This Guidebook is a tool for public officials—election management bodies, law enforcement, or other institutions—who are responsible for carrying out election investigations or fact-finding processes in politically sensitive and time restrained electoral environments. This Guidebook seeks to provide comparative examples of how different countries approach election investigations, and to set out a general framework and guidelines for the investigative process. The content and design are informed by more than three decades of global experience by IFES with election dispute resolution (EDR) processes.
