In its ruling in the Skerdjan Celaj case (C-290/14), rendered on 1st October 2015, the Court of Justice of the European Union (CJEU) addressed once again the relation between immigration and criminal law and in particular the compatibility of national penal measures imposed as a punishment for irregular migration with the EU Returns Directive. In the previous cases touching upon this issue, the Court assessed whether the Directive allowed states to penalize non-compliance with a return order or irregular stay itself with imprisonment (El Dridi and Achughbabian, respectively) and with home detention (Sagor) as a criminal law penalty (as distinct from administrative law detention, which is expressly regulated by the Directive).
