This book is a direct result of the publication of the 1994 Netherlands Yearbook of International Law, published in 1995. It was decided that the publication of the 25th Yearbook should be marked by a special volume written by current and former members of the Board of Editors, omitting the usual documentation sections. The central theme of this special volume is whether the secondary rules form a potential risk, constituting a threat to the global unity and efficacy of the international legal order. As many fields of international law as possible have been included: diplomatic law, the law of war, human rights, environmental law, and the law of international organizations (e.g. GATT/WTO and the European Communities). The research methods used are presented in an introductory paper, and results and conclusions are provided. The UN legal system is also accorded its rightful place in the research.

The proliferation of international courts and the extension of international regulation to new areas have been considered to be threatening for the unity of Public International Law as a legal system. These developments are the consequence of the increasing formation of legal subsystems (material international regimes) which continue to grow in complexity. How these trends affect the unity of the international legal system requires theoretical scrutiny of its fundamental bases. This work considers that the unity of the international legal system depends upon its normative structure, and on the social medium in which it is applied: the evolving international community. A unified international legal system has as its ultimate goal the protection of human dignity through the international regulation of human rights. The question of the unifying stability of the international legal system and the development of legal subsystems within it encourages a review of the major issues of current Public International Law, considering the evolution from traditional doctrines to recent approaches. This review is done from an analytical frame that provides a deeper understanding of the current situation of Public International Law as a legal system.

'Fragmentation' has become a defining, albeit controversial, metaphor of international law scholarship in the era of globalisation. Some scholars see it as a new development, others as history repeating itself; some approach it as a technical issue and some as the reflection of deeper political struggles. But there is near-consensus about the fact that the established vision of international law as a unitary whole is under threat. At the core of the fragmentation debate lies the concept of unity, but this is hardly ever rationalised and is more assumed than explained. Its meaning remains vague and intuitive. 'The Concept of Unity in Public International Law' attempts to dispel that vagueness by exploring the various possible meanings of the concept of unity in international law. However, eschewing one grand theory of unity, it identifies and compares five candidates. Intentionally pluralistic in its outlook, the book does not engage in normative arguments about whether international law is or should be unitary but seeks to show instead that the concept of unity is contested and that discourses on fragmentation are necessarily contingent. The thesis on which the book is based won the 2009 Prize for best doctoral thesis from the Association des professeurs de droit du Québec.

This book establishes a framework for analysis of the institutional and normative character of the WTO by locating the organization in a broader theory of international institutional law and in determining the basis for the conferral and exercise of powers in relation to its executive, legislative and adjudicative functions. The WTO is also read as an international regime in order to go beyond its formal legal and constitutional bases and to observe the Members' practice in the context of the former semi-institutionalised GATT treaty regime with which it retains strong links. WTO decision-making, which underpins and informs its institutional and normative acts, is analysed in order to better understand the dynamics of the organization. Normative developments in the WTO are reviewed from the perspective of the creation, maintenance and revision of legally binding and non-binding or 'soft' law norms, in the sense of principles, rules and standards contained in primary treaty rules, which set out the rights and obligations of the Members, and subsidiary rule-making activity by WTO bodies.

First published in 1970, Akehurst’s Modern Introduction to International Law rapidly established itself as a widely used and successful textbook in its field. Being the shortest of all the major textbooks in this area, it continues to offer a concise and accessible overview of the concepts, themes, and issues central to the growing system of international law, while retaining Akehurst’s original positivist approach that accounts for the essence and character of this system of law. This new ninth edition has been further revised and updated by Alexander Orakhelashvili to take account of a plethora of recent developments and updates in the field, accounting for over forty decisions of international and national courts, as well as a number of treaties and major incidents that have occurred since the eighth edition of this textbook was published. Based on transparent methodology and with a distinctive cross-jurisdictional approach which opens up the discipline to students from all backgrounds, this engaging, well-structured, and reputable textbook will provide students with all the tools, methods, and concepts they need to fully understand this complex and diverse subject. It is an essential text for all undergraduate and postgraduate students of international law, government and politics, and international relations. This book is one of the only textbooks in international law to offer a fully updated, bespoke companion website: www.routledge.com/cw/orakhelashvili.

This book examines the responsibility of States and international organizations for complicity (aid or assistance) in an internationally wrongful act. Despite the recognition of responsibility for complicity as a rule of customary international law by the International Court of Justice, this book argues that the effectiveness and utility of this form of responsibility is fraught with systemic and operational limits. These limits include a lack of clarity in its constituent elements, its co-existence with primary rules prohibiting complicity and the obligations of due diligence, its implementation and the underlying causal tests, its uncertain relationship to other forms of shared and indirect responsibility, and its potential as a form of attribution of conduct. This book submits that the content and elements of this form of responsibility need adjustments to respond more effectively to the phenomenon of complicity in international affairs.
