Biennial ILA Conferences

Every two years the International Law Association stages a major biennial conference, hosted by different national branches, that brings together the leading international lawyers, international law academics, and members of governments and international organizations from around the world. The last biennial conference was held in Athens, Greece, on June 25-28, 2024. The next biennial conference will be held in Vienna, Austria in 2026.

A major focus of each conference is on the work of the ILA’s committees and study groups, but plenary sessions and other panels address a wide range of leading international law issues. The 81st Biennial was hosted in Athens, Greece, the 80th Biennial was held in Lisbon, Portugal, the 79th was hosted online through Kyoto, Japan, and the 78th was hosted in Sydney, Australia.

The United States has hosted six of the ILA’s biennial conferences. Buffalo, New York was the location of the eighteenth conference in 1899, and the twenty-fourth was held in Portland, Maine in 1907. New York City was the site of the thirty-sixth (1930), the forty-eighth (1958), and the fifty-fifth (1972) ILA biennial conferences.

The sixth and most recent U.S. site to host an ILA biennial was the 76th ILA Biennial Conference which took place from April 7-12, 2014 at the Ronald Reagan Building and International Trade Center in Washington, D.C. The conference was held jointly with the Annual Meeting of the American Society of International Law. A joint Program Committee, made up of members of the ABILA, ILA, and ASIL and chaired by Oona Hathaway, Larry Johnson, and Fionnuala Ní Aolain, organized the joint program.
