公平与公正待遇的习惯国际法地位之否定

Negation of the status of fair and equitable treatment in customary international law

随着国际投资协定的数量与日俱增,公平与公正待遇已经成为一项普遍存在的待遇标准,但是否已经成为习惯国际法规则目前尚存争议。国际投资领域习惯国际法规则的确认不能仅仅考虑缔约数量。通过理性地把握“国家实践”和“法律确信”两项核心要素,充分认识到二要素的本质含义,并结合国际投资仲裁实践案例加以探讨,可以得出其尚未形成习惯国际法规则的结论。

With the increasing number of IIAs,fair and equitable treatment has become a universal standard of treatment.Whether it has become a rule of customary international law is still controversial.The confirmation of customary international law rules in the field of international investment should not only consider the number of contracting parties.By rationally grasping the two core elements of“State Practice”and“Opinio Juris”,fully recognizing the essential meaning of the two elements,and discussing the practical cases of international investment arbitration,we can draw the conclusion that they have not yet formed the rules of customary international law.
