A Manhattan federal judge on Wednesday certified three classes of plaintiffs who sued the maker of Kind nutrition bars for false advertising, alleging that the company had incorrectly labeled its products as “all natural” and “non-GMO.”

The ruling, from U.S. District Judge William H. Pauley III of the Southern District of New York, allowed plaintiffs in the multidistrict litigation who had purchased the popular bars in New York, California and Florida to proceed with class claims against Kind LLC, and rejected the company’s argument that different definitions of what the plaintiffs took “all natural to mean” blocked their bids for certification.
