Making a connection between ‘post-modernism’ and post-truth has by now become a standard trope, both within academia and popular discourse, despite post-truth’s only recent emergence as a concept. Such claims are often rather vague and fanciful and lack an altogether credible account of either phenomenon in many cases. This Chapter argues however that within a legal context, there is the emergence of a legal post-truth which is the direct consequence of a concrete form of post-modernity within legal practice and thought. (...) While law may be called upon to engage in judgments of ‘truth’ in numerous interesting ways, it does not itself have any particular form of privileged access to the truth of statements or allegations, even though it is often treated as doing so. However, the most persistent question which law must deal with, and indeed the most persistent question within legal philosophy, relates to a deeper form of inquiry into truth: the question of legal truth. In simple terms this refers to the correctness of any particular proposition of law. Within legal theory, this expands to the larger question of what makes, in general, any legal proposition valid, or true. Reflecting upon legal scholarship through the lens of truth reveals that theories of law can be broken down into two broad and radically distinct categories. On the one hand, there exist empirical accounts of law which fundamentally understand questions of legal truth as social questions whose answers are empirically demonstrable. On the other hand, there are ‘idealist’ accounts of law which view legal content, and hence truth, as existing in some way or other in a manner which transcends social practice and which is autonomous from it. Both of these classical accounts, while radically different, share an interesting paradox: they see truth in law as an objective fact, but one which is fleeting and distant, far from the paradigm of legal certainty upon which the ideology of law is partly based. However, such accounts of legal truth share many other unstated aspects, and are largely based upon ideas which place the separateness and completeness of legal systems at their heart, providing either a unified ideal or a unified empirically observable social practice. However, they are share a common flaw, namely the failure to account for what might be called a post-modern phase of development in law, in which ordinary legal questions now regularly require the complex and non-hierarchical interaction of competing legal systems with different ‘truths’ and different ways of arriving at such truths. Such phenomena are commonly referred to as legal or, at times, constitutional ‘pluralism’. This post-modern turn within law has also produced therefore what we might call a form of post-truth within law. This is particularly significant because it places under great strain both the empirical and ideal accounts of legal truth and require us to re-elaborate an account of what makes a legal proposition true. From certain perspectives, this legal post-truth shares certain important aspects with the cultural phenomenon of post-truth, namely its apparently capricious and deracinated nature. However, it is argued in this Chapter that, in the legal context at least, post-truth allows for the transcendence of the empirical/ideal divide and the revealing of deeper forms of legal truth and our ability to account for them through theory or, put more simply, explanation. Upon greater reflection, legal truth is generated by the very forms of argument, or modes, which allow access to it. Such forms of argument exist also to produce legal truths outside and between legal orders where these appear to conflict or collide. While some legal scholars and others claim that such pressures on structures of knowledge reveal the end of the potential for law to generate truth, it is argued here that, on the contrary, they require a more open and more transparent use of the pure methods and modes of reason which both reveal but also generate legal truth in the first place. This is relevant to post-truth more generally in one specific way, despite the numerous idiosyncrasies of legal truth and knowledge: when assertions of truth within structures of power seem to come to embody the perspectivism and relativism used as methods of deconstruction, the post-modern and deconstructionist projects themselves require radical change: they stay true to their goal of deconstructing structures and discourses of power by applying the classical epistemologies which are rejected by those in power. Just as legal outcomes which are asserted rather than reasoned or justified are most convincingly deconstructed through sober legal modes, so can the post-modernist project find purpose in a world where dominant epistemes seem to have come to embody a simplistic version of post-modernist critiques.

