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.

The European Yearbook of Constitutional Law (EYCL) is an annual publication devoted to the study of constitutional law. It aims to provide a forum for in-depth analysis and discussion of new developments in the field, both in Europe and beyond. This third volume of the EYCL focuses on constitutional advice, an underexplored topic of legal scholarship today, and addresses this situation by looking beyond constitutional law’s familiar focus on the classic separation of powers and the main legislative, executive and judicial bodies implied by this construct. The attention is shifted to mapping and analysing the advisory bodies and functions grouped around and in support of the legislators, administrators and judges at the frontline of the constitutional edifice, which is accomplished through national, comparative and transnational perspectives on constitutional advice from Europe and beyond. Addressing the topic of constitutional advice is necessary to broaden and deepen not only our understanding of advice as a field in its own right, but also as a way of rendering a fuller account of contemporary constitutionalism. Also, the increasing political polarisation across many societies today underscores the need to study constitutional advice on topics of significance in an attempt to bridge divides and end gridlock. This book will be of special interest to constitutional scholars and legal scholars more generally, as well as to political scientists. In addition, government officials, judges and policy-makers wishing to better understand the legal mechanisms and avenues when it comes to rendering or receiving advice in the contemporary constitutional context will find much of relevance.

This is the first edition of the Yearbook on the African Union. It is first and foremost an academic project that will provide an in-depth evaluation and analysis of the institution, its processes, and its engagements. Despite the increased agency in recent years of the African Union in general, and the AU Commission in particular, little is known – outside expert policy or niche academic circles – about the Union’s activities. This is the gap the Yearbook on the African Union wants to systematically bridge. It seeks to be a reference point for in-depth research, evidence-based policy-making and decision-making. Contributors are: Adekeye Adebajo, Habibu Yaya Bappah, Bruce Byiers, Annie Barbara Hazviyemurwi Chikwanha, Dawit Yohannes Wondemagegnehu, Katharina P.W. Döring, Jens Herpolsheimer, Jacob Lisakafu, Frank Mattheis, Henning Melber, Alphonse Muleefu, John N. Nkengasong, Edefe Ojomo, Awino Okech, Jamie Pring, Elizabeth Sidiropoulos, Tim Zajontz.

Launched in 1991, the Asian Yearbook of International Law is a major internationally-refereed yearbook dedicated to international legal issues as seen primarily from an Asian perspective. It is published under the auspices of the Foundation for the Development of International Law in Asia (DILA) in collaboration with DILA-Korea, the Secretariat of DILA, in South Korea. When it was launched, the Yearbook was the first publication of its kind, edited by a team of leading international law scholars from across Asia. It provides a forum for the publication of articles in the field of international law and other Asian international legal topics. The objectives of the Yearbook are two-fold: First, to promote research, study and writing in the field of international law in Asia; and second, to provide an intellectual platform for the discussion and dissemination of Asian views and practices on contemporary international legal issues. Each volume of the Yearbook contains articles and shorter notes; a section on Asian state practice; an overview of the Asian states’ participation in multilateral treaties and succinct analysis of recent international legal developments in Asia; a bibliography that provides information on books, articles, notes, and other materials dealing with international law in Asia; as well as book reviews. This publication is important for anyone working on international law and in Asian studies. The 2018 edition of the Yearbook features articles on the practice of Asian states from the perspective of Third World Approaches to International Law (TWAIL).
