"Leapfrog’s change in methodology has no scientific basis, unfairly penalizes non-participating hospitals, and misrepresents hospital safety. For the reasons that follow, I find that Leapfrog’s approach constitutes an unfair and deceptive business practice in violation of the Florida Deceptive and Unfair Trade Practices Act. Fla. Stat. § 501.201 et seq.” Donald M. Middlebrooks, United States District Judge
