University of Lausanne continued its participation in the world famous Willem C. Vis International Commercial Arbitration Moot, this time in the XXIII instalment of the Moot and for the 9th consecutive time altogether. This year’s Moot included 312 participating universities from 67 countries from all over the world.

The Team of the University of Lausanne was represented by Theresia Kloetzli, Romain Venard, Tifaine Hostettler and Mehdi Hajilou.

The Team has been coached by Sofia Drug-Villaverde and Sergii Drug under the supervision of Professor Andrea Bonomi.

The participation of the University of Lausanne has been a great success, marked with an award of an honourable mention in the competition for Pieter Sanders Award for the Best Memorandum supporting the position of Claimant (for the 4th consecutive time), as well as an honourable mention in the competition for the Werner Mellis Award for the Best Memorandum supporting the position of Respondent (for the 2nd time).

With this achievement, University of Lausanne becomes one of the sixteen universities in the world that received mentions for both memoranda in the XXIII Willem C. Vis International Commercial Arbitration Moot.

On top of that, with its 4th consecutive honourable mention for the Memorandum for Claimant, the University of Lausanne has become one of the two universities in the world to do so in the past four editions of the Moot, alongside with the University of Freiburg, Germany.

The Problem of the XXIII Moot concerned the complex issue of the recoverability of the legal costs as damages as well as the disgorgement of profits under the CISG. The Problem also dealt with the issue of the document production and its scope in international commercial arbitration. The Moot Problem can be accessed on the Moot website.




Professor Andrea Bonomi has been in charge of the Vis Moot program at the University of Lausanne since its team participated in the Moot for the first time in 2008.  For more details on Professor Bonomi’s extensive experience and publications, please visit UNIL’s website.
