10. Negligence: nervous shock

What is Nervous Shock?

Definition: In the law of torts, 'nervous shock' refers to a recognised psychiatric illness or physical damage triggered by the sensorial impact of an event on the mind. Unlike ordinary grief, sorrow, or emotional distress, nervous shock must result in a medically certified psychiatric condition.

Scope of harm: While physical injuries from negligence are usually limited to those directly within the range of physical danger, psychiatric trauma can potentially affect a much wider circle of people who witness or experience the aftermath of a catastrophic event.

Why Courts Were Initially Reluctant

Policy concerns: Historically, common law judges hesitated to award damages for nervous shock. They doubted whether psychiatric injury was a genuine medical condition, feared that claimants could easily fake symptoms, and struggled with conflicting psychiatric evidence in court.

The floodgates argument: The courts also feared opening the 'floodgates' of litigation, worrying that allowing these claims would result in an unmanageable rush of lawsuits against defendants. Over time, however, as modern medical science consistently proved that mental trauma causes genuine, diagnosable psychiatric illness, the courts broadened their approach.

The Early Rule: Fear for Personal Safety

Immediate fear: The first major step toward recovery was established in Dulieu v White & Sons. In this case, the court ruled that the claimant could recover damages for nervous shock because she suffered a reasonable and immediate fear of personal physical injury to herself. At that early stage, liability was strictly confined to fear for one's own safety.

The Modern Approach: The McLoughlin Test

Expanding liability: The law evolved significantly in McLoughlin v O'Brian, where a mother suffered severe psychiatric injury after seeing her injured family members at the hospital shortly after a road accident. The House of Lords held that her nervous shock was a reasonably foreseeable consequence of the defendant's negligence and allowed her claim.

The three control mechanisms: To prevent unlimited liability, Lord Wilberforce laid down three essential elements that must be satisfied for a secondary victim to recover damages for psychiatric harm:

1. Class of persons: The claimant must have a close tie of love and affection with the primary victim. This relationship is readily presumed between spouses or parents and children, but claims by ordinary bystanders or more distant relatives are subjected to strict scrutiny.

2. Proximity in time and space: The claimant must be sufficiently close to the accident in both time and location. The courts recognise that insisting on strictly witnessing the accident itself would be unfair, so experiencing its 'immediate aftermath'—such as seeing the injured victims before their condition changes—is sufficient to establish proximity.

3. Means of perception: The psychiatric illness must be caused by what the claimant saw or heard with their own unaided senses, rather than being told about the incident second-hand. For example, in Hambrook v Stokes Bros, the claimant succeeded because her shock was produced by her own direct sensory perception of a runaway lorry threatening her children, rather than mere information delivered by others.

Witnessing Injury to Family and Property

Shock from injury to relatives: Where a claimant witnesses an accident or its immediate aftermath involving their loved ones and suffers psychiatric illness as a result, the defendant will generally be held liable in negligence. This principle was applied in Brice v Brown, where the defendant was held liable for the psychiatric illness suffered by a mother who witnessed a horrific accident involving her daughter.

Shock from destruction of property: Nervous shock is not limited strictly to witnessing harm to human beings. In Attia v British Gas plc, the court held that a claimant could recover damages for nervous shock after returning home to witness her house being destroyed by a fire caused by the defendant's negligent installation of a central heating system.
