Missouri Roundup Ruling: What the Supreme Court’s 7-2 Monsanto Decision Means for Your Glyphosate Cancer Claim
If you used Roundup for years and then heard the words “non-Hodgkin lymphoma” from an oncologist, you probably started looking into a lawsuit. And then you saw the news: the United States Supreme Court just handed Monsanto a 7-2 victory, ruling that the company cannot be sued in state court for failing to warn about cancer risks on its Roundup label. Your first thought was probably: is my case dead?
We are Attorney911 — The Manginello Law Firm, PLLC. We are toxic tort lawyers who take Missouri cases, and we are writing this page for one person: the Missouri resident, farmer, groundskeeper, or homeowner who used Roundup, developed non-Hodgkin lymphoma, and now does not know whether they still have a legal path. The honest answer is more complicated than a headline — and more complicated than the chemical company’s victory lap suggests. The main road is blocked. But the main road was never the only road, and the people who tell you “it’s over” are the same people who wanted it over before you ever walked into a courtroom.
The Supreme Court Just Ruled 7-2 for Monsanto — Here Is What That Actually Means
The Supreme Court held that the Federal Insecticide, Fungicide, and Rodenticide Act — known as FIFRA — preempts state-law failure-to-warn claims about pesticide labels when the Environmental Protection Agency has not required the warning the plaintiff is seeking. In plain English: because the EPA decided in 2020 that glyphosate is “unlikely to be carcinogenic” and did not require Monsanto to put a cancer warning on Roundup’s label, state courts cannot force Monsanto to pay for not putting that warning on the label.
This is a real and significant ruling. It eliminates the single most successful theory that Roundup plaintiffs had used to win verdicts across the country — the claim that Monsanto failed to warn consumers about a cancer risk it knew or should have known about. That theory produced jury verdicts in Missouri, California, and other states. It is now, as a failure-to-warn theory, preempted nationwide by federal law.
But here is what the ruling did not do. It did not find that glyphosate is safe. It did not find that Roundup does not cause cancer. It did not find that Monsanto is immune from all liability. It did not address claims that are not based on the label’s warnings — and those claims, in some form, may still exist. The Supreme Court answered one question: does FIFRA block state-court failure-to-warn lawsuits when EPA has not required the warning? The answer was yes, 7-2. Every other question — design defect, fraud, independent negligence, what Monsanto knew and when — was left for another day, another theory, or another court.
The Durnell Case: How a Missouri Man’s Jury Verdict Became the Vehicle for a National Preemption Ruling
The case the Supreme Court decided came from Missouri. John Durnell, a Missouri resident, sued Monsanto in 2019, alleging that two decades of using Roundup caused his non-Hodgkin lymphoma. A Missouri jury sided with him in 2023 — a fact-finder heard the evidence, weighed the science, and concluded that Roundup use caused his cancer. That jury verdict was a critical validation: a group of citizens found specific causation, that this man’s cancer was caused by this product.
Then the Supreme Court took the case. The question was not whether Roundup caused Mr. Durnell’s cancer. The question was whether Monsanto could be sued in state court at all for failing to warn about that risk. The Court said no — FIFRA preempts the claim because the EPA did not require a cancer warning.
“If Make America Healthy Again is going to mean anything, it has to apply consistently, not just when it’s politically convenient, but also when powerful political interests and corporate interests are involved as well.”
The ruling’s practical effect in Missouri is immediate and severe. Missouri state courts — particularly in St. Louis City and surrounding counties, which had been among the most favorable venues in the country for Roundup plaintiffs — can no longer hear failure-to-warn claims against Monsanto. The primary litigation pathway that produced significant verdicts in Missouri is closed. But the Missouri tort system still permits strict liability claims against product manufacturers with no statutory damage caps in toxic tort cases, and state-specific design-defect and fraud theories remain theoretically available, subject to further preemption analysis.
How FIFRA Preemption Works — and Why the EPA’s 2020 Finding Was the Key That Locked the Door
FIFRA is the federal law that governs pesticide registration, labeling, and sale in the United States. Under FIFRA, the EPA must approve every pesticide label before the product can be distributed. The EPA reviews the active ingredients, the proposed uses, and the safety data, and it determines what warnings and precautions the label must carry. Once the EPA approves a label, that label becomes a federal requirement — the manufacturer must use exactly that label, and states cannot impose different or additional labeling requirements.
In 2020, the EPA completed an interim registration review of glyphosate and concluded that it is “unlikely to be carcinogenic to humans.” Because of that finding, the EPA did not require Monsanto to include a cancer warning on Roundup’s label. The Supreme Court held that this federal regulatory determination — that no cancer warning is required — simultaneously shields the manufacturer from state tort claims that would impose one.
