Whether the Second Circuit should certify the plaintiffs' New York-law claims to the New York Court of Appeals.
Holding
No. Existing New York precedent, including closely analogous lower-state-court decisions, supplied sufficient guidance for the federal court to predict New York law.
Reasoning
Certification is discretionary. It is generally appropriate when state authority is genuinely divided, statutory text leaves a controlling question unresolved, or a complex common-law issue lacks meaningful New York authority. It is not a mechanism for transferring the federal court's ordinary obligation to decide diversity cases to the state court of last resort.
Although the New York Court of Appeals had not specifically addressed manufacturer liability for Black Talon ammunition, two New York trial-level cases had considered nearly identical claims against Olin. Those decisions, particularly the Appellate Division's affirmance in Forni v. Ferguson, rested on established New York tort principles and strongly informed the court's prediction of how New York's highest court would rule.
The court therefore concluded that the asserted theories were not so novel or uncharted as to warrant certification. Federal courts applying Erie may give substantial weight to intermediate state-court decisions while predicting state law, even though those decisions do not formally bind them.
