Strict product liability generally focuses on the product itself, not the negligent conduct of the defendant, and as a result, defendants often are precluded from relying on certain negligence concepts in defending strict liability actions. A plaintiff's comparative fault or contributory negligence, for example, generally may not be used to excuse a product's defects or reduce a defendant's fault. A recent decision from the U.S. District Court for the Middle District of Pennsylvania makes clear, however, that evidence of a plaintiff's negligent conduct may be admissible in a strict product liability case under limited circumstances. Dodson v. Beijing Capital Tire Co., 2017 U.S. Dist. LEXIS 158484, at *8-13 (M.D. Pa. Sep. 27, 2017). Because such evidence can be powerful in defending these types of actions, it is important to understand when and why it may be admissible.
In a strict product liability claim, compliance with government regulations and industry standards can be powerful evidence for the defense. Such evidence traditionally has been inadmissible under Pennsylvania law based on the Pennsylvania Supreme Court's decision in Lewis v. Coffing Hoist Div., Duff-Norton Co., Inc., 528 A.2d 590 (Pa. 1987). The Court's decision in Tincher v. Omega Flex, 104 A.3d 328 (Pa. 2014), however, raises questions about the continued viability of Lewis and provides defendants with a compelling argument that this type of evidence should be admissible. Nevertheless, Pennsylvania courts have been slow to reach that conclusion, and recent Superior Court decisions cast doubt on the admissibility of such evidence, which at best remains an open issue.
