The Urgency of Witness and Victim Protection in Transnational Crimes: A Comparative Study of International Law

The growing complexity of transnational crimes such as human trafficking, narcotics trafficking, cyber-enabled offenses, and cross-border corruption has heightened the urgency of effective witness and victim protection mechanisms. Witnesses and victims face substantial risks of intimidation and retaliation, which can undermine investigations and prosecutions. This study employs a normative juridical method combined with a comparative legal approach to examine the international legal framework particularly the UN Convention against Transnational Organized Crime (UNTOC) and the Trafficking in Persons Protocol and its implementation across several jurisdictions. Data were collected through library research, including international instruments, national regulations, and recent academic literature, and analysed qualitatively using statute and conceptual approaches. The findings indicate a persistent gap between international standards and domes c implementation. Substantive challenges arise from fragmented legal norms, divergent definitions of transnational crimes and witness/victim status, and the absence of a unified legal basis for cross-border relocation. Implementation challenges include limitations in resources, weak inter-agency coordination, the lack of standardized cross-jurisdictional procedures, and increasing difficulties related to digital identity protection and electronic evidence. Comparative analysis shows significant variation in protection models, ranging from comprehensive systems such as WITSEC in the United States, strong oversight structures in Canada, to fragmented arrangements in Australia. In Indonesia, the Witness and Victim Protec on Agency (LPSK) continues to face constraints in capacity and international cooperation. This study recommends harmonizing international and domes c norms, strengthening mutual legal assistance mechanisms, establishing fast track cross-border cooperation systems, enhancing the capacity and resources of protection agencies, adopting a victim-centred approach, and developing shared standards for digital evidence management and secure technological tools for witness examination. Implementing these recommendations is essential to improving witness and victim protection and reinforcing the effectiveness of transnational crime enforcement.
