WASHINGTON (CN) – Explaining why he advanced a labeling challenge to the weedkiller Roundup, a federal judge said Monday that there is enough evidence at this stage to support the claim that Monsanto misleads consumers.

U.S. District Judge Timothy Kelly, a Trump appointee, issued his opinion about a month after promising to explain himself on March 31 when he rejected Monsanto’s motion to dismiss.

The groups Beyond Pesticides and the Organic Consumers Association brought the underlying suit in April 2017, saying Roundup labels falsely claim that glyphosate, a key ingredient,- “targets an enzyme found in plants but not in people or pets.”

Insisting that the enzyme does in fact exist in the animal gut bacteria, and that Monsanto knows that, the groups say Monsanto’s deceptive labeling conceals glyphosate’s potential health effects from consumers.

“The court concludes that Plaintiffs have adequately pleaded a claim that the statement at issue was false or misleading,” Kelly wrote Monday.
