In US District Court in the D.C. Circuit, DC’s restrictions on guns as they currently are have been upheld. You can find the opinion here. I think this is wrong, but it’s worth noting that the original Heller case, then known as Parker v. DC failed at the District Court level too, but won on appeal. No guarantee this happens here, however.
For a lot of reasons, I’m not too enthusiastic about proceeding forward at this point with challenges to assault weapons bans. Let’s get the court to say a bit more about the right first, before opening that whole can of worms. I agree the common use test here should easily protect them, but just because it’s correct doesn’t mean that’s what the courts will do.
UPDATE: Just skimming, this is an awful ruling. No attempt was made to determine whether DC’s state public safety goals with their ridiculous gun control scheme could be achieved with a lesser level of infringement. It’s hard to see what gun control law would fail this level ofÂ scrutinyÂ applied by the District Court.
