NEW ORLEANS (AP) — A federal judge gives Louisiana 15 days to add the names of both fathers to the birth certificate of a boy born in Shreveport and adopted by a gay couple from out-of-state. Louisiana Attorney General Buddy Caldwell says he will appeal Wednesday’s ruling by U.S. District Judge Jay Zainey.   Caldwell says the judge significantly misinterpreted Louisiana law, and is forcing the state to adopt another state’s laws.  The judge refused a request for a full trial.
