The Matter of New York City Asbestos Litigation , Doris Kay Dummitt v. A.W. Chesterton , The Matter of Eighth Judicial District Asbestos Litigation , Joann H. Suttner v. A.W. Chesterton Company
This New York Court of Appeals opinion addresses the scope of a manufacturer's duty to warn regarding dangers arising from the use of its product in combination with a third-party product. The Court held that such a duty exists when the third-party product is necessary for the manufacturer's product to function as intended, whether due to design, mechanics, or economic necessity, and the danger is known and foreseeable. Applying this rule, the Court affirmed judgments against Crane Co. in two separate asbestos litigations, finding that Crane had a duty to warn users of its valves about asbestos exposure from third-party sealing components. The decision clarified the balance of risks and costs in products liability law.
