The Snail in the Bottle

A woman in Paisley drank a bottle of ginger beer she had not paid for — and modern liability was invented to give her a remedy.

Today: you'll work through the case that created the modern duty of care — and you'll sharpen the language lawyers use to define exactly who a rule catches and who it lets go: any person who…, such goods as…, in circumstances in which…, to whom the duty is owed.
Before we start. Talk these through out loud.
Discuss:
  • Think of something you have bought that was faulty. Who did you complain to — the shop or the maker? Why that one?
  • You are harmed by a product you did not buy: a gift, a free sample, something served to you. Should that change what you can recover, and why?
  • In your working life, where does your organisation's responsibility stop? Say who draws that line — a contract, a statute, a policy, or nobody in particular.

The vocabulary of this case

Ten items. Work through the four activities — say your answer out loud before you reveal it.

A · What do they mean here? Work it out from the context

1. Nobody suggested the manufacturer had wanted anyone to be harmed. The claim was that he had failed to keep his bottling plant clean, and that this careless failure caused the illness — in short, negligence.
negligence (n, uncountable) — a failure to take the care the law requires, causing harm. Note it is not about intention. Adjective negligent, adverb negligently. Collocations: gross negligence, an action in negligence, negligent misstatement.
2. Her friend had paid for the drink, so the agreement was between her friend and the café owner. Mrs Donoghue stood outside that agreement entirely — and under the rule of privity of contract, that was fatal to any claim in contract.
privity of contract (n) — the principle that only the parties to a contract can sue on it. Third parties, however badly affected, have no standing under it. Still the default rule in most systems, now softened by statute in several.
3. A bottler who leaves a plant open to vermin does not know who will be harmed, or when. But he can perfectly well see that somebody drinking his product might be. That kind of harm is foreseeable.
foreseeable (adj) — such that a reasonable person could have anticipated it. Noun foreseeability; the test is objective, not "did you foresee it?" but "should you have?". Collocations: reasonably foreseeable, foreseeable loss.

B · Which term means…?

Three terms: liability · damages · precedent. Say the right one, then reveal.

1. Which noun means legal responsibility for something, and therefore exposure to being made to pay for it?
liability (n) — "The manufacturer denied liability." Adjective liable: liable for the loss, liable to a fine. Useful compounds: strict liability (no fault needed), joint and several liability, to limit / exclude liability.
2. Which noun means the money a court orders one party to pay another to compensate for a loss?
damages (n, plural — never "a damage") — to claim / award / recover damages. Distinguish damage (uncountable: the harm itself). Types: general, special, nominal, punitive / exemplary.
3. Which noun means an earlier decision that later courts must, or may, follow?
a precedent (n) — binding on lower courts, persuasive otherwise. The doctrine is stare decisis. Verbs to collect: to set a precedent, to follow, to distinguish (say it doesn't apply here), to overrule (kill it).

C · Choose the meaning — a / b / c

1. The judges in the minority warned that if a duty were owed to everyone a product might reach, the courts would be buried in claims from strangers. This is the floodgates argument. It means…
  (a) that the decision would be too expensive for the defendant   (b) that recognising the rule would open the way to an unmanageable volume of future claims   (c) that the harm was caused by water damage
(b) — the floodgates argument: "to open the floodgates to litigation". It is an argument about consequences rather than principle, which is exactly why it is both powerful and suspect. Still made in every novel-duty case.
2. Lawyers reading a judgment separate the reasoning essential to the result from the judge's other observations. The essential part is the ratio; anything said in passing is obiter. To identify the ratio is to identify…
  (a) the amount awarded   (b) the proportion of judges who agreed   (c) the legal reason for the decision, which binds later courts
(c) — the ratio (full form ratio decidendi, "the reason for deciding"). Contrast obiter dicta, persuasive only. Half of common-law argument is a fight about how wide or narrow the ratio of a famous case really is — as you'll see today.

