Public Interest Litigation: Meaning, Features & Key Cases

Public Interest Litigation

Public Interest Litigation (PIL) has emerged as a revolutionary concept in Indian constitutional jurisprudence. It allows any public-spirited individual or organization to approach the courts for redressal of public wrongs or enforcement of public duties. The idea of Public Interest Litigation goes beyond personal interest and facilitates access to justice for disadvantaged groups.

Public Interest Litigation

The concept of Public Interest Litigation in India originated as a judicial innovation aimed at promoting social justice. It democratizes access to the courts, especially for the poor and marginalized who might not have the resources to seek redress. Public Interest Litigation was pioneered by the Supreme Court of India during the late 1970s and early 1980s under the leadership of Justice P.N. Bhagwati and Justice V.R. Krishna Iyer.

Overview of Public Interest Litigation

The Public Interest Litigation mechanism empowers any individual or NGO to file a case in the public interest. It serves as an essential tool in the hands of civil society to correct administrative injustices and influence policy reform. The courts allow PILs even based on letters or postcards from concerned individuals, making it a flexible and citizen-friendly legal avenue.
