Monsanto Co. v. Durnell (24-1068)
- Term
- OT 2025
- Argued
- 2026-04-27
Question Presented
Whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preempts a label-based failure-to-warn claim where EPA has not required the warning. FIFRA preempts state 'requirements for labeling or packaging in addition to or different from those required under' the Act. EPA has repeatedly found that Roundup's active ingredient glyphosate does not cause cancer and has approved Roundup's label without a cancer warning. Over 100,000 plaintiffs seek to hold Monsanto liable for not warning that glyphosate causes cancer.
Model prediction
Durnell 7-2 (72% confidence).
