论刑事诉讼中DNA鉴定结论的证据效力

The Evidentiary Effect of Forensic DNA Identification in the Criminal Litigation

DNA鉴定解决了困扰司法鉴定多年的“同一认定”的技术难题。DNA鉴定结论能为刑事诉讼提供有力证据,但它仍然是证据的一种,并非“铁证”,盲目迷信DNA鉴定具有危险性。应该审查DNA鉴定的偶然重复性、污染可能性、鉴定水平的差异性、鉴定书的规范性,以及与其他证据的关联性。DNA鉴定结论只有与其他相关证据相印证后才可以作为证据予以采信,其证据效力必须经过审判人员对全案证据进行综合审查并采信后才能体现。

Forensic DNA identification solved the ＂estabishing identity＂ technical problem that has puzzled jurdicial identification for many years. Forensic DNA conclusion can be the effetive evidence for criminal action, but it is only a kind of evidence, not irrefutable evidence. So it is dangerous to believe blindly in forensic DNA identification. We should examine forensic DNA identifications accidental repetition, polluted possibility, difference of identification level, standard of appraisal certificate and relation with other evidence. Forensic DNA identification conclusion can be adopted only when it is confirmed with other evidence and the evidentiary effect can be embodied only after the judges＇ comprehensive investigation of the whole evidence.
