Digital open-source evidence has become ubiquitous in the context of modern conflicts, leading to an evolution in investigative practices within the context of mass atrocity crimes and international criminal law. Despite its extensive promulgation, international criminal tribunals have had few opportunities to address the admissibility of user-generated open-source evidence. Through semi-structured interviews with experts and analyses of primary and secondary sources, this article examines the current standards and practices governing the use of user-generated open-source evidence. Current practices illuminate a number of gaps in the realm of digital open-source evidence in international criminal law. This article posits the establishment of a standing international, investigative mechanism as a solution to a need for increased standardization and co-ordination within the realm of user-generated open-source evidence. By standardizing the collection and use of such evidence, investigative bodies will be prepared to more effectively serve the international justice community.
