XXVI Vis Moot - 2018/2019

                     26th Willem C. Vis International Commercial Arbitration Moot

                                               Excellents résultats de l’équipe lausannoise

Le Willem C. Vis Moot (« Vis Moot ») est la plus grande compétition étudiante dans le domaine du droit du commerce international et du droit de l’arbitrage, réunissant environ 370 universités du monde entier. Créé en 1993 dans le but de promouvoir l’étude de l’arbitrage commercial international, le Vis Moot est organisé autour d’un procès fictif prenant la forme d’une procédure arbitrale, opposant deux sociétés commerciales, ayant conclu un contrat international régi par la Convention de Vienne sur la Vente Internationale de Marchandises (« CVIM ») et soumis à résolution arbitrale.

                                           Cette année, l’équipe de l’UNIL était composée de 

              Johana Abbondanza, Nerea Garcia Vazquez, Narges Keshavarz Bahadori et Mattia Deon.

Pour sa 12ème participation au Moot, l’équipe représentant l’UNIL a été brillante, puisqu’elle a réalisé la meilleure performance suisse à l’écrit au Vis Moot de cette année, en obtenant les classements suivants :

  • Honorable Mention pour son mémoire défendant la position du défendeur, seule université suisse à l’obtenir (Honorable for the Werner Melis Award, Best Memorandum for Respondent, décernée à 30 universités sur 372)
  • Honorable Mention pour son mémoire défendant la position du demandeur (Honorable mention for the Pieter Sanders Award, Best Memorandum for Claimant, décernée à 34 universités sur 372)

L’équipe a été coachée par Jonas Zaugg, avec le soutien de Timo Cöster, et sous la supervision du Professeur Andrea Bonomi. Elle a également bénéficié du généreux soutien des études Homburger, Schellenberg Wittmer et Walder Wyss.
