Case Law
There are cases that reshape a single dispute. And then there are cases that reshape the law itself. Donoghue v Stevenson [1932] AC 562 is the second kind.
A Scottish woman found a decomposed snail in a bottle of ginger beer. What followed was a House of Lords decision that gave birth to the modern concept of negligence — the same concept that underpins every professional negligence claim brought in Australia today. Nearly a century later, Lord Atkin’s reasoning still echoes through our courtrooms.
Case at a glance
| Full case name | Donoghue v Stevenson [1932] AC 562 |
| Court | House of Lords, United Kingdom |
| Year decided | 1932 |
| Key parties | May Donoghue (appellant) v David Stevenson (respondent) |
| Decision | A manufacturer owes a duty of care to the ultimate consumer of their product, regardless of any contractual relationship between them |
| Legal principle | Established the modern law of negligence and the neighbour principle |
| Relevance to Australia | Foundational common law authority adopted and applied in all Australian superior courts |
It was August 1928. May Donoghue and a friend were at the Wellmeadow Café in Paisley, Scotland. Her friend bought her a bottle of ginger beer — the kind sealed in an opaque dark bottle, so there was no way of seeing what was inside.
Donoghue drank some of it. When her friend poured the rest of the bottle into her glass, the remains of a decomposed snail floated out. She became seriously ill — gastroenteritis and what the courts recognised as nervous shock.
Here was the legal problem. The friend had purchased the drink. Donoghue had no contract with the café, and no contract with the manufacturer, David Stevenson. Under the law as it existed at the time, your right to sue in negligence was largely tied to whether you had a contractual relationship with the person who harmed you. Donoghue had none.
So the question put before the courts was a genuinely hard one: can a manufacturer owe a legal duty of care to someone who bought nothing from them directly? Someone they had never met, never dealt with, and had no agreement with at all?
The answer — eventually — was yes.
The case reached the House of Lords, where it was decided by a narrow majority of three to two. The leading judgment was delivered by Lord Atkin, and it changed everything.
The majority held that Stevenson did owe Donoghue a duty of care. The fact that there was no contract between them was irrelevant to the question of whether a duty existed in law. Negligence, the court said, could stand entirely on its own.
Lord Atkin articulated what became known as the neighbour principle: you must take reasonable care to avoid acts or omissions that you can reasonably foresee would injure people who are so closely and directly affected by your conduct that you ought to have them in mind. Those people are your “neighbours” in the legal sense — not necessarily people you know, but people whose welfare your actions can reasonably be expected to affect.
This was a break from the way negligence had been understood before. Previously, courts had largely required some kind of pre-existing relationship — usually a contract — before a duty could arise. Lord Atkin swept that away. The question was no longer who you had an agreement with. It was who you could reasonably foresee being harmed by what you did.
The two dissenting judges disagreed, arguing that the extension of liability beyond contractual relationships was too broad a step. They were outvoted. The majority prevailed, and the law has never gone back.
What Donoghue v Stevenson gave the common law was not just a rule about ginger beer or food manufacturers. It gave the law a framework for thinking about when one person owes another a duty to take care.
The case introduced two central ideas that courts have applied ever since.
Before a duty of care can arise, it must have been reasonably foreseeable that careless conduct could cause harm to the person who was ultimately injured. The defendant does not need to have known exactly who would be affected — only that someone in the plaintiff's position could be.
The relationship between the parties must be close enough, in a legal sense, for it to be fair and reasonable to impose a duty. This does not mean physical closeness. It means the kind of relationship where one party's conduct is likely to directly affect the other.
These principles have been refined over the decades. In England, the Caparo Industries plc v Dickman [1990] 2 AC 605 decision added a third limb — whether it is fair, just and reasonable to impose a duty — creating what became known as the Caparo three-stage test.
Australian courts took a different path. The High Court has consistently declined to adopt a fixed, universal formula, preferring instead to develop the law incrementally through careful examination of the particular relationship and circumstances in each case. That approach was made explicit in Sullivan v Moody [2001] HCA 59, where the High Court confirmed that duty of care in Australia is to be assessed by reference to the nature of the relationship, the reasonable expectations of the parties, and whether it is appropriate for the law to recognise a duty in the circumstances.
But through all of that development, the foundation has not moved. The starting point is still Lord Atkin’s question: could you reasonably foresee that your careless conduct would harm this person?
Every professional negligence claim in Australia — whether it involves a solicitor, a doctor, an accountant, a financial adviser, or an engineer — ultimately traces back to the duty of care concept that Donoghue v Stevenson established.
When a court considers whether a professional owed their client a duty of care, the Donoghue principles are the foundation it builds on. The professional relationship almost always satisfies them: a qualified professional who undertakes work for a client can clearly foresee that negligent advice or substandard work will cause harm. The relationship is obviously proximate. And it is plainly fair and reasonable to hold a professional to a standard of care toward the person who engaged them.
Australian courts have since developed the Donoghue framework into doctrine that speaks directly to the professional context. In Rogers v Whitaker [1992] HCA 58, the High Court held that a medical professional’s duty of care extends not just to the quality of the treatment they provide, but to ensuring the patient is properly informed of material risks. In Perre v Apand Pty Ltd [1999] HCA 36, the High Court examined in detail how the duty of care operates where a professional’s careless conduct causes pure economic loss — a question that arises frequently in claims against solicitors, accountants, and financial advisers.
The practical application is more straightforward than the theory. When a lawyer misses a limitation period and a client loses their case, the professional had a duty of care. When a doctor proceeds without informing a patient of a risk that eventuates, the professional had a duty of care. When a financial adviser recommends investments they had no basis for recommending, the professional had a duty of care.
The duty itself is rarely in dispute in a professional negligence claim. What matters is whether it was breached — and whether that breach caused your loss.

Understanding the legal foundation is one thing. Knowing whether it applies to your situation is another. If a professional’s failure has caused you real loss — financial, physical, or otherwise — the principles in Donoghue v Stevenson and the cases that followed it are the same principles our lawyers apply when assessing your claim.
