Ordinarily, only a person whose own legal right has been violated can approach a court for a remedy — a rule called 'locus standi'. Public interest litigation relaxes that rule: it lets a person or organisation approach a constitutional court on behalf of a class of people, often the poor or otherwise disadvantaged, who face practical barriers to approaching a court themselves.
Where the flexibility comes from
PIL developed through Supreme Court practice from the late 1970s onward, using the Court's writ jurisdiction under Articles 32 and 226 in an expansive way — accepting petitions filed as simple letters, waiving strict procedural formality, and appointing commissions to gather facts directly rather than relying solely on adversarial submissions from represented parties. None of this required a new statute; it developed as an interpretation of how the existing constitutional writ jurisdiction could be used.
What PIL has actually been used for
- Prison and undertrial conditions — cases brought on behalf of detained people unable to petition courts themselves.
- Environmental protection — cases addressing pollution or ecological harm affecting communities without the resources to litigate individually.
- Bonded labour and child labour — cases brought on behalf of workers in situations that made direct access to courts practically impossible.
- Government accountability — cases seeking to compel the state to fulfil statutory or constitutional obligations it was neglecting.
Where it draws criticism
The same flexibility that makes PIL powerful for genuine public interest claims also makes it usable for publicity-seeking litigation, or for parties pursuing what is really a private commercial dispute dressed up in public interest language. Courts have responded by developing filters — costs imposed on frivolous PIL petitions, closer scrutiny of the petitioner's actual standing and motive — without abandoning the tool itself.
The result is a genuinely two-sided tool: still the mechanism through which some of India's most significant rights litigation has reached the courts, and still, at the same time, a jurisdiction courts have had to actively guard against being used for purposes it was never meant to serve.
