L’effetto della sentenza della Corte di Giustizia dell’Unione nella causa C-284/16 “Achmea” sulle procedure arbitrali di risoluzione delle controversie intra-UE pendenti in esecuzione del Trattato sulla Carta dell’energia

The paper analyzes the recent decision of the Court of Justice of the European Union “Achmea” established that the arbitration clauses contained in investment agreements are in- compatible with EU law. The Achmea case concerned the compatibility of the Czech Repu- blic-Netherlands bilateral investment treaty (BIT) with EU law, but the Court of Justice’s reasoning should be expanded to the intra-EU investment disputes under the ECT. Conse- quently, Member States have an obligation to terminate not only intra-EU BITs, but also intra- EU application of ECT in order to ensure legal certainty.
