A:Strict liability is the legal principle that a person or company that sells a product in a “defective condition” that is unreasonably dangerous to the ordinary user may be liable for any resulting property damage or physical injuries. The defect may be in the product’s design or manufacturing, in the product’s container or packaging, or in the instructions or warning necessary for the product’s safe use. In a strict liability case, the injured person is not required to prove the manufacturer or seller was negligent.
