Legal Requirements for the EU-Turkey Refugee Agreement: A Reply to J. Hathaway

There are many open questions and objections against the EU-Turkey deal on an agreement whose details are yet to be negotiated to manage the Syrian refugee crisis. In particular on the reciprocity part: could the agreement as an easily available tool by Turkey to blackmail visa liberalization and progress in the EU Accession negotiations? How will the EU make sure the proper treatment of all returnees? How is the resettlement of refugees from Syria to the EU (and to Germany) going to take place? James Hathaway on this blog has listed three legal requirements for the agreement to be legal. In my view none of these are likely to block an agreement.
