Products Liability Law differs from ordinary injury law; it is the specific set of legal rules used to determine who is at fault in cases of defective or dangerous products. A product is said to be defective if it fails to meet the ordinary expectations of consumers. All manufacturers or sellers of a defect product may be found liable for the damages or injuries that it causes. Because of this, there are a number of parties that may be liable, including the manufacturer of the product, a manufacturer of component parts, the wholesaler, and the retail store. The specifics of Products Liability Law are determined on a state by state basis.
