Abstract: At present, there are a large number of problems in China's judicial expertise and the cross-examination of appraisal conclusions, which gives rise to a relatively advantageous position for the prosecutor in the cross-examination of appraisal conclusions. Since the cross-examination is the device to assure reliability of appraisal conclusions, it is essential to perfect the mechanism of the cross-examination of appraisal conclusions. And the Code of Criminal Procedure tends to reform the cross-examination of appraisal conclusions substantively. Under such circumstances, with the prosecutors’ dominant position called "easily cross-examine" challenged, prosecutors have to attach much importance to the new mode of cross-examination.

Key words: appraisal conclusion, cross examination, direct language principle

摘要： 目前我国司法鉴定和鉴定结论质证存在着大量的问题,导致公诉人在鉴定结论质证中处于相对优势地位。但是质证是保障鉴定结论可靠性的重要手段,要求完善质证机制,刑事诉讼法的发展趋势也必将对鉴定结论质证进行实质性的改革。在这种情况下,公诉人"轻松质证"的优势地位将面临挑战,如何应对全新的质证模式,已经是公诉人不得不重视的问题。
