The European Convention on Human Rights and European Union law provide an increasingly important framework for the protection of the rights of foreigners. European Union legislation relating to asylum, borders and immigration is developing fast. There is an impressive body of case law by the European Court of Human Rights relating in particular to Articles 3, 5, 8 and 13 of the ECHR. The Court of Justice of the European Union is increasingly asked to pronounce on the interpretation of European Union law provisions in this field. The third edition of this handbook, updated up to July 2020, presents this European Union legislation and the body of case law by the two European courts in an accessible way.
