Abstract: The article is devoted to analysis of the Prosecutor's status as a subject of proof in the pre-trial proceedings. It describes in detail the Prosecutor's participation in the collection of evidence, their interaction in the process of proving alongside the bodies of investigation and inquiry. Based on the analysis of provisions of the applicable legislation, the orders of the Prosecutor General of the Russian Federation and various points of view of experts in this field, the article puts forward and substantiates the conclusion that the Prosecutor must exercise their authority as a prosecution subject of proof to the fullest extent. In this regard, it is proposed to supplement the Criminal Procedure Code of the Russian Federation with a number of provisions granting the Prosecutor the right to consider and resolve the petitions of the participants in the criminal case, take part in the investigative actions, give the investigator the mandatory instructions, as well as submit the documents and materials received during the Prosecutor’s investigation to preliminary investigation agencies. All of the proposals are closely interrelated and strictly comply with the legal nature of the Prosecutor's supervision.

Abstract: The research subject is the set of legal norms (criminal procedural norms and the Federal Law “On the public prosecution office of the Russian Federation”) regulating the activities of the prosecutor in criminal prosecution and supervision over the procedural activities of pre-trial investigation agencies (agencies of inquiry and preliminary investigation) on the stage of a criminal case opening, and the practice of their use. The author also analyzes theoretical insights of scholars, studying the prosecutor’s supervision theory, concepts and ideas about the issues in question. The author applies general scientific and special research methods. The author analyzes the ideas of theorists and practitioners about the problem in question, using the officially published data about the crime rates and supervisory activity of prosecutors. The prosecutor’s authorities are considered in their historical development as a whole system of interrelated rights and responsibilities, ensuring the protection of public interests in criminal proceedings and guaranteeing citizens’ rights. The article proves that the prosecutor’s authorities to supervise over the procedural activities of agencies of pre-trial investigation on the stage of a criminal case opening are not effective, because the prosecutor, using these authorities, doesn’t have a real capacity to eliminate the revealed violations of the law. The author’s suggestion to change the provisions of the criminal procedural code will allow the prosecutor to not only raise the question of violations elimination, but eliminate them personally, opening a criminal case and timely and effectively protecting the rights of complainants.
