The article is devoted to the analysis of the registered draft Law of Ukraine «On Amendments to the Criminal Procedure Code of Ukraine in Terms of Ensuring the Implementation of the Functions of the Prosecutor's Office» № 3009a of August 26, 2020. In addition, the relationship between the standards of proof and the decision to initiate criminal proceedings (entry of information on criminal offenses in the Unified Register of Pre-trial Investigations (hereinafter – ERDR)) is highlighted. Moreover, the article studies such philosophical and legal categories as «probability» and «reliability» of a criminal offense circumstances existence. Analyzing the norms of legislative acts and the views of scholars, the authors present their own opinions on the possibility and expediency of enshrining in the Criminal Procedure Code of Ukraine the definition of «statement, notification of a criminal offense». The authors conclude that the statement or notification of a criminal offense should contain data on the circumstances that may indicate the commission of a criminal offense, however an indication of their «sufficiency» will not contribute to the proper implementation of the entry of information about the criminal offense in the ERDR. At the same time, it should be remembered that the pre-trial investigation, as a stage of the criminal proceedings, is designed primarily to ensure the implementation of the objectives of the criminal proceedings under Art. 2 of the CPC of Ukraine, by carrying out a comprehensive, complete and impartial establishment of the circumstances of the criminal proceedings on the basis of a sufficient amount of reliable, appropriate and admissible evidence obtained during the criminal proceedings. Therefore, imposing an obligation on the applicant to provide in the statement or notification of a criminal offense sufficient information about the circumstances that may indicate the commission of a criminal offense seems to contravene the principle of access to justice. In turn, paragraph 7-2 of Part 1 of Art. 3 of the draft law, which contains a requirement for the presence (submission) of sufficient data (information, evidence) by the applicant to confirm the commission of a criminal offense, at the stage of registration of the statements and notifications of a criminal offense with the subsequent entry in the ERDR, should be considered unreasonable and not conductive to the implementation of the objectives of the criminal proceedings declared in Art. 2 of the Criminal Procedure Code of Ukraine.
