Justice Brett Kavanaugh has emerged as the Supreme Court's most prolific concurring opinion writer, a shift that reshapes how the Roberts Court communicates its constitutional reasoning.
Data from SCOTUSblog shows Kavanaugh penned more separate concurrences across the 2023 and 2024 terms than any other justice currently serving. His approach departs sharply from Chief Justice John Roberts' institutional preference for majority opinions that bind lower courts uniformly. Kavanaugh's concurrences—opinions that agree with the outcome but offer different legal rationales—create fragmented precedent.
The practical consequence runs deep. When justices write separately rather than join a single majority opinion, lower courts struggle to discern binding holdings. Federal and state judges must navigate multiple constitutional theories to understand what the Supreme Court actually requires. This increases litigation costs and unpredictability in appellate practice.
Kavanaugh's concurring strategy reflects tensions within the current conservative majority. His opinions often narrow holdings or suggest alternative grounds for decisions, suggesting he seeks common ground with Chief Justice Roberts and Justice Amy Coney Barrett. On divisive issues, these concurrences function as a brake on broader constitutional rulings that five other justices might prefer.
The pattern appears especially pronounced in cases touching religious liberty, criminal procedure, and administrative law. Kavanaugh's separate opinions stake out middle positions, rejecting both sweeping conservative positions and liberal dissents.
Court observers note this creates a jurisprudential puzzle. Kavanaugh's concurrences technically lack stare decisis power beyond their holding. Subsequent panels cannot rely on his rationale as binding precedent. Yet his opinions carry weight as signals of where he might move the Court in future cases.
The Roberts Court has always permitted concurrences, but their frequency and strategic deployment by Kavanaugh marks a departure. Some scholars argue this
