Legal analysis: First of all, the establishment of a defense system is conducive to ascertaining the truth and handling cases correctly. It is helpful for judicial organs to identify cases accurately and timely, apply laws correctly, and improve the quality of cases. Secondly, the defense system is an important guarantee for achieving procedural justice. The role of the defense system in realizing procedural justice is the most important manifestation of its significance. It is the full affirmation of this significance that gives the defense system an unshakable position in the modern criminal justice system. Finally, the defense system also has positive significance for legal publicity and education. In court, through the debate between the prosecution and the defense, the audience can understand the case, distinguish right from wrong, enhance their legal awareness, and at the same time enhance their recognition of the judgment, which is conducive to establishing judicial authority.
