The principle of trial concentration and direct speech are two different concepts, but there is a certain connection between them.
Trial-centrism refers to taking trial as the center and emphasizing the core position and role of trial in judicial procedure. Under the principle of taking trial as the center, the trial stage is the most important stage to determine the outcome of the case, and other stages such as investigation and prosecution should serve the trial stage.
The principle of direct words refers to the principle that the judge directly examines the evidence, the litigants argue orally in court, and personally contact and examine the evidence. The principle of direct verbal trial includes direct trial principle and verbal trial principle. The principle of direct trial requires that the defendant, public prosecutor and other participants in the proceedings must participate in the trial in person and have the ability to participate in the trial activities mentally and physically; The principle of verbal trial requires that court trial activities should be conducted in the form of verbal statements.
Under the trial-centrism, the principle of direct words can play a better role. Because the principle of direct words requires the judge to directly examine the evidence, the litigants can make oral arguments in court and personally contact and examine the evidence, which can enhance the fairness and transparency of the trial and improve the quality and efficiency of the trial. At the same time, the principle of direct words can also promote the active confrontation between the prosecution and the defense, protect the defendant's right to be defended by a lawyer, improve the legal aid system, and promote the formation of trial centralism.
