In Hammond v. North American Asbestos Corp., 97 Ill. 2d 195, 206, 454 N.E.2d 210, 73 Ill. Dec. 350 (1983), the supreme court held, "In a products liability action, all persons in the distributive chain are liable for injuries resulting from a defective product, including suppliers, distributors, wholesalers, and retailers." The court held that the imposition of liability upon these parties is justified on the ground that their position in the marketing process enables them to exert pressure on the manufacturer to enhance the safety of the product. Hammond, 97 Ill. 2d at 206.
