Owens (D) were manufacturers of products containing asbestos. Carl Anderson (P) filed suit in 1984, alleging that he contracted asbestosis and other lung ailments through exposure to asbestos and asbestos products while working as an electrician at the Long Beach Naval Shipyard from 1941 to 1976. P allegedly encountered asbestos while working in the vicinity of others who were removing and installing insulation products aboard ships. P sued in negligence, breach of warranty, and strict liability and, inter alia, prayed for punitive damages. P proceeded only on his cause of action for strict liability and did not seek punitive damages. P alleged design and manufacturing defects' which caused injury to users and consumers, including P while being used in a reasonably foreseeable manner. A fourth cause included allegations of failure to warn. P alleged that D marketed their products with specific prior knowledge, from scientific studies and medical data, that there was a high risk of injury and death from exposure to asbestos or asbestos-containing products; that D knew consumers and members of the general public had no knowledge of the potentially injurious nature of asbestos; and that Ds failed to warn users of the risk of danger. D raised the state-of-the-art defense, i.e., that even those at the vanguard of scientific knowledge at the time the products were sold could not have known that asbestos was dangerous to users in the concentrations associated with Ds' products. P moved to prevent Ds from presenting state-of-the-art evidence. P was proceeding, as to defective design, only on the 'consumer expectation' prong of the design defect test. The trial court granted the motion holding that state-of-the-art evidence is irrelevant to any theory of strict liability. Ds then moved to prevent P from proceeding on the failure-to-warn theory on grounds of waiver and fairness. P offered catalogs and other literature depicting workers without respirators or protective devices and offered to prove that, until the mid-1960s, Ds had given no warnings of the dangers associated with asbestos, that various warnings given after 1965 were inadequate, and, finally, that Ds removed the products from the market entirely in the early 1970s. Ds argued that what was scientifically knowable in the period 1943-1974, was their obvious and only defense to any cause of action for failure to warn, and that, in view of the court's decision to exclude state-of-the-art evidence, fairness dictated P be precluded from proceeding on that theory. The trial court granted Ds' motion. The jury returned a verdict for Ds, finding in a special verdict that Ds' products had no design defects. P moved for a new trial, asserting that the court erred in precluding proof of liability on a failure-to-warn theory. The court granted the motion. The Court of Appeal upheld the order granting a new trial. It added that 'in strict liability asbestos cases, including those prosecuted on a failure to warn theory, state of the art evidence is not admissible since it focuses on the reasonableness of the defendant's conduct, which is irrelevant in strict liability.' The dissenting justice urged that the majority had imposed 'absolute liability,' contrary to the tenets of the strict liability doctrine and that the manufacturers' right to a fair trial included the right to litigate all relevant issues, including the state of the art of scientific knowledge at the relevant time.
