The appellants also maintain in that regard that the Court of First Instance committed an error of law in failing to recognise that the Commission is obliged to satisfy a higher standard of proof when a concentration is prohibited than when such a concentration is approved, since a prohibition represents a serious limitation of the commercial freedom of the notifying parties and since concentrations should benefit from a presumption that they are compatible with the common market.
Lisaks väidavad apellandid sellega seoses, et Esimese Astme Kohus rikkus õigusnormi, kuna ta ei tunnistanud, et komisjon peab koondumise keelamisel järgima kõrgemaid tõendamisnõudeid kui koondumise lubamisel, kuna keelamine on tõsine takistus teatanud poolte kaubandusvabadusele ning koondumistele peab kehtima ühisturuga kokkusobivuse eeldus.
