Case Name: Robinson v Chief Constable of West Yorkshire Police [2018]

Robinson v Chief Constable of West Yorkshire Police

Supreme Court of the United Kingdom, 2018

[2018] UKSC[1]

Court Name and Bench

The case was decided by the Supreme Court of the United Kingdom. The judgement was delivered by Lord Reed, with whom Lady Hale and Lord Hodge agreed, resulting in a unanimous decision.[2]

Date of Judgement

The judgement was delivered on 8 February 2018.[3]

Parties Involved

The claimant and appellant, Mrs. Elizabeth Robinson, a 76-year-old pedestrian, brought a negligence claim following injuries sustained during a police arrest on a public street.

The defendant, serving as the Chief Constable of West Yorkshire Police, was sued in a representative capacity for the actions of the police officers involved in the arrest.[4]

Facts of the Case

In July 2008, police officers in plain clothes attempted to arrest a suspected drug dealer on Kirkgate, a shopping street in the centre of Huddersfield. The arrest took place in a public area where pedestrians were present, with officers positioned to prevent the suspect from escaping. When the officers attempted to effect the arrest, the suspect resisted, and a physical struggle followed.

As the officers and the suspect moved along the pavement, they collided with Mrs Elizabeth Robinson, a pedestrian who had just passed them.  The initial contact occurred when the suspect backed into her, causing her to fall to the ground, after which the officers and the suspect fell on top of her as the struggle continued. Mrs Robinson sustained personal injuries as a result.[5]

Issues Raised:

The principal issues before the Supreme Court were:

1. Whether the existence of a duty of care in negligence always requires the application of the Caparo criteria, or whether established principles of negligence were sufficient to determine liability in the present case.
2. Whether there exists a general rule that the police owe no duty of care when exercising their functions of investigating and preventing crime, or whether the police are subject to the ordinary duty to avoid causing reasonably foreseeable personal injury.
3. Whether the present case involved a mere omission by the police or instead concerned a positive act capable of giving rise to liability in negligence.
4. Whether, on the facts, the police officers owed a duty of care to Mrs Robinson and, if so, whether the Court of Appeal was entitled to overturn the Recorder’s findings on breach and causation.[6]

Arguments of the Parties

The appellant, Mrs Robinson, argued that the police officers owed her a duty of care under ordinary principles of negligence. It was submitted that the officers’ decision to carry out an arrest in a busy public street constituted a positive act which created a foreseeable risk of physical injury to nearby pedestrians. As a bystander with no connection to the arrest, Mrs Robinson argued that she fell within the class of persons to whom the officers should reasonably have had regard. The appellant contended that no general immunity applied to the police in such circumstances, and that liability should be assessed in the same way as for any other defendant.[7]

The respondent, the Chief Constable of West Yorkshire Police, argued that no duty of care was owed to Mrs Robinson. It was submitted that the police should not be subject to negligence liability when performing their core operational functions of crime prevention and investigation. Relying in particular on Hill v Chief Constable of West Yorkshire, the respondent contended that public policy considerations precluded the imposition of a duty of care in this context. The respondent further argued that imposing liability would risk inhibiting effective policing and lead to defensive decision-making by officers engaged in arrest operations.[8]

Judgement/ Final Decision

The Supreme Court allowed the appeal. It held that the police officers owed Mrs Robinson a duty of care under ordinary principles of negligence. The Court rejected the view that the police enjoy a general immunity from negligence liability when performing their core operational functions of investigating and preventing crime.

The Court further held that the officers’ actions constituted a positive act which created a foreseeable risk of physical injury to nearby pedestrians, and that Mrs Robinson fell within the class of persons to whom the duty was owed. In these circumstances, the principles derived from Hill v Chief Constable of West Yorkshire did not preclude the imposition of liability.

The Supreme Court overturned the decision of the Court of Appeal and restored the Recorder’s finding that the officers were in breach of their duty of care and that the breach caused Mrs Robinson’s injuries. The case was remitted for the assessment of damages.[9]

Legal Reasoning/ Ratio Decidendi

The Supreme Court’s reasoning in Robinson v Chief Constable of West Yorkshire Police centred on a clarification of the correct approach to determining the existence of a duty of care in negligence, particularly in cases involving public authorities. Lord Reed explained that the Court of Appeal had approached the question of duty on an incorrect basis by treating it as one requiring the application of a universal test, rather than by reference to established principles of negligence law.[10]

