At the age of 46, DeWayne Johnson is not ready to die. But with cancer spread through most of his body, doctors say he probably has just months to live. Now Johnson, a husband and father of three in California, hopes to survive long enough to make Monsanto take the blame for his fate. Johnson will become the first person to take the global seed and chemical company to trial on allegations that it has spent decades hiding the cancer-causing dangers of its popular Roundup herbicide products - and his case has just received a major boost. Last week Judge Curtis Karnow issued an order clearing the way for jurors to consider not just scientific evidence related to what caused Johnson's cancer, but allegations that Monsanto suppressed evidence of the risks of its weed killing products. "The internal correspondence noted by Johnson could support a jury finding that Monsanto has long been aware of the risk that its glyphosate-based herbicides are carcinogenic ... but has continuously sought to influence the scientific literature to prevent its internal concerns from reaching the public sphere and to bolster its defenses in products liability actions," Karnow wrote. Johnson's case ... is at the forefront of a legal fight against Monsanto. Some 4,000 plaintiffs have sued Monsanto alleging exposure to Roundup caused them, or their loved ones, to develop non-Hodgkin lymphoma (NHL).
