This illuminating book explores the theme of social constructionism in legal theory. It questions just how much freedom and power social groups really have to construct and reconstruct law. Michael Giudice takes a nuanced approach to analyse what is true and what is false in the view that law is socially constructed. He draws on accounts of European Union law as well as Indigenous legal orders in North America to demonstrate the contingency of particular concepts of law. Utilising evidence from a range of social and natural sciences, he also considers how law may have a naturally necessary core. The book concludes that while law would not exist without beliefs, intentions, and practices, it must always exist as a social rule, declaration, or directive; much, but not all, of law is socially constructed. This book will be a valuable resource for academics and students of law and philosophy as well as researchers interested in the intersections between analytical legal theory, socio-legal studies, and empirical legal studies.

Understanding the Nature of Law explores methodological questions about how best to explain law. Among these questions, one is central: is there something about law which determines how it should be theorized? Michael Giudice presents the problem: several methods suggest themselves as suitable to understanding law; however, each method claims unique importance with no need of others. A solution is offered in two key claims. First, many conceptual theories of law are best understood not as the result of conceptual analysis, but as constructive conceptual explanations, emphasizing a crucial role for revision and expansion of ordinary concepts, in ways responsive to new problems and new phenomena. Second, conceptual theories of law can and ought to identify necessary as well as contingent features in the construction of conceptual explanations of law. This novel book explains the importance of conceptual explanation by situating its methods and goals in relation to, rather than in competition with, social scientific and moral theories of law. The book will be of primary interest to both students and academics in legal, political, and moral philosophy. It will also be of interest to students and academics working in the social sciences who are interested in questions about the distinctive character of law.

Analytical jurisprudence often proceeds with two key assumptions: that all law is either contained in or traceable back to an authorizing law-state, and that states are stable and in full control of the borders of their legal systems. What would a general theory of law be like and do if these long-standing presumptions were loosened? The Unsteady State aims to assess the possibilities by enacting a relational approach to explanation of law, exploring law's relations to the environment, security, and technology. The account provided here offers a rich and renewed perspective on the preconditions and continuity of legal order in systemic and non-systemic forms, and further supports the view that the state remains prominent yet is now less dominant in the normative lives of norm-subjects and as an object of legal theory.

English-speaking jurisprudence of the last 100 years has devoted considerable attention to questions of identity and continuity. H.L.A. Hart, Joseph Raz, and many others have sought means to identify and distinguish legal from non-legal social situations, and to explain the enduring legality of those typically dynamic social situations. Focus on characterization of legality associated with the state, the most prominent legal phenomena available, has led to an analytical approach dominated by the idea of legal system and analysis of its constituent norms. Yet as far back as Hart's 1961 encounter with international law, the system-focussed approach to legality has experienced moments of self-doubt. From international law to the new legal order of the European Union, to shared governance and overlapping jurisdiction in transboundary areas, what at least appear to be instances of legality are at best weakly explained by approaches which presume the centrality of legal system as the mark and measure of social situations fully worthy of the title of legality. What next, as phenomena threaten to outstrip theory? Legality's Borders: An Essay in General Jurisprudence explains the rudiments of an inter-institutional theory of law, a theory which finds legality in the interaction between legal institutions, whose legality we characterise in terms of the kinds of norms they use rather than their content or system-membership. Prominent forms of legality such as the law-state and international law are then explained as particular forms of complex agglomeration of legal institutions, varying in form and complexity rather than sheer legality. This approach enables a fundamental shift in approach to the problems of identity and continuity of characteristically legal situations in social life: once legality is decoupled from legal system, the patterns of intense mutual reference amongst the legal institutions of the law-state can be seen as one justifiably prominent form of legality amongst others including overlapping forms of legality such as the European Union. Identity over time, on this view, is less a fixed set of characteristics than a history of intense mutual interaction of legal institutions, comparable against similar other agglomerations of legal institutions.

The last decade has witnessed a particularly intensive debate over methodological issues in legal theory. The publication of Julie Dickson's Evaluation and Legal Theory (2001) was significant, as were collective returns to H.L.A. Hart's 'Postscript' to The Concept of Law. While influential articles have been written in disparate journals, no single collection of the most important papers exists. This volume - the first in a three volume series - aims not only to fill that gap but also propose a systematic agenda for future work. The editors have selected articles written by leading legal theorists, including, among others, Leslie Green, Brian Leiter, Joseph Raz, Ronald Dworkin, and William Twining, and organized under four broad categories: 1) problems and purposes of legal theory; 2) the role of epistemology and semantics in theorising about the nature of law; 3) the relation between morality and legal theory; and 4) the scope of phenomena a general jurisprudence ought to address.
