证据,无论在国内法还是国际法上,都是查明案情,确认事实的不二手段。而对证据的裁量,由于很难用确定的标准加以规定,很大程度上依赖于法官的自由裁量。国际法上的证据究竟以何标准进行判定,这是一个在法学理论和司法实践上都不断进步的问题。本文主要以卡塔尔与巴林案、马来西亚与新加坡白礁案中有关证据证明标准的内容为切入点,尝试着探究一下国际法中的证据证明标准问题。 Evidence, both in domestic law and in international law, is the only means of ascertaining the facts of the case and of confirming the facts. Discretion of evidence, however, is difficult to set by a definitive standard and relies heavily on a judge’s discretion. It is a matter of continuous improvement in the jurisprudence theory and judicial practice that the standards of evidence in international law should be judged. This article mainly focuses on the content of relevant standards of proof in Qatar and Bahrain, Malaysia and White Reef Incident in Singapore, and tries to explore the standard of proof in international law.
