Supreme Court to review Bayer's bid to halt Roundup cancer lawsuits
The Supreme Court has stepped into a high-stakes legal battle over Bayer’s popular weedkiller, Roundup, with a decision that could impact thousands of cancer-related lawsuits.
On Friday, the Supreme Court agreed to hear an appeal from Germany-based agrochemical giant Bayer, which seeks to block numerous state lawsuits claiming the company failed to warn users that Roundup could cause cancer.
The court will examine whether the Environmental Protection Agency’s approval of Roundup without a cancer warning preempts these state-level failure-to-warn claims. Bayer, which acquired Roundup maker Monsanto in 2018, argues for federal protection against the ongoing litigation.
The debate has ignited sharp divisions, with the Trump administration supporting Bayer’s position, a reversal from the Biden administration’s stance. This shift has frustrated some aligned with the Make America Healthy Again agenda, who oppose granting Bayer legal immunity. Environmental groups, meanwhile, contend that Bayer is dodging accountability in state courts where it often loses.
Bayer’s Legal Strategy Under Scrutiny
Bayer faces around 181,000 claims, mostly from residential users, despite having set aside $16 billion to settle cases, the AP reports. The company disputes the cancer allegations, pointing to the EPA’s finding that glyphosate, Roundup’s key ingredient, is not likely carcinogenic when used as directed. Yet, some studies link glyphosate to cancer, fueling the legal firestorm.
The company has also pushed states to pass laws barring such lawsuits, with Georgia and North Dakota already complying. Bayer has warned it might pull glyphosate from U.S. agricultural markets if the litigation persists, a move that could disrupt farming practices tied to genetically modified crops like corn and soybeans. These crops rely on glyphosate to boost yields while reducing soil tillage.
In a Missouri case the Supreme Court will review, a jury awarded $1.25 million to a man who developed non-Hodgkin’s lymphoma after using Roundup in a St. Louis community garden. This contrasts with a 2022 decision when the court declined to hear a similar California case, where a couple received over $86 million. Lower courts, like the 3rd U.S. Circuit Court of Appeals in 2024, have issued conflicting rulings, prompting Bayer’s plea for clarity.
Political and Environmental Tensions Rise
Bayer’s CEO, Bill Anderson, has framed this as a matter of legal fairness. “It is time for the U.S. legal system to establish that companies should not be punished under state laws for complying with federal warning label requirements,” Anderson said. But let’s be real—hiding behind federal rules feels like a slick way to sidestep accountability when juries keep ruling against you.
Environmental advocates aren’t buying Bayer’s argument either. “It’s a sad day in America when our highest court agrees to consider depriving thousands of Roundup users suffering from cancer of their day in court,” said Lori Ann Burd, environmental health director at the Center for Biological Diversity. If Bayer’s so confident in its product, why does it seem terrified of facing everyday Americans in a jury box?
The political flip-flop adds another layer of frustration. The Trump administration’s backing of Bayer clashes with a movement that claims to champion health and transparency over corporate interests. This isn’t about punishing businesses; it’s about ensuring they don’t get a free pass when real lives are at stake.
Health Concerns Versus Agricultural Needs
Health concerns over glyphosate persist, even as Bayer has stopped using it in U.S. residential lawn and garden products while keeping it in agricultural ones. The science remains disputed, with the EPA’s stance clashing against studies suggesting a cancer link. Americans deserve straight answers, not a bureaucratic shield for a product tied to so much uncertainty.
Farmers, on the other hand, rely on glyphosate for efficient, soil-friendly production with genetically modified seeds. Pulling it from agricultural markets could hit food supply chains hard, a reality Bayer seems to wield as leverage. But should economic convenience trump potential health risks?
The Supreme Court’s timing is unclear, with arguments possibly set for spring or the next term in October. Until then, thousands of plaintiffs wait for justice, caught between a corporate giant and a federal agency’s word. This case isn’t just about weedkiller—it’s about who gets to decide what’s safe.
What’s at Stake for Everyday Americans
Environmental groups argue Bayer wants to keep juries out of the equation because state courts often side with victims. If the Supreme Court rules in Bayer’s favor, it could slam the door on accountability for countless individuals claiming harm. That’s not justice; it’s a rigged game.
This isn’t about being anti-business—it’s about fairness. If a product might cause harm, shouldn’t those affected have a voice, not just a corporate memo from the EPA? The Supreme Court’s decision will signal whether federal overreach or personal rights win out in America’s legal landscape.
