Key Takeaways
The U.S. Supreme Court heard arguments Monday on whether Monsanto (now owned by Bayer) can be sued for failing to warn users about cancer risks associated with its weed killer Roundup. The case centers on who decides about warning labels: the federal government or states/juries.
- Supreme Court hears arguments in Roundup cancer warning label case
- Case could impact tens of thousands of lawsuits against Monsanto/Bayer
- Plaintiff John Durnell won $1.25 million verdict for non-Hodgkin lymphoma claim
- EPA maintains glyphosate is not carcinogenic, while WHO classifies it as probable carcinogen
- Rally outside court protests Trump administration's support for Bayer
At the heart of the dispute is whether federal pesticide laws preempt state failure-to-warn claims. The main plaintiff, John Durnell, won a $1.25 million verdict in Missouri after alleging that 20 years of exposure to glyphosate (Roundup's active ingredient) caused his non-Hodgkin lymphoma.
The case has drawn significant attention from various groups filing legal briefs on both sides. Monsanto argues that state labeling requirements should not override federal EPA standards, which currently do not require cancer warnings for glyphosate. The EPA maintains the chemical is unlikely to be carcinogenic, though a World Health Organization agency classified it as a probable human carcinogen in 2015.
Outside the court, protesters affiliated with the "Make America Healthy Again" movement rallied against Bayer and the Trump administration's support for Monsanto. The rally featured speakers from environmental groups and Democratic lawmakers, with signs calling for corporate accountability over pesticide use.
