Narrative Opinion Summary
The case involves a product liability lawsuit filed by the plaintiff, Knepfle, following a motorcycle accident that resulted in severe head injuries. Knepfle alleged that her helmet, a Z1R Nomad, was defectively designed, causing it to become detached during the accident. The Eleventh Circuit Court of Appeals reviewed the district court's summary judgment in favor of the defendants, which included helmet manufacturers and distributors. Central to Knepfle's claim was the testimony of her expert, Dr. John D. Lloyd, which was excluded by the district court for being based on unreliable methodologies under Daubert standards. The district court also denied HJC's motion for summary judgment on personal jurisdiction grounds, finding that the company purposefully availed itself of the Florida market through its subsidiary. On appeal, the court found jurisdictional errors and reversed the district court's ruling, stating that Knepfle failed to establish an agency relationship or control necessary to attribute HJCA's marketing efforts to HJC. The appellate court affirmed the exclusion of Dr. Lloyd’s testimony and the summary judgment for the defendants, concluding that Knepfle did not present sufficient evidence of a design defect or meet the legal standards for establishing personal jurisdiction over HJC.
