Customary Law in the Modern World is the study of a coherent and well-established legal system, which is now operating in the context of a modern nation-state and therefore poised between remaining relevant and the threat of marginalization. Focusing on Sudan, the author places customary law in its historical and cultural context, analyzing the fundamental and traditional values that underlie customary law and the impact of the war between the North and the South that lasted intermittently for half a century. He deals with the substance of customary law, covering a wide variety of areas: family law, property law, torts and criminal liability. Drawing on interviews conducted with judges, legislators and practicing lawyers on customary law and its future in the modern context, the book challenges the development of customary law to build on the positives of tradition and the reform of its shortcomings, particularly in the areas of human rights, gender equality and the protection of children. This book fills a gap in the literature on customary law, and will be of great interest to anyone interested in law, anthropology and politics.

Some legal rules are not laid down by a legislator but grow instead from informal social practices. In contract law, for example, the customs of merchants are used by courts to interpret the provisions of business contracts; in tort law, customs of best practice are used by courts to define professional responsibility. Nowhere are customary rules of law more prominent than in international law. The customs defining the obligations of each State to other States and, to some extent, to its own citizens, are often treated as legally binding. However, unlike natural law and positive law, customary law has received very little scholarly analysis. To remedy this neglect, a distinguished group of philosophers, historians and lawyers has been assembled to assess the nature and significance of customary law. The book offers fresh insights on this neglected and misunderstood form of law.

This book promotes discussion and understanding of customary law and explores its continued relevance in sub-Saharan Africa. It considers the characteristics of customary law and efforts to ascertain and codify customary law, and how this body of law differs in content, form and status from legislation and common law.

This book seeks to re-appreciate the concept of customary international law as a form of spontaneous societal self-organisation, and to develop the methodological consequences that ensue from this conception for the practice of its application. In pursuing this aim, the author draws from three different strands of scholarship that have not yet been considered in connection with one another: First, general jurisprudential theories of customary law; second, theories of customary international law, especially as they relate to international relations scholarship; and third, methodological approaches to the interpretation of international law. This expansive, philosophical layout of the book enables the author to put the conceptual enigmas of customary international law into a broader perspective. Among the issues discussed in the book are the dichotomy of its traditional and modern forms and the respective benefits and disadvantages of inductive and deductive approaches to its ascertainment. In the course of this analysis, the author draws insights from Friedrich August Hayek’s theory of law as a ‘spontaneous order’, an information-processing device which enables the participants of a legal system to make use of decentralised knowledge. The book argues that the major advantage of custom as a source of international law lies in the fact that it is the result of a gradual process of trial and error, rather than the product of deliberate planning. This makes it a particularly apposite source of law in a time of seismic shifts in the distribution of power within a vastly diverse community of States, when a new global order is expected to emerge, the contours of which are not yet clearly discernible. This book applies general concepts of legal philosophy to explain the continuing relevance of custom as a source of international law while at the same time inferring from this theoretical framework concrete practical and methodological consequences, the most important of which is the special role that purposive interpretation plays with respect to rules of international custom. Given this broad approach, the book will be of interest to several groups of potential readers including academics interested in the philosophy of customary law in general, academic international lawyers and legal practitioners, especially judges, scholars of international relations and all those interested in how the international community of States organises itself.

"Law in Modern Society" is a comparative study of the place of law in societies as well as a criticism of social theory. Under what conditions do different kinds of law emerge? What are the bases of the rule of law ideal that marks advanced liberal, capitalist societies? What can the study of law teach us about social hierarchy and moral vision in these societies, and, indeed, about the specificity of Western civilization? Why do we find it necessary to struggle for the rule of law and impossible to achieve it? What political possibilities are closed or opened by present-day changes in the established styles of legality and legal thought? Unger deals with these questions in a broad range of historical settings. But he also relates them to the central issues of social theory: the method of explanation, the conditions of social order, and the nature of 'modern' society. the book argues that to resolve its own internal dilemmas the science of society must once again become both metaphysical and political.

This highly original work demonstrates the fundamental role of customary law for the realization of Indigenous peoples’ human rights and for sound national and international legal governance. The book reviews the legal status of customary law and its relationship with positive and natural law from the time of Plato up to the present. It examines its growing recognition in constitutional and international law and its dependence on and at times strained relationship with human rights law. The author analyzes the role of customary law in tribal, national and international governance of Indigenous peoples’ lands, resources and cultural heritage. He explores the challenges and opportunities for its recognition by courts and alternative dispute resolution mechanisms, including issues of proof of law and conflicts between customary practices and human rights. He throws light on the richness inherent in legal diversity and key principles of customary law and their influence in legal practice and on emerging notions of intercultural equity and justice. He concludes that Indigenous peoples’ rights to their customary legal regimes and states’ obligations to respect and recognize customary law, in order to secure their human rights, are principles of international customary law, and as such binding on all states. At a time when the self-determination, land, resources and cultural heritage of Indigenous peoples are increasingly under threat, this accessible book presents the key issues for both legal and non-legal scholars, practitioners, students of human rights and environmental justice, and Indigenous peoples themselves.

For many nations, a key challenge is how to achieve sustainable development without a return to centralized planning. Using case studies from Greenland, Hawaii and northern Norway, this 2006 book examines whether 'bottom-up' systems such as customary law can play a critical role in achieving viable systems for managing natural resources. Customary law consists of underlying social norms that may become the acknowledged law of the land. The key to determining whether a custom constitutes customary law is whether the public acts as if the observance of the custom is legally obligated. While the use of customary law does not always produce sustainability, the study of customary methods of resource management can produce valuable insights into methods of managing resources in a sustainable way.
