He developed a cancer called non-Hodgkin’s lymphoma after more than 20 years of serving as the neighborhood association’s “spray guy,” using Roundup on parks in his historic St. Louis community.\n\nA jury agreed that the company failed to warn him about possible cancer dangers and awarded him $1.25 million. It’s one of thousands of similar cases, including some multibillion-dollar damage awards.\n\nThere’s still fierce debate about cancer and Roundup’s key ingredient, glyphosate. The World Health Organization’s International Agency for Research on Cancer classified the chemical as “probably carcinogenic” in 2015. The Environmental Protection Agency has determined that it’s not likely to cause cancer in humans when used as directed.\n\nThe agency approved a label without a cancer warning, and Bayer argues that it’s required to follow those federal standards — not the state laws that Durnell and others have sued under. The ruling could allow other suits alleging problems with the way the product was designed, his attorney Ashley Keller has said.\n\nBayer disputes the cancer claims but previously set aside $16 billion to settle cases, and earlier this year proposed a $7.25 billion class-action settlement to resolve many of the remaining claims. A federal judge recently ruled that the proposed settlement will be heard in a Missouri state court, where many of the lawsuits have been filed. At the same time, the company has tried to persuade states to pass [laws shielding it from liability](https://apnews.com/article/bayer-roundup-pesticide-cancer-lawsuits-35a9e6d8773b5145c920d919a28fdb83) in failure-to-warn lawsuits, and three states have agreed.\n\nAbout 200,000 Roundup-related claims have been made against Bayer, mostly from home users. It has stopped using glyphosate in Roundup sold in the U.S. residential lawn and garden market.\n\nThe company has said it might have to consider pulling glyphosate from U.S. agricultural markets if it keeps getting sued. Agricultural industry group say could have a devastating effect on the food supply.\n\nBut pesticides have also created a rift between the Trump administration and members of Health Secretary Robert F. Kennedy’s MAHA movement, adding to their frustration with an executive order aimed at boosting glyphosate’s production.\n\nKennedy himself has said repeatedly that glyphosate causes cancer, even as he says he recognizes the executive order was necessary for food supply and national security reasons.", "url": "https://wpnews.pro/news/supreme-court-ruling-blocks-thousands-of-lawsuits-against-maker-of-roundup", "canonical_source": "https://www.mercurynews.com/2026/06/25/supreme-court-ruling-blocks-thousands-of-lawsuits-against-maker-of-roundup-weedkiller-2-2/", "published_at": "2026-06-25 14:08:52+00:00", "updated_at": "2026-06-25 14:15:21.773480+00:00", "lang": "en", "topics": ["ai-policy"], "entities": ["Supreme Court", "Bayer", "Monsanto", "Roundup", "Environmental Protection Agency", "Robert F.
