The Life of the Law: Judicial Politics and Legal Change

To what extent is legal change influenced by judicial politics? This question, as initially posed by legal realists, provided the stimulus for much of the early study of the judicial process Although judicial scholars have since explored the impact of judicial policy views, the litigation environment, and the political environment, no systematic analysis of the impact of these factors on legal change has been undertaken. I develop a measure of legal change and use it to test the impact of judicial politics by examining search and seizure cases decided by the Supreme Court between 1962 and 1989 Using a multinomial logit model, I find that several aspects of the judicial process, particularly the Court's political composition, legal constraints, litigant resources, attorney experience, amicus support, and presidential preferences, affect the direction of legal change.
