On October 8, the Supreme Court will hear oral argument in Garland v. VanDerStok, a challenge to the Final Rule of the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF) from 2022 redefining and drastically expanding the meaning of the terms "firearm" and "firearm frame or receiver." This is the first of several posts in which I'd like to highlight some of the enlightening amici curiae briefs that have been filed in support of the respondents who challenged the rule.
The Gun Control Act defines "firearm" as "(A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon…." 18 U.S.C. § 921(a)(3). An ATF regulation on the books from 1968 to 2022 defined a "frame or receiver" as "that part of a firearm which provides housing for the hammer, bolt or breechblock and firing mechanism" – in other words, to main part of the firearm to which the barrel and stock attach.
The Final Rule expanded "firearm" to include "a weapon parts kit that is designed to or may readily be completed, assembled, restored, or otherwise converted to expel a projectile by the action of an explosive." And it redefined "frame or receiver" to include "a partially complete, disassembled, or nonfunctional frame or receiver" that is "designed to or may readily be completed, assembled, restored, or otherwise converted to function as a frame or receiver."
