After the"phenomenon of litigation"explosion occurred,the courts faced pressure from"more cases and fe-wer people,"and the concept of"litigation source"governance was proposed and became a judicial policy.Grassroots courts participate in the litigation source governance through a series of institutional mechanisms such as the judicial policy of prioritizing mediation,the linkage mechanism of different mediations,the judicial confirmation of mediation agreements,and the judicial suggestion system.At different stages of conflicts and disputes,the role of courts in the litigation source governance varies.However,the implementation of roles in practice faces some difficulties,such as the poor effectiveness of grassroots courts urging other institutions to cooperate and collaborate,and the insufficient initiative of other institutions to resolve disputes under the leadership of the court.The successful example of"litigation source"governance is the con-struction and operation of"one-stop conflict and dispute mediation center"and"one code to resolve disputes"online platform.Its essence is to create new organizational platforms under the promotion of the political-legal committee,and aggregate resources for conflict and dispute prevention and resolution on the new platform.It is not the court that plays a leading role in this process,but the party committee and government.This type of litigation source governance model led by the party and government has played the advantages of the party-government system,vividly and vividly reflecting the principles of the relationship between the party and the law.The litigation source governance is led by the party committee and is the responsibility of the government,and the court participates and benefits from it,which fully demonstrates the practical significance of the"party-supported judicature."
