미국 연방대법원의 정치화와 스윙 보수 대법관의 재등장 가능성

In recent years, the United States Supreme Court—though constitutionally vested with the ultimate authority to interpret the Constitution—has faced increasing criticism for rendering decisions not on the basis of neutral legal reasoning, but rather along political and ideological lines. Particularly in high-profile cases involving affirmative action, gun regulation, and abortion rights, the Court’s rulings have deepened social polarization and raised suspicions that judicial outcomes are driven more by political considerations than by legal principles. Such perceptions have intensified since President Trump appointed three conservative justices, thereby consolidating a 6–3 conservative majority. As a result, ideologically transcendent decisions have become increasingly rare. In contrast, during earlier periods, “swing conservatives” such as Justices O’Connor and Kennedy played a pivotal role in mitigating ideological rigidity, maintaining institutional legitimacy through judicial restraint and respect for precedent. Since Chief Justice John Roberts assumed leadership, however, ideological polarization within the Court has deepened, and compromise- oriented rulings have become uncommon. Nevertheless, conservative justices John Roberts, Brett Kavanaugh, and Amy Coney Barrett have exhibited a form of judicial restraint grounded in institutional legitimacy and respect to precedent, revealing the potential emergence of a new type of swing conservative justice. Their approach does not amount to mere ideological centrism. Rather than pursuing political neutrality for its own sake, they have emphasized legal legitimacy and have occasionally sided with the liberal bloc on specific issues, thereby promoting institutional stability. Although they share roots in conservative interpretive traditions such as originalism and traditionalism, they have at times distinguished themselves from their more ideologically rigid colleagues by adopting gradualist and pragmatic reasoning. This study analyzes the evolving role of the so-called “swing conservative justices”—Roberts, Kavanaugh, and Barrett—amid the recent intensification of political polarization within the U.S. Supreme Court. While maintaining a conservative interpretive framework, these justices have at times adopted conciliatory positions with liberal justices, thereby demonstrating judicial restraint aimed at preserving the Court’s institutional legitimacy and adherence to stare decisis. Focusing on major Supreme Court cases, this study examines how their pragmatic approaches, distinct from the traditional conservative majority, seek to promote doctrinal consistency and transparency in constitutional interpretation. The analysis suggests that even within a politicized judicial environment, the principles of interpretive moderation and respect for precedent remain essential for the Supreme Court to function as a sustaining institution of democratic constitutional order.
