The Dublin Regulation, which came into force in 2003, provides the criteria to establish which Member State is responsible for examining an asylum claim. The main principle is that the Member States which allows an asylum seeker to enter the EU (whether legally or illegally) is responsible for deciding his claim. The European Court of Human Rights has recently ruled that Belgium should not have expelled an asylum seeker to Greece under the so-called Dublin Regulation. The asylum seeker had entered the EU from Greece. In accordance with the EU's 'Dublin II' Regulation, the Belgian authorities submitted a request for the Greek authorities to deal with the asylum claim.
