Presented on 23 April 2026 in Washington, DC, the Manley O. Hudson Medal is among the most prestigious distinctions in the field of international law. It recognizes individuals whose scholarship and professional achievements have made an exceptional and lasting contribution to the discipline. The ASIL emphasized Professor Boisson de Chazournes' profound influence on generations of students and practitioners worldwide-an impact reflected in her leadership at the CIDS and her continued teaching at the MIDS.
Professor Boisson de Chazournes has acted as counsel, arbitrator, and judge before leading international courts and arbitral institutions, including ICSID, the ICC, the Permanent Court of Arbitration, the Arbitration Institute of the Stockholm Chamber of Commerce, and the Court of Arbitration for Sport. She serves as a judge at the Administrative Tribunal of the Bank for International Settlements and has chaired WTO arbitration panels on pre‑shipment inspections. Her advocacy before the International Court of Justice, the International Tribunal for the Law of the Sea, and other dispute settlement fora further illustrates the breadth of her contributions.

The CIDS extends its warmest congratulations to Professor Boisson de Chazournes on this distinguished recognition, which honours her remarkable career and enduring contribution to the development of international law.
