Appeals Court Reads Knowledge Requirement Into Loaded-Firearm-While-Intoxicated Statute: Commonwealth v. Jackson (AC 25-P-933, October 16, 2026)

A licensed gun owner stopped for erratic driving at 4 a.m. on Interstate 291 was carrying a loaded .45 caliber pistol on his hip. The State trooper smelled alcohol, saw bloodshot eyes, watched the driver fumble through the glove box and fail field sobriety tests. The driver admitted to two beers. He was arrested for OUI and for violating G. L. c. 269, § 10H, which makes it a crime to carry a loaded firearm while intoxicated. A jury convicted him on both counts. The Appeals Court today reverses the firearms conviction but affirms the OUI. The reason: § 10H requires proof that the defendant knew the gun was loaded, and the Commonwealth’s evidence was too thin.

The Facts

On a March morning in 2021, a State police trooper traveling on I-291 in Springfield saw a white minivan ahead of him. Its taillights were off. The minivan drifted back and forth across the right lane, crossing repeatedly into the left lane and the breakdown lane. The trooper stopped it. Orette Nicholas Jackson was driving.

The signs of intoxication were unambiguous. The trooper smelled a strong odor of alcohol on Jackson’s breath. Jackson’s speech was slurred. His eyes were glazed, glassy, and bloodshot. When asked for his license and registration, Jackson fumbled through the glove box, dropping items on his lap and on the floor. He eventually produced the documents. At first he denied drinking, then said he had consumed two beers while visiting a friend.

The trooper ran Jackson’s information through the database in his cruiser. He learned that Jackson held a valid Massachusetts license to carry firearms. The trooper asked if Jackson was carrying a firearm. Jackson said he had one in a holster on his hip and allowed the trooper to take it. The firearm had a full magazine inserted. The trooper collected a second magazine from the glove box.

The parties later stipulated that the weapon was a .45 caliber Smith and Wesson semiautomatic pistol and that the cartridges met the statutory definition of ammunition. It would not have been possible by simple visual inspection of the exterior of the firearm to determine whether it was loaded.

The trooper directed Jackson to walk to the front of the minivan. Jackson seemed off balance and had to raise his arms for balance. He could not complete the field sobriety tests because he could not remember or follow the instructions and could not maintain his balance. The trooper formed the opinion that Jackson was intoxicated and arrested him for violating § 10H and for OUI. At times during booking, Jackson appeared to be asleep.

The Trial Court Ruling

At the beginning of the jury trial, the judge instructed the jury that the elements of carrying a loaded firearm while intoxicated were: first, that Jackson carried a firearm; second, that the firearm was loaded; and third, that he was under the influence. These instructions tracked the model jury instructions. At the close of the Commonwealth’s case, however, the judge sua sponte raised the question whether § 10H also required proof that Jackson knew the firearm was loaded.

After hearing argument, the judge ruled that knowledge was required. He cited Commonwealth v. Grayson, 96 Mass. App. Ct. 748 (2019), and noted the similarities between the language of the statute at issue in that case (G. L. c. 269, § 10 [n]) and that of § 10H. The Commonwealth objected. The judge then instructed the jury that the Commonwealth was required to prove, as an element of § 10H, that Jackson knew the firearm was loaded.

The jury convicted Jackson on both charges. This appeal followed.

What the Court Held

The Appeals Court holds that § 10H implicitly requires proof that the defendant knew the firearm was loaded. The statute does not explicitly state this requirement, but the court infers it from the statute’s structure, the severity of the penalties, and longstanding principles of Massachusetts criminal law.

The court’s analysis begins with Commonwealth v. Jackson, 369 Mass. 904 (1976), a Supreme Judicial Court decision involving G. L. c. 269, § 10 (a), which at the time did not explicitly require proof that the defendant knew he was carrying a firearm. The SJC, “mindful of . . . the need to avoid possible constitutional doubts,” interpreted § 10 (a) as requiring proof that the accused knew he was carrying a firearm. The court explained, “We would not feel justified in ruling that knowledge is not necessary where the penalty is so severe.”

The Legislature later amended § 10 (a) to include an explicit requirement that violators “knowingly” possess a firearm. Since then, the SJC has ruled that another provision of G. L. c. 269, § 10, implicitly requires knowledge of possession despite the absence of an explicit mens rea requirement. See Commonwealth v. O’Connell, 432 Mass. 657, 663 (2000).

Public Welfare Statute?

