Institutions, Interests, and Judicial Outcomes: The Politics of Federal Diversity Jurisdiction

Since 1789, diversity of citizenship jurisdiction has been a staple of the American judicial system. After presenting a general theory of jurisdictional change and reviewing diversity jurisdiction's development, the author undertakes a quantitative analysis of congressional activity vis-à-vis diversity jurisdiction. That analysis provides evidence that both administrative concerns and attention to federal judicial outcomes have impacted legislative decisions concerning the scope of diversity jurisdiction. These findings also suggest that members of Congress are selective in dealing with the jurisdiction of federal courts and that approaches to jurisdictional oversight vary in response to the salience of the legal issues at hand.
