Environmental law affirms precautionary and polluter pays principles while requiring polluting industries to convert or relocate.

Industrial emissions in the Taj Trapezium Zone were found to be a major source of air pollution harming the Taj Mahal and local residents, and industries using coke or coal were required to convert to natural gas or relocate outside the zone, with closure for non-compliance. The judgment also affirmed that environmental protection must proceed on a sustainable development basis, with preventive action where serious harm is threatened. It held that the precautionary principle and the polluter pays principle form part of Indian environmental law, placing the burden on industry to show environmental safety and requiring polluters to fund compensation as well as restoration of damaged environment.

Issues: (i) whether the industries operating in the Taj Trapezium Zone were contributing to air pollution and should be required to shift to natural gas or relocate outside the zone; (ii) whether the precautionary principle and the polluter pays principle form part of the environmental law of the country.

Issue (i): whether the industries operating in the Taj Trapezium Zone were contributing to air pollution and should be required to shift to natural gas or relocate outside the zone.

Analysis: On the basis of the expert reports placed on record, the ambient air around the Taj Mahal was found to be polluted primarily by industrial emissions, particularly from coke and coal-based operations. The reports also showed that the pollution had damaging effects on the Taj Mahal and on the people living in the area. The Court held that environmental protection had to be harmonised with industrial development and that sustainable development required reduction of pollution at source. It further held that industries which could obtain gas connections should convert to natural gas, while those unable or unwilling to do so must stop operating with coke or coal and relocate outside the Taj Trapezium Zone.

Conclusion: The issue was decided in favour of the petitioner. The 292 listed industries were directed to shift to natural gas or relocate, and failing compliance they were to be closed.

Issue (ii): whether the precautionary principle and the polluter pays principle form part of the environmental law of the country.

Analysis: The judgment relied on the constitutional mandate to protect life and improve the environment, together with the statutory framework for pollution control, to hold that environmental measures must anticipate, prevent and attack the causes of environmental degradation. It also held that where there are threats of serious or irreversible harm, lack of scientific certainty cannot justify postponing preventive action, and that the burden lies on the industry to show that its activity is environmentally benign. The judgment further accepted that a polluter is liable not only to compensate victims but also to bear the cost of restoring the damaged environment.

Conclusion: The precautionary principle and the polluter pays principle were held to be part of the environmental law of the country.

Final Conclusion: The judgment imposed enforceable environmental obligations on the polluting industries in the Taj Trapezium Zone, prioritising pollution control through fuel conversion or relocation and affirming core principles of environmental jurisprudence.

Ratio Decidendi: Where industrial activity causes serious environmental harm, preventive environmental protection prevails, the burden is on the industry to show environmental safety, and the polluter must bear the cost of both compensation and restoration.
