The article examines recent theories of legal and constitutional pluralism, especially their adoption of sociological perspectives and criticisms of the concept of sovereignty. The author argues that John Griffiths's original dichotomy of “weak” and “strong” pluralism has to be reassessed because “weak” jurisprudential theories contain useful sociological analyses of the internal differentiation and operations of specific legal orders, their overlapping, parallel validity and collisions in global society. Using the sociological methodology of legal pluralism theories and critically elaborating on Teubner's societal (...) constitutionalism, the author subsequently reformulates the question of sovereignty as a sociological problem of complex power operations communicated through the constitutional state's organization and reconfigured within the global legal and political framework.

Robert Alexy has built his original theory of law upon pervasive claims for “necessary” features of law. In this article, I show that Alexy's claims suffer from two difficulties. First, Alexy is never clear about what he means by “necessity.” Second, Alexy writes as if there have been no challenges to claims of conceptual necessity. There have been such challenges and Alexy needs to answer them if his project is to succeed.

Law contains many dualities, though most, if not all, of these dualities resolve into one complex puzzle: To what extent is law a matter of pure social facts, or moral value untethered to social facts? I argue that each concept of law reconciles this duality in a different way on the basis of certain beneficial consequences that might result. Instead of pitting concepts against one another universally, we should accept that the balance between law's social fact and moral value dimensions (...) is context-specific in relation to particular legal puzzles. This balance can be achieved only by considering both political theory and empirical data. (shrink)

For any type of institutionalized dispute resolution, legitimacy is a crucial characteristic, as legitimate dispute resolution promotes, for instance, general trust in state institutions and participation in economic activity. A lack of legitimacy will prevent the acceptance of dispute resolution, and thereby its use. Although many textbook definitions limit the meaning of legitimacy to legality, in its every-day use legitimacy is in fact a much broader concept. It encompasses different criteria relating to the nature of dispute resolution: is a form (...) of dispute resolution properly embedded in a reliable institutional environment?, and: are its outcomes properly underpinned? Virtualization concerns the ways in which information and communication technologies affect administration, communication, accessibility and assessment. As an example of virtualization in dispute resolution, a scenario about on-line feedback is scrutinized. This scenario comprises the implementation of a feedback system to enable participants in an instance of dispute resolution to comment on various aspects of the dispute resolving process. (shrink)

This article aims at contributing to the discussion about the relationships between ICT, computer science and policy-making by focusing on agent-based social simulation. Enabled, from a technical point of view, by the developments of Distributed Artificial Intelligence in the 1990s and by the features of the object-oriented programming paradigm, agent-based social simulations are a tool for the analysis of social dynamics that can be used also to support the design and the evaluation of public policies. After a brief description of (...) social simulation paradigm and of its impact on social sciences, the paper presents a simple agent-based model devised to analyze, even if in a very abstract way, a phenomenon that can rouse the interest of legal scientists: the interplay between damaging behaviors, punishment and social mechanisms of learning and imitation. Our goal is to show how agent-based simulation can be used not only to illuminate basic mechanisms underlying social phenomena but also to reflect, in an innovative way, on how society can deal with them.

American legal realism is commonly treated as a theory-pariah. The article exposes certain reasons explaining such a treatment. Generally, it seems that such an attitude is a result of many misunderstandings of realist aims and ambitions, some of which pertain to the theoretical status of legal realism and its relation to so called general jurisprudential theories, such as legal positivism. In the first part of the article I explain generally what these aims were and how one should see these relations. (...) In the second part I briefly analyze B. Leiter’s famous claim that legal realism is conceptually dependent on hard legal positivism (as a general theory of law). The critique of this claim opens the possibility for some alternative understanding of legal realism. (shrink)

This article examines two modalities of law, depicted spatially as the vertical and the horizontal. The intellectual background for seeing law in vertical and horizontal dimensions is to be found in much socio-legal scholarship. These approaches have challenged the modernist, legal positivist and essentially vertical view of law as a system of imperatives emanating from a hierarchically superior source such as a sovereign. In keeping with the socio-legal critical tradition, but approaching it from the perspective of legal philosophy, my aim (...) is to address three matters. First, why is vertical law problematic for feminists? Second, what are the theoretical characteristics of law in its horizontal register? Third, how is an appreciation of this ‘flat’ law useful for feminist legal theory and practice? In particular, I consider the ways in which feminist legal theory operating in the horizontal dimension can transgress, without transcending, the vertically determined perimeters of the nation state.

The proliferation of forms of transnational regulation, often unclear in their relation to the law of nation states but also, in some cases, claiming authority as “law,” suggests that the concept of law should be reconsidered in the light of processes associated with globalisation. This article identifies matters to be taken into account in any such reconsideration: in particular, ideas of legal pluralism, of degrees of legalisation, and of relative legal authority. Regulatory authority should be seen as ultimately based in (...) the diverse moral conditions of the networks of community which regulation serves. (shrink)

This article is about ‘role responsibility’ as understood by H. L. A. Hart in his taxonomy of responsibility concepts in his book, Punishment and Responsibility. More particularly, it focuses on what I call ‘public, institutional role responsibility’. The main arguments are that such role responsibility is based on authority and power rather than physical and mental capacity; and the foundation of role responsibility in authority has significant implications for what Hart referred to as ‘liability–responsibility’, which I unpack in terms of (...) ‘attribution’, ‘accountability’ and ‘liability’. The article addresses possible objections to the authority-based analysis of role responsibility based on the concept of ‘moral’ responsibility, and on understandings of what types of question are ‘philosophical.’.
