Supreme Court Justice Clarence Thomas recently raised eyebrows by questioning the principle of stare decisis—the doctrine that courts should generally follow precedent. At face value, his comments were almost a “DUH” moment. After all, the very reason appellate courts exist is to reconsider prior decisions. If every ruling were beyond review, there would be no need for a Supreme Court.
The Train Metaphor
Thomas’s remarks, delivered in a lecture, were couched in a metaphor: blindly following precedent, he said, is like passengers on a train who never look to see who’s driving. Even if the train were run by an “orangutan,” they would keep moving forward simply because “it’s a train.” His point was that precedent should not be treated as sacred, but rather weighed against law, tradition, and logic.
Why the Outrage?
Taken in isolation, this is hardly controversial. Courts have always overturned precedent when it was deemed wrong—Brown v. Board of Education famously discarded Plessy v. Ferguson’s “separate but equal” doctrine. Legal stability matters, but the Constitution was not designed to enshrine every past ruling forever.
The controversy arises because of Thomas himself. His record shows a willingness to discard precedent far more aggressively than his colleagues. He has joined or led decisions undoing decades of settled law on abortion, affirmative action, and voting rights. His recent suggestions that rulings on same-sex marriage or contraception might also be reconsidered amplify fears that no precedent is safe under his philosophy.
Timing and Trust
His blunt dismissal of stare decisis also comes at a time when public confidence in the Court is near historic lows. For critics, it sounds less like a call for careful legal review and more like a declaration that the Court can sweep aside whatever it dislikes.
From “DUH” to Debate
In short, Thomas stated something almost self-evident: precedents can be overturned when they are wrong. The controversy arises not from the idea itself, but from his application of it. His “DUH” moment resonates differently when voiced by a justice who has already upended multiple pillars of American law. That tension—between principle and practice—is what makes a banal truth into front-page controversy.
