Eleventh Circuit En Banc: Under-21 Firearm Purchase Bans Survive Bruen When Analogous to Founding-Era Minority Disabilities and Parental-Control Regimes

I. Introduction

Case: National Rifle Association v. Commissioner, Florida Dept. of Law Enforcement (11th Cir. en banc, Mar. 14, 2025).
Parties: The National Rifle Association and an 18–20-year-old member (ultimately substituted with another individual plaintiff) challenged Florida’s post–Parkland statute barring persons under 21 from purchasing firearms. The Defendant-Appellee was the Commissioner of the Florida Department of Law Enforcement, the official responsible for enforcement.
Legal backdrop: Florida enacted the Marjory Stoneman Douglas High School Public Safety Act after the Parkland shooting, codified at FLA. STAT. § 790.065(13), making it a felony for under-21 individuals to purchase firearms (with narrow occupational exceptions).

Core issue: Whether Florida’s under-21 firearm purchase prohibition violates the Second and Fourteenth Amendments for 18–20-year-olds in light of New York State Rifle & Pistol Ass'n v. Bruen and United States v. Rahimi.

II. Summary of the Opinion

The en banc Eleventh Circuit affirmed summary judgment for Florida. Applying Bruen as refined by Rahimi, the court held Florida’s restriction is constitutional because it is consistent with the Nation’s historical tradition of firearm regulation.

The court’s central move was to identify a Founding-era legal regime treating persons under 21 as “minors/infants” lacking full legal capacity—especially the capacity to contract and to control wages—thereby substantially limiting their ability to purchase firearms. The court viewed Florida’s purchase ban (while leaving avenues for access through parents or responsible adults) as sufficiently analogous in both “why” (immaturity/lack of judgment) and “how” (restricting acquisition via purchase) to fit within that tradition. The court further treated 19th-century statutes restricting sales to under-21 persons as confirming evidence.

III. Analysis

A. Precedents Cited

1. The governing Second Amendment framework: New York State Rifle & Pistol Ass'n v. Bruen and United States v. Rahimi

The opinion treats Bruen as establishing the controlling test: a firearm regulation is constitutional if it is “consistent with this Nation’s historical tradition of firearm regulation.” It then relies heavily on Rahimi’s methodological guidance—especially the instruction to compare the modern law to historical analogues by asking “why” and “how” the regulation burdens the right, and that a modern regulation need not be a “dead ringer” or “historical twin.”

The court also draws from Rahimi to rebut a maximalist historical requirement: the Founding’s absence of an on-the-nose statute does not prove the Founding generation rejected the regulatory power—rejecting a “use it or lose it” view of legislative authority (referencing Justice Barrett’s concurrence in Rahimi).

2. The individual-right baseline: District of Columbia v. Heller and McDonald v. City of Chicago

District of Columbia v. Heller supplies the baseline propositions that the Second Amendment protects an individual right, centrally tied to self-defense, but “is not unlimited,” and is informed by historical limits on the manner and circumstances of arms-bearing. McDonald v. City of Chicago is used to reiterate incorporation and to justify focusing on the same scope of the right against States and the federal government.

3. Historical period and interpretive method

On which history controls, the court emphasizes Founding-era understanding as primary, drawing support from the Court’s original-meaning approach in other amendments, including Crawford v. Washington, Virginia v. Moore, and Nevada Commission on Ethics v. Carrigan. It acknowledges post-ratification practice can sometimes “liquidate” meaning, citing Chiafalo v. Washington, but warns (with Heller and Bruen) that later history is generally less probative.

The court cites Espinoza v. Mont. Dep't of Revenue for the principle that later evidence may reinforce early practice but cannot create it.

4. Procedural posture and standard

The court reviews summary judgment de novo under Thai Meditation Ass'n of Ala. v. City of Mobile. It also characterizes the plaintiffs’ claim as effectively as-applied to 18–20-year-olds rather than a true facial challenge, invoking Moody v. NetChoice, LLC and United States v. Salerno.

5. The court’s engagement with dissents and adjacent doctrines

The majority accuses the dissents of smuggling in equal-protection-style scrutiny and responds with Gregory v. Ashcroft (age classifications generally get rational basis) and child-regulation cases like Ginsberg v. New York and Prince v. Massachusetts (states may regulate children more than adults even in rights-adjacent contexts). It also references voting-rights cases Harper v. Va. State Bd. of Elections and Oregon v. Mitchell to show that “fundamental” does not mean age lines are constitutionally forbidden.

B. Legal Reasoning

1. Defining the relevant “tradition”

The court holds the Founding era provides the principal benchmark. It declines to resolve fully whether 1791 or 1868 controls in a conflict because, in its view, both eras reflect restrictions on minors’ access to firearms. This is important: the court frames its holding as not dependent on choosing between Founding-era and Reconstruction-era understandings.

2. The court’s analogue: the Founding-era minority regime (contract incapacity + parental control)

The court’s key historical move is to treat under-21 persons as “minors/infants” at the Founding, who lacked legal capacity for many transactions and were subject to parental authority. The opinion emphasizes:

  • Contract incapacity and voidability: minors generally could not reliably contract for non-necessaries; sellers faced substantial risk; guns were not “necessaries.”
  • Lack of independent wages/disposable income: minors’ labor and wages typically belonged to parents, limiting independent purchasing power.
  • Parental-consent structure: minors’ meaningful access to goods (and rights) ran through parents/guardians.

