U.S. Supreme Court blocks state Roundup warnings, reshaping pesticide lawsuits

On June 25 2026 the U.S. Supreme Court issued a ruling in Monsanto Company v. Durnell that state‑law labeling requirements that differ from those approved by the Environmental Protection Agency are pre‑empted under the Federal Insecticide, Fungicide, and Rodenticide Act. The decision overturns earlier state‑law claims that Monsanto failed to warn consumers about cancer risks from Roundup, a glyphosate‑based herbicide, and is expected to reshape the litigation landscape for pesticide products. The case followed a Missouri jury award of about $1.25 million for a failure‑to‑warn claim. In a separate development, a North Carolina federal jury found an Uber driver liable for battery, awarding $5,000 in damages, adding to a multidistrict litigation that includes more than 3,100 cases alleging Uber’s negligence in driver assaults.
