European Union – Public procurement. The European Court held that the principle of equal treatment of economic operators meant that a contracting entity was not in breach of that principle where it permitted one of two operators who formed part of a group of undertakings that had been invited to submit tenders by that contracting entity, to take the place of that group following the group's dissolution, provided that the economic operator by itself met the requirements and that the continuation of its participation in that procedure did not mean that other tenderers were placed at a competitive disadvantage.
