Dewayne Johnson v. Monsanto Company | California State Court

Dewayne Johnson v. Monsanto

Dewayne Johnson v. Monsanto Company is the first Roundup cancer lawsuit to proceed to trial. The lawsuit alleges exposure to Monsanto’s Roundup weed killer and its active ingredient, glyphosate, caused Northern California resident Dewayne “Lee” Johnson to develop non-Hodgkin lymphoma (NHL).

Quick link to trial transcripts and exhibits

Lee Johnson worked as a groundskeeper for the Benicia Unified School District in the San Francisco Bay Area. Between 2012 and 2015, part of Mr. Johnson’s job was to apply Monsanto herbicides to school properties.

In 2014, Lee began to experience severe skin irritation, which he reported to health care providers. He also contacted Monsanto, asking if his skin irritation could have been caused by his use of Roundup. Internal Monsanto emails later obtained by Lee’s attorneys show that his queries concerning Roundup were discussed among company employees. However, Monsanto never responded to Mr. Johnson, so he continued to use Roundup.

In August of 2014, Lee was diagnosed with epidermotropic T-cell lymphoma. After his diagnosis, his job still required him to apply and be in close contact with Monsanto glyphosate-based herbicides. Despite enduring chemotherapy treatments throughout 2015, Mr. Johnson’s cancer progressed. In September 2017, a biopsy revealed mycosis fungoides (non-Hodgkin lymphoma with large cell transformation).

Mr. Johnson filed a Roundup cancer lawsuit against Monsanto in 2016. He is represented by the Miller Firm and Baum, Hedlund, Aristei & Goldman.

Order on Deposition Designations and Certain Proposed Jury Instructions(23 pages) (5.17.18) – Judge rules plaintiffs can present punitive damages in CA State Court case DEWAYNE JOHNSON vs. MONSANTO COMPANY, ET AL. Deposition designations start on page 17. Rulings are in limine and so subject to review by trial judge as the trial progresses.

Order on (1) Monsanto’s Omnibus Sargon Motion; (2) Monsanto’s Motion for Summary Judgment; (3) Plaintiff’s Omnibus Sargon Motion; (4) Plaintiff’s Motion for Summary Adjudication (48 pages) (5.17.18) – Judge issues ruling in CA State Court case DEWAYNE JOHNSON vs. MONSANTO COMPANY, ET AL.

  1. Monsanto’s Omnibus Sargon Motion: The judge ruled to exclude Dr. Portier’s pooling analysis and any conclusions that depend on it, Dr. Sawyer’s water permeability test and cancer slope opinions, certain testimony from Dr. Benbrook and Dr. Mills’ opinion as to total lost income. Otherwise motion was denied.
  1. Monsanto’s Motion for Summary Judgment and Adjudication: The motions were denied.
  1. Plaintiff’s Omnibus Sargon Motion: The judge ruled to exclude Dr. Rider’s opinion that the epidemiological evidence precludes the conclusion that there is a causal relationship between glyphosate exposure and non-Hodgkin lymphoma, Dr. Kuzel’s mycosis fungoides latency opinion, although Dr. Kuzel may opine generally as to latency for cancers. Otherwise the motion is denied.
  1. Plaintiff’s Motion for Summary Adjudication: The motion was granted.
