Présentation de l'éditeur: "This work offers a new theory of what it means to be a legal person and suggests that it is best understood as a cluster property. The book explores the origins of legal personhood, the issues afflicting a traditional understanding of the concept, and the numerous debates surrounding the topic."

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.

This Element presents the notion of legal personhood, which is a foundational concept of Western law. It explores the theoretical and philosophical foundations of legal personhood, such as how legal personhood is defined and whether legal personhood is connected to personhood as a general notion. It also scrutinises particular categories of legal personhood. It first focuses on two classical categories: natural persons (human beings) and artificial persons (corporations). The discussions of natural persons also cover the developing legal status of children and individuals with disabilities. The Element also presents three emerging categories of legal personhood: animals, nature and natural objects, and AI systems. This title is also available as Open Access on Cambridge Core.

This book explores the legal conception of personhood in the context of contemporary challenges, such as the status of non-human animals, human-animal biological mixtures, cyborgisation of the human body, or developing technologies based on artificial autonomic agents. It reveals the humanistic assumptions underlying the legal approach to personhood and examines the extent to which they are undermined by current and imminent scientific and technological advances. Further, the book outlines an original conception of non-personal subjecthood so as to provide adequate normative solutions for the problematic status of sentient animals and other kinds of entities. Arguably, non-personal subjects of law should be regarded as holding one right, and only one right - the right to be taken into account.

This volume showcases emerging interdisciplinary scholarship that captures the complex ways in which biological knowledge is testing the nature and structure of legal personhood. Key questions include: What do the new biosciences do to our social, cultural, and legal conceptions of personhood? How does our legal apparatus incorporate new legitimations from the emerging biosciences into its knowledge system? And what kind of ethical, socio-political, and scientific consequences are attached to the establishment of such new legalities? The book examines these problems by looking at materialities, the posthuman, and the relational in the (un)making of legalities. Themes and topics include postgenomic research, gene editing, neuroscience, epigenetics, precision medicine, regenerative medicine, reproductive technologies, border technologies, and theoretical debates in legal theory on the relationship between persons, property, and rights.

The concept of convention has been used in different fields and from different perspectives to account for important social phenomena, and the legal sphere is no exception. Rather, reflection on whether the legal phenomenon is based on a convention and, if so, what kind of convention is involved, has become a recurring issue in contemporary legal theory. In this book, some of the foremost specialists in the field make significant contributions to this debate. In the first part, the concept of convention is analysed. The second part reflects on whether the rule of recognition postulated by Hart can be understood as a convention and discusses its potential and limitations in order to explain the institutional and normative character of law. Lastly, the third part critically examines the relations between conventionalism and legal interpretation. Given the content and quality of the contributions, the book is of interest to those wanting to understand the current state of the art in legal conventionalism as well as those wanting to deepen their knowledge about these questions.

The perennial question posed by the philosophically-inclined lawyer is 'What is law?' or perhaps 'What is the nature of law?' This book poses an associated, but no less fundamental, question about law which has received much less attention in the legal literature. It is: 'Who is law for?' Whenever people go to law, they are judged for their suitability as legal persons. They are given or refused rights and duties on the basis of ideas about who matters. These ideas are basic to legal-decision making; they form the intellectual and moral underpinning of legal thought. They help to determine whether law is essentially for rational human beings or whether it also speaks to and for human infants, adults with impaired reasoning, the comotose, foetuses and even animals. Are these the right kind of beings to enter legal relationships and so become legal persons. Are they, for example, sufficiently rational, or sacred or simply human? Is law meant for them? This book reveals and evaluates the type of thinking that goes into these fundamental legal and metaphysical determinations about who should be capable of bearing legal rights and duties. It identifies and analyses four influential ways of thinking about law's person, each with its own metaphysical suppositions. One approach derives from rationalist philosophy, a second from religion, a third from evolutionary biology while the fourth is strictly legalistic and so endeavours to eschew metaphysics altogether. The book offers a clear, coherent and critical account of these complex moral and intellectual processes entailed in the making of legal persons.
