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

The U.S. Supreme Court ruled on Friday that it would hear Bayer’s request to limit lawsuits claiming the Roundup weedkiller caused cancer. This could potentially save billions of dollars in damages.

The justices heard Bayer's appeal against 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 upheld a $1.25-million verdict awarded by a St. Louis juror to the plaintiff John Durnell over his cancer diagnosis.

Bayer's shares rose almost 5% after the news broke that the court will hear the case. The court has not yet announced when it will hear arguments.

Bill Anderson, CEO of Bayer, said in a statement that the court's ruling was "an important part of our multi-pronged approach to effectively contain this litigation."

Anderson stated that it was time to ensure that state laws do not punish companies for adhering to federal warning label requirements.

A request for comment from an attorney of the plaintiff was not immediately responded to.

The Missouri Court of Appeals has rejected the German pharmaceutical company's argument that federal law governing chemicals bars claims made under state laws.

Bayer faces similar claims in state and federal court proceedings in the United States from about?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 brief submitted to the court, 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 should not be allowed to sue the company under state law because it failed to warn them that Roundup increased cancer risk, as the U.S. Environmental Protection Agency found no such risk. Bayer argued federal law prohibits it from adding any warning to its product beyond that approved by the EPA.

The company's strategy for managing the claims has been to make the U.S. Supreme Court an important part of it, since a ruling that federal laws preempt claims brought under state laws would close down the vast majority.

Durnell's lawyers had asked that the Supreme Court dismiss Bayer’s appeal. Durnell's lawyers argued that Durnell relied heavily on Bayer advertising, not just the label, when he decided to use Roundup. They also claimed the marketing of Bayer failed to warn the public about the risks.

The company paid $10 billion in settlements to most Roundup lawsuits pending by 2020. However, it failed to reach a deal that would cover future cases. Since then, new lawsuits continue to flood in. Plaintiffs claim they developed non-Hodgkin lymphoma or other cancers after using Roundup at home, on the job or in their garden.

Bayer, who acquired Roundup in 2018 as part of the $63 billion acquisition of Monsanto, an agrochemicals company, has stated that studies over decades have proven Roundup, and its active ingredient glyphosate are safe for use by humans.

Sauer stated in the brief of the administration to the Supreme Court that "EPA has repeatedly 'determined that glyphosate does not appear to be carcinogenic to humans. And the agency has approved Roundup labels which did not include '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, such as a $2.1 Billion verdict in Georgia, U.S.A. in 2025.

Bayer had asked the Supreme Court in the past to review the Roundup litigation, but it was denied by the court in 2022. In a break from other appeals judges, a federal appeals court has sided with Bayer since then.

Bayer has threatened withdrawal of Roundup from the U.S. Market as it battles the litigation. Bayer replaced glyphosate with other weed-killing chemicals in its U.S. consumer product line.
