Alabama Chief Justice Roy Moore's outspoken opposition to gay marriage is a violation of judicial ethics, the Southern Poverty Law Center (SPLC) said Wednesday.

The SPLC filed a complaint against Moore to the Judicial Inquiry Commission of Alabama on January 28. The group filed a supplement on February 3.

In its initial complaint, the SPLC accused Moore of “encouraging lawlessness by attempting to assemble state officials and judges to oppose the federal court system” after a federal district court judge struck down Alabama's ban on gay marriage.

In its latest filing, the SPLC said Moore continues to “flout and violate” the state's code of judicial ethics following a ruling by the Supreme Court striking down gay marriage bans in all 50 states.

“The filing to the Judicial Inquiry Commission of Alabama alleges that Moore has committed new ethics violations by improperly commenting on pending or impending cases in numerous speeches and interviews; by suggesting that Supreme Court precedent need not be followed; and by announcing that he would recuse himself from cases rather than apply precedents with which he disagreed,” the group said in a written statement.

“If Chief Justice Moore wants to make political speeches or be an activist in opposition to same-sex marriage, he is free to do so, but he cannot simultaneously hold his current position on the Alabama Supreme Court,” said SPLC President Richard Cohen. “It's obviously unethical for him to urge defiance of a United States Supreme Court ruling. He needs to understand that he is a judge, not a preacher.”

In speaking out against marriage equality, Moore has claimed that such unions go against God, will lead to incest, polygamy and child abuse, and will “destroy” the United States.

The Judicial Inquiry Commission of Alabama is the same court that ousted Moore from the bench in 2003 for refusing to remove from public property a monument of the Ten Commandments which he had commissioned.
