There are limits to what can be achieved using the means and medium of international law. This article explores those limits by providing an innovative theory of the nature of international law and how we should understand its limits in terms of value theory. A "four functions" theory is proposed, and these functions are used to interpret areas of international law in terms of their distinctive and valuable contribution to a specific area of human relations. On the basis of this analysis of international law and international legal interpretation, the paper argues that the cosmopolitan aims of a number of moral cosmopolitan scholars fail to taken into account the value limits of international law. This is presented as a value problem, not a problem of feasibility or practicality.

This chapter considers the key values underlying and explaining important features of international law as a system of law. It uses that value analysis as a way of interpreting international law and of asking whether, within those values, international law can be made to serve certain 'global cosmopolitan' re-distributive aims. The chapter argues that the constraints of international law mean that it is not an appropriate medium for global re-distributive goals commonly associated with theories of societal justice. Because those features and constraints are based in values that international law distinctly serves, those constraints cannot simply be ignored, overridden, or changed judicially.
