75 F.4th 563
5th Cir.2023Background
- ATF historically issued mixed letter rulings that pistol stabilizing braces did not convert pistols into rifles; brace use and market share grew substantially.
- In 2021 ATF proposed Worksheet 4999 (a points-based, objective test) to determine when a brace makes a pistol a rifle; after heavy public comment ATF published a 2023 Final Rule discarding the Worksheet and adopting a six-factor, largely subjective balancing test.
- The Final Rule amended ATF regulations, estimated large economic impacts and that ~99% of braced pistols would become short-barreled rifles (SBRs), and set a compliance grace period ending May 31, 2023 with several remediation options (including NFA registration).
- Plaintiffs (two individual owners, Maxim Defense, and Firearms Policy Coalition) sued seeking injunctive relief alleging APA, statutory, and constitutional defects; the district court denied a preliminary injunction.
- The Fifth Circuit (majority) reversed the denial, holding the Final Rule is a legislative rule and not a logical outgrowth of the Proposed Rule, so it likely violates the APA; the case was remanded for the district court to decide remaining preliminary-injunction factors and scope of relief, while the court maintained an interim injunction pending that ruling.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the Final Rule is legislative (subject to notice-and-comment) or merely interpretive | Final Rule imposes binding legal effects and affects rights; it is legislative | Rule interprets statutes and is therefore interpretive and not subject to additional procedural constraints | Final Rule is legislative; it has force of law and was published in C.F.R., so APA notice-and-comment applies |
| Whether the Final Rule is a logical outgrowth of the Proposed Rule (notice adequacy) | Replaced objective Worksheet with a subjective six-factor balancing test not fairly foreseeable—so no fair notice | Final Rule derives from NPRM criteria and public comments; commenters criticized the Worksheet and thus ATF reasonably revised approach | Final Rule is not a logical outgrowth; replacing the Worksheet with the six-factor test without new notice violated APA |
| Whether plaintiffs’ statutory/nondelegation/lenity challenges require resolution now | ATF exceeded statutory limits; ambiguity warrants lenity; nondelegation concerns | ATF has delegation from AG and authority to clarify implementation | Court declined to decide statutory and constitutional claims because plaintiffs likely prevail on their APA claim; it left those issues for merits proceedings |
| Scope and duration of injunctive relief | Plaintiffs sought extension/nationwide injunction and continuation of interim relief | Government urged limited or no injunction | Court reversed denial of PI, remanded to district court to assess irreparable harm, equities, public interest and scope; maintained interim injunction pending district court ruling (60-day limit) |
