Liability in Negligence: Core Principles

Negligence is a civil wrong (a tort) where a person breaches a duty of care owed to another, resulting in damage. The following principles govern how courts determine liability and accountability.

Key Liability Types

Liability in negligence primarily concerns personal accountability, but it expands to cover broader relationships.

👤

Personal Liability

The defendant is directly responsible for their own negligent conduct.
🤝

Vicarious Liability

One person held liable for the negligence of another (e.g., employer-employee acts in course of employment).
🔗

Joint Liability

Two or more parties found liable for the same tortious harm; claimant can recover full loss from any defendant.

The Caparo Test for Duty of Care

The modern approach, derived from Caparo Industries plc v Dickman (1990), requires satisfying three key criteria.

1

Foreseeability of Harm

Could the defendant reasonably foresee that their conduct might harm the claimant?
2

Proximity

A relationship of closeness or directness between defendant and claimant (physical, circumstantial, or causal).
3

Fair, Just, and Reasonable

The court must decide if imposing a duty is appropriate in the circumstances, considering policy implications.

Policy and the Duty of Care

The Public Policy Barrier

Policy considerations are crucial at the final stage of the Caparo test. Courts assess the social utility of the defendant’s actions, the burden of imposing the duty, potential floodgates of litigation, and the need to limit liability in some areas to prevent excessive restrictions on beneficial activities.

For example, in Hill v Chief Constable of West Yorkshire (1989), the police were not liable for failing to prevent a serial killer’s crimes because imposing a duty would be unfair and not just.

Breach of Duty: The Standard of Care

💡

The Reasonable Person Test: The standard is objective; it is based on how an ordinary, competent person would behave in the defendant’s position. The reasonable person is cautious but not paranoid or negligent. Factors affecting this include the likelihood of harm, seriousness of potential harm, and the burden of taking precautions.

Adjusting the Standard

The standard of care adjusts based on the defendant's specific context (age or expertise).

🤔
How do we judge a doctor versus a child?
🦉
A child's behavior is judged against a reasonable child of similar age (Mullin v Richards). An expert must meet the standard of a reasonably competent practitioner (Bolam Test).

Factual Causation: The 'But For' Test

The claimant must prove the breach was a necessary prerequisite for the damage suffered.

Harm = (Breach Occurred) ? Yes : No
But for the defendant’s breach, would the harm have occurred? If the answer is no, factual causation is established.

*Legal causation limits liability to consequences sufficiently connected, excluding damages too remote (Wagon Mound) or caused by independent acts (novus actus interveniens).

Liability for Pure Economic Loss

✅
Recognized Liability: Liability for negligent misstatement (incorrect advice or information) causing financial loss was recognised in Hedley Byrne & Co Ltd v Heller & Partners Ltd (1964) where a special relationship existed with assumption of responsibility.
❌
Traditional Caution: Pure economic loss is financial loss not connected to physical injury or damage to property. Traditionally, courts have been cautious in imposing liability due to fears of indeterminate liability and 'floodgates'.

Limits on Psychiatric Injury Claims

Claims for nervous shock are carefully controlled, limiting them to claimants suffering recognized medical conditions caused by sudden traumatic events (Alcock v CC of South Yorkshire).

✓

Recognized Condition

The claimant must suffer a recognized medical condition (not just grief or distress).
✓

Proximity Required

Requires proximity in time and space to the event, and a close relationship of love and affection to the primary victim.
