Reflections on possible vectors of the institution of preliminary investigation suspension development

The decision to suspend the preliminary investigation is often the only way for the law-enforcement activity to ensure the rights and legitimate interests of persons interested in the outcome of a criminal case without attack on the reasonable duration of the investigation until the purpose of criminal proceedings is achieved. At the same time, the implementation of the institution often causes ambiguous reactions among the population and the control and supervisory state bodies. This is partly due to the need to introduce the systemic changes in the legal regulation of the institution of preliminary investigation suspension, taking into account the existing law enforcement practice and the results of scientific research. The author makes the attempts to identify possible ways of normative development of this institution.
