Decision-making by a Data and Safety Monitoring Board (DSMB) regarding clinical trial conduct and termination is intricate and largely limited by cases and rules. Decision-making by legal jury is also intricate and largely constrained by cases and rules. In this paper, I argue by analogy that legal decision-making, which strives for a balance between competing demands of conservatism and innovation, supplies a good basis to the logic behind DSMB decision-making. Using the doctrine of precedents in legal reasoning as my central (...) analog will lead us to a decision-theoretic analogy for much more systematic documentation of decisions in clinical trials. My conclusion is twofold: every DSMB decision should articulate a clear general principle (a ratio decidendi) that gives reason for the decision; and all such decisions should be made public. I use Bartha’s (2010) theory of analogical arguments to both frame and assess my argument by analogy. (shrink)

For much of the first fifty years of its existence, analytic philosophy shunned discussions of normativity and ethics. Ethical statements were considered as pseudo-propositions, or as expressions of pro- or con-attitudes of minor theoretical significance. Nowadays, in contrast, prominent analytic philosophers pay close attention to normative problems. Here we focus our attention on the work of Searle, at the same time drawing out an important connection between Searle’s work and that of two other seminal figures in this development: H.L.A. Hart (...) and John Rawls. We show that all three thinkers tend to assume that there is but one type of normativity within the realm of social institutions – roughly, the sort of normativity that is involved in following the results of chess – and that they thereby neglect features that are of crucial significance for an adequate understanding of social reality.

Time is central to Luhmann’s writings on social systems. Social systems, as systems of meaning, operate within three dimensions: factual, social and temporal. Each of these dimensions entails selections of actualities from potentialities (or contingencies) within horizons. Whilst the factual dimension involves selections based on distinguishing ‘this’ from ‘something else’, and the social distinguishes between alter and ego (asking with respect to any meaning whether another experiences it as I do), the temporal dimension operates with the primary distinction of before (...) and after. In the temporal dimension, everything is ‘ordered only according to the when and not to the who/what/where/how of experience and action’ (Luhmann in Social systems. Stanford University Press, Stanford, 1995, p. 78). In this paper, we explore the connection between the temporal dimension of meaning within the legal system and its connection to justice. We begin by setting out succinctly the role played by justice within the legal system, as presented by Luhmann, particularly in his book Law as a social system (2004). From this beginning, we move on to consider the relationship between law, justice and time, taking two examples. The first is the temporality of judicial decisions. The second concerns the relationship between the temporal meaning of law’s own operations, and the presumption of innocence. (shrink)

Some theorists believe that there is a plurality of values, and that in many circumstances these values are incommensurable, or at least incomparable. Others believe that all values are reducible to a single super-value, or that even if there is a plurality of irreducible values these values are commensurable. But I will argue that both sides have got it wrong. Values are neither commensurable nor incommensurable, at least not in the way most people think. We are free to believe in (...) incommensurability or not, depending on what particular conception of morality we want to embrace. Incommensurability is accordingly not a theory about value. It is a presupposition that provides a necessary background condition for a certain kind of value to exist. It is therefore not the kind of view that can be morally true or false. As a presupposition, it can only be accepted or rejected on grounds that do not presuppose that morality already exists. Incommensurability is, like the rejection of hard determinism, one of the presuppositions on which morality as we know it happens to be based. (shrink)

The reform of offenders is often said to be one of the morally legitimate aims of punishment. After briefly surveying the history of reformist thinking I examine the ‘quasi-reform’ theories, as I call them, of H. Morris, J. Hampton and A. Duff. I explain how they conceive of reform, and what role they take it to have in the criminal justice system. I then focus critically on one feature of their conception of reform, namely, the claim that a reformed offender (...) will obey the relevant laws for moral reasons. I argue on consequentialist grounds that this requirement is objectionable. Consequentialism has always accepted reform as one legitimate goal of punishment, but it will not accept the narrowly moral conception of it that we find in the quasi-reform theorists. I situate my criticism within criminal law theory, but I also consider the claim in moral theory that acting from moral motives has intrinsic value. (shrink)

Both the traditional Aristotelian and modern symbolic approaches to logic have seen logic in terms of discrete symbol processing. Yet there are several kinds of argument whose validity depends on some topological notion of continuous variation, which is not well captured by discrete symbols. Examples include extrapolation and slippery slope arguments, sorites, fuzzy logic, and those involving closeness of possible worlds. It is argued that the natural first attempts to analyze these notions and explain their relation to reasoning fail, so (...) that ignorance of their nature is profound. (shrink)

