From another article:
It is now up to Attorney General Tom Horne to decide whether he will appeal or comply and instruct county clerks to begin issuing licenses to same-sex couples. After conceding in a court filing Thursday that the ruling from the U.S. Court of Appeals for the 9th Circuit would apply to Arizona, he’s widely expected to do the latter. It’s now likely just a question of when.
Horne is expected to have a news conference Monday to announce his decision. His spokesperson, Stephanie Grisham, said they are “ethically obligated to consult with their clients” about their next steps first.
UPDATE: AG Tom Horne says the state will not appeal. Marriages will begin immediately.
