Strict Liability & Absolute Liability
Liability for harm from dangerous things and hazardous industry, with or without exceptions
In one minute
Strict and absolute liability make a person pay for harm from a dangerous thing or activity, even if they took care. The victim does not have to prove fault.
Strict liability comes from Rylands v. Fletcher (1868) and has exceptions. Absolute liability comes from M.C. Mehta v. Union of India (the Oleum case, 1986) and has none. This is the most examined topic in the group.
Exam focus
- Frequency: Frequently asked
- Usually asked as: Both (long answer and short answer)
Legal provision
Both rules are judge-made. The law comes from these sources.
- Rylands v. Fletcher (1868), House of Lords: a person who brings and keeps on land anything likely to do mischief if it escapes must keep it in at his peril. He is answerable for the natural consequence of its escape.
- M.C. Mehta v. Union of India (1986), Supreme Court: an enterprise in a hazardous or inherently dangerous activity owes an absolute and non-delegable duty to the community. It is liable for harm from an accident in that activity, without the Rylands exceptions.
- Article 21, Constitution of India: the right to life. The Supreme Court allowed compensation claims in a writ petition under Article 32 because a hazardous industry threatens this right.
- Section 17(3), National Green Tribunal Act, 2010: in an accident case the Tribunal applies the principle of no fault.
Meaning and definition
Strict liability is liability without proof of fault. The defendant is liable for the escape of a dangerous thing brought on to land for a non-natural use, subject to exceptions.
Absolute liability is the Indian rule for hazardous or inherently dangerous enterprises. Liability follows the harm. Taking all reasonable care is no answer, and no exception applies.
- 1868Rylands v. Fletcher states the rule of strict liability for escape.
- December 1984The Bhopal gas tragedy shows how weak the existing remedies are.
- December 1985Oleum gas leaks from the Shriram plant in Delhi.
- 20 December 1986The Supreme Court lays down absolute liability.
Detailed explanation
Step 1: the rule in Rylands v. Fletcher
The defendants built a reservoir on their land to supply their mill, through an engineer and a contractor. Water escaped through old filled-up shafts and flooded the plaintiff's mine. The owners knew nothing of the shafts and took no personal part. The House of Lords still held them liable.
The rule has two parts. The defendant must have brought on to the land, for his own purposes, a thing likely to do mischief if it escapes. The use must be non-natural, meaning more than the ordinary use of land. Lord Cairns drew the line between natural flow of water and water stored in quantity for a mill.
Example. A fertiliser company stores a large tank of ammonia on its land at Kandla. The tank fails and the gas drifts into the neighbouring plot. The company is liable under the Rylands rule without proof of negligence, unless an exception applies.
Step 2: why India needed a stricter rule
The Rylands rule was framed for nineteenth century England. In M.C. Mehta, oleum gas leaked from a plant in the crowded Kirti Nagar area of Delhi on 4 December 1985. A smaller leak followed on 6 December. The Supreme Court held that India need not remain tied to the conditions and defences of that rule. A hazardous industry in a populated area needed a stricter standard.
Step 3: the rule of absolute liability
The Court laid down three points.
- An enterprise engaged in a hazardous or inherently dangerous activity owes an absolute and non-delegable duty to the community that no harm results.
- If harm results from an accident in that activity, the enterprise is absolutely liable to compensate all those affected. Care is no answer and none of the Rylands exceptions applies.
- Compensation must match the size and capacity of the enterprise, so that it deters. This is the deep pocket idea.
Example. A pesticide plant near Bhopal follows every safety rule. A hidden defect in a valve releases toxic gas into a village. The plant is liable to every victim. It cannot plead that it took all care, or that a supplier made the defective valve.
Step 4: later use
In Indian Council for Enviro-Legal Action v. Union of India (1996), the Supreme Court held itself bound by the Oleum rule. It applied absolute liability and the polluter pays principle to chemical plants in Bichhri. In Vellore Citizens Welfare Forum v. Union of India (1996), the Court held that the precautionary principle and the polluter pays principle are part of Indian environmental law.
Exceptions and special rules
Exceptions to strict liability
In Rylands itself, the excuses were left open. Blackburn, J. named the plaintiff's own default. He said that act of God or vis major might also excuse. These words suggest it as a possible excuse, not a settled one. Later English cases settled the usual exceptions.
