The most influential theory of law in current analytic legal philosophy is legal positivism, which generally understands law to be a kind of institution. The most influential theory of institutions in current analytic social philosophy is that of John Searle. One would hope that the two theories are compatible, and in many ways they certainly are. But one incompatibility that still needs ironing out involves the relation of the social rule that undergirds the validity of any legal system (H.L.A. Hart's (...) rule of recognition) to Searle's notion of codification: the idea that institutions need official declarations of their constitutive rules in order to enjoy the full benefits of institutions. The incompatibility arises from the fact that, in order to do its institutional work, the basic validity rule must be codified in Searle's sense—yet, given the particular role it has in legal positivism, it may be impossible to codify in the Searlean sense. In this paper I develop the incompatibility in detail, consider and reject consigning the basic validity rule to Searle's “Background” capacities that support institutional facts, and conclude that the best route to eliminating it while doing a minimum of damage to the two theories is to make a slight emendation to Searle's theory of institutions.

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.

How to distinguish law from non-legal but systematic and rule-guided practices of legal officials? This issue features prominently in the debate on ‘positive originalism’ in US constitutional law, and in similar fundamental controversies in other legal orders. I take it as a question about content and constitution of ultimate rules of recognition. Legal philosophers have been too quick in dealing with this problem. I argue that there is more space to claim that non-officials have a constitutive relationship with the content (...) of the law, thus potentially providing a standard to distinguish legal and non-legal practices of officials. However, to the extent officials play a constitutive role in the law, what matters is their genuine acceptance of ultimate rules of recognition. To show this, I develop the concept of acceptance of a social rule by specifying the requirement of genuineness of acceptance and the role of mental dispositions associated with acceptance. (shrink)
