The new year is off to a strong start for Monsanto as the Bayer unit heads into its second trial over allegations that its Roundup and other glyphosate-based herbicides cause cancer. In a Jan. 3 ruling, U.S. District Judge Vince Chhabria rejected arguments by attorneys representing cancer victims and sided with Monsanto in deciding to block jurors from hearing a large portion of evidence that plaintiffs say shows efforts by Monsanto to manipulate and influence regulators in a first phase of the trial. In deciding to bifurcate the trial, Chhabria said that jurors will only hear such evidence if they first agree that Monsanto’s weed killer did significantly contribute to causing the plaintiff’s non-Hodgkin lymphoma (NHL).

“A significant portion of the plaintiffs’ case involves attacks on Monsanto for attempting to influence regulatory agencies and manipulate public opinion regarding glyphosate. These issues are relevant to punitive damages and some liability questions. But when it comes to whether glyphosate caused a plaintiff’s NHL, these issues are mostly a distraction, and a significant one at that,” the judge’s order states.

He did provide a caveat, writing, “if the plaintiffs have evidence that Monsanto manipulated the outcome of scientific studies, as opposed to agency decisions or public opinion regarding those studies, that evidence may well be admissible at the causation phase.”

Jury selection is set to begin Feb. 20 with the trial set to get underway on Feb. 25 in San Francisco. The case is Edwin Hardeman v. Monsanto.

Meanwhile, plaintiff Lee Johnson, who was the first cancer victim to take Monsanto to trial, winning a unanimous jury verdict against the company in August, has also won his request to the 1st District Court of Appeals for speedy handling of Monsanto’s appeal of that jury award. Monsanto opposed Johnson’s request for “calendar preference,” but the court granted the request on Dec. 27, giving Monsanto 60 days to file its opening brief.