D · Collocation & word building

1. Complete the phrase at the centre of this case: before you can be liable in negligence, you must first owe the other person a duty of ___. Complete it, then say the whole verb phrase for what a defendant does with that duty when they fail.
a duty of care — to owe a duty of care to someone; when you fail, you breach it: to breach / be in breach of a duty. The full chain a claimant must prove: duty → breach → causation → damage. Learn it as a sequence; it is the skeleton of every negligence argument.
2. Two of the five judges disagreed with the result and wrote separately. Complete the term for such a judgment — a ___ judgment — and give the verb and the noun for the judge's act.
a dissenting judgment (US: a dissenting opinion). Verb: to dissent (Lord Buckmaster dissented); noun: a dissent. The opposite is a concurring judgment — same result, different reasoning. Dissents matter: they are often the argument that wins forty years later.

Now use them — out loud

Before we read:
  • Using privity of contract, foreseeable, duty of care and floodgates, predict the argument each side made when a woman with no contract sued a manufacturer she had never dealt with.
  • Which of these terms would you put in a written submission, which in an email to a client, and which only in conversation? Sort them out loud, and say what you would use instead in the plainest version.

The case, in three parts

Read each part. After it, there's a quick check (answer from memory first), then one question to discuss.

Part 1 — Paisley, a Sunday evening in August

On the evening of 26 August 1928, May Donoghue took the tram from Glasgow to Paisley and went into the Wellmeadow Café with a friend. She was a shop assistant, separated from her husband, and not well off. The friend ordered and paid: an ice cream for Mrs Donoghue, with a bottle of ginger beer to pour over it.

The bottle was dark, opaque glass — you could not see through it, which is the detail the whole case turns on. The café owner poured some over the ice cream. Mrs Donoghue drank it. Then her friend poured out the rest, and, according to the account she later gave, the decomposed remains of a snail came out with it. She said she was made ill: shock, and gastroenteritis serious enough to send her to the Glasgow Royal Infirmary.

She wanted a remedy, and here she ran straight into a wall. She had no contract with anybody. Her friend had bought the drink, so any contract was between the friend and the café owner, and under the doctrine of privity, a stranger to a contract cannot sue on it. She could not sue the café owner, who had sold her nothing and could not have inspected a sealed opaque bottle in any event. That left one target: David Stevenson, the man whose name was on the bottle, who manufactured ginger beer a few streets away — and to whom she was a complete stranger.

Quick check — from memory, then reveal:

1. Why could Mrs Donoghue not sue in contract, and who could have?

2. Why does it matter so much that the bottle was made of dark, opaque glass?

1. She had no contract with anyone: her friend bought the drink. Under privity of contract only a party to the contract can sue on it, so the friend — who suffered no harm — held the only contractual claim, and Mrs Donoghue — who suffered the harm — held none.

2. Because nobody between the factory and her lips could have discovered the problem. The bottle was sealed and you could not see into it, so there was no realistic opportunity for intermediate examination by the retailer or the consumer — which is precisely the situation the eventual rule was built to cover.

Discuss:
  • The person who was harmed had no claim; the person who had a claim was not harmed. Where else in your working life does a right sit with someone other than the person actually affected?

Part 2 — The wall, and the argument against it

The law she was arguing against was almost a century old and had been stated with confidence. In 1842, in a case about a mail coach that collapsed and injured its driver, the courts had held that a person who was not party to the contract of repair could not sue on it — and if the rule were otherwise, one judge had warned, there would be no limit to the actions that might follow. Around this hard rule the courts had allowed only narrow exceptions: things dangerous in themselves, such as guns or poisons, and cases of outright fraud. Ginger beer was not a gun.

Her counsel, Walter Leechman, had already been running similar snail-in-a-bottle claims and losing. But he framed this one to reach the general question rather than the exceptions: did a manufacturer owe a duty, independent of any contract, to the person who would ultimately consume the product? The case went up on that point of law alone — not on the facts, which were never tried. Formally, everyone argued as if the snail were there, to see whether, if it were, she had any claim at all.

It reached the House of Lords, then the final court for Scotland as well as England, in December 1931. Mrs Donoghue proceeded as a pauper, which required her to swear that she was not worth £5 in the world apart from her clothing and the subject of the action. Both sides knew what was really at stake: not one bottle, but whether a manufacturer's responsibility ran to the millions of people who would open its sealed products in the years to come.

Quick check — from memory, then reveal:

1. What was the rule she had to overcome, and what exceptions already existed?

2. Why is it significant that the facts of the case were never actually tried?

1. That liability for defective goods ran through contract only, so a person outside the contract had no claim (the 1842 mail-coach rule). The exceptions were narrow: articles dangerous in themselves, and fraud.

