The US Supreme Court rules 7-2 that the Federal Insecticide, Fungicide, and Rodenticide Act preempts state lawsuits claiming Roundup failed to warn consumers about cancer risks, blocking thousands of claims.The Court sides with Bayer, which bought Monsanto for $63B, after the Environmental Protection Agency repeatedly found glyphosate unlikely to cause cancer and reversed a $1.25M jury verdict for John Durnell.The decision narrows avenues for failure-to-warn claims against other pesticide makers, including Syngenta over paraquat, and leaves Bayer facing more than 100K suits despite $16B set aside and a proposed $7.25B settlement.The ruling deepens a split between US public-health regulators and international bodies, with the
EPA clearing glyphosate while the International Agency for Research on Cancer classed it as probably carcinogenic, and plaintiffs warn it reduces accountability for long-term exposure claims.
