In a rare win for Monsanto, a Los Angeles jury found that its Roundup pesticide was not a “substantial factor” in causing a 10-year-old to suffer from an aggressive form of cancer called Burkitt’s lymphoma.

Tuesday’s verdict comes in a bifurcated trial in which jurors had to decide causation in the first phase. Had they sided with the plaintiff, Destiny Clark, the mother of Ezra Clark, the trial would have continued into a second phase on liability and damages.
