DOJ’s refusal to enforce under-21 handgun sales ban sets up powers fight

The Justice Department will not criminally enforce a federal law barring federally licensed firearms dealers from selling handguns to adults under 21, relying on an Office of Legal Counsel opinion that found the restriction violates the Second Amendment.¹

The decision, reported Friday by Axios, puts the executive branch in the position of declining to enforce a statute enacted by Congress while it remains on the books and courts continue to weigh challenges to age-based handgun restrictions.² DOJ said its position applies to otherwise law-abiding adults ages 18 to 20 and to licensed dealers who sell handguns to them.¹

The move is not a court ruling and does not erase 18 U.S.C. § 922(b)(1) or § 922(c)(1), the provisions that restrict handgun sales by licensed dealers to people under 21. Instead, it signals that federal prosecutors will not bring criminal cases under those provisions against licensed sellers in the covered circumstances.³

That distinction is central to the dispute. Courts, not the executive branch, issue binding constitutional judgments that invalidate federal statutes. But administrations also make enforcement judgments, including whether to defend or prosecute under laws they view as unconstitutional. Here, the Trump administration is using an internal constitutional analysis to suspend criminal enforcement of a firearms law Congress passed more than five decades ago, setting up a fight over the limits of executive non-enforcement authority.²

What DOJ said

The Justice Department said the Office of Legal Counsel concluded that the federal ban on licensed handgun sales to 18-, 19- and 20-year-olds cannot constitutionally be enforced against otherwise law-abiding adults in that age group.¹ DOJ characterized the OLC opinion as binding within the executive branch for federal enforcement purposes, but it is not binding on courts.

The policy affects federally licensed firearms dealers, the businesses regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives. The law has long prohibited those dealers from selling handguns to buyers under 21, even though adults 18 and older may legally possess handguns in many circumstances under state and federal law.³

Axios reported that ATF’s public dealer guidance still reflected the under-21 handgun sales restriction after DOJ’s announcement, underscoring the uncertainty for gun dealers, state officials and litigants until the agency updates its instructions or issues new compliance material.²

The Washington Examiner reported that the non-enforcement position is based on a 49-page OLC opinion. It said the immediate enforcement consequence is that federally licensed dealers would not face federal criminal prosecution for covered sales to otherwise eligible adults ages 18 to 20.⁷

A separation-of-powers dispute

The administration’s position raises a familiar but high-stakes question: When the executive branch believes a federal statute is unconstitutional, may it stop enforcing the law before the judiciary has struck it down?

Supporters are likely to frame the move as an obligation not to enforce unconstitutional laws. DOJ’s announcement placed the decision within the administration’s broader view that the Second Amendment protects adults under 21 who are otherwise eligible to buy firearms.¹

Opponents say the executive branch is bypassing Congress and the courts. GIFFORDS Law Center said the administration was choosing to ignore a law enacted by Congress rather than defend and enforce it, casting the decision as an unlawful attempt to let under-21 buyers obtain handguns through licensed dealers.⁶

The dispute is not only about gun policy. It also concerns institutional power: Congress wrote the age restriction into federal law, the executive branch is charged with enforcing it, and the judiciary decides whether the statute is constitutional in cases before the courts. By halting criminal enforcement through an internal legal opinion, DOJ has changed the statute’s practical operation without a final judicial ruling.²

ATF guidance is the next practical question

For firearms dealers, the next question is what ATF says in formal guidance. Dealers rely on ATF publications, inspection practices and compliance instructions to determine what sales are lawful and what conduct could expose them to penalties.

Axios reported that ATF’s published guidance still said licensed dealers may not sell handguns to people under 21, even after DOJ announced its non-enforcement position.² That creates a gap between DOJ’s new criminal enforcement policy and existing public-facing dealer materials.

Until ATF updates that guidance, dealers may face uncertainty over whether the government’s position affects only criminal prosecution or also changes licensing, inspection or administrative consequences. DOJ’s announcement addressed criminal enforcement; it did not rewrite the statute or act as a judicial injunction against ATF enforcement activity.¹

That distinction matters because federal firearms regulation operates through both criminal penalties and administrative oversight of licensed dealers. If ATF updates its materials to reflect DOJ’s position, the policy change would become more visible to the regulated industry. If it does not, confusion could persist over how dealers should treat buyers ages 18 to 20.

Litigation impact, but not precedent

The Justice Department’s position is likely to affect active Second Amendment litigation over age-based gun restrictions, though it does not resolve those cases.

Bloomberg Law reported that the memo connects to ongoing challenges involving young adults and firearms access, including disputes over whether historical tradition supports limiting handgun purchases by 18- to 20-year-olds.⁵ The Supreme Court has previously declined to take up the issue, leaving lower courts to continue developing the law.⁵

The Associated Press reported that courts have been divided on the question, creating a circuit split over restrictions affecting young adults and firearms.³ That split remains for the judiciary to resolve.

CBS News noted that the OLC opinion does not create judicial precedent, even though it is likely to shape federal charging decisions and the government’s posture in court.⁴ In pending cases, litigants challenging age restrictions may cite DOJ’s conclusion as persuasive support, while defenders of the law may argue that only courts can invalidate an act of Congress.

The department’s new position could also change how the federal government defends the statute in lawsuits. If DOJ now views the law as unconstitutional, it may decline to defend it, confess error or take positions that make it harder for the statute to survive in federal court. That could invite states, advocacy groups or other parties to seek intervention where available to defend similar age restrictions or related regulatory schemes.

For now, the under-21 handgun sales restriction remains written into federal law. What has changed is the federal government’s willingness to prosecute licensed dealers under it — a policy choice with immediate enforcement consequences and broader implications for the balance of power among Congress, the executive branch and the courts.