- Act of God: escape caused by natural forces no human foresight could guard against.
- Act of a stranger: a third party's unforeseeable act, outside the defendant's control.
- Plaintiff's own default: the plaintiff caused or contributed to the escape.
- Statutory authority: the activity was done under a statute.
- Consent of the plaintiff: the plaintiff agreed to the accumulation, as with a common benefit.
Absolute liability has no exceptions
The Oleum rule admits none of these. This is the main exam point.
A caution
The Oleum statement of the rule was later described by Ranganath Misra, C.J. in Union Carbide Corporation v. Union of India (1991) as essentially obiter and perhaps a good guideline for compensation. In 1996 the Supreme Court in the Bichhri case held the Oleum rule binding on it. Present law follows the 1996 decision.
Don't confuse: strict and absolute liability
| Point | Strict liability | Absolute liability |
|---|---|---|
| Source | Rylands v. Fletcher (England, 1868) | M.C. Mehta v. Union of India (India, 1986) |
| Trigger | Escape of a dangerous thing kept for non-natural use | Harm from a hazardous or inherently dangerous activity |
| Exceptions | Yes (act of God, stranger, plaintiff's default, statutory authority, consent) | None |
| Compensation | Ordinary damages for the loss | Matched to the size and capacity of the enterprise |
Inside the concept. A sugar mill's effluent lagoon overflows after an unprecedented cloudburst and floods the next field. The owner may plead act of God. This is strict liability, which allows the plea.
Just outside it. A chlorine plant leaks gas after sabotage by an unknown person. Under absolute liability the plant cannot plead the act of a stranger. It must still compensate the victims.
Common mistakes
- Saying Rylands v. Fletcher laid down absolute liability. It laid down strict liability with exceptions.
- Listing exceptions for absolute liability. There are none.
- Forgetting that Oleum grew out of a writ petition under Article 32 and the right to life.
- Writing that Rylands needs negligence. It does not.
- Omitting the compensation rule: size and capacity of the enterprise.
Apply it
Problem
A fireworks and chemical unit at Sivakasi stores explosive powder. A fire breaks out after lightning strikes the store. Neighbours are injured. The unit says lightning is an act of God and that it kept every safety rule. Can the neighbours claim?
Issue
Is the unit liable, and does act of God excuse it?
Rule
Under Rylands v. Fletcher, act of God may excuse. Under the Oleum rule, a hazardous enterprise is absolutely liable, with no exception.
Application
Storing explosive powder is a hazardous activity. If the Oleum rule applies, the plea of act of God and the plea of care both fail.
Conclusion
The neighbours can claim compensation from the unit without proving negligence. The amount depends on the unit's size and capacity.
Leading case laws
- Rylands v. Fletcher (1868)
Facts. A mill owners' reservoir burst through old shafts and flooded the plaintiff's mine.
Principle. A person who brings on land and keeps there anything likely to do mischief if it escapes must keep it in at his peril. Natural use gives no claim.
Why it matters. It is the source of strict liability. Care is not the question.
- M.C. Mehta v. Union of India (Oleum Gas Leak Case) (1986)
Facts. Oleum gas leaked from the Shriram plant in Delhi on 4 December 1985, and an advocate near the Tis Hazari courts died.
Principle. Absolute liability for hazardous enterprises, with no exceptions and compensation matched to the enterprise's size and capacity.
Why it matters. It is India's own departure from the English rule.
- Indian Council for Enviro-Legal Action v. Union of India (1996)
Facts. Chemical plants in Bichhri left about 2,440 tonnes of toxic sludge that polluted wells and soil.
Principle. The Court followed the Oleum rule of absolute liability and applied the polluter pays principle. It directed the Central Government to recover the cost of remedial measures.
Why it matters. It shows the Oleum rule applied to pollution by private industry.
- Vellore Citizens Welfare Forum v. Union of India (1996)
Facts. Tanneries in Tamil Nadu discharged untreated effluent that polluted the Palar river area.
Principle. The precautionary principle and the polluter pays principle are part of Indian environmental law. Polluters must pay for the victims and for restoring the damaged ecology.
Why it matters. It confirms the principles that support heavy compensation.
