General Defintion
Products liability is the liability of a supplier of a product for physical harm to person or property caused by defective products. The three basic theories of recovery in products liability are negligence, warranty, and strict liability.
Negligence
Warranty – RS §402B
One engaged in the business of selling chattels who, by advertising, labels, or otherwise, makes to the public a misrepresentation of a material fact concerning the character or quality of a chattel sold by him is subject to liability for physical harm to a consumer of the chattel caused by justifiable reliance upon the misrepresentation, even though it is not made negligently.
Express warranty (Baxter v. Ford Motor Co.)
Implied warranty
Warranty: Scope of liability
A seller is liable even though the product is not made fraudulently or negligently, and the consumer has not bought the chattel from or entered into any contract relation with the seller
Warranty: Causation
Warranty: Damages
Strict Liability In Tort – RS §402A
One who sells any product in a defective condition unreasonably dangerous to the consumer or his property is subject to liability for physical harm thereby caused to the ultimate user or his property if (a) the seller is engaged in the business of selling such a product, and (b) it is expected to and does reach the user or consumer without substantial change in the condition in which it is sold. The rule applies although the seller has exercised all possible care.
Rationale for strict liability
Products defects – RS (Third) §2
A product is defective when, at the time of sale or distribution, it contains a manufacturing defect, is defective in design, or is defective because of inadequate instructions or warnings
Manufacturing defect
Design defect
Tests to determine whether a design is defective: Risk Utility Analysis
Tests to determine whether a design is defective: Consumer expectation test
P must prove that the product did not perform as safely as an ordinary consumer would have expected
test to determine whether a design is defective: Combined approach
Risk-utility test is combined with consumer expectations test
test to determine whether a design is defective: time of trial
Compares the risk and utility of the product at the time of trial
Design defect: Feasible alternative design
Design defect: State of the art
Design defect: Open and obvious danger
Open and obvious danger is considered as a defense to a design defect case
Design defect: Allergic reactions
Failure to warn issue – manufacturer only has a duty to warn of possible adverse reactions if it knew or should have known of the risks
Inadequate warnings: definition and elements
Testing adequacy of warning
A warning may be inadequate if it is incomplete, is inconsistent with how the product is used, or does not give the reason for the warning
Testing who must receiving warning
