The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) lacked the authority to declare non-mechanical bump stocks “machineguns,” the full Fifth Circuit Court of Appeals held on Friday.
The decision, Cargill v. Garland, is the latest example of the courts foiling attempts by the federal bureaucracy to exercise the legislative power the Constitution vests with Congress, but until the Supreme Court’s separation of powers jurisprudence catches up with the runaway administrative state, the Cargill victory holds limited import.
On Oct. 1, 2017, a gunman murdered more than 50 innocent people in Las Vegas, injuring another 500. The murderer used several weapons, many of which had bump stocks attached. A bump stock, as the court in Cargill explained, “is a firearm attachment that allows a shooter to harness the natural recoil of a semi-automatic weapon to quickly re-engage the trigger after firing, enabling him to shoot at an increased rate of speed.”
