Public Interest Litigation, Its Founding Promise, Its Present Drift, and the Case for Discipline

Public interest litigation occupies an unusual place in Indian constitutional history: it is a judicial invention rather than a legislative creation, born not from a statute but from a deliberate choice by a generation of Supreme Court judges, most prominently Justices P.N. Bhagwati and V.R. Krishna Iyer, to relax the traditional requirement that only a person with a direct personal stake in a matter could approach a court for relief. In the years following the Emergency, when the judiciary was acutely conscious of its own earlier failures to protect civil liberties, this relaxation of locus standi was framed as a corrective, a way of ensuring that prisoners, bonded labourers, pavement dwellers and others without the resources or literacy to navigate formal legal process could still have their grievances heard, provided someone acting in good faith brought their situation before the Court.

The founding cases and what they achieved

The early PIL docket produced results that are difficult to argue with on their merits. Hussainara Khatoon's litigation on undertrial prisoners, Bandhua Mukti Morcha's case on bonded labour, and the Supreme Court's interventions on custodial violence and prison conditions all emerged through this relaxed standing doctrine, often initiated through nothing more formal than a letter addressed to a judge, which courts began treating as a writ petition in its own right under what became known as epistolary jurisdiction. Environmental jurisprudence in India owes an enormous debt to PIL as well; the Ganga pollution cases and the vehicular pollution litigation in Delhi, both driven by public-spirited petitioners rather than directly affected private parties, produced binding directions that reshaped industrial regulation and urban transport policy in ways ordinary adversarial litigation, dependent on an aggrieved party with standing and resources, would have been far slower to achieve.

Where the tool began attracting the wrong users

Success, however, changed the incentives surrounding PIL considerably. As the device proved capable of generating rapid judicial attention, media coverage and, on occasion, genuine policy change, it began attracting petitioners whose motivations bore little resemblance to the original conception of representing the voiceless. Business rivals began filing PILs against competitors under the guise of public concern, seeking to stall a rival project through litigation delay rather than through the slower channels of a private commercial dispute. Politically motivated PILs, timed to embarrass an opposing party or to seek judicial intervention into what were essentially electoral or policy disagreements better resolved through the ballot or through Parliament, became a recurring feature of the docket. The Supreme Court itself acknowledged this drift explicitly, with several benches over the years criticising what they termed publicity interest litigation or personal interest litigation dressed up in public language, and imposing costs on petitioners found to have filed frivolous or motivated PILs.

The problem of courts legislating through directions

A related concern, distinct from petitioner motive, involves what courts do once a PIL is admitted. Some PIL-driven directions have ventured deep into matters of policy detail, specifying implementation mechanisms, monitoring committees and timelines that arguably belong to the domain of the executive rather than the judiciary, raising separation of powers concerns even among commentators otherwise sympathetic to the underlying cause. The vehicular pollution and forest conservation cases, for instance, produced continuing mandamus orders under which the Supreme Court retained ongoing supervisory jurisdiction over policy implementation for years, effectively functioning as a standing regulatory body. Defenders of this approach argue that such sustained judicial supervision became necessary only because the executive had failed repeatedly to act on its own obligations, and that abdication by one branch cannot be met with abdication by another. This is a genuinely strong counter-argument, since several of the most significant PIL-driven reforms occurred precisely because ordinary bureaucratic and political processes had stalled for years despite clear legal obligations, and it would be too simple to conclude that judicial restraint alone would have produced a better outcome in those cases.

Screening without shutting the door

The answer to PIL's misuse is not to dismantle the relaxed standing doctrine that gave the device its purpose, but to strengthen the screening mechanisms courts apply at admission. Some High Courts have begun requiring petitioners to disclose any personal, financial or commercial interest connected to the matter at the outset, along with an affidavit affirming the bona fide public interest character of the petition, with false disclosure inviting exemplary costs. The Supreme Court has occasionally imposed heavy costs on petitioners found to have filed motivated PILs, though such orders remain inconsistent across benches and rarely function as a serious deterrent given the relatively modest sums typically involved compared to the strategic value a litigant may extract from prolonged delay. A more systematic filtering process at admission, distinguishing between petitions raising genuine, unrepresented public grievances and those functioning as proxies for private commercial or political disputes, would preserve PIL's original utility while curbing its more cynical uses.

Preserving an imperfect but valuable innovation

It is worth remembering that PIL remains, on balance, one of the more genuinely democratising innovations in Indian constitutional practice, a rare instance in which the judiciary expanded access to justice for those structurally least able to demand it themselves. The drift toward misuse is real and deserves serious institutional attention, but the appropriate response is calibration rather than retreat. A doctrine built to give voice to the voiceless should not be dismantled because some litigants learned to borrow its language for other purposes; it should instead be defended by courts willing to distinguish, case by case and with rigour, between the petitions that honour its founding purpose and those that merely exploit its name.
