Use of expert witnesses in international arbitration: Experiences and preferences

Peter Rankin and Kristen Backor share results from their recent survey on the use of expert witnesses in international arbitration in Corporate Disputes. Expert witnesses are used in a variety of contexts and are selected on the basis of factors that are indicative of their degree of expertise. Good experts are those who are well prepared, work collaboratively with counsel, and are capable of expressing their opinions in a compelling manner. Practicioners recognize that they share the responsibility in ensuring that effective expert testimony is delivered by narrowing the issues and clarifying the expert’s mandate.
