Introduction
The rule of strict liability makes a person responsible for damage caused by the escape of dangerous substances from their land, even without negligence. However, the rule is not absolute. Courts have recognized certain situations where the defendant will not be held liable.
These situations are known as exceptions to the rule of strict liability.
Meaning / Definition
Exceptions to strict liability are circumstances in which the defendant can avoid liability even though a dangerous thing escaped from their land. If any of these exceptions apply, the defendant will not be responsible for the damage caused.
Modes or Types
Act of God (Vis Major)
An Act of God refers to a natural event that is extraordinary, unpredictable, and beyond human control. If the damage occurs due to such natural forces, the defendant will not be liable.
Examples include extremely heavy rainfall, earthquakes, floods, or storms that could not reasonably be anticipated.
Act of a Third Party
If the escape of the dangerous thing is caused by the act of an independent third person over whom the defendant has no control, the defendant is not liable.
The defendant must also show that there was no negligence on their part.
Plaintiff’s Consent
If the plaintiff has given consent to the accumulation or use of the dangerous thing, the defendant will not be liable for damage caused by its escape.
This principle is similar to the maxim volenti non fit injuria, meaning a person who willingly accepts a risk cannot later complain of injury.
Common Benefit of Plaintiff and Defendant
When the dangerous thing is kept for the joint benefit of both the plaintiff and the defendant, strict liability will not apply.
If both parties benefit from the activity and the defendant has not been negligent, the defendant is not liable for the damage.
Plaintiff’s Own Default
If the damage occurs because of the plaintiff’s own fault or negligence, the defendant will not be liable.
In such cases, the injury is considered to be caused by the plaintiff’s own conduct.
Statutory Authority
When a person performs an act that is authorized by a statute (law passed by the legislature), strict liability will not apply.
However, if the damage occurs because of negligence while performing the authorized activity, the defendant may still be liable.
Important Case Law
Nichols v. Marsland
The defendant created artificial lakes by damming a stream. Due to extremely heavy and unusual rainfall, the embankments broke and water destroyed the plaintiff’s bridges. The court held that the defendant was not liable because the damage was caused by an Act of God.
Ryan v. Young
A lorry driver died suddenly while driving and the vehicle injured the plaintiff. The court held that the defendant was not liable because the event was unexpected and beyond control.
State of Mysore v. Ramchandra
Damage occurred due to overflow of water from a storage system. The court rejected the defence of Act of God because the authorities failed to provide proper emergency outlets for excess water.
Box v. Jubb
A third party caused obstruction in a drain which forced water to overflow from the defendant’s reservoir onto the plaintiff’s land. The court held that the defendant was not liable because the escape was caused by the act of a third party.
Rickards v. Lothian
A stranger blocked waste pipes and opened water taps in a building, causing water to damage the plaintiff’s goods. The defendant was not held liable because the act was done by a third party without his knowledge.
Balakh Glass Emporium v. United India Insurance Co. Ltd.
Water escaped from an upper floor and damaged property on the lower floor. The court held that there was implied consent to the normal use of water, so the defendant was not liable.
Carstairs v. Taylor
A rainwater box maintained for the common benefit of landlord and tenant was damaged by rats and water escaped. The landlord was not held liable because the system was maintained for the benefit of both parties and there was no negligence.
Ponting v. Noakes
The plaintiff’s horse reached over the defendant’s boundary and ate poisonous leaves from a tree. The horse died. The court held that the defendant was not liable because the damage was caused by the plaintiff’s own fault.
Green v. Chelsea Waterworks
The defendants were authorized by statute to store water for public supply. Water accidentally escaped and caused damage. The court held that the defendants were not liable because the activity was authorized by statute and there was no negligence.
Distinction / Comparison
| Basis | Strict Liability | Exceptions to Strict Liability |
|---|---|---|
| General rule | Defendant is liable for escape of dangerous things | Defendant is not liable in certain recognized situations |
| Requirement | Escape, dangerous thing, non-natural use of land | Presence of specific legal defence |
| Examples | Escape of chemicals or water causing damage | Act of God, act of third party, statutory authority |
Practical Example
A factory stores chemicals in large tanks. Due to a severe and unexpected earthquake, the tanks break and chemicals escape, damaging nearby houses. Since the escape occurred due to an extraordinary natural event beyond human control, the factory may rely on the defence of Act of God.
