The never ending story of international arbitration. The role of the CJEU in investment matters

Abstract: The history of international arbitration in recent years has focused on and found its basis in the jurisprudence of the Court of Justice of the European Union in the matter of investments. The latest cases reported with two common elements, namely the resolution of a dispute through arbitration and the preliminary ruling. The aim of this paper is to investigate these latest cases and to provide ultra-in-depth points for the future of arbitration within the context of the European Union. Is it a necessary and mandatory solution for foreign investments? Does this mean the termination of international arbitration law for member countries of the EU? The total incorporation of the rules of international law into the law of the EU through the jurisprudence of the CJEU are some of the questions that will seek to be analyzed in this work.
