The U.S. Supreme Court on Wednesday said Virginia need not restore 1,600 suspected noncitizens to its voter rolls following a state-ordered, near election-eve purge that the Department of Justice alleges was riddled with mistakes.

Last week, a federal district court ordered Virginia to reinstate the names of the stricken registered voters amid a legal challenge by the DOJ and immigrant rights groups. The U.S. Court of Appeals for the Fourth Circuit on Sunday kept the injunction in place.
