Samenvatting

Ever since the 2015 start of what is now often referred to as the European ‘migration crisis’, European member states have been struggling with one of the key fundaments of the European Union and in particular the Schengen Agreement: the principle of free movement. Whereas this principle entails that people should be able to move freely within the Schengen Area, as a result of the ongoing securitization and politicization of migration, Member States are exploring the different opportunities the Schengen Border Code allows them to monitor intra-Schengen cross-border mobility. In doing so, countries seem to have two options: either to temporarily reintroduce border controls or to – permanently – carry out police or immigration controls in an area around the border. In this article we explore and critically assess the choices various countries have made and what seems to be the position of the European Commission in all this.
