Hume’s Law that one cannot derive an “ought” from an “is” has often been deemed to bear a significance that extends far beyond logic. Repeatedly, it has been invoked as posing a serious threat to views about normativity: naturalism in metaethics and positivism in jurisprudence. Yet in recent years, a puzzling asymmetry has emerged: while the view that Hume’s Law threatens naturalism has largely been abandoned (due mostly to Pigden’s work, see e.g. Pigden 1989), the thought that Hume’s Law is (...) a serious challenge to positivism has only grown in prominence. Our main aim is to establish that Hume’s Law is not a threat to positivism or naturalism. First, we connect extensive, but unfortunately siloed, discussions of this issue. Second, we show that Hume’s Law is not a serious threat to naturalism or positivism, for the gap between logic and such theses is very hard to bridge in a way that would make Hume’s Law able to bear this significance. Finally, we emphasize an implication of our discussion: it undermines one of the main “dialectical tributaries” in jurisprudence (Toh 2018). (shrink)

A diverse range of actors, from practitioners and academics to civil society groups and activists, appear to see hope in international law for the advancement of their causes. This article examines whether this optimism is well-founded. It explores whether international law can serve as an agent of social change, and whether it can accommodate radical changes in social order. It begins by exposing a formalist stance that is immanent to much ‘legal activist’ discourse. It then explores links between this mode (...) of jurisprudential thought and idealist epistemology. Drawing from the philosophy of Theodor Adorno, and in particular his notion of ‘identity-thinking’, it uncovers structural connections between formalism, idealism, law and economy that call into question international law’s socially-transformative potential. The perspective advanced in this article falls somewhere between the polarities of opportunity and impasse, seeking to acknowledge the importance of legal strategies in safeguarding the disenfranchised, while remaining alive to their potential dangers and limitations.

Criminal liability for acts committed by AI systems has recently become a hot legal topic. This paper includes three different contributions. The first contribution is an analysis of the extent to which an AI system can satisfy the requirements for criminal liability: accomplishing an actus reus, having the corresponding mens rea, possessing the cognitive capacities needed for responsibility. The second contribution is a discussion of criminal activity accomplished by an AI entity, with reference to a recent case involving an online (...) bot, the Random Darknet Shopper. This discussion will provide the context for the analysis of commonalities and differences between criminal activities by humans and by artificial systems. The third contribution concerns the evaluation of different ways of addressing criminal activities by AI systems in a regulatory perspective. (shrink)

This chapter develops an account of the meaning and use of various types of legal claims, and uses this account to inform debates about the nature and normativity of law. The account draws on a general framework for implementing a contextualist theory, called 'Discourse Contextualism' (Silk 2016). The aim of Discourse Contextualism is to derive the apparent normativity of claims of law from a particular contextualist interpretation of a standard semantics for modals, along with general principles of interpretation and conversation. (...) Though the semantics is descriptivist, it avoids Dworkin’s influential criticism of so-called “semantic theories of law,” and elucidates the nature of “theoretical disagreements” about the criteria of legal validity. The account sheds light on the social, interpersonal function of normative uses of language in legal discourse. It also gives precise expression to Hart’s and Raz’s intuitive distinctions among types of legal claims (internal/external, committed/detached), while giving them a uniform type of analysis. The proposed semantics and pragmatics of legal claims provides a fruitful framework for further theorizing about the nature and metaphysics of law, the relation between law and morality, and the apparent practical character of legal language and judgment. Discourse Contextualism provides a solid linguistic basis for a broader account of legal discourse and practice. (shrink)

This paper studies how legal choices, and in particular legislative determinations, need to consider multiple rights and values, and can be assessed accordingly. First it is argued that legal norms (and in particular constitutional right-norms) often prescribe the pursuit of goals, which may be in conflict one with another. Then a model of teleological reasoning is brought to bear on choices affecting different goals, among which those prescribed by constitutional norms. An analytical framework is provided for evaluating such choices with (...) regard to possible alternatives. The assessment of legislative choices according to proportionality is then considered, and is modelled using the provided analytical framework. Finally, the framework is expanded to include the ideas of reasonableness and institutional deference, and the corresponding margins of appreciation. (shrink)

We shall introduce a set of fundamental legal concepts, providing a definition of each of them. This set will include, besides the usual deontic modalities (obligation, prohibition and permission), the following notions: obligative rights (rights related to other’s obligations), permissive rights, erga-omnes rights, normative conditionals, liability rights, different kinds of legal powers, potestative rights (rights to produce legal results), result-declarations (acts intended to produce legal determinations), and sources of the law.

