In his twenty terms as an associate justice of the Supreme Court of the United States, Clarence Thomas has written nearly 450 opinions. Although they are readily available to the American people, much of the public continues to base its view of Thomas merely on reporting of the media. This analysis of Thomas"s most important majority, concurring, and dissenting opinions offers laypersons and legal professionals alike the opportunity to understand in his own words Thomas"s approach to constitutional decision-making and his understanding of the most important provisions of the Constitution. Thomas"s opinions, this work shows, reveal his consistent adherence to the core principles of federalism, separation of powers, and restrained judicial review, and to the regard for individual rights and limited government embodied by the Founders in the Constitution.
