Civil marriage equality in effect at the state level since January 2015. (Same-sex couples may legally marry.)
1 case in the 11th Circuit Court of Appeals; 1 case in federal district court; 7 cases in state courts.
Unfortunately, proposed state legislation, SB 196 Families First, that would have provided most of the major state benefits of marriage to same-sex couples via Domestic Partnerships, died in the Judiciary Committee on 3 May 2013.
A constitutional ban against same-sex marriages and civil unions was in force from 2008 to early 2015, per Florida Amendment 2.
