#1617 1916 · New York Court of Appeals (Judge Benjamin Cardozo) · Automotive / product liability law
A court ruled a carmaker owed a duty to a driver it never sold a car to directly
the problem
A manufacturer's defective product injured someone who had bought it from a dealer, with no direct contract between them
background
In 1911 Donald MacPherson, a stonecutter, was thrown from his Buick Runabout and injured when one of its wooden wheels, made of defective wood, collapsed while the car was in motion. Buick had not manufactured the wheel itself, sourcing it from another supplier, and had sold the finished car not to MacPherson directly but to a retail dealer in Schenectady, who then sold it on to MacPherson.
Under the established legal doctrine of privity of contract, a manufacturer's duty of care traditionally extended only to the party it had directly contracted with, in this case the dealer, not to a subsequent buyer several steps removed from the original sale. Buick's defense rested squarely on this doctrine: because no direct contractual relationship existed between Buick and MacPherson, the company argued it owed him no legal duty regarding the car's condition, regardless of whether reasonable inspection would have caught the defect.
what everyone would do
Argue narrowly and technically that no direct contractual relationship existed between the manufacturer and the injured party, relying on the established privity doctrine to limit liability strictly to immediate purchasers, the defense Buick itself mounted and the conventional legal position manufacturers of the era generally relied on.
what they saw
Buick's defense was no contract, no duty. Cardozo ruled the contract was beside the point: a defect reasonably certain to cause harm makes the manufacturer answer to whoever gets hurt.
the move
Writing for the New York Court of Appeals, Judge Benjamin Cardozo rejected the privity defense, holding that when a manufacturer has reason to know a product will be used by people other than the immediate buyer, and that a defect is reasonably certain to place life and limb in peril if the product is negligently made, a duty of care extends to any foreseeable end user regardless of whether a direct contract exists. The ruling didn't impose strict liability, Cardozo explicitly limited it to cases where injury was probable rather than merely possible, and to products a manufacturer should reasonably expect to be dangerous if defectively made, but it fundamentally dismantled the contractual wall that had previously shielded manufacturers from responsibility to anyone beyond their immediate commercial counterparty. The decision, decided March 14, 1916, became one of the most cited and taught cases in American tort law, effectively founding the modern doctrine of manufacturer product liability that governs how nearly every consumer product defect claim in the US is analyzed today, and outlets including Columbia Magazine have retrospectively credited the case with reshaping how courts and manufacturers alike think about accountability across a multi-step distribution chain, from factory to dealer to end user.
why it works
The ruling's durability came from anchoring the duty of care in foreseeability and risk rather than in the formal structure of who transacted with whom, which meant the doctrine could scale cleanly to the increasingly complex, multi-step distribution chains modern manufacturing relies on, where a product routinely passes through several intermediaries before reaching an end user. By tying legal responsibility to the manufacturer's actual knowledge and control over the product's safety, rather than to a contractual technicality unrelated to that risk, the doctrine closed a loophole that had let manufacturers reasonably foresee harm while remaining legally insulated from it.
the payoff
Cardozo's 1916 ruling held manufacturers owe end users a duty of care regardless of contract, reshaping US product liability.
where it breaks
The doctrine specifically does not impose strict liability; Cardozo limited it to injuries that are probable rather than merely possible and to products a manufacturer should reasonably expect to be dangerous if made negligently, meaning genuinely unforeseeable misuse or defects outside a manufacturer's reasonable knowledge and control still fall outside the duty. The ruling also does not eliminate a manufacturer's ability to defend itself by showing reasonable care was actually exercised, inspection and quality practices, not mere distance from the end user, remain the operative defense.
what came after
Became one of the most cited and taught cases in American tort law, founding the modern doctrine of manufacturer product liability that governs how consumer product defect claims are analyzed in the US today, decades before formal product liability statutes existed.
