To an increasing degree, Supreme Court justices have been explicitly invoking the alleged constraints of stare decisis, especially by way of criticizing justices thought to be ignoring those constraints. But this accelerating use of stare decisis as a rhetorical weapon is at odds with what the data show about the frequency with which stare decisis actually operates as a genuine constraint on Supreme Court decision-making. It is thus not surprising that justices who criticize other justices for ignoring stare decisis are justices who themselves rarely if ever subject their own first-order outcome preferences to the demands of stare decisis. In the final analysis, stare decisis, perhaps unfortunately, serves far more of a rhetorical function than a decision-guiding or decision-constraining one, at least recently, and at least in the Supreme Court.
