US Supreme Court scales back Roundup cancer lawsuits

The U.S. Supreme Court has ruled that Bayer did not fail to warn its users about the cancer-causing active ingredient in Roundup weedkiller. This is a significant legal victory for the German 'company.

In a 7-2 ruling, the justices overturned a Missouri jury verdict awarding $1.25m to John Durnell who claimed he had been diagnosed with non-Hodgkin lymphoma following years of exposure. The Supreme Court agreed that Bayer's argument that the U.S. pesticide law prohibits state-law claims of failure to warn from being heard in court was correct.

Bayer was backed by the administration of President Donald Trump in this case.

Bayer purchased Roundup in 2018 as part of the $63 billion acquisition of Monsanto, an agrochemicals company. Bayer acquired Roundup as part of its $63 billion purchase of agrochemical company Monsanto in 2018.

Bayer was already forced to remove glyphosate in its consumer version Roundup due to the?torrent litigation. Bayer claimed before the Supreme Court's ruling that a favorable decision could end the Roundup litigation.

In April, the?Supreme Court heard argument in this case.

The U.S. Supreme Court's decision is good news for scientists, farmers and industries who depend on clear regulations to innovate. After nearly a decade of legal fights, it should be able to significantly reduce the Roundup litigation. The ruling will result in the dismissal and future barring of failure-to warn claims, said Tino Andresen, a spokesperson for the company.

The company stressed throughout the lawsuit that the U.S. Environmental Protection Agency found repeatedly?that cancer is not caused by glyphosate and approved their product labels without warning.

Bayer, facing billions in potential liabilities, announced in February that it would propose a $7.25 billion agreement to settle tens of thousands of existing and future lawsuits. According to the company, the settlement will not affect claims arising from appeals pending or outside of the deal. It said that the settlement would not affect claims arising from pending appeals or outside of the deal.

"A DISASTER for Public Health"

Environmental activists and other critics criticized Thursday's court ruling.

"The Supreme Court has once again sided with the big business against the people and environment. "Today's ruling is disastrous for public health," Tarah Heinzen said, the legal director of advocacy group Food and Water Watch.

Kelly Ryerson, coexecutive director at advocacy group American Regeneration, and Make America Healthy Again activist, who uses the social media handle "The Glyphosate Girl" to post on Facebook, said: "The harm caused by this decision will perpetuate cancer, infertility, and chronic diseases for generations to follow."

The dispute is centered on the Federal Insecticide, Fungicide and Rodenticide Act (or FIFRA) of the United States, which governs the labeling and sale of pesticides and prohibits states from imposing different or additional requirements.

To protect the environment and health, this measure bans pesticides with "misbranded labels" that do not contain adequate warnings.

Bayer argues that Durnell’s claims are preempted under this law. The EPA approved labels repeatedly without a cancer warning demonstrating 'that these products aren't misbranded,' the?company stated. Labels cannot be changed substantially without approval from the agency.

Durnell's attorneys said that despite Roundup's registration by the EPA, the label could still be challenged for being misbranded. Durnell's lawyers also claimed that Durnell's claims were not preempted by Missouri state law, which requires products to adequately alert consumers of potential dangers.

Durnell filed a lawsuit against Monsanto at the Missouri state court level in 2019. He claimed that?it did not warn users about the dangers of Roundup and Glyphosate.

He was diagnosed with non-Hodgkin's lymphoma (a cancer that begins in white blood cells), a rare, aggressive form. The disease, which began in 1996, was attributed to his exposure to Roundup. According to court documents, he was the "spray man" for about 20 years, spraying Roundup in local parks without wearing protective gear.

In 2023, a jury found in Durnell's favor. A state court of appeals upheld this verdict in 2025.

Activists with the "Make America Healthy Again", a movement that supports Trump's Health Sec. Robert F. Kennedy Jr., have criticised the Trump administration's backing of Bayer. A number of groups from the agricultural and crop farming industries also supported Bayer. Durnell was supported by several environmental, farm worker, and public health organizations.
