Alabama Chief Justice Roy Moore filed a lawsuit against the state's judicial Inquiry Commission (JIC) in May after the oversight body announced that it would pursue ethics charges against him and suspended him from the bench.
Moore, who is represented by Liberty Counsel's Mat Staver, argues that the JIC has no legal authority over him.
"We are asking the federal court to strike down the automatic removal provision in the Alabama State Constitution and we are asking that Chief Justice Moore be immediately reinstated," Staver told the Associated Press.
The JIC said it levied the charges because Moore "knowingly ordered" the state's probate judges to disregard the U.S. Supreme Court's June 2015 marriage equality decision. Months after the ruling came down, Moore argued that the high court's action did not overturn Alabama's ban on same-sex marriage.
