Public Interest Litigation (PIL) is the major and most influential judicial innovation in the Indian judicial system, which gives the power to the people to claim their right in matters that affect society as a whole. Previously, only the aggrieved party had the right to file a case in the court. But now, any citizen or organization with public-mindedness can move the court through a PIL asking for the enforcement of general rights and constitutional accountability.
Judiciary has turned into the main defender for the voiceless people due to PILs, thus the judiciary is protecting human rights, fighting corruption, and fostering social and environmental changes.
Why Public Interest Litigation (PIL) Matters Today?
- In over a decade of handling public law matters, one truth stands out, PILs give ordinary citizens a voice when the system fails them.
- From pollution to prisoners’ rights, these petitions have redefined justice in India.
- It is seen how a simple letter or petition, filed in public interest, can change lives, a slum getting clean water, a local factory forced to install waste treatment, or a hospital directed to provide free emergency aid.
- That is the real power of Public Interest Litigation (PIL): justice not just for one, but for all.
What is a Public Interest Litigation?
A Public Interest Litigation (PIL) is a legal petition made to protect the rights of the people, or a large segment of society. Unlike a regular action, a PIL is brought for a cause affecting others.
Unlike regular actions, any interested citizen, or organization, can bring a PIL, seeking enforcement of public duties and constitutional rights.
According to Indian law, a PIL can be filed in front of:
- The Supreme Court, under Article 32, (protection of fundamental rights), and
- The High Courts, under Article 226 (protection of legal and constitutional rights).
This means that justice is available to anyone prepared to seek enforcement of rights, without regard to position or resources.
Main Objectives Behind PIL
Public Interest Litigation was never meant to be an academic concept. Its objectives are deeply practical:
- To make justice accessible to downtrodden and oppressed people.
- To keep governmental organizations responsible for a lack of action or abuse of power.
- To safeguard inherent rights such as equality, life, and liberty.
- To put social, environmental, and governance failures to light.
- To motivate citizens to take part in government.
In essence, PIL rallies public resentment into litigation.
Who Can File a PIL: Can You Do It Too?
Yes, any Indian citizen or NGO acting bona fide can file a PIL for the public good.
Eligible Petitioners
- Citizens, or NGOs as representatives of a social cause.
- Activists/lawyers/journalists shining light on injustice.
- Groups working in labour/environment/human rights.
Respondents
- Central or State government: any form of municipal authority/public body.
- Government-run entities, such as schools/hospitals.
Private entities can be included only if they perform a public benefit duty (e.g. a private withhold emergency treatment).
Real Filing Process: Step-by-Step
Having filed and assisted in innumerable PILs, here is how the filing/procedure actually functions:
Step 1: Find a valid cause concerning the public
For example: the environment, illegal buildings, health/safety violations, or basic right denials
Step 2: Get the proof
Photo, documents, RTI, expert report, or other evidence reinforcing your claim
Step 3: Write the Petition
This should include:
- the court name (Supreme Court or High Court)
- names of the petitioner and respondent
- statement of facts, grounds, and specific relief sought
- reference to relevant constitutional articles (32 or 226).
Step 4: Serve Notice to the Authorities
You should allow the department concerned to respond before you file in order to add credibility to the case.
Step 5: File the Petition
- For a High Court petition, submit two copies
- For a Supreme Court petition, submit five copies along with proof of service to the respondent.
Court Fee: ₹50 per respondent which is inexpensive, even symbolic. In a number of PILs, the court even appoints an amicus curiae (a friend of the court) in order to ensure that a fair hearing takes place.

Why PILs Are So Important in India?
1. They Make Justice Accessible
PILs open courtroom doors to those who could never afford a lawyer. They make justice participatory, not privileged.
2. They Keep Governments Accountable
PILs force government departments to act lawfully. Many anti-corruption and human rights reforms started from PILs.
3. They Protect Fundamental Rights
From prisoners’ rights to environmental protection, PILs have turned constitutional promises into realities.
4. They Drive Environmental and Social Change
Every major pollution control directive in India, Ganga cleanup, emission control, industrial safety, began with a PIL.
5. They Strengthen Democracy
By promoting judicial review, PILs ensure that no authority is above the Constitution.
Challenges and Misuse of PIL
While PILs empower citizens, they are not free from misuse.
- Frivolous petitions filed for fame or harassment.
- Judicial overreach where courts step into executive decisions.
- Delay in enforcement when agencies ignore court orders.
The Supreme Court has repeatedly warned that “PIL should not become a tool for publicity.”
A Lawyer’s Insight: When a PIL Works Best
From experience, PILs succeed when:
- The issue is backed by solid documentation.
- The petitioner has no personal gain.
- There is media or public awareness supporting it.
In one PIL, the law firm filed regarding illegal dumping of waste near Delhi, a single order from the High Court forced the local authority to install waste treatment plants within six months. Hundreds of families benefited.
That is what makes PILs special: they make the law come alive for people who never imagined courts would listen to them.
Conclusion
Public Interest Litigation (PIL) has altered the legal framework in India by causing courts to become the guardians of constitutional values. But, like any powerful tool, it must be wielded appropriately.
As practitioners, we have a responsibility to file PILs with good faith, evidence-based facts, and a true public interest objective. If wielded appropriately, PILs will continue to provide that justice in India remains “by the people”, “for the people”, and “of the people.”
