The U.S. Supreme Court ruled 7-2 in favor of Monsanto and parent company Bayer, overturning a Missouri verdict that awarded $1.25 million to a man who claimed long-term Roundup use caused his non-Hodgkin lymphoma. The case centered on whether federal pesticide labeling requirements under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) preempt state-level failure-to-warn claims. The Court concluded that because the U.S. Environmental Protection Agency has approved Roundup’s label without a cancer warning, state courts cannot impose different labeling requirements through litigation.

The decision is expected to have broad implications for thousands of pending Roundup lawsuits and represents a significant legal victory for Bayer, which has spent years defending claims that glyphosate, Roundup’s active ingredient, causes cancer. While Bayer maintains that scientific and regulatory reviews support the product’s safety, critics argue the ruling limits legal options for plaintiffs pursuing similar claims. The case marks one of the most consequential legal developments in the ongoing debate surrounding glyphosate and pesticide liability.
