Overview
- The Supreme Court ruled on Thursday that the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) bars state failure-to-warn claims when the EPA has not required a cancer warning on a pesticide label.
- Justices vacated a $1.25 million Missouri jury verdict for John Durnell and issued the decision in a 7-2 split with Justice Brett Kavanaugh writing the majority and Justice Ketanji Brown Jackson dissenting.
- The ruling is a legal preemption decision about labeling and jurisdiction and does not settle the scientific question of whether glyphosate, Roundup’s active ingredient, causes cancer.
- The outcome threatens dismissal or narrowing of thousands of pending state suits against Monsanto/Bayer but leaves other legal paths open, including design-defect claims, federal refiling, settlements, or possible Congressional changes to FIFRA.
- Reactions split: industry and some commentators framed the ruling as restoring uniform federal regulation, while consumer advocates and former EPA officials said it limits state tools to protect people and early media coverage showed inconsistent details about the decision.