In this book, I present the results of an investigation which began with an extended stay at Oxford's Balliol College during the first half of 1995. My visit to Oxford was made possible by a grant from the Spanish Ministerio de Educaci6n y Ciencia. My sincere thanks go to Joseph Raz who served as my supervisor in Oxford. For several points of the present study, conversations with Timothy Endicott in Oxford were also of great help. The book is part of (...) a larger project of investigation, directed by Albert Calsami glia, which is a joint effort of a group of legal philosophers from the Universitat Pom peu Fabra and the Universitat de Girona, and which also receives financial support from the Spanish Ministerio de Educaci6n y Ciencia. An earlier version of the manuscript was presented in June 1996 to the selection committee for a tenured professorship in Legal Philosophy at the Universitat de Girona. The members of the committee were Francisco Laporta, Albert Calsamiglia, Gregorio Peces-Barba, Camilo J. Cela Conde, and Francesca Puigpelat. I am grateful to all of them for their comments, which have been extremely useful in preparing the final ver sion of this book. (shrink)

The standard model of precedential constraint holds that a court is equally free to modify a precedent of its own and a precedent of a superior court—overruling aside, it does not differentiate horizontal and vertical precedents. This paper shows that no model can capture the U.S. doctrine of precedent without making that distinction. A precise model is then developed that does just that. This requires situating precedent cases in a formal representation of a hierarchical legal structure, and adjusting the constraint (...) that a precedent imposes based on the relationship of the precedent court and the instant court. The paper closes with suggestions for further improvements of the model. (shrink)

In this book, William Brant inquires how violence is reduced. Social causes of violence are exposed. War, sexual domination, leadership, propagandizing and comedy are investigated. Legal systems are explored as reducers and implementers of violence and threats.

In a paper published in 2006, I argued that the best way of defending something like our current practices of punishing war criminals would be to base the justification of this practice on an expressive theory of punishment. I considered two forms that such a justification could take—a ‘denunciatory’ account, on which the purpose of punishment is supposed to communicate a commitment to certain kinds of standard to individuals other than the criminal and a ‘communicative’ account, on which the purpose (...) of the punishment is to communicate with the perpetrator, and argued for a denunciatory account which I developed at some length. In this paper I would like to reconsider the plausibility of a communicative account. One difficulty that such accounts face is that the punishment of war criminals often involves the inflicting of harsh treatment on them by individuals who are members of states other than their own. On a communicative account this is problematic: on such an account—or at least on the version of it proposed by Duff (2000)—it is essential that those who are punish and those who punish them belong to a single community. When this requirement is not satisfied harsh treatment does not constitute punishment. Duff has argued that the problem can be solved by regarding all human beings as members of a single moral community: here I argue that this suggestion is unsatisfactory and propose an alternative. One consequence of my account is that if it is correct there may limitations on the range of kinds of war criminal that can legitimately be punished by international tribunals. (shrink)

Abstract.Although the Hart/Dworkin debate has as much to do with Dworkin's affirmative theory of judicial discretion as with Hart's more comprehensive theory of law, the starting point was of course Dworkin's attempt to demolish the “model of rules,” Hart's alleged analysis of legal systems as collections of conclusive reasons for specified legal consequences. The continuing relevance of this attack for the prospects for any theory of law is the subject of the present essay.

. This paper argues that legal philosophy is a social practice undertaken by participants whose views have primacy over non‐participants. This social practice is dynamic, constructive and based on understanding and explanation, in order to meet normative expectations. Legal Philosophy should include Legal Ontology, Legal Epistemology and a Theory of Justice. It is usually claimed that legal philosophy is a branch of a genus called philosophy, but there is no one single definition of it. In this paper it is argued (...) that as a starting point there is a need to choose between three basic traditions in philosophy. (shrink)

This paper sets out a view of a General Jurisprudence that is needed to underpin the institutionalised discipline of law as it becomes more cosmopolitan in the context of “globalisation”, and considers its implications. Part I restates a position on the mission and nature of the discipline of law and of the role of jurisprudence, as its theoretical part, in contributing to the health of the discipline. Part II clarifies some questions that have been raised about this conception of General (...) Jurisprudence: (i) the implications of “globalisation”; (ii) The meaning of “General Jurisprudence” in this context; (iii) The relationship between Jurisprudence, Legal Philosophy, and social scientific approaches to law; and (iv) The significance of the idea of “non-state law”. Part III illustrates through concrete examples some implications for possible agendas and issues suggested by this model within the areas roughly characterised as analytical, normative, empirical, and critical jurisprudence, including critical analysis of the assumptions and presuppositions typically underpinning mainstream work in fields such ascomparative law, public international law, religious law, and socio-legal studies.

