This book offers a new approach to the study of EU law of external relations.

With a view to recent developments in both the EU and the global legal order, International Law as Law of the European Union explores how, and to what extent, international law still forms part of, and plays a role in, the current legal order of the European Union.

For many observers, the European Union is mired in a deep crisis. Between sluggish growth; political turmoil following a decade of austerity politics; Brexit; and the rise of Asian influence, the EU is seen as a declining power on the world stage. Columbia Law professor Anu Bradford argues the opposite in her important new book The Brussels Effect: the EU remains an influential superpower that shapes the world in its image. By promulgating regulations that shape the international business environment, elevating standards worldwide, and leading to a notable Europeanization of many important aspects of global commerce, the EU has managed to shape policy in areas such as data privacy, consumer health and safety, environmental protection, antitrust, and online hate speech. And in contrast to how superpowers wield their global influence, the Brussels Effect - a phrase first coined by Bradford in 2012- absolves the EU from playing a direct role in imposing standards, as market forces alone are often sufficient as multinational companies voluntarily extend the EU rule to govern their global operations. The Brussels Effect shows how the EU has acquired such power, why multinational companies use EU standards as global standards, and why the EU's role as the world's regulator is likely to outlive its gradual economic decline, extending the EU's influence long into the future.

The European Union plays a significant role in international affairs. International Law and the European Union examines the impact this has had on public international law by integrating perspectives from both EU law and international law. Its analysis focuses on fields of public international law where the EU has had an influence, including customary international law, the law of treaties, international organizations, international dispute settlement, and international responsibility. International Law and the European Union shows how the EU has had a subtle but significant impact on the development of international law and how the international legal order has developed and adjusted to accommodate the EU as a distinct legal actor. In doing so, it contributes to our understanding of how international law addresses legal subjects other than States.

This book provides an analysis of key approaches to rule of law oversight in the EU and identifies deeper theoretical problems.

The principle of loyalty requires the EU and its Member States to co-operate sincerely towards the implementation of EU law. Under the principle, the European courts have developed significant public law duties on States to deepen the reach of EU law. This is the first full-length analysis of the loyalty principle and its legal implications.

This edited collection appraises the role, self-perception, reasoning and impact of the European Court of Justice on the development of European Union (EU) external relations law. Against the background of the recent recasting of the EU Treaties by the Treaty of Lisbon and at a time when questions arise over the character of the Court's judicial reasoning and the effect of international legal obligations in its case law, it discusses the contribution of the Court to the formation of the EU as an international actor and the development of EU external relations law, and the constitutional challenges the Court faces in this context. To what extent does the position of the Court contribute to a specific conception of the EU? How does the EU's constitutional order, as interpreted by the Court, shape its external relations? The Court still has only limited jurisdiction over the EU's Common Foreign and Security Policy: why has this decision been taken, and what are its implications? And what is the Court's own view of the relationship between court(s) and foreign policy, and of its own relationship with other international courts? The contributions to this volume show that the Court's influence over EU external relations derives first from its ability to shape and define the external competence of the EU and resulting constraints on the Member States, and second from its insistence on the autonomy of the EU legal order and its role as 'gatekeeper' to the entry and effect of international law into the EU system. It has not - in the external domain - overtly exerted influence through shaping substantive policy, as it has, for example, in relation to the internal market. Nevertheless the rather 'legalised' nature of EU external relations and the significance of the EU's international legal commitments mean that the role of the Court of Justice is more central than that of a national court with respect to the foreign policy of a nation state. And of course its decisions can nonetheless be highly political.

Despite their many obvious interconnections, EU and international law are all too often studied and practised in different spheres. While it is natural for each to insist on its own unique characteristics, and in particular for the EU to emphasise its sui generis nature, important insights might be lost because of this exclusionary approach. This book aims to break through some of those barriers and to show how more interaction between the two spheres might be encouraged. In so doing, it offers a constitutional dimension but also a substantive one, identifying policy areas where EU and international law and their respective actors work alongside each other. Offering a 360-degree view on both EU and international institutional and substantive law, this collection presents a refreshing perspective on a longstanding issue.
