Expert witnesses can play a vital, even determinative, role in a case. An expert witness can explain and assess complex scientific or technical evidence or provide significant contextual analysis that can be central to the successful litigation of a case. EHRAC has instructed experts in a number of its cases across the region, including in Dzidzava v Russia (concerning the mass expulsion of Georgian nationals from Russia between September 2006 and January 2007).
This Guide provides assistance to lawyers as to why, when and how to instruct an expert in international litigation.
The English and Russian versions of this guide were updated in August 2026.