The structural barrier is this: the EPA’s determination that no cancer warning is needed is, under the Court’s reasoning, a federal requirement that state courts cannot contradict. A state-court jury verdict finding that Monsanto should have warned about cancer would, in effect, impose a state requirement different from the federal one — and FIFRA says that is not allowed. The same regulatory system that was supposed to protect consumers has now been turned into the shield that protects the manufacturer from being held accountable in state court for the missing warning.
But the EPA’s finding is not immutable. The EPA can reconsider its classification. New scientific studies can prompt a re-evaluation. And Congress can change the law — which is exactly what some legislators are now trying to do.
Which Roundup Claims Are Eliminated vs. Potentially Still Viable
This is the question every person with a Roundup case is asking. Here is the honest map:
Eliminated by the Supreme Court ruling:
Failure-to-warn claims under state law are preempted nationwide. If your case is premised solely on the theory that Monsanto should have put a cancer warning on the Roundup label and failed to do so, that theory is now blocked by federal preemption. This was the primary and most successful theory in Roundup litigation. For cases built only on this theory, the case value is effectively zero absent legislative reversal or a new legal theory.
Potentially surviving — though uncertain and actively contested:
Design-defect claims that argue Roundup is unreasonably dangerous by design — not by labeling — may survive preemption. The theory would be that the product itself is defective because glyphosate is inherently dangerous, regardless of what the label says. Courts will scrutinize whether a design-defect theory is genuinely about the product’s design or is merely a disguised failure-to-warn claim. The viability of this theory is uncertain and will be litigated case by case.
Independent negligence claims based on Monsanto’s alleged conduct beyond labeling — manipulation of scientific research, suppression of adverse findings, or improper influence over the EPA regulatory process — may constitute negligence or fraud that is not directly premised on failure to warn. If Monsanto made affirmative misrepresentations about glyphosate safety beyond mere silence on the label, those claims may fall outside FIFRA preemption.
Fraud and misrepresentation claims may survive if they are based on affirmative false statements rather than on the label’s contents. The distinction matters: failing to warn is passive; affirmatively lying is active. The Monsanto Papers — internal documents obtained through prior Roundup discovery that allegedly show the company manipulated scientific literature, ghostwrote regulatory submissions, and influenced the EPA’s review process — are the evidence that could power these surviving theories.
Every one of these alternative theories is uncertain. The Supreme Court’s ruling did not explicitly address them, and lower courts will now have to decide whether preemption extends beyond failure-to-warn to design defect, fraud, and independent negligence. Until further judicial development clarifies which theories survive, the case-value landscape for new Roundup filings is severely depressed compared to what it was before the ruling.
Design Defect, Fraud, and Independent Negligence: The Alternative Theories Explained
For the reader who wants to understand what a surviving Roundup case might actually look like, here is how each alternative theory would work:
Design defect — The claim is not that the label was inadequate but that the product itself is unreasonably dangerous. Glyphosate, the argument goes, is a chemical whose risks outweigh its benefits when used as directed, and a reasonable alternative formulation or approach existed. The defense will argue that this is just failure-to-warn wearing a disguise — that the real complaint is still “you didn’t tell us it causes cancer.” The plaintiff’s counter is that the design of the product — putting a probable human carcinogen in a consumer weedkiller sold at every hardware store in America without adequate safety testing or safeguards — is itself the defect, independent of any label. Whether courts accept this framing is an open question that will be fought in motions to dismiss across the country.
Independent negligence — The claim is that Monsanto’s conduct beyond the label was independently wrongful. Internal documents from prior Roundup litigation — the so-called Monsanto Papers — allegedly show that the company engaged in a coordinated campaign to manipulate the scientific record on glyphosate’s carcinogenicity, ghostwrote scientific papers that were then cited to regulators, and worked to influence the EPA’s review process. If proved, this conduct is not a labeling failure — it is an independent wrong that caused harm by distorting the regulatory process and the public’s understanding of the risk. The defense will argue that FIFRA preemption extends to any claim that depends on the adequacy of the EPA-approved label, even if framed as independent negligence. The plaintiff’s counter is that fraud upon a regulator is not a labeling claim — it is an independent tort that preceded and corrupted the labeling process.
Fraud and misrepresentation — The claim is that Monsanto made affirmative false statements about glyphosate’s safety. Not silence — lies. The distinction between “you should have warned” and “you lied” is legally significant. A failure-to-warn claim says the defendant was passive and should have spoken. A fraud claim says the defendant was active and spoke falsely. If the Monsanto Papers show that Monsanto publicly represented glyphosate as safe while internally acknowledging evidence of carcinogenicity, those affirmative misrepresentations may support fraud claims that fall outside FIFRA’s preemption scope. The defense will argue that any fraud claim that depends on what the label should have said is still preempted. The plaintiff’s counter is that a company that actively misled regulators and the public committed a wrong that is distinct from — and independent of — whatever the label ultimately said.
