ORLANDO, Fla. (AP) - Orlando's city council has voted to support overturning Florida's ban on same-sex marriage.

City council members approved Mayor Buddy Dyer's proposal to file a friend of the court brief in a lawsuit set for a hearing early next month in Miami.

The lawsuit is challenging the state's ban on same-sex marriage, claiming it violates the U.S. Constitution.

Orlando is joining with the City of Miami Beach in filing the friend of the court brief.

Orlando has a domestic partnership registry, and the same-sex partners of city workers are eligible for health insurance from the city.
