On 25 July 2018, the Court of Justice of the European Union handed down a ruling on the admissibility of the request for a preliminary ruling on the validity of a Commission Decision where the applicants in the main proceedings did not bring an action for annulment against that Decision before the General Court. The judgment Georgsmarienhütte re-evaluates the interrelationship between the action for annulment and the preliminary reference procedure and is, in essence, a reiteration of the TWD doctrine established already in 1994.