Each of these theories is a real legal argument that a skilled toxic tort lawyer would explore. None of them is a guaranteed path to recovery. The honest framing is this: the Supreme Court closed the main road, and the side roads are narrow, uncertain, and being contested in real time. But they exist, and a lawyer who understands toxic tort litigation at the federal preemption level is the one who can tell you whether your specific facts fit any of them.
The Legislative Response: Congress Is Trying to Reopen the Door
The Supreme Court’s ruling is a judicial decision — but Congress can change the statute the Court interpreted. And members of Congress from both parties are already trying.
A Democratic senator has announced plans to introduce an amendment to the Senate version of the farm bill that would strip pesticide companies of the preemption shield the Supreme Court just created. A parallel effort has already occurred in the House, and a Republican representative has announced a standalone bill with the same goal. The proposed legislation would remove FIFRA’s preemptive authority over state-law failure-to-warn claims, returning to the people the right to hold pesticide manufacturers accountable in state court for the harm their products cause.
Whether this legislation passes is uncertain. It faces opposition from the agricultural lobby, the chemical industry, and members of Congress who support the preemption shield. But the political backlash to the Supreme Court ruling — from environmental groups, public health advocates, and the “Make America Healthy Again” movement — has created an unusual bipartisan coalition that may have the political force to push reform through.
What this means for you: if you have a Roundup exposure and a non-Hodgkin lymphoma diagnosis, the legal landscape is not frozen. It is shifting. Legislation could reopen the failure-to-warn pathway. New scientific studies could prompt the EPA to reconsider its glyphosate classification. Further litigation could clarify which alternative theories survive preemption. None of these developments is guaranteed — but none of them requires you to have already filed. What they require is that your evidence is preserved, your medical records are complete, and your exposure history is documented while you wait to see how the law develops.
Monsanto and Bayer: The Company Behind Roundup
Monsanto Company is now a wholly-owned subsidiary of Bayer AG, the German pharmaceutical and chemical conglomerate. Bayer acquired Monsanto in 2018 for approximately $63 billion — and inherited a massive litigation portfolio that has cost Bayer billions in settlements and verdicts. The caption defendant in Roundup cases is still “Monsanto Company,” but the financial responsibility and strategic decision-making sit with the German parent.
Bayer has taken the position that glyphosate “remains the most studied crop protection tool in the world” and that the Supreme Court ruling “restores the regulatory clarity that the agricultural sector, the broader food supply chain, and American consumers deserve.”
“glyphosate remains the most studied crop protection tool in the world”
The federal Roundup litigation was consolidated as MDL-2741, In re: Roundup Products Liability Litigation, in the Northern District of California before Judge Vince Chhabria. As of the most recent Judicial Panel on Multidistrict Litigation report, approximately 3,900 actions were pending in the MDL — a number that has declined as cases resolved but that reflects the scale of the litigation that the Supreme Court’s ruling now disrupts.
Bayer previously entered into a settlement framework covering certain Roundup claims, but that settlement did not cover all plaintiffs, and new cases continued to be filed. The Supreme Court’s preemption ruling changes the calculus for every unresolved case and every potential new filing. Bayer’s strategy now is clear: use the preemption ruling to seek dismissal of failure-to-warn claims nationwide, while fighting alternative theories on the argument that FIFRA preemption extends to them as well.
The Monsanto Papers — internal corporate documents obtained through discovery in prior Roundup litigation — are partially public and are the single most important evidence for any surviving theory. These documents allegedly include internal communications about glyphosate’s carcinogenicity, evidence of scientific-publication manipulation, ghostwriting of regulatory submissions, and efforts to influence the EPA’s review process. They are the raw material for fraud and independent-negligence claims, and they are already available, in part, through prior litigation. Preserving and cataloging them for use in surviving-theory pleadings is a task that begins now, not after a court clarifies which theories survive.
The Medicine: Non-Hodgkin Lymphoma and Glyphosate Exposure
Non-Hodgkin lymphoma is a cancer of the lymphatic system — specifically of the lymphocytes, the white blood cells that help the body fight infection. It is not one disease but a group of more than 70 subtypes, ranging from indolent (slow-growing) to aggressive (fast-growing). The diagnosis changes everything: the subtype, the stage, the treatment protocol, and the prognosis all determine what the patient’s life looks like from the day of diagnosis forward.
Treatment — Depending on the subtype and stage, treatment regimens may include R-CHOP chemotherapy (a combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone), radiation therapy, immunotherapy, targeted therapies, and in some cases stem cell transplants. Each of these carries its own side-effect profile: nausea, hair loss, fatigue, immune suppression, neuropathy, cardiac toxicity, secondary cancer risk, and graft-versus-host disease for transplant patients. Treatment can last months to years, and surveillance continues for life.
