All suits resolved  

Note: Under federal law, a three-judge federal trial court hears constitutional challenges to federal or state legislative districts or requests for preclearance, and these decisions are appealed directly to the U.S. Supreme Court. Federal appellate courts therefore tend to get involved only when there is no constitutional challenge or judicial preclearance request, or when only local districts are challenged.
