State court? You must be new to this game. There is a reason it's called the Supreme Marsupial Court.
Remember, the state courts have upheld decisions like "an expired RO with no violation thereof may be used as a lifetime ban", "charges you are acquitted of may be used as the basis to deny gun rights" and "exercising your right to remain silent when questioned is a valid reason to revoke an LTC". Then there is the LONG history of deciding that gun rights are collective, not individual, and that the 2A applies only to technologies extant at the time of its writing.
Although it goes back to 1976, the Davis case is a classic example of what the court feels it its role in the gun control issue. There was a ballot initiative to ban handguns, so the SJC took up a case before the vote specifically so they could issue a ruling that the right is collective, not individual. Apparently, they thought the govt needed to give itself permission to arm its militia.