Some legal theorists deny that states can conceivably act extra-legally, in the sense of acting contrary to domestic law. This position finds its most robust articulation in the writings of Hans Kelsen, and has more recently been taken up by David Dyzenhaus in the context of his work on emergencies and legality. This paper seeks to demystify their arguments and, ultimately, contend that we can intelligibly speak of the state as a legal wrongdoer or a legally unauthorized actor.

After proposing an alternative definition of what “law” (jurisprudential concept) is, this article demonstrates the impossibility of identifying “the law” (what law-makers announce, relative to a particular jurisdiction) as something that is in a particular way. Rather, the law is a more or less abstract range of options. Drawing upon this conclusion, the article calls for a reassessment of how we view the role of law-makers. We need to remove the mystery that surrounds the law so as to provide for (...) greater transparency. This transparency can be gained by requiring law-makers to declare their inescapable biases where they influence their lawmaking. (shrink)

In this article, I distinguish between a moral and a strictly legal conception of legal normativity, and argue that legal positivists can account for law's normativity in the strictly legal but not in the moral sense, while pointing out that normativity in the former sense is of little interest, at least to lawyers. I add, however, that while the moral conception of law's normativity is to be preferred to the strictly legal conception from the rather narrow viewpoint of the study (...) of law's normativity, it is less attractive than the latter from the broader viewpoint of the study of the nature of law. I then distinguish between a moral and a strictly legal conception of the normative force of legal justification, and argue that legal positivists may without contradiction embrace the moral conception, and that therefore the analysis of the normative force of legal justification need not be a problem for legal positivists. I conclude that, on the whole, we have reason to prefer legal positivism to natural law theory. I begin by introducing the subject of jurisprudence . I then introduce the natural law/legal positivism debate, suggesting that we ought to understand it as a debate about the proper way to explicate the concept of law . I proceed to argue that legal decision‐making is a matter of applying legal norms to facts, and that syllogistic reasoning plays a prominent role in legal decision‐making thus conceived . Having done that, I discuss law's normativity , the normative force of legal justification , and the relation between the former and the latter . I conclude with a critical comment on Joseph Raz’ understanding of the question of law's normativity. (shrink)

I argue in this article (i) that Karl Olivecrona's legal philosophy, especially the critique of the view that law has binding force, the analysis of the concept and function of a legal rule, and the idea that law is a matter of organized force, is a significant contribution to twentieth century legal philosophy. I also argue (ii) that Olivecrona fails to substantiate some of his most important empirical claims, and (iii) that the distinction espoused by Olivecrona between the truth and (...) the correctness of legal statements is problematic but not needed in Olivecrona's legal philosophy.

It will be argued, firstly, that there is a link between the legal validity of a norm and the rational justifiability of a requirement that judges should apply this norm, based on a normative conception of legal validity and the postulate that judges should act as rational persons; secondly, that rational justifiability of legal norms requires the construction of a legal system in a model of principles that differs from theories, e.g., of Kelsen, Hart, Dworkin and Alexy, which are not (...) fully adequate for a normative conception of law.

Anglo-American authors have paid little attention to a subtle distinction that has important jurisprudential implications. It is the distinction between sources of law and the legal norms which can be derived from sources by means of interpretation. The distinction might also be rendered as a threefold one, separating sources of law from legal norms and both of these from that which mediates their relation, namely, methods of legal interpretation. This paper intends to state the “source-norm” distinction clearly and to give (...) examples of jurisprudential insights that are missed, and mistakes that may be made if the distinction is not given its due.

