Conducting case-commentary research on the style of civil litigation documents is a key method for judges to produce legal documents, develop professional writing and creative skills, and enhance legal thinking. Such a study is an important way to deepen the reform of the judicial power operation mechanism and to improve the trial management mode. Considering the background of the judicial responsibility system reform, the localization of the research paradigms and case-commentary methods of the style of litigation documents can help reach the consensus of the legal professional community. It also helps promote judgment rules and the spirit of the law. Legal commentaries convey the important functions of public legal services to the public. It is necessary to integrate the Style of Civil Litigation Documents, the “one-stop” litigation service with the reform practice of judicial committees in China, and conduct detailed research on the procedural ruling function and guiding function of the style of civil litigation documents. By studying the guiding function of civil litigation document style for judicial behavior, litigation procedure, and entity processing, it is good for judges to broaden their ideas and methods to write civil litigation documents, enabling an examination of the localization path and method of the legal commentary research paradigm and demonstrating how to continue using the paradigm within the context of the comprehensive reform of the judicial system. Moreover, the study emphasizes how to exert the function of public legal services integrated with the style of civil litigation documents.
