M. C. Mehta v. Union of India (Oleum Gas Leak Case), Supreme Court of India (1987)
M. C. Mehta v. Union of India (AIR 1987 SC 1086) created the groundbreaking doctrine of 'Absolute Liability' in environmental and tort jurisprudence. Moving beyond the traditional 19th-century English rule of from Rylands v. Fletcher, the Supreme Court ruled that hazardous and inherently dangerous industrial enterprises owe an absolute, non-delegable duty to the community, free from any statutory exceptions or defenses.
In December 1985, merely one year after the horrific Bhopal Gas Tragedy, a major leak of hazardous Oleum gas occurred from a unit of Shriram Foods and Fertilizers Complex in a densely populated area of West Delhi. The toxic leak killed an advocate and caused severe respiratory illnesses to hundreds of local residents. Public interest litigator M.C. Mehta filed a petition under seeking the permanent closure and relocation of the plant.
Absolute Liability and Right to Healthy Environment
Inspection reports by the Agarwal Committee and Manmohan Singh Committee, chemical composition logs of oleum gas, meteorological wind reports during the incident, and hospital emergency admission records.
Shriram Fertilizers argued that it had taken all reasonable safety precautions and should be entitled to common law exceptions (such as act of God, third-party intervention, or statutory authority) under Rylands v. Fletcher. The petitioner argued that enterprises engaging in ultra-hazardous activities must bear absolute liability for all harms caused, regardless of fault.
The Supreme Court formulated the Absolute Liability principle, ordering Shriram to pay compensation to all victims and post a deposit of ₹20 Lakhs with bank guarantees to resume operations under stringent safety supervision.
Chief Justice P.N. Bhagwati held that 19th-century English common law principles cannot constrain 20th-century Indian environmental law. An enterprise engaged in hazardous activity for commercial gain owes an absolute duty to the public; if harm occurs, the enterprise cannot plead lack of or invoke defenses.

** How liable are hazardous industries for harm? ###
India and the United States both have legal systems that hold industries accountable for environmental harm, but they approach liability very differently. M. C. Mehta (1987) established absolute liability in India, while the U.S. has a different approach. ###
** U.S. has strong environmental law tradition. **Why preferable to others:** UK, France, China, and Russia have different environmental traditions. **
Each system arrived at the same problem from a different direction: how to hold hazardous industries accountable for environmental disasters. In India, the Court had to decide whether with exceptions applied. In the U.S., courts use different liability frameworks. ###
| Topic | India | USA |
|---|---|---|
| Legal Issue | What liability standard for hazardous industries? | How is environmental liability determined? |
| Constitutional Basis | Article 21; absolute liability | Common law; CERCLA; strict liability |
| Leading Case | M. C. Mehta (Oleum Gas Leak) (1987) | Chevron U.S.A. Inc. v. Natural Resources Defense Council (1984) |
| Court's Reasoning | Absolute liability; no exceptions | Strict liability with exceptions |
| Outcome | Established absolute liability doctrine | Established environmental liability frameworks |
Both systems recognize that hazardous industries must be held accountable for environmental harm, and both courts have issued landmark rulings to define liability. In both countries, the judiciary has played a key role in advancing environmental protection. ###
The paths diverge in approach. In India, M. C. Mehta established "absolute liability" with no exceptions for hazardous industries, discarding common law defenses. The Indian approach is enterprise-focused and victim-protective. In the U.S., by contrast, courts apply strict liability with traditional exceptions (act of God, third-party sabotage), and statutory frameworks like CERCLA provide detailed liability rules. The U.S. approach is more rule-based and balanced. The result is a more victim-protective approach in India and a more balanced one in the U.S. ###
The takeaway for readers is that environmental liability is not just about compensation—it is about deterrence. In India, the absolute approach maximizes deterrence. In the U.S., the balanced approach provides predictability. For citizens, both systems provide environmental protection, but the Indian model is more claimant-friendly. ###
M. C. Mehta and U.S. environmental cases both gave judges the power to define liability, but they approached the problem differently. One protects victims; the other balances interests. Together, they show that liability is not just about fault—it is about responsibility. ***
