The Supreme Court ruled 7-2 on March 26, 2025 that the Bureau of Alcohol, Tobacco, Firearms and Explosives has statutory authority to require serial numbers and background checks on so-called 'ghost gun' weapon parts kits that can be readily assembled into functional firearms. The ruling in Garland v. VanDerStok was confirmed by Fox News, NPR, the Associated Press, CNN, and the National Rifle Association's own reporting.

Justice Amy Coney Barrett wrote the majority opinion, joined by Chief Justice Roberts and Justices Sotomayor, Kagan, Kavanaugh, Gorsuch, and Jackson. The court held that a weapon parts kit qualifies as a 'firearm' under the Gun Control Act when it is 'designed to or may readily be converted' into an operable weapon. Justices Thomas and Alito dissented, arguing the court had gone beyond what Congress authorized the ATF to regulate.

The ATF rule at issue, finalized in April 2022, came amid a surge in ghost gun recoveries at crime scenes. The Biden administration reported that ghost gun recoveries by law enforcement increased 1,000% from 2017 to 2021, with more than 20,000 reported to the ATF in 2021 alone. The rule required manufacturers and dealers to serialize the kits and conduct background checks on buyers.

NPR, CNN, and gun-control advocates celebrated the ruling as closing a significant loophole in federal gun law. Fox News and the Daily Wire noted that the decision was narrowly about statutory interpretation — whether Congress had authorized the ATF rule — and not about the Second Amendment. The Second Amendment Foundation and Firearms Policy Coalition said they would pursue further challenges on constitutional grounds.
