Press Release: Judgment in Case C-534/11. Mehmet Arslan v Policie ČR, Krajské ředitelství policie Ústeckého kraje, odbor cizinecké policie

An asylum seeker may, on the basis of national law, be detained for the purposes of removal on the ground of illegal stay where the application for asylum has been made with the sole aim of delaying or jeopardising enforcement of the return decision.

The national authorities must, however, examine on a case-by-case basis whether that is the case and whether it is objectively necessary and proportionate to keep the asylum seeker in detention in order to prevent him from definitively evading return.
