A federal judge has slashed an $80 million Roundup verdict to about $25.3 million after finding that Monsanto’s conduct, while “reprehensible,” did not justify a “constitutionally impermissible” punitive damages award.

U.S. District Judge Vince Chhabria of the Northern District of California, who refused to overturn the verdict Friday, found that Monsanto Co.’s conduct was sufficient to warrant punitive damages of $20 million—a ratio of four times the compensatory damages.
