Supreme Court shuts down thousands of lawsuits that claim Roundup weedkiller might cause cancer
The 7-2 ruling says federal labeling rules bar state failure-to-warn claims, a decision expected to affect about 200,000 Roundup-related claims.
- The U.S. Supreme Court ruled 7–2 on Thursday in favor of Monsanto , dealing a massive legal victory to the agrochemical giant by heavily restricting the ability of cancer patients to sue over the weedkiller Roundup.
- The landmark decision establishes that federal regulation overrides state law, with Justice Brett Kavanaugh writing for the majority that because the EPA evaluated glyphosate and explicitly determined it does not require a cancer warning, state-level "failure to warn" lawsuits are legally preempted.
- The ruling severely handicaps a wave of roughly 200,000 product liability claims, shutting the door on tens of thousands of pending lawsuits filed by home users and groundskeepers who allege they developed non-Hodgkin lymphoma from the product.
- The case centered on Missouri resident John Durnell, who was awarded $1.25 million by a state jury in 2023 after using Roundup for over two decades to beautify local parks; Thursday’s high court decision effectively invalidates those state court findings.
- The decision creates a complex political rift for the Trump administration, as the ruling aligns with the administration's business deregulation goals but severely frustrates Health Secretary Robert F. Kennedy Jr. and the "Make America Healthy Again" movement, which has fiercely campaigned to outlaw glyphosate.

The Bayer Group won a victory in the U.S. Supreme Court in the legal dispute over the alleged cancer risks of its weed destroyer with the active substance glyphosate. According to the ruling, Bayer cannot be sued for lack of cancer warnings on packaging of weed destroyers.
The complaints were based on the alleged risk of cancer from Roundup herbicide. The U.S. Supreme Court ruled that Bayer could not be blamed for not placing an additional health warning on his products.
U.S. Supreme Court ruling blocks thousands of lawsuits against maker of Roundup weedkiller
The U.S. Supreme Court sided with the maker of the Roundup weedkiller Thursday in a ruling expected to block thousands of lawsuits alleging it failed to warn people the product could cause cancer.
On Thursday, 25 June, the judges estimated that the agri-food giant could not be convicted for the absence of additional health warnings on its products, as the US Federal Environmental Protection Agency did not impose any alerts on the carcinogenic potential of the Roundup.
Seven of the nine judges considered that the manufacturer could not be accused of not placing an additional health warning on its products.
