刑事诉讼瑕疵证据问题研究
Research on the Problem of Defective Evidence in Criminal Procedure

瑕疵证据是极具中国特色的法律概念，一般指的是以侦查人员为主的司法人员在证据收集和制作过程中存在轻微违法行为而形成的证据。瑕疵证据具备轻微违法性、可补救性以及法律效力待定性等鲜明特征，是深刻反映我国国情、贴合司法实践的证据类型，因而我国当前司法实务中对瑕疵证据及其补救表现出较为积极的态度，瑕疵证据经过补救后恢复证明能力并最终被采用的比例较高。但由于我国瑕疵证据制度尚不完善，实践过程中存在认定范围不清晰、补救程序不规范等问题，因此从瑕疵证据基础理论出发，借助对瑕疵证据制度运用现状的分析，多角度提出帮助瑕疵证据制度更好发挥其应然作用的可行性建议，具有极强的现实意义。
Defective evidence is a legal concept with Chinese characteristics, which generally refers to the evidence formed by judicial personnel, mainly investigators, who have minor illegal acts in the process of collecting and producing evidence. The defective evidence has the distinct characteristics of slight illegality, redeemability and undetermined legal effect. It is a type of evidence that profoundly reflects China’s national conditions and conforms to judicial practice. Therefore, the current judicial practice in our country shows a more positive attitude towards defective evidence and its remedy, and a higher proportion of defective evidence recovers its proof ability after being remedied and is eventually adopted. However, due to the imperfect evidence system in our country, the scope of identification is not clear and the remedial procedures are not standardized in the practice process, so it is highly realistic to start from the theory of defective evidence base and make feasibility suggestions to help the defective evidence system better play its role by analyzing the application status of the defective evidence system.
