In response to the migration crisis that affected Europe in the summer of 2015, the Council of the European Union adopted a decision in order to help Italy and Greece deal with the massive inflow of migrants. The decision provides for the relocation from those two Member States to other EU Member States, over a period of two years, of 120 000 persons in clear need of international protection. 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.By today’s (6 September 2017) judgment, the Court dismissed in their entirety the actions brought by Slovakia and Hungary (Judgment in Joined Cases C-643/15 and C-647/15 Slovakia and Hungary v Council)
