<h3>Achmea and Komstroy are not binding for the Federal Supreme Court</h3>
<h3>I. Introduction</h3>
In a landmark decision dated April 3, 2024 (4A_244/2023<a href="#_ftn1" name="_ftnref1">[1]</a>), the Swiss Federal Supreme Court has decided the question of whether Swiss-seated arbitral tribunals have jurisdiction over intra-EU investment disputes – an issue which has been controversial in recent years, in particular in light of the case law of the Court of Justice of the European Union (CJEU), according to which arbitral tribunals seated in the European Union (EU) lack jurisdiction over such disputes.
The arbitration underlying the Federal Supreme Court&#8217;s decision had been introduced in 2016 by a French electricity company against the Kingdom of Spain (Spain) before an hoc arbitral tribunal on the basis of the Energy Charter Treaty (ECT) against certain tariff changes introduced by Spain in the renewable energy sector. In its award dated April 11, 2023 (Award), the arbitral tribunal held in favor of the French investor and condemned Spain to pay damages for breach of its fair and equitable treatment obligation under the ECT.
Spain raised several grounds of annulment in its request to set aside the Award, none of which withstood the scrutiny of the Federal Supreme Court. Of most interest is the argument raised by Spain concerning the jurisdiction of the arbitral tribunal, and in particular the allegation that the arbitration clause contained in Article 26 of the ECT,<a href="#_ftn2" name="_ftnref2">[2]</a> a multilateral treaty signed inter alia by Spain, France and the EU, was not applicable to so-called intra-EU disputes, i.e., disputes between an EU member state and an investor from another EU member state. On the basis of the case law of the CJEU, Spain argued that the arbitral tribunal lacked jurisdiction to hear such disputes.
In its decision, the Federal Supreme Court rejected Spain&#8217;s arguments and confirmed the jurisdiction of the arbitral tribunal. Applying the rules of interpretation of the <a href="https://legal.un.org/ilc/texts/instruments/english/conventions/1_1_1969.pdf" target="_blank" rel="noopener">Vienna Convention on the Law of Treaties of 1969</a> (Vienna Convention), the Federal Supreme Court held that the ECT did not exclude intra-EU disputes from the scope of the arbitration clause in Article 26 of the ECT and that the arbitral tribunal had thus correctly declared itself competent. It also held – in no unclear terms – that the CJEU&#8217;s rulings on the incompatibility of arbitration clauses in intra-EU disputes were not binding on the Federal Supreme Court and that no particular weight should be attached to them.
Amongst the recent spate of anti-investment arbitration decisions taken by the EU institutions, the Federal Supreme Court&#8217;s decision must be hailed as a bold pro-arbitration stance confirming its unwavering support for arbitration and Switzerland&#8217;s position as a pro-arbitration jurisdiction.
<h3>II. Background of the decision: (No) investor-state dispute settlement in Europe</h3>
Before delving into the details of the decision of the Federal Supreme Court, it is worth summarizing two recent decisions of the CJEU, which significantly limit the jurisdiction of arbitral tribunals seated in the EU in connection with intra-EU investment disputes, on which Spain relied in its request to set aside the Award:
<ul>
<li>The Achmea decision is a landmark case decided by the CJEU on March 6, 2018 (<a href="https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A62016CJ0284" target="_blank" rel="noopener">Slovak Republic v. Achmea BV (Case C-284/16</a>). This decision has had profound implications for investment arbitration within the EU, particularly concerning the compatibility of investor-state dispute settlement mechanisms with EU law. The case arose from a dispute between Achmea, a Dutch insurer, and the Slovak Republic. Achmea had made investments in the Slovak health insurance market. However, after the Slovak Republic reversed its liberalization of the health insurance market, Achmea initiated arbitration proceedings under the Netherlands-Slovakia Bilateral Investment Treaty (BIT), claiming that the reversal had harmed its investments. An arbitral tribunal, seated in Germany found in favor of Achmea and awarded it damages. The Slovak Republic challenged the award before the German courts, arguing that the arbitration clause in the BIT was incompatible with EU law. The matter was referred to the CJEU for a preliminary ruling. The CJEU held that the arbitration clause in the Netherlands-Slovakia BIT, i.e., an intra-EU BIT, was indeed incompatible with EU law. The court reasoned that such clauses could prevent disputes involving EU law from being resolved by the courts of the member states and could also affect the autonomy and effectiveness of EU law. The decision effectively meant that arbitration clauses in intra-EU BITs are not enforceable within the legal order of the EU.</li>
<li>On September 2, 2023, the CJEU handed down the Komstroy decision (<a href="https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX%3A62019CJ0741" target="_blank" rel="noopener">Republic of Moldova v. Komstroy LLC (Case C-741/19</a>), which is another significant ruling concerning the compatibility of investment arbitration agreements with EU law. This decision built upon the principles established in the Achmea ruling and further clarified the impact of EU law on investment arbitration clauses. Komstroy, a Ukrainian company, sought to enforce an arbitral award against the Republic of Moldova (en passant, a non-EU member state) under the ECT. The dispute related to an alleged breach of the fair and equitable treatment standard under the ECT. The Paris Court of Appeal referred several questions to the CJEU, including whether the ECT&#8217;s arbitration clause at Article 26 was compatible with EU law when applied to intra-EU disputes. The CJEU concluded that the arbitration clause in the ECT could not be applied to intra-EU disputes. The court emphasized that the arbitration clause, if applied within the EU, could prevent the full effectiveness of EU law by depriving the national courts of the EU member states of their jurisdiction to adjudicate such disputes.</li>
</ul>
Both the Achmea and Komstroy decisions underscore the CJEU&#8217;s stance on the primacy of EU law over international agreements with regard to intra-EU investment disputes. These decisions have led to significant debate and have had a considerable impact on the practice of international investment arbitration within the EU, particularly affecting the enforcement of investment awards and the structuring of investment protection.
