Abstract
This paper defends the pertinence of global justice in the contemporary world. It accepts, for the sake of argument, Nagel's view that matters of justice arise only when political authority is asserted or exercised and, connectedly, his rejection of the cosmopolitan thesis. However, it challenges his conclusion that considerations of justice do not apply beyond the state. It argues that on any plausible account of the relationship between authority and justice international institutions, such as the World Trade Organisation, are now authoritative in the right way to justify their evaluation from the point of view of justice