Cost — Lifetime treatment costs for non-Hodgkin lymphoma frequently exceed several hundred thousand dollars, and in cases requiring stem cell transplantation, the costs can push past a million dollars. These figures do not include lost wages, diminished earning capacity, or the human cost — the fear, the pain, the relationships strained, the life plans upended.
The science — The International Agency for Research on Cancer, which is the World Health Organization’s cancer-research arm, classified glyphosate as “probably carcinogenic to humans” (Group 2A) in 2015. The EPA’s 2020 finding that glyphosate is “unlikely to be carcinogenic” reached the opposite conclusion. This conflict between the world’s leading cancer research authority and the U.S. environmental regulator is not a minor academic disagreement — it is the fault line that runs through every Roundup case. The EPA’s position is what drove the Supreme Court’s preemption ruling. The IARC’s position is what gives plaintiffs a causation argument. And several peer-reviewed studies, including a major study published last year, have found a link between glyphosate exposure and non-Hodgkin lymphoma.
The proof problem — Non-Hodgkin lymphoma has multiple causes and no single signature the way mesothelioma is essentially specific to asbestos. The defense exploits this: they argue that the cancer was idiopathic, caused by age, genetics, or background environmental factors unrelated to Roundup. The plaintiff’s counter is dose reconstruction — documenting the duration, frequency, and extent of glyphosate exposure through purchase receipts, usage logs, employment records, and witness testimony — combined with the scientific literature showing an elevated risk of NHL in individuals with significant glyphosate exposure. The Durnell jury in 2023 found this evidence sufficient to establish specific causation: that two decades of Roundup use caused Mr. Durnell’s cancer. That finding remains significant even though the Supreme Court reversed on the preemption question — the causation evidence was strong enough to convince a jury, and that evidence does not disappear because the legal theory it was attached to has been preempted.
What Your Case May Be Worth After This Ruling
We are going to be honest with you, because honesty is what a person in crisis needs from a lawyer — not a sales pitch.
For cases premised solely on failure-to-warn: the Supreme Court’s 7-2 preemption ruling has effectively eliminated the cause of action. Case value for a pure failure-to-warn claim is now effectively zero absent legislative reversal. The primary and most successful theory of liability in Roundup litigation is gone.
For cases that can plead viable design-defect, fraud, or independent-negligence theories: pre-ruling comparable verdicts ranged from multi-million-dollar to nine-figure awards. But the preemption analysis may extend to these theories, and no court has yet confirmed which survive. Case value for these theories is uncertain and theory-dependent — potentially significant if the theory survives preemption, potentially zero if it does not.
If the proposed federal legislation passes — the amendments to strip pesticide companies of the preemption shield — state-court failure-to-warn claims could be restored, potentially reviving the full case-value landscape. This is a political possibility, not a legal certainty.
The damages framework, if a viable theory is established, would include: economic losses (past and future medical expenses, lost wages, diminished earning capacity), non-economic damages (pain and suffering, loss of quality of life, emotional distress), and potentially punitive damages based on allegations that Monsanto manipulated scientific literature and regulatory processes. Missouri has no statutory damage caps in toxic tort cases, which means a jury could award the full measure of damages without a statutory ceiling reducing the award — if a viable theory gets you to a jury in the first place.
The honest bottom line: we cannot tell you what your case is worth today, because the law is in flux. What we can tell you is that the evidence that would support any surviving theory — your exposure history, your medical records, your purchase receipts — is the same evidence that would have supported a failure-to-warn claim, and it is perishable. The question is not just “what is my case worth?” It is “is my evidence still alive by the time the law clarifies?”
How to Preserve Evidence for Future Claims While the Legal Landscape Evolves
The evidence that supports any Roundup claim — whether failure-to-warn, design defect, fraud, or independent negligence — is the same evidence, and much of it is on a clock. Here is what exists, who holds it, and how fast it can disappear.
Roundup purchase receipts, product containers, and usage logs — These establish the duration, frequency, and extent of your glyphosate exposure, which is the foundation of specific causation in any surviving theory. Receipts may be in your personal records, credit card statements, or store accounts. Physical product containers should be preserved indefinitely — they are evidence of the formulation and labeling you were exposed to. If you still have Roundup containers in your garage or shed, do not throw them away. Photograph them. Store them.
Complete medical records — Your non-Hodgkin lymphoma diagnosis, pathology reports, treatment history, and oncologist’s causation opinions prove your injury, its mechanism, and your damages. Obtain copies of everything — diagnosis reports, biopsy results, treatment plans, chemotherapy records, imaging, blood work, and any opinion your oncologist has expressed about the cause of your cancer. Hospitals operate on record-retention policies that can legally permit destruction of records after a set period. Get your copies before any provider’s record-destruction policy applies.
