TALLAHASSEE, Fla. – A legal challenge to a 2018 constitutional amendment that will end greyhound racing in Florida has gone to a federal appeals court. As is common, the notice does not detail arguments the plaintiffs will make at the 11th U.S. The lawsuit argues that the voter-approved ballot measure violates a series of rights under the U.S. Constitution, including equal-protection rights because horse racing will be allowed to continue at pari-mutuel facilities while dog racing will be blocked. Walker issued a 55-page ruling in April that dismissed a version of the lawsuit but allowed the plaintiffs to amend and refile it. But in his ruling last month, Walker quickly disposed of the amended version, saying that the plaintiffs “lack standing” to sue Moody over the ban.
