The United States Supreme Court ruled 6-3 on Friday to overturn a federal regulation that banned bump stocks, the firearm attachments that allow semi-automatic weapons to fire at speeds mimicking machine guns. Writing for the majority, Justice Clarence Thomas stated that the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) exceeded its authority by reclassifying the devices as prohibited machine guns. The ruling reverses a 2018 policy implemented under the Trump administration following the mass shooting in Las Vegas. While gun rights advocates praised the decision as a victory for the rule of law and legislative clarity, gun control proponents and the Biden administration expressed concern that the ruling could impact public safety. President Biden has since called on Congress to pass a permanent legislative ban, emphasizing that the decision 'undermines the progress' of firearm safety measures. Legal analysts suggest the ruling focuses narrowly on statutory interpretation rather than the Second Amendment itself, placing the responsibility for future regulation directly on federal lawmakers.
