Sifting through the data for what you care about most, timing & results:
Table B4-A -- Median Time Intervals:
From notice of appeal to opinion in appeals from district courts to the 9th Circuit = 13.1 months overall and 19.5 months for civil appeals [yes, the slowest Circuit by over seven months]: 10.5 of those months being the waiting time from the last brief until oral argument/submission [yes, this is by FAR the slowest of all the circuits -- the next slowest is the 4th Circuit 4.8 months] and 1.5 months waiting time from argument to opinion.
Table B5 -- Appeals Terminated on the Merits (i.e., outcomes!):
Overall 9th Circuit reversal rate = 8.3%
For appeals involving the United States = 15.4%
For private civil appeals = 18.1%
