The 9th also struck down the ammunition background check requirement in their adjudication of Rhode v. Bonta.
And it also ruled that the 2A is incorporated against the states (in one of the Nordyke cases), before the Supreme Court did it in
MacDonald. The oft-repeated trope that the 9th circuit is anti-gun is not completely correct.
Will they be overturned in our lifetimes though? I'm sure plenty of people thought Roberti-Roos would be overturned when it was signed into law in 1989.
In 1989, the controlling case for the 2A was
Miller. In those days, it was generally thought that the 2A only applies to the militia, not to individuals. Note how few court cases used the 2A itself to fight for gun rights back then; even the ones that gun right advocates won (such as
Harrott) were not 2A based. This completely changed with
Heller in 2007 or 2008, when Justice Scalia's opinion stated clearly that the 2A applies to individuals, at least as far as self-defense in the home is concerned. That decision (plus incorporation in
MacDonald) was a complete sea change for 2A jurisprudence. Heller is really what the expansion of gun rights is based on.
Now, originalists might claim "but the 2A never changed, it always meant what I want it to mean". Sorry, that's not the way our legal system works (unless your first name is Clarence). The constitution and tradition give the courts the responsibility to interpret what laws and the constitution mean (see
Marbury). After
Miller, the 2A meant one thing. After
Heller, it meant a different thing. Panta rhei.
That document is written not by a court, but by one of the more out-there advocacy organizations. Actually, also one of the more corrupt ones; the SAF is to a large extent a machine to enrich Alan Gottlieb and his family; doing 2A advocacy is a means to an end. And whipping up the anger of the true believers is good for SAFs fundraising success.
