Jus Cogens

Peremptory Norms of General International Law (Jus Cogens): Disquisitions and Dispositions is a collection of contributions on various aspects of jus cogens in international law.

One of the most complex doctrines in contemporary international law, jus cogens is the immediate product of the socialization of the international community following the Second World War. However, the doctrine resonates in a centuries-old legal tradition which constrains the dynamics of voluntarism that characterize conventional international law. To reconcile this modern iteration of individual-oriented public order norms with the traditionally state-based form of international law, Thomas Weatherall applies the idea of a social contract to structure the analysis of jus cogens into four areas: authority, sources, content and enforcement. The legal and political implications of this analysis give form to jus cogens as the product of interrelation across an individual-oriented normative framework, a state-based legal order, and values common to the international community as a whole.

In Peremptory Norms of International Law and Terrorism (Jus Cogens) and the Prohibition of Terrorism, Aniel de Beer evaluates the role of peremptory norms of international law or jus cogens in the fight against terrorism.

Because of its unique nature, the sources of international law are not always easy to identify and interpret. This book provides an ideal introduction to these sources for anyone needing to better understand where international law comes from. As well as looking at treaties and custom, the book will look at more modern and controversial sources.

Whilst the concept of jus cogens has grown increasingly more important in public international law, lawyers remain hugely divided both over what precisely confers a jus cogens status on a norm, and what this conferral implies in terms of legal consequences. In this ground-breaking book, Ulf Linderfalk clearly and succinctly explores the reasons for this divide in order to facilitate more rational and productive future discourse.

In this volume Dinah Shelton considers jus cogens, its place in legal scholarship from Grotius to the present day, and its use in various domestic courts.

This work, the outgrowth of a joint reflection by French and German international lawyers, attempts to reconceptualize the doctrine of hierarchy in international law by emphasizing that a clear distinction should be drawn between primary rules, which encapsulate precepts for the protection of the basic values of the international community, and secondary rules, which determine the regime of legal consequences flowing from a breach of such rules of conduct.

This book offers a comprehensive analysis of the law of treaties based on the interplay between the 1969 Vienna Convention on the Law of Treaties and customary international law. Written by a team of renowned international lawyers, it offers new insight into the basic concepts and methodology of the law of treaties and its problems.

Jus cogens is a formidable yet elusive concept of international law. Since its incorporation in the Vienna Convention on the Law of Treaties some 35 years ago, it has made tentative inroads into international legal practice. But its role in international law is arguably less prominent than might have been expected on the basis of its powerful potential and in view of wider developments in international law that call for constitutionalisation and hierarchy, including the processes of fragmentation and humanization. This volume of the Netherlands Yearbook of International Law sets out to clarify the concepts and doctrines relevant to jus cogens and to sharpen the debate on its theoretical foundations, functions and legal effects. To that purpose, the volume brings together contributions on the genesis and function of jus cogens, on the application of jus cogens in specialised areas of international law and on its enforcement and legal consequences. Together, they reinforce the understanding of jus cogens as a hierarchical concept of international law and shed light on its potential for further development.

Robert Kolb, one of the leading international scholars of his generation, offers a seminal survey of the question of peremptory international law. The author analyses and systemises different questions, such as: the typology of peremptory norms beyond the Vienna Convention on the Law of Treaties; here he distinguishes between 'public order' jus cogens and mere 'public utility' jus cogens. Furthermore, what about relative jus cogens, such as regional jus cogens norms or conventional jus cogens norms? What about some consequences of jus cogens breaches in the law of State responsibility: are they themselves jus cogens? Thus, can individual war reparations be renounced by lump-sum agreements? What happens if different jus cogens norms are in conflict? Is there a difference between the scope of jus cogens in inter-State relations and its scope for other subjects of law, such as the UN and its Security Council? Is jus cogens necessarily predicated on the concept of a hierarchy of norms? What is the exact extent of the peremptory nature of some rules? Sometimes, only the core of a principle is peremptory, while its normative periphery is not. Also, in the use of force, the peremptory character of the provision is compatible with agreements falling under the recognised exceptions, such as collective self-defence. These and other unusual questions are discussed in the present book.