Though political philosophers often presuppose that coercive enforcement is fundamental to law, many legal philosophers have doubted this. This article explores doubts of two types. Some legal philosophers argue that given an adequate account of coercion and coerciveness, the enforcement of law in actual legal systems will generally not count as coercive. Others accept that actual legal systems enforce many laws coercively, but they deny that law has a necessary connection with coercion. There can be individual laws that lack coercive (...) sanctions, and it is at least conceptually possible for there to be a legal system that lacks coercive enforcement altogether. This article then examines why most political philosophers and some legal philosophers have been reluctant to treat the conceptual possibility of non-coercive law as significant. (shrink)

Robert Alexy defines law as including a claim to moral correctness and demonstrating social efficacy. This paper argues that law's social efficacy is not merely an observable fact but is undergirded by moral commitments by rulers that it is possible for their subjects to follow the rules, that the rulers and others will also follow the rules, that subjects will be protected from violence if they act in accordance with the rules, and that subjects will be entitled to legal redress (...) if others act violently towards them otherwise than in accordance with the rules. Alexy is correct in his conclusion that a system of norms that is not by and large socially efficacious is not a valid legal system, but wrong insofar as he follows legal positivism in distinguishing this aspect of law's validity from law's claim to moral correctness.

This paper gives an account of proxy agency in the context of collective action. It takes the case of a group announcing something by way of a spokesperson as an illustration. In proxy agency, it seems that one person or subgroup's doing something counts as or constitutes or is recognized as (tantamount to) another person or group's doing something. Proxy agency is pervasive in institutional action. It has been taken to be a straightforward counterexample to an appealing deflationary view of (...) collective action as a matter of all members of a group making a contribution to bringing about some event. I show that this is a mistake. I give a deflationary account of constitutive rules in terms of essentially collective action types. I then give an account of one form of constitutive agency in terms of constitutive rules. I next give an account of status functions—of which being a spokesperson is one—that also draws on the concept of a constitutive rule. I then show how these materials help us to see how proxy agency is an expression of the agency of all members of the group credited with doing something when the proxy acts. (shrink)

What constitutes numerically one and the same tradition diachronically, at different times? This question is the focus of often violent dispute in societies. Is it capable of a rational resolution? Many accounts attempt that resolution with a diagnosis of ambiguity of the disputed concept-Islam, Marxism, or democracy for example. The diagnosis offered is in terms of vagueness, namely the vague criteria for sameness or similarity of central beliefs and practices.

We provide a retrospective of 25 years of the International Conference on AI and Law, which was first held in 1987. Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections. As a whole, the subsections build into (...) a history of the last quarter century of the field, and provide some insights into where it has come from, where it is now, and where it might go.

This paper considers whether the positivist account of law is useful in guiding states in how they should deal with religious or customary legal orders followed by minority groups within their jurisdiction. It argues, first, that such orders can be said to exist despite the prevalence of disagreement about the grounds of law. It then argues, contrary to views advanced by Scott Shapiro and Joseph Raz, that there are good reasons for perceiving that the resolution of legal disputes by reference (...) to moral principle involves the application of pre‐existing law. However, the paper concludes by arguing that the Social Thesis has an important role in supplying the basis upon which the application of law can be deemed to be legitimate, and that this has relevance to the way states might respond to minority legal orders.

This paper is intended to be a summary of the author's views on the relationship between law and morality worked out over the past three decades in jurisprudence. The paper preliminarily clarifies the matter by isolating some lines of cleavage separating different questions askable about this relationship. With this done, the author argues for two theses. One, that judges are obligated to use morality in their decisions in particular cases; and two, that the morality judges are obligated to use in (...) their judicial reasonings, is best seen as the natural lawyer sees it, namely, as being part of the law that obligates judges in their role as judges. The author not only believes these theses to be true; he also thinks that these theses are practically important, in that their acceptance by judges makes for better judging. (shrink)

The Dutch education system relies upon a large number of publicly-subsidized, denominational schools. The authors defend the importance of schools that educate children within a specific — including denominational — conception of the good by arguing for the importance of such a conception for the development of the child's identity. An essential component of this developmental process is critical reflection, conceived as crucial to the formation of moral autonomy.

