To prevail on a strict product liability claim under Pennsylvania law, a plaintiff must prove the product at issue is defective, the defect existed when the product left defendant's hands, and the defect caused the harm. A product may be defective based on a manufacturing or design defect, or based on a failure to warn. Regardless of the theory, a plaintiff must satisfy one of two standards (or both) to show a product is defective: (i) a consumer expectations standard; and/or (ii) a risk-utility standard. In the wake of Tincher v. Omega Flex, Inc., 104 A.3d 328 (Pa. 2014), Pennsylvania courts continue to define the contours of these standards, and a recent decision from the Western District of Pennsylvania, Igwe v. Skaggs, 2017 U.S. Dist. LEXIS 99622 (W.D. Pa. Jun. 28, 2017), adds clarity to the consumer expectations standard in particular.
In Dolby v. Ziegler Tire & Supply Co., 2017 Pa. Super. Unpub. LEXIS 791 (Pa. Super. Feb. 28, 2017), a case that proceeded to trial solely on a strict-product-liability, failure-to-warn claim, the Superior Court recently affirmed an Allegheny County Court of Common Pleas decision granting defendants' motion for compulsory nonsuit following plaintiff's case in chief. This unpublished decision provides useful guidance regarding the burden of proof in a failure-to-warn case and whether a plaintiff is entitled to a presumption that had an adequate warning been given, it would have been followed.
