M.C. Mehta v. Union of India is a landmark judgment of the Supreme Court of India that significantly shaped Indian environmental jurisprudence. The case raised crucial questions relating to the liability of hazardous industries, industrial safety, and the use of Public Interest Litigation (PIL) to safeguard the rights of citizens. This article analyses the facts, issues, and judicial reasoning involved in the case. The Supreme Court rejected the traditional rule of strict liability laid down in Rylands v. Fletcher and instead evolved the doctrine of absolute liability for enterprises engaged in hazardous activities. This decision played a transformative role in balancing industrial development with public safety and environmental protection in India.

Introduction

The decision in M.C. Mehta v. Union of India emerged from growing concerns over the safety of hazardous industries functioning in densely populated urban areas. The case arose from a petition filed by environmental activist M.C. Mehta following the oleum gas leak from the Shriram Food and Fertilizer Industries plant in Delhi, which caused death and injury to nearby residents.

The Supreme Court examined the accountability of such industries and laid down the principle of absolute liability, thereby strengthening environmental protection and industrial liability in India.

Facts

Shriram Food and Fertilizers Industries, a subsidiary of Delhi Cloth Mills Ltd., operated multiple industrial units in a densely populated area of Delhi. The units manufactured hazardous chemicals such as caustic soda, chlorine, hydrochloric acid, sulphuric acid, alum, and sodium sulphate.

Following the Bhopal Gas Tragedy (1984), concerns over industrial safety intensified. A firm named “Technica” was engaged to assess the safety of the caustic chlorine plant. In March 1985, parliamentary concern over potential gas leaks led to the appointment of the Manmohan Singh Committee to inspect the plant and suggest safety measures.

Environmental lawyer M.C. Mehta filed a petition before the Supreme Court under Article 32 of the Constitution, seeking permanent closure of Shriram’s industrial units on grounds of public health and environmental risk.

While the petition was pending, on 4 December 1985, oleum gas leaked from one of the units, causing death and injury to several people. A second minor leak occurred on 6 December 1985.

Taking cognizance of the incident, the Supreme Court expanded its inquiry. Initially before a three-judge bench, the matter was later referred to a five-judge Constitution Bench due to its constitutional significance.

Issues

Whether the Supreme Court can intervene in public interest under Article 32 to protect citizens from industrial hazards.
Whether hazardous industries such as Shriram should be permitted to operate in densely populated areas, and if so, under what conditions.
Whether the principle of strict liability established in Rylands v. Fletcher is applicable in the Indian context.

Judgment

The Supreme Court held that Article 32 not only empowers the Court to issue orders for enforcement of fundamental rights but also imposes a duty upon the Court to protect such rights. For this purpose, the Court possesses all incidental and ancillary powers, including the power to fashion new remedies.

On the question of industrial operation, Justice P.N. Bhagwati observed that the closure of hazardous industries would negatively impact economic growth and employment. Therefore, Shriram was allowed to continue operating on an interim basis, subject to 11 mandatory safety conditions, including:

Establishment of a safety committee for employees,
Training of workers in plant safety,
Appointment of inspectors to assess pollution levels,
Compliance monitoring by expert committees.

Most importantly, the Court formulated the doctrine of absolute liability, rejecting Rylands v. Fletcher and holding that:

Enterprises engaged in inherently hazardous or dangerous activities owe an absolute and non-delegable duty to ensure no harm results to anyone. If harm occurs, they are absolutely liable to compensate affected persons, without exceptions or defenses.

This liability is stricter than strict liability, as it excludes exceptions such as acts of God or third-party interference.

Analysis

Through this judgment, the Supreme Court sought to balance industrial development with public safety and environmental welfare. Instead of shutting down the industry, it imposed stringent safety obligations and expert oversight.

The principle of absolute liability strengthened environmental governance in India by ensuring that hazardous industries cannot escape liability by claiming due care or absence of negligence. This established a victim-centric compensation regime and incentivized industries to adopt higher safety standards.

Conclusion

M.C. Mehta v. Union of India constitutes a pivotal moment in Indian environmental jurisprudence. By articulating the doctrine of absolute liability and expanding the scope of Article 32, the Supreme Court enhanced environmental protection, public safety, and judicial oversight. The case continues to influence regulatory policies concerning hazardous industries and remains foundational to modern environmental law in India.
