Scholars have long been interested in judicial impact—the ability of courts to meaningfully alter policy or politics—because judicial decisions shape law, have the potential to affect many people, and may even implicate democracy in a fundamental sense. Classic studies in this tradition concern the degree to which actors outside the court comply with judicial decrees, such as whether or not (or to what extent) schools desegregated in the wake of Brown v. Board of Education. However, scholars working in a variety of other traditions have likewise examined the impact of judicial decisions, though they have not always used those terms. For example, advocates of interbranch analysis have situated courts within broader ongoing policy processes, and in so doing have documented repeated instances in which policy outcomes were altered by the actions of lawyers and judges. Likewise, students of legal mobilization have documented the sometimes constitutive effects of legal ideas on a wide range of political identities, attitudes, and behaviors. In short, the concept of impact includes a variety of ways in which courts influence politics, and the field of judicial impact studies will continue to benefit from a vital diversity of methods of inquiry, subjects of analysis, and conceptions of law.
