Background
Douglas Larry Belger suffered extensive burns and later died after his clothing allegedly ignited near an Enerco “Mr. Heater” Model MH15T propane tank-top heater in his nephew’s workshop. Jesse Near, representing Belger’s estate, sued Enerco under South Carolina law, alleging that the heater was defectively designed because it lacked an adequate guard or another feasible design that would prevent clothing from igniting when a person came too close. Near did not bring a separate failure-to-warn claim.
Enerco argued that warnings supplied on the packaging, a hangtag, the owner’s manual, and the heater itself rendered the product nondefective as a matter of South Carolina law. The district court excluded Near’s human-factors expert, Dr. Nancy Grugle, because her warning opinions were not based on a reliable methodology. It then treated the warnings as adequate, held that adequate warnings precluded the design-defect claim under Fourth Circuit precedent, and granted Enerco summary judgment. Near appealed the expert exclusion, the refusal to certify the state-law question, and the summary-judgment ruling.
The Court’s Holding
The Fourth Circuit affirmed the exclusion of Grugle’s testimony. The court concluded that the district court acted within its discretion in finding her warning opinions unreliable under Federal Rule of Evidence 702. Among other shortcomings, she did not inspect or operate the heater, test how users perceived its hazards, identify a specific alternative warning, or offer an adequately supported causation opinion.
The court did not finally decide whether the heater’s warnings defeated Near’s design-defect claim. Instead, it certified to the Supreme Court of South Carolina the question whether adequate product warnings preclude a design-defect claim as a matter of South Carolina law. The court explained that its earlier decision in Hickerson v. Yamaha Motor Corp. had predicted that adequate warnings do preclude such claims, but the state’s highest court had never answered the precise question, and its intervening design-defect framework in Branham v. Ford Motor Co. created sufficient uncertainty to warrant certification.
Accordingly, the Fourth Circuit affirmed the expert-evidence ruling but deferred consideration of the district court’s grant of summary judgment pending the South Carolina Supreme Court’s response to the certified question.
Key Takeaways
- The Fourth Circuit left unresolved whether an adequate warning categorically defeats a South Carolina design-defect claim and asked the state’s highest court for an authoritative answer.
- The court affirmed exclusion of the estate’s human-factors expert because her warning opinions lacked a sufficiently reliable methodology under Rule 702.
- Enerco’s summary-judgment victory remains under appellate consideration and will depend on the South Carolina Supreme Court’s treatment of the certified question.
Why It Matters
The certified question could determine whether South Carolina manufacturers may rely on adequate warnings as a complete defense to claims that a product should have been designed more safely. The answer may clarify the relationship between South Carolina’s statutory adoption of Restatement (Second) of Torts § 402A, including comment j, and the risk-utility test adopted for design-defect cases in Branham.
The decision also underscores that an expert challenging product warnings must connect the opinion to a reliable, case-specific methodology. General human-factors expertise, without inspection, testing, a concrete alternative warning, or supported causation analysis, may not satisfy Rule 702.
