Former Florida Governor Charlie Crist has filed an amicus brief in support of plaintiffs challenging Florida's ban on gay marriage.

The 57-year-old Crist has a complicated relationship with the LGBT community. In 2006, he signed a petition to put Florida's constitutional amendment limiting marriage to heterosexual couples on the ballot. Voters approved the ban two years later.

Since leaving the Republican Party – with a pit stop as an independent – Crist has reversed course, apologizing for his support of the ban and stating that chief among his reasons for leaving the GOP was its opposition to gay rights.

He is currently campaigning for his old job, as a Democrat.

“In just the last six years, our society has evolved and moved past the prejudices rooted in our past,” Crist said in a statement. “Further, science has uniformly reached the conclusion that heterosexual marriages are just as valued and revered as they have ever been; and children raised by gay and lesbian parents fare just as well as kids raised in straight families.”

“Thus, with the arc of history now, in fact, bending toward justice, this issue of marriage equality will almost certainly not even be an issue for the children and grandchildren of this State. But it is still the duty of those in the present to recognize that the legitimacy of government depends upon its willingness to fairly, transparently, and equitably administer the law. That goal is frustrated by denying an entire class of citizens equality in the institution of marriage simply because of who they are and whom they love.”

Circuit Court Judge Sarah Zabel will hear arguments in the case, Pareto v. Ruvin, on July 2 in Miami.
