Key takeaways

Public Interest Litigation (PIL) allows any member of the public to seek a legal remedy on issues affecting the public at large.
It was developed in the late 1970s and 1980s by the Supreme Court of India to give citizens better access to justice.
It is enforceable under Article 32 (Supreme Court) and Article 226 (High Courts) of the Constitution of India.
The petitioner does not need any direct personal interest; a public-spirited person can file in good faith.
The process runs from draft petition to submission, preliminary hearing for admissibility, detailed hearing and court order.
Landmark PILs include Hussainara Khatoon vs. State of Bihar, Vishaka vs. State of Rajasthan and M.C. Mehta vs. Union of India.
Court fees are minimal, around ₹50 in the Supreme Court and similar nominal fees in High Courts.

Overview

What is Public Interest Litigation?

Public Interest Litigation is an action that allows anyone, not only the directly affected party, to approach the court on behalf of the public on a matter of public interest, especially to protect the fundamental rights afforded under Part III of the Indian Constitution. The plaintiff is not required to have any direct personal interest in the case. If it affects the public good, a case can be brought, even where the issue is environmental damage, corruption or a human rights violation.

Objectives of PIL

Uphold fundamental rights guaranteed under Part III
Keep governance accountable and limit misuse of power
Support marginalised or vulnerable communities and social justice
Minimise environmental destruction and protect the public domain
Make the judiciary accessible to those who lack resources
