Extract

Hidemi Suganami's thoughtful criticisms of my recent article in the Review1 throw valuable light on some of the key elements of the argument which I tried to outline there. None the less, those criticisms do not seem to undermine my central argument, which is that there is a difference between the conception of customary international law as a set of laws which in principle bind all states and the conception of customary international law as a set of obligations which in principle bind only those states which have consented to be bound by them. By ‘law’ here, I mean a rule which purports to apply to all entities which fall within the open-ended set (i.e., ‘states’) which constitutes its sphere of application rationae personae. An ‘obligation’, on the other hand, claims no such general applicability, but—in the case of consensual obligations, with which we are here concerned—is only binding upon the closed set of states which have consented to be bound by it. There is, in my view, no good reason why the orthodox conception of customary international law as a set of laws should be preferred to the conception of customary international law as a set of obligations.
