Since Spring 2017 asylum seekers who traveled illegally from Greece to another European country, can be send back to Greece. However in practice nearly nobody was send back in 2017. According to a statement of the Greek Asylum Service, Greece has received nearly 2.000 requests to take people back, but only accepted 68 of these requests. And just one of this 68 had so far been actually transferred to Greece. Also in October a German court had overruled a transfer decision to Greece, because in the opinion of the court the conditions in Greece do still not meet the necessary standards of the European Union. Of course this might change and nobody knows if in the future more people will be send back. In theory every person who illegally entered Greek territory after the 15th of March 2017 or who has applied for asylum in Greece after the 15th of March 2017 and continues to travel illegally to another country, can be send back to Greece.
