Narrative Opinion Summary
In the case of Diehl v. Blaw-Knox, the plaintiffs, involving a products liability claim, argued that a road-widening machine manufactured by Blaw-Knox was defective, leading to severe injuries. The alleged defects included the absence of rear wheel enclosures and inadequate warning systems. The plaintiffs sought to introduce evidence of subsequent remedial measures taken by a non-party, IA Construction, to support their claims. The District Court excluded this evidence under Federal Rule of Evidence 407, which led to a jury verdict in favor of Blaw-Knox. On appeal, the court found that Rule 407 does not apply to remedial measures by non-parties and that excluding such evidence was a significant error. Additionally, the appellate court criticized the District Court's use of Federal Rule of Evidence 403, finding no undue prejudice or jury confusion in admitting evidence of the redesign. The judgment was reversed, and the case was remanded for a new trial. The ruling emphasized the importance of considering post-sale design changes under Pennsylvania law to infer defects in the original design, and clarified the misapplication of evidentiary rules by the lower court.
