<![CDATA[This study examines the comparative regulation, authority, and procedural framework of prosecution within the criminal justice systems of Indonesia and Thailand. The research focuses on the normative arrangements governing prosecution, the scope of authority exercised by public prosecutors, and the procedural differences in criminal proceedings that influence prosecutorial practices in both countries. The method employed is normative juridical research using a comparative law approach, based on the analysis of statutory regulations, legal doctrines, and relevant scholarly literature. The findings indicate that Indonesia adopts the dominus litis principle, which places the public prosecutor as the sole authority controlling prosecution, as regulated under the Criminal Procedure Code (KUHAP) and the Law on the Public Prosecution Service. This system reflects a centralized and formalistic prosecutorial structure. In contrast, Thailand implements a prosecution system that grants broader discretionary powers to prosecutors during the pre-prosecution stage and allows greater victim participation within criminal proceedings. These differences demonstrate Indonesia’s emphasis on legal certainty and institutional hierarchy, while Thailand prioritizes procedural flexibility and victim protection. This comparative analysis highlights the strengths and limitations of each system and provides valuable insights for the development and reform of prosecutorial authority within Indonesia’s criminal justice system through comparative legal perspectives.]]>
