Swinney & Anor v Chief Constable of Northumbria Police Force

Factual and Procedural Background

The Plaintiffs, husband and wife tenants of a public house in The City, provided sensitive information to the police about a criminal responsible for a fatal incident involving a police officer. The first Plaintiff gave this information in confidence to a police officer, who recorded it on a document. The document was negligently left in an unattended police vehicle, which was then broken into by criminals who obtained the information, leading to threats and psychiatric damage to the Plaintiffs.

The Plaintiffs brought a claim against the Defendant, the Chief Constable of the local police force, alleging negligence and breach of confidence. The Defendant sought to strike out the claim on grounds that no reasonable cause of action existed, invoking principles of duty of care and public policy immunity for police actions. The case proceeded through interlocutory stages, including an application to amend the Statement of Claim to add a cause of action for breach of confidence after the limitation period had expired.

The appeal before the court challenged an order allowing the Plaintiffs' appeal against a previous striking out of their claim. The court was tasked with assessing the existence of a duty of care owed by the police to the Plaintiffs, the applicability of public policy immunity, and the permissibility of the proposed amendment to the Statement of Claim.

Legal Issues Presented

1. Whether the Plaintiffs have established a special relationship of proximity with the Defendant police force sufficient to found a duty of care in negligence.
2. Whether public policy principles, including police immunity, preclude the Plaintiffs' claim in negligence for the alleged negligent disclosure of confidential information.
3. Whether the Court should grant leave to amend the Statement of Claim to add a cause of action for breach of confidence despite the expiry of the limitation period.
4. Whether a cause of action for breach of confidence exists in circumstances of negligent disclosure of information to the police absent a contractual relationship.

Arguments of the Parties

Appellant's Arguments

• The Plaintiffs argue that the information was given in confidence, creating either an express or implied duty of confidentiality owed by the Defendant and their officers.
• The proposed amendment to add breach of confidence is supported by established authority, notably Attorney-General -v- Guardian Newspapers (No 2), which recognizes a duty of confidence and remedies for breach, including damages for negligent breaches.
• They submit that the police owed a duty of care due to a special relationship arising from the sensitive nature of the information and foreseeable harm if disclosed.
• They contend that public policy considerations support their claim, particularly the need to protect informants to encourage the flow of information to the police, outweighing general police immunity.
• The Plaintiffs maintain that the case is at least arguable on both proximity and public policy grounds, warranting trial and the granting of leave to amend.

Appellee's Arguments

• The Defendant accepts the Court's discretion to allow amendment but resists it as a late attempt to reframe existing negligence allegations without adding substantive new cause of action.
• They argue that the cause of action for breach of confidence in negligent disclosure absent contractual relationship is doubtful, relying on the Law Commission's report and precedent such as Weld-Blundell -v- Stephens.
• On duty of care, the Defendant asserts there is no special relationship of proximity distinguishing the Plaintiffs from the general public, likening the case to Hill -v- Chief Constable of West Yorkshire and Alexandrou -v- Oxford where no duty was found.
• They invoke public policy immunity for police negligence in investigation and suppression of crime, emphasizing the risk of defensive policing and diversion of resources if liability were imposed.
• The Defendant contends that only deliberate disclosure of confidential information would negate immunity, and negligent disclosure remains protected.
• They deny any assumption of responsibility by the police to the Plaintiffs, arguing the police were mere recipients of information without a duty beyond general public protection.

Court's Reasoning and Analysis

The Court carefully examined the facts as pleaded, treating them as true for the purpose of the appeal against striking out. It identified that the Plaintiffs, as informants, provided sensitive information in confidence to the police, which was negligently disclosed due to improper storage of the document. The Court considered established principles on duty of care requiring a special relationship of proximity, concluding that the Plaintiffs were distinguishable from the general public due to the confidential nature of the information and the foreseeable risk of harm if disclosed.

The Court analyzed relevant precedent distinguishing cases where no special relationship existed, such as Hill and Alexandrou, but found that the confidentiality element and specific risk to the Plaintiffs placed this case within the Dorset Yacht category where a duty may exist. It acknowledged the strong public policy arguments in Hill for police immunity to avoid defensive policing and resource diversion, but balanced these against the public interest in protecting informants and encouraging information flow to the police.

The Court further considered whether a cause of action for breach of confidence could be added despite the limitation period. It found the amendment arguable and justified under the Court's discretion to allow amendments arising from the same facts. The Court noted legal uncertainty but recognized that negligent breach of confidence is supported by authority and should be tested at trial.

Overall, the Court concluded that the Plaintiffs' claims were at least arguable on both duty of care and breach of confidence grounds, and that public policy considerations did not conclusively bar the claims. It emphasized that the ultimate success depended on evidence at trial, not on the pleadings stage.

Holding and Implications

The Court DISMISSED THE APPEAL, thereby affirming the order allowing the Plaintiffs' claim to proceed and granting leave to amend the Statement of Claim to include breach of confidence.

This decision permits the Plaintiffs to pursue their claims on the merits at trial, including the newly added cause of action. It confirms that police immunity in negligence is not absolute and may be rebutted where a special relationship and assumption of responsibility exist, particularly in cases involving confidential informants. The ruling emphasizes the need to balance public policy considerations carefully and leaves open the question of ultimate liability for trial. No new binding precedent was established beyond affirming the arguability of the claims in these circumstances.
