Normative IR Theory and the Legalization of International Politics: The Dictates of Humanity and of the Public Conscience as a Vehicle for Global Justice

This paper explores the relationship between normative international political theory and the politics of international law. It begins by arguing that a gap between the normative (in moral terms) and the moral (in legal and social terms) still exists in the literature before going on to examine an approach to closing this gap. This approach, it is argued, is common to a plurality of theoretical approaches including liberal cosmopolitanism, social constructivism and forms of particularism. In exploring ‘institutional moral reasoning’ or ‘social moral epistemology’ the paper argues that respecting the institutional autonomy of the international legal order is a key component of the approach. In order to test the extent to which the various positions do respect the autonomy of the legal order the paper engages with an analysis of the extent to which human rights have become the key constitutive norm of global politics
