Public Interest Litigation (PIL) in India has transformed the way justice is delivered, making the legal system accessible not just to individuals directly affected but to any citizen concerned about public welfare. With the growing complexities in governance, administration, and social issues, PIL serves as a powerful tool for safeguarding constitutional rights and addressing collective grievances.
What is Public Interest Litigation (PIL)?
Public Interest Litigation (PIL) refers to legal actions initiated in a court of law for the protection of public interest rather than private rights. Unlike traditional litigation, where the petitioner must have a direct personal stake, PIL allows any concerned citizen or organization to seek judicial intervention for issues that affect the larger public.
The term public interest litigation reflects its objective: safeguarding rights and interests of the community, particularly vulnerable and marginalized groups who may lack resources or awareness to approach the courts themselves.
The public interest litigation definition in legal terms revolves around actions taken to serve the general welfare, uphold constitutional rights, ensure administrative accountability, and promote social justice.

History and Evolution of Public Interest Litigation in India
The concept of public interest litigation originated in the United States in the 1960s during the civil rights movement. In India, public interest litigation started in India during the late 1970s and early 1980s as part of judicial activism.
The Indian PIL movement was pioneered by Justice V.R. Krishna Iyer and Justice P.N. Bhagwati, who relaxed the rule of locus standi (the right to file a case), allowing socially conscious citizens to file petitions on behalf of the affected sections of society. Justice P.N. Bhagwati is often acknowledged as the father of PIL in India, due to his pioneering rulings that enabled socially conscious citizens to access high courts for public interest matters.
Landmark Early PIL Case:
- Hussainara Khatoon v. State of Bihar (1979): This case exposed the plight of undertrial prisoners and led to sweeping reforms in India’s criminal justice system. It is widely regarded as one of the first instances of public interest litigation in India.
Over the years, public interest litigation cases in India have expanded to cover environmental law, human rights, administrative law, corruption, education, health, and more.
Why Is It Called Public Interest Litigation?
It is termed Public Interest Litigation because:
- It seeks to protect broader public interest rather than individual grievances.
- It promotes social justice by giving voice to weaker sections.
- It ensures government accountability and good governance.
- It allows citizens to challenge policies, administrative actions, or failures impacting the public at large.
In short, it serves the public interest by ensuring that constitutional rights are upheld for all, not just a few.
Importance and Objectives of Public Interest Litigation
The objectives of public interest litigation include:
- Protecting Fundamental Rights: Ensuring rights guaranteed under Part III of the Indian Constitution are not violated.
- Judicial Oversight: Holding government and public authorities accountable for dereliction of duty.
- Providing Access to Justice: Allowing even the poor and marginalized to seek legal redressal.
- Correcting Administrative Failures: Addressing cases of environmental degradation, corruption, or public safety lapses.
In a country like India, where social inequalities are significant, public interest litigation in administrative law and environmental law has brought sweeping changes.

Despite its benefits, PIL is not without criticism:
- Frivolous Petitions: Increasing misuse for personal or political motives.

It continues to evolve through reforms like PIL guidelines and stricter admission standards. Far from just law, PIL remains a tool for democratic empowerment — when wielded judiciously.