2. Because the House of Lords was deciding a pure question of law: assuming the snail was in the bottle, is there a claim? It means the famous case rests on facts nobody ever proved — and that the rule it produced was designed in the abstract, for every future case rather than this one.

Discuss:
  • A rule made in the abstract will govern situations nobody imagined when it was written. Is that a strength or a weakness — and which of your own policies or contract templates has that problem right now?

Part 3 — "Who, then, in law, is my neighbour?"

On 26 May 1932 the House of Lords decided for Mrs Donoghue, by three to two. The leading judgment was Lord Atkin's, and its most quoted sentence is a question: "Who, then, in law, is my neighbour?" His answer was a definition — persons so closely and directly affected by what I do that I ought reasonably to have them in contemplation when I act. Take reasonable care, he said, to avoid acts or omissions you can reasonably foresee are likely to injure such a person.

That is the wide principle. Alongside it he stated a narrow one, and the difference between them has kept lawyers employed for ninety years: a manufacturer who sells products in a form showing that he intends them to reach the ultimate consumer in the state in which they left him, with no reasonable possibility of intermediate examination, owes that consumer a duty to take reasonable care. Every clause in that sentence is doing work — and every clause has been fought over since.

The two dissenters were not being obtuse. Lord Buckmaster argued that the authorities were against it, that the exceptions were narrow for good reason, and that a general principle of this kind had no natural stopping point: if it applies to ginger beer, why not to the builder of a house, or the repairer of a car, and to whom exactly does it not apply? Certainty in commerce, he thought, was worth more than a remedy in a hard case, and any change of this size belonged to Parliament rather than to five judges. That argument lost, and it has never quite gone away.

The rest is smaller than the principle. David Stevenson died later that year; the case settled in 1934, reportedly for around £200, and never came to trial. Nobody ever established that there was a snail. May Donoghue went back to Glasgow, worked, and died in 1958, largely unaware that she had become the most cited claimant in the common-law world.

Quick check — from memory, then reveal:

1. State the neighbour principle in your own words, and then the narrow manufacturer rule.

2. What was the dissent's strongest point — put it as strongly as you can?

1. Wide: you must take reasonable care to avoid acts or omissions you can reasonably foresee would be likely to injure people so closely and directly affected by your conduct that you ought to have them in mind. Narrow: a manufacturer who puts goods out in sealed form, intending them to reach the consumer unexamined, owes that consumer reasonable care.

2. That the new principle had no natural boundary. Once duty is defined by foreseeability, the class of people who can sue you is limited only by imagination — bad for certainty, and a change of that magnitude was a matter for legislation, not for a court deciding a case about a bottle.

Discuss:
  • The wide principle and the narrow rule appear in the same judgment. If you were advising a manufacturer in 1933, which one would you tell them they were now living under — and what would you have them change on Monday morning?

Defining who is covered

Lord Atkin's famous sentence is not a piece of rhetoric. It is a definition, and it is built almost entirely out of relative clauses. This is the single most useful structure in legal English: it is how you say precisely who a rule catches, and — just as importantly — who it lets go.

Defining or non-defining? The commas change the liability.
• "A manufacturer who seals his product in an opaque bottle owes a duty to the consumer." — defining. The clause limits the class: only those manufacturers.
• "A manufacturer, who seals his product in an opaque bottle, owes a duty to the consumer." — non-defining. The clause merely describes: now every manufacturer owes the duty, and the sealing is incidental.

Two commas can widen a rule from a category to the whole world. In drafting, this is not a punctuation preference; it is the scope of the obligation. Note also that that is available for defining clauses only — never after a comma.
The toolkit for drawing the line:
• Opening the class: any person who… · a person to whom… · such goods as… · whoever…
• Preposition + relative (formal, and the standard register in judgments and drafting): "the consumer to whom the duty is owed" · "the circumstances in which the goods were sold" · "the form in which they left him". Compare the conversational version: "the consumer the duty is owed to."
• Reduced relatives — the clause with the pronoun and verb removed, which is how judgments stay readable: "goods sold in sealed containers" (= which are sold) · "a person injured by a defective product" (= who is injured) · "anyone intending to rely on the statement" (= who intends).
• Narrowing devices stacked after the noun: "a manufacturer who sells goods in such a form that they reach the consumer with no reasonable possibility of intermediate examination". Each addition removes people from the class.
• Whose for the possessive link: "a supplier whose labelling omits an allergen".
The reverse skill, equally important: knowing when to stop defining. A definition that keeps adding clauses eventually protects nobody, because no real situation matches it. Lord Atkin's wide principle survived precisely because it was short. When you advise a client, you will often have to say the wide version out loud first — "broadly, you owe a duty to anyone your product can foreseeably reach" — and only then narrow it.

