Legal Literacy - This article discusses the meaning and relevance of the Dominus Litis principle in the criminal justice system in Indonesia. This principle indicates the position of the Prosecutor's Office as the controller of cases and the only body authorized to determine whether a case is worthy of being submitted to court according to the Criminal Procedure Code (KUHAP). This article also discusses the involvement of the Prosecutor's Office in the law enforcement process and how the application of this principle can improve the professionalism and integrity of Prosecutors in the eyes of the public in prosecuting criminal cases.

In order to realize justice and legal certainty and uphold human rights, the Prosecutor's Office as an institution in the field of prosecution in the criminal justice system participates and has strategic involvement. However, in reality, problems often arise in the Prosecutor's Office institution itself, such as the back-and-forth sending of case files from Police investigators to the Prosecutor's Office due to the rigid division of regions in the KUHAP. Whereas based on the Dominus Litis principle, the Prosecutor's Office is the main state organ in controlling cases and is the only institution that can determine whether a case can be submitted to the next stage. The implementation of this principle can be seen when the Prosecutor is given the authority to conduct investigations together with Police investigators.
