Grant v Australian Knitting Mills [1936] AC 85
Facts
The claimant bought woollen underwear which had been manufactured by Australian Knitting Mills. Residual chemicals from the manufacturing process remained in the garments and caused serious dermatitis when he wore them. The harmful condition was not one an ordinary consumer would discover before use. He sued the manufacturer in negligence, notwithstanding the absence of a direct contract between them. The manufacturer pointed to the possibility that someone could have interfered with the garments after they left the factory. The Privy Council considered the manufacturer's duty and whether that theoretical possibility displaced the evidence connecting the defect with production.
Legal Issue
Did the manufacturer owe the ultimate wearer a duty concerning a hidden chemical defect, and did possible intermediate interference defeat the negligence claim?
Held
The Privy Council allowed the consumer's negligence claim against the manufacturer. The harmful manufacturing residue reached the wearer in circumstances where no reasonable intermediate examination was expected to reveal it. The principle in Donoghue v Stevenson was not confined to food or drink, nor did it require every product to be enclosed in an identical sealed container. A theoretical possibility of later interference did not displace the evidential conclusion that the manufacturing defect caused the dermatitis. The court therefore recognised responsibility despite the absence of a direct contract. This was a negligence decision based on a latent harmful defect, rather than an application of the later statutory product-liability regime.
⭐ Legal Principle
A manufacturer can owe the ultimate consumer a negligence duty concerning a latent harmful defect where no reasonable intermediate examination is expected. Grant applied Donoghue v Stevenson beyond food and drink; a merely speculative possibility of third-party interference did not defeat the proven causal case.
Significance
Grant is a Privy Council appeal from Australia routinely studied with English product-negligence authorities. It demonstrates that the manufacturer-consumer duty is not confined to sealed drink bottles. The defect in the underwear could remain undetected in ordinary handling and cause injury when used as intended. Modern statutory product liability supplies an additional route, but Grant's negligence analysis still requires breach and causation rather than treating every unsatisfactory garment as actionable.
Common exam questions about this case
Why was the duty not confined to food or drink?
The relevant principle concerned foreseeable injury from a latent manufacturing defect reaching the ultimate user without reasonable intermediate examination. Harmful chemicals in clothing raised the same protective concern as a contaminated consumable. The product category was therefore less important than the defect and the expected route to use.
Did a possibility of interference defeat the claim?
No. A merely theoretical opportunity for someone else to affect the goods did not outweigh the evidence connecting the condition to manufacture. Causation is decided on the evidence, not defeated by inventing unsupported alternatives. A substantiated intervening cause would require a different assessment.
How does Grant differ from a statutory defect claim?
Grant concerns negligence and therefore the manufacturer's failure to take reasonable care. The Consumer Protection Act provides a separate statutory framework based on entitled safety expectations and its own requirements and defences. A student should identify the route pleaded rather than merge the tests because both concern a harmful product.
