Abstract.Although the Hart/Dworkin debate has as much to do with Dworkin's affirmative theory of judicial discretion as with Hart's more comprehensive theory of law, the starting point was of course Dworkin's attempt to demolish the “model of rules,” Hart's alleged analysis of legal systems as collections of conclusive reasons for specified legal consequences. The continuing relevance of this attack for the prospects for any theory of law is the subject of the present essay.

In this essay, I characterize the original intervention that became Inclusive Legal Positivism, defend it against a range of powerful objections, explain its contribution to jurisprudence, and display its limitations and its modest jurisprudential significance. I also show how in its original formulations ILP depends on three notions that are either mistaken or inessential to law: the separability thesis, the rule of recognition, and the idea of criteria of legality. The first is false and is in event inessential to legal (...) positivism. The second is inessential to legal positivism. The third is likely inessential to law. I then characterize the central claim of ILP in a way that relies on none of these: ILP is the claim that necessarily social facts determine the determinants of legal content. I show that ILP so conceived leaves the central debates in law largely untouched. I suggest how the most fundamental of these—the question of the normativity of law—at least can be usefully addressed. The essay closes by suggesting that even though one can distinguish the social from the normative dimensions of law, a theory of the nature of law is necessarily an account of the relationship between the two: It is a theory either of the difference that certain distinctive social facts make in normative space, or it is an account of the distinctive normative difference that law makes, and the social and other facts that are necessary to explain that difference. One can distinguish between but one cannot separate the social from the normative aspects of legality. (shrink)

This article connects the insights of post-realist scholarship about radical indeterminacy and its consequences for the legitimacy of adjudication to the current legitimacy crisis of the international investment regime. In the past few years, numerous studies have exposed serious shortcomings in investment law and arbitration including procedural problems and the substantive asymmetry of the rights protected. These criticisms have prompted a broad consensus in favor of amending the international investment regime and multiple reform proposals have appeared that appeal to the (...) rule of law ideal as an instrument for increasing the acceptability of the international investment system. This article argues that the reliance of such proposals on jurisprudential approaches that fail to adequately accommodate the post-realist indeterminacy critique and take seriously the role of ideology in adjudication renders reform efforts unable to solve the legitimacy problems of the investment regime. The conclusions suggest the need to abandon implausible claims to depoliticization and face the methodological challenges posed by the promise of ideologically balanced assessments advanced by some rule of law theorists. The article finally points at the urgency to reform traditional approaches to doctrinal work in order to increase awareness of critical challenges and open up doctrinal methods to alternative methodological avenues.