The Commonwealth argued that § 10H is a strict liability public welfare statute. Public welfare statutes are exceptions to the general presumption that criminal liability requires some level of mens rea. They typically criminalize conduct that is potentially harmful or injurious, even if it has not necessarily caused harm.

The Appeals Court rejects this argument. While § 10H prohibits risky behavior (carrying a loaded firearm while intoxicated), and while a licensee could avoid violating the statute by not carrying any firearm when intoxicated, the severity of the penalties distinguishes § 10H from public welfare offenses. The maximum penalties are two and one-half years’ imprisonment and a $5,000 fine. Public welfare offenses typically involve, as the U.S. Supreme Court put it in Staples v. United States, 511 U.S. 600, 616 (1994), “fines or short jail sentences.” Massachusetts courts have consistently interpreted statutes that provide harsh penalties but contain no specific mens rea requirement to contain an implicit requirement of mens rea.

The court also rejects the Commonwealth’s claim that requiring proof of voluntary intoxication satisfies due process concerns. The court offers a hypothetical: a licensee goes to dinner with a friend who is unknowingly carrying a loaded firearm in her bag. The licensee drinks enough to be under the influence. As they prepare to leave, the friend asks the licensee to hold her bag while she goes to the restroom. If the licensee takes the bag, he would be subject to prosecution under the Commonwealth’s theory, despite being unaware of the loaded firearm. The fact that the licensee is voluntarily intoxicated does not bear on his knowledge that he is carrying a firearm or that it is loaded.

Insufficient Evidence

Having determined that § 10H requires proof of knowledge, the court turns to the sufficiency of the evidence. The standard is whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. The Commonwealth need not introduce direct evidence of knowledge because proof may be based on reasonable inferences drawn from the evidence, provided the inferences are “reasonable and possible.”

The court compares this case to Commonwealth v. Resende, 94 Mass. App. Ct. 194 (2018), where there was also no direct evidence that the defendant knew the firearm he was carrying was loaded. In Resende, however, the defendant admitted to “some familiarity with firearms,” had been threatening someone and mentioning a gun immediately before being found with the firearm, and a police officer had to forcibly disarm him. The court characterized the question as “close” but concluded the evidence was sufficient.

The evidence in this case was less substantial. The jury could have drawn some inference of knowledge from Jackson’s carrying the firearm on his hip and the presence of a loaded magazine in the glove box. But there was no evidence comparable to the threats or admitted familiarity with firearms in Resende to suggest that Jackson actually had that knowledge. The court held in Grayson, 96 Mass. App. Ct. at 753-754, that the mere fact that a firearm was carried in a waistband was insufficient to prove knowledge that it was loaded. Here, there is little reason to think that the presence of ammunition in the closed glove box provided Jackson with knowledge that the firearm in the holster on his hip was loaded. The evidence was “too thin to prove knowledge beyond a reasonable doubt.”

The OUI Conviction Stands

Jackson argued that reversing his § 10H conviction requires vacating his OUI conviction as well. The court is not persuaded. The evidence supporting the OUI conviction was more than sufficient, a point Jackson does not contest. His argument that the jury might have viewed him unfavorably based on evidence that he was carrying a loaded firearm is speculative. The full circumstances of the stop would have been admissible in any event. The court sees no reason to disturb the guilty verdict on the OUI charge.

Why It Matters

This decision clarifies that § 10H is not a strict liability offense. The Commonwealth must prove not only that a defendant was carrying a loaded firearm while intoxicated, but that the defendant knew the firearm was loaded. The holding rests on the severity of the potential punishment (up to two and one-half years in prison and a $5,000 fine) and the principle that Massachusetts courts infer mens rea requirements to avoid constitutional doubts and ensure that criminal liability is not imposed without proof of culpable mental state.

The decision leaves open the question whether the defendant’s licensure is an element of the crime or merely expresses the Legislature’s intent to prevent a defendant from being convicted of violating both § 10 (n) (carrying a loaded firearm without a license) and § 10H for the same act. The court does not reach this issue because the parties did not brief it.

The court also declines to address Jackson’s facial challenge to the constitutionality of § 10H in light of New York State Rifle & Pistol Ass’n v. Bruen, 597 U.S. 1 (2022), given the reversal on sufficiency grounds. The court notes that during the pendency of the appeal, the U.S. Supreme Court decided United States v. Hemani, 608 U.S. 772, 794-795 (2026), finding unconstitutional a statute that prohibited a habitual marijuana user from possessing a firearm, but the Court in Hemani did “not address efforts to ban . . . those presently intoxicated . . . from possessing a firearm.”