<h3>III. The Federal Supreme Court rejects the Achmea and Komstroy decisions and upholds the jurisdiction of an arbitral tribunal seated in Switzerland to hear intra-EU investment disputes</h3>
In its recent decision, the Federal Supreme Court had to decide whether Article 26 ECT was incompatible with EU law, thus depriving Swiss-seated arbitral tribunals of their jurisdiction over intra-EU investment claims.
As a starting point, the Federal Supreme Court recalls in its decision that the present dispute is part of a broader context concerning the very legality of recourse to investment arbitration within the EU for the settlement of intra-EU investment disputes. According to the Federal Supreme Court, for several years now, EU bodies have been crusading against international investment arbitration, in particular through the Achmea and Komstroy decisions. According to the Federal Supreme Court, the decisions handed down by the CJEU, and in particular the Komstroy ruling, are not binding on a state court called upon to rule on an annulment request against an award made by an arbitral tribunal seated in Switzerland. Without mincing its words, the Federal Supreme Court found that it accords no value to these decisions, dismissing them as pro domo positions taken by the supreme European jurisdiction (cons. 6.5).
Accordingly, the Federal Supreme Court held that it would proceed with its own interpretation of Article 26 of the ECT, which, like any other treaty, must be interpreted in good faith, in accordance with the ordinary meaning to be given to the terms of the treaty in their context, its object and purpose, and, although not expressly mentioned in Article 31 of the Vienna Convention, the principle of good faith (cons. 7.7.1). The Federal Supreme held that – interpreted in good faith – the term «unconditional» as contained in Article 26(3) of the ECT means that consent to arbitration is expressed without the slightest reservation and is therefore unrestricted. According to the Federal Supreme Court, there is nothing in the text of Article 26 of the ECT to suggest that the scope of the «unconditional consent» to arbitration is subject to other limits and does not cover disputes of an intra-European nature (cons. 7.7.1). The Federal Supreme Court also recalls that the ECT aims to promote international cooperation and investments in the energy sector – and this, without making any geographical distinction as to the origin of investors – in order to serve the ultimate cause of energy security. According to the Federal Supreme Court, granting investors based in an EU member state the right to initiate arbitration proceedings against another member state undoubtedly helps to achieve this goal (cons. 7.3).
The Federal Supreme Court also dismissed Spain&#8217;s argument relating to the relevance of the <a href="https://finance.ec.europa.eu/publications/declaration-member-states-15-january-2019-legal-consequences-achmea-judgment-and-investment_en" target="_blank" rel="noopener">declaration of 22 EU member states of January 15, 2019 on the legal consequences of the Achmea judgment and on investment protection</a> (Declaration) because it was not formulated by all contracting parties to the ECT, but only by certain (and not even all) EU member states. Thus, according to the Federal Supreme Court, the Declaration could not be regarded as a subsequent agreement between the parties concerning the interpretation of the ECT within the meaning of Article 31 of the Vienna Convention. The Federal Supreme Court also held that a closer look at the Declaration confirms that, in reality, it was not intended to interpret the provisions of the ECT, but only to clarify the legal consequences of the Achmea ruling, which had nothing to do with the ECT (cons. 7.5).
Finally, the Federal Supreme Court was not persuaded by Spain&#8217;s argument that the provisions of EU treaties should take precedence over Article 26 of the ECT in intra-European disputes, based on Article 31(3)(c) of the Vienna Convention. According to Spain, EU treaties, as interpreted by the CJEU, conflict with the ECT and thus invalidate consent to arbitration under the ECT. However, since Spain introduced new legal considerations regarding Articles 30 and 41 of the Vienna Convention only in its rebuttal submission in the set-aside proceedings, these were considered belated and thus inadmissible. Notwithstanding this, the Federal Supreme Court considered that even if they had been admissible, Spain&#8217;s allegations in this regard would not have prospered (cons. 8.1).
