There are dozens of sources where you can read about this on the internet. Without exception the ones I looked at were of the sort of axegrinding, hissy fitting people that make me distrust their facts.

I did however manage to find the actual opinion from the court is available.

The opinion can be read at http://www.2dca.org/opinions/Opinion_Pages/Opinion_Page_2003...

The paragraph that begins at the bottom of page 3 and finishes on the top of page 4 is the meat.

While WTVT has raised a number of challenges to the judgment obtained by Akre, we need not address each challenge because we find as a threshold matter that Akre failed to state a claim under the whistle-blower's statute. The portion of the whistle-blower's statute pertinent to this appeal prohibits retaliation against employees who have “[d]isclosed, or threatened to disclose,” employer conduct that “is in violation of” a law, rule, or regulation. § 448.102(1)(3). The statute defines a “law, rule or regulation” as “includ[ing] any statute or . . . any rule or regulation adopted pursuant to any federal, state, or local statute or ordinance applicable to the employer and pertaining to the business.” § 448.101(4), Fla. Stat. (1997). We agree with WTVT that the FCC’s policy against the intentional falsification of the news – which the FCC has called its “news distortion policy” – does not qualify as the required “law, rule, or regulation” under section 448.102.

The case was: NEW WORLD COMMUNICATIONS OF TAMPA, INC., d/b/a WTVT-TV, Appellant, v. JANE AKRE, Appellee.

The source (that I found) is LexisNexis' compilation: "FL Courts of Appeal Cases from 1957"
