On December 6, 2021, the US Tax Court announced that Adam B. Landy and Eunkyong Choi have each been selected to serve as Special Trial Judges (STJs). They join the existing members of the Tax Court, which include four other STJs, 17 presidentially appointed Judges, and 10 Senior Judges serving on recall.

STJ Landy was previously in private practice in South Carolina from 2010 to 2016 and was a Senior Attorney with the Internal Revenue Service Office of Chief Counsel (in San Francisco and Baltimore) from 2016 until he joined the Tax Court. STJ Choi was also previously in private practice and spent time both teaching and working at low-income taxpayer clinics and serving as the Taxpayer Advocate in the New York City Department of Finance before she joined the Tax Court.

The purpose of STJs is to lessen the workload of the Tax Court and to allow the judges to hear cases with smaller amounts in controversy. The duties of STJs are wide-ranging and include several activities, as reflected in a prior Position Vacancy Announcement.
