“Though the top EU court recently ruled that Germany, Denmark and other Schengen states have no legal basis for extending border checks reimposed in 2015, the European Commission is not initiating infringement procedures. According to the Schengen Agreement, people and goods may freely cross the borders of the 26 signatory countries without any checks or requirements. Internal border controls within the Schengen Area can only be reintroduced as a last resort in response to serious threats to domestic security.” – Deutsche Welle
