The government provides criminal law policies to someone who wants to be a whistleblower and a justice collaborator of corruption. The criminal law policy is enforced in Law No. 31 of 2014 as a complement to the weaknesses of Law No. 13 of 2006 and several other regulations. Regarding the amount of government appreciation given in the form of protection and appreciation, it is necessary to know how important the role of a whistleblower and justice collaborator is in uncovering the main criminal acts of corruption in assisting the criminal justice system in this country. This paper was carried out at the Witness and Victim Protection Agency. The data obtained are primary data and secondary data. Also, primary data collection techniques are also carried out by interviewing the parties concerned which are then analyzed descriptively. The data obtained is then processed and reviewed based on the formulation of the problem that has been applied so that it is expected to obtain a clear and concrete picture of the objects discussed qualitatively and subsequently presented descriptively namely explaining, elaborating, and describing by the problems closely related to this research. In giving testimony in general, the Justice Collaborator is motivated by a reduction in the period of detention or from his heart. Indeed he intends to repent. However, also in the testimony sometimes a Justice Collaborator is disturbed or hindered by his fellow friends who commit a crime, and this is what every country in the world needs to regulate so that the dismantling of a crime can run optimally. In responding to Corruption cases, countries in the world have reacted with various rules so that they can create a deterrent effect for the perpetrators of the crime, as well as the rules regarding Whistleblowers and Justice Collaborators they have included in their country's Law. However, in Indonesia, the rules regarding witnesses of new perpetrators and reporters are regulated in the 2011 Supreme Court Circular.
