The School of International Arbitration, Centre for Commercial Law Studies, Queen Mary University of London and Calunius Capital are pleased to announce the School of International Arbitration's forthcoming inaugural seminar on Group Actions in Arbitration. Leading experts from academic, practice and arbitration institutions and international organisation will discuss different approaches in common and civil law systems, the emergence of group actions in commercial arbitration and the experience with similar cases in investment arbitration. Insights will also be offered as to whether some regulation may be necessary in the future.
