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 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.

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 (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 1999 Netherlands Yearbook of International Law contains expert articles on issues such as `Re-inventing the law of treaties: the contribution of the EC Courts'; `Levies on aircraft engine fuel--the international legal framework'; `Decisions of international organizations: the case of the European Union'. The documentation section surveys Dutch state practice for the parliamentary year 1997-1998; international agreements to which the Netherlands is a party; Netherlands judicial decisions and municipal legislation involving questions of public international law, and Dutch literature in the field of public international law and related matters. This Yearbook is included in the 1999 subscription to the Netherlands International Law Review (Volume 46).

The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles of a more general nature in the area of public international law including the law of the european Union. One of the key functions or purposes of international law (and law in general for that matter) is to provide long-term stability and legal certainty. Yet, international legal rules may also function as tools to deal with non-permanent or constantly changing issues and rather than stable, international law may have to be flexible or adaptive. Prima facie, one could think of two main types of temporary aspects relevant from the perspective of international law. First, the nature of the object addressed by international law or the ‘problem’ that international law aims to address may be inherently temporary (temporary objects). Second, a subject of international law may be created for a specific period of time, after the elapse of which this entity ceases to exist (temporary subjects). These types of temporariness raise several questions from the perspective of international law, which are hardly addressed from a more conceptual perspective. This volume of the Netherlands Yearbook of International Law aims to do exactly that by asking the question of how international law reacts to various types of temporary issues. Put differently, where does international law stand on the continuum of predictability and pragmatism when it comes to temporary issues or institutions?
