Integrated process models that combine both legal and extralegal variables provide a more accurate specification of the judicial decision making process and capture the complexity of the factors that shape judicial behavior. Judicial decision making theories borrow heavily from U.S. Supreme Court research, however, such theories may not automatically be applicable to the lower federal bench. The author uses vote dilution cases originating in the federal district courts from the years 1965 to 1993 to examine what motivates the behavior of district and circuit court judges. The author uses an integrated process model to assess what factors are important to the adjudication process and if there are significant differences between federal district and appellate court judges in decision making.