A communitarian perspective, which is characteristic of African normative thought, accords some kind of primacy to society or a group, whereas human rights are by definition duties that others have to treat individuals in certain ways, even when not doing so would be better for others. Is there any place for human rights in an Afro-communitarian political and legal philosophy, and, if so, what is it? I seek to answer these questions, in part by critically exploring one of the most (...) influential theoretical works on human rights in a sub-Saharan setting, namely, Claude Ake’s ‘The African Context of Human Rights’. Ake famously maintains that a typically Western approach to rights is inappropriate in the sub-Saharan region, in two major respects. First, Ake contends that although a human rights legal framework might be suitable for an ‘individualistic’ society, it is not for one of the sort common among traditional black peoples, for whom group rights are alone apt. Second, Ake maintains that, insofar as rights are relevant, rights to socio-economic goods are of much more importance in an African context than rights to civil liberties, due process and the like. Using Ake’s article as a foil, I draw on values salient in sub-Saharan moral worldviews to construct a unified philosophy of rights that not only provides reason to doubt his two claims, but also offers a promising way to reconcile a communitarian framework with a robust prizing of human rights alongside ones that are more collectively oriented. In short, I aim to provide a principled foundation for the core elements of the African Charter of Human and Peoples’ Rights. (shrink)

Constitutional pluralism has become a principal model for understanding the legal and political structure of the European Union. Yet its variants are highly diverse, ranging from moderate “institutional” forms, closer to constitutionalist thinking, to “radical” ones which renounce a common framework to connect the different layers of law at play. Neil MacCormick, whose work was key for the rise of constitutional pluralism, shifted his approach from radical to institutional pluralism over time. This paper reconstructs the reasons for this shift—mainly concerns (...) about political stability that also underlie many others' skepticism vis-à-vis radical pluralist ideas. It then seeks to show why such concerns are likely overdrawn. In the fluid, contested space of postnational politics, a common, overarching frame is problematic as it might inflame, rather than tame, tensions. Leaving fundamental issues open along radical pluralist lines may help to work around points of highly charged contestation and provide opportunities for resistance from less powerful actors.

This paper adopts a legal perspective to counter some exaggerations of today’s debate on the social understanding of robotics. According to a long and well-established tradition, there is in fact a relative strong consensus among lawyers about some key notions as, say, agency and liability in the current use of robots. However, dealing with a field in rapid evolution, we need to rethink some basic tenets of the contemporary legal framework. In particular, time has come for lawyers to acknowledge that (...) some acts of robots should be considered as a new source of legal responsibility for others’ behaviour. (shrink)

This article addresses the question of whether judges can take the internal point of view towardtheir legal system's rule of recognition for purely prudential reasons. It takes a fresh look at an underappreciated conceptual argument of Joseph Raz's that answers: no. In a nutshell, Raz argues that purely prudential reasons are reasons of the wrong kind for judges to accept their legal system's rule of recognition. And should Raz's argument succeed, an important necessary connection between law and morality would be (...) established. (shrink)

I seek to advance enquiry into the philosophical question of in virtue of what human beings have a dignity of the sort that grounds human rights. I first draw on values salient in sub-Saharan African moral thought to construct two theoretically promising conceptions of human dignity, one grounded on vitality, or liveliness, and the other on our communal nature. I then argue that the vitality conception cannot account for several human rights that we intuitively have, while the community conception can (...) do so. I conclude that, of plausible theories of human dignity with an African pedigree, the field ought to favour a community-based view and critically compare it in future work with the Kantian, autonomy-based view that dominates Western thinking about dignity.

Islamic building codes require mosques to face Mecca. The further Islam spreads, the more apt are believers to fall into a quandary. X faces Y only when the front of X is closer to Y than any other side of X. So the front of the mosque should be oriented along a shortest path to Mecca. Which way is that? Does the path to Mecca tunnel through the earth? Or does the path follow the surface of the earth?

