Definition
Litigation filed in the High Court or Supreme Court by any person in the public interest, to protect constitutional rights of those unable to approach courts themselves, or to compel public authorities to perform their duties.
PIL is a distinctive judicial innovation developed by the Indian Supreme Court, notably through Justices P.N. Bhagwati and V.R. Krishna Iyer in the 1970s-80s. It radically relaxes the traditional rule of locus standi (only the aggrieved person can file) — any member of the public or organisation may file a PIL in the High Court (Article 226) or Supreme Court (Article 32) for enforcement of fundamental rights or other constitutional obligations of State authorities. PIL has been used to address bonded labour, environmental pollution, judicial appointments, custodial violence, access to food, and electoral reforms.
Statutory Definition
No specific statute — PIL is a judicial creation under Articles 32 and 226 of the Constitution, developed through Supreme Court rulings starting with S.P. Gupta v. Union of India AIR 1982 SC 149 (Judges' Transfer Case) and Hussein Ara Khatoon v. State of Bihar AIR 1979 SC 1360 (undertrial prisoners).
Etymology & Origin
Borrowed from American legal activism (US 'public interest law' movement of the 1960s), but transformed in India into a constitutionally grounded judicial tool. The Indian PIL is more expansive than the US version — courts here are willing to monitor compliance, not just adjudicate.

PIL: Courts as Guardians of Public Rights
Public Interest Litigation is perhaps the most distinctive and controversial development in Indian constitutional law. It transformed courts from passive arbiters of private disputes into active guardians of constitutional rights for those who cannot access the judicial system themselves — the poor, the marginalised, the voiceless. At its best, PIL has produced landmark reforms; at its worst, it has been misused for private ends under public-interest clothing.
Foundational Cases
- Hussein Ara Khatoon v. State of Bihar AIR 1979 SC 1360 — The Court treated a newspaper article about undertrial prisoners as a petition and directed their release. This established epistolary jurisdiction — letters and newspaper reports could trigger Supreme Court action.
- S.P. Gupta v. Union of India AIR 1982 SC 149 — Judges' Transfer case: the Court held that any member of the public could challenge unconstitutional executive action if there was public injury, not just the directly aggrieved person. This is the formal birth of PIL's locus standi doctrine.
- M.C. Mehta v. Union of India — series of cases on environmental protection (Ganga pollution, Delhi vehicular pollution, Taj Mahal protection) where the Court issued detailed directions to governments, creating what scholars call 'judicial legislation.'
Legitimate vs. Abusive PIL
The Supreme Court has become increasingly critical of what it calls 'publicity interest litigation' or 'private interest litigation' — PILs filed for commercial or personal advantage dressed up as public interest. In Balwant Singh Chaufal v. State of Uttarakhand (2010) 3 SCC 402, the Court held that PIL petitions found to be for private gain should be dismissed with costs. Courts now require petitioners to disclose their interest and credentials.
PIL and Separation of Powers
Critics argue that PIL has blurred the line between judicial and executive functions — courts monitoring schemes, setting timelines for departments, and issuing detailed directions encroach on executive domains. Defenders argue that PILs only fill the vacuum left by executive failure. The Supreme Court has itself oscillated — sometimes expanding PIL jurisdiction, sometimes contracting it in deference to the separation of powers principle.
“Public Interest Litigation is a potent weapon in the armoury of law for combating oppression and injustice. Its misuse for private or political ends corrodes this weapon and diminishes public trust in judicial institutions.”
