On May 29, 2025, the American Branch of the International Law Association convened the first session of their Study Group on Crimes Against Humanity. The Study Group brings together eminent international law experts and practitioners, with Professor Leila Nadya Sadat, Director of the Crimes Against Humanity Initiative, as their Chair.

The Study Group is charged with reviewing the International Law Commission’s 2019 Draft Articles on the Prevention and Punishment of Crimes Against Humanity and making recommendations as necessary to strengthen the draft treaty’s language and substance. Their insights will support State delegations as they develop their positions and prepare for formal treaty negotiations.

The Study Group may also propose draft provisions that it believes could advance the progressive development of international law.
