This is more a 14th Amendment case, but the State Appeals Court tossed a conviction for having an unlicensed gun, arguing that it violated equal protection, and his right to bear arms. Eugene Volokh notes:
This independent focus on the Second Amendment is important because the Supreme Court has read the Equal Protection Clause as barring most (but not all)Â stateÂ discrimination against noncitizens; the federal government remains generally free to discriminate against noncitizens. But if the Washington Court of Appeals is right that legal aliens are protected by the Second Amendment, that means that even the federal government may not ban them from owning guns.
This would basically mean that anyone who’s in the country legally has a right to bear arms. Current federal law severely curtails the right for non-resident aliens, so this could be interesting if it makes its way to federal court.
