最近美国政府和学界对WTO争端解决实践,尤其是涉美贸易救济争端解决结果不满,指责WTO专家组/上诉机构在进行“司法解释”时增加美国相关协定项下的义务,或减损其权利。笔者通过分析认为,美国政府对WTO“贸易救济”争端解决挞伐的实质是指责专家组/上诉机构的“司法能动性”、僭越其解释权限。WTO专家组/上诉机构并没有越权裁判,美国对WTO争端解决机制的指责和修改动议反映了美国的主权防卫。 Recently, the U.S. government and academia have been dissatisfied with the WTO dispute settlement practice, especially the settlement of the dispute over trade remedy in the United States. They accused the WTO panel / appellate body of increasing or decreasing the obligations under the relevant U.S. agreements when conducting “judicial interpretations” right. According to the author’s analysis, the essence of the U.S. government’s ruling on WTO “trade remedy ” disputes is to accuse the panel / appellate body of “judicial initiative” and to interpret its authority. The WTO panel / appellate body did not have ultra vires judgment. The U.S. accusation and amendment to the WTO dispute settlement mechanism reflected the U.S. sovereignty defense.
