Article 145U.K.
If the Commission considers that a person or undertaking has committed an infringement of this Treaty to which the provisions of Article 83 do not apply, it shall call upon the Member State having jurisdiction over that person or undertaking to cause sanctions to be imposed in respect of the infringement in accordance with its national law.
If the State concerned does not comply with such a request within the period laid down by the Commission, the latter may bring an action before the Court of Justice of the European Union to have the infringement of which the person or undertaking is accused established.
