Supreme Court backs Monsanto in landmark Roundup case, reshaping global pesticide debates

The U.S. Supreme Court ruled 7–2 in favor of Monsanto owner Bayer, holding that federal pesticide law preempts state-level claims requiring additional cancer warnings on Roundup, significantly reducing Bayer’s litigation risk and reinforcing the primacy of federal regulators like the EPA. The decision is expected to lead to dismissal of most existing lawsuits and limit future claims, while shifting debates about glyphosate safety from courtrooms to regulatory arenas. While industry groups praised the clarity and regulatory certainty provided by the ruling, critics argued it undermines accountability and restricts legal recourse for those alleging harm, fueling ongoing controversy over glyphosate’s safety and broader questions about the balance between regulatory authority and public trust in agricultural policy.
