This course presents an introduction to international commercial arbitration and briefly addresses investor-state arbitration. It examines the nature of arbitration, the procedures used in international arbitration (both institutional and ad hoc) and the enforcement of and setting aside of arbitral awards. The course will also cover drafting arbitration agreements, the law applicable to arbitrations (including the New York Convention, the ICSID Convention and various institutional rules), challenges to arbitration, multi-party arbitrations, jurisdiction, preliminary or interim measures and selection of the arbitral tribunal. The course also provides an introduction to arbitration between investors and states. Grades will be based primarily upon short papers addressing current issues in international arbitration.
