Under the background of rapid social transformation and rapid development, the special status of minors makes them enjoy a specific legal protection status. However, protection measures for individual minors are no longer sufficient to counter the increasingly complex and changing social risks. Therefore, we must strengthen and expand the means of protection to address the security challenges faced by an unspecified majority of minors. The newly promulgated Law on the Protection of Minors officially gives the procuratorial organs a legal status in public interest litigation involving minors, and the promulgation of this legal provision has laid a solid legal foundation for the establishment of the public interest litigation system for minors. The establishment of this system not only helps to thoroughly implement and implement the principle that is most beneficial to minors, but also can further expand the scope of protection, comprehensively and meticulously safeguard the legitimate rights and interests of minors, and ensure that they grow healthily and safely under the protection of the law. By sorting out the operation status of China's legal system, this paper sorted out the relevant cases in the past four years, read the relevant laws and regulations, analyzed the specific cases, and compared them with foreign legal systems. The results show that although the legal system of juvenile procuratorial public interest litigation has defects in both legislation and justice, There is still a certain gap between the implementation effect and social expectations.
