The justice who wrote the primary opinion, Patrick Bumatay was a Trump appointee, while the other two concurring justices were a Reagan appointee (Diarmuid O'Scannlain) and another Trump appointee (M.Miller Baker).
This one almost certainly will be overturned by the full Ninth Circuit next, and who knows if the Supreme Court takes this one.
The Ninth Circuit does not take a ton of cases en banc (certainly not every case that happens to draw a conservative panel), and its unique en banc procedure means that it is very possible to draw a conservative-leaning en banc panel.
How does its procedure different from other circuits?
