出于对一些重要的社会关系的保护的考虑,英国和美国的制定法、判例法中都赋予了某些知晓案情的人以拒绝作证的权利,从而确立了保密特权原则。这与我国自汉代开始确立的“亲亲得相首匿”制度存在着某种暗合。纵横比较之下,我国的证据立法中确立证言特免权制度就有了一定的理论和现实基础。 In consideration of the protection of some important social relations, the enactment of laws in the United Kingdom and the United States and the case law give certain people who know the facts to refuse the testimony, thus establishing the principle of privilege. This is in line with the system of “pro-relatives and relatives” established in our country since the Han Dynasty. In comparison, there is a certain theoretical and practical basis for establishing the system of special testimonies in China’s evidence legislation.