The court then links these general legal disabilities to firearms acquisition: because purchasing a firearm is a contract transaction, the Founding-era legal framework effectively restricted purchase by under-21s.

3. Militia statutes as confirmatory evidence of limited self-directed purchasing

The opinion uses Founding-era and early state militia laws to reinforce that under-21 persons were expected to appear armed, but the obligation frequently ran through parents: many states required parents to furnish arms or made parents liable for minors’ militia-related fines. The court treats this as evidence that minors’ access to arms was structurally mediated by parental responsibility rather than free-market purchase by minors themselves.

4. University regulations and in loco parentis

The court cites university codes restricting possession of firearms and gunpowder, characterizing colleges as acting in loco parentis. These sources are used to show that, historically, institutions standing in for parents imposed meaningful restrictions on young persons’ weapons access.

5. Nineteenth-century statutes as making explicit what was implicit

The court then relies on mid-to-late-nineteenth-century statutes from many jurisdictions restricting sales/transfer of certain weapons to those under 21, often with criminal penalties, to bolster the conclusion that restricting under-21 purchases is within tradition. The majority uses these statutes as confirmatory evidence rather than as the core source of meaning.

6. Applying Rahimi’s “why” and “how”

“Why”: Florida’s law is justified, in the majority’s view, by the same underlying rationale as Founding-era limits on minors’ rights—under-21 persons have not reached the age of reason and are more likely to act impulsively; limiting purchases reduces risk of grave harm.
“How”: the law restricts only purchase, not all access—minors may still obtain firearms from parents/responsible adults; Florida’s law is framed as no more burdensome than the historical regime that required parental mediation.

7. Doctrinal guardrails the court announces (or reinforces)

  • Non-firearm-specific legal regimes can matter: the court rejects the idea that only firearm-specific statutes count, reasoning that common-law rules can be relevant analogues (invoking Rahimi’s use of surety and going-armed principles that were not limited to firearms).
  • Not a “historical twin” requirement: a modern statute may be upheld even if implemented through modern means (criminal ban) rather than the Founding’s civil-disability mechanisms, so long as it is “analogous enough.”
  • Rejecting a state-by-state “sliding adulthood” test: the court declines to let modern state age-of-majority lines dictate the Second Amendment’s scope, warning it would make a federal right vary with shifting state policy.
  • Assumption (not decision) on textual coverage: the court assumes, without deciding, that under-21 persons are within “the people” protected by the Second Amendment—citing the debate reflected in Lara v. Comm'r Pa. State Police.

C. Impact

  • Validates 21-and-over purchase lines (at least in the Eleventh Circuit): States within the circuit (and potentially elsewhere) gain a strong precedent supporting under-21 purchase bans—particularly those that restrict purchase while leaving pathways for possession through adult transfer.
  • Expands permissible analogue sources: The opinion is notable for treating a broad common-law minority regime (contract and parental authority) as a Second Amendment-relevant analogue, potentially widening the category of usable historical comparators after Bruen.
  • Deepens and sharpens the circuit split: The court expressly rejects the Fifth Circuit’s contrary approach in Reese v. Bureau of Alcohol, Tobacco, Firearms & Explosives, increasing the likelihood of Supreme Court review in under-21 firearms cases (including challenges to federal age-based sales restrictions).
  • Influences challenges to 18 U.S.C. § 922(b)(1): The reasoning supports age-based limits on purchase from licensed dealers (and arguably bolsters the constitutionality of Congress’s 21-year line for non-rifle/shotgun purchases), though the opinion’s holding is limited to Florida’s law.
  • Methodology signal: The concurrences (especially Judge Newsom’s) underline that post-ratification evidence is, at most, confirmatory; Judge Rosenbaum’s concurrence supplies additional pro-state arguments rooted in Reconstruction-era laws and modern neuroscience, which future litigants will cite even if the majority did not need them.

IV. Complex Concepts Simplified

  • “Historical tradition” test: Under Bruen, courts do not balance public safety against rights using modern “tiers of scrutiny.” Instead, they ask whether the modern restriction fits within historically accepted categories of regulation.
  • Analogical reasoning (“why” and “how”): Rahimi says courts compare (1) the reason the law exists (“why”) and (2) the method and severity of its burden (“how”) to historical predecessors.
  • Founding-era “minors” and contract law: Historically, under-21 persons often lacked full legal capacity to make enforceable purchases. The majority treats that framework as functionally limiting firearm purchases even without a direct “no sales to minors” statute.
  • Facial vs. as-applied challenges: A facial challenge claims a law is invalid in all applications; an as-applied challenge targets the law’s effect in a particular context. The court treated the plaintiffs’ claim as effectively limited to 18–20-year-olds.
  • In loco parentis: Institutions (like early universities) historically acted “in the place of parents,” which the court uses to show that restrictions on young persons’ weapon access were historically common.

V. Conclusion

The Eleventh Circuit’s en banc decision establishes that a state may constitutionally prohibit firearm purchases by persons under 21 when the restriction is justified and structured in ways the court deems consistent with Founding-era treatment of under-21 persons as legally immature—particularly through contract incapacity, parental authority, militia-related parental provisioning practices, and confirmatory 19th-century under-21 weapons-sale restrictions. The decision is methodologically significant for treating broad common-law frameworks as valid Bruen/Rahimi analogues and practically significant for sustaining under-21 purchase bans despite an active, developing inter-circuit conflict.
