The purpose of the work is to examine the existing theoretical structures on the issue of determining the scene of an extremist crime using the information and telecommunications networks and, accordingly, the territorial jurisdiction of criminal cases, as well as to studythe practical side of the issue. Methods: the methodological framework for this research is a set of methods of scientific knowledge: dialectical, system, analysis, logical. Results: the author’s well-founded position is based on the current legislation, explanations of the Plenum of the Supreme Court of the Russian Federation, current judicial practice, the position of scientists - processualists on determining the time and place of the crime in the global information network and the dependence of the criminal investigation on these factors. Conclusions: the study determined that extremist crimes committed using the information and telecommunications networks, including the Internet, are characterized by extraterritoriality and may be subject to the jurisdiction of several states.
