When the Supreme Court takes action, it establishes national policy within an issue area. A traditional, legal view holds that the decisions of the Court settle questions of law and thereby close the door on future litigation, reducing the need for future attention to that issue. Alternatively, an emerging interest group perspective suggests the Court, in deciding cases, provides signals that encourage additional attention to particular issues. I examine these competing perspectives of what happens in the federal courts after Supreme Court decisions. My results indicate that while Supreme Court decisions generally settle areas of law in terms of overall litigation rates, they also introduce new information that leads to increases in the attention of judges and interest groups to those particular issues.