1. Defining or non-defining?

Each pair of sentences is about an e-scooter hire company. Decide which version limits the class, and write in the missing punctuation choice: write commas or no commas, and then say what changes.

1. Intended meaning: only the scooters with worn brakes are covered. → "A scooter whose brakes are worn must be withdrawn from the fleet."

2. Intended meaning: every rider is covered; the helmet detail is extra information. → "The rider who is given a helmet at collection is owed a duty of care."

3. Intended meaning: only the riders who were never told the scooter had been repaired. → "Riders were not informed of the repair may have a claim." (relative pronoun)

1. no commas / no commas   2. commas / commas   3. who (or that)

Read 2 again without the commas: it would mean that only riders who were handed a helmet are owed a duty — and the company has just written itself a defence against every rider who wasn't.

2. Build the rule

A food delivery platform is drafting the clause that decides who it is responsible to. Complete each gap with a relative structure — one or two words.

1. "This policy applies to any customer receives a meal prepared by a partner restaurant." (subject relative)

2. "The duty is owed to the person the meal is delivered, whether or not that person placed the order." (preposition + relative — two words)

3. "The platform is not liable for meals in a manner permitting inspection before consumption." (reduced relative — past participle)

4. "A partner restaurant kitchen has failed an inspection shall be suspended from the platform." (possessive relative)

5. "This clause does not apply in circumstances the customer has altered the product after delivery." (preposition + relative — two words)

1. who / that   2. to whom   3. supplied / sold / delivered   4. whose   5. in which

Sentence 2 is Mrs Donoghue's problem solved in advance: the duty follows the person who consumes, not the person who paid.

3. Advise the client — complete the answer

A small brewery asks you: "We sell to bars, not to the public. Are we responsible if a customer in a bar is made ill?" Complete the reply so that it opens wide, then narrows honestly. Read it aloud when you finish.

"The short answer is yes. Since 1932 your duty has not depended on who paid you. You owe reasonable care to any person can foreseeably be harmed by what you put into the market — and the drinker in the bar is exactly the person the product was always intended to reach. Because you supply in sealed containers, there is no realistic point the bar could inspect the contents, which strengthens the claim rather than weakening it. Where you have more protection is with a batch after leaving you — stored badly, decanted, or mixed. And a supplier records show a clean, documented process is in a very different position from one cannot say what happened on the day."

who · whom (or that … for) · at which · altered / tampered with / mishandled · whose · which / that

Notice the shape of the advice: one wide sentence that tells the client the truth, then three narrowing clauses that tell them where to put their effort. That order is the professional habit — the qualifications come after the answer, never instead of it.

Take these into the Speak tab: you will be defining the class of people your client is responsible to, under time pressure.

Going deeper

A note before we argue: the case is summarised here, dates and figures are approximate, and legal systems differ — this is material for discussion and for language, not legal advice on any real matter.

What the case actually tests. The comfortable reading is that justice arrived: a poor woman with no contract was given a remedy, and the law caught up with an industrial economy in which nobody meets the person who makes their food. That reading is true. It is also incomplete, because the majority did not simply extend an existing rule — they replaced the organising idea. Before 1932 the question was what did you agree to? After it, the question is who could you foresee? Those produce different worlds. The first is bounded by a document; the second is bounded only by imagination, and by whatever line the courts later decide to hold.

The second lesson is in the shape of the judgment itself. Lord Atkin gave two rules of very different width in the same speech, and left the profession to work out which one he meant. Courts have been narrowing and widening ever since: extending the principle far beyond products, then pulling it back sharply where the loss is purely financial, where the defendant merely failed to act, or where a public body is being sued for not preventing someone else's wrong. Modern practice asks not "is it foreseeable?" but something more cautious — is there sufficient proximity, and is it fair and reasonable to impose a duty here, and is this an incremental step from a decided case? That caution is Lord Buckmaster's dissent, wearing a new coat.

