An important purpose and value pursuit of the establishment of various litigation systems in criminal proceedings is to explore the objective truth of cases and make subjective judgments conform to objective reality to the greatest extent. The legal system of criminal evidence discovery can ensure that the prosecution and the defense exchange evidence information related to the case before the trial, and ensure that the prosecution and the defense are fully prepared for the trial, thus weakening the adverse effects brought by the confrontational trial method. "Cross-examination and authentication of criminal evidence through court trial not only ensures the objective authenticity of the case, but also ensures the substantive equality of the legal status of both the prosecution and the defense.
(two) to protect the defendant's litigation rights.
Undoubtedly, the right to know the evidence of the alleged crime before the people's court hearing is the concrete realization of the constitutional principle of "the defendant in criminal proceedings has the right to defense". The establishment of the criminal evidence discovery system enables the defendant to know the evidence supporting the prosecution through his defense lawyer, and enables the defender to refute the criminal facts accused by the procuratorial organ (hereinafter referred to as the prosecution) as the national procuratorial organ in the trial. At the same time, through the evidence discovery system, the defense can also know the evidence materials that the prosecution has in favor of the defendant, which will undoubtedly become a powerful reason to support the defense confrontation, thus ensuring the realization of the defendant's core litigation right-the right to defense. In this regard, the evidence discovery system has contributed a lot.
(three) to determine the focus of the case dispute and ensure the quality of the case trial.
Because the prosecution and the defense exchanged case information with each other before the trial and made full preparations, it is easy to promote the formation of the focus of controversy between the prosecution and the defense, and the cross-examination in court can also be targeted, and the case information contained in the evidence can also be fully exchanged during the trial. Undoubtedly, this is conducive to the formation of the trial judge's free evaluation of evidence, and is conducive to the court to form a correct judgment on the facts of the case and make a correct judgment. Only in this way can the adversarial trial mode be established in essence and the adversarial criminal proceedings be carried out smoothly.
(four) to ensure the efficiency of court proceedings and save judicial resources.
The legal system of criminal evidence discovery can not only ensure the continuity of court trial without the need to determine the focus of the case dispute and investigate and verify the evidence, but also make the judgment of the case conform to the objective reality to the maximum extent, let the defendant serve his sentence and reduce unnecessary appeals and appeals. In this way, it will undoubtedly greatly improve litigation efficiency, save judicial resources and ensure the realization of the principle of uninterrupted trial.
