Daley v. A.W. Chesterton (majority)Annotate this Case
In this appeal by allowance, the Supreme Court considered whether the "separate disease" rule (also referred to as the "two-disease" rule) allows an individual to bring separate lawsuits for more than one malignant disease which allegedly resulted from the same asbestos exposure. The matter arose from Appellee Herbert Daley's 1989 diagnosis of pulmonary asbestosis and squamous-cell carcinoma in his right lung. He filed suit against several defendants seeking compensatory damages for work-related injuries and settled. In 2005, Appellee filed suit against US Supply, Duro-Dyne and A.W. Chesterson alleging that a late diagnosis of mesothelioma was caused by the same exposure that resulted in his lung cancer. The companies argued that Pennsylvania had not adopted the two-disease rule, and that his mesothelioma diagnosis was barred by a two-year statute of limitations. Upon review, the Court concluded that the rule did apply, and, accordingly, the Court affirmed an order of the Superior Court, which reversed the trial court's grant of summary judgment in favor of U.S. Supply Co. and Duro-Dyne Corp.
