⚡ The short answer
Strict liability means paying for harm though you weren't careless. Under Rylands v Fletcher, if a dangerous thing you keep for a non-natural use of land escapes and causes damage, you pay however careful you were. Five exceptions: act of God, act of a stranger, the plaintiff's own fault, consent and statutory authority.

Tara's ruling: Kabir pays. He brought a mass of water onto his land, a non-natural use, and it escaped. His care, and his choice of contractor, don't matter.
What is strict liability in tort?
Most of tort runs on fault: you pay because you were careless or meant harm. Strict liability is the exception. Some things are so risky to keep that the law says: keep it at your own peril. If it escapes and does damage, you pay.

Strict liability
A passage will say: "A person who brings on his land anything likely to do mischief if it escapes keeps it at his peril, and is liable for the damage even without negligence." Each phrase is a condition.
📌 What CLAT actually expects
The passage gives the rule and usually the exceptions. Tick each condition against the facts, then check whether a listed exception fits. Never import a defence the passage didn't give.

Strictly liable, however careful he was
1. A dangerous thing, brought there by him
"Dangerous" means likely to do mischief if it escapes. Water is harmless in a glass and lethal in a reservoir. Gas, electricity, explosives, sewage and fumes all qualify. He must have brought or collected it for his own purposes; rainwater or weeds arriving on their own don't count.
2. Non-natural use of land
Added by the House of Lords. Non-natural use is some special use bringing increased danger to others, not ordinary use or a use for the community's general benefit.
🎚️ The scale
Natural or non-natural use?
← Ordinary livingSpecial, extra risk →
Household water, wiring
e.g. natural use
Fire in the fireplace
e.g. natural (Sochacki v Sas)
Ordinary trees
e.g. natural; poisonous ones differ
A huge reservoir
e.g. non-natural (Rylands)
Explosives, bulk chemicals
e.g. non-natural
Context matters: fireworks on an open ground at a temple festival were still non-natural, since explosives need a licence even then (Balakrishnan Menon, Kerala HC).
3. Escape, then damage
The thing must leave the area the defendant occupies or controls. Yew branches reaching over the fence to poison a neighbour's horse have escaped. A horse that wanders into the defendant's field to eat them has not.
⚠️ The contractor excuse doesn't work
Normally you aren't liable for an independent contractor's wrong. Not here: in Rylands the contractors were careless and the owner still paid.
What are the exceptions to strict liability?
"Strict" is not "absolute". Later cases settled on five exceptions; a passage may list all, some or none.
🧩 At a glance
The five ways out
⛈️Act of God
A force no human foresight could guard against.
🕵️Act of a stranger
An unforeseeable act of someone outside his control.
🙋Plaintiff's own default
The victim caused the escape, or his oversensitive use caused the harm.
🤝Consent
Express, or implied from common benefit.
📜Statutory authority
A law required it, done without negligence.
Act of God: only the truly extraordinary
In Nichols v Marsland, artificial lakes burst after the heaviest rainfall in living memory; no liability. A normal monsoon or strong wind is foreseeable. Ask: could anyone plan for it?
Act of a stranger: only if you couldn't see it coming
⚔️ Side by side
Stranger's act: defence or not?
✅Defence works
the act was unforeseeable
- •Strangers block a drain; the reservoir overflows (Box v Jubb)
❌Defence fails
the act was foreseeable and preventable
- •A power thief's line snaps onto a road (Shail Kumari)
VS
| Test | Defence works | Defence fails |
|---|---|---|
| Key test | Could not be anticipated | Should have been anticipated |
| Result | Not liable | Liable |
The more dangerous the thing, the more you must foresee others' mischief.
Plaintiff's default and the oversensitive neighbour
If the victim caused the harm, say by trespassing, he can't complain. Nor can one hurt mainly by his unusually sensitive use: stray tram current disturbing a delicate telegraph cable gave no claim.
Consent, common benefit and statutory authority
Tenants impliedly consent to the shared tank and pipes, so a leak from upstairs without negligence gave no claim (Carstairs v Taylor). A water company bound by law to keep its mains full wasn't liable for a non-negligent burst (Green v Chelsea Waterworks).
ℹ️ India's own twist: irrigation tanks
Ancient irrigation tanks feeding thousands of farmers were held a necessity, so their owner was liable only if negligent (Madras Railway v Zamindar of Carvatenagaram).
How is strict liability different from negligence and absolute liability?
| Negligence | Strict liability | Absolute liability | |
|---|---|---|---|
| Must the victim prove fault? | Yes | No | No |
| What triggers it? | Breach of a duty of care | Escape of a dangerous thing from non-natural use | Any harm from a hazardous or inherently dangerous enterprise |
| Escape needed? | No | Yes | No |
| "I took all care" works? | Yes | No | No |
| Exceptions? | General defences | The five above | None |

