Abstract This research article aims to evaluate the effectiveness of Tanzania's witness protection framework in relation to international standards, identifying gaps and challenges that hinder the protection of witnesses in the criminal justice system. It seeks to propose actionable recommendations to enhance legal protections and operational practices. Utilizing a qualitative legal research methodology, this study employs both doctrinal and empirical approaches. The doctrinal method involves reviewing relevant legal documents, including statutes, case law, and international legal instruments. Empirical data are gathered from secondary sources such as books and journal articles. This comprehensive analysis helps assess the compliance of Tanzania’s witness protection measures with international norms. The findings reveal significant deficiencies in Tanzania’s witness protection system, including inadequate legal provisions, a pervasive culture of fear among potential witnesses, insufficient funding, and inconsistent implementation of protective measures. These challenges discourage witness cooperation and compromise the integrity of the judicial process. This research contributes to theory by integrating criminal justice and human rights frameworks, highlighting the necessity of viewing witness protection as both a procedural and fundamental human right. Practically, it emphasizes the adoption of international best practices, advocating for specialized training for law enforcement to enhance witness safety. Policy recommendations call for legislative reforms to establish a dedicated witness protection agency and improve public awareness about witness rights. By addressing these areas, the study aims to align Tanzania’s practices with global standards, thereby fostering a more effective and trustworthy criminal justice system.
