Summary
The California Court of Appeal affirmed a judgment against Monsanto arising from Mike Dennis’s failure-to-warn claims concerning Roundup and non-Hodgkin’s lymphoma. The court held that FIFRA did not preempt the California claims because the state-law duties paralleled federal misbranding requirements. The court also upheld the trial court’s reduction of the jury’s punitive damages award from $325 million to $21 million against Monsanto’s due-process challenge.

Questions Presented
- Whether the Federal Insecticide, Fungicide, and Rodenticide Act expressly or impliedly preempts California failure-to-warn claims concerning Roundup's alleged cancer risk.
- Whether the reduced punitive damages award violates due process by punishing Monsanto multiple times for the same conduct.
Holdings
- FIFRA does not expressly or impliedly preempt Dennis's California negligent and strict-liability failure-to-warn claims because the state-law duties parallel FIFRA's requirements that pesticide labels contain warnings and instructions necessary to protect health.
- The $21 million punitive damages award did not violate due process by punishing Monsanto multiple times for the same conduct.
Key quotations
“Here, as in Pilliod, the verdict does not impose a requirement that Monsanto include a cancer warning; rather, it enforces the parallel requirement that Monsanto include all warnings necessary to protect health and, in doing so, could serve to incentivize Monsanto to provide accurate reporting to the EPA and/or file an amended application seeking a cancer warning for Roundup.” (p. 18)
“Here, by contrast, the punitive damage award was based on Monsanto’s “highly reprehensible conduct” directly related to Dennis’s physical harm and suffering.” (p. 23)
Factual background
Mike Dennis applied Monsanto's Roundup herbicide around his home monthly throughout the year from 2000 through 2020. He was diagnosed with mycosis fungoides, a form of non-Hodgkin's lymphoma, in June 2020. Dennis alleged that Roundup exposure caused his cancer and that Monsanto knew or should have known of the risk but failed to provide adequate warnings. The jury found that Roundup presented a substantial danger when used as commonly practiced, that Monsanto knew or should have known of the danger, and that the inadequate warnings substantially caused Dennis's illness.
Procedural history
Dennis sued Monsanto for design defect, negligent and strict-liability failure to warn, and negligence based on his alleged exposure to Roundup and subsequent diagnosis of mycosis fungoides. A jury found Monsanto liable and awarded $7 million in compensatory damages and $325 million in punitive damages. The trial court reduced punitive damages to $21 million and entered an amended judgment. The Court of Appeal affirmed and awarded Dennis costs on appeal.