Which cases should you know for strict liability?
🌊
Landmark case · 1868 · House of Lords
Rylands v Fletcher
📋
What happened
A mill owner's contractors built a reservoir over old mine shafts without blocking them. The water burst through and flooded the neighbour's coal mine.
❓
The question
Is the owner liable without any negligence of his own?
🔨
What the court held
Yes. He brought the water there, it was a non-natural use, and it escaped.
What CLAT takes from it: Your care, and your contractor's fault, are irrelevant.
💣
Landmark case · 1946 · House of Lords
Read v J Lyons & Co
📋
What happened
A munitions inspector inside a shell factory was hurt when a shell exploded. No negligence was proved.
❓
The question
Does the rule cover harm that never left the premises?
🔨
What the court held
No. Escape to a place outside the defendant's control is essential.
What CLAT takes from it: Check for escape first.
⚡
Landmark case · 2002 · Supreme Court
M.P. Electricity Board v Shail Kumari
📋
What happened
A cyclist rode over a live wire on a flooded road at night and was electrocuted. The Board blamed a power thief's illegal tap.
❓
The question
Can the Board blame the stranger?
🔨
What the court held
No. Pilferage should have been anticipated, and a snapped line should cut off automatically.
What CLAT takes from it: The stranger exception fails if the act was foreseeable.

Escape of fire
Legal Principle: A person is liable to compensate others for harm caused by the escape of any inherently dangerous material that he keeps on his land.
Fact Situation: Ankit lights a bonfire in his courtyard to warm himself up during a cold winter evening. A strong wind suddenly blows some sparks from the fire, on to his neighbour's house which catches fire and gets completely destroyed.
Which of the following statements is the most appropriate in relation to the legal principle stated above?
AAnkit's neighbour is liable to Ankit for distress caused by keeping a house that catches fire so quickly.
BAnkit is not liable because nobody could foresee that the sudden wind will blow the sparks to cause a fire.
CAnkit's neighbour cannot make Ankit liable for the loss of his house since it was an accidental fire that destroyed it.
DAnkit is liable to compensate because the fire escaped from his premises to burn down his neighbour's house.
Reveal answer + reasoning
Answer: D
The principle has two conditions: a dangerous thing kept on his land, and an escape causing harm. Both met (the paper numbered options 1–4; the key gives 4). It gives no act of God exception, so don't add one. Even in real law, a winter wind is foreseeable.
Why the others fail
- A — Inverts the rule; the victim owes nothing.
- B — Foreseeability is a negligence idea. Strict liability ignores it.
- C — "Accidental" is exactly what strict liability covers.

Hazardous escape
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
Hazardous substance, escape "in any manner", damage: liable, fault irrelevant. The "in any manner" wording even covers A's own workers, whom Read v Lyons might exclude.
Why the others fail
- A — Backwards: outsiders are the clearest case of escape.
- C — Fault is not a condition of this rule.
- D — Expectation is a negligence question, not a strict liability one.

