Judge Rendell has announced her intent to take senior status, according to this article by Jeremy Roebuck of the Philadelphia Inquirer last night:
In July, Rendell will take “senior status” on the 13-member court, a designation that allows her to hear cases but reduces her workload. The decision clears the way for President Obama to appoint a full-time replacement before the end of his term.
There currently are 10 senior-status CA3 judges, Judge Scirica the most recent of them.
