Immigration – Refugee. The Court of Justice of the European Union ruled that art 27(1) of European Parliament and Council Regulation (EU) 604/2013 had to be interpreted as meaning that an asylum seeker was entitled to plead, in an appeal against a decision to transfer him, the incorrect application of one of the criteria for determining responsibility laid down in Ch III of the Regulation, in particular, the criterion relating to the grant of a visa set out in art 12 of the Regulation.
