--- title: "MacPherson v. Buick Motor Co." type: Landmark Case source: https://casebriefly.com/landmark-cases/macpherson-v-buick-motor-co --- # MacPherson v. Buick Motor Co. MacPherson is a landmark case that eliminated the privity of contract requirement for negligence actions against manufacturers. Judge Cardozo held that a manufacturer owes a duty of care to all foreseeable users of its products, not just those with whom it has a direct contractual relationship. This decision opened the door to modern products liability law. ## Citation 217 N.Y. 382, 111 N.E. 1050 (1916) ## Year 1916 ## Court New York Court of Appeals ## Facts Donald MacPherson purchased a Buick automobile from a retail dealer. While driving the car, a defective wheel collapsed, causing the car to overturn and injure MacPherson. The wheel had been manufactured by a third party and sold to Buick, which incorporated it into the car. Evidence showed that the defect could have been discovered by reasonable inspection, which Buick failed to perform. ## Procedural History The trial court entered judgment for the plaintiff. The Appellate Division affirmed. The New York Court of Appeals affirmed, with Judge Cardozo writing the opinion. ## Issue Whether a manufacturer owes a duty of care to the ultimate purchaser of its product when there is no privity of contract between the manufacturer and the injured party. ## Holding The court held that a manufacturer of a product that is reasonably certain to place life and limb in peril if negligently made owes a duty of care to the ultimate user, regardless of privity of contract. The manufacturer is liable in negligence if it fails to exercise reasonable care in manufacturing or inspecting the product and the defect causes injury to a foreseeable user. ## Reasoning Judge Cardozo reasoned that the old rule requiring privity of contract, established in Winterbottom v. Wright, was obsolete and did not reflect the realities of modern commerce. When a manufacturer puts a product into the stream of commerce knowing it will be used by persons other than the immediate purchaser, the manufacturer owes a duty to all who foreseeably might be endangered by the product's defects. The principle of Thomas v. Winchester, which recognized an exception for inherently dangerous products, should not be limited to specific categories but should apply broadly to any product that is dangerous if defectively made. Cardozo synthesized the prior cases to articulate a general rule of duty based on foreseeability. ## Impact MacPherson effectively ended the privity requirement in American products liability law and established the principle that manufacturers owe a duty to foreseeable users of their products. The case was adopted across the country and paved the way for the later development of strict products liability in Greenman. It is one of the most celebrated examples of common law evolution through judicial reasoning. ## Key Quotes - If the nature of a thing is such that it is reasonably certain to place life and limb in peril when negligently made, it is then a thing of danger. - The manufacturer of this thing of danger is under a duty to make it carefully. - We have put aside the notion that the duty to safeguard life and limb, when the consequences of negligence may be foreseen, grows out of contract and nothing else. ## Related Cases - greenman-v-yuba-power-products - escola-v-coca-cola-bottling - palsgraf-v-long-island-railroad - sindell-v-abbott-laboratories ## Exam Relevance MacPherson is tested in the context of the evolution of products liability doctrine, particularly the elimination of the privity requirement. Students should understand how Cardozo extended the dangerous instrumentality exception into a general principle and how this set the stage for strict products liability. ## Study Tips - Understand the significance of eliminating privity: before MacPherson, injured users could not sue manufacturers they did not purchase from directly. - Note Cardozo's method of reasoning from specific exceptions to a general rule — this is a masterclass in common law evolution. - Connect this case to Cardozo's later Palsgraf opinion, both of which address the scope of duty based on foreseeability. - Trace the line from MacPherson (negligence without privity) to Escola (policy arguments for strict liability) to Greenman (strict liability adopted). ## Doctrine Established Elimination of Privity Requirement in Products Liability --- Source: [MacPherson v.
