Corruption has emerged as one of Indonesia's most talked-about issues as a result of the debate over amendments to the KPK Law and the choice of a new institution's chairman, both of which prompted a surge of protests in the public sphere. The KPK Law's alteration appears to disregard public expectations, and it is thought that as a result of the amendment, the effectiveness of the agencies responsible for fighting corruption will be diminished. This study aims to assess the impact of Law Number 19 of 2019 regarding the KPK on eliminating corruption cases in Indonesia as well as any challenges that have appeared after the newest KPK Law's enactment. The research methodology employed in this study is empirical legal research. According to the study's findings, wiretapping, asset seizure, and search warrant authority were initially under the control of the Corruption Eradication Commission (KPK). The KPK might make arrests right away following a command from the leadership. A supervisory board's approval is required now that Law 19/2019 has been passed. The Supervisory Board is prohibited from acting as a vergunningsorgaan or licensor in accordance with Article 37B, paragraph 1 letter b of Law Number 19 of 2019, which states: "Giving permission or not giving permission to wiretapping, searching, and/or seizing" implies the Supervisory Board's discretion.
