Donaghue v Stevenson 1932 and our duty of care


Paisley may be known for its patterns and its shawls, but this town to the west of Glasgow has a much greater claim to fame, at least according to those interested in the law.  For it was there, 90 years ago, that one of the most important legal decisions in history, and one that still has implications for medical practice today, had its origins.

Mrs Donoghue’s ginger beer

On the hot summer evening of 26 August 1928, Mrs May Donoghue, a shop assistant from the East End of Glasgow took a tram ride to Paisley.  There, she met a friend at the Wellmeadow Café and they decided to quench their thirst. Her friend bought the refreshments and Mrs Donoghue was served a glass containing ice cream over which the waiter poured some of a bottle of ginger beer making an iced drink or float.  After Mrs Donoghue drank some, her friend added more ginger beer from the dark glass bottle that had been left on the table.  As she poured, Mrs Donoghue noticed something fall into the glass, which she recognised as a decomposing snail.  Understandably, she immediately felt sick and became “shocked and ill.”  She was clearly affected by the event for she sought medical treatment three days later from her own doctor and again three weeks later in mid-September at Glasgow Royal Infirmary.

The legal case

Because it was her friend who had purchased the ginger beer, Mrs Donoghue had no contractual relationship with the café owner.  She would later learn that the only one she might sue would be the manufacturer of the drink, David Stevenson, whose name was clearly written on the dark glass bottle in large white lettering.  Moreover, she would have to prove negligence on his part, if she was to recover any damages and that claim of negligence would require there to be a duty of care between her and Stevenson.  However, at the time, the law supported the existence of a duty of care to people harmed by the negligent acts of others only in very limited circumstances.  These would include instances where a contract existed between the parties, if the manufacturer was acting fraudulently or if the product was inherently dangerous.  In Mrs Donoghue’s case none of these applied, but she was determined to seek such damages and engaged the Glasgow solicitor Walter Leechman.  Interestingly, Leechman’s firm had represented the unsuccessful pursuers in two recent similar “mouse in ginger beer” cases.  It seems more than a coincidence that of all the lawyers Mrs Donoghue might have consulted, the one she chose had both the experience and the resolve to pursue such a case.  Quite how she found him, or was directed to him, remains a mystery.  Leechman issued a writ against Stevenson claiming damages of £500 plus costs and noting that, “snails and the slimy trails of snails were frequently found” in the factory where his ginger beer was manufactured and bottled.

Stevenson’s counsel moved the Court of Session to dismiss the claim and were eventually successful.  Thus, Leechman now began the process of appealing the decision to the House of Lords.  However, Mrs Donoghue had no money.  Not only had she to declare herself in writing as a pauper so she could be absolved of the need to post security to cover any costs if her appeal was unsuccessful, but her counsel had to proceed in representing her without any guarantee of payment.

On 10 December 1931, five Law Lords met to hear the first of two days’ arguments in Mrs Donoghue’s case.  Some five months later they delivered their judgement and by a majority of three to two they agreed she did have a case.  Mrs Donoghue, they ruled, was owed a duty of care by the manufacturer and bottler of the ginger beer and she could bring an action against him.  This duty of care was founded on the “neighbour principle” eloquently expounded by one of the law lords, Lord Atkin.  He summarised this principle in the ruling as follows:

“The rule that you are to love your neighbour becomes in law, you must not injure your neighbour; and the lawyer’s question, Who is my neighbour? receives a restricted reply. You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour. Who, then, in law, is my neighbour? The answer seems to be—persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions which are called in question.”

The “lawyer’s question” referred to was the one asked of Jesus in Luke’s Gospel, and which prompted Christ to tell the parable of the Good Samaritan.  Indeed, Lord Atkin’s ruling was firmly based on his reading of Judeo-Christian scripture.

Our duty of care today

The importance of this ruling lay in its implications for our understanding of negligence.  In law, for there to be medical negligence three criteria must be met.  First, a doctor must owe a duty of care to the patient in question. Second, there must be a breach of that duty of care.  And third, the breach must result in harm to the patient.  Thus, the concept of “duty of care” is central to our understanding of negligence, and it may be defined as an obligation we hold to take care to prevent harm being suffered by others.   In defining to whom we owe this duty of care as our “neighbour”, Lord Atkin created a new basis for the law of negligence, and of course his wide definition of neighbour would certainly include any doctor’s patient.


Not long after the House of Lords had ruled that Mrs Donaghue would be entitled to recover damages if she could prove what she alleged regarding the snail, David Stevenson died.  His executors agreed an out of court settlement of £200 (almost £10,000 today) and as such the case never went to trial.  May Donoghue died in a Mental Hospital in 1958, likely unaware of the global impact that summer evening trip to Paisley had had some 30 years earlier.

Today, in Paisley you will find a small park, a bench and a memorial stone at the corner of Well St and Lady Lane where the café once stood.  Most locals know little of its significance, but occasionally you will see a stranger standing reading the inscription on the stone.  Often they will be lawyers, sometimes doctors, who have made the pilgrimage from England, from North America or from even further afield, just so they can stand on the spot where our duty of care and the concept of negligence began.

Post script

In everything that has been written about this case, including all of the original legal documents, the bottle in question is said to have contained “ginger beer”.  What is perhaps not widely known is that the term “ginger” is a colloquialism in Glasgow for any fizzy drink.  It is possible that in reality the bottle did not contain true “ginger beer” but some other form of flavoured, aerated water such as orangeade referred to by Mrs Donoghue and her friend as “ginger”. Whether the bottle contained a snail at all is also a subject of controversy.  Some have argued that Mrs Donoghue’s claim was just a hoax to extort compensation.  Whatever the truth of the contents of that bottle, it remains the reason for our understanding of negligence around the world.

One thought on “A Snail in the Ginger Beer

  1. Loved it – thank you . Have to go to Paisely now – I might have said a duty of care was owed by the very action of making a drink which was going t be consumed by others …doubly so if that other paid for it. Even though this case was before the NHS, a doctor having a duty of care towards a patient, in the NHS, seems more obvious ( less so in countries where it would appear legal to ignore that duty of care if the patient does not have Medical Insurance).
    The word “Neighbour” might make me a bit jittery ….walking down the street/in a crowded bus …do I owe a duty of care towards those who happen to be near me… as the action of moving itself at a different pace, as a reaction to a sudden thought …could alone make me breach that duty of care ….I will become a bag of nerves ….maybe one should become a hermit….
