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, and there are a few different types of products liability. All manufacturers or sellers of a defective 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. Experienced products liability attorneys know the laws in their states, and even accross states, allowing them to protect the rights of those who have been harmed by defective products.
