Several international legal issues are related to the concept of legal personality, including the determination of international rights and duties of non-state actors and the legal capacities of transnational institutions. When addressing these issues, different understandings of legal personality are employed. These concepts consider different entities to be international persons, state different criteria for becoming one and attach different consequences to being one. In this book, Roland Portmann systematizes the different positions on international personality by spelling out the assumptions on which they rest and examining how they were substantiated in legal practice. He puts forward the argument that positions on international personality which strongly emphasize the role of states or effective actors rely on assumptions that have been discarded in present international law. The principal argument is that international law has to be conceived as an open system, wherein there is no presumption for or against certain entities enjoying international personality.

"Legal personality is a concept present in international law. It is principally employed to distinguish between those social entities relevant to the international legal system and those excluded from it. There is almost universal agreement that states are international persons"--

This is the first monograph to scrutinize the relationship between the concept of international legal personality as a theoretical construct and the position of the ultimate subject, the individual, as a matter of positive international law. By testing the four main theoretical conceptions of international legal personality against historical and existing norms of positive international law that regulate the conduct of individuals, the book argues that the common narrative in contemporary scholarship about the development of the role of the individual in the international legal system is flawed. Contrary to conventional wisdom, international law did not apply to states alone until World War II, only to transform during the second half of the 20th century so as to include individuals as its subjects. Rather, the answer to the question of individual rights and obligations under international law is - and always was - strictly empirical. It follows, of course, that the entities governed by a particular norm tell us nothing about the legal system to which that norm belongs. Instead, the distinction between international law and national law turns exclusively on whether the source of the norm in question is international or national in kind. Against the background of these insights, the book shows how present-day international lawyers continue to allow an idea, which was never more than a scholarly invention of the 19th century, to influence the interpretation and application of international law. This state of affairs has significant real-world ramifications as international legal rights and obligations of individuals (and other non-state entities) are frequently applied more restrictively than interpretation without presumptions regarding 'personality' would merit.

Beyond Human Rights, previously published in German and now available in English, is a historical and doctrinal study about the legal status of individuals in international law.

This book is the report of a journey. The reader is invited to join the author on a th trip in time and space. The trip takes its starting-point in 17 century Europe and th the as yet confused post-Thirty Years War society. After some stops in the 18 th and 19 century the author brings us to the post-World War I society which is as confused and is torn between ideals and despair. Then we make a stop in the post-World War II society when ideals seemingly have made place for trust in power but where we also get a glance of the fragile sapling of human rights law. And finally we pause in the post-Cold War world and try to cast a look into the future. What is the purpose of this journey, what is the author in search of? As is clear from the title it is the concept of International Legal Personality which for many will have a rather formal and positive law connotation. But the journey does not take us into the cabinets of Foreign Ministries or to conference-rooms or United Nations-buildings where the law is made nor to the court-rooms where the law is interpreted and modelled.
