What are the facts?
Plaintiff Greenman was injured by a power tool called the Shopsmith, which was manufactured by the defendant, Yuba Power Products, Inc. Greenman's wife purchased the Shopsmith for him as a gift, and shortly after using it, a piece of wood flew from the machine and struck him on the head, causing injuries. The tool had been marketed as a versatile product capable of carrying out various woodworking functions. Greenman sued the manufacturer, arguing that the Shopsmith was defectively designed and manufactured, leading to his injury. He claimed that despite careful use and following instructions, the product failed, and thus, Yuba was responsible for the damages suffered.

What did the court hold?
Yes, the Supreme Court of California held that a manufacturer can be held strictly liable in tort for personal injuries caused by defects in the product it sells, regardless of the manufacturer's level of care.
What is the reasoning?
The court reasoned that the costs of injuries resulting from defective products should be borne by the manufacturers that put such products into the market, rather than by the injured persons who are often powerless to protect themselves. The court highlighted that warranties should provide a foundation for consumer protection, and the injured party should not be burdened with proving negligence when it is the manufacturer’s responsibility to ensure the safety of its products. Thus, the introduction of strict liability promotes greater accountability and encourages higher safety standards by manufacturers.