Occupational and residential exposure history — If you used Roundup as a groundskeeper, farmer, landscaper, agricultural worker, or homeowner, the documentation of that exposure — employment records, job descriptions, product-purchase histories, witness statements from coworkers or family members who saw you use the product — establishes the exposure pathway and cumulative dose. Memory degrades. Witnesses relocate. Employment records get purged. Document this now, while the details are fresh and the people who can confirm them are reachable.
Monsanto Papers and internal corporate documents — Internal Monsanto/Bayer documents obtained through prior Roundup discovery may support fraud, misrepresentation, or independent-negligence theories that could survive preemption. These documents are already partially public through prior litigation. They show what the company knew about glyphosate’s potential carcinogenicity and when — and they are the evidence that could power the surviving theories. If you are considering a claim, a lawyer who is already familiar with the Monsanto Papers can assess whether your specific exposure and diagnosis fit a theory that those documents support.
The preservation principle is the same one that governs every toxic tort case: the evidence that proves your exposure and your injury is the evidence that disappears first. Purchase receipts get discarded. Memory fades. Witnesses move. Medical records get purged on retention schedules. The day you call a lawyer is the day the evidence-preservation clock starts working for you instead of against you.
The Defense Playbook: What Monsanto and Bayer Will Do Now
The Supreme Court ruling gives Monsanto and Bayer a powerful new tool, and they will use it aggressively. Here is what to expect — and the counter to each play.
Play 1: Move to dismiss every Roundup case on preemption grounds. Bayer will file motions to dismiss in every pending and new Roundup case, arguing that FIFRA preemption bars not just failure-to-warn claims but any claim that depends on the adequacy of the EPA-approved label. The counter: distinguish failure-to-warn from design defect, fraud, and independent negligence. The Supreme Court addressed failure-to-warn. It did not address — and did not preempt — claims based on the product’s design, the company’s affirmative misrepresentations, or its independent wrongful conduct in manipulating the regulatory process.
Play 2: Deploy the EPA’s “unlikely carcinogenic” finding as a Daubert challenge to causation experts. Bayer will argue that your expert witnesses cannot reliably testify that glyphosate causes non-Hodgkin lymphoma because the EPA — the federal regulator — concluded it is unlikely to be carcinogenic. The counter: the IARC classified glyphosate as probably carcinogenic (Group 2A), multiple peer-reviewed studies support the association, and the EPA’s finding is a regulatory determination, not a scientific consensus. Expert witnesses must be prepared to defend general causation under the jurisdiction’s expert-admissibility standard, anticipating that the EPA finding will be used to challenge their methodology and reliability.
Play 3: Frame every alternative theory as a disguised failure-to-warn claim. Bayer will argue that design-defect claims, fraud claims, and independent-negligence claims are all just failure-to-warn wearing different clothes — and that if failure-to-warn is preempted, so are they. The counter: the distinction between passive silence (failure to warn) and active misconduct (affirmative misrepresentation, scientific manipulation, regulatory fraud) is a real legal distinction that courts recognize. The Monsanto Papers — if they show what prior discovery suggests they show — are evidence of active misconduct, not passive silence.
Play 4: Run out the clock on the statute of limitations. Bayer will delay, oppose, and litigate every procedural question, betting that the statute of limitations will expire before the legal landscape clarifies. The counter: file early, preserve evidence, and argue that the discovery rule tolls the limitations period for latent diseases where the connection between exposure and illness was not known or reasonably discoverable until diagnosis. Missouri’s statute of limitations for personal injury claims — including toxic tort and product liability claims — is five years under Missouri’s general personal injury statute. For latent diseases like cancer caused by chemical exposure, the discovery rule typically means the clock starts when you knew or should have known that your illness was connected to the exposure — not when you first used the product. But this is a state-specific question that a licensed attorney in Missouri must confirm for your specific situation.
Play 5: Settle cheap, citing the ruling. Bayer may offer low settlements to current plaintiffs, arguing that the Supreme Court ruling has destroyed their cases. The counter: the ruling eliminated one theory, not all theories. A case with strong exposure evidence, a clear NHL diagnosis, and facts that fit a surviving theory is not worth zero — and settling for pennies on the dollar because one legal door closed, while others remain contested, is a decision that should be made with full information about what alternatives exist.
How a Surviving Roundup Case Is Actually Built
If a viable theory can be identified for your case, here is how it would be built — step by step, from the day you call to the day a number is on the table.
