“Every Breath” of Asbestos Is Not a Substantial Factor in Pennsylvania

The Pennsylvania Supreme Court unanimously found that plaintiffs cannot rely on the theory that “every breath” is a substantial contributing factor in causing an asbestos-related disease in an asbestos case involving friction exposures, i.e., brakes and clutches. The May 23, 2012, ruling in Diana K. Betz v. Pneumo Abex LLC (“Simikian”) overturns the en banc decision of the state Superior Court, which the Pennsylvania Supreme Court found to be based on an “unduly cramped perspective.” This decision changes the face of asbestos litigation in Pennsylvania and may have farther-reaching impact. Plaintiffs can no longer lump together exposures and say all exposures contributed to disease. This brings asbestos litigation in line with the mainstream causation requirements for other substances—plaintiffs must be able to prove that each product was a substantial factor in their disease. (Note: Duane Morris represented defendant Ford in this case.)
