-28 EU member states announced their intention to terminate all intra-EU bilateral investment treaties, only 22 were willing to take the position that Achmea also applied to intra-EU investor-state arbitration under the ECT. See Declaration of the Representatives of the Governments of the Member States of 15 January 2019 on the Legal Consequences of the Judgment of the Court of Justice in Achmea and on Investment Protection in the European Union (22 signatories). Another six member states found Achmea ‘silent’ in respect of the ECT. Five of these (Sweden, Luxembourg, Finland, Malta and Slovenia) urged that the issue be allowed to be further developed in litigation before member state courts, while Hungary more affirmatively asserted the position that Achmea did not apply to ECT claims. See also Tom Jones, ‘EU countries to cancel BITs post-Achmea,’ Global Arbitration Review (17 January 2019).

Signatories of the Termination Agreement are Belgium, Bulgaria, Croatia, Republic of Cyprus, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia and Spain. As at the time of writing, four ‘holdouts’ – Austria, Finland, Ireland and Sweden – have yet to ratify the Agreement.

 Despite Brexit in January 2020, the European Commission has commenced ‘infringement proceedings’ against both the United Kingdom and Finland for having declined to sign the Termination Agreement. The Commission maintains that EU law continues to apply to UK BITs until the end of 2020. See Tom Jones, ‘UK and Finland face legal action over intra-EU BITs’, Global Arbitration Review (14 May 2020). In October 2020, the Commission issued a ‘reasoned opinion’ maintaining the right to refer the United Kingdom to CJEU if it does not terminate its BITs with EU member states but has not taken further action. See European Commission press corner, ‘October Infringements Package: Key Decisions’ (30 October 2020); Mark McCloskey, ‘Safe Haven for Investors in (and Through) the UK Post-Brexit?’, AJIL Insights (24 February 2021).
 See Termination Agreement, article 9. In addition, article 7 of the Termination Agreement requires states to: (1) inform tribunals about the alleged legal consequences of the Achmea judgment; and (2) request that national courts (including non-EU courts) set the arbitral award aside, annul it or refrain from recognising or enforcing it. The Termination Agreement does not affect arbitration in which a final award or settlement was reached before 6 March 2018 (the date of the CJEU’s Achmea decision), provided that the award was at that date duly executed with no challenge pending. See Agreement for the Termination of Bilateral Investment Treaties between the Member States of the European Union SN/4656/2019/INIT OJ L 169, 29.5.2020.
 The Termination Agreement purports to make such sunset clauses ineffective, both under treaties terminated as a consequence of the Agreement, as well as under previously terminated treaties of which the sunset clauses would otherwise have remained in effect. See Termination Agreement, articles 2 and 3.
 Since the Termination Agreement entered into force, investors have continued to raise intra-EU claims against states under the ECT. See, for example, Mainstream Renewable Power Ltd v Fed Republic of Germany, ICSID No. ARB/21/26 (registered May 13, 2021); Uniper SE v Kingdom of the Netherlands, ICSID No. ARB/21/22 (registered April 30, 2021); RWE AG v Kingdom of the Netherlands, ICSID No. ARB/21/4 (registered February 2, 2021); Encavis v Italian Republic, ICSID No. ARB/20/39 (registered October 6, 2020); Fin.Doc Srl v Romania, ICSID No. ARB/20/35 (registered September 17, 2020).
 Irrespective of whether they sign onto the Termination Agreement, there will be a strong argument that, so long as respondent states remain contracting parties to the ICSID Convention, an arbitral tribunal’s views on these issues should be decisive for a US court. See ICSID Convention, article 41(a) (‘The Tribunal shall be judge of its own competence.’). Likewise, under the New York Convention, if the arbitration agreement embodied in the relevant treaty gives the tribunal competence over its own jurisdiction, and such an award had not otherwise been set aside by the courts of the seat of arbitration, the tribunal’s jurisdictional decision likely ought also to control in the U.S. See generally First Options, 514 U.S. at 943; Chevron, 795 F.3d at 207-08.
 See Termination Agreement, preamble (‘CONSIDERING that this Agreement addresses intra-EU bilateral investment treaties; it does not cover intra-EU proceedings on the basis of Article 26 of the ECT. The European Union and its Member States will deal with this matter at a later stage.’).
