Abstract
The article comments - in a broader context - on the judgment of the Court of Justice of the EU of 6 March 2018 in case Achmea, in particular from the point of view of international law governing investment protection and investor-State dispute settlement (ISDS). In view of the limited scope of the contribution, it will focus on the case and its implications for the intra-EU bilateral investment treaties (BIT), that means the agreements between EU Member States concluded before the accession of new members to the EU.
The article does not analyze, however, a new system of dispute settlement (ICS), introduced by the EU into the CETA and other negotiated EU agreements on free trade and investment with third countries.
