The U.S. Supreme Court has requested input from the Justice Department regarding Bayer’s appeal against litigation tied to its Roundup herbicide, a glyphosate product alleged to cause cancer. Bayer seeks a ruling affirming federal preemption or curbing large-scale injunctions, aiming to limit liability and stabilize settlement exposure.
Numerous lawsuits have accused Roundup of contributing to non-Hodgkin lymphoma, resulting in multi-billion‑dollar verdicts and indemnity obligations. Bayer has set aside over $16 billion to settle cases but is pursuing legal avenues to narrow future liability. The company’s petition raises federal preemption arguments, claiming that Environmental Protection Agency registration of the herbicide should shield it from state‑level tort claims.
The Supreme Court’s request for the government’s views (amicus curiae) suggests potential review at the term beginning in October 2025. A favorable precedent could forestall further lawsuits and impose uniform national standards, while a decision against Bayer may reinforce state-level litigation paths.
If the high court accepts review and limits state claims, it could cap Bayer’s exposure and set a pathway for corporate protection against simultaneous state and federal regulation conflicts. Conversely, maintaining current legal allowances could preserve plaintiffs’ ability to pursue class claims and state judicial remedies, raising implications for similar products.

Bayer’s appeal addresses the tension between regulatory review and judicial action. A Supreme Court decision could reshape liability risk for agrochemical products nationwide. While corporate interests favor uniform standards, plaintiffs rely on state-level redress for harm claims. The outcome must weigh regulatory authority against consumer protection.
