WASHINGTON — 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.
The justices said they will review the Biden administration’s appeal of a ruling by the 5th U.S. Circuit Court of Appeals in New Orleans that invalidated the ban.
The Supreme Court already is weighing a challenge to another federal law that seeks to keep guns away from people under domestic violence restraining orders, a case that stems from the landmark decision in 2022 in which the six-justice conservative majority expanded gun rights.
The new case is not about the Second Amendment right to “keep and bear arms,” but rather whether the Trump administration followed federal law in changing the bump stock regulation.
The ban on bump stocks took effect in 2019. It stemmed from the Las Vegas shooting in which the gunman, a 64-year-old retired postal service worker and high-stakes gambler, used assault-style rifles to fire more than 1,000 rounds in 11 minutes into a crowd of 22,000 music fans.
Most of the rifles were fitted with bump stock devices and high-capacity magazines. A total of 58 people were killed in the shooting, and two died later. Hundreds were injured.
The Trump administration’s ban on bump stocks was an about-face for the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. In 2010, under the Obama administration, the agency found that a bump stock should not be classified as a machine gun and therefore should not be banned under federal law.
Following the Las Vegas shooting, officials revisited that determination and found it incorrect.