And a third, which is easy to miss. The case that governs product liability across the common-law world was decided on facts that were never proved and a snail that may never have existed. The House of Lords was asked a hypothetical and answered it. That is not a scandal — it is how a legal system upgrades itself: a small dispute is used as a vehicle for a rule, and everyone involved knows it. But it is worth noticing that the most famous claimant in the common law never got a trial, never got a judgment on her illness, and settled for a modest sum after the defendant died.
Talk it through:
  • Argue Lord Buckmaster's side properly, without irony: certainty in commerce is worth more than a remedy in a hard case, and a change of this size belongs to the legislature. What is the strongest version of that, and what does it cost?
  • "Who could you foresee?" is a test with no natural edge. In your sector, name the group at the outer edge of your organisation's foreseeable reach — the people you affect but have never counted as yours.
  • Modern courts prefer to move one small step at a time from decided cases rather than apply a grand principle. Is incremental caution wisdom, or a way of avoiding the question?
  • If the manufacturer's duty had been written by a parliament in 1932 rather than by five judges, what would be different about it now — and would you rather live under the statute or the principle?

Speak

All of it out loud, against the clock. These are the registers you actually switch between: explaining a rule, arguing a side you don't hold, and telling four different rooms the same thing.

Useful language: the duty is owed to any person who… · the class of people to whom… · in circumstances in which… · goods sold in a form that… · a supplier whose… · broadly, and then to narrow it… · the ratio of the case is… · with respect, that does not follow.
Time remaining: 4:00
Task A · Explain the case (4 minutes)

Present this case to an intelligent person who has never heard of it. Structure it: the café in Paisley → why she had no claim → the wall of privity and the 1842 rule → the question the Lords were actually asked → the neighbour principle and the narrow manufacturer rule → the dissent → what happened to the actual case.

Finish with one sentence saying what changed for everyone else. Use at least five key terms (privity of contract, duty of care, negligence, foreseeable, liability, precedent, ratio, dissenting judgment, damages, floodgates).

Task B · Argue the losing side (4 minutes)

You are Lord Buckmaster's counsel, and you must persuade a modern audience. Your case: the authorities were against this; the exceptions were narrow deliberately; a duty defined by foreseeability has no stopping point; and if the law of a whole economy is to change, Parliament should change it, having heard from the people it will bind.

Make it genuinely strong — no straw men, and concede what is genuinely conceded about Mrs Donoghue's position. Then do it again in ninety seconds — the compression is the exercise.

Task C · Four rooms, one rule (4 minutes)

Take one product or service and explain who is owed a duty of care — four ways, one minute each. Notice how much of the definition survives each translation.

  • To the client who makes it: the honest scope, including the people they have never thought of.
  • To a court: the same scope, in the register of a submission — defining clauses, no adjectives.
  • To an insurer or regulator: what the organisation does to keep itself inside the line.
  • To the person who was harmed: plain words, no jargon, nothing that sounds like a defence being built.

Prefer not to use anything of your own? Take one of these instead:

  • A bakery that supplies sealed sandwiches to offices, and an undeclared allergen.
  • A company hiring out e-scooters through an app, and a pedestrian who was hit.
  • A software vendor whose update stopped a hospital's appointment system for a day.
  • A landlord whose contractor serviced a boiler badly in a flat that has since been sublet.

To finish — the harder questions

  1. Is it legitimate for five judges to change the basis of liability for an entire economy, in a case whose facts were never proved? Argue one side properly.
  2. The wide principle and the narrow rule sat in the same judgment. When you write a policy or a clause, do you deliberately leave room for later interpretation — or is that a failure of drafting?
  3. Foreseeability keeps expanding: supply chains, data, environmental harm. Name one group your organisation affects that the law does not yet call your neighbours, and say whether it should.
  4. Before you go — from memory: define in one sentence, using a defining relative clause, who is owed a duty of care by a manufacturer. Then add a second clause that narrows it, and say exactly who your narrowing has just excluded.
