In this reprint of Law's Empire,Ronald Dworkin reflects on the nature of the law, its given authority, its application in democracy, the prominent role of interpretation in judgement, and the relations of lawmakers and lawgivers to the community on whose behalf they pronounce. For that community, Law's Empire provides a judicious and coherent introduction to the place of law in our lives.Previously Published by Harper Collins. Reprinted (1998) by Hart Publishing.

This work represents Niklas Luhmann's definitive application of systems theory to the understanding of law. In it Luhmann reviews past attempts to create a theory of law and argues they all fail to capture how law operates in modern society. He presents an alternative, critical theory through analysing law as a system of communication.

Hans Kelsen is considered by many to be the foremost legal thinker of the twentieth century. During the last decade of his life he was working on what he called a general theory of norms. Published posthumously in 1979 as Allgemeine Theorie der Normen, the book is here translated for the first time into English. Kelsen develops his "pure theory of law" into a "general theory of norms", and analyzes the applicability of logic to norms to offer an original and (...) extreme position which some have called "normative irrationalism". Examining the views of over 200 philosophers and legal theorists on law, morality, and logic, and revising several of his own earlier positions, Kelsen's final work is a mandatory resource for legal and moral philosophers.

In this volume, Niklas Luhmann, the leading exponent of systems theory, explores its implications for our understanding of law. The volume provides a rigorous application to law of a theory that offers profound insights into the relationships between law and other aspects of contemporary society, including politics, the economy, the media, education, and religion.Readership: Academics and students of sociology, law, philosophy, and legal philosophy.

In this paper we investigate how to represent and reason about legal abrogations and annulments in Defeasible Logic. We examine some options that embed in this setting, and in similar rule-based systems, ideas from belief and base revision. In both cases, our conclusion is negative, which suggests to adopt a different logical model. This model expresses temporal aspects of legal rules, and distinguishes between two main timelines, one internal to a given temporal version of the legal system, and another relative (...) to how the legal system evolves over time. Accordingly, we propose a temporal extension of Defeasible Logic suitable to express this model and to capture abrogation and annulment. We show that the proposed framework overcomes the difficulties discussed in regard to belief and base revision, and is sufficiently flexible to represent many of the subtleties characterizing legal abrogations and annulments.

The Province of Jurisprudence Determined (1832) is a classic of nineteenth-century English jurisprudence, a subject on which Austin had a profound impact. His book is primarily concerned with a meticulous explanation of most of the core concepts of his legal philosophy, including his conception of law, his separation of law and morality, and his theory of sovereignty. Almost a quarter of it consists of an interpretation and defence of the principle of utility. This edition includes the complete and unabridged text (...) of the fifth (1885) and last edition. The comprehensive introduction discusses Austin's life, the main themes of his book, leading criticisms of his ideas, and recent interpretations of his legal philosophy. The edition also includes an up-to-date bibliography and biographical synopses of the principal figures mentioned in the text. (shrink)

This paper provides a computational framework, based on defeasible logic, to capture some aspects of institutional agency. Our background is Kanger-Lindahl-Pörn account of organised interaction, which describes this interaction within a multi-modal logical setting. This work focuses in particular on the notions of counts-as link and on those of attempt and of personal and direct action to realise states of affairs. We show how standard defeasible logic (DL) can be extended to represent these concepts: the resulting system preserves some basic (...) properties commonly attributed to them. In addition, the framework enjoys nice computational properties, as it turns out that the extension of any theory can be computed in time linear to the size of the theory itself. (shrink)

Reasoning about causation in fact is an essential element of attributing legal responsibility. Therefore, the automation of the attribution of legal responsibility requires a modelling effort aimed at the following: a thorough understanding of the relation between the legal concepts of responsibility and of causation in fact; a thorough understanding of the relation between causation in fact and the common sense concept of causation; and, finally, the specification of an ontology of the concepts that are minimally required for (automatic) common (...) sense reasoning about causation. This article offers a worked-out example of the indicated analysis. Such example consists of: a definition of the legal concept of responsibility (in terms of liability and accountability); a definition of the legal concept of causation in fact (in terms of the initiation of physical processes by an agent and of the provision of reasons and/or opportunities to other agents); CausatiOnt, an AI-like ontology of the common sense (causal) concepts that are minimally needed for reasoning about the legal concept of causation in fact (in particular, the concepts of category, dimension, object, agent, process, event and act).
