Environmental Law

Vellore Citizens' Welfare Forum v. Union of India

(1996) 5 SCC 647

Facts

Hundreds of tanneries in Tamil Nadu discharged untreated effluent containing toxic chemicals.
The pollution entered:
the River Palar;
agricultural land;
wells;
groundwater.
Water became unsuitable for drinking and cultivation.
Farmers and residents suffered:
crop loss;
declining soil quality;
health risks;
damage to livelihood.
Many tanneries failed to establish adequate treatment plants despite repeated opportunities.
The petitioners sought closure, compensation and environmental restoration.

Whether the tanneries could continue operating without adequate effluent treatment.
Whether the precautionary principle and polluter-pays principle formed part of Indian law.
Who should bear the cost of compensation and ecological restoration.

Sustainable development is part of Indian environmental jurisprudence.
The precautionary principle requires:
anticipation and prevention of environmental harm;
action despite lack of complete scientific certainty;
the developer to show that the activity is environmentally safe.
Polluter pays means that the polluter must bear:
compensation to victims;
the cost of restoring damaged ecology.
Articles 21, 47, 48A and 51A(g) support these principles.
The Environment Protection Act gives the Central Government power to create an authority for enforcement.

The Court accepted that the leather industry:
generated employment;
earned foreign exchange;
contributed to the economy.
Sustainable development did not require the automatic elimination of industry.
It required industry to operate within ecological limits.
The tanneries could not treat rivers and groundwater as free waste-disposal systems.
Treatment cost was part of the lawful cost of production.
The Court rejected the argument that environmental standards should wait until the exact injury to each person was proved.
Toxic effluent had already produced extensive contamination.
Preventive action was therefore required.
The polluter-pays principle extended beyond a fine.
Restoration had to include:
cleaning water sources;
rehabilitating land;
compensating affected families;
monitoring future discharge.
Non-compliant tanneries were required to close.
Those capable of establishing treatment could continue only after satisfying the Pollution Control Board.
The Court also recognised the need for a specialised authority to identify victims, assess ecological damage and recover costs from the polluters.
This converted broad environmental principles into an enforceable institutional remedy.

The Supreme Court declared the precautionary principle, polluter pays and sustainable development to be part of Indian law.
Non-compliant tanneries were directed to close.
Each tannery was required to contribute to an environmental-protection fund.
An authority under Section 3(3) of the Environment Protection Act was to:
assess damage;
identify affected persons;
award compensation;
determine restoration costs.
The industries, not the public, had to finance remediation.
The case is a foundational source of modern Indian environmental principles.
Use this case for: constitutional and statutory recognition of precaution, polluter pays and sustainable development.
