VenueBucerius Law School, Helmut Schmidt Auditorium, Jungiusstraße 6, 20355 Hamburg
Fees150 € (The Optional Conference Dinner has to be booked separately.)

In most international arbitrations experts play a crucial role for the outcome of the dispute. At the same time, there is little regulation as to their participation in the proceedings, the standards of independence required or possible challenges. Depending on their background parties and arbitrators often have different expectations as to the role of the experts, in particular when they are party appointed experts and not tribunal appointed experts.

The Center for International Dispute Resolution at Bucerius Law School, CAM-CCBC, HAC and Rechtsstandort Hamburg e.V. invite you to join the debate on use, obligations and challenges of experts in arbitration.
