在WTO争端解决机构的实践中,非政府组织以法庭之友的身份向专家组和上诉机构提供书面陈述的现象屡见不鲜,专家组和上诉机构对其态度经历了逐步开放的过程。结合实践,笔者以非政府组织为例阐述了“法庭之友”在WTO争端解决机制中的合理依据和实践支持,进而分析法庭之友的应有定位。 In the practice of the WTO Dispute Settlement Body, it is not uncommon for non-governmental organizations to provide written statements to the panel and the appellate body as a member of the court. The attitude of the panel and the appellate body has undergone gradual opening up. Combining with the practice, the author illustrates the reasonable basis and practical support of “Friends of the Tribunal ” in the WTO dispute settlement mechanism by taking non-governmental organizations as an example to analyze the proper orientation of the courtroom friends.
