行贿人证言的证据法分析及使用规制

摘要

行贿人不同于普通证人,其证言也不同于普通证言.行贿人作为污点证人时,其证言的可靠性应当根据威胁、引诱的程度进行区分.庭审证言与庭前证言前后不一致时,要根据"彻底翻证型"或"部分翻证型"而采取不同的处理原则.在排除虚假可能性后,只有行贿人证言也可以单独证明受贿罪成立.在取证手段上,法律对非法行贿人证言具有比普通证言更大的容忍度,故非法行贿人证言的界定标准应当比普通证言更严.羁押、威胁、利诱、欺骗等取证方式并非必然构成非法取证,要根据是否导致行贿人丧失作证自主性而区别对待.%Bribers are different from normalwitnesses.Bribers' testimonies are different from ordinarytestimonies. Considering bribers are tainted witnesses, the reliability of their testimonies must be distinguished according to the degree of threat and seduce.When the in court testimonyis inconsistent with the out-of-court testimony, rules governing the admissibilityshould be distinguishedbetween the two situations ofOverthrowing-Testimony and Partly-overthrowing-Testimony. When the spurious possibility is eliminated,thesingle briber's testimonyis sufficient to convict the defendant of bribery. Asthe law bears greater tolerance to the briber's testimonythan the ordinarytestimony in scrutinizing illegality of the evidence obtaining means, it is necessary to establish a stricter test of the illegality of a briber's testimony. Detention,threat,seduce,and cheat are notabsolutefactors which would drive the evidenceconstituting illegally obtained evidence. The key factor that decides the illegality of the briber's testimony is whether the briberis deprived of autonomy.
