The avoidance of judicial expertise is an important part of the judicial expertise system. At present,there are some problems and deficiencies in the application of the judicial expertise avoidance system, suchas the lack of basis for the avoidance of judicial expertise institutions, the subject scope of the right to applyfor avoidance is too narrow, too general and vague, and the shortage of avoiding procedural rights. The aboveproblems all restrict the development of the judicial expertise avoidance system to some extent, and even reducethe efficiency of litigation, which is not conducive to the healthy development of the judicial system. Therefore,in order to realize the original intention of the avoidance system and improve the operability of the avoidancesystem, the legislature and the competent judicial authority should optimize the avoidance system according tojudicial practice and promote the perfection of the judicial avoidance system.
