When a legal rule requires us to drive on the right, notarize our wills, or refrain from selling bootleg liquor, how are we to describe and understand that requirement? In particular, how does the logical form of such a requirement relate to the logical form of other requirements, such as moral requirements, or the requirements of logic itself? When a general legal rule is applied or distinguished in a particular case, how can we describe that process in logical form? Such questions have come to preoccupy modern legal philosophy as its methodology, drawing on the philosophy of logic, becomes ever more sophisticated. This collection gathers together some of the most prominent legal philosophers in the Anglo-American and civil law traditions to analyse the logical structure of legal norms. They focus on the issue of defeasibility, which has become a central concern for both logicians and legal philosophers in recent years. The book is divided into four parts. The first section is devoted to unravelling the basic concepts related to legal defeasibility and the logical structure of legal norms, focusing on the idea that law, or its components, are liable to implicit exceptions, which cannot be specified before the law's application to particular cases. Part two aims to disentangle the main relations between the issue of legal defeasibility and the issue of legal interpretation, exploring the topic of defeasibility as a product of certain argumentative techniques in the law. Section 3 of the volume is dedicated to one of the most problematic issues in the history of jurisprudence: the connections between law and morality. Finally, section 4 of the volume is devoted to analysing the relationships between defeasibility and legal adjudication.

Does the law contain implicit exceptions to its own rules? If so, what consequence does that have for understanding the relationship between law and morality? This collection gathers leading legal philosophers to analyse the logical structure of legal norms, advancing the understanding of the general philosophy of law.

This book focuses on the problems of rules, rule-following and normativity as discussed within the areas of analytic philosophy, linguistics, logic and legal theory. Divided into four parts, the volume covers topics in general analytic philosophy, analytic legal theory, legal interpretation and argumentation, logic as well as AI& Law area of research. It discusses, inter alia, “Kripkenstein’s” sceptical argument against rule-following and normativity of meaning, the role of neuroscience in explaining the phenomenon of normativity, conventionalism in philosophy of law, normativity of rules of interpretation, some formal approaches towards rules and normativity as well as the problem of defeasibility of rules. The aim of the book is to provide an interdisciplinary approach to an inquiry into the questions concerning rules, rule-following and normativity.

This handbook addresses legal reasoning and argumentation from a logical, philosophical and legal perspective. The main forms of legal reasoning and argumentation are covered in an exhaustive and critical fashion, and are analysed in connection with more general types (and problems) of reasoning. Accordingly, the subject matter of the handbook divides in three parts. The first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the general structures and procedures of reasoning and argumentation that are relevant to legal discourse. The third one looks at their instantiations and developments of these aspects of argumentation as they are put to work in the law, in different areas and applications of legal reasoning.

This book presents the current state of the art regarding the application of logical tools to the problems of theory and practice of lawmaking. It shows how contemporary logic may be useful in the analysis of legislation, legislative drafting and legal reasoning concerning different contexts of law making. Elaborations of the process of law making have variously emphasised its political, social or economic aspects. Yet despite strong interest in logical analyses of law, questions remains about the role of logical tools in law making. This volume attempts to bridge that gap, or at least to narrow it, drawing together some important research problems—and some possible solutions—as seen through the work of leading contemporary academics. The volume encompasses 20 chapters written by authors from 16 countries and it presents diversified views on the understanding of logic (from strict mathematical approaches to the informal, argumentative ones) and differentiated choices concerning the aspects of law making taken into account. The book presents a broad set of perspectives, insights and results into the emerging field of research devoted to the logical analysis of the area of creation of law. How does logic inform lawmaking? Are legal systems consistent and complete? How can legal rules be represented by means of formal calculi and visualization techniques? Does the structure of statutes or of legal systems resemble the structure of deductive systems? What are the logical relations between the basic concepts of jurisprudence that constitute the system of law? How are theories of legal interpretation relevant to the process of legislation? How might the statutory text be analysed by means of contemporary computer programs? These and other questions, ranging from the theoretical to the immediately practical, are addressed in this definitive collection.

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.

Autonomy is the central idea of modern practical philosophy. Understood as self-legislation, autonomy seems to require that the validity of norms depends on recognition, namely, that their addressees, being autonomous agents, recognise these norms to be valid. But how can one be bound by norms whose validity depends on their being recognised as valid by their addressees? The questions of how autonomous morality and, on this basis, the authoritative character of law can be understood, present persistent puzzles that have been widely discussed, but still await a satisfactory solution. This book presents an analysis of the idea of autonomy as self-legislation and its consequences for law and morality. It links the idea of autonomy with the idea of the balancing of normative arguments, develops a notion of normative arguments as distinct from normative judgements and statements and explains claims to correctness and objectivity that are found in normative discourse. Thus, a 'logic of autonomy' emerges, and it is pervasive in normative reasoning. It connects theses regarding the logic of norms, the structure of balancing, human and fundamental rights, legal validity, legal interpretation, and the relations among legal systems, offering a theory of central elements of normative argumentation, a theory that is undergirded by the mutual relations that exist between and among its parts as well as through the relations that it bears to other theories. Moreover, it offers an alternative to Kantian notions of autonomy and provides solutions to problems that other theories have failed to master.

The Blackwell Companion to Law and Society is an authoritative study of the relationship between law and social interaction. Thirty-two original essays by an international group of expert scholars examine a wide range of critical questions. Authors represent various theoretical, methodological, and political commitments, creating the first truly global overview of the field. Examines the relationship between law and social interactions in thirty-three original essay by international experts in the field. Reflects the world-wide significance of North American law and society scholarship. Addresses classical areas and new themes in law and society research, including: the gap between law on the books and law in action; the complexity of institutional processes; the significance of new media; and the intersections of law and identity. Engages the exciting work now being done in England, Europe, Australia, and New Zealand, South Africa, Israel, as well as "Third World" scholarship.

In the same way that it has become part of all our lives, computer technology is now integral to the work of the legal profession. The JURIX Foundation has been organizing annual international conferences in the area of computer science and law since 1988, and continues to support cutting-edge research and applications at the interface between law and computer technology. This book contains the 16 full papers and 6 short papers presented at the 26th International Conference on Legal Knowledge and Information Systems (JURIX 2013), held in December 2013 in Bologna, Italy. The papers cover a wide range of research topics and application areas concerning the advanced management of legal information and knowledge, including computational techniques for: classifying and extracting information from, and detecting conflicts in, regulatory texts; modeling legal argumentation and representing case narratives; improving the retrieval of legal information and extracting information from legal case texts; conducting e-discovery; and, applications involving intellectual property and IP licensing, online dispute resolution, delivering legal aid to the public and organizing the administration of local law and regulations. The book will be of interest to all those associated with the legal profession whose work involves the use of computer technology.

Many international obligations are subject to exceptions. These can be expressed in several ways: an obligation may be vitiated by the presence of one of its constitutive negative requirements, an obligation may be set aside by the application of another more specific rule, or an actor might have a right to act in a certain way notwithstanding a contrary obligation. Exceptions are also of fundamental practical importance: for example, they affect the allocation of the burden of proof. This volume provides a systematic and analytic study of exceptions to legal obligations in international law and defences for breaches of these obligations. It features contributions written by legal philosophers, who introduce various theoretical approaches to the role of exceptions, and scholars of international law, who elaborate on generic issues applicable to exceptions in international law as well as examine specific issues arising from exceptions in their respective areas of expertise. Topics covered include the use of force, international criminal law, human rights, trade, investment, environment, and jurisdictional immunities.
