Suspended Alabama Chief Justice Roy Moore is suing the state agency that filed ethics charges against him.

Attorneys for Moore filed a federal lawsuit Friday against the Alabama Judicial Inquiry Commission. The suit asks a court to order Moore's immediate reinstatement as head of Alabama's court system.

The suit says a law that led to Moore's automatic suspension when charges were filed against him earlier this month is unconstitutional. The lawsuit also cites news reports and reporters' questions about possible charges against Moore in claiming the commission violated confidentiality provisions.

An attorney for the commission didn't immediately return an email message seeking comment.

The commission filed a complaint accusing Moore of willfully failing to respect the authority of federal court decisions that cleared the way for gay marriage.
