False Seed Batch Texts Trigger Cancellations
Terry sent bulk messages to Valley Harvest and neighboring farmers claiming Black Grain's seed batch failed germination tests. The statements were false. Valley Harvest canceled its season order within hours and told other farmers, causing Black Grain to lose an entire season's revenue. The rapid cancellations and explicit references to the falsehood show it operated as a substantial factor in the pecuniary loss.
Report Causes Direct Contract Losses
Star Sustainability distributed a report to Pinnacle Conservation and other factories stating Noon Environmental manipulated pollution samples. Multiple factories canceled monitoring contracts within weeks and cited data-integrity concerns. Noon Environmental incurred direct revenue loss from the terminated contracts plus expenses to regain clients. The losses flowed immediately from third-party reactions to the publication.
False Facts Permit Recovery
Marilyn sent Delta Museum a dossier alleging Central Museum had sold forgeries. Central Museum had no history of forgeries and the statements were false. Delta canceled planned acquisitions after receiving the dossier. Because the facts stated were untrue, the publisher remains subject to liability for the resulting lost sales.
Plaintiff Must Prove Interest and Injury

Common questions
Frequently Asked
6
What must a plaintiff prove to establish legal causation in a product disparagement claim?+
The plaintiff must show the publication was a substantial factor in bringing about the pecuniary loss and that no rule of law relieves the publisher of liability because of the manner in which the loss occurred. Direct temporal proximity and explicit references by third parties to the falsehood support a finding that the publication was a substantial factor.
What damages are recoverable in a product disparagement action?+
Recovery is limited to pecuniary loss that results directly and immediately from third-party conduct, including impairment of vendibility, plus expenses reasonably necessary to counteract the publication such as litigation costs. Proof may come from specific identified persons or from the aggregate conduct of unidentified persons.
Does truth provide a complete defense to product disparagement?+
Yes. The publisher is not liable if the facts stated or implied as justification for any opinion are true. The defense applies even when the statement concerns a matter of public concern.
Who bears the burden of proof on key elements in an injurious falsehood claim?+
The plaintiff must prove the existence and extent of its legally protected interest affected by the falsehood and the injurious character of the statement when those issues are properly raised. The plaintiff also carries the burden on causation and damages.
How does the First Amendment affect product disparagement claims involving media defendants?+
Courts have applied the actual malice standard from New York Times v. Sullivan to product disparagement claims brought against media defendants. The Supreme Court has accepted the application of that standard for purposes of deciding individual cases without definitively resolving whether it must always apply.
Does a general economic downturn automatically defeat causation in a product disparagement case?+
No. Concurrent market forces do not automatically sever the causal chain. The question remains whether the false publication was a substantial factor in producing the loss even when other economic conditions also influenced third-party decisions.
