By their applications, the Slovak Republic and Hungary seeks annulment of Council Decision (EU) 2015/1601 of 22 September 2015 establishing provisional measures in the area of international protection for the benefit of Italy and Greece (OJ 2015 L 248, p. 80, ‘the contested decision'). he contested decision was adopted on the basis of Article 78(3) TFEU, which provides that ‘in the event of one or more Member States being confronted by an emergency situation characterized by a sudden inflow of nationals of third countries, the Council, on a proposal from the Commission, may adopt provisional measures for the benefit of the Member State(s) concerned. It shall act after consulting the European Parliament'. Slovakia and Hungary which, like the Czech Republic and Romania, voted against the adoption of the contested decision in the Council, have asked the Court of Justice to annul the decision. In support of their actions they put forward pleas seeking to show (i) that the adoption of the decision was vitiated by errors of a procedural nature or arising from the choice of an inappropriate legal basis and (ii) that the decision was neither a suitable response to the migrant crisis nor necessary for that purpose. In the proceedings before the Court, Poland has intervened in support of Slovakia and Hungary, while Belgium, Germany, Greece, France, Italy, Luxembourg, Sweden and the Commission have intervened in support of the Council. In its judgement, the Court dismisses in their entirety the actions brought by Slovakia and Hungary. The Court also holds that the Council was not required to act unanimously when it adopted the contested decision, even though, for the purpose of adopting the above-mentioned amendments, it had to depart from the Commission's initial proposal. The Court finds that the amended proposal was in fact approved on behalf of the Commission by two of its Members, who were authorized by the College of Commissioners for that purpose.
