The relationship between international investment law (IIL) and EU law is not without problems as evidenced by the Achmea ruling. These tensions have become more evident in the Micula case in which the commission resorted to the state aid rules in order to attack arbitration awards arising from intra-EU Bilateral investment treaties (BITs) (deeming its enforcement as state aid). Despite its two rulings relating to the Micula saga, the Court of Justice of the European Union (CJEU) has not yet validated (or not) the application of state aid rules to the enforcement of intra-EU awards. Hopefully, the upcoming general court’s judgment shall rule on the merits of the Micula case thereby dispelling doubts. Nevertheless, it is foreseeable that further clarifying judgments will be required concerning the recognition and enforcement of intra-EU awards in non-EU jurisdictions. This article reviews the current situation to show that, while state aid rules could adequately prevent the enforcement of an intra-EU award within EU borders, they lack effectiveness for blocking enforcement beyond its borders.
