However, the Ninth Circuit has shown itself to be hostile to the Second Amendment.
In spite of President Trump's appointments to the Ninth, there still appears to be a majority of Progressive judges on the court, who want to essentially nullify Heller.
I expect the Ninth to uphold this decision, then an appeal be made to the Supreme Court.
Whether the SCOTUS decides to take the case will probably depend on whether RBG is still on the court, and if President Trump has appointed a replacement.
