What is international law, and how does it work? This book argues that our answers to these fundamental questions are shaped by a variety of social cognition and knowledge production processes. These processes act as invisible frames, through which we understand international law. To better conceive the frames within which international law moves and performs, we must understand how psychological and socio-cultural factors affect decision-making in an international legal process. This includes identifying the groups of people and institutions that shape and alter the prevailing discourse in international law, and unearthing the hidden meaning of the various mythologies that populate and influence our normative world. With chapters from leading experts in the discipline, employing insights from sociology, psychology, and behavioural science, this book investigates the mechanisms that allow us to apprehend and intellectually represent the social practice of international law. It unveils the hidden or unnoticed processes by which our understanding of international law is formed, and helps readers to unlearn some of the presuppositions that inform our largely unquestioned beliefs about international law.

This innovative edited collection uncovers the invisible frames which form our understanding of international law. Taking an interdisciplinary approach, it investigates how social cognition and knowledge production processes affect decision-making, and inform unquestioned beliefs about what international law is, and how it works.

Will appeal to scholars, practitioners and general readers engaging with treaty interpretation at all levels and will enhance the reader's knowledge and mastery of the interpretive process. It will shed light on all those relevant elements and/or connections that the traditional rule-based approach to treaty interpretation largely overlooks.

A reader-friendly overview of leading theoretical approaches to international law for students, scholars, and practitioners.

This innovative book extensively probes and reveals the existence of legal fictions in international law, developing a theory of their effectiveness and legitimacy. Reece Lewis argues that, since legal fictions exist in all systems and types of law, international law is no different and deserves discrete, detailed examination.

Along with treaties, custom is one of the sources of international law. It is known to consist of two elements: state practice and opinio juris. While many studies have looked at traditional questions of how to identify customary law, this book takes a new and original approach. It looks instead at the structure of thought that lies beneath the arguments about customary international law. By examining these structures, the book uncovers surprising conclusions, and demonstrates what the author describes as the 'discursive splendour' of customary international law. The book guides the reader through an analysis of eight distinct performances at work in the discourse on customary international law. One of its key claims is that customary international law is not the surviving trace of an ancient law-making mechanism that used to be found in traditional societies. Indeed, as is shown throughout, customary international law is anything but ancient, and there is hardly any doctrine of international law that contains so many of the features of modern thinking. It is also argued that, contrary to mainstream opinion, customary international law is in fact shaped by texts, and originates from a textual environment. This book provides an engaging account of customary international law, whilst challenging readers to rethink their understanding of this fundamental part of the discipline.

Shifts across the corpus of international law have brought the international legal system into a closer alignment with the interests of the individual. This has led to a great and growing interest in the roles and status of individuals in international law, and provided new impulses for debate. The Individual in International Law is an exploration of what is described as the humanisation of international law. It examines how international law has accommodated individuals, and how individual status, rights, and obligations have become denser and more important in the international legal system. Split into two parts, the book analyses the humanisation of international law in different historical periods and from various theoretical perspectives. The first part focuses on the historical evolution of international law, exploring how the interests of individuals have shaped the development of the legal system from antiquity to 1945, providing a counterpoint to State-centric readings of international law's history. The second part contains theoretical debates, critical approaches, and interdisciplinary investigations, offering perspectives from ius positivism and ius naturalism, Marxism, TWAIL, feminism, global law, global constitutionalism, law and economics, and legal anthropology. The book aims to stimulate further research on the humanisation and dehumanisation of new fields ranging from the ius contra bellum to climate law. The editors' introduction and conclusion frame the contributions, draw together their findings, and address critiques comprehensively. Written by a team of acknowledged experts in their fields, this volume elucidates how the interests, rights, obligations, and responsibilities of individuals have shaped international norms and regimes, and suggests how a reoriented transformative humanism can inform and develop international law in an era of profound ideological, ecological, and technical challenge.
