Decoding the Supreme Court’s Oral Arguments: Predicting Opinion Authorship and Judicial Insights

The process of understanding Supreme Court decisions extends beyond just reading the final opinions. The intricate dance of oral arguments provides crucial insights into the eventual authorship and substance of the Court’s opinions. Recent analysis in Empirical SCOTUS, a series by Adam Feldman, sheds light on how the dynamics of oral arguments can signal the trajectory of a case and the justice likely to pen the majority opinion.

A noteworthy finding is the significance of early engagement in arguments. While it might be assumed that sheer volume of speech indicates a justice’s commitment to writing the opinion, Feldman argues that it is the early, incisive engagement in the first 25 exchanges that is the better predictor of authorship. This early focus allows a justice to frame the case’s doctrinal structure, signalling an ownership over the legal problem at hand.

In contrast, when justices author separate opinions, such as concurrences or dissents, their engagement during oral arguments takes on a different form. Here, the persistence and distinctiveness of their language throughout the argument become predictive of authorship. This difference underscores a separate author’s focus on staking out individual positions rather than seeking consensus within the Court.

The analysis highlights distinctive styles among the justices. For example, Justice Neil Gorsuch’s questioning in Case v. Montana mirrors his later concurrence, reflecting the common-law necessity privilege—a concept that guided his thought process from argument to opinion.

Overall, Feldman’s analysis suggests oral arguments are more than performative exercises. They are an essential part of the judicial decision-making process, offering early insight into which justice may take the lead in shaping the Court’s voice on a given matter.
