WASHINGTON – Justice Clarence Thomas has reached a significant milestone, becoming the second-longest serving justice in the history of the United States Supreme Court. This achievement comes at a pivotal time when his influence within the conservative legal movement appears to be stronger than ever.
Over the past decade, once considered an outlier, Thomas has emerged as a key architect of landmark decisions on critical issues such as abortion rights, voting access, and Second Amendment rights. His tenure, which began in 1991, has evolved dramatically, especially following the appointment of three conservative justices by former President Donald Trump.
Currently, the only justice with a longer tenure is William O. Douglas, who served until 1980. If Thomas remains on the bench until 2028, he will surpass Douglas, and there are no indications he plans to retire soon. “I think he’s more energized and excited now than when I first met him,” remarked John Yoo, a law professor and former Thomas clerk, reflecting on Thomas’s sustained vigor and commitment to his judicial role.
Thomas’s confirmation was marred by contentious hearings, including allegations of sexual harassment. Nevertheless, he has transformed from a relatively silent figure during oral arguments to a prominent voice, often initiating discussions and contributing to pivotal rulings that expand Second Amendment rights. His seniority grants him significant power within the court, allowing him to influence opinions even if Chief Justice John Roberts is not part of the majority.
As the most senior member of a conservative supermajority, Thomas has played a crucial role in reshaping the judicial landscape, contributing to the overturning of established precedents on abortion, affirmative action, and voting rights. Stanford University law professor Pamela Karlan noted, “The court has radically moved in his direction over the course of his time on the court,” indicating the profound impact of his jurisprudential philosophy.
Beyond the bench, Thomas maintains a vast network of former clerks who have taken influential positions in the Trump administration and the federal judiciary, further extending his legacy. Sarah Konsky, director of the Supreme Court and Appellate Clinic at the University of Chicago Law School, emphasized that “significant influence lives on through their clerks,” highlighting the enduring nature of Thomas’s mentorship.
Despite facing scrutiny over undisclosed luxury trips and the political activities of his wife, Thomas remains a formidable presence on the court. His views align with a conservative vision of limited government, which he articulated during a recent speech, earning a standing ovation from attendees.
At 77 years old, Thomas’s tenure now exceeds 34 years, placing him ahead of Justice Stephen J. Field, who served from the Civil War era until 1897. Thomas’s journey has not been without hurdles, including past allegations of sexual harassment that nearly derailed his nomination by President George H.W. Bush.
Recent years have seen Thomas authoring some of the most significant opinions of his career, particularly a 2022 ruling affirming the right to carry firearms in public. While his jurisprudence has remained consistent, legal scholars like Scott Gerber observe that he has transitioned from a justice often known for solo dissents to one who writes majority opinions that shape the court’s direction.
