According to the latest vacancy data from the U.S. Courts, there were 27 total announced upcoming vacancies for Article III judgeships as of January 5, 2022. Article III judgeships refer to federal judges who serve on the U.S. Supreme Court, the U.S. Court of International Trade, or one of the 13 U.S. courts of appeal or 94 U.S. district courts. These are lifetime appointments made by the president and confirmed by the U.S. Senate.
These positions are not yet vacant but will be at some point in the future with every judge having announced his or her intent to either leave the bench or assume senior status. In the meantime, these judges will continue to serve in their current positions.
The president and Senate do not need to wait for a position to become vacant before they can start the confirmation process for a successor. For example, Rachel Bloomekatz was nominated to replace Judge R. Guy Cole who retires on Jan. 9, 2023. There are currently 6 nominees pending for upcoming vacancies.