It is not clear, on the face of it, whether Thomas Hobbes's legal philosophy should be considered to be an early example of legal positivism or continuous with the natural-law tradition. On the one hand, Hobbes's command theory of law seems characteristically positivistic. On the other hand, his conception of the "law of nature," as binding on both sovereign and subject, seems to point more naturally toward a natural-law reading of his philosophy. Yet despite this seeming ambiguity, Hobbes scholars, for (...) the most part, have placed him within the legal-positivist tradition. Indeed, Hobbes is usually regarded as the father of legal positivism. Recently, however, a growing number of commentators has begun to question this traditional classification. Although it is clear that Hobbes is not a natural lawyer of the same mold as Thomas Aquinas, it is, nevertheless, increasingly becoming evident that the traditional characterization of Hobbes as a positivist in the same vein as Jeremy Bentham or John Austin is also incorrect. There are important naturallaw aspects of Hobbes's view that one ignores only at the cost of a proper understanding of his theory of law. (shrink)

Two recent discussions concerning punishment of the socially deprived reach conflicting conclusions. Andrew von Hirsch and Andrew Ashworth argue that we should sympathize with the predicament of the poor and therefore mitigate their sentences. Peter Chau disputes von Hirsch and Ashworth’s conclusion, contending that having to face strong temptations is not an appropriate ground for reducing anyone’s punishment for their crimes. I argue that neither von Hirsch and Ashworth’s account nor Chau’s critique of it is persuasive. I then take up (...) the challenge of showing why social deprivation renders punishment problematic. I contend that it establishes a perverse incentive structure that is persistent and powerful, requiring the disadvantaged to exercise self-control on an ongoing basis. Repeated acts of self-control are difficult, especially for youths whose skills at it are not yet fully developed. Also, in a variety of more and less subtle ways, social deprivation reduces the incentives for self-control and may work to stunt its development. In closing, I briefly consider the options for responding to the crimes of the chronically disadvantaged. (shrink)

Assuming that legal science, specifically with regard to interpretation, has to provide the tools to reduce the uncertainty of legal solutions arising from the use of natural languages by legal orders, it becomes a central matter to identify, in this limited domain, the spectrum of semantic variation (and its boundaries) that language brings to the definition of a norm expressed by a norm sentence. It is in this framework that the present paper, analyzing norm sentences as a specific kind of (...) speech act, examines the relation of the legal order to natural language rules, the limits of linguistic uncertainty, and alternatives of meaning as distinct possibilities of norms covered by the text (that are, because of this, still within what literal meaning is). Considering interpretation just as the linguistic decoding process, the reverse of the process of creating norm sentences, the paper also argues that subjects not connected with the relation between norm sentences and norms (mainly, normative defeasibility) are analytically distinct and should be removed from the field of language.

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)

In order to present a hopefully comprehensive framework of what is the stake of the growing use of robot soldiers, the paper focuses on: the different impact of robots on legal systems, e.g., contractual obligations and tort liability; how robots affect crucial notions as causality, predictability and human culpability in criminal law and, finally, specific hypotheses of robots employed in “just wars.” By using the traditional distinction between causes that make wars just and conduct admissible on the battlefield, the aim (...) is to clarify how advancement of military robotics technology is transforming a 2,000-year-old legal debate on the concept of “just war.” For the first time, legal systems will hold political authorities and military commissioners responsible for what an artificial soldier autonomously decides to do. The paper examines how the new scenario affects both principles of military conduct and notions of justice in resorting to war. (shrink)

What is the relation between norms (in the sense of ?socially accepted rules?) and conventions? A number of philosophers have suggested that there is some kind of conceptual or constitutive relation between them. Some hold that conventions are or entail special kinds of norms (the ?conventions-as-norms thesis?). Others hold that at least some norms are or entail special kinds of conventions (the ?norms-as-conventions thesis?). We argue that both theses are false. Norms and conventions are crucially different conceptually and functionally in (...) ways that make it the case that it is a serious mistake to try to assimilate them. They are crucially different conceptually in that whereas conventions are not normative and are behaviour dependent and desire dependent, norms are normative, behaviour independent, and desire independent. They are crucially different functionally in that whereas conventions principally serve the function of facilitating coordination, norms principally serve the function of making us accountable to one another.

Feizi 韓非子 in terms of the concept of shi 勢 (circumstantial advantage, power, or authority). This argument is based on the A Critique of Circumstantial Advantage (Nanshi 難勢) chapter of the Hanfeizi, where Han Feizi advances his own idea of shi after criticizing both Shen Dao and an anonymous Confucian. However, there are other primary sources to contain Shen Dao’s thought, namely, seven incomplete Shenzi 慎子 chapters of the Essentials on Government from the Assemblage of Books (Qunshu zhi yao 群書治要) (...) and other fragments preserved in other Chinese texts. This article examines the Shenzi fragments in order to ask whether Shen Dao stresses the concept of shi. (shrink)

National legal systems undergo profound changes when they are confronted with undemocratic power seizure. The same occurs when they experience a transition (back) to democracy. Thus far, these two types of transition have been studied in relative isolation. Nevertheless, it seems that both undemocratic usurpers and democratizing regimes affect the role of fundamental rule-of-law principles in similar ways. This article compares both types of transition and suggests that pragmatism and national identity are the driving forces behind similar legal mechanisms, affecting (...) legal principles, in those two forms of transition. Drawing on Carl Schmitt's idea of the state of exception and Ruti Teitel's work on transitional justice, this article shows that both kinds of transition share the same fundamental legal structure.

