European Union – Freedom of movement. Article 17(1) of Regulation (EU) No 604/2013 should be interpreted as meaning that the fact that a member state, designated as 'responsible' within the meaning of that regulation, had notified its intention to withdraw from the EU in accordance with art 50 of the Treaty on the European Union did not oblige the determining member state to itself examine, under the discretionary clause set out in art 17(1), the application for protection at issue. The Court of Justice of the European Union so held, among other things, in proceedings between the applicants and the International Protection Appeals Tribunal (Ireland) and others concerning the decision to transfer them to the UK under that regulation.
