Absolute Liability for CLAT: MC Mehta and Oleum Gas

📑 On this page

⚡ The short answer

Absolute liability is India's rule for hazardous or inherently dangerous industries. If harm results from such an activity, the enterprise must compensate everyone affected, with no proof of fault and no exceptions: not act of God, not sabotage, not "we took all care". The Supreme Court created it in the Oleum gas case to go beyond Rylands v Fletcher.

🎬 The 30-second story

The cloudburst at Kabir Agro-Chem

“Three audits, zero lapses. Safest plant around!”

🏭

Kabir

Kabir's pesticide plant sits beside Rohan's farm and Meher's school.

“That's not rain, that's a wall of water!”

⛈️

Rohan

A freak cloudburst floods the yard. Chemical drums split.

“Why does the well water smell weird?”

🤢

Meher

Toxic runoff reaches the school well. Children fall ill.

“Act of God! I did everything right.”

⚖️

Kabir

Sued, Kabir reaches for old defences.

Tara's ruling: Kabir pays in full. He ran a hazardous activity and harm came from it, so under absolute liability neither the storm nor his audits help. Under the old English rule, act of God might have saved him.

What is absolute liability?

Most torts ask: was the defendant careless? Absolute liability skips that question. Run a dangerous business for profit and you guarantee the safety of everyone around it. Something goes wrong, you pay.

🧮 The formula

☣️

Hazardous activity

Harm to anyone

💸

Absolute liability

no fault, no defence

A passage will say: "An enterprise engaged in a hazardous activity owes an absolute duty that no harm results to anyone; reasonable care is no answer." Two facts decide most questions: is the activity hazardous, and did the harm flow from it?

✓Profit means price. A hazardous business is tolerated only if it absorbs the cost of its accidents as an overhead.
✓Only the enterprise sees the danger. It alone can discover, guard against and warn of hazards.
✓Victims can't prove fault. A villager can't show which valve failed. So the law stops asking.

📌 What CLAT actually expects

The passage states the rule, often beside strict liability and polluter pays. You sort the facts: hazardous or not, which defence is pleaded, and does the rule allow it?

Why did India need a stricter rule than Rylands v Fletcher?

England's 1868 rule already imposed no-fault liability for dangerous things that escaped, but with exits: act of God, a stranger's act, the victim's default, consent, statutory authority. After two deadly gas leaks in two years, the Supreme Court decided a rule built for a burst reservoir couldn't police a chemical plant.

Where are the edges of absolute liability?

What counts as a hazardous activity?

The Court meant industries that threaten workers and neighbours: toxic gas, corrosive chemicals, explosives, hazardous waste. A bakery or tuition centre isn't one. CLAT 2020 (Q80) turned on exactly this.

Do workers inside the plant count?

Yes. Rylands needs an escape, which is why the worker in Read v Lyons lost. Absolute liability protects "anyone" harmed, and the Court named factory workers. No boundary-wall test.

Contractors don't shift it. The duty is non-delegable.
Care and knowledge are irrelevant. "We took every precaution" is no answer.
Public or private, the enterprise pays.

Why does a richer company pay more?

MC Mehta said compensation must match the magnitude and capacity of the enterprise, so it deters: the bigger the firm, the bigger the bill. In 1991 the Court refused to use this to reopen the Bhopal settlement.

Does it cover the land, the water and the air?

Yes. The Bichhri case paired absolute liability with polluter pays: compensate the people and restore soil and water. In 2025 the Court added that the liability continues while pollution remains.

ℹ️ Is the rule even binding? An honest footnote

MC Mehta awarded no compensation itself. In the 1991 Bhopal review one judge called the rule obiter; the 1996 Bichhri bench disagreed and applied it as binding. Treat it as settled.

⚠️ The passage beats your memory

If a passage keeps a defence, apply it: CLAT 2020 Q78 had the company escape strict liability for an earthquake yet stay absolutely liable. Untested extremes (a thief who gasses himself) also turn on the passage.

Which cases built absolute liability?

🧪

Landmark case · 1986 · Supreme Court, five judges

MC Mehta v Union of India (Oleum Gas Leak)

📋

What happened

In December 1985 oleum gas leaked from a Shriram chemical unit in crowded Delhi, a year after Bhopal. Victims sought compensation.

❓

The question

Is a hazardous industry's liability limited by the Rylands exceptions?

🔨

What the court held

No. A hazardous enterprise owes an absolute and non-delegable duty to compensate all affected, with no Rylands exception and no plea of care.

What CLAT takes from it: India builds its own tort law. Hazardous activity plus harm equals liability.

🏜️

Landmark case · 1996 · Supreme Court

Indian Council for Enviro-Legal Action v Union of India

📋

What happened

Chemical units in Bichhri village, Rajasthan, dumped toxic sludge for years, poisoning wells and farmland.

❓

The question

Must these "rogue industries" pay, including for the clean-up?

🔨

What the court held

Yes. Following the Oleum case they were absolutely liable, and under polluter pays had to fund restoring the soil and groundwater.

What CLAT takes from it: It reaches slow pollution too, and the bill includes repairing nature.

How has CLAT asked absolute liability?

