The number of criminal court trials is constantly decreasing, as the domestic legislature has introduced a number of legal institutions aimed at diverting criminal cases from the court system, or avoiding charging. Nevertheless, there will always be crimes, the adjudication of which cannot dispense with impeachment based on direct judicial investigation. The trial is undoubtedly the "highlight" of the criminal proceedings, since it is here that the adversarial process takes place in its entirety, and here the defense counsel and the prosecutor have the opportunity to form opinions on factual and legal issues in each other's personal presence. The amendment of the Criminal Procedure Act naturally raised many questions, such as who in the near future will actually control the evidence taken in court proceedings, and what basic procedural rights should be provided to the participants of the proceedings. In this study, I would like to reflect primarily on these questions, based on some ECtHR decisions.
