United States v. Castleman: Domestic Violence Firearm Ban

In United States v. Castleman, 572 U.S. 157 (2014), the Supreme Court held that “physical force” in the federal ban on firearm possession by people convicted of misdemeanor domestic violence means the same thing as force in a common-law battery: any offensive touching, not just violent aggression.¹ The decision meant that pushing, grabbing, or slapping an intimate partner can be enough to trigger a lifetime federal prohibition on owning guns or ammunition, and it resolved a split among lower courts that had been reading the statute far more narrowly.

How the Case Reached the Supreme Court

James Alvin Castleman pleaded guilty in 2001 to a Tennessee misdemeanor: intentionally or knowingly causing bodily injury to the mother of his child.¹ Years later, federal authorities found he was selling firearms on the black market and charged him under 18 U.S.C. § 922(g)(9), which bars anyone convicted of a “misdemeanor crime of domestic violence” from possessing firearms or ammunition.²

The lower courts disagreed on whether his Tennessee conviction actually qualified. That disagreement went to the heart of how broadly the federal ban should reach.

The Fight Over What “Physical Force” Means

Castleman’s defense pointed to Johnson v. United States, in which the Supreme Court read “physical force” in the Armed Career Criminal Act to require violent force capable of causing pain or injury. Under that standard, only serious physical aggression would count, and many ordinary domestic battery convictions would escape the federal firearm ban.

The government argued the opposite. Tennessee’s domestic assault statute covers not only bodily injury but also “provocative or offensive contact.”³ Requiring Johnson-level violence would gut the Lautenberg Amendment, since a large share of state domestic assault laws sweep in low-level contact.

The Court’s Holding

Justice Sonia Sotomayor, writing for the majority, sided with the government. “Physical force” in § 922(g)(9) carries its common-law meaning: the degree of force that supports a battery conviction, which is any offensive touching.¹

The Court drew a firm line between how “force” reads in different statutes. In violent-felony provisions, the word “violence” implies a substantial degree of force. But “domestic violence” is a legal term of art that covers acts most people would not describe as “violent” outside a family setting. The Court observed that domestic abuse often escalates: what looks like minor physical contact can be a step toward severe or lethal harm. Reading the statute to demand dramatic force would have hollowed out the very protection Congress built into the law.¹

Because Castleman had pleaded guilty to intentionally or knowingly causing bodily injury, his conviction necessarily involved the use of physical force under this common-law standard. His federal firearm charges stood.

Which Convictions Trigger the Federal Firearm Ban

Not every misdemeanor assault conviction counts. Under 18 U.S.C. § 921(a)(33)(A), a qualifying offense must meet requirements about the nature of the crime, the relationship between the parties, and the fairness of the original prosecution.

The Relationship Between the Parties

The offense must have been committed against someone in a specific domestic relationship with the offender: a current or former spouse, a parent or guardian of the victim, someone who shares a child with the victim, or a person cohabiting or who has cohabited with the victim as a spouse, parent, or guardian.⁴ Assaults between strangers or casual acquaintances do not count, even if the conduct was identical.

The Bipartisan Safer Communities Act of 2022 expanded that list to include people in a current or recent former dating relationship, defined as a continuing serious relationship of a romantic or intimate nature. Courts weigh how long the relationship lasted, its nature, and how frequently the individuals interacted. Casual encounters do not qualify.⁴

Procedural Safeguards

The original misdemeanor prosecution must also have met basic due process standards. The defendant must have been represented by counsel or knowingly waived that right, and if the offense was eligible for a jury trial, must have received one or waived it.⁴ Without those safeguards, the conviction cannot support a federal firearm charge no matter how serious the underlying conduct.

How Courts Match State Convictions to the Federal Definition

Federal judges do not look at what actually happened during the domestic incident. They use the categorical approach, comparing the legal elements of the state offense to the federal definition. If every way of violating the state statute also satisfies the federal standard, the conviction qualifies.

When a state statute is “divisible” and lists several alternative ways to commit the offense, courts apply the modified categorical approach. Judges can then review a narrow set of court records, such as the charging document and plea documents, to identify which version of the offense the defendant was actually convicted of.¹ The inquiry stays focused on the elements of conviction, not the facts of the incident.

Reckless Conduct After Voisine

Castleman had pleaded guilty to intentional conduct, but many domestic assault convictions rest on recklessness. In Voisine v. United States (2016), the Supreme Court held that a reckless domestic assault conviction also satisfies the “use of physical force” requirement.⁵

The reasoning was practical. When Congress enacted § 922(g)(9) in 1996, 34 states plus the District of Columbia defined misdemeanor assault to include reckless infliction of bodily harm. Excluding reckless conduct would have made the law inoperative across most of the country. The Court emphasized that recklessness involves a conscious decision to disregard a known risk of harm, not an accident.⁵

Together, Castleman and Voisine mean that nearly any domestic assault conviction involving physical contact or bodily injury can trigger the federal firearm ban, whether the defendant acted intentionally, knowingly, or recklessly.

What the Government Has to Prove

A qualifying prior conviction is only part of the case. In Rehaif v. United States (2019), the Supreme Court held that the government must also prove the defendant knew they possessed a firearm and knew they belonged to a category of people barred from having one.⁶ Prosecutors often prove that knowledge with circumstantial evidence, such as prior warnings from law enforcement or acknowledgments signed at the original sentencing.

Penalties for Possessing a Firearm After a Qualifying Conviction

Under 18 U.S.C. § 924(a)(8), a knowing violation of § 922(g) carries up to 15 years in federal prison, a fine, or both.⁷ The 2022 Bipartisan Safer Communities Act raised the ceiling from 10 years. Actual sentences turn on criminal history, whether the firearm was used in another offense, and federal sentencing guidelines.

Getting Firearm Rights Back

The federal ban is not always permanent, though the routes to restoration are narrow. Under 18 U.S.C. § 921(a)(33)(B)(ii), a person is no longer considered convicted for purposes of the prohibition if the conviction has been expunged, set aside, or pardoned, or if civil rights have been restored under the applicable state’s law.⁸ There is a catch: if the expungement, pardon, or restoration specifically bars firearm possession, the federal ban stays in place.

For dating-partner convictions, the 2022 law added a separate path. A person with no more than one qualifying dating-relationship conviction regains firearm rights automatically five years after either the judgment of conviction or the completion of any custodial or supervised sentence, whichever is later. That restoration applies only if the person has not picked up another domestic violence conviction or other disqualifying offense during those five years.⁸ This time-based restoration does not extend to convictions involving spouses, former spouses, co-parents, or cohabitants. For those relationships, only expungement, a pardon, or a court order restoring civil rights will do.

Second Amendment Challenges After Rahimi

Defendants have repeatedly argued that § 922(g) violates the Second Amendment. In United States v. Rahimi (2024), the Supreme Court upheld the disarming of individuals a court has found pose a credible threat to the physical safety of another, calling that consistent with the Second Amendment.⁹

Rahimi involved § 922(g)(8), which covers people subject to domestic violence restraining orders rather than misdemeanants. But its reasoning matters for conviction-based prohibitions too. The majority grounded the decision in the historical tradition of American firearm regulation, pointing to founding-era “surety” and “going armed” laws that authorized disarming those who posed a clear threat of violence. A modern regulation does not need a historical twin; it needs to be “relevantly similar” in justification and burden.⁹ For anyone hoping to unwind the Castleman framework on constitutional grounds, Rahimi makes that a steep climb.
