Tracing the arc of Supreme Court oral argument durations reveals compelling insights into the institution’s evolution. At one time, lengthy orations stretching over days were the norm, as exemplified by Daniel Webster’s marathons in Gibbons v. Ogden and the multi-day exchanges in McCulloch v. Maryland. Yet, the modern high court operates in markedly different ways, as noted by legal scholars like Seth Waxman in his evaluation of how presentations have shifted over centuries.
A recent discussion by Adam Feldman over at Empirical SCOTUS illustrates how this transformation reflects broader judicial trends across seven decades. Total oral argument hours saw a decline starting in the late 20th century, reducing from over 140 hours per term during the Warren Court era to a humble 51.7 hours in the 2013-14 term—an almost 70% plunge. Recently, a slight resurgence to some 86.5 hours as of the 2024-25 term indicates partial recovery, albeit under functionally different conditions.
Despite overall reductions, average argument times per case bucked the trend, seeing a curious uptick. While historically shrinking from 54-57 minutes in earlier decades, recent terms witness longer engagements, averaging 92.4 minutes per case in the 2022-23 term. Adapting to fewer cases, the Court grants extended argument times to probe deeply into the issues at hand—most notably in high-profile cases like Students for Fair Admissions v. Harvard and Dobbs v. Jackson Women’s Health Organization, where extended deliberations were deemed necessary.
Conversely, some arguments close briskly, based on confessed errors or tightly technical queries, as evidenced in historical instances like Carella v. California with a mere 24 minutes argument time. Likewise, in the current term, Coney Island Auto Parts Unlimited, Inc. v. Burton was resolved within 35 minutes, demonstrating efficiency in simpler or more technical matters.
In most cases, the Supreme Court balances arguments in line with the complexity and consequence of individual cases; longer arguments align with intricate legal challenges. Notably, the structured approach introduced during the 2020 Covid pandemic has endured, influencing enlargements on average oral durations. As we move forward, anticipations suggest a continuation or even stabilization of longer times per case, particularly where significant issues demand extensive attention.
Historically lengthy orations may now belong to another era, but today’s Supreme Court strives to utilize argument time efficiently, sizing sessions according to necessity. This shift doesn’t undermine the significance of oral arguments; rather, it refines this legal ritual, underscoring its role in resolving only the most pressing questions before the nation’s highest court.
