86 F.4th 179
5th Cir.2023Background
- In April 2022 ATF issued a Final Rule redefining “frame or receiver” to include partially complete, disassembled, or nonfunctional frames/receivers and expanding “firearm” to include weapon parts kits (so-called “ghost‑gun” parts).
- Plaintiffs (VanDerStok et al. and several industry/advocacy intervenors) sued in the N.D. Tex., challenging those two portions as exceeding ATF’s authority under the Gun Control Act (GCA).
- The district court granted summary judgment for plaintiffs, held the two challenged definitions unlawful, and vacated the Final Rule in full; lower‑court injunctions followed.
- On appeal the Fifth Circuit reviewed de novo, emphasizing statutory text as the controlling inquiry under the APA and criminal‑law interpretive canons (including the rule of lenity).
- The Fifth Circuit affirmed that (1) ATF exceeded statutory authority in redefining “frame or receiver” to reach unfinished components and (2) ATF unlawfully expanded “firearm” to cover weapon parts kits; but it vacated the district court’s universal vacatur and remanded the remedy question.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether ATF lawfully redefined “frame or receiver” to include partially complete, disassembled, or nonfunctional components | VanDerStok: GCA’s plain text and ordinary meaning of “frame or receiver” do not include parts not yet functioning as a frame/receiver; ATF exceeded §926(a) authority | ATF/Garland: modern firearms and PMFs make prior definitions obsolete; agency may interpret and update definitions to effectuate the statute | Unlawful — Court held ATF lacked congressional authorization to expand the term; the Final Rule conflicts with the statutory text and ordinary meaning. |
| Whether ATF lawfully expanded “firearm” to cover weapon parts kits | Plaintiffs: Congress omitted broad “parts” regulation when enacting the GCA; prior statutes show Congress knew how to regulate parts and chose not to | ATF: "may readily be converted" language in GCA and public‑safety needs capture kits; precedent supports treating some disassembled items as firearms | Unlawful — Court held the GCA’s structure and text limit regulation to frames/receivers (and specified items), so ATF cannot treat aggregations of parts as firearms. |
| Proper remedy for unlawful rulemaking (vacatur vs. narrower relief) | Plaintiffs: vacatur of the unlawful rule (district court did so) | Government: full vacatur overbroad; request narrower relief or remand limited to unlawful provisions | Mixed — Merits rulings affirmed for the two challenged provisions; the district court’s full vacatur was VACATED and the remedy was REMANDED for further consideration. |
