在案件侦查、审查逮捕或审查起诉的过程中,常常遇有犯罪嫌疑人翻供、不供,证人翻证或不如实作证,以及相互串供等特殊情形。这往往增加了办案的难度,能否处理好这类案件,不仅是对办案人员综合素质与能力的检验,而且也是确保办案质量的关键所在。因此,强化对疑难刑事案件证据的审查就显得尤为重要。 In the process of investigating and examining arrests or examining and prosecuting cases, they often encounter special cases such as criminal suspects’ giving or refusing to give evidence or witness testimony or false testimony. This often increases the difficulty of handling a case and whether it can handle such a case is not only a test of the overall quality and ability of investigators but also the key to ensuring the quality of the case. Therefore, to strengthen the review of evidence in difficult criminal cases is particularly important.