In modern jurisprudence it is taken as axiomatic that John Austin's sanction-based account of law and legal obligation was demolished in H.L.A. Hart's The Concept of Law, but Hart's victory and the deficiencies of the Austinian account may not be so clear. Not only does the alleged linguistic distinction between being obliged and having an obligation fail to provide as much support for the idea of a sanction-independent legal obligation as is commonly thought, but the soundness of Hart's claims, as (...) well as the claims of many legal theorists who have followed him, depend on a contested view of the nature of legal theory. If the task of a theory of law, as Joseph Raz and others have influentially argued, is to identify the essential features of the concept of law, then the theoretical possibility, if not the empirical reality, of a sanction-free legal system is what is most important. But if the task of a theory of law is to provide philosophical and theoretical illumination of law as it exists and as it is experienced, then a theory of law that fails to give a central place to law's coercive reality may for that reason be deficient as a theory of law. The question of the soundness of the Austinian account, therefore, may be a function of the answer to the question of what a theory of law is designed to accomplish. (shrink)

The author analyzes fictions of legal positivist philosophy and their role in the scientific legitimation of modern law and political domination. The original function of legalist fictions was the establishment of legal science, which would be autonomous and independent of other social sciences and public morality. In the second half of the 20th century, legal positivist philosophy has nevertheless adopted the fiction of the just law as its scientific legitimation fiction and incorporated moral and political discourse into legal science, again.Legal (...) positivism and its critiques within the discourse of the sociology of law and critical legal science keep the image of a hierarchical and centralized legitimation of law. Paradoxically, current legal philosophy and theory searching for a universally valid legitimation scheme is full of many different legitimations and reveals their growing plurality and the impossibility of establishing one sovereign legitimation scheme in the current social, theoretical and political condition.

. A structured awareness of time lies at the core of the law's distinctive normativity. Melody is offered as a rough model of this mindfulness of time, since some important features of this awareness are also present in a hearer's grasp of melody. The model of melody is used, first, to identify some temporal dimensions of intentional action and then to highlight law's mindfulness of time. Its role in the structure of legal thinking, and especially in precedent‐sensitive legal reasoning, is (...) explored. This article argues further that melody‐modeled mindfulness of time is evident also at a deeper and more pervasive level, giving structure to the distinctive mode of law's normative guidance. The article draws one important theoretical consequence from this exploration, namely, that the normative coherence of momentary legal systems depends conceptually on their coherence over time.

The author analyzes the relations between truth and law starting from the distinction between practical and theoretical spheres. He shows, first, how moral and legal statements and reasoning are connected with an operation of weighing and balancing different values and principles and how this operation is ultimately based on personal and intuitive preferences and feeling. The criteria developed by the theoretical sciences to define truth (coherence, consensus and pragmatic success) can only be translated into practical statements as criteria of correctness (...) because we cannot affirm that a norm or value statement is true or false. The three criteria become interrelated indices of correctness: They are criteria for rational discourse. (shrink)

The separability thesis claims that the concept of law can be explicated independently of morality, the normativity thesis, that it can be explicated independently of fact. Continental normativism, prominent above all in the work of Hans Kelsen, may be characterized in terms of the coupling of these theses. Like Kelsen, H. L. A. Hart is a proponent of the separability thesis. And–a leitmotiv–both theorists reject reductive legal positivism. They do not, however, reject it for the same reasons. Kelsen's reason, in (...) a word, is the normativity thesis. Hart, however, grounds his theory in social fact. In place of the reductive thesis of the legal positivist tradition, and in sharp contrast to Kelsen's normativity thesis, Hart defends a non‐reductive version of what the author terms the facticity thesis.

