Donoghue v. Stevenson: The Neighbour Principle and Negligence

2026-06-12

Exam Snapshot

Donoghue v. Stevenson [1932] AC 562 is the ultimate foundation of modern tort law. It established negligence as an independent tort, created the "neighbour principle" for determining duty of care, and formulated consumer protection by establishing manufacturer's liability without privity of contract.

Core Concept

To establish negligence in tort law, three essential elements must be proven:

1. Duty of Care: The defendant owed a legal duty to take care.
2. Breach of Duty: The defendant failed to meet the standard of care required.
3. Consequential Damage: The breach caused reasonably foreseeable harm/injury to the plaintiff.

The Neighbour Principle

Formulated by Lord Atkin, this principle answers who a legal "neighbour" is:

"You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour."

A legal neighbour is defined as:

"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."

Manufacturer's Liability

Prior to this case, the "privity of contract" fallacy meant only the actual buyer could sue the seller under contract law. This case established that a manufacturer of products owes a duty of care to the ultimate consumer, regardless of contract.

Nepal Law Anchors

Negligence and product liability are codified under Muluki Civil Code, 2074:

• Section 672: General duty of care—everyone must act in a way that does not cause harm or damage to others.
• Section 673: Compensation for damage caused by negligent, reckless, or intentional acts.
• Section 681: Manufacturer's liability—manufacturers are strictly liable for damages caused by defective or unsafe products.
• Evidence Act, 2031 (Section 6): Recognizes judicial notice of globally established common law doctrines like negligence when applying general principles of justice, equity, and good conscience.

Confusable Terms

MCQ Traps

• The Buyer Trap: MCQs often ask if Mrs. Donoghue purchased the ginger beer herself. No, her friend purchased it. Had Donoghue purchased it, she would have sued in contract; because her friend did, she had to sue in tort.
• The Defective Product Trap: Donoghue v. Stevenson did not just establish liability for "snails" or "beverages"; it laid down the universal test for duty of care applicable to all negligent acts.
• Strict Liability vs Negligence: While the case established manufacturer duty of care, modern product liability under Nepal's Muluki Civil Code (Sec 681) leans towards strict liability, whereas Section 673 requires proof of fault/negligence.

Example

Mrs. Donoghue drank ginger beer from an opaque glass bottle manufactured by Stevenson. Her friend bought it from a cafe. As she poured the remains, a decomposed snail floated out. She suffered severe gastroenteritis and nervous shock. Because the bottle was opaque, intermediate inspection was impossible, creating a direct duty between the manufacturer and the ultimate consumer.
