The European Court of Justice (ECJ) has been asked by a Dutch court (in case C-429/07) to rule upon the scope of the European Commission's role as "amicus curiae" or a "friend to the court" in a case involving EU competition law. The questions arose in the context of a claim for a tax deduction for a cartel fine in the Netherlands. On 5 March 2009, Advocate General Mengozzi gave his Opinion to the ECJ on the question of whether the Commission's amicus curiae role is limited to cases involving the application of Articles 81 & 82 EC Treaty or whether it also extends to broader questions of EC competition law. In his Opinion, the Advocate-General took the view that the Commission's role did extend to observations on broader questions, such as whether tax deductions may be permitted for payment of a fine.