Therefore, the Federal Supreme Court rejected the objection of lack of jurisdiction raised by Spain and confirmed the jurisdiction of the arbitral tribunal to adjudicate an intra-EU investment dispute on the basis of Article 26 of the ECT.
<h3>IV. Conclusion</h3>
The decision of the Federal Supreme Court is ground-breaking in so far as it confirms that the anti-investment arbitration position taken by the EU and its various institutions will be confined within the boundaries of the EU and will not spill over, at least not in Switzerland, where arbitration agreements validly concluded, whether in a bilateral or multilateral investment agreement will continue to apply in full force. Thus, for investors contemplating intra-EU investments, dispute resolution by Swiss seated arbitral tribunals remains a safe option.

Switzerland stops the EU's «crusade against investment arbitration»

Im vorliegenden Fall hatte ein Schiedsgericht dem Kläger/Arrestgläubiger in einem Schiedsspruch nach dem Übereinkommen zur Beilegung von Investitionsstreitigkeiten zwischen Staaten und Angehörigen anderer Staaten vom 18. März 1965 (ICSID-Übereinkommen) bestimmte Geldbeträge zugesprochen. Der Kläger/Arrestgläubiger versuchte, den ICSID-Schiedsspruch gegen den ausländischen Staat in der Schweiz zu vollstrecken, und beantragte die Verarrestierung mehrerer sich in der Schweiz befindlicher Vermögenswerte des ausländischen Staates, unter anderem Bankkonten, Immobilien, Marken und Patente, im Rahmen eines Arrests gemäss Art. 271 des Bundesgesetzes über Schuldbetreibung und Konkurs (SchKG).
In diesem Zusammenhang bestätigte das Bundesgericht, dass ein Arrest gemäss Art. 271 Abs. 1 Ziff. 6 nicht voraussetzt, dass der Arrestgläubiger vorab einen definitiven Entscheid über die Anerkennung und Vollstreckbarkeit des ICSID-Schiedsspruchs erwirkt. Vielmehr ist ausreichend, wenn der Arrestgläubiger im Arrestverfahren glaubhaft macht, dass der Anerkennung und Vollstreckung seines Titels dem ersten Anschein nach nichts entgegensteht. Zu letzterem Erfordernis stellte das Bundesgericht fest, dass nach Art. 54 Abs. 1 ICSID-Übereinkommen jeder Vertragsstaat verpflichtet ist, jeden im Rahmen des ICSID-Übereinkommens erlassenen Schiedsspruch als bindend anzuerkennen und für die Vollstreckung der darin auferlegten finanziellen Verpflichtungen in seinem Hoheitsgebiet zu sorgen so, als handle es sich um ein rechtskräftiges Urteil eines seiner innerstaatlichen Gerichte. Gemäss Art. 54 Abs. 2 ICSID-Übereinkommen muss die betroffene Partei lediglich eine vom ICSID-Generalsekretär beglaubigte Kopie des Schiedsspruchs vorlegen, um die Anerkennung und Vollstreckung des Schiedsspruchs im Hoheitsgebiet eines Vertragsstaates zu erwirken. Das Bundesgericht stellte daher fest, dass gemäss Art. 54 Abs. 1 und 2 ICSID-Übereinkommen vor der Vollstreckung nur eine Prüfung der Echtheit des Schiedsspruchs erfolgen kann, nicht aber eine Überprüfung des Schiedsspruchs auf allgemeine Anerkennungsvoraussetzungen; insbesondere ist auch eine Ordre public-Kontrolle verwehrt. Um eine Verarrestierung von Vermögenswerten auf der Grundlage eines ICSID-Schiedsspruchs zu erwirken, muss der Arrestgläubiger also nur glaubhaft machen, dass es sich um einen echten ICSID-Schiedsspruch handelt.
