Federal jurisdiction is based on "controversies between citizens of different States, and between a State: or citizens thereof, and foreign States, citizens, or subjects." Positions on the transfer of diversity jurisdiction range from keeping it intact to eliminating it completely. The basic reason for retaining diversity jurisdiction in courts has been to protect out-of-State litigants from bias. Another concern is the belief that the quality of justice is better in Federal courts because the judges are better qualified and there is less congestion and better rules of procedure. There are also those who believe that the present system encourages Federal and State systems to borrow from each other to the benefit of both systems. A major reason to transfer diversity cases to the State level is the increasing caseload on the Federal level. If these cases were given back to the States, a major problem would be how to distribute them among the States.
