"We firmly believe the plaintiffs' claims are without merit and will ultimately be rejected," Raivish said in a statement.
In 2010, another New York judge denied Coca-Cola's attempts to have the lawsuit dismissed on technical grounds. At that time, Judge John Gleeson said Vitaminwater's use of the word "healthy" violates Food and Drug Administration labeling rules. In a 55-page opinion, Gleeson also took issue with Vitaminwater's name, which fails to identify sugar as a key ingredient in the drink, though it is listed in nutrition information on the bottles.
The Washington-based Center for Science in the Public Interest hailed the opinion as a major victory.
"Today's decision puts this case on a glide path toward a jury trial where Coca-Cola will have to defend under penalty of perjury the deceptive claims it has made and continues to make in connection with Vitaminwater," said Steve Gardner, lawyer for the Center for Science in the Public Interest.