I argue that law is not best considered an essentially contested concept. After first explaining the notion of essential contestability and disaggregating the concept of law into several related concepts, I show that the most basic and general concept of law does not fit within the criteria generally offered for essential contestation. I then buttress this claim with the additional explanation that essential contestation is itself a framework for understanding complex concepts and therefore should only be applied when it is (...) useful to gain a greater understanding of uses of the concept to which it is applied (adducing criteria for making such judgments of usefulness). With that in mind, I then show that applying the appellation of essential contestation to the concept of law does not helpfully illuminate the most general concept of law (usually of most interest to legal philosophers) and therefore it should not be used, while allowing that it might be more useful for the related concept of the rule of law.

Some legal theorists deny that states can conceivably act extra-legally, in the sense of acting contrary to domestic law. This position finds its most robust articulation in the writings of Hans Kelsen, and has more recently been taken up by David Dyzenhaus in the context of his work on emergencies and legality. This paper seeks to demystify their arguments and, ultimately, contend that we can intelligibly speak of the state as a legal wrongdoer or a legally unauthorized actor.

There are many ways to avoid responsibility, for example, explaining what happens as the work of the gods, fate, society, or the system. For engineers, “technology” or “the organization” will serve this purpose quite well. We may distinguish at least nine (related) senses of “responsibility”, the most important of which are: (a) responsibility-as-causation (the storm is responsible for flooding), (b) responsibility-as-liability (he is the person responsible and will have to pay), (c) responsibility-as-competency (he’s a responsible person, that is, he’s rational), (...) (d) responsibility-as-office (he’s the responsible person, that is, the person in charge), and (e) a responsibility-as-domain-of-tasks (these are her responsibilities, that is, the things she is supposed to do). For all but the causal sense of responsibility, responsibility may be taken (in a relatively straightforward sense)—and generally is. Why then would anyone want to claim that certain technologies make it impossible to attribute responsibility to engineers (or anyone else)? In this paper, I identify seven arguments for that claim and explain why each is fallacious. The most important are: (1) the argument from “many hands”, (2) the argument from individual ignorance, and (3) the argument from blind forces. Each of these arguments makes the same fundamental mistake, the assumption that a certain factual situation, being fixed, settles responsibility, that is, that individuals, either individually or by some group decision, cannot take responsibility. I conclude by pointing out the sort of decisions (and consequences) engineers have explicitly taken responsibility for and why taking responsibility for them is rational, all things considered. There is no technological bar to such responsibility. (shrink)

There is a vast literature on the meanings of legal penalties. However, we lack a theory that explains them according to the formation of the modern state. Oakeshott's theory can help explain this phenomenon, leading to an attempt of the individual to take over as many powers of the state as possible. Thus, Kant's and Smith's retributivism is the most consistent of all those theories. Nevertheless, the preventive and resocializing theory of Bentham succeeded eventually. But is this a liberal theory? (...) We contrast the explanations of H.L.A. Hart and Frederick Rosen in order to lay the groundwork for a liberal theory of the meaning of legal sanctions. (shrink)

An account of the ontological nature of collectives would be useful for several reasons. A successful theory would help to show us a route through the thicket of views known as “methodological individualism”. It would have a bearing on the plausibility of legal positivism. It would be relevant to the question whether collectives are capable of acting. The debate about the ontology of collectives is therefore important for such fields as the theory of action, social and political philosophy, the philosophy (...) of law and the philosophy of social science. I hope to contribute to the debate by proposing an account of collectives, and by showing its theoretical soundness and utility. In its essentials, my proposal is that collectives are “mereological sums” of “stages” of persons linked by a “unity relation”. The influence on this account of some theories of personal identity will perhaps be obvious. But the motivation is different, for it lies at least as much in the ability of the theory to help us deal with the issues already mentioned as in problems concerning the identity of collectives over time. I acknowledge that my proposal is not commonsensical; however, I believe that no account could be both commonsensical and adequate. I will begin by introducing some constraints on a theory of collectives. (shrink)

