Use of digital technologies to optimize investigative actions at the pre-trial stage of criminal proceedings

Abstract

The relevance of the study was determined by the need for regulatory and legal incorporation of digital technologies at the pre-trial stage of criminal proceedingsThe aim of the study is to substantiate the indicator-based and model-based verification of digital technologies relevant to procedural integration at the pre-trial stage of criminal proceedings, taking into account regulatory traceability, evidentiary relevance, and legal incorporation. Research methods: legal analysis of norms and regulations, topological classification of digital technologies, formalization of the optimal case, indicator-based and model-based verification, legal modelling. The study carried out indicator-based and legal stratification of digital technologies at the pre-trial stage of criminal proceedings. It was established that Digital Forensics, AI, Biometrics, e-Evidence Exchange and Video Conferencing demonstrate the highest institutionalization, regulatory incorporation and evidentiary validity. Indicator-based modelling (∆TPI, DEQ, PII, EII, UAE, DJC) confirmed their legal compliance and procedural efficiency. The highest level of regulatory integration (4 out of 5 categories) was established for Digital Forensics, Biometrics, e-Evidence Exchange, and Video Conferencing technologies. Instead, Blockchain and Digital Twin/3D were identified as auxiliary, as they require additional legal explicability and ethical unification. Empirical analysis of the functional adaptability of technologies in a real investigative process is of particular importance.
