Hart proposed that law is made possible by the practice among legal officials of observing conventional social rules, the most important being rules of recognition. This view has been dubbed the practice theory, and it has been attacked by many legal theorists. This paper argues that many criticisms of the practice theory fail because they misunderstand the nature of the organizational challenge to which rules of recognition are the solution. The challenge of constituting a legal system is essentially the challenge (...) of constituting a group agent, and when viewed through Pettit’s account of group agency, the practice theory can easily be defended.

H. L. A. Hart proposed one of the most influential accounts of law, according to which law is a union of primary rules, which guide the behavior of the law’s subjects, and secondary rules, which guide officials in recognizing, changing, and interpreting primary rules. Writing at the end of the 1950s, Hart had serious doubts about whether international law meets the necessary criteria for a legal system. But there are several reasons to reconsider his position. One is that international law (...) has grown significantly since then, but a more important reason is that Hart provided an oversimplified description of the necessary and sufficient conditions for law provided by his account, and therefore of the nature of the international legal order. A proper understanding of Hart’s view gives us a richer and more accurate understanding of the essential features of law, but also a less precise yardstick by which to measure and characterize the various systems of rules, including international law. According to this new yardstick, international law fails to meet the criteria for a Hartian legal system, but for reasons other than those identified by Hart. (shrink)

This paper seeks to uncover and rationally reconstruct four theoretical prescriptions that H. L. A. Hart urged philosophers to observe and follow when investigating and theorizing about the nature of law. The four prescriptions may appear meager and insignificant when each is seen in isolation, but together as an inter-connected set they have substantial implications. In effect, they constitute a central part of Hart’s campaign to put philosophical investigations about the nature of law onto a path to a genuine research (...) program. The paper takes note of certain prevalent and robust trends in contemporary legal philosophy that detract its practitioners from the four prescriptions, and that have them revert to the some older modes of thinking from which Hart sought a decisive break. A number of contemporary legal philosophers’ views and commitments are taken up and assessed, and in particular those of John Gardner and Leslie Green. (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.

En este artículo exploro algunos de los tópicos vinculados tradicionalmente con el problema de la normatividad del derecho: autonomía, racionalidad, relevancia práctica, razones para la acción y autoridad. Trataré de construir un marco conceptual que refleje la complejidad teórica del problema y las posiciones filosóficas desde los cuales puede ser abordado. Particularmente, me centraré en el análisis de las asunciones filosóficas relacionadas con ciertas posturas y la revisión de su coherencia mutua.
