In a product liability case, the consumer must prove several key elements to successfully hold the manufacturer, distributor, or seller responsible for injuries caused by a defective product. These elements vary depending on the type of defect (e.g., design defect, manufacturing defect, or warning defect) and the legal theory under which the case is being pursued (e.g., strict liability, negligence, or breach of warranty). However, in general, the consumer must prove that the product was defective, that the defect caused their injury, and that the manufacturer or seller is legally responsible for the harm.
The core of any product liability case is proving that the product was defective in some way. The defect could fall into one of three categories:
Example: A toaster that is prone to overheating due to a faulty design would be considered defectively designed. If the same toaster was manufactured with faulty wiring, it would be a manufacturing defect.
The defect must make the product unreasonably dangerous to consumers. This means the product's risk of harm is beyond what a typical consumer would expect under normal use.
Example: A baby crib with a design flaw that causes the slats to be too wide and results in a choking hazard would be considered unreasonably dangerous to infants.
The consumer must prove that the defect in the product was the direct cause of their injury. This involves establishing a causal link between the defect and the harm. The consumer must demonstrate that the injury would not have occurred if the product had not been defective.
Example: If a consumer is injured when a ladder collapses due to a faulty weld, the consumer must prove that the defective weld directly caused the fall and resulting injuries.
In many product liability cases, the consumer must prove that they used the product as it was intended to be used. If the product was misused, the manufacturer may not be held liable.
Example: If a lawnmower designed for residential use is used on a construction site and causes injury, the manufacturer may argue that the product was not used as intended, potentially weakening the claim.
In most cases, the consumer must prove that the defendant (manufacturer, distributor, or seller) is legally responsible for the defective product. This may be easier to establish in cases where the defendant is the manufacturer or seller of the product, but third parties (e.g., suppliers or repair companies) could also be held accountable under certain circumstances.
Example: A pharmaceutical company could be held liable for selling a defective drug even if the drug was sold through a distributor or retailer.
The consumer must prove that they suffered actual damages as a result of the injury caused by the defective product. This includes medical expenses, lost wages, pain and suffering, and any other economic or non-economic losses incurred due to the defect.
Example: In a case where a consumer is injured by a defective power tool, they must demonstrate the extent of their medical bills, lost income from missed work, and any long-term physical or emotional pain caused by the injury.
If a design defect is at the heart of the case, the consumer must prove that the product design itself is inherently unsafe. This may require expert testimony to show that the design is flawed and poses an unreasonable risk of harm.
Example: A car seat with a design flaw that fails to protect children in a crash would require expert analysis of how the design fails to meet safety standards.
In a case involving a manufacturing defect, the consumer must demonstrate that the product deviated from the manufacturer’s intended design or was improperly made. This type of defect often involves specific evidence, such as inspections or quality control records.
Example: A bottle of soda that is improperly sealed, leading to an explosion when opened, would require proof that the manufacturing process caused the defect.
For a warning defect, the consumer must prove that the product lacked adequate instructions or warnings about its risks, and that the failure to warn led to the injury. This typically involves analyzing whether the manufacturer failed to communicate known dangers or potential hazards.
Example: If a cleaning product fails to warn consumers of the risks of inhaling fumes, leading to respiratory injury, the consumer must show that the lack of proper warnings directly contributed to the harm.
The defendant may argue that the consumer misused the product in a way that was not foreseeable or intended by the manufacturer.
If the consumer modified or altered the product after purchase, the manufacturer may argue that the defect was caused by the consumer’s actions rather than an inherent flaw in the product.
The manufacturer may argue that the consumer’s own actions contributed to the injury. This can reduce the amount of damages awarded if proven.
If a consumer buys a defective ladder that collapses and causes injury, they would need to prove:
In a product liability case, the consumer must prove that the product was defective, that the defect caused their injury, and that the manufacturer or seller is responsible for the defect. Whether the defect is related to the design, manufacturing, or warnings, establishing causation and damages is crucial for a successful claim. By proving these elements, the consumer can seek compensation for medical expenses, lost wages, and other losses resulting from the defective product.
