A. PARTIES TO A TREATY.

This Oxford Handbook examines the sources of international law, how the understanding of sources changed throughout the history of international law; how the main legal theories understood sources; the relationship between sources and the legitimacy of international law; and how sources differ across the various sub-areas of international law.

Deals with the concept of sources of international law.

This book revisits the theory of the sources of international law from the perspective of formalism. It critically analyses the virtues of formalism, construed as a theory of law ascertainment, as a means of distinguishing between law and non-law. The theory of formalism is re-evaluated against the backdrop of the growing acceptance by international legal theorists of the blurring of the lines between law and non-law. At the same time, the book acknowledges that much international normative activity nowadays takes place outside the ambit of traditional international law and that only a limited part of the exercise of public authority at the international level results in the creation of international legal rules. The theory of ascertainment that the book puts forward attempts to dispel some of the illusions of formalism that accompany the traditional sources of international law. It also sheds light on the tendency of scholars, theorists, and advocates to deformalize the identification of international legal rules with a view to expanding international law. The book seeks to revitalize and refresh the formal identification of rules by engaging with some tenets of the postmodern critique of formalism. As a result, the book not only grapples with the practice of law-making at the international level, but it also offers broad theoretical insights on international law, dealing with the main schools of thought in legal theory (positivism, naturalism, legal realism, policy-oriented jurisprudence, and postmodernism). This paperback edition features the author's discussion of this book on the EJIL Talk blog.

An account of how the practice of interpretation makes international law, drawing specific attention to the increasing authority of international courts and institutions, this book analyses the role that the language plays in shaping international law. It addresses the key issue of how it contributes to the evolution of international norms.

A collection of essays on the various aspects of the legal sources of international law, including theories of the origin of international law, explanation of its binding force, normative hierarchies and the relation of international law and politics.

The Oxford Handbook of Jurisdiction in International Law provides an authoritative and comprehensive analysis of the concept of jurisdiction in international law. Jurisdiction plays a fundamental role in international law, limiting the exercise of legal authority over international legal subjects. But despite its importance, the concept has remained, until now, underdeveloped. Discussions of jurisdiction in international law regularly refer to classic heads of jurisdiction based on territoriality or nationality, or use the SS Lotus decision of the Permanent Court of International Justice as a starting point. However, traditional understandings of jurisdiction are facing new challenges. Globalization has increased the need for jurisdiction to be applied extraterritorially, non-State forms of law provide new theoretical challenges and intersections between different forms of jurisdiction have become more intricate. This Handbook provides a necessary re-examination of the concept of jurisdiction in international law through a thematic analysis of its history, its contemporary application, and how it needs to adapt to encompass future developments in international law. It examines some of the most contentious elements of jurisdiction by considering how the concept is being applied in specific substantive and institutional settings.

This book provides a comprehensive analysis of an often neglected, misunderstood and maligned source of international law. Article 38(1)(c) of the Statute of the International Court of Justice sets out that the Court will apply the 'general principles of law recognized by civilized nations'. This source is variously lauded and criticised: held up as a panacea to all international law woes or denied even normative validity. The contrasting views and treatments of General Principles stem from a lack of a model of the source itself. This book provides that model, offering a new and rigorous understanding of Article 38(1)(c) that will be of immense value to scholars and practitioners of international law alike. At the heart of the book is a new tetrahedral framework of analysis - looking to function, type, methodology and jurisprudential legitimacy. Adopting an historical approach, the book traces the development of the source from 1875 to 2019, encompassing jurisprudence of the Permanent Court of International Justice and the International Court of Justice as well as cases from international criminal tribunals, the International Criminal Court and the World Trade Organisation. The book argues for precision in identifying cases that actually apply General Principles, and builds upon these 'proper use' cases to advance a comprehensive model of General Principles, advocating for a global approach to the methodology of the source.

This book addresses the disparity between positive non-treaty law and its scholarly assessment in the area of moral concepts, understood as altruistic as opposed to reciprocal legal obligations. It shows how scholars are generously willing to assert the existence of a rule of international law, thereby moving further away from actual state practice, not taking into account the factors of legal rhetoric and the core survival interests of the state in the formation of custom and general principles of law. The main argument is that such moral concepts can simply not manifest themselves as non-treaty sources of international law from a dogmatic perspective. The reason is the inherent connection between the formation of the non-treaty sources of international law and state interest that makes it difficult, if not impossible, to assess state practice or opinio juris in the case of altruistic obligations. The book further demonstrates this finding by looking at two cases in point: Human rights and humanitarian exceptions to the prohibition of force. As opposed to the majority of existing works on the subject, State Interest and the Sources of International Law takes a bigger-picture approach to a number of distinct problems in international law scholarship by looking at the building blocks of international relations on the one hand, and merging this with sources doctrine on the other. It will be of interest to researchers, academics, and students in the fields of international law, human rights, international relations, political science, legal philosophy, and legal theory.

Every State has an obligation to prevent terrorist attacks emanating from its territory. This proposition stems from various multilateral agreements and UN Security Council resolutions. This study exhaustively addresses the scope of this obligation of prevention and the legal consequences flowing from its violation, so as to provide greater clarity on governments' counterterrorism duties and to enhance State accountability for preventable wrongs. It defines the contents and contours of the obligation while placing critical emphasis on the mechanics of State responsibility. Whether obscured by new technologies like the Internet, the sophisticated cellular structure of some terrorist organisations or convoluted political realities, the level of governmental involvement in terrorist activities is no longer readily discernible in every instance. Furthermore, the prospect of governments waging surrogate warfare through proxies also poses intractable challenges to the mechanism of attribution in the context of State responsibility. This monograph sets out the shortcomings of the extant scheme of State responsibility while identifying a paradigm shift towards more indirect modes of accountability under international law, a trend corroborated by recent State and institutional practice. Drawing on varied legal and theoretical influences, the study devises and prescriptively argues for the implementation of a strict liability-inspired model grounded in the logic of indirect responsibility with a view to enhancing State compliance with counterterrorism obligations. This shifts the policy focus squarely to prevention, while promoting multilateralism and transnational cooperation. Ultimately, the legal and policy sensibilities underlying the book converge into a new theory of prevention in counterterrorism contexts. From the Foreword by Judge Bruno Simma, International Court of Justice "Even if one might disagree with the bases on which the author constructs his argument, the execution of the argument is solid and thorough. The coverage of the major policy arguments and the available legal source materials is equally impressive. Moreover, the author's positions are genuinely progressive and present a fairly innovative solution, in the form of a strict liability mechanism...It behoves all scholars and practitioners of international law with an interest in combating international terrorism to consider the proposals outlined in this book." Transnational Terrorism and State Accountability by Vincent-Joël Proulx has been awarded the 2014 Myres McDougal Prize for best book in Law, Science, and Policy from the Society of Policy Scientists.
