Susan Elaine Bostic, Individually and as Personal Representative of the Heirs and Estate of Timothy Shawn Bostic, Helen Donnahoe And Kyle Anthony Bostic v. Georgia-Pacific Corporation
Timothy Bostic died of mesothelioma. His relatives (Plaintiffs) sued Georgia-Pacific (and others) alleging exposure to asbestos from Georgia-Pacific's drywall joint compound caused his disease. The jury found Georgia-Pacific liable, but the court of appeals rendered a take-nothing judgment, finding insufficient evidence of causation. The Supreme Court of Texas affirmed the court of appeals' judgment. The Court held that the "substantial factor causation" standard applies to mesothelioma cases, rejecting the "any exposure" theory. It clarified that "but for causation" is not a separate strict requirement in multiple-exposure cases. It stated that proof of causation requires scientifically reliable evidence that the plaintiff's exposure to the defendant's product more than doubled the risk of contracting the disease. The Court found the evidence of causation legally insufficient as the plaintiffs did not establish an approximate dose or show that Georgia-Pacific's product more than doubled Bostic's risk.
