There are two cases that may or may not reach a decision in the 9th Circuit.
The first is Peruta v. San Diego. The other case is Richards v. Prieto (was Sykes v. McGinness). These cases both challenge the discretionary issue of carry licenses ("good cause"). The Peruta challenge was dismissed on the defendants MSJ. The Judge cited that Unloaded Open Carry (UOC) was enough to satisfy the 2A. The Judge in Richards thereafter ruled much the same.
Now however, the law in CA has changed and UOC has been banned. That pretty much moots the opinions of the two Judges. It remains to be seen if the 9th will kick this back to the District Courts. The odds are 50/50 that they will.
Enos (the MCDV case) has just started briefing at the 9th.
The other CA cases are still at District Court.
In other words, I don't think it will have much if any effect. Not for a while, at any rate (hoping I'm wrong).
