The application of the constitution is an important way to reflect the supreme legal validity of the constitution. However, the unavailability of the Chinese constitution has greatly affected the constitutional authority and effectiveness. The effective application of the U.S. constitution has brought its constitutional concept deeply rooted in the hearts of the people, which is closely linked with the fact that the U.S. Constitution is an important source of its civil procedure law. This article deeply analyzes and discusses the origins of the constitution of the U.S. Civil Procedure Law as well as its causes and implications, and hopes that it will be helpful to the study of constitutional justice in China.
