Public Interest Litigation (PIL) in India, initiated in the 1980s by V.K. Krishna Iyer and P.N. Bhagwati, enables citizens to seek justice for social issues affecting the public at large, despite not being explicitly mentioned in the Indian Constitution. It serves as a legal tool for marginalized communities and can be filed by individuals or organizations for broader societal concerns, often resulting in landmark judgments that advance public rights. However, the Supreme Court has established guidelines to filter out frivolous PILs, specifying which matters will be entertained, such as issues of bonded labor, environmental pollution, and harassment.