Week one: preservation. The preservation letter goes out to Monsanto/Bayer and any other relevant parties, demanding that they freeze internal documents, communications, regulatory submissions, and scientific-research records related to glyphosate. On your side, we collect every piece of evidence of your Roundup exposure — receipts, containers, photos, employment records, witness statements — and your complete medical record from diagnosis forward. Everything gets organized, cataloged, and stored.
Early motion practice: the preemption battleground. The first major fight is whether your specific complaint survives a motion to dismiss based on FIFRA preemption. This is where the distinction between failure-to-warn (preempted) and design defect, fraud, or independent negligence (potentially not preempted) is tested. The complaint must be drafted with precision — each count must be grounded in a theory that is distinguishable from failure-to-warn, supported by facts that show active misconduct rather than passive silence, and backed by the Monsanto Papers where they exist.
Discovery: what Monsanto knew and when. If the complaint survives, discovery targets Monsanto/Bayer internal communications about glyphosate carcinogenicity, scientific-publication manipulation, ghostwriting of regulatory submissions, and EPA-influence efforts. The Monsanto Papers already partially public give a roadmap for what to demand. Discovery also targets the EPA’s regulatory file — communications between Monsanto and the agency, submissions, and the basis for the 2020 “unlikely carcinogenic” finding.
Expert witnesses: defending general causation. Expert witnesses must be prepared to defend the general causation link between glyphosate and non-Hodgkin lymphoma under the jurisdiction’s expert-admissibility standard. They must anticipate that the EPA’s “unlikely carcinogenic” finding will be deployed as a Daubert challenge. The counter is the IARC Group 2A classification, the peer-reviewed studies showing an association, and the methodological criticism of the EPA’s review process — including evidence that Monsanto influenced that process.
Specific causation: linking your exposure to your cancer. Your specific causation case is built from your exposure history (duration, frequency, and extent of Roundup use), your medical records (NHL diagnosis, subtype, absence of other obvious causes), and expert testimony applying the general causation science to your specific dose and timeline. The Durnell jury found this sufficient in 2023. The evidence that convinced that jury does not disappear because the Supreme Court reversed on a preemption question.
Damages: the lifetime arithmetic. A life-care planner builds the cost stream — past and future medical treatment, ongoing surveillance, medication, and any future care needs. A forensic economist reduces it to present value. Lost earning capacity is calculated from your work history, education, and the impact of the diagnosis on your ability to work. Non-economic damages — pain, suffering, loss of quality of life — are proven through your testimony, your family’s testimony, and the medical record’s documentation of what treatment has been and what lies ahead.
Voir dire: managing the ruling’s shadow. In any surviving state-court case, jury selection must address juror awareness of the Supreme Court ruling and the EPA position. Jurors who believe “the government said it’s safe, so it must be safe” are not going to hear your case fairly. The voir dire strategy must identify and address preconceptions about regulatory endorsement of glyphosate safety without suggesting that the EPA is corrupt — a delicate balance that requires a trial lawyer who understands how to educate a jury about regulatory capture without losing credibility.
What to Do If You Used Roundup and Were Diagnosed With Non-Hodgkin Lymphoma
If you are reading this page and you have a non-Hodgkin lymphoma diagnosis and a history of Roundup use, here is what you should do — and what you should not do — right now.
Do:
Gather every piece of evidence of your Roundup use. Receipts. Containers. Photos of the product in your garage or shed. Employment records if you used it at work. Statements from people who saw you use it. The duration and frequency of your use — how many years, how often, how much — is the foundation of any claim that might survive, and that information is most accurate when it is documented now, not years from now.
Get your complete medical records. Your diagnosis, your pathology reports, your treatment history, your oncologist’s notes — everything. Obtain copies before any provider’s record-retention policy permits destruction. If your oncologist has expressed an opinion about the cause of your cancer, get it in writing.
Document your exposure history in writing. Write down — or have a family member help you write down — every job, every season, every property where you used Roundup, how often, and for how many years. Memory degrades. Witnesses move. The written record you create today is stronger than the recalled record you try to reconstruct in two years.
Talk to a lawyer who understands toxic tort litigation at the federal preemption level. Not every personal injury lawyer understands FIFRA preemption or the distinction between failure-to-warn and the surviving alternative theories. The lawyer who tells you “your case is dead” without analyzing whether your facts fit a design-defect, fraud, or independent-negligence theory is not giving you complete information. The lawyer who tells you “your case is worth millions” without honestly acknowledging the preemption ruling’s impact is not giving you complete information either. You need the lawyer who tells you the truth: the main road is closed, the side roads are uncertain, and whether your specific facts fit any of them is a question that requires careful analysis.
