This study examines the protection of suspects’ rights during the investigation process, which continues to reveal a gap between legal norms and practice. The objective is to analyze the implementation of the principle of due process of law in ensuring the protection of suspects’ rights at the investigation stage in Indonesia. A normative legal research method is employed using statutory and conceptual approaches with qualitative analysis. The findings indicate that although protection has been established through the Criminal Procedure Code and constitutional guarantees, its implementation remains influenced by an efficiency-oriented approach, weak oversight, and limited access to legal assistance. These conditions contribute to procedural violations such as coercive interrogation and wrongful suspect designation. Strengthening the principle of due process of law through criminal procedure reform, improved institutional accountability, and more active oversight mechanisms is therefore essential to achieve a fair criminal justice system that respects human rights.
