The Institutionalization of the U.S. Supreme Court

In pursuing their goals, members of the U.S. Supreme Court areaffected by their institutional setting. How has that institutionalenvironment changed over time and what have been the politicalconsequences of those changes? Despite considerable analysisof the institutional dynamics of legislatures and executives,political scientists have been slow to bring time series techniquesto the study of the Supreme Court, and as a result much lessis known about its evolutionary path. Measuring a variety oforganizational characteristics, I construct an index of theinstitutionalization of the Supreme Court from 1790 to 1996.This indicator suggests that the integration of the Court intothe system of federal policy making has better enabled the justicesto satisfy their objectives. To demonstrate this empirically,I test a series of error correction models of judicial influence,each of which confirms that the nature of the Supreme Court'scharacter has had considerable implications for the scope ofthe justices' legal and political impact. These results underscorethe need for judicial scholars to examine the Court's policymaking in longitudinal perspective.
