证人特权是指在特定范围内,具有作证义务的人,基于特定身份、特定原因,依法享有的拒绝作证的权利,其内涵与证人能力、证人作证豁免权有显著的差异。英美法系和大陆法系的国家大多对证人特权有法律规定,只是详略不同,其内容包括不强行自证其罪的特权,基于配偶亲属关系而享有的特权,基于职业秘密而享有的特权,基于公务秘密而享有的特权。我国应基于证人特权的合理性与传统的社会伦理道德要求,顺应国际司法的潮流,完善我国的刑事诉讼体系,对证人特权做出详细的法律规定。 Witness privileges refer to those who have the obligation to testify in a specific scope and have the right to refuse to testify on the basis of specific identities and specific reasons. Their connotations are significantly different from those of witness testimony and witness testimony immunity. The Anglo-American legal system and civil law countries mostly have legal provisions on the privilege of witnesses, but they differ only in their details. They include the privilege of not guilty of self-incrimination, the privilege of being based on the spouse’s kinship and the privilege of being based on a professional secret , Privileges based on official secrets. Based on the rationality of witness privilege and the traditional social ethics and moral requirements, our country should follow the trend of international judicial system, improve our criminal procedure system and make detailed legal provisions on the privilege of witnesses.
