Tort Law
Strict and Absolute Liability
Compare the rule in Rylands v. Fletcher with India’s absolute liability rule for hazardous enterprises, including escape, defences and remedies.
The short answer
Strict liability under Rylands depends on dangerous accumulation, non-ordinary use and escape with recognised defences, while Indian absolute liability for hazardous enterprises removes those traditional exceptions.
Strict liability under Rylands v. Fletcher
Strict liability removes the need to prove negligence, but it does not remove the need to prove the rule’s own ingredients.
Dangerous accumulation
The defendant must bring onto land and keep something likely to cause mischief if it escapes. Water in great volume, gas, electricity and toxic material are familiar examples.
Non-ordinary use
The use must create an exceptional danger rather than amount to an ordinary and appropriate use of the land in its context.
Escape
The dangerous thing must move from a place under the defendant’s occupation or control to a place outside it. Injury confined within the defendant’s premises may require another cause of action.
Recognised defences
Traditional defences include claimant fault, consent or common benefit, act of God, act of a stranger and statutory authority, depending on the facts and jurisdiction.
India’s rule of absolute liability
M.C. Mehta developed a rule suited to enterprises carrying on hazardous or inherently dangerous activities in Indian conditions.
Absolute and non-delegable duty
The enterprise must ensure that no harm results from the hazardous activity. If harm occurs, reasonable care and delegation to another person do not answer liability.
No Rylands exceptions
The traditional exceptions to strict liability are unavailable. The enterprise created the exceptional risk and is expected to absorb the cost of resulting harm.
Capacity-linked compensation
The measure of compensation should have a deterrent effect and can reflect the magnitude and capacity of the enterprise, rather than treating serious industrial harm as a routine accident.
Statutory immediate relief
The Public Liability Insurance Act, 1991 provides a separate no-fault mechanism for immediate relief after accidents involving hazardous substances. It does not erase broader rights to compensation.
Strict liability under Rylands v. Fletcher: complete test
The rule does not impose liability for every dangerous thing. The claimant must establish each element before the traditional defences arise.
Dangerous accumulation
The defendant must bring onto land and keep something likely to cause mischief if it escapes. The risk is judged in context, not by a fixed list of substances.
Non-natural or extraordinary use
The use must create an exceptional danger beyond ordinary occupation of land, assessed through place, quantity, purpose and contemporary conditions.
Escape
The dangerous thing must move from an area under the defendant's occupation or control to a place outside it. Injury confined within the same controlled premises may fall outside Rylands while another tort remains possible.
Causation and foreseeable kind of harm
The escape must cause the claimed injury, and modern authority requires the type of damage to be a foreseeable consequence of escape.
Traditional exceptions to strict liability
The exceptions belong to the Rylands rule. They should not be imported into India's absolute-liability doctrine for hazardous enterprises.
Claimant's consent or common benefit
A genuinely shared arrangement or informed acceptance may affect liability, but mere knowledge of the accumulation is not necessarily consent to negligent danger.
Claimant's default
Where the claimant's own act is the effective cause of escape and damage, the rule may not apply.
Act of stranger or act of God
An unforeseeable independent stranger or extraordinary natural event may excuse the defendant where reasonable care could not anticipate or prevent the escape.
Statutory authority
The defence depends on statutory construction and protects only consequences necessarily authorised despite proper care.
Absolute liability and statutory environmental relief in India
M.C. Mehta created a stricter Indian rule for enterprises engaged in hazardous or inherently dangerous activity.
The enterprise owes an absolute and non-delegable duty to ensure that no harm results from the hazardous activity. If harm occurs, liability is not subject to the Rylands exceptions. The rule is tied to the enterprise's creation of exceptional risk and capacity to absorb and distribute the cost of accidents.
The Public Liability Insurance Act, 1991 provides prompt no-fault relief for accidents involving hazardous substances and requires insurance within its scheme. Environmental adjudication may also apply polluter-pays and restoration principles. These statutory routes supplement rather than erase the conceptual distinction between negligence, strict liability and absolute liability.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Rylands v. Fletcher
(1868) LR 3 HL 330
Facts: A landowner had a reservoir constructed over old mine workings. Water escaped through hidden shafts and flooded the claimant’s neighbouring mine.
Legal question: Can liability arise for escape of a dangerous accumulation even without proof that the landowner was personally negligent?
Held: A person who keeps a dangerous thing on land for a non-ordinary use may be liable when it escapes and causes foreseeable damage, despite absence of negligence.
Reasoning: A person who introduces an exceptional danger onto land must keep it there at their peril, subject to the rule’s requirements and recognised defences.
Why it matters: Use it to set out accumulation, non-ordinary use, escape and the traditional defences.
Read the judgmentM.C. Mehta v. Union of India
(1987) 1 SCC 395
Facts: Oleum gas escaped from a hazardous industrial unit operating in a densely populated part of Delhi, causing death and injury.
Legal question: Should an enterprise carrying on hazardous activity receive the traditional exceptions available under strict liability?
Held: An enterprise engaged in hazardous activity owes an absolute and non-delegable duty, and the Rylands exceptions do not apply.
Reasoning: The Court imposed an absolute and non-delegable obligation because the enterprise creates exceptional risk and is best placed to prevent and absorb the resulting harm.
Why it matters: Use it for the Indian rule of absolute liability and capacity-linked compensation.
Indian Council for Enviro-Legal Action v. Union of India
(1996) 3 SCC 212
Facts: Chemical industries in and around Bichhri village discharged toxic material that contaminated soil and groundwater and harmed local residents.
Legal question: Does responsibility for hazardous pollution include the cost of restoring the damaged environment?
Held: Polluting industries were responsible not only for harm to affected people but also for the cost of restoring damaged soil and groundwater.
Reasoning: The polluter must bear both victim compensation and remediation costs. Environmental restoration is part of making good the harm caused by hazardous industrial activity.
Why it matters: Use it to connect absolute liability with the polluter-pays principle and environmental remediation.

Questions students ask
Does strict liability mean liability for every accident?
No. The claimant must still prove the special ingredients of the rule and the defendant may rely on recognised defences.
Is the Public Liability Insurance Act the same as absolute liability?
No. The Act supplies statutory no-fault immediate relief for specified hazardous-substance accidents. Absolute liability is a broader judicial rule governing enterprise responsibility.
Is escape required for absolute liability under M.C. Mehta?
The Indian rule focuses on harm resulting from a hazardous or inherently dangerous enterprise and is not confined by every technical requirement or exception of Rylands v. Fletcher.
Can a hazardous enterprise use the act of God defence?
Not against the absolute-liability rule stated in M.C. Mehta. Traditional Rylands exceptions do not reduce that absolute and non-delegable obligation.
How is no-fault statutory relief different from full damages?
A statutory scheme may provide prompt relief on prescribed conditions and amounts. A separate civil or environmental proceeding may address fuller compensation and restoration subject to its own law.
