International-Legal Regulatory Issues of the Activities of Joint Criminal Investigation Groups

Abstract

This comprehensive study examines the international legal framework governing Joint Criminal Investigation Teams (JITs) and their operational challenges in combating transnational crime. The research analyzes the regulatory mechanisms, jurisdictional issues, and practical implementation of JITs across different legal systems. Through systematic analysis of current legislation, case studies, and scholarly literature, this article identifies key challenges in data protection, evidence admissibility, and cross-jurisdictional cooperation. The study highlights the critical role of international organizations like Europol and Eurojust in facilitating JIT operations while addressing emerging challenges in digital evidence collection and cybercrime investigations. Furthermore, it explores the financial aspects, human rights considerations, and future developments necessary for enhancing JIT effectiveness. The findings suggest that while JITs have proven to be valuable tools in international law enforcement, their success depends on continued legislative harmonization, technological integration, and strengthened international cooperation mechanisms. This research contributes to the ongoing discourse on improving the regulatory framework and operational efficiency of JITs in the context of evolving transnational criminal threats.
