A2A SpA v Agenzia delle Entrate

European Union – State aid. The Court of Justice of the European Union gave a preliminary ruling, deciding that art 14 of Council Regulation (EC) 659/1999 and arts 11 and 13 of Commission Regulation (EC) 794/2004 did not preclude national legislation, such as that at issue in the present proceedings, which, by means of a reference to Regulation 794/2004, provided for the application of compound interest to the recovery of state aid, even though the decision declaring that aid incompatible with the common market and ordering its recovery had been adopted and notified to the member state concerned before that Regulation had entered into force.
