The Florida Supreme Court waded into a constitutional fight about a higher state tax rate for satellite-television companies than for their cable TV competitors.

The Florida Department of Revenue and a cable industry group asked the justices to overturn an appeals court ruling last year that sided with satellite companies DirecTV and Dish Network. In a 2-1 decision, a panel of the First District Court of Appeal found that the differing tax rates were discriminatory and violated the Commerce Clause of the U.S. Constitution.
