Under the theory of strict product liability the plaintiff (injured party) must prove that a product that was defective caused their injuries, and that the defect made the product unreasonably dangerous. The three different types of product defects that may cause injury include: (1) a manufacturing flaw, (missing component, broken part) or it was not made as it was planned and should have been built; (2) the product design is incorrect; or (3) the product is inadequately labeled or lacks sufficient warning of its dangers.
