Implications of EU Court of Justice Judgment in the Fiat Case for Future State Aid Investigations

In this episode of S&C’s Critical Insights, Juan Rodriguez, Co-Head of S&C’s European Competition Group and the Firm’s Antitrust Group, and associate Marielena Doeding discuss the European Court of Justice’s ruling in the Fiat case and its implication for future state aid investigations. This landmark judgment—in which the Court of Justice annulled a General Court judgment and European Commission decision –clarified the parameters under which the Commission may investigate individual tax rulings under state aid rules. Although the judgment reaffirms that the Commission may investigate tax measures for compliance with state aid rules, in doing so, it cannot apply its own version of the arm’s length principle to tax measures; in particular, it cannot apply the arm’s length principle to tax measures in jurisdictions unless – and then only to the extent that – the law of the jurisdiction incorporates that principle. Instead, the Commission must carefully consider national tax rules to assess whether or not a measure confers a selective advantage for state aid purposes. Sullivan & Cromwell represented Fiat in this litigation.
