Fresh off a fifth-in-a-row trial victory, Monsanto owner Bayer AG is rejecting a proposed “global resolution plan” put forward by plaintiffs’ lawyers as a last chance to try to settle tens of thousands of pending Roundup cancer claims before a wave of new trials get underway, newly filed court documents show.

The company stance comes at a pivotal point in the ongoing nationwide litigation involving plaintiffs who allege they developed non-Hodgkin lymphoma (NHL) from exposure to Monsanto’s glyphosate-based weed killers, such as Roundup.

The group of law firms leading the cases in what is called “multidistrict litigation (MDL)” asked US District Court Judge Vince Chhabria to approve a plan that would set a 60-day window in which both sides would try to forge a final global settlement that would cover the claims of roughly 30,000 plaintiffs.

If no settlement can be reached, the plaintiffs’ firms want the judge to start the process of dissolving the MDL and clearing waves of cases to go to trial in the states where they originated.
