Yachuk v Oliver Blais Co Ltd [1949] AC 386

Facts

• Peter Yachuk, a nine-year-old boy, suffered severe burns after buying gasoline from the defendant, Oliver Blais Co Ltd, a fuel supplier.
• Peter falsely stated that the gasoline was for his mother’s car, and the defendant’s employee sold it to him without verifying the purpose.
• Peter and his friend used the gasoline to start a fire, resulting in an explosion that caused significant injuries to Peter.
• Peter’s parents sued the defendant for negligence, claiming the company owed a duty of care not to sell gasoline to children due to its dangerous nature.
• The defendant argued that Peter was contributorily negligent by misrepresenting the purpose for the gasoline and by using it recklessly.

Issues

1. Whether the defendant owed a duty of care to prevent the sale of gasoline to a child.
2. Whether Peter’s contributory negligence should reduce or eliminate his claim for damages.
3. What standard of care applies when assessing a child's contributory negligence.

Decision

• The House of Lords held that the defendant owed a duty of care to prevent the sale of gasoline to children, given the foreseeable risk of harm.
• The court found the defendant had breached this duty by failing to verify Peter’s claim about the gasoline’s use.
• The court concluded that Peter’s contributory negligence should be assessed by a standard proportionate to his age and maturity, not as that of an adult.
• Peter’s damages were reduced by 25% to account for his contributory negligence, rather than barring his claim entirely.

Legal Principles

• The standard of care for contributory negligence must be proportionate to a child's age, intelligence, and experience.
• Children cannot be held to the same standard of care as adults, given their limited capacity to understand and avoid risks.
• Foreseeability of harm and duty of care are central in negligence claims involving minors, especially with dangerous substances.
• Contributory negligence does not bar a child’s claim outright but may justify a reduction in damages.

Conclusion

The decision in Yachuk v Oliver Blais Co Ltd established that a child's contributory negligence must be measured by their age and maturity, ensuring a balanced and equitable approach to duty of care and liability in negligence claims involving minors.
