On March 12, 2025, the FGV Jean Monnet Centre of Excellence, co-funded by the European Union under the Erasmus+ programme, in partnership with the FGV Centre for Global Law, was honored to welcome Professor Brian McGarry, Assistant Professor of Public International Law at the Grotius Centre for International Legal Studies, Leiden University.

Professor McGarry's class was divided into two parts. In the first, he presented the controversies surrounding third-party intervention in contentious cases at the International Court of Justice (ICJ), highlighting the differences between Articles 62 and 63 of the Court’s Statute and the diverse perspectives associated with their application.

The second part of Professor McGarry's lecture addressed the practical application of interventions in the cases of The Gambia v. Myanmar, Ukraine v. Russia, and South Africa v. Israel. The discussion emphasized the challenges arising from the use of intervention articles and the lack of a clear definition, in the ICJ's case law, of the criteria for their application, specially regarding intervention as a party.

We sincerely thank Professor Brian McGarry for an engaging and enriching session on this fundamental topic.
