This research aims to analyze the regulations regarding policies for determining witnesses and reconstructing policies for determining justice collaborators in corruption cases. The type of research used is normative, using an approach to laws and other regulations. The nature of the research is descriptive, using secondary data. Research analysis was carried out qualitatively using a deductive method of conclusion. This research concludes that, in practice, various regulations regulate the policy of determining cooperating witnesses or justice collaborators in criminal acts of corruption. This regulation began with laws and then developed into Circulars and Joint Regulations from law enforcement agencies. Due to differences in rules, the policy for setting new standards had to be changed. This standard must legally bind recognition or recognition and the same understanding or perception regarding the status of cooperating perpetrator witnesses or justice collaborators from the examination stage at the investigation level to the examination stage at the court level, even to the examination stage at the court level.
