I here address the question of how judges should decide questions before a court in morally imperfect legal systems. I characterize how moral considerations ought inform judicial reasoning given that the law may demand what it has no right to. Much of the large body of work on legal interpretation, with its focus on legal semantics and epistemology, does not adequately countenance the limited legitimacy of actual legal institutions to serve as a foundation for an ethics of adjudication. I offer (...) an adjudicative theory in the realm of non-ideal theory: I adopt a view of law that has achieved consensus in legal philosophy, make some plausible assumptions about human politics, and then consider directly the question of how judges should reason. Ultimately, I argue that judges should be cognizant of the goods that are at stake on particular occasions of adjudication and that this requires treating legal requirements transparently, i.e., as sensitive to their moral justifications.

Judicial obligation to enforce the law is typically regarded as both unproblematic and important: unproblematic because there is little reason to doubt that judges have a general, if prima facie, obligation to enforce law, and important because the obligation gives judges significant reason to limit their concern in adjudication to applying the law. I challenge both of these assumptions and argue that norms of political legitimacy, which may be extra-legal, are irretrievably at the basis of responsible judicial reasoning.

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)

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)

This paper guides the reader through the use of functions in contemporary legal philosophy: in developing those philosophies and through methodological debates over their proper role. This paper is broken into two sections. In the first I canvass the role of functions in the legal philosophies of several mid to late twentieth century Anglo-American general jurisprudents whose theories are still common topics of discussion: Ronald Dworkin, H.L.A. Hart, Lon L. Fuller, John Finnis, and Joseph Raz. In the second, I examine (...) contemporary arguments over the role of functions in the methodology of legal philosophy. (shrink)

The practical, normative dimension of planning is a plausible source of the ‘family resemblances’ noted by a number of legal theorists between Scott Shapiro’s Planning Theory and natural law jurisprudence. Foremost among these resemblances is Shapiro’s contention that the law, necessarily, has a moral aim. The moral aim thesis is at first glance surprising given Shapiro’s intention to defend exclusive legal positivism and unequivocal rejection of what he takes to be the core commitments of natural law theory. Shapiro’s claim, however, (...) is that although the law necessarily has a moral aim, this does not entail that it is successful in satisfying that aim. In order to assess this thesis, it is helpful to compare the Planning Theory with contemporary natural law approaches. Bringing Shapiro’s Planning Theory into dialogue with contemporary natural law theories can demonstrate some of the Planning Theory’s weaknesses as an alternative explanation of the ultimate grounds of the authoritativeness of legal norms. Some of these weaknesses, moreover, are instructive beyond the specific contours of the Planning Theory insofar as they generalise to other legal positivist approaches. In section one I consider Shapiro’s treatment of the so-called ‘Possibility Puzzle’ regarding the grounding relation between authoritative norms and legal authority. Shapiro’s denial of the capacity of earlier jurisprudential theories to resolve this puzzle overlooks what is – I suggest – a plausible solution developed by John Finnis on the basis of Joseph Raz’s theory of practical reason and norms. Section two then demonstrates why Shapiro’s attempt to combine a robust construal of the social facts thesis with a commitment to the thesis that law necessarily has a moral aim is ultimately unsuccessful.

This article considers natural law perspectives on the nature of law. Natural law theories are united by what Mark Murphy calls the natural law thesis: law is necessarily a rational standard for conduct. The natural law position comes in strong and weak versions: the strong view holds that a rational defect in a norm renders it legally invalid, while the weak view holds that a rational defect in a legal norm renders it legally defective. The article explores the motivations for (...) the natural law position, before considering three lines of natural law argument found in the literature. I conclude by examining the arguments offered by John Finnis and Murphy in support of the weak natural law view. I suggest that these arguments fail to impugn the strong natural law thesis. Indeed, the functional argument outlined by Murphy provides a plausible route to a hybrid natural law view that incorporates both weak and strong claims. (shrink)

Natural law theories affirm that it belongs to the nature of law to be apt to promote the common good or do something similar. I defend a weak version of this thesis according to which part of what constitutes something as a nondefective central case of a posited law is that it is apt to promote the common good. Just as the rules of Pictionary require the drawing player to design her drawing to reveal the word in play, the rules (...) of a central case of a legal system require lawmakers to design laws to promote the common good. Therefore, just as a Pictionary drawing that is inapt to reveal the word in play is defective, a central case of a posited law that is inapt to promote the common good is defective. (shrink)

This paper offers a critical assessment of the way the influential “conception of law as a shared activity” explains the normative component of law in general and legal obligation in particular. I argue that the conception provides a bipartite account of legal obligation: we have full-blooded legal obligation, carrying genuine practical force, and legal obligation in a perspectival sense, the purpose of which is not to engage with us in practical reasoning, but simply to state what we ought to do (...) if we should take the perspective of individuals subject to the jurisdiction of the legal system. This structural feature makes the whole account disjointed, giving it a lack of unity from which stem what I take to be its three main problems, namely, its limited scope, its failure to recognize the moral features of obligation when made to arise out of law as a shared activity, and its failure to illustrate the sense in which law is widely recognized to be a practical institution.
