Ancillary case:
http://www.scotusblog.com/case-files...s-association/
The case above has zero to do with the Second Amendment directly; but instead challenges the government's power to regulate via interpretive rulemaking in accordance with the Administrative Procedures Act. As such, the outcome has the potential to affect such issues as the current ATF 41P proposal, import of 922(r) items, straw purchase rules from Abramski, etc.
It is headed to SCOTUS this December.
