A California jury that awarded a $289 million Roundup verdict disregarded science and the consensus of federal regulators and fell victim to “emotional manipulation,” according to the state’s doctors, farmers and biotech firm Genentech Inc., in amicus briefs filed in Monsanto’s appeal.

In three separate briefs, the California Farm Bureau Federation, the Civil Justice Association of California and Genentech sought to reverse the 2018 verdict against Monsanto, now owned by Bayer.
