Abstract: In a way, other evidence is unable to replace the role of forensic appraisal in current judicial practice. Forensic appraisal is also an important means to guarantee the fairness of judiciary. However, forensic appraisal service is chaotic due to the reform of forensic appraisal system. This is not only inconsistent with the function of the system, but also leading to occurrence of wrong cases, which has aroused wide attention.

The author expects that improvement can be worked out in these aspects.

摘要：  在某种程度上，其他证据已经无法取代司法鉴定在目前司法实践中的作用，其也是保障司法公正的重要手段。但是，自司法鉴定制度改革实施以来，司法鉴定服务乱象丛生，不仅与其本该具有的功能不相符合，甚至适得其反，成为导致错案发生的一大诱因，引起各界关注。在此从制度设计缺乏科学性、司法鉴定管理问题突出、市场化运行环境更是雪上加霜等三个方面讨论“乱象”产生的原因，以期能够鉴定制度能从这些方面得到完善。
