The United States Court of Appeals for the Sixth Circuit (in case citations, 6th Cir.)
Four other judges of the Sixth Circuit have been elevated to serve on the Supreme Court, the last being Potter Stewart in 1958.
The chief judge serves for a term of seven years, or until age 70, whichever occurs first.
The court has 16 seats for active judges, numbered in the order in which they were initially filled.
Judges who assume senior status enter a kind of retirement in which they remain on the bench but vacate their seats, thus allowing the U.S. President to appoint new judges to fill their seats.
