Supreme Court Releases 4 Opinions, Including 7-2 Roundup Pre-emption Ruling
3 articles · Updated · SCOTUSblog · Jun 25
Summary
The Supreme Court on Thursday issued opinions in four cases: Mullin v. Doe, Wolford v. Lopez, Mullin v. Al Otro Lado, and Monsanto Company v. Durnell.
In Durnell, the justices overturned a $1.25 million Missouri jury award against Bayer in a 7-2 ruling, holding federal pesticide law pre-empts state-law cancer warning claims over Roundup.
Justice Brett Kavanaugh wrote that EPA-approved labeling for Roundup conflicts with state requirements to add cancer warnings, shielding Bayer from that category of claims.
The Durnell decision could reshape thousands of pending Roundup lawsuits against Bayer, which acquired Monsanto in 2018 and has faced billions in potential glyphosate liability.
How will this ruling affect the proposed $7.25 billion settlement for thousands of existing Roundup cancer lawsuits?
With federal law overriding state warnings, what recourse do consumers have if they believe a product caused them harm?

Supreme Court Shields Monsanto/Bayer from Roundup Failure-to-Warn Lawsuits: Key Ruling Reshapes Liability for 170,000+ Claims and $7.25 Billion Settlement
Overview
On June 25, 2026, the U.S. Supreme Court issued a major 7-2 decision siding with Monsanto/Bayer, holding that federal law—the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)—overrides state-level requirements for warning labels on Roundup. The Court adopted the position of the U.S. Solicitor General, John Sauer, making it clear that if Roundup’s labeling meets federal standards, plaintiffs cannot win state court claims that Monsanto failed to warn about cancer risks. This ruling sets a strong legal precedent, sharply limiting Monsanto/Bayer’s liability for failure-to-warn lawsuits and reshaping the legal landscape for similar cases nationwide.
