In Re Illegal Sand Mining in the National Chambal Sanctuary: environmental protection as a continuing constitutional obligation

In Re: Illegal Sand Mining in the National Chambal Sanctuary and Threat to Endangered Aquatic Wildlife is a suo motu proceeding before the Supreme Court of India concerning the riverine stretch of the Chambal that runs along the borders of Madhya Pradesh, Uttar Pradesh and Rajasthan. In an order published on 5 June 2026, a Division Bench of Justices Vikram Nath and Sandeep Mehta declined to treat the matter as a one-off grievance to be disposed of and instead recast it as a register of continuing constitutional obligation — a register the three States are bound to operate whether or not the Court is watching.

The order is the latest in an ongoing line. An earlier order in the same matter is reported as 2026 INSC 549 (also carried as 2026 LiveLaw (SC) 386); the directions discussed here are those in the May–June 2026 order, decided 26 May 2026 and published 5 June 2026. The proceeding remains live, listed for further hearing on 22 July 2026.

Background

The National Chambal Sanctuary is a protected riverine corridor that supports some of the subcontinent's most endangered aquatic species. The suo motu jurisdiction was engaged because the threat to that corridor was not abating: illegal sand mining along vulnerable stretches of the sanctuary had continued despite the protected status of the river and earlier rounds of judicial attention. The three riparian States — Madhya Pradesh, Uttar Pradesh and Rajasthan — share the river and, between them, the responsibility for policing extraction from it.

The pattern that drew the Court's censure was a familiar one in environmental litigation: the States had been responsive to the proceeding on paper without being responsive to the problem on the ground. They had filed affidavits; what they had not done was act. The Bench's response was to refuse to let the affidavit stand in for enforcement. It framed environmental protection as a "continuing constitutional obligation" under Articles 21, 48-A and 51-A(g) — the right to life and a wholesome environment, the directive to the State to protect and improve the environment, and the fundamental duty of every citizen to do the same — and held that "environmental governance cannot be reduced to a reactive exercise undertaken only after repeated judicial intervention." In substance, the Bench told the States to stop filing affidavits and start acting.

The constitutional framing matters because of what it does to the burden. If protection of the sanctuary is a continuing obligation, then compliance is not measured by whether a State has answered the Court's last query, but by whether the State is, as a standing matter, enforcing the law against those who mine the river illegally. That reframing is the doctrinal core of the order; the operative directions that follow are instruments for making the continuing obligation concrete and auditable.

The directions

The Bench issued a connected set of directions addressed to the three States and to the central authorities responsible for the river's flows.

Fast-tracked enforcement and frontline staffing. The States were directed to fast-track enforcement against illegal sand mining and, as far as practicable within one year, to fill Forest Guard and other frontline enforcement vacancies. The direction recognises a structural cause of under-enforcement: a sanctuary cannot be patrolled by an under-staffed cadre, and vacancies in the frontline are vacancies in the enforcement itself.

Surveillance infrastructure. Within roughly six months, the States were to install CCTV and night-vision surveillance across vulnerable stretches of the sanctuary, including near the NH-44 Morena–Dholpur bridge — a crossing identified as a pressure point for the movement of illegally mined sand. Night-vision capability matters because illegal extraction characteristically migrates to hours when patrolling is thin.

Interception, seizure and confiscation. The Bench directed immediate interception, seizure and confiscation of unregistered vehicles, vehicles bearing fake or tampered number plates, and machinery used in illegal mining or transport, together with prosecution of the owners and financiers behind the operations — not merely the drivers at the wheel. The States were further directed to maintain digital record-keeping of seizures and cases, so that enforcement leaves an auditable trail rather than evaporating into untraceable local action.

Environmental flows. Acting on concerns raised by the Central Empowered Committee about declining lean-season discharge and the preservation of environmental flows in the Chambal, the Bench impleaded the Ministry of Jal Shakti and the Central Water Commission and directed them to file affidavits on flow-preservation measures. This extends the proceeding beyond the conduct of miners to the hydrology of the river itself.

Compliance reporting. Finally, the Bench directed bimonthly compliance reports from the Chief Secretaries of the three States and listed the matter for 22 July 2026 — fixing accountability at the apex of each State administration and setting a return date against which performance can be measured.

Analysis: environmental flows and the species at stake

The directions divide into two registers. One targets the conduct of illegal mining — staffing, surveillance, seizure, prosecution. The other targets the condition of the river — its environmental flows. The second is the more doctrinally interesting, because it connects the sand on the riverbed to the water that moves over it and the species that depend on both.

The Central Empowered Committee's concern, as recorded by the Bench, was the declining lean-season discharge in the Chambal. Lean-season flow is the water that remains in the river during the dry months, when discharge is at its lowest; it is precisely the period during which aquatic habitat is most fragile and during which the riverbed is most exposed to extraction. The three endangered riverine species the Court identified — gharials, freshwater (Gangetic) dolphins and turtles — are each tied to the integrity of that flow regime. Gharials nest on sandbanks and basking sites that illegal extraction physically removes; freshwater dolphins, which navigate by echolocation in turbid water, depend on adequate channel depth and continuity that falling discharge erodes; and the sanctuary's turtle populations occupy the same nesting and basking substrate that sand mining strips away. Habitat loss from extraction and hydrological loss from declining discharge are, for these species, two faces of a single threat.

By impleading the Ministry of Jal Shakti and the Central Water Commission, the Bench placed responsibility for environmental flows where the levers actually sit — with the central agencies that govern water allocation and river management — rather than confining the proceeding to the policing of miners by State forest departments. The move recognises that protecting the gharial is not only a question of catching the people who take the sand; it is also a question of keeping enough water in the river. That is the practical content of treating environmental protection as a continuing obligation under Article 48-A: it requires the State machinery, at both tiers, to manage the resource on an ongoing basis rather than respond, episode by episode, to whatever the Court happens to ask next.

The conduct-register directions support the same logic. Targeting the owners and financiers — not just the drivers — addresses the economics that drive extraction; digital record-keeping of seizures converts enforcement into an auditable dataset; and the one-year window to fill frontline vacancies acknowledges that a protected area is only as protected as the cadre charged with patrolling it. Each direction is an instrument for making the continuing obligation measurable, and for ensuring that the next compliance report describes action taken rather than affidavits filed.

Why it matters

The order's significance lies less in any single direction than in the standard it sets for environmental compliance. By holding that environmental governance "cannot be reduced to a reactive exercise undertaken only after repeated judicial intervention," the Bench articulated a benchmark that travels well beyond the Chambal: a State discharges its constitutional environmental duty by enforcing the law as a standing matter, not by demonstrating responsiveness to the Court's most recent prompt. The continuing-obligation framing under Articles 21, 48-A and 51-A(g) shifts the question a court asks in this kind of proceeding — from "has the State answered us?" to "is the State, as a matter of course, doing what the law requires?"

The accountability architecture reinforces the point. Bimonthly reports from the Chief Secretaries, a one-year vacancy-filling timeline, a six-month surveillance deadline and a fixed return date together convert an abstract duty into a calendar with named officers attached to it. The impleadment of the Ministry of Jal Shakti and the Central Water Commission widens the frame from the criminality of extraction to the hydrology of the habitat, locating the survival of the gharial, the dolphin and the turtle in the management of the river's flows as much as in the policing of its banks.

For practitioners in environmental and wildlife litigation, the order marks how the Court is prepared to treat affidavit-driven "compliance" not matched by enforcement on the ground — and its willingness to attach the obligation, by name and by date, to the officials best placed to discharge it.
