In a 7-2 decision written by Justice Neil M. Gorsuch, the justices allowed 2022 rules from the Bureau of Alcohol, Tobacco, Firearms and Explosives that require serial numbers, sales receipts and background checks for the weapons, which are typically purchased online as kits that let the buyer complete assembly at home. Justices Samuel A. Alito Jr. and Clarence Thomas dissented in separate opinions.

Writing for the court majority, Justice Neil Gorsuch said that under the broad language of the 1968 Gun Control Act, the ATF was well within its authority in requiring those who make or sell gun kits to mark their products with serial numbers, keep records of their sales, and conduct background checks on buyers.
