Party Secretary General Xi Jinping’s report to the Nineteenth National Congress of CPC points out that China will “carry out comprehensive and integrated reform of the judicial system and enforce judicial accountability in all respects”. Adhering to the leading role of science and technology is one of the basic principles that must be abided by in carrying out comprehensive and integrated reform of the judicial system. To realize the deep integration of the construction of intelligent court and the reform of the judicial system, China must complete the following tasks: first, solving the contraction between heavy case load and lack of staff; second, improving intelligent case-handling assistance system; third, imporving the relevant litigation systems; fourth, improving judicial services; fifth, strengthening trial supervision management; sixth, advancing the sharing and openness of data resources; and seventh, establishing an all-media intelligent public opinion management system. Generally speaking, the construction of intelligent courts has deepened the judicial openness, raised the judicial efficiency, and facilitated the litigation by praties and other participants in proceedings, and is conducive to the management of and supervision over administration of justice. Meanwhile, it has also posed many challenges to the ability of judges to use intelligent knowledge. Judges need to improve their capacity for collecting big data and for using big data to reduce and eliminate judicial discrepencies and to improve the fairness and efficiency of administration of justice. In the application of judicial big data, scientific conclusions can be ensured only if the data are objective and comprehensive. Therefore, China needs to establish not only a standardized mechanism for the management of the catelogues and life cycle of data, but also corresponding ethical principles on judicial technique. The utliziation of big data and artificial intelligence enables the judicial system to develop in a correct direction. In this process, attention should be paid to the underlaying issue of how to correctly hand the relations between standardization and individualization and between overall justice and justice in specific cases. In a time of informatization, administration of justice is undergoing a transition from a traditional one to an intelligent one. How to organically combine the two and develop the strong points and avoid the weak points of each of them in this process is a question that worths in-depth research.
