The essay discusses the import of the separability thesis both for legal positivism and for contemporary legal practice. First, the place of the separability thesis in legal positivism will be explored, distinguishing between “standard positivism” and “post‐Hartian positivism.” Then I will consider various kinds of relations between law and morality that are worthy of jurisprudential interest, and explore, from a positivist point of view, what kind of relations between law and morality must be rejected, what kind of such relations should (...) be taken into account, and what kind of such relations are indeed of no import at all. The upshot of this analysis consists in highlighting the distinction between two different dimensions of legal validity (formal validity and material validity respectively), and in pointing out that the positivist separability thesis can apply to formal validity only. On the other hand, when the ascertainment of material validity is at stake, some form of moral reasoning may well be involved (here and now, it is necessarily involved). The essay concludes with some brief remarks on the persisting importance of the positivist jurisprudential project. (shrink)

This article argues that the courts, not the Home Secretary, should be empowered to issue Terrorism Prevention and Investigation Measures. It explains that at the heart of the debate are three questions: whether measures like TPIMs should be viewed primarily from the perspective of security or liberty; how we should conceive the executive and the courts; and the empirical question of how these two arms of government answer these questions. The non-mechanistic nature of legal reasoning means that legal reasons may (...) be constructed to fit one’s normative viewpoint on each of the first two questions. Importantly, however, the case law on judicial scrutiny of control orders consistently demonstrates that the courts themselves regard TPIMs as being primarily a restriction on liberty, which require a fair hearing before an independent court. Whilst this does provide some protection of individual rights, the nature of law as an unfinished practice means that for stable protection of individual rights judicial independence must be promoted and nurtured in both the legal and political realms. The failure of the Terrorism Prevention and Investigation Measures Act 2011 to vest the power to issue TPIMs in the courts thus represents a missed opportunity to secure political endorsement of enhanced legal protection of individual liberty in cases involving national security.

Abstract. The purpose of this paper is to address some of the main issues of contemporary jurisprudential methodology by considering the contribution of Jules Coleman to this subject. After a description of Coleman's methodological approach and a clarification of its philosophical background, the paper focuses on some related problems, such as the relation between linguistic meaning and conceptual content, the nature of legal concepts, the different aspects of the normativity of content, and the revisability of conceptual truths.
