    Quentin Declève authors article on the consequences of the Court of Justice's judgment in Achmea

    In its judgment in Achmea, the Court of Justice of the European Union ruled that an investor-State arbitration (ISDS) clause in a bilateral investment treaty (BIT) concluded between two EU Member States is contrary to the principle of the autonomy of the EU legal order (judgment of 6 March 2018, Case C-284/16). In his article, Van Bael & Bellis associate Quentin Declève suggests that the Achmea judgment could have implications for the validity, not only of ISDS clauses in intra-EU BITs, but also of ISDS and applicable law clauses in BITs and other agreements concluded by the EU (or its Member States) with third countries. The article was published (on-line) in the European Papers and is part of a forthcoming issue dedicated to the Achmea judgment. It is accessible here.

    Opinion 1/17 on CETA: Advocate General Bot finds that the investment court system in CETA is compatible with EU law

    On 29 January 2019, Advocate General Bot delivered his long-awaited Opinion (the Opinion) on whether the investment court system (ICS) in Chapter Eight, Section F, of the European Union-Canada Comprehensive Economic and Trade Agreement (CETA) is compatible with European Union (EU) law, in particular with the autonomy of the EU legal order and fundamental rights. The next step in the proceedings before the Court of Justice of the European Union (CJEU), initiated by Belgium following complications in its ratification process, is for the CJEU to deliver its Opinion on the same question. This client alert discusses the key elements of the Opinion and the implications of these CJEU proceedings on the European Union’s common commercial policy and its policy of advocating reform of existing investor-State dispute settlement (ISDS) and the establishment of a multilateral investment court (MIC).