Do not:
Do not throw away Roundup containers, receipts, or any physical evidence of your use. Do not post on social media about your diagnosis, your lawsuit plans, or your Roundup use — defense investigators monitor social media, and posts can be taken out of context. Do not give a recorded statement to any insurance representative, claims adjuster, or investigator — for Monsanto, for Bayer, or for any other party — without speaking to a lawyer first. Do not sign any release, settlement, or waiver without having a lawyer review it. And do not wait. The statute of limitations is running, the evidence is degrading, and the legal landscape is shifting — all three of those clocks are moving, and none of them is moving in your favor.
Missouri’s Legal Landscape for Toxic Tort Claims
Missouri has historically been one of the most favorable states in the country for toxic tort plaintiffs. The state’s tort system has produced substantial plaintiff verdicts in pesticide and pharmaceutical cases, and St. Louis City and surrounding counties were preferred venues for Roundup litigation before the Supreme Court’s preemption ruling. Missouri has no statutory damage caps in toxic tort cases, meaning a jury could award the full measure of damages — economic and non-economic — without a statutory ceiling reducing the recovery.
Missouri’s statute of limitations for personal injury claims, including toxic tort and product liability claims, is five years under Missouri’s general personal injury statute — one of the longer limitations periods in the United States. For latent diseases like cancer caused by chemical exposure, the discovery rule typically applies, meaning the clock may start when the plaintiff knew or reasonably should have known that the illness was connected to the exposure, rather than when the product was first used. This is particularly important for glyphosate cases, where the latency between exposure and cancer diagnosis can span decades.
Missouri follows a comparative-fault system in which your own share of fault reduces, and at a certain threshold can bar, your recovery. The specific bar threshold is a state-specific rule that has been the subject of recent legislative change in Missouri — confirm the current standard with a licensed Missouri attorney. In a Roundup case, comparative fault is less likely to be a major factor (you used a consumer product as directed), but the defense may argue that you failed to follow label instructions or used the product excessively.
The Supreme Court’s FIFRA preemption ruling overrides Missouri state law on failure-to-warn claims — this is a federal ruling that applies nationwide, regardless of Missouri’s tort-friendly traditions. But Missouri’s favorable evidentiary rules, its lack of damage caps, and its plaintiff-friendly venue history remain relevant for any surviving theories that are not preempted. If a design-defect, fraud, or independent-negligence theory can be established and survives a preemption challenge, the Missouri tort framework that made it a preferred venue for Roundup plaintiffs is still available for the damages phase.
Frequently Asked Questions
Can I still sue Monsanto if I used Roundup and got non-Hodgkin lymphoma?
The primary theory — failure-to-warn — is now preempted by the Supreme Court’s 7-2 ruling, meaning you generally cannot sue Monsanto in state court for failing to put a cancer warning on the Roundup label. However, alternative theories including design defect, fraud, and independent negligence may survive preemption, depending on how courts interpret the ruling’s scope. Whether your specific facts fit any surviving theory is a question that requires analysis by a lawyer who understands FIFRA preemption and toxic tort litigation.
Is my existing Roundup case dead because of the Supreme Court ruling?
If your case is premised solely on failure-to-warn, the Supreme Court ruling has effectively eliminated your cause of action. Your lawyer should be evaluating whether your complaint can be amended to include design-defect, fraud, or independent-negligence theories that may survive preemption. If your case includes those theories already, it may continue — but expect Monsanto to file motions to dismiss arguing that those theories are also preempted. Each case’s survival depends on its specific claims, the jurisdiction, and how courts interpret the ruling’s reach.
What is the statute of limitations for a Roundup cancer claim in Missouri?
Missouri’s statute of limitations for personal injury claims, including toxic tort and product liability claims, is five years. For latent diseases like cancer caused by chemical exposure, the discovery rule may mean the clock starts when you knew or should have known that your illness was connected to the exposure — potentially the date of diagnosis, not the date you first used Roundup. Confirm the current deadline for your specific situation with a licensed Missouri attorney, because the limitations period is a hard deadline that cannot be extended.
What evidence do I need to preserve for a Roundup claim?
Preserve every piece of evidence that documents your Roundup use and your cancer diagnosis: purchase receipts, product containers, usage logs, employment records (if you used Roundup at work), witness statements from people who saw you use it, your complete medical records including pathology reports and treatment history, and any opinion your oncologist has expressed about causation. Physical product containers should be preserved indefinitely. Medical records should be obtained before any provider’s record-destruction policy applies. Document your exposure history in writing now, while details are fresh.
What is the Monsanto Papers and how do they affect my case?
The Monsanto Papers are internal corporate documents obtained through discovery in prior Roundup litigation that allegedly show Monsanto manipulated scientific literature on glyphosate’s carcinogenicity, ghostwrote regulatory submissions, and influenced the EPA’s review process. These documents are central to fraud and independent-negligence theories that may survive the Supreme Court’s preemption ruling because they show active misconduct — not just passive failure to warn. They are partially public through prior litigation and may be available for use in new pleadings built on surviving theories.
