口供是一种最为流行的证据,它对犯罪案件的侦破、准确起诉和公正审判具有可以言说的重要作用。但是,要取得与案件事实相符的真实口供往往较难。这表现在两个方面,一是取得自愿认罪的口供不易,一是自愿认罪的口供也存在着自诬伪证的情形。这样,口供的真实性与否以及口供和定罪之间的关系,就成为一个值得认真对待的问题。 Confession is one of the most popular evidence, and it can play an important role in the detection of criminal cases, accurate prosecution and fair trial. However, it is often more difficult to obtain true confessions consistent with the facts of the case. This is manifested in two aspects. One is that confessions obtained through voluntary confession are not easy, and the confession of voluntary confession also exists in the form of self-accusation and perjury. In this way, the authenticity of the confession and the relationship between confession and conviction become a matter that deserves serious consideration.
