1. Reversals
There have been more cases from the Ninth Circuit to the Supreme Court than any other circuit in recent years. There have also been more cases decided by the Ninth Circuit in recent years than any other circuit. As set forth in the study by the Honorable Jerome Farris, a Ninth Circuit judge recently senior, in 1995 the Ninth Circuit decided 7,955 matters, in 1996 7,813, and in 1997 8,701. The percentage of reversals as against the total number of cases decided was 3/10 of 1%.

During the last several years, Supreme Court reversal rates of Ninth Circuit decisions have been consistent with that of other circuits. For example, during this past term, on a percentage basis, there were seven other circuits whose reversal rates exceeded ours. Perhaps more importantly, the number of petitions for certiorari granted by the Supreme Court arising out of decisions of the Ninth Circuit has declined significantly in recent years.
Even in the year most frequently cited by critics, 1996, our circuit was not the most reversed circuit on a percentage basis. That year, five circuits had all of their decisions reversed: the First, Second, Seventh, D.C., and Federal circuits. And since that time, we've had 14 new members added to our court.
All of this indicates that our opinions are receiving an appropriate amount of internal examination, and the consistency of our opinions does not vary from that of other circuits.
