The Seminar closed its 52nd session on 22 July 2016.

UNOG organized the very first International Law Seminar (ILS) in 1965, in connection with the annual session of the International Law Commission (ILC), for a duration of three weeks.

The Seminar takes place on an annual basis and is designed for postgraduate students in international law, young scholars, government officials as well as young lawyers in the field of international law, to widen their knowledge of both the work of the International Law Commission and of the codification and progressive development of international law. It also provides an opportunity for lawyers coming from different legal systems and cultures to exchange views regarding items on the agenda of the Commission.

The International Law Seminar is not intended to be an introduction to international law. Applicants must prove a sound knowledge of international law, on the basis of either their postgraduate studies or significant professional experience in the field. Twenty five participants from various Member States of the United Nations participate in ILS. As well as attending the meetings of ILC, participants are expected to take an active part in the discussions which follow lectures given by members of the Commission, officials of the United Nations or specialized agencies in Geneva and other speakers invited for the occasion.
