The concept of a “unitary judicial power” in the U.S. Supreme Court remains an underexplored area in constitutional law, particularly compared to the “unitary executive” theory that has gained attention over the years. A recent article on SCOTUSblog delves into this contentious issue, asking whether the singular nature of the Supreme Court as described in Article III of the Constitution grants it a robust, even unreviewable authority similar to the executive branch’s power derived from Article II.
The case of Hunter v. United States, currently before the Supreme Court, serves as a backdrop for exploring this idea. At issue is whether the Supreme Court has the authority to recognize and enforce exceptions to standard appeal waivers in federal criminal plea agreements. This touches upon the broader question of where the court derives its supervisory power over lower courts, especially in the context of plea agreements that have become common practice as noted in DOJ policy.
Legal scholars and judges have extensively debated the unitary executive theory, but less so the potential for a “unitary judiciary.” Article III states the judicial power shall be vested in “one Supreme Court,” suggesting a singular, comprehensive authority akin to that granted to “a President” in Article II. Some argue this implies the Supreme Court has an inherent power that does not require legislative approval, much like the executive power’s interpretation in the seminal case of Marbury v. Madison.
The implications of a robust unitary judicial power could be significant, potentially challenging congressional statutes that dictate the Supreme Court’s procedures and domain. The court’s inherent “supervisory authority” over federal courts has traditionally been accepted, but the legal and theoretical underpinnings of this power are not fully developed. Justices Elena Kagan and Amy Coney Barrett have both touched on the subject, indicating a need to balance these powers with constitutional intentions and historical practices.
While the notion of a unitary judicial power in the Supreme Court may be nascent, its exploration is becoming increasingly relevant as judicial, executive, and legislative powers continue to be dissected and defined. Legal academia and judicial decisions, notably the forthcoming ruling in Hunter, will play crucial roles in shaping the understanding and application of this constitutional theory.
