Ratio Decidendi
A duty of care in the tort of negligence arises only where three conditions are simultaneously satisfied: (1) the harm caused was a reasonably foreseeable consequence of the defendant's conduct; (2) there was a sufficient relationship of 'proximity' or 'neighbourhood' between the claimant and the defendant; and (3) the court considers it fair, just and reasonable to impose a duty of a given scope in the circumstances. The three-stage test rejected the broader two-stage Anns v Merton London Borough Council [1978] AC 728 approach, and emphasised that novel duties should be developed incrementally and by analogy with established categories. In the specific context of careless statements causing pure economic loss, a duty arises only where the maker of the statement knew or ought to have known that the particular claimant would rely on the statement for a particular purpose, and did so rely.

Caparo Industries plc purchased shares in Fidelity plc, a publicly listed company, relying on the audited annual accounts prepared by the defendants Dickman and Touche Ross (Fidelity's statutory auditors). Caparo first acquired shares in the open market and later launched a successful takeover bid, ultimately acquiring control of Fidelity. The accounts had shown a pre-tax profit of approximately ยฃ1.3 million; the true position was a loss of around ยฃ400,000. Following the takeover Caparo discovered the inaccuracy and sued the auditors in negligence, alleging breach of duty owed to it (a) as an existing shareholder who increased its holding and (b) as a potential takeover bidder. At first instance Sir Neil Lawson held no duty was owed; the Court of Appeal (Bingham and Taylor LJJ, O'Connor LJ dissenting) reversed in part, holding that a duty was owed to Caparo as an existing shareholder; both sides appealed.

The House of Lords (Lord Bridge of Harwich, Lord Roskill, Lord Ackner, Lord Oliver of Aylmerton, and Lord Jauncey of Tullichettle) unanimously allowed the auditors' appeal and held that no duty of care was owed to Caparo, either as existing shareholder or as bidder. Lord Bridge, giving the principal speech, restated the test for duty of care in three stages โ foreseeability, proximity, and the fair-just-reasonable requirement โ and warned that purportedly single general principles in tort (such as the broad neighbourhood principle from Donoghue v Stevenson, or the two-stage Anns test) should be approached with caution. Lord Oliver, in a particularly influential passage, set out the additional features required to establish proximity in cases of negligent misstatement causing pure economic loss: the defendant must know (actually or constructively) that the statement will be communicated to the claimant either as an individual or as a member of an identifiable class; that it will be communicated for a particular purpose; and that the claimant is very likely to rely on it for that purpose. Applying that test, the purpose of the statutory audit under what is now the Companies Act 2006 is to provide shareholders collectively with information enabling them to exercise informed governance rights โ not to provide investment advice to existing shareholders contemplating further purchases or to outside bidders contemplating takeovers. There was therefore insufficient proximity. The three-stage Caparo test has, in the decades since, become the canonical framework for English tort law's analysis of novel duty-of-care situations.

"What emerges is that, in addition to the foreseeability of damage, necessary ingredients in any situation giving rise to a duty of care are that there should exist between the party owing the duty and the party to whom it is owed a relationship characterised by the law as one of 'proximity' or 'neighbourhood' and that the situation should be one in which the court considers it fair, just and reasonable that the law should impose a duty of a given scope upon the one party for the benefit of the other."

"The law has now moved in the direction of attaching greater significance to the more traditional categorisation of distinct and recognisable situations as guides to the existence, the scope and the limits of the varied duties of care which the law imposes."
โ Lord Bridge at 618
"In the end, it has to be accepted that the concept of 'proximity' is an artificial one which depends more upon the court's perception of what is the reasonable area for the imposition of liability than upon any logical process of analogical deduction."

"The purpose for which the auditors' certificate is made and published is that of providing those entitled to receive the report with information to enable them to exercise in conjunction those powers which their respective proprietary interests confer upon them and not for the purposes of individual speculation with a view to profit."

Remains the canonical authority on duty of care in English negligence law. The three-stage Caparo test was treated as the default analytical framework for over 25 years.
In Robinson v Chief Constable of West Yorkshire Police [2018] UKSC 4, [2018] AC 736 Lord Reed re-characterised the Caparo test: it should not be applied as a single tri-partite framework to every new case, but rather courts should first ask whether the claim falls within an established category of duty; the full Caparo analysis applies only where the case is genuinely novel. This is a significant clarification but does not displace the test for novel duty cases.
Applied to extend duties of care in NHS Trust Development Authority v Foster [2017] EWHC 2503 (QB) (regulatory references); in JCP Solicitors Ltd v Aslam [2024] EWHC 132 (KB) (solicitor advice). Restrictively applied in Mitchell v Glasgow City Council [2009] UKHL 11 (police liability).
In professional-negligence cases involving pure economic loss, the more specific test from Hedley Byrne & Co Ltd v Heller & Partners Ltd [1964] AC 465, refined by Lord Oliver in Caparo itself and again by Lord Goff in Henderson v Merrett Syndicates [1994] UKHL 5, often supplies the practical answer โ the Caparo three-stage test is then merely a back-stop.
