Prof. Lee Petherbridge releases study of impact of legal scholarship on Supreme Court

A new study by Loyola Law School Professor Lee Petherbridge and Chicago-Kent College of Law Associate Professor David L. Schwartz details the impact of legal scholarship on the Supreme Court. The study, "An Empirical Assessment of the Supreme Court's Use of Legal Scholarship," is available for download on SSRN.

Abstract:

Derogating legal scholarship has become something of a sport for leading figures in the federal judiciary. Perhaps the chief antagonist in recent years has been none other than the Chief Justice of the U.S. Supreme Court, John G. Roberts Jr. His most recent salvo includes the claim that because law review articles are not of interest to the bench, he has trouble remembering the last law review article he read. This claim, and others by the Chief Justice, may represent the end of an uneasy détente concerning the topic of the utility of legal scholarship to the bench and bar. At a minimum, Justice Roberts's recent comments represent a vigorous invitation to a discussion, which this article accepts. To that discussion we contribute an empirical study that is based on an original and unprecedented body of data derived from every Supreme Court decision over the last sixty-one years. This article presents several surprising results and makes two major novel contributions. The first is evidence describing the amount and patterns of the Supreme Court's use of legal scholarship over the last sixty-one years. The second, and perhaps most striking contribution of this article, is empirical evidence on the nature and quality of the Court's use of scholarship. This article provides the first report, as far as we can determine, of evidence that the Supreme Court not only often uses legal scholarship, it also disproportionately uses scholarship when cases are either more important or more difficult to decide. It thus presents results strongly counterintuitive to claims that scholarship is useless or irrelevant to judges and practitioners. The article also discusses areas for future work.
