Thomas Rex Lee

A 2016 paper written by Jeremy Kidd of the Mercer University Walter F. George School of Law and others attempted to measure the "Scalia-ness" of various potential nominees to the Supreme Court to fill the seat left vacant by Antonin Scalia's death. The study created a "Scalia Index Score" combining the various measures of "Scalia-ness," and Lee scored highest. The study found that Lee was the most likely to endorse or engage in originalism in judicial opinions, was second most likely to cite Scalia's non-judicial writings in opinions, and the third most likely to write separately when not writing the majority opinion. The study was updated again in 2018, adding new variables and more names, and Lee again scored the highest.

In a 2016 article, John McGinnis, of the Northwestern University School of Law, argued that Lee was similar to Scalia in being "capable of pressing the intellectual case for following the Constitution as written" because of Lee "has pioneered the application of corpus linguistics to law," and further wrote that if elevated to the U.S. Supreme Court, "Lee would create a transmission belt from the best work of originalists in the academy to the Supreme Court."

In his time on the court, Lee has been a prolific writer, authoring over a quarter of majority opinions on a five-member court, and frequently issuing concurring or dissenting opinions. Lee is a pioneer in law and corpus linguistics—the application of corpus linguistics to determine ordinary meaning in statutes—being the first American judge to do so in an opinion.

On May 28, 2010, Utah Governor Gary Herbert nominated Lee to fill the vacancy in the Utah Supreme Court left by the retirement of Michael J. Wilkins. Receiving a unanimous vote (5–0) from the Utah Senate Judicial Confirmation Committee in mid-June 2010, Lee was confirmed by the full Senate on June 23, 2010. Lee was sworn into office on July 19, 2010; his mentor, U.S. Supreme Court Justice Clarence Thomas, administered the oath.

Lee and his wife, Kimberly, have six children. His brother, Mike Lee, is a U.S. Senator representing the state of Utah. He is the son Rex E. Lee, a former Solicitor General of the United States and the 10th president of BYU.

Lee took leave of the JRCL from 2004 to 2005 to serve as Deputy Assistant Attorney General in the Civil Division of the United States Justice Department. While at the JRCL, from 2002 to 2004, Lee also served as the lead counsel in cases brought by the state of Utah in relation to plans to put nuclear waste on the Goshute Indian Reservation.

"Whereas some justices release a concurring or dissenting opinion in only a handful of cases that they hear," Lee is a prolific writer of such opinions, releasing them in around 16% of the Court's opinions. Of the ten Utah Supreme justices who served on the court from 1997 to 2012, Lee has the second-highest rate of dissent, filing dissenting opinions in 10% of cases over this time period. (The justice with the highest dissent rate was I. Daniel Stewart, who dissented 11% of the time). Lee also authored the highest proportion of majority opinions of the court (27%); Brown wrote that "[g]iven that Lee dissents relatively frequently, it is remarkable that he is also the most common author of majority opinions. His willingness to dissent has apparently not alienated his colleagues."

Lee then served as law clerk to J. Harvie Wilkinson, III of the United States Court of Appeals for the Fourth Circuit (1991–92). He then joined the firm of Kimball, Parr, Waddoups, Brown & Gee as an associate in 1992, before clerking for Clarence Thomas, Associate Justice of the United States Supreme Court (1994–95). He became a shareholder at Kimball, Parr, Waddoups, Brown & Gee in 1995, a position he would hold until 1997 when he left the firm to join the faculty of BYU's JRCL. At the law school, Lee taught courses in Civil Procedure and Intellectual Property Law, and a seminar on the United States Supreme Court. He also served as Associate Dean (2008-2010) and was named the Rex and Maureen Rawlinson Professor of Law. Following his 2010 appointment to the bench Lee has remained a Distinguished Lecturer in Law at the JRCL.

Thomas Rex Lee (born December 1964) is the Associate Chief Justice of the Utah Supreme Court. Lee is also a lecturer on law at Harvard Law School and an adjunct professor/distinguished lecturer at Brigham Young University's (BYU) J. Reuben Clark Law School (JRCL) since his appointment to the bench.

Thomas Rex Lee was born in 1964 to parents Janet (née Griffin) and Rex E. Lee. He grew up in Arizona, Utah and Northern Virginia. His undergraduate studies took place at BYU, graduating summa cum laude in 1988 with a bachelor's degree in economics. Lee graduated from the University of Chicago Law School with high honors in 1991.
