Over the last few years, there have been numerous complaints about extensive and particularly rigorous checks at airports in Germany and Belgium for those travelling to and from Greece, an EU Member State and a party to the Schengen Convention. This issue is of particular importance in the light of the discussions/consultations on the extension of the Schengen Treaty to other, more recent Member States of the Union. For countries such as Greece, which is severely affected and is suffering most from the consequences of the migratory and refugee crisis faced by the EU, the issue is an important priority.

In this context, can the Commission say:

How can the Commission and the EU allow the discriminatory treatment of nationals of a Member State which is a party to the Schengen Treaty?

What is, ultimately, the ‘safety net’ that the EU provides against unilateral decisions by Member States in respect of others?
