Pamela Bondi, Attorney General, et al., Petitioners v. Jennifer VanDerStok, et al.

This case determined whether the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) acted within its authority under the Gun Control Act of 1968 when it issued a rule regulating "ghost guns"—weapon parts kits and unfinished frames that can be readily assembled into functional firearms. The Supreme Court upheld the ATF's rule, finding that such kits and components fall within the statutory definition of a firearm.