The French and Dutch referenda on the adoption of a European Constitutional Treaty highlight a remarkable ambiguity in the self‐constitution of a polity, which can be viewed as both constitution by and of a collective self. This ambiguity is a fundamental feature of polities in general, and the European Union in particular. Rather than suppressing this ambiguity, democracy—and a fortiori a European democracy worth its name—institutionalises it as the guiding principle of political action. As will transpire, the conceptual and normative (...) problems raised by political self‐constitution are linked to self‐attribution, i.e., the conditions under which a collective ascribes legislation to itself.

The act of `setting the law' enjoys a central position in Kelsen's theory of authority. His analysis of this act criticizes, amongst others, the assumption of natural-law doctrines that norms are objective when they duplicate a content given directly to cognition and independently of the act whereby the norm is enacted. Correctly, Kelsen attacks the concept of representation underlying this assumption as an example of metaphysical dualism and a copy theory of knowledge. Does, then, an alternative understanding of authority require (...) scrapping representation from a theory of positive law? Or does it require interpreting representation differently? Following the second path, this paper reconstructs the act of setting the law in terms of the critical concept of representation developed by Ernst Cassirer and suggests how, thus reconstructed, the structure of this act can account for the law's authority and its contingency.

It appears at least intuitively appropriate to claim that we owe it to victims to punish those who have wronged them. It also seems plausible to state that we owe it to society to punish those who have violated its norms. However, do we also owe punishment to perpetrators themselves? In other words, do those who commit crimes have a moral right to be punished? This work examines the sustainability of the right to be punished from the standpoint of the (...) two main theories of rights—the will and the interest conceptions. The right to be punished is shown to be largely indefensible on both accounts: on the will theory, the right to be punished conflicts with autonomy, and it can neither be claimed nor waived by a perpetrator; on the interest theory, a perpetrator’s interest in punishment, inasmuch as it exists, is not sufficient to ground a duty on the part of the state.

The paper analyzes the sacred foundations of Western institutional order, moving from an epistemological, historical and legal–aesthetic perspective. Firstly, it identifies an epistemological theory of complexity which, pursuing Hayek’s theory of complexity, Robilant’s notion of informative–normative systems, Popper’s theory of the Worlds, and Dupuy’s theory of endogenous fixed point, will conclusively lead to presenting the hypothesis of World 0 as the World of the foundation of legal thinking, the home of the sacred and the aesthetic. Secondly, it identifies the axiological (...) character of the legal aesthetic as a discipline, a topic that will be taken up in relation to the work of the French historian of canonical law and psychoanalyst Legendre, starting from the analysis of a legal/historiographical context (Corpus Iuris Civilis, Corpus Iuris Canonici, Hobbesian Leviathan, Kelsenian Grundnorm). Thirdly, following Ellul’s thought on secularization, the idea that we now live in a secularized, lay society, lacking in the sacred is revealed as a sort of illusion, the creation of a myth of modernity, only apparently rational. Finally the paper proposes as the task of legal theory the identification of the system of “nomograms” in which the normative message is organized, according to a nonreductionistic approach that forces legal theory to recognize the plurality of the iconic forms of the normative message. The “nomograms” respond to the need of extending the field of legal science to phenomena that the positivist theory of law does not consider important, but which the process of evolution of contemporary society imposes.

