论国际投资仲裁中非排除措施“必要性”的审查

On the “Necessity” Review of Non-Precluded Measures in International Investment Arbitrations

基于国际社会在投资条约内非排除措施条款的自我判断性质认定上的严重分歧以及在"即便是自我判断性质的条款(包括明示的自我判断条款与默示的自我判断条款),也不能全然置身于争端解决机构的审查范围(包括实体与程序方面)之外"问题上的大致共识,建议淡化非排除措施条款的自我判断性质区分。国际仲裁庭应在非排除措施的"必要性"审查事项上采纳合理的"最少限制方式"或遵从的"最少限制方式"审查标准。

Owing to the severe divergence on the issue of determining self-judging nature of the non-precluded measures causes in investment treaties and the generally common recognition on ＂even if the self-judging clauses（ including the explicit ones and the implicit ones） cannot be totally exempt from the reviewing by the dispute settlement bodies in terms of the substantive as well as the procedural aspects＂within the international community,it is recommended not to emphasize the distinctions between the non-precluded measures by their self-judging features. With regard to the ＂necessity＂review of the non-precluded measures,the international investment arbitral tribunals are suggested to adopt the reasonable ＂least restrictive means＂or deferential＂least restrictive means＂criteria.
