Tort Law: Psychiatric Harm

Psychiatric harm—historically referred to as "nervous shock"—is one of the most controversial areas of tort law. While the law has no trouble awarding damages for a broken leg, it is far more cautious when the "injury" is a mental illness. To prevent the "floodgates" of litigation from opening, the courts have established a series of rigorous "control mechanisms" that a claimant must satisfy. This article provides a comprehensive deep dive into the distinction between Primary and Secondary victims, the infamous "Alcock Criteria," and the medical requirement for a "Recognized Psychiatric Illness."

1. The Fundamental Threshold: Recognized Illness

The court will not award damages for "mere grief, anxiety, or distress." The claimant must prove they are suffering from a Recognized Psychiatric Illness (e.g. PTSD, clinical depression, or pathological grief) as defined by medical standards like the DSM or ICD. This must be proven by expert medical evidence (Hinz v Berry).

2. Primary Victims: The Zone of Danger

A Primary Victim is someone who was "involved, either mediately or immediately, as a participant" in an accident (Alcock). Crucially, they must have been in the Zone of physical danger, or reasonably believed they were (Page v Smith [1996]).

The Rule in Page v Smith

If physical injury was foreseeable, the defendant is liable for any psychiatric harm that follows, even if the harm itself was not foreseeable. "Psychiatric harm is just another way of being injured."

3. Secondary Victims: The Alcock Criteria

A Secondary Victim is someone who is not in physical danger themselves but suffers psychiatric harm after witnessing the death or injury of another (the Primary Victim). Following the Hillsborough disaster, the House of Lords in Alcock v Chief Constable of South Yorkshire Police [1992] established three strict "Proximity" tests:

1. Proximity of Relationship: The claimant must have a "close tie of love and affection" with the primary victim (rebuttably presumed for spouses and parent/child).
2. Proximity in Time and Space: The claimant must witness the accident or its "immediate aftermath" (McLoughlin v O'Brian).
3. Proximity of Perception: The harm must be caused by a "sudden shock" to the senses (seeing or hearing it). Seeing it on the news is not enough.

5. Critical Analysis & Academic Debate

Lord Steyn in White famously described the law of psychiatric harm as "a patchwork quilt of distinctions which are difficult to justify." Academics like Professor Mullany and Handford argue that the "Alcock Criteria" are arbitrary and cruel, particularly the requirement for a "sudden shock" (which excludes those who suffer harm from slowly caring for a dying victim). There is a growing movement for reform to treat mental and physical injury equally, though the "floodgates" argument remains a powerful deterrent for the judiciary.

6. Worked Example — Problem Scenario

ISSUE: Can (A) and (B) claim for psychiatric harm?

CLAIMANT A: A is a Primary Victim (in the zone of danger). Under Page v Smith, since physical harm was foreseeable, the train company is liable for his PTSD.

CLAIMANT B: B is a Secondary Victim. While he has a close relationship, he fails the "Proximity of Perception" test (Alcock) because he saw it on a screen, not with his own "unaided senses."

CONCLUSION: Passenger A succeeds; Man B fails.

Conclusion

Tort law’s treatment of the mind remains one of its most restrictive frontiers. While the "Alcock Criteria" provide certainty for defendants, they often leave meritorious claimants without a remedy. For the law student, this area is a masterclass in how policy considerations (the "Floodgates") can override the logical application of negligence principles.