Relationships between empirical and philosophical approaches to the law have not been always peaceful. Agreement seems the most natural way to build up and implementing regulations and justice within human-machine inter-faces (natural and artificial societies), and might help to bridge the gap between both theoretical approaches. Recent researches on relational law, relational jus-tice, crowdsourcing, regulatory systems and regulatory models are introduced. These concepts need further clarification, but they stand as political companions to more standard conceptions of law in the Semantic (...) Web. (shrink)

This paper discusses the main criticism launched against legal monism and the Pure Theory of Law, as envisaged by Hans Kelsen and the other proponents of the Vienna School of Jurisprudence, namely the criticism voiced by two of the most eminent legal theorists, HLA Hart and Joseph Raz. According to them, legal monism fails to offer a satisfactory theory of the identity of legal systems and it therefore simply cannot be considered a viable theory of legal systems, because it leads (...) to obviously absurd consequences. These arguments which take the form of an attack on the most basic tenets of the Pure Theory of Law and thus legal monism, will be duly addressed and consequently rebutted in this paper, particularly in order to be able to maintain legal monism in its juridico-epistemological manifestation as a working and viable theory of the law.

In this paper we provide a formal analysis of the idea of normative co-ordination. We argue that this idea is based on the assumption that agents can achieve flexible co-ordination by conferring normative positions to other agents. These positions include duties, permissions, and powers. In particular, we explain the idea of declarative power, which consists in the capacity of the power-holder of creating normative positions, involving other agents, simply by proclaiming such positions. In addition, we account also for the concepts (...) of representation, namely the representatives capacity of acting in the name of his principal, and of mandate, which is the mandatees duty to act as the mandator has requested. Finally, we show how the framework can be applied to represent the contract-net protocol. Some brief remarks on future research and applications conclude this contribution. (shrink)

One of the theoretical developments associated with the law of the European Union has been the flourishing of legal and constitutional theories that extol the virtues of pluralism. Pluralism in constitutional theory is offered in particular as a novel argument for the denial of unity within a framework of constitutional government. This paper argues that pluralism fails to respect the value of integrity. It also shows that at least one pluralist theory seeks to overcome the incoherence of pluralism by implicitly (...) endorsing monism. The integrity and coherence of European law is best preserved by considering that both the national legal order and the international or European legal orders adopt sophisticated views of their own limits.

This essay examines an ambiguity in Hans Kelsen’s theory of a norm. On the one hand, Kelsen claims to adhere to what he considers the ‘is/ought’ dichotomy. Kelsen claims that he is describing what really is. On the other hand, Kelsen seems to be understanding the is/ought dichotomy in a very different manner than that by which his contemporaries or, indeed, today’s readers understand the distinction. The clue to this ambiguity is Kelsen’s understanding of a norm. Although legal existence is (...) said to rest with norms, this existence is very different than an existence constituted from social behaviour. Instead, in Kelsen’s view, a norm is a signifying relation between a sign and a cognitive object. Kelsen’s theory of language, however, is very different from a theory of speech acts. When addressing why a norm is binding, we find that Kelsen’s full theory of language excludes important phenomena in order to retain its purity. (shrink)

In this essay both the facts/values and facticity/normativity divides are considered from the perspective of global semiotics and with specific regard to the relationships between legal meaning and spatial scope of law’s experience. Through an examination of the inner and genetic projective significance of categorization, I will analyze the semantic dynamics of the descriptive parts comprising legal sentences in order to show the intermingling of factual and axiological/teleological categorizations in the unfolding of legal experience. Subsequently, I will emphasize the translational (...) and enactive cognitive disposition underlying the construction of the second premise of the so-called judiciary syllogism and thereby the untenability of the idea that ‘law makes its facts.’ Hence, I will try to bring to the fore the cultural pre-assumptions encapsulated in the positivistic and therefore also formalistic or analytical approaches to legal experience and the loss of their inner consistency when legal experience confronts the phases and major changes of global semiotics. Finally, I will strive to relativize the opposition between the positivist and non-positivistic theories of law in view of an understanding of legal experience focused not only, or at least not primarily, on what ‘law is’ but also on ‘how’ it unwinds through, and _in spite of_, environmental and semantic transformations.

Law has variously been described as part of empirical social reality or as a set of normative prescriptions defining desirable conduct. The author takes the view that a legal system normally represents an amalgam of “is” and “ought” elements. It is operative in part as a living law of actual human conduct, in another part as an instrumentality for transforming unfulfilled social ideals or goals into reality. A different blending of “is” and “ought” factors often occurs in the judicial process, (...) when an application of given legal norms is combined with some injection of law deemed desirable by the judges.

