Judge Marsha Berzon of the U.S. Court of Appeals for the Ninth Circuit announced on Tuesday that she would be taking senior status after 21 years on the court.

Berzon, a San Francisco-based judge who was nominated by President Bill Clinton, is the second judge on the circuit to announce her semi-retirement in the last month. On Feb. 11, fellow Ninth Circuit Clinton-nominee Judge Susan Graber, who is based in Portland, Oregon, announced that she would be retiring from regular service when a successor is confirmed. The notice from Berzon, who will also go senior upon confirmation of her successor, leaves two future vacancies on the court.
