The Willem C. Vis International Commercial Arbitration Moot is one of the most prestigious international moot court competitions for law students. Taking place annually in Vienna since 1994, it gathers up more 2000 students, practitioners and academics with an objective of fostering the study of the international commercial law and arbitration.

For the 11th consecutive time, the University of Lausanne is presenting a team to the Vis Moot and will be represented this year by :

 Carole Moudon, Marta Zamorska, Patrick Pithon and Jonas Zaugg.

This year Jonathan Bornoz wil coach under the supervision of Professor Andrea Bonomi.

The team benefits as well from the support and guidance of

Sofia Drug-Villaverde, Sergii Drug, Friederike Brégeault and Professor Eva Lein.


The Problem of the XXV Moot concerns the complex issue of the challenge of an arbitrator under the UNCITRAL arbitration rules as well as the peculiarity of such challenge in an ad-hoc arbitration. The problem also deals with the problematic of the inclusion of standard terms to the contract under the CISG and the issue of non-conformity of the goods in relation with the Corporate Social Responsibility Code of one of the party.

The Moot problem can be accessed on the Moot website
