Non-Disclosure of Pre-Trial Investigation Data: Legal Framework and Practical Implementation
https://doi.org/10.17803/1729-5920.2026.236.7.040-051
Abstract
The paper highlights that criminal procedure law permits the application of the institution of nondisclosure of preliminary investigation data at any pretrial stage of criminal proceedings. It concludes that the category of «preliminary investigation» should be interpreted broadly — as the activity of authorized actors aimed at exposing offenders and fulfilling the purposes of criminal proceedings — which makes it possible to hold persons liable for disclosing preliminary investigation data (Art. 310 of the Criminal Code of the Russian Federation) at the stage of initiating a criminal case. The study notes that the implementation of this institution is directed not only toward safeguarding the rights and freedoms of participants in criminal proceedings but also toward ensuring the interests of justice from the moment a crime report is received. It argues for the unity of the principles of criminal proceedings and the general conditions of preliminary investigation for all participants involved in the proceedings, emphasizing that the institution under study may be applied to suspects and accused persons without violating their right to defense. The author points out that the procedural status of a suspect or an accused person does not include an obligation to sign an undertaking not to disclose preliminary investigation data, but that this does not prohibit preliminary investigation authorities from obtaining such an undertaking. Recommendations are offered to persons conducting preliminary investigations regarding the selection of preventive measures involving restrictions on the liberty of suspects and accused persons when they refuse to provide the undertaking at issue. The paper substantiates that the content of an undertaking not to disclose preliminary investigation data depends on the circumstances of the particular criminal case, thereby underscoring the absence of any need to establish by statute an imperative list of information not subject to disclosure.
