The Supreme Court ruled on June 14 that the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) exceeded its authority when it interpreted a federal firearms statute to outlaw the use of bump stocks.
“We conclude that [a] semiautomatic rifle equipped with a bump stock is not a ’machinegun‘ because it does not fire more than one shot ’by a single function of the trigger,'” Justice Clarence Thomas wrote in the court’s majority opinion.