Rejection of a universal Caparo test

A central aspect of the Court’s reasoning was its rejection of the view that the three-stage test formulated in Caparo Industries plc v Dickman must be applied afresh in every negligence case. Lord Reed explained that this interpretation misunderstood the purpose of Caparo, which was intended to reject the idea of a single general formula for determining duty of care, rather than to create one. Instead, the common law develops incrementally, by analogy with existing categories of liability.[11]

The Court stressed that where the law has already recognised that a duty of care arises in a particular type of situation, such as cases involving physical injury caused by a defendant’s actions, it is unnecessary and inappropriate to re-examine whether it is fair, just and reasonable to impose a duty in each individual case. Considerations of fairness and reasonableness are already embedded within the established principles themselves. Only in genuinely novel cases does the court need to weigh policy considerations more explicitly.[12]

Incremental development and established principles

Applying this approach, the Supreme Court held that the present case did not involve a novel extension of negligence law. The claim concerned personal injury caused by a positive act, a category in which liability has long been recognised. The Court therefore approached the issue by applying orthodox negligence principles, including foreseeability of harm, proximity, and the absence of any recognised exclusionary rule.

By framing the analysis in this way, Lord Reed reinforced legal certainty and coherence, warning that re-deciding duty questions on a case by case basis would risk inconsistency and unpredictability. The Court reaffirmed that negligence law should not be reformulated in each case according to broad appeals to justice or public policy, particularly where established authority already provides an answer.

Police liability and the reinterpretation of Hill

A further key element of the Court’s reasoning concerned the scope and meaning of Hill v Chief Constable of West Yorkshire. The Supreme Court clarified that Hill did not establish a general immunity shielding the police from negligence claims. Rather, it was an omissions case, concerning a failure to prevent harm caused by a third party, and was influenced by policy considerations specific to that context.[13]

In contrast, in Robinson, the police officers were alleged to have caused injury through their own actions. Lord Reed emphasised that where police officers carry out positive acts which foreseeably cause physical harm, they are subject to the same principles of liability as any other defendant. Public policy considerations relating to effective policing could not justify a blanket exclusion of liability in such circumstances.[14]

This reasoning marked a significant correction of how Hill had been understood and applied by lower courts. The Supreme Court made clear that the police are not exempt from the ordinary duty to take reasonable care to avoid causing foreseeable injury when engaging in operational activities.

Acts and omissions

The distinction between acts and omissions played a decisive role in the Court’s analysis. The Supreme Court characterised the attempted arrest as a positive act, rather than a mere failure to protect Mrs Robinson from harm. The officers’ conduct created a foreseeable risk of injury to pedestrians in a busy public street, and Mrs Robinson fell within the class of persons who might reasonably be affected by that risk.

Due to the fact the case involved a positive act, the restrictive principles governing liability for omissions and failures to protect others were inapplicable. Once this classification was established, the imposition of a duty of care followed naturally from ordinary negligence principles.[15]

Ratio decidendi

The ratio decidendi of the case is that police officers owe a duty of care under ordinary principles of negligence when, through positive acts carried out in the course of their duties, they cause foreseeable physical injury to members of the public. The existence of such a duty does not depend on the application of a universal Caparo test, neither is it excluded by general public policy considerations derived from Hill v Chief Constable of West Yorkshire.[16]

Conclusions/Observations

The decision in Robinson v Chief Constable of West Yorkshire Police is significant for its clarification of the correct approach to duty of care in negligence, particularly in cases involving the police and other public authorities. The Supreme Court confirmed that negligence claims should generally be resolved by applying established principles, rather than by treating each case as an opportunity to reconsider whether it is fair or reasonable to impose liability. In doing so, the Court restored doctrinal clarity and corrected a tendency in the lower courts to rely too heavily on broad public policy arguments.

The case is especially important for its clarification of police liability. By explaining that Hill v Chief Constable of West Yorkshire did not create a general immunity, the Supreme Court narrowed the scope of situations in which public policy considerations can exclude liability. The decision draws a clear distinction between cases involving omissions, such as failures to prevent harm caused by third parties, and cases involving positive acts which directly create a foreseeable risk of injury. This distinction aligns Robinson with earlier authority, while also providing clearer guidance for future claims.

Commentary has noted that Robinson represents a shift away from defensive reliance on policy-based reasoning and towards a more principled and structured application of negligence law. By emphasising incremental development and legal certainty, the decision strengthens the coherence of duty of care analysis and limits the risk of inconsistency in future cases involving public authorities. As a result, Robinson is likely to remain a leading authority on police liability and the role of the Caparo framework within modern negligence law.[17]
