This research was conducted to analyse the prohibition of former corruptors’ ability to become legislative candidates based on PKPU Policy Number 20 of 2018, in terms of synchronizing the policy with higher laws and examining it from the perspective of political ethics and legal politics in eradicating corruption in Indonesia. The research method adopted was normative juridical, and the types and sources of data used were secondary data, applying data sources from primary, secondary, and tertiary legal materials. The results of data processing are presented in the descriptive analysis. The outcomes of this research indicate that the synchronization of PKPU policy law No. 20 of 2018 regarding the disallowance of ex-corruptors from becoming legislative candidates clash with higher laws and regulations, namely Law Number 7 of 2017 regarding elections in conjunction with Law Number 12 of 2011 about the formation of laws and regulations. Therefore, the conclusion of the KPU regulations has no binding legal force. The actualization of a fair and sovereign election requires all policymakers’ support, especially in the enforcement and application of political ethics and the law to eliminate corruption in Indonesia.
