Abstract

I argue that there are two conceptions of ‘comprehensiveness’: 1) Raz’s strong conception whereby comprehensiveness entails supremacy, and 2) a weak conception whereby comprehensiveness does not entail supremacy. The latter is sufficient to distinguish legal and non-legal authorities, and unlike Raz’s notion of comprehensiveness, allows one to account for both intra-state forms of legality (e.g., the federal-provincial relation in Canada) and supra-state forms of legality (e.g., the European Union). Moreover, although it is ideal for legal systems to claim supremacy, it is not necessary – it is possible for legal systems to recognize as valid the norms of other legal systems.
