The post of presiding judge of the state's Supreme Court became vacant last November after Moore was removed from office for refusing to obey a federal order demanding he remove a stone monument to the origins of U.S. law that he had installed in the rotunda of the state judicial building.
The monument featured the biblical Ten Commandments in a prominent position, leading critics to charge it violated the constitutional prohibition on the establishment of a state religion, a position ultimately upheld by the court.
On April 30, a special Alabama Supreme Court voted unanimously to endorse Moore's removal from office.
Nabers, 63, has a law degree from Yale University and had been a practicing attorney in Birmingham, Ala., before entering the insurance business. As the state's finance director, Nabers had been tasked with overseeing state spending, borrowing, budgeting and purchasing.
