Dworkin's theoretical disagreement argument, developed in Law's Empire, is presented in that work as the motivator for his interpretive account of law. Like Dworkin's earlier arguments critical of legal positivism, the argument from theoretical disagreement has generated a lively exchange with legal positivists. It has motivated three of them to develop innovative positivist positions. In its original guise, the argument from theoretical disagreement is presented as ‘the semantic sting argument’. However, the argument from theoretical disagreement has more than one version. (...) This article briefly discusses two versions and the leading replies to them, then focuses on the most influential version, directed at Hartian positivism. The article surveys the leading positivist rejoinders to the recast version, indicating key Dworkinian replies or assessing the strength of these rejoinders, and concludes with a rejoinder of its own, making a new case that the argument from theoretical disagreement isn't fatal for Hartian legal positivism.

Scott Shapiro’s Legality argues the positivist Planning Theory of law meets the anti-positivist challenge posed by the argument from theoretical disagreements about law in Ronald Dworkin’s Law’s Empire. Legality equates theoretical disagreements with what Shapiro calls meta-interpretive disagreements, and then offers a legal theory of meta-interpretation that purportedly accounts for the existence of meta-interpretive disagreements by showing how it is rational or intelligible for legal actors to have such disagreements. This paper argues Legality misconstrues Law’s Empire. The true challenge of (...) ATD was to provide a theory of law that would vindicate the judgment that law is discovered in cases of theoretical disagreements, rather than made. Legality sees the challenge of Law’s Empire to be to show how it is rational or intelligible for legal actors to have theoretical disagreements, which is different from showing how there really is pre-existing law to be found in cases of theoretical disagreements. So the challenge Legality addresses is circumscribed. But Legality does not even succeed at addressing its own more circumscribed challenge, because, under the Planning Theory of meta-interpretation, legal actors are mistaken to think they are finding law in cases of theoretical disagreements.

Comment on Joseph Raz, From Normativity to Responsibility.

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.
