Monsanto Company v. Mike Dennis

In Monsanto Co. v. Durnell, 2026 WL 1825691 (U.S. June 25, 2026), this Court held that the Federal Insecticide, Fungicide, and Rodenticide Act “expressly preempts” “state-law failure-to-warn claim[s]” against Monsanto for failing to include “a cancer warning on Roundup’s label” when the Environmental Protection Agency has declined to require one. Id. at *13. In this case, the California Court of Appeal affirmed judgment on a state-law failure-to-warn claim brought against Monsanto for failing to warn consumers that its Roundup products allegedly cause cancer. The question presented is: Whether, in light of Durnell, this Court should vacate the decision of the California Court of Appeal and remand this case for further proceedings not inconsistent with Durnell.