Strict vs absolute
Principle 2: Strict Liability. Any person who uses his/her land in an 'unnatural manner' and who keeps any 'hazardous substance' on such premises would be held liable … for any 'damage' occurred on the 'escape' of such perilous substance. … the principle also 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 when it happens with the consent of the person injured or with statutory authority.
Principle 3: Absolute Liability … is devoid of any exceptions that were mentioned under the earlier principle. Principle 1 (Polluter Pays): … the person who damages or destructs the environment has the absolute obligation to bear the cost of ameliorating the environment.
A company ABC limited operates an industrial chemical plant. Due to an earthquake on July 22, 2020, 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
Run each principle separately. Strict: an earthquake is a natural calamity, the passage's own act of God, so ABC escapes. Absolute: no exceptions, so it pays. Polluter pays: it polluted, so it pays.
Why the others fail
- A — Ignores the act of God exception.
- C — Absolute liability has no exits.
- D — Gets strict liability and polluter pays wrong.
Also asked here: Q76 (liable under all three, D), Q79 ("we didn't know it could leak" helps under none, C), Q80 (turns on whether the gas was hazardous, C).

🎯 Quick quiz
Apply the rule, not your instinct
0 / 5
A building's shared overhead tank cracks without negligence and floods Rohan's ground-floor flat. Zoya, the owner, lives upstairs.
Q1. Is Zoya strictly liable?
Shared domestic water is natural use and impliedly consented to (Carstairs).Kabir's festival committee hires a licensed fireworks firm. A rocket veers into the crowd and injures Meher.
Q2. Can Kabir blame the firm?
Spectators share no common benefit in explosives, and the duty can't be delegated.A passage makes a person liable when a dangerous thing he keeps escapes from his land. A cylinder bursts inside Kabir's warehouse, injuring Aarav, a worker there.
Q3. Is Kabir liable under this rule?
No escape, so this rule isn't triggered. Drop the escape condition and it flips.Power theft is rampant in a colony and the supplier knows it. A thief's tap snaps and the live wire injures Zoya.
Q4. Can the supplier plead act of a stranger?
Known pilferage must be guarded against (Shail Kumari).Rohan's fish pond overflows in the usual heavy monsoon of a high-rainfall district, flooding Aarav's fields.
Q5. Does act of God save Rohan?
Only extraordinary events, like Nichols' record rainfall, qualify.🎯 Strict liability in a nutshell
- Four checks: dangerous thing, non-natural use, escape, damage.
- Care is irrelevant; a contractor's fault is still yours.
- Five exceptions: act of God, stranger, plaintiff's default, consent, statute.
- Act of God and stranger fail if the event was foreseeable.
- Exceptions allowed: strict. None, hazardous industry: absolute.
📎 Good to know, not to memorise

Frequently asked questions
What is the rule in Rylands v Fletcher in simple words?
If you bring onto your land something likely to cause harm if it gets out, and your use of the land is special and risky, you keep it at your own risk. If it escapes and causes damage, you pay, however careful you were.
What are the exceptions to strict liability?
Five: act of God, act of a stranger, the plaintiff's own default, consent (often implied from common benefit) and statutory authority. Some books add natural use of land, though that really means a condition of the rule is missing.
What is the difference between strict and absolute liability?
Neither needs fault. Strict liability needs non-natural use and escape, and allows five exceptions. Absolute liability, from the Oleum gas case, covers hazardous enterprises, needs no escape and allows no exceptions at all.
Does strict liability still apply in India after MC Mehta?
Yes. Absolute liability covers hazardous enterprises; elsewhere courts apply Rylands. In 2002 the Supreme Court held an electricity board strictly liable for a live wire on a road and rejected its act-of-a-stranger defence.
What does non-natural use of land mean?
A special use that brings increased danger to others. Household water, wiring and a fire in the fireplace are natural uses. A huge reservoir, bulk chemicals and explosives are non-natural.
