在办案实践中,我们常常会遇到法人提供有关案情的证明材料。此类证明材料在认定犯罪事实、被告人社会背景、印证其他证据证明力等方面,往往起着重要的作用。然而此类材料究竟有否证据效力,以及如何搜集、采信问题,始终是个“模糊概念”,给执法活动带来了许多操作上的困难。 In handling cases, we often encounter legal entities to provide evidence of the case. Such proof materials often play an important role in determining the facts of crimes, the social background of defendants, and proving the proof of other evidences. However, whether such materials have any evidence and effectiveness and how to collect and collect information has always been a “vague concept”, posing many operational difficulties for law enforcement activities.
