Pure psychiatric harm (historically “nervous shock”) is a psychiatric condition suffered without any accompanying physical impact on the claimant. It is distinguished from consequential psychiatric harm (which follows a physical injury and is compensated as part of that claim) and is subject to a restrictive “limited duty” regime driven by policy concerns about “floodgates”, diagnostic uncertainty, and fraudulent claims.
A Medically Recognised Illness
The claimant must suffer a medically recognised psychiatric illness (e.g. PTSD, clinical depression) or a shock-induced physical condition; mere grief, anxiety or distress is not enough. In Hicks v Chief Constable of South Yorkshire, claims for the distress suffered by victims before death at Hillsborough were rejected.
Primary Victims: the “Zone of Danger”
A primary victim is in the actual area of physical danger, or reasonably believes they are. Per Page v Smith, if physical harm was reasonably foreseeable, a duty extends to psychiatric harm even if the latter was not itself foreseeable. This was limited in Rothwell v Chemical & Insulating Co, where illness from fear of a future disease did not make the claimants primary victims. A subset are involuntary participants who believe they caused another’s death or injury (Dooley v Cammell Laird).
Secondary Victims: the Alcock Control Mechanisms
A secondary victim is outside the danger zone but suffers harm through witnessing another’s peril. Alcock v Chief Constable of South Yorkshire set four strict control mechanisms:
- Foreseeability / normal fortitude: a person of ordinary fortitude in the claimant’s position must foreseeably suffer illness; if met, the “egg-shell skull” rule applies to the extent of harm.
- Proximity of relationship: a close tie of love and affection (presumed for spouses, parents, children; proven otherwise).
- Proximity in time and space: presence at the event or its “immediate aftermath” — satisfied in McLoughlin v O’Brian (two hours later, family still covered in oil and mud), but not by a mortuary identification eight hours later in Alcock.
- Proximity of perception: injury through the claimant’s own unaided senses, not by being told or via television.
Rescuers and White
Although Chadwick v British Railways Board once treated rescuers favourably, White v Chief Constable of South Yorkshire held rescuers have no special status: a rescuer is a primary victim only if in the actual zone of danger; otherwise they must satisfy all the Alcock mechanisms.
The Shift in Paul v Royal Wolverhampton
In Paul v Royal Wolverhampton NHS Trust, the Supreme Court held that a secondary victim can recover only on witnessing an “accident” (an external, traumatic event), not a “medical crisis” or the manifestation of disease from clinical negligence. It removed the “sudden shock”/“horror” requirement (“no Richter scale for horror”), overruled Walters, and held a doctor’s duty does not extend to protecting a patient’s family from the trauma of witnessing the patient’s death.
Assumption of Responsibility and Occupational Stress
A duty may arise where the defendant has assumed responsibility for the claimant’s mental welfare, common in occupational stress cases. In Walker v Northumberland CC, an employer was liable for a breakdown caused by an excessive caseload, the test being whether harm to that particular employee was reasonably foreseeable.
Conclusion
Lord Steyn called the law a “patchwork quilt of distinctions which are difficult to justify”. Paul clarified clinical-negligence claims but reinforced the rigid, policy-driven Alcock mechanisms — a compromise between compensating genuine suffering and limiting the liability of defendants such as the NHS and police.
