This Research Handbook focuses on the internal market aspects of the European Free Trade Association (EFTA) pillar of the European Economic Area (EEA). Leading academics, judges, and practitioners examine the EEA internal market in a structured and systematic manner. Throughout, they provide an in-depth analysis of the free movement and horizontal aspects of the EFTA pillar of the EEA. Contributing authors in this Research Handbook firstly address the free movement of goods, persons (including workers and social security), services, establishment, capital and payments within the EFTA pillar. Secondly, they dissect the flanking policies that apply, including competition, state aid, banking, insurance, transport, intellectual property, consumer protection, and the environment. Third, the Research Handbook contains a number of critical reflections. Overall, it is a comprehensive examination based on EEA primary law, EEA secondary law, EFTA Surveillance Authority practice, and the EFTA Court’s case-law. The Research Handbook on EEA Internal Market Law, providing authoritative and informative coverage, is essential reading for academics, judges, and students in all areas of European law across both the EU and EFTA pillars of the EEA. It is also a valuable resource for national and international civil servants, law firms, national courts, domestic policymakers, and private practitioners.
