Steve Peers' seminal text on the Justice and Home Affairs law of the European Union appears in its fifth edition, providing a detailed examination of EU legislation and case law on the issues of immigration, asylum, visas, border controls, and police and criminal law cooperation, discussing the impact and ongoing development of EU law in these complex and controversial areas. EU Asylum and Immigration Law includes discussion of the law relating to qualification as a refugee or other forms of protection, family reunion, expulsion and readmission, immigration detention, treatment of asylum seekers (including the Dublin rules allocating asylum seekers between Member States), the Schengen rules on borders, EU security databases, Frontex, labour migration, admission of students, researchers, and trainees, and obtaining long-term residence status. EU Criminal Law, Policing, and Civil Law includes discussion of Europol, Eurojust, the European Public Prosecutor, fair trials laws (including access to a lawyer, the presumption of innocence, and in absentia trials), the European Arrest Warrant, the European Investigation Order, transfer of prisoners, EU rules on double jeopardy, exchange of policing information, interception of telecoms, and cross-border cooperation on civil cases, including family law, conflict of laws and areas such as insolvency and inheritance law. Updated to include a significant volume of new case law and legislation between 2015 and 2023, it fully covers the impact of the UK leaving the EU, examining the EU's relations in this field with the UK post-Brexit - as well as the EU's relationship in this field with other non-EU countries. This edition is the definitive guide to these complex, controversial and fast-developing areas of EU law and will be invaluable to scholars, practitioners, and students in the field.
