Since its establishment under the Anti-Corruption and Economic Crimes Act of 2003, the Ethics and Anti-Corruption Commission (EACC) in Kenya has pursued legal action to combat corruption, securing numerous convictions and some acquittals. Between 2003 and 2025, the EACC has achieved significant milestones in prosecuting corruption cases, though challenges like judicial loopholes and evidence collection have led to acquittals in high-profile cases.

Notable successes include the highest conviction rate was achieved in 2025 at 88.2%, with 30 convictions out of 34 finalized cases, marking a peak in prosecutorial success. The fiscal year 2018-2019 stood out with the highest number of convictions (51) and a solid 65.3% conviction rate. Other years, such as 2016-2017 (72%) and 2017-2018 (80%), also demonstrated strong conviction rates above 60%, reflecting consistent effectiveness in securing convictions. A perfect 100% conviction rate was recorded in 2013, albeit with only one case. The year 2019-2020 finalized the most cases (87), including 39 convictions, indicating significant judicial activity. Overall, with 408 convictions from 752 finalized cases, the data shows a commendable overall conviction rate of 54.2%, highlighting the need for stronger evidence and judicial coordination.
