Judge could decide today on whether to call for new Roundup trial

A San Francisco judge is slated to make a final decision today about whether to toss out part of a jury's $289 million award to a school groundskeeper who claimed Monsanto's Roundup weedkiller contributed to his cancer. Dewayne Johnson was one of hundreds of plaintiffs who have sued Monsanto over claims that Roundup — which contains the chemical glyphosate — could cause cancer and that the company didn't adequately warn consumers about that risk. But experts say the science on glyphosate and cancer risk is far from settled. Judge Suzanne Bolanos has suggested she may overturn the $250 million in punitive damages, cut down the remaining reward, and call for a new trial.
