Although scholars have established that oral arguments play a role in Supreme Court decision making, a fundamental question remains: can oral arguments change justices' votes? Using data on the positions taken by Justices Blackmun and Powell prior to oral arguments, the authors seek to answer this question while implicitly addressing another: how effectively can attorneys persuade the Court during arguments dominated by justices attempting to persuade each other? The authors find that in a significant minority of cases, justices are persuaded to switch their vote as a result of oral argument and that high-quality attorneys play a central role in that persuasion.
