So far in 2024, four federal circuit court judges have announced their intention to take senior status upon the confirmation of their successor, including (most recently) Judge Jane Stranch of the U.S. Court of Appeals for the Sixth Circuit. The others are Judges Charles Wilson (11th), Ilana Rovner (7th), and James Wynn (4th).
Including Judge Stranch, whose intentions were just reported today, this means there are ten current and pending vacancies on the federal circuit courts of appeals. Four of these seats have pending nominees.
Ten appellate seats to fill in the final year of a presidential term is a tall order, but I suspect Senate Democrats can get it done if they are willing to devote the floor time to it. In the absence of significant legislation, there will be political pressure to move on appellate judges.
