The Format
Each year, a distinguished scholar or practitioner is invited to engage intensively with a group of 10–15 advanced students, doctoral candidates, and postdoctoral researchers on a key topic in international dispute settlement. The Masterclass consists of two sessions, a morning and an afternoon session, and will comprise a duration of approximately six hours in total.
The Masterclass 2027
The topic of the Inaugural Masterclass is “Evidence in International Adjudication”. The preparation and presentation of evidence plays as crucial a role in international adjudication as it does in domestic proceedings. Cases are at least as likely to be won or lost on the facts as they are on the law. Yet, in contrast to the position in national legal systems, the legal rules and principles applicable to evidence before international tribunals are often vague and uncertain. They leave much to the initiative of the parties and the discretion of the tribunal. International adjudication brings together parties, counsel, and tribunal members from different legal traditions, with different approaches to evidence gathering and presentation. How should this system be made to work in order to ensure that each party’s case is presented most effectively and the tribunal is placed in the best position to decide the dispute?
