Supreme Court Blocks Roundup Failure-to-Warn Lawsuits
6/25/2026, 9:38:35 PM
Decision and Legal Reasoning
On June 25 the Court ruled 7-2 that FIFRA precludes failure-to-warn suits against Bayer’s Roundup. Justice Brett Kavanaugh’s majority held EPA-approved labels, which lack a cancer warning, must be used unless the agency changes them. Justice Ketanji Brown Jackson, joined by Justice Neil Gorsuch, dissented, saying the decision “unjustifiably closes the courthouse doors” to plaintiffs like John Durnell.
Background
Glyphosate was labeled “probably carcinogenic” by the WHO’s IARC in 2015, while the EPA finds it “not likely to cause cancer” when used as directed. Bayer bought Monsanto in 2018 for $63 billion, inheriting over 100,000 lawsuits. A Missouri jury awarded Durnell $1.25 million; Bayer has set aside $16 billion and proposed a $7.25 billion settlement.
Key Figures & Stakeholders
Principal actors are plaintiff John Durnell, Bayer AG (owner of Monsanto), Justices Kavanaugh and Jackson, the EPA, the Modern Ag Alliance, and the MAHA coalition.
Data & Statistics
Over 100,000 plaintiffs have filed about 200,000 claims. Bayer’s $7.25 billion settlement proposal and an 18 % share rise follow the ruling; EPA reports 280 million pounds of glyphosate on 300 million acres.
Official Statements & Responses
Bayer said the ruling “is good for science, farmers, and industries that depend on regulatory clarity for innovation” and would “significantly contain the Roundup litigation.” Tino Andresen said it should dismiss warning-based claims. The Justice Department argued EPA’s review justifies the label; Paul Clement noted Congress wanted uniform warnings.
Criticism & Opposition
Environmental groups say the decision shields Bayer. Tarah Heinzen of Food and Water Watch called it a public-health disaster; Kelly Ryerson warned it could worsen cancer and chronic disease rates. Vani Hari of MAHA called the ruling dangerous.
Conflicting Reports & Gaps
The WHO’s IARC calls glyphosate “probably carcinogenic,” while the EPA finds it “not likely to be carcinogenic.” EPA’s next comprehensive review is slated for later this year, leaving consensus unresolved.
Verbatim Quotes
- “This Supreme Court ruling wrongly slams the courthouse door on Americans sickened by pesticides,” — Christopher Seeger, attorney.
- “Once again, the Supreme Court has sided with big business over people and the environment.” — Tarah Heinzen, Food and Water Watch.
- “Congress plainly wanted uniformity when it came to the safety warnings on a pesticide's label,” — Paul Clement, Bayer counsel.
What’s Next
The $7.25 billion settlement now awaits Missouri state-court approval. The EPA will finish its glyphosate safety review later this year, and Congress members have introduced bills to limit pesticide liability. Future plaintiffs may still bring design-related claims, but the Supreme Court’s preemption makes such suits far harder.
