US Supreme Court will hear Bayer's request to limit Roundup cases

The U.S. Supreme Court has agreed to hear Bayer’s request to limit lawsuits claiming the Roundup weedkiller caused cancer. This could potentially save billions of dollars and prevent millions of dollars in damages.

The justices heard Bayer's appeal of a lower-court ruling in a case filed by a man who claimed he had been diagnosed with non-Hodgkin lymphoma following years of exposure Roundup.

The Missouri Court of Appeals has rejected the German pharmaceutical &?biotechnology firm's argument that federal law governing insecticides prohibits lawsuits relating to pesticides brought under state laws.

Bayer faces similar claims in state and federal courts in the United States from 65,000 plaintiffs. Roundup is one of the most commonly used weedkillers across the United States. In December, the administration of President Donald Trump urged Supreme Court to hear Bayer's appeal. U.S. In a court brief, U.S. D. John Sauer, the Solicitor-General of the United States, stated that Bayer's interpretation of the relevant law is correct.

Bayer argues that consumers shouldn't be able sue the company under state law because it failed to warn them that Roundup "increases cancer risks" as the U.S. Environmental Protection Agency found no such risk, and therefore did not require a warning. Bayer argued federal law did not allow them to 'add any warnings to the product other than the EPA approved label.

The U.S. Supreme Court is a crucial part of the company's strategy to manage claims. A ruling that federal law preempts state-law claims would end the vast majority. Monsanto stated that different courts have taken opposing sides on the issue.

The Missouri Court of Appeals has upheld a $1.25-million verdict awarded by a St. Louis Jury to plaintiff John Durnell for his cancer diagnosis.

Durnell's lawyers had asked the Supreme Court not to hear Bayer’s appeal. Durnell's lawyers argued that Durnell relied heavily on Bayer's advertisements and not only the label to make his decision to use Roundup. They also claimed the marketing of the company failed to warn the public about the risks.

The company paid $10 billion in order to settle the majority of Roundup lawsuits as of 2020. However, it failed to reach a settlement that would cover future cases. Since then, new lawsuits continue to be filed. Plaintiffs claim they have developed non-Hodgkin lymphoma or other cancers after using Roundup at home or in the workplace.

Bayer, who acquired Roundup as part of its $63 Billion purchase of Monsanto, an agrochemicals company in 2018, said that studies over decades have proven Roundup, and its active ingredient glyphosate are "safe for human usage".

Sauer, in the brief of the administration to the Supreme Court, said: "EPA has repeatedly determined glyphosate does not cause cancer in humans. The agency has approved Roundup labels without cancer warnings."

The company's record in court has been mixed. Bayer has won a number of Roundup lawsuits, but in recent years it's also been hit with large jury verdicts, including $2.1 billion in a 2025?case from the U.S. State of Georgia. Bayer had asked the Supreme Court in the past to take the Roundup litigation into consideration, but it was rejected by the court in 2022. In a break from other appeals judges, a federal appeals court has sided with Bayer since then. Bayer has warned that it will withdraw Roundup products from the U.S. marketplace as it battles the lawsuit. In the U.S., the company has replaced glyphosate with other weed-killing chemicals.
