The International Law Commission (ILC) is a subsidiary organ of the UN General Assembly. It was established in 1947 to undertake the mandate of the Assembly, under article 13 (1) (a) of the Charter, to “initiate studies and make recommendations for the purpose of… encouraging the progressive development of international law and its codification.”
Prof. Dire Tladi was first elected to the ILC in November 2011, and re-elected in 2016. In 2015 he was appointed to serve as its Special Rapporteur for the topic of jus cogens. Since then he has lead the Commission’s efforts to give content to jus cogens by identifying how rules and norms are elevated to that status and determining the impact of these norms.
In 2017 the Commission decided to change the title of the topic from “jus cogens” to “peremptory norms of general international law (jus cogens)”.
