In 1934 the National Firearms Act placed a stamp tax and registration requirements on certain classes of firearms. In 1986 the Firearm Owners Protection Act included a provision known as the Hayes Amendment which closed the federal registry to new full-auto firearms. So if you wanted to own a new full-auto firearm, if you don’t register it you’re in violation of the NFA; but the government won’t let you register it.
“Regulate something- then make it impossible to meet the requirements”. Turning regulation into a de facto ban. Has the Supreme Court, or any lower or state court, ever addressed the legality of this general tactic?
