Introduction
The doctrine of precedent is a cornerstone of the English legal system, and its operation depends on the ability to distinguish between the ratio decidendi and obiter dictum of a judgment. The ratio decidendi is the legal principle or rule that was essential for the court to reach its decision, and it is this part that forms the binding precedent for future cases. In contrast, obiter dicta are comments made ‘by the way’ which are not strictly necessary for the decision and are therefore not binding, though they may be persuasive (Holland and Webb, 2019). This essay will determine the ratio decidendi and identify key obiter dicta from the landmark House of Lords decision in Alcock v Chief Constable of South Yorkshire Police [1992] 1 AC 310, a case concerning claims for psychiatric injury by secondary victims.
The Ratio Decidendi
The case of Alcock arose from the 1989 Hillsborough football stadium disaster, where the defendant, the police force, had admitted negligence. The claimants were all relatives or friends of those killed or injured in the crush. None were in the pens where the crush occurred, and so were classed as ‘secondary victims’. They brought claims for psychiatric illness (nervous shock) caused by what they had seen or heard of the disaster. The House of Lords unanimously dismissed their appeals.
The ratio decidendi of Alcock is the set of restrictive control mechanisms established by the House of Lords that a secondary victim must satisfy to establish a claim for negligently inflicted psychiatric injury. These criteria were deemed necessary to limit the potential for indeterminate liability. Building on the earlier case of McLoughlin v O’Brian [1983] 1 AC 410, their Lordships held that a claimant must satisfy three key requirements. These are:
- A close tie of love and affection: The claimant must prove a close relationship with the primary victim. This relationship must be one of love and affection, the strength of which would make psychiatric harm reasonably foreseeable.
- Proximity to the accident: The claimant must be close to the accident in time and space. This generally means being present at the scene or coming upon its ‘immediate aftermath’.
- The means of shock: The shock must be caused by the claimant's own direct sight or hearing of the event or its immediate aftermath. It cannot be caused by being told about it by a third party.
In Alcock, the claimants failed because they could not satisfy these criteria, particularly those relating to proximity. For example, claimants who watched the events on live television were held not to have sufficient proximity of perception, as the broadcast code of ethics prevented the transmission of images of recognisable individuals suffering. Similarly, a claimant who identified his brother-in-law’s body at a temporary mortuary some eight hours after the event was held to be outside the ‘immediate aftermath’. The application of these tests to deny the claims is therefore the binding legal rule, or ratio, of the case.
Obiter Dicta
Alongside the binding ratio, the judgments in Alcock contain several examples of obiter dicta. These statements provided guidance on how the control mechanisms might be applied in different factual scenarios but were not essential to deciding the appeals before the court.
One significant obiter discussion concerned the class of persons who could be said to have a ‘close tie of love and affection’. Lord Keith of Kinkel suggested that there is a rebuttable presumption of such a tie for spouses and parents and children. For other relationships, such as siblings or fiancés, the tie would have to be positively proven (Horsey and Rackley, 2021). This was obiter because the court did not need to make a definitive ruling on these categories; it simply noted that the claimants in the case would have to prove this tie, which was assumed they could for the purposes of the appeal, but they failed on other grounds.
Another important obiter comment was made regarding the possibility of a claim arising from a live television broadcast. Lord Ackner stated that while the television images in the Alcock case were not sufficient to found a claim, he could not rule out the possibility that a future live broadcast of a horrific event which did not respect broadcasting codes and showed clear images of identifiable people suffering might be equivalent to direct sight of the event. This hypothetical consideration was not part of the reason for the decision, but a comment on how the law might apply in a different, future situation. This illustrates a classic example of an obiter dictum.
Conclusion
In conclusion, the decision in Alcock v Chief Constable of South Yorkshire Police is a key authority in the law of negligence for psychiatric injury. Its ratio decidendi is the strict, three-part test that a secondary victim must meet to establish the necessary foreseeability and proximity for a successful claim. This test requires a close tie of love and affection, proximity in time and space to the event or its immediate aftermath, and perception of the event or aftermath with one’s own unaided senses. The obiter dicta in the case, while not binding, have been highly influential, particularly the discussions around the evidential requirements for proving a loving tie and the hypothetical possibility of a claim arising from a particularly graphic live broadcast.