There is a gap between, on the one hand, the tragic character of human action and, on the other hand, our moral and legal conceptions of responsibility that focus on individual agency and absolute guilt. Drawing on Kierkegaard’s understanding of tragic action and engaging with contemporary discourse on moral luck, poetic justice, and relational responsibility, this paper argues for a reform of our legal practices based on a less ‘harsh’ (Kierkegaard) conception of moral and legal responsibility and directed more at (...) empathic understanding based on the emotional and imaginative appreciation of personal narratives. This may help our societies and communities to better cope with unacceptable deeds by individuals who are neither criminals nor patients, to make room for praise as well as blame and punishment, and to set up practices and institutions that do not rely on a conception of responsibility that is hard to bear for all of us.

The aim of this paper is to provide a philosophic answer to a question, which is not at all rhetoric, as it may seem. The author, in fact, wonders whether identity has to be framed, as usual, as an absolute value, i.e., as an “all-or nothing” question. The conclusion of this inquiry is clearly a negative one: Identity, on the contrary, has to be seen as a value which is highly complex, fuzzy, and allowing for degrees, nuances, and trade-offs. In (...) modern societies there must be an interplay between identity and difference which is capable of ensuring institutional fairness and ongoing multicultural dialogue. (shrink)

Abstract.Legal philosophy must consider the way in which laws function as reasons for action. “Simple positivism” considers laws as merely reasons in the balance of reasons. Joseph Raz, as a representative of “sophisticated positivism,” argues that laws are exclusionary reasons for action, not merely reasons in the balance of reasons. This paper discusses Raz's arguments for his view. The Functional Argument provides no more reason for positivism than against it. The Phenomenological Argument is best supported by an account of how (...) character traits function in explaining behaviour. But then the distinction between exclusionary reasons and expressive reasons is obliterated. Legal positivism cannot absorb laws as expressive reasons for action. Raz's positivism implies the correctness of an anti‐positivistic legal theory. (shrink)

The separability thesis claims that the concept of law can be explicated independently of morality, the normativity thesis, that it can be explicated independently of fact. Continental normativism, prominent above all in the work of Hans Kelsen, may be characterized in terms of the coupling of these theses. Like Kelsen, H. L. A. Hart is a proponent of the separability thesis. And–a leitmotiv–both theorists reject reductive legal positivism. They do not, however, reject it for the same reasons. Kelsen's reason, in (...) a word, is the normativity thesis. Hart, however, grounds his theory in social fact. In place of the reductive thesis of the legal positivist tradition, and in sharp contrast to Kelsen's normativity thesis, Hart defends a non‐reductive version of what the author terms the facticity thesis.

This essay argues for a conception of law as a normative practice, a conception which departs from traditional, particularly positivist, conceptions. It is argued that Dyzenhaus's book (Dyzenhaus 1991), with its fascinating case study of unjust judicial decisions in South Africa, makes a compelling argument for such a conception. However, the essay takes issue with Dyzenhaus for romanticising the liberal tradition, and inflating the power of law and legal theory. Nonetheless, the essay agrees that positivist accounts tend to downplay the (...) emancipatory promise of law, and ends with some remarks about promise. (shrink)

In this paper, the author responds to the claim that his critique of legal positivism, based on an account of adjudication in South Ahica, misses its target because it ignores, first, the positivist thesis of judicial discretion and, secondly, the fact that positivism offers no account of judicial obligation. He argues that these theses expose a tension in positivism between its commitments to liberal individualism and to the supremacy of positive law, a tension which can be resolved only by situating (...) positivism in its true context, the Hobbesian argument for the legitimacy of law. Following Dworkin, he advocates the practice‐oriented common law tradition, one that makes the legitimacy of law a matter of standards already implicit in law which are best revealed in adjudication.

The author discusses a number of issues in the theory of legal sources. The first topic is whether sources should be conceived of as acts or texts. The alternatives are connected with two competing theories of legal interpretation (viz., the cognitive theory and the sceptical theory), which entail different concepts of legal rules and law‐making. The second topic is whether a “formal” or a “material” criterion of recognition of sources should be preferred. The third section is devoted to the analysis (...) of rules of change. Four theories of rules of change are discussed, and five kinds of such rules are distinguished. The fourth section concerns judicial law‐making, with special reference to the creation of new legal rules by constitutional courts. (shrink)
