Corporate Greed Case Study: Roundup from Monsanto / Bayer and Its Impact on Peter Engilis
The Human Story: A 25-Year Routine Ends in a Cancer Diagnosis
For 25 years, from 1990 to 2015, Peter Engilis, Jr. did what countless homeowners do. He routinely sprayed the herbicide Roundup at his three homes in Florida, trusting the product on the shelf. But in 2014, that routine was shattered by a diagnosis of chronic lymphocytic leukemia (CLL), a type of blood cancer.
For Peter and his wife Cathy, this was not some random ass tragedy.
They believed there was a direct line between his years of exposure to Monsanto’s flagship product and the cancer that had invaded his body.
They decided to fight back, filing a lawsuit against the chemical giant in a battle that would reveal less about the science of cancer and more about the power of a corporation to control the narrative of harm in a court of law.
Monsanto is owned by Bayer, who is in my opinion the most evil company in the whole world.
The Corporate Playbook: How the Harm Was Done
To win a case like this, a family like the Engilises must prove that Roundup was not only capable of causing cancer in general, but that it specifically caused Peter’s cancer. To do this, they hired Dr. Andrew Schneider, a board-certified oncologist, to provide the crucial expert opinion linking the chemical to the disease. Dr. Schneider prepared a detailed report arguing that after ruling out other potential causes, Roundup was the most likely culprit behind Peter’s illness.
Monsanto’s strategy was not to debate the merits of the case in front of a jury. Instead, it was to ensure a jury never heard the evidence at all. Monsanto’s lawyers launched a targeted attack on Dr. Schneider’s credibility and his scientific method. Their goal was simple: get his opinion thrown out of court. If they could disqualify the expert, the Engilises’ case would collapse, and Monsanto would walk away without ever having to defend the safety of Roundup itself.
Absolutely despicable.
I wonder how these shitbag corporate lawyers sleep at night knowing that this is their contribution to the world. What do their children think of them, I wonder?
A Cascade of Consequences: The Real-World Impact
Public Health & Safety
The true consequence of this case lies not in legal arguments, but in the silencing of a scientific opinion. Monsanto’s lawyers zeroed in on a single alternative risk factor for Peter’s cancer: obesity. They argued that Dr. Schneider did not do enough to scientifically disprove that Peter’s weight, rather than their product, was the cause of his non-Hodgkin’s lymphoma.
During a court hearing, Monsanto’s counsel presented medical records suggesting Peter’s Body Mass Index (BMI) qualified him as obese. Under cross-examination, Dr. Schneider admitted he could not definitively say whether Peter was obese or not. He also attempted to argue that, based on his decades of clinical experience, he did not believe obesity was a significant risk factor for this type of cancer anyway, stating he saw “fat people get CLL” and “skinny people get CLL”.
The court found this was not enough. It decided that Dr. Schneider’s failure to adequately address and eliminate obesity as a potential cause in his written report made his entire analysis unreliable. His opinion was excluded. With their only evidence of causation gone, the Engilises’ case was over.
The court granted summary judgment for Monsanto, and the company was absolved of any responsibility.
A System Designed for This: Profit, Deregulation, and Power
This case is a stark illustration of how our legal and economic system—often described as neoliberal capitalism—is structured to protect corporate interests over public health. The relentless pursuit of profit necessitates aggressive legal strategies designed to minimize liability and externalize costs, with the human cost of illness being one such externality.
Monsanto, a multi-billion dollar corporation, possesses virtually unlimited resources to litigate. It can afford to hire teams of lawyers to scrutinize every word of an expert report and exploit any perceived weakness.
An ordinary family like the Engilises is immediately at a disadvantage. The legal standard for admitting expert testimony, known as the Daubert standard, requires a judge to act as a “gatekeeper” to ensure scientific evidence is reliable. While intended to keep “junk science” out of the courtroom, this case shows how corporations can weaponize this standard.
They can transform the process into a prohibitively expensive and complex mini-trial focused on an expert’s methodology, rather than the substance of their claims. By creating a cloud of doubt around a single data point—in this case, obesity—Monsanto rendered the entire body of expert analysis inadmissible.
This is a feature of a system where legal and regulatory frameworks favor those with the most capital. The burden of proof falls squarely on the injured party, a monumental task when pitted against a corporate giant whose business model depends on denying such links.
Dodging Accountability: How the Powerful Evade Justice
The outcome for Monsanto was a total victory. There was no settlement, no admission of guilt, and no jury verdict. Monsanto (Bayer) didn’t have to prove Roundup was safe; it only had to prove the Engilises’ expert wasn’t perfect. By excluding Dr. Schneider’s testimony, the court effectively decided the case without ever hearing its merits.
This is a classic example of accountability being sidestepped through legal procedure.
The court’s decision was not about whether Roundup caused Peter Engilis’s cancer. Instead, it was about whether his expert followed the correct scientific and legal procedures for ruling out alternative causes.
For Monsanto, this is simply the cost of doing business—a legal expense that protects a multi-billion dollar product line. For the Engilis family, it was the end of their quest for justice.
Reclaiming Power: Pathways to Real Change
This case demonstrates the urgent need for systemic reforms that rebalance the scales of justice between individuals and powerful corporations. Potential pathways to change include:
- Reforming Expert Testimony Standards: Lawmakers could consider adjusting the standards for expert testimony in toxic tort cases, recognizing the inherent difficulty of proving specific causation for diseases with multiple risk factors. This could prevent corporations from having entire cases dismissed on narrow methodological challenges.
- Shifting the Burden of Proof: For products known to carry significant risks, the burden could be shifted to corporations to prove their products did not cause the harm once a plausible link has been established. This would incentivize more rigorous pre-market safety testing and corporate transparency.
- Empowering Regulatory Agencies: Strengthening the funding and authority of agencies like the EPA would ensure that product safety is determined by independent scientific bodies rather than being fought out case-by-case in the court system, where resources often dictate the outcome.
Conclusion: A Story of a System, Not an Exception
The story of Peter and Cathy Engilis is a window into a much larger crisis of corporate accountability.
It demonstrates how the modern economic and legal system is often designed to produce such outcomes, where procedural victories for corporations translate into devastating losses for individuals.
This single court document reveals a system where justice can be too expensive to secure and too complex to prove, leaving the powerful unaccountable and ordinary people to bear the cost.