Traditionally legal theorists, whenever engaged in controversy, have agreed on one point: legal norms are par excellence rules which impose obligations. The author examines this assumption, which from another perspective (that of constitutional law, for instance) appears less obvious. In fact, constitutional rules are commoniy empowering norms, norms which do not create duties but powers. To this objection many theorists would reply that empowering rules are incomplete and that they are to be understood as parts of duty‐creating rules. A different (...) position from this traditional stance is that defended in Kelsen's later writings, according to which the fundamental type of norm is the empowering norm. The author discusses Kelsen's three theories on the “ideal form” or structure of the legal norm, with special attention to the third of these, the empowerment theory. (shrink)

This paper is intended to be a summary of the author's views on the relationship between law and morality worked out over the past three decades in jurisprudence. The paper preliminarily clarifies the matter by isolating some lines of cleavage separating different questions askable about this relationship. With this done, the author argues for two theses. One, that judges are obligated to use morality in their decisions in particular cases; and two, that the morality judges are obligated to use in (...) their judicial reasonings, is best seen as the natural lawyer sees it, namely, as being part of the law that obligates judges in their role as judges. The author not only believes these theses to be true; he also thinks that these theses are practically important, in that their acceptance by judges makes for better judging. (shrink)

This article discusses C. E. Alchourrdn and E. Bulygin's ideas regarding the distinction between strong permission and weak permission. The author takes for granted that the distinction between the two terms should be placed at the level of the assertive metalanguage about norms. But the symbolizations and the definitions of strong and weak permissions offered by Alchourrdn and Bulygin, as well as their thesis concerning the relations between the two concepts are challenged.

This article summarizes the theory of federalism as non-domination Iris Marion Young began to develop in her final years, a theory of self-government that tried to recognize interconnectedness. Levy also poses an objection to that theory: non-domination cannot do the work Young needed of it, because it is a theory about the merits of decisions not about jurisdiction over them. The article concludes with an attempt to give Young the last word.

This paper presents an approach for legal compliance checking in the Semantic Web which can be effectively applied for applications in the Linked Open Data environment. It is based on modeling deontic norms in terms of ontology classes and ontology property restrictions. It is also shown how this approach can handle norm defeasibility. Such methodology is implemented by decidable fragments of OWL 2, while legal reasoning is carried out by available decidable reasoners. The approach is generalised by presenting patterns for (...) modeling deontic norms and norms compliance checking. (shrink)

A model of normative provisions and related axioms represented by using RDF/owl are presented as a contribution to implement the semantic web in the legal domain. In particular, a pattern able to implement the Hohfeldian legal fundamental relations between provisions using OWL-DL expressivity is proposed. Moreover, a query-based approach able to deal with relations between provision instances is described. An example of advanced access and reasoning over provisions using the proposed approach, as well as a prototype architecture of a provision (...) retrieval system, are shown. The main benefit is represented by the ability of the approach to keep the complexity of the problem within a description logic computational tractability. (shrink)

El positivismo jurídico como teoría sobre la existencia del derecho: un comentario sobre Judging Positivism de Margaret Martin Este comentario examina de forma crítica la concepción de positivismo jurídico que informa el desafío planteado por Margaret Martin contra la substancia y el método de esta tradición intelectual. La afirmación central de este artículo es que su caracterización de la teoría substantiva del positivismo jurídico deja de lado una dimensión más fundamental, y explicativamente previa, relacionada a la teoría positivista de la (...) existencia de los sistemas y normas jurídicas. También sostengo que su caracterización de la metodología descriptiva del positivismo como un proyecto no normativo es demasiado exigente y no puede capturar la relaciones entre derecho y moral reconocidas por los positivistas contemporáneos ni la distinción entre preguntas internas y externas. Estas clarificaciones proporcionan recursos para comenzar a responder algunas de las objeciones de Martín contra el proyecto de Raz. (shrink)

Assuming that legal science, specifically with regard to interpretation, has to provide the tools to reduce the uncertainty of legal solutions arising from the use of natural languages by legal orders, it becomes a central matter to identify, in this limited domain, the spectrum of semantic variation (and its boundaries) that language brings to the definition of a norm expressed by a norm sentence. It is in this framework that the present paper, analyzing norm sentences as a specific kind of (...) speech act, examines the relation of the legal order to natural language rules, the limits of linguistic uncertainty, and alternatives of meaning as distinct possibilities of norms covered by the text (that are, because of this, still within what literal meaning is). Considering interpretation just as the linguistic decoding process, the reverse of the process of creating norm sentences, the paper also argues that subjects not connected with the relation between norm sentences and norms (mainly, normative defeasibility) are analytically distinct and should be removed from the field of language.

