The article sets out to explore the international legal dimension in Jürgen Habermas' latest publications on philosophy of law. It is our view that Habermas deals with the examination of just relations beyond the nation-state first and foremost from a legal perspective, and that the key to a Habermasian reading of international justice is not through an application of discourse-theoretical models of communicative or moral action as such, but primarily through proper legal institutionalisation of the rule of law. In asserting (...) this view, we will look closer at the Kantian influence in Habermas' legal construct at the international level, and show why this institutional approach is to be sharply distinguished from and preferred to any exclusively non-institutional approach to international justice.
