The third biennial Conference of the European Society of International Law will be held in Heidelberg on 4-6 September 2008. This time the conference will be organized in association with the Max Planck Institute for Comparative Public Law and International Law. The organizers have chosen “International Law in a Heterogeneous World” as the main topic of the event. A preliminary programme can be found here. There has also been issued a call for papers. The topics that should be dealt with cover some of the more interesting areas of public international law, such as multiplicity of law-making processes, international law and the millennium development goals, legitimacy of international law and social justice.
