In response to a climate in which respect for international law and the law of the European Union is rapidly losing ground, Paul Gragl advocates for the revival of legal monism as a solution to potentially irresolvable normative conflicts between different bodies of law. In this first comprehensive monograph on the theory as envisaged by the Pure Theory of Law of the Vienna School of Jurisprudence, the author defends legal monism against the competing theories of dualism and pluralism. Drawing on philosophical, epistemological, legal, moral, and political arguments, this book argues that only monism under the primacy of international law takes the law and the concept of legal validity seriously. On a practical level, it offers policy-makers and decision-makers methods of dealing with current problems and a means to restore respect for international law and peaceful international relations. While having the potential to revive and elicit further interest and research in monism and the Pure Theory of Law, the comprehensiveness and scope of the book also make it a choice text for inter-disciplinary scholars.

In this first full-length study of legal monism, Paul Gragl advocates for the revival of legal monism as a solution to normative conflicts between different bodies of law. Using comprehensive and inter-disciplinary arguments, this book defends the theory against dualism and pluralism.

By showing how Kelsen's theory of law works alongside his political philosophy, the book shows the Pure Theory to be part of a wider attempt to understand how political power can be legitimately exercised in pluralist societies.

Giving an overview of the current state of the law and practice in relation to treaties, this edited work is an essential reference for practitioners and legal advisers involved in treaty negotiations or the interpretation of treaties. It also reflects on the current areas of disagreement or ambiguity.

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.

Spinoza believed that there was only one substance in reality, which he called 'God or nature'. A number of leading contemporary philosophers have defended monism, this strange and beautiful idea that the cosmos is the source of all being. This book explores both the historical roots of the monism in Spinoza, and its flowering in the 21st century.

This book examines how national law is treated in WTO law, both in the WTO treaty and dispute settlement cases. The WTO treaty contains a set of far-reaching obligations establishing a systemic and constitutional framework of interaction between WTO law and national law. WTO dispute settlement operates as an international layer of judicial review of national laws and administrative, judicial or quasi-judicial measures. Consequently, much of the WTO dispute settlement decisions and rulings relate in different ways to Members' national laws. Yet, up until the publication of this book, there was no systematic analysis of this vastly important subject. This book provides a thorough map of an increasingly complex field. In doing so, it extends the enquiry beyond well-known formulas and combines practical analysis with principled discussion of how the treatment of national law in international law can and should ensure effectiveness of international rules and promote good governance within nation-states.
