Why should the new civil procedure law restrict citizens' agency rights?

Since the reform and opening up, China's lawyer system has been restored and continuously reformed. However, some citizens who know a certain amount of legal knowledge but don't have the qualifications of lawyers and don't work in legal service institutions, driven by economic interests, go to the society to sue. These people are not subject to the management and restriction of any organization or unit, and represent others in litigation and seek economic benefits (agency fees). They even picked lawsuits, forged evidence, bribed court staff and illegally charged fees for economic benefits, which disrupted the litigation order and affected the construction of a harmonious society. These illegal acts, which are called "black lawyers", are very hidden and difficult to investigate. Moreover, people's legal awareness and knowledge have been greatly improved, and the number of legal service institutions (law firms and legal service offices) has also increased greatly. Ordinary citizens no longer need to be agents of the parties. This provision of the new people's procedural law is conducive to further strengthening the norms of litigation order, serious law and discipline, and enhancing judicial fairness and justice. Those who have certain legal knowledge and are interested in engaging in the legal profession should strengthen their study, join and organize legal service institutions according to law, make contributions to the construction of socialist rule of law in China aboveboard, and get economic remuneration according to law.
