Powers are exclusively established to preserve and protect human rights and freedoms, but there is a serious violation of human rights and freedoms, which occur with irreparable consequences. One of the modalities to increase the level of legality, professionalism and accountability of police officers is control. The focus of this work is the internal control of the police embodied in police oversight resolving complaints. The aim is to show the importance of the role of the control of the police, as well as the problem-oriented aspects perceive the way of keeping the complaint procedure and present certain difficulties and specificities that make its implementation. Also, the present work is aimed at determining the appropriateness of keeping the complaint procedure from the position of a citizen, who complains that his rights or freedoms are violated.
