Manufacturers have a duty to make sure the products they sell to the public are safe. A defective product is any product that causes injury to a person due to faulty labeling, a design defect or defective manufacturing. When that defect makes the product unsafe, manufacturers may be held liable for injuries that result from it. Generally, the law that governs defective products is referred to as product liability. This area of law refers to the responsibility held by the manufacturer, designer, distributor, or retailer of any consumer product to ensure that it does not cause harm to the consumer. When a defective product is sold to the general public, many people could suffer the consequences of the defect. When this happens, all those who have been injured by the defective product may bring a class action lawsuit against the manufacturer.
