...They are overturned 80% of the time...
In other words, of every ten day decisions they make, eight of those are wrong. Not even close enough for government work.
You are correct. In what other job can you screw up that badly and still be employed?
80% of the 9th circuits decisions are not overturned. 80% of the 9th circuits cases appealed to SCOTUS, and for which SCOTUS grants cert, are overturned. Only a small fraction of their decisions are appealed.
Still a horrible record.
