Chief Constable of Northumbria v Costello
Factual and Procedural Background
On 24 April 1992, the Plaintiff, a woman Police Constable serving in the Northumbria Police, was attacked and injured by a woman prisoner in a cell at South Shields Police Station. Inspector Bell was nearby but did not assist the Plaintiff during the attack. The Plaintiff brought proceedings against the Chief Constable of Northumbria, alleging that her injuries were caused by the negligence of Inspector Bell or the Chief Constable himself. The Plaintiff's claim asserted that Inspector Bell owed her a duty of care to come to her assistance and prevent injury, and that the Chief Constable was liable for Inspector Bell's failure under Section 48 of the Police Act 1964. The claim also alleged that the Chief Constable breached a duty to provide a safe system of work by failing to provide physical assistance. The Chief Constable denied owing a duty of care and alternatively claimed immunity.
The High Court, before Judge Astill, found in favour of the Plaintiff on duty and breach of duty issues. The Chief Constable appealed, contending that no duty of care was owed by one police constable to another to provide assistance when attacked.
Legal Issues Presented
- Whether a police constable owes a duty of care to another police constable to provide assistance if the latter is attacked.
- Whether the Chief Constable is vicariously or personally liable for breach of such a duty.
- Whether public policy considerations preclude imposing such a duty of care on police officers or their superiors.
Arguments of the Parties
Appellant's Arguments
- The judge erred in imposing a positive duty on a police constable to act in circumstances that might endanger the constable himself.
- The common law generally does not impose liability for omissions except in exceptional circumstances involving a special relationship.
- Police are immune from negligence claims for their operational activities in crime investigation and suppression, as established in Hill v. Chief Constable of West Yorkshire.
- Even if a special relationship existed, public policy dictates that police immunity should apply to prevent liability for operational decisions.
- The courts are not the proper forum to adjudicate operational decisions made in the heat of the moment, which are better regulated internally by police disciplinary regulations.
- Compensation is available through other means such as the Criminal Injuries Compensation Board and ill health retirement schemes, reducing the need for tort liability.
- Imposing such a duty risks police morale, drains police resources, and opens floodgates to litigation.
Appellee's Arguments
- The relationship between the Chief Constable and the Plaintiff is analogous to employer and employee, imposing a duty to take reasonable care to avoid exposing the Plaintiff to unnecessary risk.
- The system of work required two officers to be present with a potentially dangerous prisoner; Inspector Bell negligently failed to fulfill his part, causing unnecessary risk.
- The Chief Constable is liable for the failure of his subordinate under vicarious liability principles.
- Analogies with other workplace safety scenarios demonstrate that an employer is liable when an employee fails to perform duties that ensure safety of another employee.
- There is no sound policy distinction between such examples and the present case.

Court's Reasoning and Analysis
The court analysed the duty of care by applying the established three-fold test from Caparo Industries v. Dickman: foreseeability of damage, proximity of relationship, and whether it is just and reasonable to impose a duty. It found that the Plaintiff’s injuries were foreseeable and that a sufficiently close relationship existed between the Plaintiff and Inspector Bell, who had assumed responsibility to assist if needed. The Chief Constable, through Inspector Bell, also assumed this responsibility.
The critical issue was whether it was just and reasonable, considering public policy, to impose a duty of care in these operational circumstances. The court reviewed relevant authorities on police immunity and public rescue services, noting that while police generally enjoy immunity from negligence claims in crime investigation and suppression, this immunity is not absolute.
The court distinguished the present case by the extraordinary facts: Inspector Bell acknowledged a duty to assist but deliberately failed to act when the Plaintiff was attacked, exposing her to unnecessary risk. This constituted a breach of a specific police duty, which the court incrementally recognized as a legal duty of care actionable in tort. The court emphasized that the relationship between police officers working together is closer than between police and the public, justifying this incremental step.
The court balanced public policy concerns, including the need to avoid litigation over operational decisions made in dangerous moments, against the common sense and public perception that police officers should be personally liable for deliberate failures to assist colleagues when a duty is acknowledged. The court rejected the appellant’s floodgates argument and the availability of alternative compensation as sufficient reasons to deny a duty of care.
It concluded that while no general duty arises for operational omissions, the specific circumstances here—an acknowledged duty and deliberate inaction—gave rise to a breach of legal duty. The Chief Constable was vicariously liable for Inspector Bell’s breach but was not personally in breach.
Holding and Implications
The court DISMISSED THE APPEAL.
The holding establishes that a police officer may owe a duty of care to a fellow officer in operational circumstances where the assisting officer acknowledges a duty and deliberately fails to act, exposing the colleague to unnecessary risk of injury. The Chief Constable is vicariously liable for such breach by a subordinate.
This decision does not create a broad new duty of care for all operational omissions by police officers but recognizes a limited incremental exception. It preserves the general principle of police immunity for operational decisions while allowing civil redress where a specific police duty is acknowledged and deliberately breached. The ruling aligns legal responsibility with public expectations of police conduct and does not undermine established public policy considerations limiting police liability.