📝 Asked in CLAT 2020 · Q78 Three principles, one disaster

On 7th May 2020, a major leakage of Styrene gas was reported from the plastics-manufacturing plant 'LG Polymers'… styrene gas… is a 'hazardous chemical'… Principle 1: Polluter Pays. … the person who damages or destructs the environment has the absolute obligation to bear the cost of ameliorating the environment… Principle 2: Strict Liability. … restricts liability when the escape is due to an act of strangers, Act of God, for example a natural calamity; due to the person injured or… with the consent of the person injured or with statutory authority. Principle 3: Absolute Liability. … a stringent form of Strict Liability as it is devoid of any exceptions…

A company ABC limited operates an industrial chemical plant… Due to an earthquake…, the valves of the reactors in the plant get damaged… resulting in the gas leakage. The gas leakage resulted in the death of 12 workers of the plant and also some people living nearby the Plant. In this situation, in order to decipher the liability of ABC Limited, choose the best option:

AABC Limited can be held liable under the principles of Strict and Absolute Liability and Polluter pays principle as well.

BABC Limited can be held liable under the Polluter Pays Principle and the Principle of Absolute Liability, but can be exempted under the rule of Strict Liability.

CABC Limited will not be held liable under any of the Principles.

DABC Limited will be held liable under Strict and Absolute Liability principles but the Principle of "Polluter Pays" will not be applicable to this situation.

Reveal answer + reasoning

Answer: B

Test each principle. An earthquake is a natural calamity, a listed act of God exception to strict liability, so ABC escapes that one. Absolute liability has no exceptions, and polluter pays applies whatever the cause. B.

Why the others fail

A — Ignores strict liability's act-of-God exception.
C — Absolute liability and polluter pays have no earthquake exit.
D — Backwards: strict liability is the one that falls away.

📝 Asked in CLAT 2020 · Q79 Ignorance is no excuse

Same LG Polymers passage as above.

The argument of LG Polymers that, they did not know that the Styrene Gas could leak:

Ais a strong argument and can reduce their liability under the Polluter Pays Principle.

Bis a strong argument and can reduce their liability under the Strict Liability Principle.

Cis a weak argument and will not help in reducing the liability of LG Polymers under any of the principles.

Dis a weak argument but may help in reducing their liability under the Strict Liability Principle.

Reveal answer + reasoning

Answer: C

No principle asks what the company knew. Absolute liability rejects even "we took all precautions"; ignorance isn't among strict liability's listed exceptions; polluter pays looks only at who caused the damage. C.

Why the others fail

A — Polluter pays turns on causing damage, not knowledge.
B — Ignorance isn't a listed exception.
D — Same flaw.

📝 Asked in CLAT 2018 · Q196 Escape in any manner

Legal Principle: A person who keeps hazardous substances in his premises, is responsible for the fault if that substance escapes in any manner and causes damage. Facts: A, an industrialist stored 1000 litres of liquid ammonia in a tank in his premises for his industrial use. There was a leakage from the tank due to which there was ammonia vapour in the surroundings. Many workers in other industries as well as his own industry and some members from the public suffered serious health hazards.

Examine the liability of A, if any.

AA may be liable for the injury sustained by his workers only and not others.

BA is liable as he is responsible for the injury caused by the leakage of ammonia from his premises.

CA is not liable because there was no fault on his part for the escape of the dangerous substance.

DA is not liable because he did not expect a leakage from the tank.

Reveal answer + reasoning

Answer: B

Every trigger is met: hazardous substance, kept on premises, escapes in any manner, causes damage. "Responsible for the fault" means for the harm; carelessness isn't asked. It protects his workers and the public alike. (The key gives option 2.)

Why the others fail

A — Nothing limits it to his own workers.
C — "In any manner" covers a blameless leak.
D — Foresight is irrelevant.

Also asked from the 2020 passage: Q76 (liable under all three principles), Q77 (polluter pays covers restoration and compensation) and Q80 (liability depends on whether the gas was hazardous).

Frequently asked questions

What is absolute liability in simple words?

An enterprise running a hazardous or inherently dangerous activity must compensate anyone harmed by it, careless or not, whatever caused the accident. Act of God, sabotage or every precaution taken is no defence. The Supreme Court created the rule in the Oleum gas leak case.

What is the difference between strict and absolute liability?

Both impose liability without fault. Strict liability (Rylands v Fletcher) needs a dangerous thing to escape and allows defences like act of God. Absolute liability covers hazardous enterprises, needs no escape, allows no defence and scales damages to the firm's size.

Was absolute liability applied in the Bhopal gas tragedy?

Not directly. Bhopal happened in December 1984; the rule came from the Oleum gas case in December 1986. Bhopal's claims were settled in 1989 for US$470 million, so no court applied the rule to Union Carbide in a final verdict, though Bhopal pushed the Court towards it.

Does absolute liability apply to every business?

No. Only enterprises carrying on hazardous or inherently dangerous activities, like toxic chemicals, gas storage, explosives or hazardous waste. A shop, school or office faces ordinary negligence rules. In CLAT, first check whether the facts show a hazardous activity.

Is absolute liability the same as polluter pays?

Close cousins, not twins. Absolute liability makes a hazardous enterprise compensate those its accidents harm. Polluter pays makes whoever damages the environment compensate victims and restore it. The Bichhri case applied both; CLAT 2020 asked them side by side.
