Concept of Strict Liability in Torts

The law of torts generally requires proof of fault, negligence, or intention to impose liability. However, certain situations exist where liability arises even in the absence of fault. One of the most significant doctrines reflecting this principle is the doctrine of strict liability. It marks a shift from fault-based liability to risk-based liability, where the focus is on the nature of the activity rather than the conduct of the person.

The doctrine developed through judicial decisions and has played a crucial role in regulating hazardous activities. It ensures that a person who introduces a dangerous substance on his land bears responsibility if that substance escapes and causes harm.

Origin of the Doctrine of Strict Liability

The doctrine of strict liability originated from the landmark English case of Rylands v. Fletcher (1868). This case laid down a new principle of liability that did not depend on negligence or intention.

Justice Blackburn initially described the rule as one of “absolute liability.” However, the term was later refined by legal scholars, particularly Winfield, who pointed out that the rule was not truly absolute as it recognised several exceptions. Therefore, the term “strict liability” became more appropriate and widely accepted.

What is Doctrine of Strict Liability?

Strict liability refers to a situation where a person is held liable for damage caused by the escape of a dangerous thing from his land, even though there may be no negligence or wrongful intention.

The principle is based on the idea that certain activities are inherently dangerous. A person who engages in such activities must take full responsibility for any harm that results from them. Liability arises because of the risk created, not because of any fault.

Justice Blackburn formulated the rule in clear terms. According to him, a person who brings onto his land and keeps something likely to cause harm if it escapes must keep it at his peril. If it escapes and causes damage, he is prima facie liable for the consequences.

Rule in Rylands v. Fletcher

The case of Rylands v. Fletcher (1868) provides the foundation of the doctrine.

Facts of the Rylands v. Fletcher Case

Rylands, a mill owner, constructed a reservoir on his land to supply water for his mill. For this purpose, he employed an independent contractor. During construction, old mine shafts were discovered but were not properly sealed. These shafts connected to Fletcher’s coal mines.

After the reservoir was filled, water escaped through the shafts and flooded Fletcher’s mines, causing substantial damage.

Decision

Initially, the Court of Exchequer decided in favour of Rylands. However, the Court of Exchequer Chamber reversed this decision and held Rylands liable. The House of Lords later affirmed this rule with certain clarifications.

Principle Laid Down

The rule states that:

• A person who brings onto his land something dangerous,
• keeps it for his own purposes, and
• allows it to escape,

is liable for all damage caused by such escape.

The House of Lords in Rylands v. Fletcher added two important conditions:

• The use of land must be non-natural
• The dangerous thing must have been brought onto the land

Essential Elements of Strict Liability

To establish strict liability, certain essential elements must be satisfied. These elements define the scope and application of the doctrine.

Escape of Dangerous Thing

The first requirement is that a dangerous substance must escape from the defendant’s land to an area outside his control.

It is not sufficient that the dangerous thing exists on the land. There must be an actual movement of the substance from the defendant’s property to the plaintiff’s property or beyond.

The Bhopal Gas Tragedy provides a striking illustration. On the night of 2nd and 3rd December 1984, methyl isocyanate gas leaked from a factory and spread beyond the premises, causing thousands of deaths and long-term injuries. The damage occurred because the gas escaped to surrounding areas.

In contrast, in N. Narayanan Bhattathiripad v. Travancore Government (1956), the court held that there was no “escape” in the legal sense. The flooding of fields was caused by heavy rainfall and the presence of a dam, but the water was not considered to have escaped from stored accumulation in the manner required by the rule.

Thus, the concept of escape is central to the doctrine and must be clearly established.

Non-Natural Use of Land

The second essential element is that the defendant must be using the land in a non-natural manner.

Non-natural use does not merely mean artificial use. It refers to a special use that creates increased danger to others. This concept was explained in Rickards v. Lothian (1913), where it was stated that non-natural use must involve an unusual or extraordinary use of land that brings increased risk.

Examples of non-natural use include:

• Storage of large quantities of water under pressure
• Use of gas or electricity in bulk
• Storage or use of explosives
• Emission of noxious fumes
• Industrial operations involving hazardous substances
• Activities causing strong vibrations or involving poisonous materials

The determination of non-natural use depends on the context. What is considered non-natural in one place may be natural in another.

In Kana Ram Akhul v. Satidhar Chatterjee (1912), lowering land to obtain water for agricultural purposes was considered a natural use in the Indian context. The court held that such an activity did not attract strict liability.

Liability for Acts of Independent Contractors

A significant aspect of strict liability is that liability cannot be avoided by delegating work to an independent contractor.

In Rylands v. Fletcher (1868), Rylands was held liable even though the reservoir was constructed by a contractor.

Similarly, in T.C. Balakrishnan Menon v. T.R. Subramanian (1968), an explosive device used in a fireworks display caused injury. The court held that the defendant was liable despite the involvement of an independent contractor.

This principle ensures that responsibility remains with the person who introduces a dangerous activity, regardless of who performs the work.

Defences to Strict Liability

Although strict liability imposes liability without fault, it is not absolute. Several recognised defences allow the defendant to avoid liability in specific circumstances.

Default of the Plaintiff

If the damage is caused due to the fault of the plaintiff, the defendant is not liable. For example, if the plaintiff interferes with the defendant’s property and causes the escape, liability will not arise.

Consent of the Plaintiff

If the plaintiff has expressly or impliedly consented to the presence of the dangerous thing, the defendant is not liable. This defence is based on the principle of voluntary assumption of risk.

Common Benefit

If the dangerous thing is maintained for the mutual benefit of both parties, the defendant is not liable. This principle was applied in Carstairs v. Tylor, where a shared water storage system caused damage.

Act of Stranger

If the escape is caused by the act of a third party over whom the defendant has no control, liability does not arise.

Act of God

Natural events that are extraordinary, unforeseeable, and beyond human control provide a valid defence.

In Nichols v. Marsland (1876), unprecedented rainfall caused lakes to overflow and destroy bridges. The court held that the defendant was not liable, as the event was an act of God.

Statutory Authority

If the activity is authorised by law, the defendant is not liable unless negligence is proved. This defence of Statutory Authority recognises that certain activities are carried out in the public interest.

The principle was illustrated in Madras Railway Company v. Zamindar of Carvatenagram (1874), where the maintenance of irrigation tanks under a statutory system was treated differently from private activities.

Difference Between Strict Liability and Absolute Liability

The distinction between strict liability and absolute liability is important for a proper understanding of the doctrine.

Strict liability:

• Imposes liability without proof of negligence
• Recognises several defences
• Requires escape and non-natural use
• Originates from common law principles

Absolute liability:

• Imposes liability without any exception
• Does not allow defences such as act of God or act of stranger
• Represents a higher and more stringent standard of liability

Although Justice Blackburn initially used the term “absolute liability,” the rule in Rylands v. Fletcher (1868) is clearly one of strict liability due to the presence of exceptions.

Conclusion

The concept of strict liability represents a significant development in the law of torts. Originating from Rylands v. Fletcher (1868), it introduced a principle where liability arises from the nature of the activity rather than fault.

The doctrine requires the fulfilment of key elements such as escape and non-natural use of land. At the same time, it recognises certain defences that limit its application. This distinguishes it from absolute liability, which imposes a more stringent and unconditional responsibility.
