Since 2014，in order to improve the public interest litigation’s legal supporting system，13 provinces began to implement the “Procuratorial organs filed public interest litigation reform pilot program”，public interest litigation in the environmental rights，consumers’ rights and other interests made new progress. However，the concept of public interest litigation needs to further spread，the legal status，procedure and scope of the public interest litigation filed by the procuratorial organs should be improved，the type of social organization of public interest litigation should be specific，the professional ability of the social organization to field the public interest litigation is seriously insufficient. Innovate the idea of public interest litigation and develop the idea of public interest litigation to protect to the human rights，complete the procedure mechanism of the procuratorial organs to institute public interest litigation and strengthen judicial guarantee of human rights，enlarge the range of social organizations to institute the public interest litigation and strengthen the professional construction of social organizations，orderly coordinate to promote the development of public interest litigation and promote the standard of judicial guarantee of human rights.
