<![CDATA[The development of Indonesia's financial sector requires legal safeguards that not only promote financial stability but also preserve the integrity of criminal law enforcement. Article 50A of Law Number 4 of 2023 concerning Financial Sector Development and Strengthening (P2SK Law) raises important juridical questions regarding its role in preventing the obstruction of material truth by law enforcement officers. This study aims to examine the legal implications of Article 50A and its relationship with the principles of material truth, due process of law, legal certainty, accountability, and the rule of law within Indonesia's criminal justice system. The research employed a qualitative method using an empirical juridical approach based exclusively on documentary research without involving human participants or field observations. Data were collected from primary, secondary, and tertiary legal materials, including statutory regulations, judicial decisions, official institutional reports, and scholarly publications, and were analyzed using the interactive qualitative model developed by Miles, Huberman, and Saldaña. The findings indicate that Article 50A serves as an important legal safeguard for maintaining the integrity of criminal investigations and strengthening the protection of material truth. Documentary evidence further demonstrates that obstruction of material truth encompasses not only direct interference with investigations but also abuse of authority, evidence manipulation, witness intimidation, conflicts of interest, procedural irregularities, and institutional interference that compromise investigative independence. Moreover, the effectiveness of Article 50A depends upon consistent judicial interpretation, institutional oversight, professional ethics, and comprehensive accountability mechanisms applicable to law enforcement officers. In conclusion, Article 50A of the P2SK Law reinforces constitutional principles by integrating legal certainty, institutional accountability, and the protection of material truth within Indonesia's criminal justice system.]]>
