Supreme Court Weighs Whether Federal Law Shields Bayer From Roundup Cancer Suits

The decision will test whether EPA-approved labels block state warning claims, a choice that could reset Roundup litigation.

Overview

  • Following Monday’s oral arguments, the justices appeared split on Bayer’s bid to bar failure‑to‑warn lawsuits over Roundup, with a ruling expected by the end of June.
  • At issue is federal preemption under the pesticide law known as FIFRA, which requires EPA‑approved labels and bars states from imposing different label rules, even as a WHO agency labeled glyphosate “probably carcinogenic” in 2015 and the EPA has not required a cancer warning.
  • The case stems from John Durnell’s Missouri verdict, where a jury awarded $1.25 million after finding Monsanto failed to warn that long‑term Roundup use could cause non‑Hodgkin lymphoma.
  • A win for Bayer could knock out many state failure‑to‑warn claims but leave other theories intact, while a proposed $7.25 billion settlement that won preliminary approval in March awaits a July fairness hearing.
  • Trump’s administration urged the Court to side with Bayer, drawing protests from MAHA‑aligned activists and others outside the Court, as farm groups warned that limits on glyphosate could raise costs and strain the food supply.
