Donoghue v. Stevenson

A decomposed snail in an opaque ginger-beer bottle, and a friend who had no contract with the manufacturer at all, produced the single most quoted sentence in the entire common law of negligence — the "neighbour principle" that decides, to this day, who owes a duty of care to whom.

Parties

May Donoghue — pursuer (the Scottish term for plaintiff); the consumer who became ill.

David Stevenson — defender (defendant); the manufacturer of the ginger beer.

Facts

On the evening of 26 August 1928, during the Glasgow Trades Holiday, May Donoghue travelled to Paisley and went with a friend to the Wellmeadow Café. Her friend bought her a "Scotsman" — a mixture of ice cream and ginger beer. The café owner, Francis Minghella, poured ginger beer from a dark, opaque bottle labelled "D. Stevenson, Glen Lane, Paisley" over ice cream in a tumbler.

Donoghue drank some of the mixture. When the remainder of the ginger beer was poured out to refill her glass, the decomposed remains of a snail floated out of the bottle. Because the bottle was made of dark, opaque glass, its contents could not have been seen before this point. Donoghue alleged that she suffered shock and severe gastroenteritis as a result of what she had already consumed, combined with the sight of the snail.

Because it was Donoghue's friend, not Donoghue herself, who had purchased the ginger beer, Donoghue had no contract with either the café owner or Stevenson, the manufacturer. She could not sue in contract, and instead sued Stevenson directly in negligence — a claim that, at the time, had no clear, settled precedent supporting a manufacturer's direct duty to an ultimate consumer with whom the manufacturer had no contractual relationship at all.

Issues Raised

1. In the absence of any contract between a manufacturer and the ultimate consumer of its product, can the manufacturer nonetheless owe that consumer a duty of care in negligence?
2. If such a duty can exist, what general principle determines when one person owes a duty of care to another, beyond the specific facts of manufactured products?

Arguments Contended

On behalf of Donoghue (Pursuer): Donoghue argued that a manufacturer who puts a product into circulation in a sealed, opaque container, intended to reach the ultimate consumer in the same form in which it left the manufacturer without any realistic possibility of inspection along the way, owes that consumer a duty to take reasonable care that the product is free from defects likely to cause injury. The absence of a contract between her and Stevenson should not bar a remedy, since the whole point of a sealed, opaque bottle was that no one — neither the retailer nor the consumer — could realistically inspect its contents before use.

On behalf of Stevenson (Defender): Stevenson's position rested on the traditional, narrower understanding of negligence liability, which at the time was generally understood to require either a contractual relationship or some other specific, previously recognised category of relationship between the parties (such as that established in earlier product-related cases involving inherently dangerous articles). Since Donoghue had no contract with Stevenson at all, and her case did not fit any previously recognised specific category in which a duty of care had been held to exist, there was, on the existing state of the law, no basis to impose liability on a manufacturer towards a consumer with whom it had no direct dealing.

Court's Reasoning

The House of Lords, by a narrow majority of three to two (Lord Atkin, Lord Thankerton and Lord Macmillan in the majority; Lord Buckmaster and Lord Tomlin dissenting), held that a manufacturer of products which it sells in a form intended to reach the ultimate consumer without any reasonable possibility of intermediate examination owes that consumer a duty to take reasonable care that the product is free from defects likely to cause injury.

Lord Atkin's leading judgment went further than deciding the narrow point about manufacturers, formulating what became known as the "neighbour principle": a person must take reasonable care to avoid acts or omissions which they can reasonably foresee would be likely to injure their "neighbour" — defined as persons so closely and directly affected by the act that the person ought reasonably to have them in contemplation as being so affected, when directing their mind to the acts or omissions in question. This reasoning broke decisively from the earlier, narrower position that had generally required either a contract or a specific, previously recognised category of relationship before a duty of care could arise, establishing instead a general, principled basis for a duty of care capable of extending well beyond the particular manufacturer-consumer relationship at issue in the case itself.

Lord Buckmaster and Lord Tomlin, dissenting, took the view that extending liability this far, without either a contract or a previously recognised specific duty, went beyond the proper, incremental development of the law and risked opening liability too broadly and uncertainly.

Judgement

By a 3–2 majority, the House of Lords held that Stevenson owed Donoghue a duty of care as the ultimate consumer of his product, and that she had an actionable claim in negligence against him despite having no contract with him. Because this was an appeal on a preliminary point of law (whether Donoghue's pleadings disclosed a valid cause of action at all), the case was sent back for trial on the facts — but before it could be tried, it was settled out of court in December 1934, reportedly for £200 of the £500 originally claimed.

Legal Principle / Ratio

A manufacturer of products which it sells in a form intended to reach the ultimate consumer, without any reasonable possibility of intermediate examination, owes that consumer a duty to take reasonable care that the product is free from defects likely to cause injury. More generally, a person owes a duty of care to their "neighbour" — anyone so closely and directly affected by their acts or omissions that they ought reasonably to have that person in contemplation as being so affected — laying down a general, foreseeability-based test for the existence of a duty of care in negligence.

Significance

Donoghue v. Stevenson is the foundational authority for the modern law of negligence, and Lord Atkin's neighbour principle remains the starting point for determining when a duty of care arises in any negligence claim, in England, India, and across the common law world. It established that a manufacturer's responsibility for the safety of its products runs directly to the ultimate consumer, independent of the chain of contracts through which the product actually reached them — a principle now fundamental to product liability law generally, and the single most cited starting point in negligence law for over ninety years since it was decided.

Exam-Important Points

• Facts in one line: a decomposed snail was found in an opaque bottle of ginger beer after Donoghue had already drunk part of it; she had no contract with the manufacturer, Stevenson, since her friend had bought it.
• Holding: by a 3–2 majority, Stevenson owed Donoghue a duty of care as ultimate consumer, despite no contract between them.
• Lord Atkin's "neighbour principle": take reasonable care to avoid acts/omissions reasonably foreseeable to injure persons so closely and directly affected that they ought to be in your contemplation.
• Dissent to remember: Lord Buckmaster and Lord Tomlin dissented, viewing this as too broad an extension of liability without a contract or prior recognised category.
• Real-world footnote: the case never actually went to trial on the facts — it settled out of court in December 1934, for £200 of the original £500 claim.
• This is the single most foundational case in negligence law — the starting point for "duty of care" in virtually every jurisdiction that follows English common law.
