NEW ORLEANS (AP) — A judge in Louisiana has ruled that the state's ban on same-sex marriage is unconstitutional, in part because he says it violates equal protection rights.

KLFY-TV reported that Judge Edward Rubin ruled Monday that the ban violated the 14th Amendment and the constitutional requirement that states give "full faith and credit" to each other's laws.

His ruling came in same-sex adoption case of Angela Costanza and her partner, Chasity Brewer.

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

The state attorney general's office says they are appealing.
