Nervous Shock CASES

In English law, nervous shock is the traditional term used to describe claims in negligence for psychiatric injury. Although modern
judgments often prefer the language of psychiatric harm, the expression nervous shock remains widely used to denote the specific legal rules and control mechanisms governing such claims.

Definition and principles

Nervous shock refers to a medically recognised psychiatric illness caused by sudden shock or traumatic events, rather than by gradual stress, anxiety, or grief alone. Ordinary emotions such as sorrow or distress are not sufficient. The claimant must show a recognised psychiatric condition and establish a duty of care under restrictive principles developed to limit liability.

The law distinguishes between primary victims, who are directly involved in the incident and exposed to danger, and secondary victims, who suffer psychiatric injury from witnessing or learning of harm to others. Secondary victims must satisfy additional control mechanisms, including close ties of love and affection, proximity in time and space to the event, and direct perception of the shocking incident.

Common examples

Nervous shock claims commonly arise from road traffic accidents, workplace disasters, medical negligence involving traumatic outcomes, and large-scale incidents such as stadium or transport disasters. Claims by relatives who witness serious injury or death are subject to
particularly strict scrutiny.

Key cases

• Dulieu v White & Sons: early recognition of recovery for psychiatric injury caused by shock.
• Alcock v Chief Constable of South Yorkshire Police: established the modern control mechanisms for secondary victims.
• Page v Smith: confirmed that primary victims need only show foreseeability of personal injury.
• McLoughlin v O’Brian: recognised recovery where shock is experienced shortly after the event.
• White v Chief Constable of South Yorkshire Police: clarified limits on claims by rescuers.

Legal implications

Nervous shock remains one of the most restrictive areas of negligence. Even where psychiatric injury is genuine and severe, claims may fail
if the control mechanisms are not satisfied. Courts justify these limits by reference to policy concerns, including indeterminate liability
and the need for clear boundaries on duty of care.

Practical importance

The doctrine is essential for understanding how negligence law balances compassion for psychiatric harm against limits on legal
responsibility. It is frequently examined in legal education and remains highly relevant in litigation involving traumatic incidents and
mass harm.
