This research examines the overlap of competencies among oversight bodies in Libya, particularly the Audit Bureau, the Administrative Control Authority, and the National Anti-Corruption Authority. It focuses on practical conflicts between the Audit Bureau and the Administrative Control Authority, as well as the overlap between the Administrative Control Authority and the Public Prosecution. The study aims to clarify the legal boundaries of each body’s jurisdiction and analyze the impact of such overlap on the protection of public funds and institutional performance. The research adopts an analytical legal methodology, supported by comparative references where appropriate. It concludes that the multiplicity of oversight institutions does not necessarily enhance anti-corruption efforts unless accompanied by clear jurisdictional boundaries, mandatory coordination mechanisms, and effective information-sharing systems..............
