The collection of documents known as The Monsanto Papers represents one of the most significant exposures of corporate malfeasance in modern history. These internal documents, numbering in the millions of pages and obtained by Wisner Baum (formerly Baum Hedlund Aristei & Goldman) through legal discovery, reveal a systematic, decades-long campaign by the agrochemical giant to manipulate scientific research, corrupt regulatory processes, and deceive the public about the safety of its flagship herbicide, Roundup.
The Monsanto Papers tell an alarming story of ghostwriting, scientific manipulation, regulatory capture, coordinated attacks on independent scientists, and the creation of sophisticated intelligence operations targeting journalists and activists. These documents, which Monsanto fought to keep secret, provide unprecedented insight into how a powerful corporation systematically undermined scientific integrity and public health protections.
Wisner Baum distinguished itself as one of the few law firms committed to bringing the Monsanto Papers into the public domain, employing a strategic and proactive transparency approach that was, and still is, unique in corporate litigation. Working in collaboration with the Plaintiffs' Steering Committee in the federal multidistrict litigation, the firm utilized the protective order provisions to systematically challenge Monsanto's confidentiality designations, sending a detailed 28-page chart that challenged dozens of specific internal company documents.
When Monsanto refused to engage meaningfully in the meet-and-confer process and told the attorneys to "go away," Wisner Baum recognized that the company had failed to file the required motion within 30 days to preserve confidentiality, automatically waiving protection under Paragraph 16.3 of the Protective Order. This strategic legal maneuvering, led by attorney R. Brent Wisner, resulted in the first major declassification of internal Monsanto documents on August 1, 2017.
Beyond merely winning legal battles over document access, our firm remained deeply committed to public transparency by proactively sharing the declassified documents with journalists, key regulatory agencies, and international lawmakers. We sent documents to the EPA Office of Inspector General investigating potential collusion between EPA and Monsanto, California's Office of Environmental Health Hazard Assessment (OEHHA), which had listed glyphosate as a carcinogen, and European Parliament members who were considering glyphosate's registration renewal in the European Union.
Attorneys R. Brent Wisner and Michael Baum traveled to Brussels to personally brief Members of Parliament and provide testimony to EU committees, while continuing to systematically release additional document batches over a period of years.
Ultimately, our firm has made available hundreds of documents that reveal corporate ghostwriting, regulatory capture, and systematic attacks on independent science. Our transparency-first approach, which we believe is essential because the public, regulatory agencies, and scientists need to see what happens behind the curtain of corporate unaccountability, helped make Wisner Baum a leader in using mass tort litigation discovery as a tool for broader corporate accountability.
The documents reveal not isolated incidents of misconduct, but a coordinated, multi-decade strategy that extended from academic journals to government agencies. Internal communications show company executives directly involved in strategies to manipulate scientific literature and regulatory processes, demonstrating how corporate resources were deployed to shape public discourse about product safety.
The papers expose extensive ghostwriting practices where Monsanto employees or contractors wrote scientific articles published under the names of supposedly independent researchers. The most prominent example involved a 2000 publication by Williams et al. that has been frequently cited as evidence of glyphosate's safety, but internal emails revealed that Monsanto scientists had substantially drafted the manuscript while external authors received primary credit.
Among the most disturbing revelations were extensive coordination between Monsanto and officials at the Environmental Protection Agency (EPA). Internal emails revealed a particularly troubling relationship with Jess Rowland, a senior EPA official leading the agency's assessment of glyphosate's cancer risk, who coordinated with Monsanto to suppress independent safety reviews.
The documents revealed the creation of Monsanto's "Intelligence Fusion Center" - a sophisticated monitoring operation that tracked journalists, activists, and scientists critical of the company. This intelligence gathering extended to personal character assassination campaigns, mirroring tactics used by the tobacco industry to attack scientists studying smoking-related health risks.
The Monsanto Papers exposed fundamental vulnerabilities in:
These revelations provided a blueprint for understanding how corporate influence operates in practice, offering crucial lessons for protecting scientific independence and strengthening regulatory oversight.
The Monsanto Papers continue to serve as a defining case study in corporate accountability and the ongoing struggle to maintain scientific integrity in an era of powerful commercial interests. They demonstrate both the sophisticated methods by which corporations can manipulate public discourse and the crucial role of legal discovery in exposing such misconduct.
As new documents were published through litigation, the Monsanto Papers became a vital resource for understanding the intersection of corporate power, scientific integrity, and public health protection. Today, they underscore the importance of maintaining transparent, independent research institutions and robust regulatory oversight to protect public welfare from corporate influence campaigns.
