狭义的瑕疵证据是指具备了客观性、关联性但在合法性要件方面存在瑕疵的证据。在审查起诉实践中,瑕疵证据在物证、书证、犯罪嫌疑人供述、辨认笔录、侦查机关出具的情况说明等方面均有所体现。因此在审查起诉阶段,发现并要求侦查机关对瑕疵证据作出补强是检察人员的一项重要工作。 Narrow evidence of blemish is evidence of objectivity, relevance, and flaws in the element of legitimacy. In the review and prosecution practice, the evidence of defects is reflected in the material evidence, documentary evidence, the confession of criminal suspects, the record of identification and the statement of circumstances issued by the investigation organ. Therefore, it is an important task for prosecutors to find and require the investigating organ to reinforce the evidence of defects during the prosecution and prosecution phases.
