In January，2018，General Secretary Xi Jinping made important instructions at the central political and legal work conference，and for the first time，he listed the deepening of intelligence construction with the promotion of Safe China，the rule of law and the construction of the team as the four major constructions of political and legal work，in order to further consolidate the overall situation of national security and social stability，and to further enhance people’s sense of happiness，well-being and safety. At the 2019 central political and legal work conference，General Secretary Xi Jinping emphasized that we should deepen the reform of the litigation system，and promote the classification of cases by their complexity，importance，and procedures，and promote the integration of scientific and technological innovation results such as big data and artificial intelligence with the judicial work. To promote the construction of an inter-departmental online collaborative case handling system is exactly one of the specific practices of the political and legal organs，who have been seeking power from science and technology，and promoting the modernization and standardization of law enforcement and case handling work with intelligence，in order to assist the reform of the judicial system.
