Clarence Thomas Poised to Break Supreme Court Tenure Record by 2028

Clarence Thomas Nears Historic Supreme Court Tenure Milestone

Justice Clarence Thomas has officially become the second-longest serving justice in the history of the U.S. Supreme Court. If he remains on the bench through 2028, he will surpass William O. Douglas, a Franklin D. Roosevelt appointee, to claim the title of the longest-serving justice in SCOTUS history.

Thomas' tenure has already left an indelible mark on the Court, with his long-held legal views shaping some of the most consequential decisions of recent years. "In one big case after another, from the expansion of gun rights to the elimination of the constitutional right to abortion, Thomas' long-held views either commanded or inspired the majority of the Court."

Key Rulings Influenced by Thomas

Thomas' impact was particularly evident during the Supreme Court's 2021–2022 term, which included landmark cases such as:

• New York State Rifle and Pistol Association v. Bruen (2022) – Expanded gun rights under the Second Amendment.
• Dobbs v. Jackson Women's Health Organization (2022) – Overturned Roe v. Wade, eliminating the constitutional right to abortion.

Mixed Outcomes in Recent Terms

The 2025–2026 term has seen a more mixed reception of Thomas' jurisprudence. While his longstanding opposition to a broad interpretation of the Voting Rights Act was reflected in Louisiana v. Callais, his advocacy for expansive executive power was rejected in Learning Resources v. Trump. Thomas responded with a strongly worded dissent, criticizing the majority's stance.

As of this writing, 11 major cases remain to be decided in the current term, leaving the full extent of Thomas' influence on these rulings yet to be determined.

Parallels Between Thomas and Stephen Field

Currently sitting in the third-longest serving spot is Stephen Field, an appointee of President Abraham Lincoln. The careers of Thomas and Field share striking similarities, particularly in their early years as dissenting justices whose legal philosophies eventually gained acceptance.

Field, like Thomas, spent much of his career writing dissents that were initially ignored but later embraced by the Court. His 1873 dissent in The Slaughter-House Cases was later adopted by the Supreme Court in 1897 and further reinforced in the landmark 1905 case Lochner v. New York, which had far-reaching implications for economic regulation and individual rights.

Field's career demonstrates a critical truth about the Supreme Court: "a future Supreme Court always can, and sometimes will, overrule a past Supreme Court's 'settled' decisions."

Thomas appears to be experiencing a similar trajectory. His once-dissenting views on issues such as gun rights, abortion, and affirmative action have since been adopted into majority opinions. Like Field, Thomas' influence is expected to endure long after his departure from the bench.

Other Legal News: AI in Supreme Court Arguments

In a separate development, Supreme Court lawyer Neal Katyal recently sparked debate in the legal community after revealing that he used artificial intelligence as part of his preparation for oral arguments in a major case challenging President Donald Trump's tariffs. Katyal, who successfully argued against the tariffs, shared his experience in a viral social media post, crediting AI for enhancing his legal strategy.

The revelation has prompted discussions among legal professionals about the growing role of AI in legal practice. However, Katyal's boastful tone has also drawn criticism, raising questions about the ethical implications of AI use in high-stakes legal proceedings.
