在民事诉讼活动中,诉讼活动需要由当事人来启动,裁判文书的拘束对象也必须是适格的当事人。但由于种种原因,起诉时所确定的当事人在后来的诉讼中可能发生变化,即当事人变更。通过这一讨论提出问题,欲就当前审判实践中当事人变更方面的司法理念进行研究,并进一步分析制定当事人变更规则时应当遵循的符合现代司法理念的基本原则。 In civil litigation activities, litigation activities need to be initiated by the parties, and the subject matter of referee instruments must also be appropriate parties. However, due to various reasons, the parties identified in the prosecution may change in subsequent litigation, that is, the parties change. Through this discussion, I put forward some questions to study the judicial concept of the parties involved in the current judicial practice and further analyze the basic principles that should be followed in the process of formulating the rules for changing parties.