Is Congress going to fix the preemption ruling?
Members of Congress from both parties have announced legislative efforts to strip pesticide companies of the preemption shield created by the Supreme Court ruling. A Democratic senator has proposed a farm-bill amendment, and a Republican representative has announced a standalone bill. Whether this legislation passes depends on political dynamics that are uncertain. If it passes, state-court failure-to-warn claims could be restored. If it does not, the alternative-theory path remains the primary route for Roundup plaintiffs. Monitor these developments, but do not rely on legislation as your only hope — preserve your evidence and explore surviving theories now.
How much is a Roundup cancer case worth after the Supreme Court ruling?
For cases premised solely on failure-to-warn, case value is effectively zero absent legislative reversal. For cases that can establish viable design-defect, fraud, or independent-negligence theories, pre-ruling comparable verdicts ranged from multi-million-dollar to nine-figure awards, but the preemption analysis may extend to these theories and no court has confirmed which survive. The damages framework — if a viable theory gets you to a jury — includes economic losses (medical expenses, lost wages, diminished earning capacity), non-economic damages (pain and suffering, loss of quality of life), and potentially punitive damages. Missouri has no statutory damage caps in toxic tort cases. Honest case valuation requires knowing which theory your facts support and whether that theory survives preemption — both of which are currently uncertain.
Should I wait to see if the law changes before contacting a lawyer?
No. The evidence that supports any Roundup claim — your exposure history, your medical records, your purchase receipts — is the same evidence regardless of which legal theory applies, and it is perishable. Memory degrades, witnesses relocate, medical records get purged, and physical evidence gets discarded. The statute of limitations is running. The legal landscape is shifting, but your evidence is degrading faster than the law is clarifying. The day you call a lawyer is the day the evidence-preservation clock starts working for you instead of against you. Waiting is the one decision that cannot be undone.
Why Attorney911
Ralph Manginello has spent 27-plus years in courtrooms, including federal court. He was a journalist before he was a lawyer — which means he reads a Supreme Court opinion the way most lawyers read a brief, and he explains it to a client the way most lawyers never bother to. Ralph built this firm on the principle that a person in crisis deserves the truth before they get a pitch, and the truth about the Supreme Court’s Roundup ruling is more complicated than “your case is over” and more honest than “your case is worth millions.”
Lupe Peña spent years inside a national insurance-defense firm — the rooms where adjusters and their software decided how to deny, delay, and devalue claims exactly like yours. He sat across the table from the people who build the defenses that plaintiffs face. Now he sits on your side of the table. Lupe knows how the defense evaluates a toxic tort claim, how they deploy regulatory findings like the EPA’s “unlikely carcinogenic” determination to challenge causation, and how they use preemption rulings to push for dismissal. He uses that inside knowledge for injured clients. He is fluent in Spanish and conducts full consultations in Spanish without an interpreter.
We are a Texas-based trial firm that takes Missouri cases, working with local counsel and pro hac vice admission where required. We do not claim an office in Missouri, and we do not pretend to be something we are not. What we are is a firm that understands FIFRA preemption, toxic tort litigation, and the difference between a case that is dead and a case that is wounded but breathing. The Supreme Court closed a door. Whether another one is open for you is a question we answer honestly, after looking at your specific facts — not before.
We handle these cases on contingency. That means we do not get paid unless we win your case. The consultation is free. The call is confidential. And the conversation will be honest — about what the ruling means, about what may survive, about what your evidence looks like, and about whether pursuing a claim makes sense for your family.
Past results depend on the facts of each case and do not guarantee future outcomes. The firm has recovered more than $50 million for clients, including $5 million-plus in a brain-injury settlement and $3.8 million-plus in an amputation settlement — but those results were earned on specific facts in specific cases, and the Supreme Court’s Roundup ruling has changed the legal landscape for glyphosate claims. We will tell you exactly where you stand.
Hablamos Español. Lupe conducts full client consultations in Spanish without an interpreter, and our staff is bilingual. If your family communicates in Spanish, you will be heard in Spanish — from the first call to the last day of your case.
Call 1-888-ATTY-911 — 24 hours a day, 7 days a week, with live staff, not an answering service. Or contact us online. The consultation is free. There is no fee unless we win your case. And if we are not the right fit for your situation — if the law has truly closed every door for your specific facts — we will tell you that, too, and we will tell you why. That is what a lawyer is supposed to do. It is what we do.
If you want to understand more about how case value works in injury law, Ralph explains it here. If you are worried about what happens if a case does not succeed, that question is answered here. The legal landscape for Roundup claims has changed — but your right to understand your options, to get an honest evaluation, and to make an informed decision about your family’s future has not.
