U.S. District Judge David G. Campbell disqualified Sigal Chattah from supervising four criminal prosecutions, siding with defense lawyers who argued that her authority expired in July and she is serving unlawfully. Campbell ordered government attorneys on the cases to tell the court within seven days that Chattah is not directing their work. He did not dismiss the indictments, however.
