Contributory Negligence and its Defences

Negligence is one of the most important branches of the law of torts. It arises when a person fails to exercise reasonable care and such failure causes injury, loss or damage to another person. In ordinary cases of negligence, liability is imposed on the defendant because the injury has resulted from the defendant’s careless conduct. However, there are situations where the injured person himself has also acted negligently. Such situations give rise to the doctrine of contributory negligence.

Meaning of Contributory Negligence

Contributory negligence means negligence by the plaintiff which combines with the negligence of the defendant and contributes to the injury suffered by the plaintiff. It may also be described as the failure of the plaintiff to take reasonable care for his own safety.

It occurs when the plaintiff had the means and opportunity to avoid the consequences arising from the defendant’s negligence but failed to do so.

In cases of contributory negligence, three situations may arise:

1. The injury was caused solely due to the defendant’s negligence.
2. The injury was caused solely due to the plaintiff’s negligence.
3. Both the plaintiff and the defendant were negligent and both contributed to the injury.

The plaintiff succeeds in the first situation because the defendant alone is responsible. The plaintiff fails in the second situation because the injury resulted from his own negligence. The third situation gives rise to contributory negligence, where liability is apportioned according to the degree of negligence of both parties.

The doctrine is loosely connected with the maxim Volenti non fit injuria, which means that a person who voluntarily exposes himself to risk cannot later complain of the resulting injury.

Duty of Care and Negligence

The foundation of contributory negligence lies in the broader concept of negligence and duty of care. A person is expected to act reasonably and cautiously in order to avoid causing injury to others.

The modern concept of duty of care was developed in Donoghue v Stevenson. In that case, the plaintiff consumed ginger beer containing the remains of a decomposed snail and suffered illness. The House of Lords held that the manufacturer owed a duty of care to consumers.

Lord Atkin stated that every person must take reasonable care to avoid acts or omissions which can reasonably be foreseen to injure others.

The same principle also applies to plaintiffs. A plaintiff must take reasonable care for his own safety. Failure to do so may amount to contributory negligence.

Essentials of Contributory Negligence

For contributory negligence to apply, certain conditions must exist:

Negligence of the Defendant

There must first be negligence on the part of the defendant. If the defendant is not negligent, the question of contributory negligence does not arise.

Negligence of the Plaintiff

The plaintiff must also have failed to exercise reasonable care for his own safety.

Causal Connection

There must be a direct connection between the plaintiff’s negligence and the injury suffered.

Contribution Towards Damage

The plaintiff’s negligence must have materially contributed to the occurrence of the accident or the extent of damage.

Early Rule: Butterfield v Forrester

The classical rule relating to contributory negligence was laid down in Butterfield v Forrester.

In this case, the defendant had wrongfully placed a pole on the road while carrying out repairs. The plaintiff, while riding his horse at a fast speed, collided with the pole and suffered injuries. Evidence showed that the pole was visible from a considerable distance and the accident could have been avoided through ordinary care.

The court held that the plaintiff could not recover damages because he himself failed to exercise reasonable caution.

Lord Ellenborough observed that one person’s fault does not excuse another from taking ordinary care for his own safety.

This decision established a harsh principle that even slight negligence by the plaintiff could completely bar recovery.

Rule of Last Opportunity

The strict rule in Butterfield v Forrester later underwent modification through the rule of last opportunity.

Davies v Mann

The rule was developed in Davies v Mann.

In this case, the plaintiff left his donkey fettered on a public road. The defendant drove his wagon at a very high speed and ran over the donkey, causing its death.

Although the plaintiff was negligent in leaving the donkey on the road, the court held the defendant liable because he had the last opportunity to avoid the accident by driving carefully.

The court observed that even though the animal was wrongfully present on the road, the defendant was still required to drive cautiously.

The rule of last opportunity means that where both parties are negligent, the party who had the final opportunity to avoid the accident but failed to do so will be held liable.

British Columbia Electric Co. v Loach

The principle was further applied in British Columbia Electric Railway Co. v Loach.

In this case, a tram collided with a cart at a railway crossing. The tram could not stop because its brakes were defective. Although the cart driver was negligent in failing to observe the approaching tram, the defendants were held liable because they had the last opportunity to avoid the accident by maintaining proper brakes.

Apportionment of Damages

Modern law no longer follows the rigid common law rule that contributory negligence completely bars recovery. Courts now apportion damages according to the degree of negligence of each party.

Vidya Devi v M.P. State Road Transport Corporation

In Vidya Devi v M.P. State Road Transport Corporation, a motorcyclist collided with a bus and died. The court found both parties negligent. However, the motorcyclist was held more negligent than the bus driver.

The negligence was apportioned in the ratio of two-thirds and one-third. Therefore, compensation was reduced accordingly.

Maya Mukherjee v Orissa Co-operative Insurance Society Ltd.

In Maya Mukherjee v Orissa Co-operative Insurance Society Ltd., a collision between a motorcycle and a car resulted in the death of the motorcyclist. The court held the motorcyclist 60% negligent and the car driver 40% negligent. Compensation was awarded proportionately.

