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.

John Searle’s The Construction of Social Reality and Hernando de Soto’s The Mystery of Capital shifted the focus of current thought on capital and economic development to the cultural and conceptual ideas that underpin market economies and that are taken for granted in developed nations. This collection of essays assembles 21 philosophers, economists, and political scientists to help readers understand these exciting new theories.

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)

Selon une thèse largement partagée, le droit et une pratique sociale et les contributions des participants sont complémentaires les unes des autres. Dans ces conditions, le raisonnement juridique consiste d’abord en une interprétation de ces pratiques et présuppose un point de vue interne de la part de celui qui souhaite en rendre compte. Le raisonnement juridique est ainsi conçu comme une argumentation pratique, subordonnée aux exigences de la rationalité car ceux qui participent à la pratique juridique sont contraints de donner (...) des raisons à leur action et ces raisons tissent un réseau de contraintes. Très séduisante, cette thèse qui doit beaucoup à la critique des réalistes par Hart, n’en demeure pas moins justiciable de quelque critique. (shrink)

This paper offers a diachronic reconstruction of MacCormick's theory of law and legal argumentation: In particular, two related points will be highlighted in which the difference between the perspective upheld in Legal Reasoning and Legal Theory and the later writings is particularly marked. The first point concerns MacCormick's gradual break with legal positivism, and more specifically the thesis that the implicit pretension to justice of law proves legal positivism false in all its different versions. The second point concerns MacCormick's acceptance (...) of the one-right-answer thesis and the consequent thinning of the differences between MacCormick's theory of legal reasoning and that of Ronald Dworkin and of Robert Alexy. The intent, however, is not only to describe this change in MacCormick's thought, but also to attempt a defence of the original view that we find in Legal Reasoning and Legal Theory. (shrink)

Several legal arguments use the notion of ratio legis in order to sustain a normative conclusion, in particular the argument from analogy and some forms of teleological argumentation. However, determining the ratio is often a difficult and controversial task. In this paper we look firstly at the speech acts typically performed by legal practitioners in order to determine the ratio and, secondly, we take into account the argumentative commitments they undertake in so doing and the argumentative constraints put on them. (...) This will lead us to distinguish different uses of the notion of ratio legis and to ask on what conditions each of them is justified. (shrink)

Sometimes established institutions aren’t perfect but cannot be replaced with better solutions. As technological, economic, ecological and other developments might indirectly further impair these imperfect institutions, non-change becomes normatively desirable and a practical challenge for legislators. In contrast to the progressive task of improving the established order, the task of preventing institutional achievements from being lost has been largely neglected by political theorists. To fill this lacuna, the article explores conservation as a mode of political action. It specifies the conditions (...) under which it is reasonable to oppose institutional innovation in politics in order to keep things as they are and develops a formal solution to Edmund Burke’s ‘conservation paradox’ in which existing arrangements can only stay the same if they are changed. The solution construes political conservation as renovative reformism that adapts institutional structures, cultures or mechanisms to changing circumstances in order to prevent indirect transformations of institutional mandates.

ABSTRACT:Although a research focus on the increasing involvement of corporations in shaping and maintaining the global rules of the game points out promising avenues for future research, it simultaneously makes clear how little currently established, mostly managerial conceptual frameworks have to offer in making sense of these developments. It is argued that we need to expand the rather restricted perspectives that these frameworks provide, in order to explore new conceptual foundations that will not only enable us to travel the confines (...) of the different disciplines involved with the study of the changing role of business in shaping the global rules of the game, but that can also systematically connect normative and positive research questions at the conceptual level. Three directions for this search for new foundations are briefly explored. (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.

This article develops a model first proposed in my book Jurisprudence and communication [67]. It takes as its starting point the generally conception that legal rules are valid norms, involving a normative content and expressing themselves in reality through observable conduct. This dualistic character of law is central. Law is both fiction and factual, ideal and real. But the viewpoint that a legal rule is a manifestation of validity in reality, through empirical acts, raises the question how rules as (valid) (...) fictions can be known and understood in their linguistic form. How is meaning attributed to the legal words and how do these words relate to the world of fact? Taking an institutional-pragmatic approach as a starting point, an analytical model is created that can be used as an instrument for the relationship between legal rules as thought objects existing only in the mind, and legal rules as observable conduct. This model seeks to revise the classical models of legal communication that basically focus on the unilateral flow of legal information between ‘senders and receivers’ and their claim of linear causality between rules and conduct. The model here constructed in the theoretical part is then applied to several case studies, in order to analyze the construction of meaning in actual use. Two fundamental rights—the older codified in 1798 and the more recent codified in 1983—in the Dutch Constitution have been analyzed using the model as an instrument. Further, the remarkable shifts in article 96 of the Constitution, the declaration of war, and its consequences, resulting in a new category of war—the armed conflict—have been analyzed, as well as the phenomenon of ‘peacekeeping missions’ involving actual warfare. The new war terminology has created vagueness with respect to the clear-cut division between war and peace, which has been reflected in several cases before Court, including the Eric O. case. The present analysis of the case studies indicates that the model was not in all cases completely tailored to the facts: for example, in the case study on article 96 a broad spectrum of observable legal and non-legal actors dominated the facts in such a way that the model did not fully cover it. The observations on my book by the three respondents in this special issue have contributed to the adaptation and extension of the model. In the Postscript my responses suggest some ways in which their ideas can be implemented. (shrink)
