InfoMigrants By Emma Wallis Published on : 2021/02/24 The policy of migrant returns between EU countries is complex and creates "blurred lines," an expert in EU law and migration has told InfoMigrants. In the light of two recent cases of returns from Austria to Hungary, we decided to take a closer look at the subject. It started with two cases highlighted by the Hungarian Helsinki Committee (HHC) in December 2020 and January 2021. They were just two of several thousand cases HHC documented, but since they involved migrant returns from Austria to Hungary and then to Serbia, InfoMigrants wanted to understand the mechanism of returns within the EU.
