Do you think the 9th Circus will uphold the Judges ruling?
Tough to say. It seems likely the three judge panel will uphold the permanent injunction.
I give it good odds the three judge panel will uphold the District Court verdict.
Then, what has been happening is the Ninth will authorize an en banc hearing. The en banc hearings have generally gone against the Second Amendment.
It may not happen this time, because President Trump is appointing some replacements for the Ninth.
I have not read the opinion, but have read it is a very good one.
I give it a slightly better than 50% chance of being upheld at the Ninth Circuit.
