Supreme Court will rule on ban on rapid-fire gun bump stocks, used in the Las Vegas mass shooting

The Supreme Court agreed on Friday to decide whether a Trump era-ban on bump stocks, the gun attachments that allow semi-automatic weapons to fire rapidly like machine guns, violates federal law.

The justices will hear arguments early next year over a regulation put in place by the Justice Department after a mass shooting in Las Vegas in 2017.

Federal appeals courts have come to different decisions about whether the regulation defining a bump stock as a machine gun comports with federal law.

Federal court strikes down Trump-era bump stock ban

A federal appeals court on Friday struck down the Trump-era ban on bump stocks, a firearm accessory that enables a semi-automatic gun to shoot at an increased rate of fire.

In a 13-3 decision, the 5th Circuit Court of Appeals in New Orleans held that the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), acting under "tremendous" public pressure, short-circuited the legislative process by approving a rule to define bump stocks as "machineguns," which are illegal to possess. The court said ATF did not have the authority from Congress to do so. 

The Bump Stock Ban Highlights the Danger of Letting Bureaucrats Invent Crimes

A federal appeals court rejects a highly implausible redefinition of machine guns.

Two years ago, peaceful, law-abiding gun owners across the country became felons overnight, thanks to the Trump administration's ban on bump stocks. But as the U.S. Court of Appeals for the 6th Circuit recognized last week, Congress alone has the authority to define new federal crimes, while the president and his underlings are charged with enforcing those laws.

Supreme Court leaves in place Trump ban on bump stocks

The Supreme Court on Monday declined to take up a bid by gun rights advocates to overturn a federal ban on bump stocks, devices which allow semi-automatic rifles to fire ammunition more rapidly.

The Trump administration outlawed the devices following the 2017 Las Vegas shooting in which a gunman used the rapid-fire accessory to carry out a massacre that killed 58 people and wounded hundreds in the deadliest shooting in U.S. history.
