James Cohen, center, carries his son Jason during a rally in support of the U.S. Supreme Court decision on the Defense of Marriage Act at the Miami-Dade Gay and Lesbian Chamber of Commerce in Miami Beach, Fla., Wednesday, June 26, 2013. The justices issued two 5-4 rulings in their final session of the term. One decision wiped away part of a federal anti-gay marriage law that has kept legally married same-sex couples from receiving tax, health and pension benefits. The other was a technical legal ruling that said nothing at all about same-sex marriage, but left in place a trial court's declaration that California's Proposition 8 is unconstitutional.

TALLAHASSEE, Fla. (AP) - The attorney general of Florida says in court documents that recognizing same sex marriages performed in other states would "impose significant public harm."
Eight gay couples and the American Civil Liberties Union have sued the state in federal court. The lawsuit argues Florida is discriminating against the couples by not recognizing same-sex marriages performed in states where they are legal.
Attorney General Pam Bondi has filed a response that asks a federal judge to throw out the lawsuit.
Bondi's office says the state has a legitimate interest in defining a marriage as between a man and woman because Florida's voters adopted an amendment in 2008 that banned same-sex marriages.
The filing also says same-sex marriage recognition would create significant problems for the state's pension and health insurance programs.
