Jus Cogens: A Conversation with UN ILC Special Rapporteur Dire Tladi


Although the existence of jus cogens as a normative category in international law is no longer contested, the exact content of jus cogens, the means of identifying jus cogens rules, and the impact of jus cogens on general international law remains the subject of intense discussion, if not outright controversy, among states and within the international legal community. In this webinar, which is co-sponsored by the Africa Interest Group and the International Legal Theory Interest Group, Professor Dire Tladi, the UN ILC Special Rapporteur on jus cogens, will share his views on this topic, discuss the progress achieved by the ILC, and outline his views for the future of this project at the ILC. Three outstanding panelists will also participate as discussants. They will engage with Professor Tladi and share their comments and thoughts on the work of the ILC on jus cogens and reflect on the role and impact of jus cogens in international law
