Facts

Plaintiff, a Mississippi citizen, alleged that defendant, a Rhode Island corporation, negligently manufactured, inspected, and tested an emery wheel for attachment to a bench grinder, making it dangerously defective. Plaintiff's evidence showed the wheel was sold to Hoover Company, attached to a grinder, then passed through several commercial transfers until it reached plaintiff's employer in Mississippi. While plaintiff was using the grinder in the ordinary and proper manner during his employment, the wheel disintegrated and exploded in his face, causing serious injuries. Defendant denied negligence, denied manufacturing the particular wheel, and asserted that it owed plaintiff no duty because there was no privity of contract.

Issue

When a federal court applies Mississippi law to a negligence claim by an injured remote user against a manufacturer, must it follow an older Mississippi case requiring privity, or may it conclude that the Mississippi Supreme Court would now adopt the modern rule imposing a duty of reasonable care to foreseeable users without privity?

Rule

In determining state law, a federal court is not required to attribute to a state an outdated doctrine that has been generally discredited when later expressions of the state's highest court indicate readiness to adopt the modern rule. A manufacturer who fails to exercise reasonable care in manufacturing a chattel that, unless carefully made, involves an unreasonable risk of substantial bodily harm may be liable to persons who lawfully use it for its intended purpose even without privity of contract.

Lena Ortiz, a Nevada citizen, sues Summit Forge Tools, a fictional Ohio manufacturer, in federal court in Chicago after a cutting disc allegedly shattered while she was using it at work in Reno. Nevada's highest court adopted a no-privity bar in 1930, but a 2022 Nevada Supreme Court opinion in a property-damage case stated at length that modern authority permits recovery against negligent manufacturers by persons lacking direct contractual relations and quoted that rule approvingly while deciding the case on another ground.

How should the federal court most likely treat Nevada law on the duty issue?

Explanation. A federal court applying state law need not attribute to the state an outdated doctrine that has been generally discredited when later expressions from the state's highest court indicate readiness to adopt the modern rule. The majority opinion emphasized that an old case need not be expressly overruled to lose persuasive force and that later state-court indications can justify predicting adoption of the modern manufacturer-duty rule.
