Vienna Convention on the Law of Treaties
The ILC has since held annual sessions at the U.N. Office at Geneva to discuss and debate various topics in international law and develop international legal principles accordingly. It is responsible for several foundational developments in international law, including the Vienna Convention on the Law of Treaties, which establishes a framework for forming and interpreting treaties, and the International Criminal Court, the first permanent tribunal tasked with adjudicating offenses such as genocide and crimes against humanity.