Hinsichtlich der Verarrestierung von Vermögenswerten eines ausländischen Staates verwies das Bundesgericht auf seine Rechtsprechung, wonach eine solche Verarrestierung zweierlei voraussetzt: Erstens darf der fremde Staat im Rechtsverhältnis, das der Arrestforderung zugrunde liegt, nicht hoheitlich («iure imperii») gehandelt haben, sondern muss als Träger von privaten Rechten («iure gestionis») aufgetreten sein. Zweitens setzt eine Zwangsvollstreckungsmassnahme gegen einen fremden Staat auch in Fällen privatrechtlichen Handelns voraus, dass das besagte Rechtsverhältnis eine hinreichende Binnenbeziehung zum schweizerischen Staatsgebiet aufweist. Das Bundesgericht hat im besprochenen Entscheid eingehend geprüft, ob das Erfordernis einer ausreichenden Binnenbeziehung auch bei der Vollstreckung von ICSID-Schiedssprüchen gilt, die von den Vertragsstaaten für die Vollstreckung wie inländische Urteile behandelt werden müssen. Das Bundesgericht kam jedoch zu dem Schluss, dass dieses Erfordernis auch für ICSID-Schiedssprüche gilt. Es stellte fest, dass das Erfordernis einer Binnenbeziehung nicht gegen Art. 54 ICSID-Übereinkommen verstösst, und verwies auf die Lehre, wonach das Erfordernis einer Binnenbeziehung im Einklang steht mit dem Recht der Vertragsstaaten, ihr eigenes Recht auf Vollstreckungsimmunität anzuwenden (Art. 55 ICSID-Übereinkommen). Nach der Rechtsprechung liegt eine Binnenbeziehung insbesondere dann vor, wenn das Schuldverhältnis, aus dem die streitige Arrestforderung hergeleitet wird, in der Schweiz begründet wurde oder wenn es hier zu erfüllen ist oder wenn der fremde Staat in der Schweiz zumindest Handlungen vorgenommen hat, mit denen er in der Schweiz einen Erfüllungsort begründete. Hingegen genügt es nicht, dass Vermögenswerte des fremden Staates in der Schweiz gelegen sind oder die Forderung von einem Schiedsgericht mit Sitz in der Schweiz zugesprochen wurde. Ebensowenig genügt ist, dass die Forderung einem ICSID-Schiedsspruch entspringt, der für die Vollstreckung wie inländische Urteile zu behandeln ist.

Leitentscheid zur Vollstreckung von ICSID-Schiedssprüchen

On March 21, 2022, Member States of the International Center for Settlement of Investment Disputes (ICSID) approved amendments to ICSID&#8217;s rules for resolving disputes between foreign investors and host States. The amended rules come into effect on July 1, 2022.
The goal of the amendment was to draw on the lessons learnt from the over 700 ICSID proceedings conducted to date and to modernize, simplify and streamline the proceedings. Some important amendments to the ICSID Arbitration Rules address concerns relating to efficiency, costs of proceedings, greater transparency and security for costs.
The amended arbitration rules provide for greater transparency in the conduct and outcome of the proceedings through new provisions on the publication of documents and the presence of observers at the hearing. As per the amended rules, absent a clear objection within 60 days, parties will be deemed to have consented to the publication of the award. Likewise, tribunals may permit third parties, including the non-disputing treaty party, to make submissions in the proceedings. An additional feature addressing transparency includes disclosure obligations concerning third party funders that apply throughout the proceedings. Parties must now disclose the names and addresses of entities and persons from whom they are receiving funding, and if the funder is a judicial person, then the parties must also disclose who controls the funder.
The amendment also aims at reducing the environmental footprint of ICSID proceedings through the greater use of technology and less paper-intensive procedures. Under the new rules, all filings will be electronic, unless there are special reasons to maintain paper filings.
In order to streamline proceedings and make them more efficient, the amendment has introduced specific timelines for different phases of the proceedings, the most noteworthy being that awards will henceforth have to be rendered no later than 240 days after the last submission. Special procedures have also been introduced for applications to dismiss claims for a manifest lack of legal merit, bifurcation, preliminary objections and provisional measures. New provisions on expedited procedures provide that the parties to an arbitration can, at any time, consent to an expedited arbitration procedure, unless they have opted out. In the case of expedited proceedings, the award must be rendered 120 days after the hearing. The amendment also introduces a requirement that tribunals convene case management conferences at the outset to narrow the issues in dispute.
The amended rules also purport to change the current ICSID practice of requiring each party to bear their own costs by specifically stating the factors that the tribunal must take into consideration when making cost decisions. These include (a) the outcome of the proceeding or any part of it; (b) the conduct of the parties during the proceeding; (c) the complexity of the issues; and (d) the reasonableness of the costs claimed. A new provision on security for costs lays down the procedure and the factors that tribunals must consider when deciding on whether to award security for costs.
Furthermore, access to ICSID arbitration and conciliation has been broadened by granting access to the ICSID Additional Facility Rules in cases where both the claimant and the respondent state are not ICSID Contracting States or nationals of a Contracting State. Under the amended Additional Facility Rules, Regional Economic Integration Organizations, such as the European Union, may also be party to the proceedings.
New rules on mediation and fact-finding have also been added, which may be used as stand-alone procedures or in combination with arbitration proceedings.
