Walsh v. BASF Corporation et al. (majority)Annotate this Case
Appellants, the manufacturers of various pesticides, appealed a Superior Court decision reversing the trial court’s grant of summary judgment in their favor following the trial court’s determination that the testimony of the experts proffered by Appellee, the Executor of the Estate of Thomas J. Walsh, failed to satisfy the test set forth in Frye v. United States, 293 F. 1013 (D.C. Cir. 1923). For nearly forty years, Walsh served as a groundskeeper and golf course superintendent at several Pittsburgh area golf courses. His work involved the regular application of various pesticides (primarily insecticides and fungicides) on the golf courses. Over this time, Walsh kept a detailed record of his activities regarding the pesticides he used, including a detailed log of the specific products and the dates of their applications. In 2008, Walsh was suffering from fever, chills, and a cough when he arrived at an emergency room. A bone marrow biopsy resulted in a diagnosis of Acute Myelogenous Leukemia (“AML”). Cytogenetic testing revealed significant chromosomal aberrations. On February 2, 2009, Walsh died. His treating oncologist, James Rossetti, D.O., later opined that Walsh’s extensive exposure to pesticides raised a high degree of suspicion that said exposure played a significant role in the development of his AML. After review, the Pennsylvania Supreme Court affirmed the Superior Court’s ruling, but gave instructions that on remand to the trial court, the Appellants should be given the opportunity to renew their Frye motions.
