Air and Liquid Systems Corp., Petitioners v. Roberta G. Devries

Summary

The Court affirmed the Third Circuit, holding that under maritime tort law a product manufacturer must warn when its product requires incorporation of a part, the manufacturer knows the integrated product is likely dangerous, and the manufacturer has no reason to believe users will realize the danger. The decision vacates the district court’s summary‑judgment rulings and remands for reconsideration under this three‑part duty‑to‑warn rule.
