International law holds a paradoxical position with territory. Most rules of international law are traditionally based on the notion of State territory, and territoriality still significantly shapes our contemporary legal system. At the same time, new developments have challenged territory as the main organising principle in international relations. Three trends in particular have affected the role of territoriality in international law: the move towards functional regimes, the rise of cosmopolitan projects claiming to transgress state boundaries, and the development of technologies resulting in the need to address intangible, non-territorial, phenomena. Yet, notwithstanding some profound changes, it remains impossible to think of international law without a territorial locus. If international law is undergoing changes, this implies a reconfiguration of territory, but not a move beyond it. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles of a conceptual nature in a varying thematic area of public international law.

This volume of the Netherlands Yearbook of International Law (NYIL) is the fiftieth in the Series, which means that the NYIL has now been with us for half a century. The editors decided not to let this moment go by unnoticed, but to devote this year’s edition to an analysis of the phenomenon of yearbooks in international law. Once the decision was made that this would be the subject of this year’s NYIL, the editors asked themselves a number of questions. For instance: Not many academic disciplines have yearbooks, so what is the reason we do? What is the added value of having a yearbook alongside the abundance of international law journals, regular monographs and edited volumes that are published on a yearly basis? Does the existence of yearbooks tell us something about who we are, or who we think we are, or what we have to contribute to the world? These questions will be addressed both in a general and in a specific sense, whereby a number of yearbooks published all over the world will be looked at in further detail. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles in a varying thematic area of public international law.

This volume of the Netherlands Yearbook of International Law explores the many faces of populism, and the different manifestations of the relationship between populism and international law. Rather than taking the so-called populist backlash against globalisation, international law and governance at face value, this volume aims to dig deeper and wonders ‘What backlash are we talking about, really?’. While populism is contextual and contingent on the society in which it arises and its relationship with international law and institutions thus has differed likewise, this volume assists in our examination of what we find so dangerous about populism and problematic in its relationship with international law.

This book engages with international legal responses to the global environmental crisis. Humanity faces a triple planetary crisis, consisting of the interlinked problems of climate change, depletion of biological diversity and pollution.The chapters in this volume of the Netherlands Yearbook of International Law address important questions of how and to what extent these environmental concerns have been integrated into international law, who or what drives these developments, and what all of this tells us about international law’s ability to tackle the challenges that a deteriorating environment brings for the future of life on Earth. The strength of the volume is that it brings together a wide range of perspectives on the ‘greening’ phenomenon in international law. It includes perspectives from international environmental law, human rights law, investment law, financial law, humanitarian law and criminal law. Moreover, it raises important questions regarding the validity of the predominant approach in international law to (the protection of) nature. By providing such a wide range of perspectives on international legal responses (or lack thereof) to the environmental crisis, the volume seeks to engage scholars and practitioners from a variety of disciplines. It invites readers to compare the state-of-the-art across disciplines and to reflect on ways to strengthen international law’s responses to the environmental crisis. Furthermore, as has become standard for the Netherlands Yearbook of International Law, the second part consists of a section on Dutch practice in international law. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles in a varying thematic area of public international law.

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.

This Volume of the Netherlands Yearbook of International Law explores emerging trends and key developments in international economic law. It examines shifts in the levels of cooperation (from multilateral to plurilateral, regional or bilateral—or vice versa), and shifts in the forms of cooperation (new types of actors and instruments). These trends are analysed both from a conceptual and a practical perspective, with contributions addressing drivers for change, historical perspectives, future developments, and evolutions in specific policy fields. While a focus on international economic law may certainly not tell the whole story in relation to shifts in levels and forms of international cooperation, it does allow for a more detailed analysis of some of the important trends we currently witness. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles in a varying thematic area of public international law.

This volume of the Netherlands Yearbook of International Law (NYIL) addresses the question how the assumption that states have a common obligation to achieve a collective public good can be reconciled with the fact that the 195 states of today’s world are highly diverse and increasingly unequal in terms of size, population, politics, economy, culture, climate and historical development. The idea of common but differentiated responsibilities is on paper the perfect bridge between the factual inequality and formal equality of states. The acknowledgement that states can have common but still different – more or less onerous – obligations is predicated on the moral and legal concept of global solidarity. This book encompasses general contributions on the function and the content of the related principles, chapters that describe and evaluate how the principles work in a specific area of international law and chapters that address their efficiency and broader ramifications, in terms of compliance, free-rider behaviour and shifting balances of power. The originality of the book resides in the integration of conceptual, comparative and practical dimensions of the principles of global solidarity and common but differentiated responsibilities. The book is therefore highly recommended reading for both academics with a theoretical interest and those working within international organisations. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles in a varying thematic area of public international law.

This book provides a comprehensive account of the emergence of the customary law of human rights. It examines a range of human rights norms, and provides a useful guide to identifying those which can be described as customary.

In 2022, the ILC adopted the Draft Conclusions on Peremptory Norms of General International Law. The text of the Draft Conclusions consists of twenty-three Draft Conclusions and addresses two aspects: the identification of peremptory norms and their legal consequences. Attached to the Draft Conclusions is an Annex with a non-exhaustive list of jus cogens norms previously identified by the Commission. The International Law Commission's Draft Conclusions on Peremptory Norms serves, in part, as a commentary on the ILC's work and provides a broader understanding of the Draft Conclusions from the perspective of an insider. The book goes beyond a commentary, however, as it provides an analysis and evaluation of the broader legal issues raised by the Draft Conclusions. Relying inter alia on the discussions within the Commission and the doctrinal debate surrounding the concepts covered, the book will not only offer explanation of what is addressed in the Draft Conclusions but also an assessment of the choices made by the Commission and the consequences of those choices.

This book combines legal and philosophical perspectives to address the question of whether states are bound by human rights when they act with effects on people abroad—states’ extraterritorial human rights obligations. Taking an innovative approach, it begins with a profound legal analysis of the issue at national, supranational, and international levels and then engages in depth with counterarguments against extraterritorially applying human rights, on the basis of which it develops its own ethical justificatory theory of extraterritorial human rights obligations. The book closes the circle by showing what the practical implications of this theory for the interpretation (and possible evolvement) of human rights law would be. In a world where critiques of, and resistance to, the general idea of universal human rights are on rise, the book contributes to closing the gap between judicial and normative perspectives on extraterritorial human rights obligations by inquiring into the ethical underpinnings of this topical legal challenge. This book will be of key interest to scholars and students in human rights, international law, and more broadly in political philosophy, philosophy of law, and international relations.