March 13, 2017: U.S. District Judge Vince Chhabria ruled that certain documents obtained by plaintiffs in the Monsanto Roundup multidistrict (MDL) litigation could be unsealed. Subsequently, the judge published them on March 14 and March 15 on the website for the U.S. District Court for the Northern District of California. These were the very first evidence to be declassified.
June 30, 2017: Our firm, along with the leadership of the Roundup multidistrict litigation (MDL), challenged the protection of another group of documents, in an effort to make them available to the public. In a meeting to discuss the matter, Monsanto told the plaintiffs’ attorneys to “go away” and that the company would not voluntarily agree to de-designate any documents.
Pursuant to Paragraph 16.3 of the Protective Order in the MDL, Monsanto was required to file a motion seeking continued protection of those documents challenged by the Plaintiffs’ June 30, 2017 letter within 30 days. In failing to file such motion within 30 days, i.e., July 31, 2017, Monsanto “automatically waive[s] the confidentiality designation for each challenged designation.” Id. ¶ 16.3. And, since Monsanto did not file any motion seeking continued protection of the documents, it waived confidentiality over them.
August 1, 2017: A second group of documents are now officially public, and our attorneys are excited to share them with the world.
We sent the August 2017 batch of Monsanto secret documents to (1) the EPA Office of Inspector General, Arthur Elkins, Jr., who is presently investigating whether there was illegal collusion between EPA and Monsanto; (2) the California’s Office of Environmental Health Hazard Assessment (OEHHA), which listed glyphosate as a substance known to the state of California to cause cancer on July 7, 2017 and is soliciting comments from our law firm and others to advise about whether glyphosate should be given a safe-harbor; and (3) the European Parliament members, who, on July 4, 2017, sent a letter to the judge overseeing the MDL litigation, requesting documents as the EU considers whether it will renew registration of glyphosate for sale in Europe.
April 24, 2019: Our attorneys released a new batch of 300+ declassified documents obtained during discovery. We also added several new categories. Since 2017, our firm has added more than 400 documents to the Monsanto Papers. All Monsanto Papers documents can be viewed in our Master Chart at the top of this page.
August 15, 2019: We released our third batch of documents. These documents reveal Monsanto’s efforts to defund IARC, their involvement with Reuter’s reporter Kate Kelland, the creation of their ‘Intelligence Fusion Center’ targeting journalists and activists critical of Monsanto, and more about their manipulating science.

"Wisner Baum gave exceptional attention to all aspects of the case, detailed inquiry, and tenacious overview of all the information submitted. The paralegals are efficient and diligent. I was completely surprised to find an empathic personal message to take care of my own health during the challenging time of being a full-time caretaker.*"
In May of 2019, the jury in the case of Pilliod et al. v, Monsanto Company ordered the agrochemical giant to pay $2.055 billion in damages to the plaintiffs, Alva and Alberta Pilliod, a Bay Area couple in their 70s. R. Brent Wisner served as co-lead trial attorney for the Pilliods, delivering the opening and closing statements and cross-examining several of Monsanto’s experts. Wisner Baum managing shareholder, Michael Baum and attorney Pedram Esfandiary also served on the trial team in the Pilliod case.
The judge later reduced their award to $87M. Monsanto appealed the Pilliod’s verdict which the California Court of Appeal for the First Appellate District denied on August 9, 2021. Monsanto then requested the California Supreme Court review the appeal’s court decision, which the court denied on Nov. 17, 2021. Monsanto (Bayer) then submitted a petition for a writ of certiorari with the U.S. Supreme Court which SCOTUS denied on June 27, 2022, allowing the final judgment of $87M to remain intact.
$289.2 million jury verdict in Monsanto Roundup trial
Wisner Baum co-represented Dewayne “Lee” Johnson in the first Roundup cancer lawsuit to proceed to trial. On Aug. 10, 2018, a San Francisco jury ordered Monsanto to pay $39.25 million in compensatory damages and $250 million in punitive damages to Mr. Johnson, a former groundskeeper who alleged exposure to Monsanto’s herbicides caused him to develop terminal non-Hodgkin lymphoma.
Months after the jury verdict, the judge overseeing the trial reduced the punitive damages to $39.25 million. Mr. Johnson decided to accept the remittitur, bringing the adjusted amount awarded to Mr. Johnson $78.5 million.
Monsanto (Bayer) appealed the verdict and Johnson cross appealed. On July 20, 2020, the First Circuit Court of Appeals upheld the verdict against Monsanto but reduced Mr. Johnson’s award to $20.5 million. The company chose not to take the case to the U.S. Supreme Court, ending the litigation.
In 2016, Wisner Baum attorney Timothy A. Loranger and six other attorneys in the Plaintiffs’ Management Committee were able to secure a $265 million settlement for victims of the 2015 Amtrak 188 derailment in Philadelphia, one of the largest in the U.S. for 2016.
