A special judge was named in Southaven Mayor Greg Davis' misdemeanor traffic case.
Judge Steve Ross from Tallahatchie County, which is near Grenada, Mississippi, will oversee the case.
A special judge was called in because all local justice court judges recused themselves.
Davis is charged with overtaking a school bus and illegal use of blue and red lights on his private vehicle in connection with a March 22 incident involving a stopped school bus in Southaven.
Davis pleaded not guilty.
