判断测谎结论能否作为诉讼证据必须从证据的“三性”出发。合法性和客观性都不应阻碍测谎结论成为诉讼证据,更不能以真实性否定测谎结论的客观性;作为证据的本质属性,关联性的缺乏是测谎结论不能成为诉讼证据的根本原因。明确测谎结论的法律性质,方能更好其发挥人权保护功能和审查判断、获取其他证据的手段功能。 To judge whether polygraph conclusion can be taken as evidence of litigation must start from the “three nature” of evidence. Neither legitimacy nor objectivity obstruct the conclusion of polygraph detection as the evidence of lawsuit, nor can it negate the objectivity of polygraph conclusion with authenticity. As the essential attribute of evidence and the lack of relevance, the polygraph conclusion can not be the root cause of litigation evidence . To clarify the legal nature of the polygraph conclusion can we better exert the function of human rights protection and reviewing judgments and obtaining other evidence.
