This study aims to describe one of the political efforts of legal reform in the field of justice in Indonesia. This research describes that the presence or existence of norms that look at commissioner judges in preliminary examinations is part of an effort to prevent the possibility of the practice of abuse of roles or authorities that can damage the building of the criminal justice system with the modus operandi of violating the rights of suspects, whose role is more specific and has a value of certainty. compared to the role of judges in pretrial as it is today. This type of research in the problem of commissioner judges related to the ideals of legal reform is classified as normative juridical research or doctrinal research. The result obtained is that the existence of this commissioner judge is idealized to have a major impact on the reform of the performance model carried out by law enforcement officers at the fundamental level (investigation and investigation). The pattern of "judicial patronage" which can be understood as a pattern of placing law enforcement officers as masters, while suspects as objects, helpless figures, or "slaves" in the implementation of the criminal justice system, becomes an old disease or condition that reduces the conduciveness and progress of criminal justice, which by the role of the commissioner judge, is idealized to be curable.How to cite item: Satriya, B., Wahid, A., Primudyastutie, M.
