The Achmea judgment revolutionised intra-EU investment protection by declaring intra-EU bilateral investment treaties (intra-EU BITs) incompatible with EU law. This incisive book investigates whether intra-EU foreign investments benefit from this alteration, which discontinued the parallel applicability of intra-EU BITs and EU law in the EU internal market. In addition to comparative legal analysis from an investor perspective, Dominik Moskvan puts forward a proposal for a creation of a permanent intra-EU foreign investment court to ensure a balanced economic development of the EU internal market.
