The article deals with legislative bases and organizational problems of introducing criminal proceedings in electronic format in Kazakhstan. Fixing the possibility of criminal proceedings in the electronic format in a criminal procedure on the basis of a reasoned decision will, in the view of the authors ofthe bill, will allow to shorten the terms of the preliminary investigation and improve the quality of the criminal process. As the experience of the states using the system of electronic cases in the criminal process (Saudi Arabia, Georgia, South Korea, Singapore) shows, this format also increases the level of responsibility of participants in criminal proceedings, makes the process itself more transparent, and excludes opportunities for falsifying evidence. To speed up the investigation, as well as to harmonize the procedural documents with the CPC norms, it is necessary to develop electronic templates for the main procedural documents, to connect investigative units to the electronic resources of law enforcement bodies and the Prosecutor's Office in order to request documents and references online. The results of the pilot project are evaluated, the positive aspects of the electronic investigation and the difficulties encountered are demonstrated. The attention is focused on the information security of the new system.
