Judges are listed as Active or Senior (retired).
I've seen the distinction between Active and Senior here and on the 9th Circuit Court's website. However, I've seen no official explanation of difference, no confirmation that this judge was pulled out of retirement to server, and no verification that it was because of a vacancy caused by the Dems sitting on Bush's nominees.
Don't get me wrong, I think it is probably true. However, without sufficient verification I do not want to go around shouting this when it may turn out NOT to be true. If it is true, we truly have Daschle, Leahy, and the other obstructionist Democrats nailed on this issue.
