(MCT) NEW YORK — A judge on Monday invalidated anti-obesity legislation that would have made New York the nation’s first city to restrict sales of super-sized sugary drinks, setting up a showdown with Mayor Michael R. Bloomberg, who called the last-minute ruling “completely wrong” and vowed to appeal.

Supreme Court Judge Milton Tingling’s 36-page decision came on the eve of the legislation’s planned implementation. It was a victory for a coalition of groups, ranging from labor unions to the restaurant industry, who had sued to block enforcement after the city’s Board of Health easily approved the law last September.
