Jury Awards


against Monsanto

Sonia Chopra of Chopra Koonan is proud to have been part of the plaintiff's trial team on the landmark case of Johnson v. Monsanto. On August 10, 2018 a San Francisco jury returned a unanimous verdict finding that Monsanto’s Roundup weed killer caused Mr. Johnson’s terminal cancer. The jury awarded $39.2 million in compensatory damages and $250 million in punitive damages against Monsanto for failing to warn consumers that Roundup causes cancer. This case represents the first of thousands of pending cases involving Roundup.
