(1842) 10 M. & W. 109, 152 Eng. Rep. 402 (Exch.)
Winterbottom v. Wright is a foundational nineteenth-century English tort decision that drew a bright line between contract and tort, insisting that negligence liability ordinarily does not extend beyond the parties in privity with a contract.
Does a contractor who agrees with one party to maintain a chattel owe a duty in tort to a third person, not in privity of contract, who is injured by the contractor's negligent performance of that agreement?
As a general rule, negligence liability does not extend to third parties who lack privity with the defendant's contract. Absent privity—or special circumstances such as fraud, an inherently or imminently dangerous instrumentality, or a public duty/nuisance—no action in tort lies against a contractor for negligent performance causing injury to a non-party to the contract.
No. The contractor owed no actionable duty in tort to the plaintiff driver, a stranger to the contract. Judgment for the defendant.
Winterbottom entrenched the privity requirement as a barrier to third-party negligence claims arising from contractual undertakings, particularly in early products and services cases. It is the starting point for understanding the historical limits of duty in tort and the policy fears of boundless liability. The case was progressively confined and then largely superseded by decisions expanding duty beyond privity—most notably Thomas v. Winchester (dangerous products), MacPherson v. Buick Motor Co. (foreseeability-based manufacturer's duty), and, in the UK, Donoghue v. Stevenson (general neighbor principle). For students, Winterbottom illuminates the evolution from strict privity toward modern notions of foreseeability, risk, and enterprise responsibility, as well as the interplay between contractual allocation of risk and tort-based protection of physical safety.
