论国际投资仲裁中贿赂行为的证明标准

对于贿赂行为的证明标准,国际投资仲裁庭的倾向是从回避到明确借鉴传统商事仲裁中的＂更高证明标准＂。然而,国际投资仲裁与国际商事仲裁存在较大的区别。支持国际商事仲裁庭采用＂更高证明标准＂的传统理由及潜在动机在国际投资仲裁中并不存在。因此,在国际投资仲裁中采用＂更高证明标准＂的法律依据不足。建议中国在BIT中将贿赂作为不可仲裁的投资争端事项之一加以规定,或者明确规定应采纳的证明标准。如中国作为被申请方参加国际投资仲裁程序,应该主动与仲裁庭讨论关于贿赂的证明标准问题,以争取有利条件。

The Standards of Proof for Bribery in International Investment Arbitration

As to the standards of proof for bribery,the international investment arbitration tribunals tend to adopt the higher standard of proof used by international commercial tribunals from remaining silent before.However,international investment arbitration differs greatly from international commercial tribunal.The traditional reasons and unconscious motives,on which ＂the higher standard of proof＂ is based by international commercial tribunals,do not exist in international investment arbitration.Thus,there are no legal grounds to adopt the higher standard of proof in international investment arbitration.The author suggests designating bribery in BIT as one of the disputes matters with which arbitration is unavailable,or explicitly stipulating the appropriate standards of proof in BIT.As a possible respondent in international investment arbitration proceeding,China should discuss the standard of proof for bribery with the Tribunal at an early stage to achieve favorable conditions.