Hart's and Kelsen's respective outlooks on the concept of normativity not only differ by the way they explain this concept but also, more importantly, in what they seek to achieve when endeavouring to account for the normative dimension of law. By examining Hart's and Kelsen's models in the light of Korsgaard's understanding of the “normativity problem,” my aim is to emphasise not only their contrasted perspectives, but also the common limit they impose on their theories by dismissing as inappropriate any (...) question regarding the emergence of legal normativity. On the basis of my previous arguments, I shall explain why I deem Raz's analysis of the contrast between Hart's and Kelsen's conceptions of normativity to be misleading. (shrink)

ABSTRACT In recent years, debates on same-sex marriage and the recognition of transwomen as women have been raging. These debates often seem to revolve around the meaning of, respectively, the word ‘marriage’ and ‘woman’. That such debates should take place might be puzzling. It seems that if debates on gay and transgender rights revolve around the meaning of these words, then those in favor of same-sex marriage and of the recognition of transwomen as women have no room left to maneuver. (...) However, prima facie, the pro – and anti-, in both cases, have genuine disagreements over the meaning of these words: though the analyses of revisionary theorists are revisionary, they are analyses. Sally Haslanger and other philosophers in her wake have appealed to an anti-descriptivist externalist view of meaning to provide the conceptual foundations of this practice of revisionary theorizing: revisionary analyses bring to light what, unbeknownst to us, these words mean. In this paper, I argue that a descriptivist externalist view should be preferred instead. My argument rests on the thesis that what is contested in these debates is the meaning of the words ‘marriage’ and ‘women’ as used in the law. (shrink)

Carlos Eduardo Alchourrón y Eugenio Bulygin efectuaron contribuciones de fundamental importancia para el desarrollo de la teoría de los sistemas jurídicos. Sus ideas evidencian una evolución de la presentación de una visión estática a una visión dinámica de tales sistemas. El objetivo central del presente trabajo consiste en mostrar que existe, no obstante, una cierta tensión en las tesis sostenidas por los autores entre dos concepciones diferentes de los sistemas jurídicos: por una parte, aquella que trata de reconstruir el conjunto (...) de las normas que resultan relevantes para la solución de un caso; por la otra, aquella que trata de ofrecer una caracterización satisfactoria del derecho como institución. Las diferentes finalidades que cada una de esas reconstrucciones persiguen obligan a refinar algunas ideas vinculadas con la dinámica del derecho para evitar derivaciones incompatibles con las intuiciones jurídicas ordinarias. Carlos Eduardo Alchourrón and Eugenio Bulygin have made contributions of fundamental importance for the development of the theory of legal systems. Their ideas reflex an evolution from a static to a dynamic vision of such systems. The main purpose of the present paper is to show that, notwithstanding, there exists a certain tension in the thesis defended by Alchourrón and Bulygin between two different conceptions of a legal system. On the one hand, a conception related to the reconstruction of the set of relevant norms to solve a certain case; on the other, a conception related to a satisfactory characterization of law as an institution. The different concerns of each of those reconstructions force to refine certain ideas associated with the dynamics of law to avoid derivations which appear incompatible with ordinary legal intuitions.

This paper aims to explore two objections raised against Bulygin’s second approach to the definition of the nature of legal power-conferring rules. According to the first objection, such an account is vague about what is defined by legal power-conferring rules qua constitutive rules. I maintain that this vagueness is rooted in the lack of a suitable definition of legal power. I shall be arguing for the reduction of the complexity of the definientia by defining legal power as a species of (...) competence. According to the second objection, this non-reductive approach cannot explain the normativity of this kind of rules. Against this approach, it argues that legal powerconferring rules perform a deontic and a definitional function as constitutive rules of legal practice. (shrink)
