What is the relationship between civil procedure law, criminal procedure law and administrative procedure law?

Teacher Fan Chongyi said this: The three major procedural laws are all procedural laws, so many procedural principles, systems and procedures stipulated in the three major procedural laws are the same. For example, open trial, final trial of second instance, litigation in national language, trial supervision procedure and so on. However, the substantive problems to be solved by procedural law are different in nature. The criminal procedure law aims to solve the problem of whether a criminal defendant commits a crime and should bear criminal responsibility. The Civil Procedure Law aims at resolving disputes and disputes about civil rights and obligations between the parties, while the Administrative Procedure Law aims at maintaining and supervising the administration of administrative organs according to law and protecting the legitimate rights and interests of citizens and legal person organizations. The different tasks and purposes of the three major procedural laws make them different in litigation principles, systems and procedures. For example, in addition to courts, specialized agencies that preside over litigation also include public security organs, state security organs and people's procuratorates in criminal proceedings, and people's courts are the main ones in civil and administrative proceedings; Procedurally, criminal proceedings have investigation stages and compulsory measures to restrict personal freedom; In the evidence system, there are differences in the division of burden of proof and the requirements of proof standards; In the result of litigation, criminal responsibility is more different from civil responsibility and administrative punishment. ]
