The Philip C. Jessup International Law Moot Court is the oldest and most prestigious international law competition in the world. This year, the University of Vienna was represented by Brian McMahon, Antonia Pitzl, Ilina Apostolovski and Katharina Tuider, who drafted two briefs for the applicant and respondent side from October to January and prepared intensively for the oral phase since January.

Out of a total of over 800 participating teams, the University of Vienna was one of 152 to reach the International Rounds in Washington D.C. There, the Viennese team passed the preliminary rounds and was only one of three teams from the EU to reach the round of 32. Only in the Round of 16 Vienna narrowly lost in a split bench decision against the experienced team from the National University of Kyiv-Mohyla Academy, which would go on to reach the final and had already won the Telders International Law Moot Court in 2024. Overall, the Viennese team placed among the top 4% worldwide and reached the coveted Advanced Rounds for the 4th time in a row.

This year's Viennese team also excelled at the regional level. In March, it achieved 2nd place in the European Friendly Rounds after reaching the final. In addition, all team members placed among the top 6 in the individual ranking of speakers, with Ilina Apostolovski even achieving 1st place.

The Jessup Moot Court simulates proceedings before the International Court of Justice (ICJ) based on a fictitious dispute between two states. The students represent the applicant and respondent sides. This year's case concerned the interpretation of a compromissory clause in the founding treaty of a regional international organization; the legal identification of a legitimate head of state when several persons claim this role; the immunity of government representatives accused of enforced disappearances; and the legal consequences of the receding coastline for maritime claims of coastal states. This year's final judges were former ICJ President Joan Donoghue from the US and the two sitting ICJ judges Juan Manuel Gomez Robledo from Mexico and Georg Nolte from the Federal Republic of Germany.

Singapore's Management University won the final round and claimed the championship by beating the National University of Kyiv-Mohyla Academy from Ukraine.

This year’s team was supervised by Fritz Kainz and Paulina Rundel. The team was supported by the University of Vienna, Freshfields, Schönherr Rechtsanwälte, Zeiler Rechtsanwälte and Annacker International Disputes.
