NEW ORLEANS (AP) — Louisiana's  attorney general is asking the state Supreme Court to overturn a decision by a Lafayette Parish judge who declared Louisiana's  ban on same-sex marriage unconstitutional.

Attorney General Buddy Caldwell's Office filed the appeal Friday.

Judge Edward Rubin's ruling, handed down Monday in the same-sex adoption case of Angela Costanza and her partner, Chasity Brewer, affects only the 15th Judicial District, which also includes Acadia and Vermilion parishes.

Rubin says Constanza may adopt her partner's son and be listed as a parent on his birth certificate. The couple's lawsuit say the state should recognize their marriage, which took place in California.

The decision has been suspended pending the state's appeal and will have no immediate impact.

Caldwell's office is asking the state high court to rule quickly.