Vidya Soni v Pushpesh Dwivedi

In Vidya Soni v Pushpesh Dwivedi, the tribunal had reduced compensation on the ground that the deceased did not possess a licence and the vehicle was uninsured. However, the High Court held that there must be a causal connection between the violation and the accident.

The mere absence of a licence did not amount to contributory negligence unless it contributed to the accident itself.

Doctrine of Alternative Danger

The doctrine of alternative danger applies where the defendant’s negligence places the plaintiff in a dangerous situation and the plaintiff takes immediate action to escape the danger.

If the plaintiff acts reasonably in the circumstances, the defendant cannot plead contributory negligence.

Jones v Boyce

The principle was recognised in Jones v Boyce.

The plaintiff was travelling in the defendant’s coach. Due to negligent driving, the plaintiff reasonably believed that his life was in danger and jumped from the coach, suffering injuries.

The defendant argued that the plaintiff would not have been injured had he remained seated. The court rejected this argument and held that the plaintiff acted prudently in the emergency situation created by the defendant.

Lord Ellenborough stated that where the defendant’s misconduct forces the plaintiff to choose between danger and safety, the plaintiff’s reasonable response does not amount to contributory negligence.

Contributory Negligence by Children

The rule of contributory negligence is generally applied differently in the case of children because children lack the maturity and judgment expected from adults.

Motias Costa v Roque A. Jacinto

In Motias Costa v Roque A. Jacinto, a six-year-old child was knocked down by a motorcycle while crossing the road near his school.

The court rejected the plea of contributory negligence and held that a child cannot be expected to behave with the same level of caution as an adult.

Alka v Union of India

In Alka v Union of India, a six-year-old child entered an unattended room containing a running electric motor and suffered serious injuries.

The defendant was held liable because proper precautions had not been taken to prevent children from accessing the dangerous area.

S.M. Railway Co. Ltd. v Jayammal

In S.M. Railway Co. Ltd. v Jayammal, a seven-year-old girl was injured while crossing a railway line. The court held her responsible because she was capable of understanding the danger involved.

Thus, courts determine contributory negligence by children based on age, maturity and ability to understand risk.

Doctrine of Identification

The doctrine of identification means that in certain situations, the negligence of one person may be imputed to another person with whom he has a legal relationship.

For example, the negligence of a servant may be identified with the master.

Bernina Mills v Armstrong

The doctrine was discussed in Bernina Mills v Armstrong.

Two ships collided due to negligence on both sides, resulting in the death of passengers. The defendants argued contributory negligence by identifying the victims with the negligence of their carrier.

The House of Lords rejected this argument and held that the passengers could not be identified with the negligence of the ship owner.

Burden of Proof

The burden of proving contributory negligence lies on the defendant.

The defendant must prove that:

• the plaintiff failed to exercise reasonable care; and
• such failure contributed to the injury.

If the defendant fails to raise this plea, the plaintiff is not required to disprove contributory negligence.

For example, a person attempting to board a moving bus and falling due to loss of balance may himself be responsible for the accident because boarding a moving vehicle is inherently risky.

Situations Where Defence of Contributory Negligence is Not Available

There are several situations where the defence cannot be successfully raised.

Defendant Had Last Opportunity

If the defendant had the final opportunity to avoid the accident, the defence fails. This principle was recognised in Davies v Mann.

Alternative Danger

Where the plaintiff acted under imminent danger created by the defendant, contributory negligence does not apply. Jones v Boyce is an example.

Children

Children are generally not held to the same standard of care as adults.

Strict Liability

Contributory negligence is generally not a defence in strict liability cases.

In Rylands v Fletcher, the defendant constructed a reservoir which burst and flooded the plaintiff’s mine. The rule established that a person keeping dangerous substances on his land is liable for escape causing damage.

Although contributory negligence may reduce compensation, it does not completely absolve liability in strict liability cases.

Composite Negligence

Composite negligence differs from contributory negligence.

In contributory negligence, the plaintiff himself is negligent. In composite negligence, two or more defendants are negligent towards the plaintiff.

The liability in composite negligence is joint and several.

Hira Devi v Bhaba Kant Das

In Hira Devi v Bhaba Kant Das, an accident occurred due to negligence by both a bus driver and a car driver. The tribunal apportioned damages between them.

The High Court held that the plaintiff could recover the entire compensation from any one of the tortfeasors because their liability was joint and several.

The tortfeasor paying more than his share could later seek contribution from the other wrongdoer.

Conclusion

Contributory negligence is an important doctrine under the law of torts which seeks to balance responsibility between the plaintiff and the defendant. The doctrine recognises that a person must take reasonable care for his own safety and cannot entirely shift blame to another person when his own negligence has contributed to the injury.

The early common law rule completely barred recovery if the plaintiff was negligent in any manner. However, courts gradually realised that such rigidity often resulted in injustice. Consequently, principles such as the rule of last opportunity, apportionment of damages and alternative danger evolved to achieve fairness.