The object of this paper is to throw light on the reciprocal exchanges between legal philosophy and the theory of speech acts (as developed by Austin and Searle). The first part concerns the contributions to legal philosophy made by the theory of speech acts with a view to developing new perspectives. The second part deals with the contributions of legal philosophy to speech act theory.

The argument of this article is that the dual-nature thesis is not only capable of solving the problem of legal positivism, but also addresses all fundamental questions of law. Examples are the relation between deliberative democracy and democracy qua decision-making procedure along the lines of the majority principle, the connection between human rights as moral rights and constitutional rights as positive rights, the relation between constitutional review qua ideal representation of the people and parliamentary legislation, the commitment of legal argumentation (...) to both authoritative and non-authoritative reasons, and the distinction between rules as expressing a real “ought” and principles as expressing its ideal counterpart. All of this underscores the point that the dual nature of law is the single most essential feature of law. (shrink)

Two claims lay the foundation for Beyleveld and Brownsword’s legal theory. The first says that immoral laws cannot be law, the second that rights to freedom and welfare can be proven to be logically necessary given merely the phenomenon of agency. The author argues that both claims are too strong. The first is an overidealization of law, which fails to do justice to its double nature as a real as well as an ideal phenomenon. The second must fail, for a (...) moral “ought” cannot be deduced from a merely instrumental “ought.”. (shrink)

The paper argues for viewing legal validity as a doxastic obligation, i.e. as the obligation to accept a rule in legal reasoning. This notion of legal validity is shown to be both sufficient for the laywers' needs and neutral in regard to various theories of the grounds of validity, i.e. theories intended to identify what rules are legally valid, by proposing different grounds for attributing validity. All of these theories, rather then being alternative definitions of validity, presuppose the notion here (...) provided.This notion is purely normative, but it allows for the construction of theories of the grounds of validity which give due importance to social expectations and institutions. As an example of how this may happen, one such theory is also provided. This theory, which is presented through a detailed example of a judicial debate, is based upon the recognition of the (instrumental) value of co-ordination, as the necessary way to achieve the most valuable purposes of the law.

. I will argue that the concept of law is a normative notion, irreducible to any factual description. Its conceptual function is that of relating certain properties a norm may possess to the conclusion that the norm is legally binding, namely, that it deserves to be endorsed and applied in legal reasoning. Legal validity has to be distinguished from other, more demanding, normative ideas, such as moral bindingness or legal optimality.

In institutional legal theory, norms and facts are reciprocally operating elements: an interplay in which meaning construction is closely connected with acting: the pragmatic understanding of legal language in terms of its uses. With the semiotic elements of institutional theory, extended by the notion of ‘semiotic groups’, an analytical framework can be constructed to analyze a case study on the shifts in the concept of war which have taken place since the 1945 UN Charter and in the aftermath of 9/11. (...) The semiotic aspects of the institutional approach can offer insight into the complexity of the processes of meaning attribution in the field of law and war. (shrink)

This article focuses on theoretical reflections on sovereignty and constitutionalism in the context of the globalization and Europeanisation of the nation states, their politics, and legal systems. Starting from a critical assessment of the Kelsen-Schmitt polemic, the author claims that sovereignty needs to be analysed by the sociological method in order to disclose its current structural differentiation. The constitution of society may be imagined as the multitude of self-constituted and functionally differentiated social subsystems. The constitutional pluralism argument subsequently reconceptualizes sovereignty (...) as socially differentiated and divided between specific subsystems. The EU's differentiated constitutional domain and the paradox of divided sovereignty are used as examples of profound structural and semantic changes in contemporary national and transnational societies. While the sovereign nation-state institutions have become marginalized in political structures of European societies, the self-constitutionalization of the functionally differentiated EU legal system proceeds by internalizing the concept of divided sovereignty and using it semantically as its mode of self-reference.

Abstract. In this paper I shall take an inferential approach to legality (legal validity), and consider how the legality of a norm can be inferred, and what can be inferred from it. In particular, I shall analyse legality policies, namely, conditionals conferring the quality of legality upon norms having certain properties, and I shall examine to what extent such conditionals need to be positivistic, so that legality is only dependant on social facts. Finally, I shall consider how legality is transmitted (...) from norm to norm and whether the ultimate legality policies (the rules of recognition) of a legal system need to be constituted by social facts.
