For the counties that comprise the 4th Judicial Circuit, there will be no policy change Jan. 6. Duval County Clerk of Court Ronnie Fussell was not available for comment, but his office issued a statement saying it would not issue same-sex marriage licenses “until a binding order is issued by a court of proper jurisdiction.” Justin Horan, general counsel for the Clay County clerk of court, said the office will abide by the position endorsed by the state association. He said it will be “business as usual” on Jan. 6. The Nassau County clerk’s office also will be following the advice from the association, with no change in policy until a binding order is issued from a proper jurisdiction or Florida amends its constitution, said spokeswoman Liz Rodriguez. “It’s our responsibility to follow the law. We will not be issuing licenses for same-sex couples,” she said.
Florida’s 67 counties are divided into 20 judicial circuits, some of which comprise up to six counties each.
