The Snail in the Ginger Beer

Donoghue v. Stevenson and the Duty of Care to Strangers

Inside the Wellmeadow Café at 1 Wellmeadow Place in Paisley, Scotland, on the evening of August 26, 1928, a Glasgow shop assistant named May Donoghue sat down at a table with a friend. The friend ordered a pear and ice for herself and a Scotsman ice-cream float for Donoghue, and the café proprietor, Francis Minghella, brought a glass tumbler containing vanilla ice cream to the table along with a sealed bottle of ginger beer manufactured by local Paisley bottler David Stevenson. The bottle was cast from dark opaque brown glass, sealed at the neck with a metal crown cap, and pasted with a paper label reading D. Stevenson, Glen Lane, Paisley.

Minghella pried off the metal cap and poured half of the fizzy ginger beer over the ice cream. Donoghue drank several mouthfuls. When her friend picked up the dark brown bottle to top up the tumbler, the decomposing corpse of a garden snail floated out of the bottle neck into the glass. Shocked by the sight and having swallowed the contaminated liquid from the first pour, Donoghue suffered severe gastro-enteritis requiring outpatient treatment at the Glasgow Royal Infirmary and three weeks off work.

When Donoghue consulted Glasgow solicitor Walter Leechman, existing British law offered her zero legal remedy against anyone. Under the Sale of Goods Act 1893, a buyer injured by unmerchantable drink could sue the café owner for breach of an implied contractual warranty—but May Donoghue had not bought the ginger beer. Her friend had ordered and paid for it, meaning Donoghue had no contract with Minghella. Nor could her friend sue for damages, because the friend had not drunk the ginger beer. Even if Donoghue had paid Minghella herself, Minghella had not been negligent: the bottle arrived sealed in dark opaque glass from Stevenson's factory, making it impossible for a café keeper to inspect the interior before opening.

That left the manufacturer, David Stevenson, whose back-lane washhouse stacked empty returned bottles in an open courtyard where snails crept inside before the filling machines capped them. Yet for ninety years, courts had shielded manufacturers behind the fortress wall of privity of contract, forged by the Court of Exchequer in the 1842 stagecoach decision Winterbottom v. Wright. In Winterbottom, a mail-coach driver crippled when a defective wheel collapsed tried to sue the contractor who had promised the Postmaster General to keep the coach in repair. Lord Abinger threw out the lawsuit, warning that if a stranger who was not a party to a contract could sue for its negligent performance, manufacturers would face absurd and outrageous liabilities without any foreseeable limit.

Under the nineteenth-century privity rule, because David Stevenson had sold the ginger beer to a distributor or to Minghella—and had no contract with May Donoghue—Stevenson owed her no legal duty of care, unless the product belonged to a narrow list of intrinsically dangerous items like loaded guns or poison. When the Scottish Second Division dismissed Donoghue's 500-pound claim on the strength of Winterbottom precedent, Leechman took her case to the House of Lords in London as a pauper appeal.

On May 26, 1932, by a 3-to-2 majority in Donoghue v. Stevenson, Lord Atkin delivered a speech that demolished the privity wall and invented the modern law of negligence and product liability. Drawing on the parable of the Good Samaritan—where a lawyer asks "Who is my neighbour?"—Atkin translated moral responsibility into a four-part legal rule for an economy of sealed mass production:

• * The General Neighbor 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 in law as any persons so closely and directly affected by the act that the actor ought reasonably to have them in contemplation.
• * Severance of Tort Duty from Contract Privity: A duty of care in tort arises independently by operation of law rather than private contract; a manufacturer's sales contract with a middleman wholesaler does not immunize the manufacturer from tort liability to a third-party stranger injured by a negligently made product.
• * The Sealed-Channel Trigger: Whenever a manufacturer sells goods in a form (such as an opaque sealed bottle or soldered tin can) intended to reach the ultimate consumer without any reasonable possibility of intermediate inspection by a retailer or buyer, legal proximity links the factory floor directly to the consumer.
• * Direct Manufacturer Liability: A manufacturer who breaches that duty by allowing latent defects into the sealed container is liable to the ultimate consumer for resulting injury to life, health, or property, regardless of how many distributors or gift-givers stood in between.

David Stevenson died before the factual trial could occur, and his estate settled May Donoghue's claim for 200 pounds. In 1990, legal scholars from Britain, Canada, and the Commonwealth gathered in Paisley to unveil a bronze memorial plaque on the site of the Wellmeadow Café, honoring the decomposed snail that created modern consumer protection and product liability law.
