Filed hundreds of public interest litigation (PIL) at different courts on issues, among others, environmental protection, gender equality, human rights, child rights, consumer rights, and good governance over the years and achieved significant milestones.

At present, Pro Public has been filing public interest litigation and pursuing cases related to civil liberty and human rights, gender and social justice and environmental rights since September 1994. Initially the program was supported by The Asia Foundation, Kathmandu, Nepal. Due to the good outcome of the project ARD/ USAID Rule of Law Project is also provided support for new cases and advocacy work of Public. Later Save The Children and OHCHR also supported for the intervention. Even when there is no support, Pro Public runs these interventions on its own.

A total of 60 environmental cases and 50 gender-based cases have successfully completed the court process, with a high success rate in decisions, while 15 cases on various other themes are currently ongoing.
