The June 8, 2009 edition of Missouri Lawyers Weekly (not available online) reports that only 1 out of the 17 current judges sitting on the United States Eighth Circuit Court of Appeals are women. Her name is Diana Murphy and she was appointed by a Republican. All nine of the appointments to the 8th Circuit since 1994 (when Murphy was appointed) have been men. Each of these appointments is made by the President of the United States.
To put this in context, 47% of the people receiving law degrees in 2007 have been women. Another note: Of the 179 total judges sitting on the 11 U.S. Courts of Appeals, 26% of them (47) are women.
