Alabama Chief Justice Roy Moore stood firm Thursday in his position that the state's probate judges should not issue marriage licenses to gay couples, a stance he insisted is not in defiance of the U.S. Supreme Court ruling last summer that effectively legalized gay marriage nationwide.

Moore's remarks in an interview with The Associated Press came after two U.S. prosecutors issued a statement saying the probate judges need to obey the nation's highest court, not the state's highest justice.

Some of the judges who stopped issuing licenses Wednesday following Moore's administrative order resumed the service Thursday after consulting with county attorneys.

In his interview with the AP, Moore reiterated remarks first laid out in his order: that the Alabama Supreme Court has not lifted a March 3 order against issuing licenses to gay couples.

He said it's up to the state court to decide what to do with that order following the U.S. Supreme Court's decision.

"Probate judges should be following the orders of the Alabama Supreme Court, the highest state authority. If that state authority does find that (the U.S. Supreme Court decision) does have an effect on their order, they will remove the injunction. If they do not, I guess the injunction will continue," Moore said.

Moore said he sent his order because probate judges were confused about what to do.

Two federal prosecutors in Alabama, however, said Wednesday night that there should be no confusion, because the U.S. Supreme Court ruling trumps whatever the state court has to say on gay marriage.

U.S. Attorneys Joyce White Vance of the Northern District of Alabama and Kenyen Brown of the Southern District of Alabama issued a statement saying they had "grave concerns" about Moore's administrative order.

Some probate judges who had stopped issuing all marriage licenses in response to Moore's order Wednesday said Thursday they had resumed the service after consulting with attorneys.

"We're back to our normal issuance just like we had been before yesterday," said Lawrence County Probate Judge Michael Praytor, adding that license operations had only been suspended for about three hours after the order was issued Wednesday afternoon.

Praytor said the Association of County Commissions of Alabama, which provides his office's insurance, emailed him to give guidance on how to resolve the issue. He said the ACCA cited opinions from federal officials and a representative of the University of Alabama's school of law in the guidance his office was given.

"It was basically the same thing that they had before when the (U.S. Supreme Court) ruling came down," Praytor said.

Officials in Madison County said they also had resumed issuing licenses. Mobile County said licensing operations were still suspended.

Moore is a historically controversial figure in Alabama who was once removed from judicial office for refusing to follow a federal judge's order to remove a Ten Commandment's monument from the state judicial building. He also has been an outspoken critic of gay marriage, once predicting in a campaign speech that it would be the ultimate destruction of the country. He declined to say during Thursday's interview, however, what the Alabama Supreme Court should decide when reviewing the U.S. court's ruling.

Civil rights organizations and gay-marriage advocates have blasted Moore's latest order, saying that it is sure to be challenged and defeated in court.

In an interview Wednesday, University of Alabama School of Law Professor Ronald Krotoszynski said Moore's suggestion to probate judges to refuse to issue marriage licenses "constitutes an exercise in futility."

"At best, it sows chaos and confusion," he said. "At worst, it forces couples to bring federal court litigation in order to exercise a clearly established federal constitutional right."

Southern Poverty Law Center President Richard Cohen did not mince words when asked his opinion Thursday.

"Chief Justice Roy Moore is once again demonstrating that he is unfit to hold office," Cohen said.
