Narmada Bachao Andolan v. Union of India

A movement named for the river it was trying to save asked the Supreme Court to halt one of independent India's biggest dam projects. The Court split 2:1 and let construction continue — not because it dismissed the human and ecological cost, but because it decided that cost had to be met with resettlement, not with stopping the dam. The dissent thought otherwise, and the disagreement itself became part of what the case is taught for.

Parties

Narmada Bachao Andolan ("Save the Narmada Movement") — petitioner; a social movement representing communities displaced or affected by the Sardar Sarovar Dam project on the Narmada river.

Union of India and others — respondents; the central government and the states of Gujarat, Madhya Pradesh and Maharashtra, party to the Sardar Sarovar Project.

Facts

The Sardar Sarovar Project, a large multi-purpose dam on the Narmada river spanning Gujarat, Madhya Pradesh and Maharashtra, had been under construction and litigation for years by the time this petition reached the Supreme Court. The project promised substantial irrigation, drinking water and power benefits across the three states, but its construction, and the consequent submergence of land as the dam's height increased, displaced a very large number of people — predominantly tribal and rural communities in the submergence zone — raising serious concerns about whether adequate rehabilitation and resettlement of the displaced population, and adequate environmental safeguards, had been put in place before further construction proceeded.

Narmada Bachao Andolan, a movement formed to represent the interests of these displaced and affected communities, filed a writ petition seeking to halt further construction of the dam, arguing that the human displacement and environmental damage caused by the project outweighed its claimed benefits, and that rehabilitation of the displaced population had not kept pace with the submergence caused by the rising height of the dam.

Issues Raised

1. Should the Supreme Court order a halt to construction of the Sardar Sarovar Dam given the scale of displacement and environmental impact caused by the project?
2. Had adequate rehabilitation and resettlement measures been put in place for the population displaced by the project, and what should the Court do if resettlement had lagged behind construction?
3. How should the doctrine of sustainable development be applied where a project has genuine developmental value — irrigation, drinking water, power — but also causes significant displacement and environmental disruption?
4. What is the appropriate scope of judicial review of a policy decision, taken by the executive and reviewed by expert bodies over an extended period, to proceed with a major infrastructure project of this kind?

Arguments Contended

On behalf of Narmada Bachao Andolan (Petitioner): It was argued that the scale of displacement caused by the Sardar Sarovar Project, and the environmental disruption to the Narmada valley, were disproportionate to the project's claimed benefits, that rehabilitation and resettlement of displaced persons had not been completed or adequately secured before submergence occurred at each successive stage of the dam's construction, and that construction should be halted, or at minimum strictly conditioned, until proper rehabilitation could be guaranteed and a full environmental and social impact assessment completed.

On behalf of the Union of India and the party States (Respondents): It was argued that the Sardar Sarovar Project had been under study, planning and inter-state agreement for decades, including through the Narmada Water Disputes Tribunal, that it would bring substantial irrigation, drinking water and power benefits to a large population across three states, that rehabilitation and resettlement packages for displaced persons had been put in place and were required to be implemented in step with the dam's construction, and that halting a project of this scale and importance, after such extensive study and part-completion, would itself cause serious harm by depriving the intended beneficiaries of its benefits.

Court's Reasoning

The majority (A.S. Anand, C.J. and B.N. Kirpal, J.) held that the decision to construct a project of this scale and national importance, taken after extensive study, inter-state agreement, and continuous review by expert bodies over many years, was primarily a matter for the executive, and that the Court's role was not to second-guess the wisdom of undertaking the project but to ensure that displacement and environmental harm were properly addressed through adequate safeguards — applying the doctrine of sustainable development as a principle of reconciliation between developmental needs and environmental/human costs, rather than treating the two as always mutually exclusive. The majority held that construction could continue, but conditioned this on rehabilitation and resettlement of displaced persons being completed in step with the rising height of the dam, so that no further submergence would occur without the affected population first being properly resettled — treating continuous monitoring of rehabilitation, rather than a blanket halt to construction, as the appropriate judicial response.

Bharucha, J., dissenting, took the view that the scale of the project's human and environmental consequences, and the extent to which rehabilitation had already lagged behind construction at the stages completed so far, meant that relief could not properly be denied merely because construction had already progressed significantly and considerable delay and expenditure had already occurred; the dissent placed greater weight on the precautionary and environmental concerns raised by the petitioner and would have required fuller compliance before allowing further construction to proceed.

Judgement

By a 2:1 majority, the Supreme Court permitted continued construction of the Sardar Sarovar Dam, conditioning further increases in the dam's height on the completion of rehabilitation and resettlement of persons displaced at each stage, and directing continuous monitoring of compliance with rehabilitation obligations; Bharucha, J. dissented, favouring a stricter approach to displacement and environmental concerns before permitting further construction.

Legal Principle / Ratio

Where a large infrastructure project has genuine developmental value but also causes significant human displacement and environmental impact, courts may apply the doctrine of sustainable development to permit the project to proceed, conditioned on adequate, verified rehabilitation and resettlement of the displaced population kept in step with construction, rather than ordering an outright halt — judicial review of such policy decisions, taken by the executive after extensive expert study, is generally limited to ensuring adequate safeguards rather than substituting the Court's own assessment of the project's overall desirability.

Significance

Narmada Bachao Andolan v. Union of India is the leading Indian illustration of the doctrine of sustainable development being applied not to block a developmental project but to reconcile it with the human and environmental costs it imposes, through conditions rather than prohibition — a materially different judicial technique from cases like Vellore Citizens Welfare Forum, where the precautionary principle led to closure and remediation orders against polluting industries. The 2:1 split, and Bharucha, J.'s dissent, are frequently discussed as illustrating that "sustainable development" is a balancing standard capable of yielding different results depending on how a court weighs developmental benefit against displacement and ecological cost, rather than a mechanical formula with only one correct answer — a case is regularly cited both for its majority holding and to correct the common student error of describing it as a unanimous decision.

Exam-Important Points

• Facts in one line: Narmada Bachao Andolan sought to halt the Sardar Sarovar Dam on the Narmada, citing large-scale displacement and inadequate rehabilitation.
• Holding (2:1, Bharucha, J. dissenting): construction was permitted to continue, conditioned on rehabilitation/resettlement keeping pace with the dam's rising height.
• Key principle: applies sustainable development as a reconciliation tool (conditions, not prohibition) — contrast with Vellore Citizens, where the precautionary principle led to closure/remediation.
• Classic exam trap: this was not a unanimous decision — it was decided 2:1.
• Illustrates that "sustainable development" is a balancing standard, not a fixed formula — different judges can weigh development against displacement differently on the same facts.
