Selected case law

Caetano v. Massachusetts, 577 US 411, 136 S. Ct. 1027(2016).
The US Supreme Court held that the reasoning of the SJC in Comm. v. Caetano, 470 Mass. 774 (2015), in ruling that the Second Amendment didn’t apply to stun guns was incorrect. The US Supreme Court sent the case back to Massachusetts. The case didn’t rule the Massachusetts law, MGL c. 140, § 131J, unconstitutional. 

Chardin v. Boston Police Commissioner, 465 Mass. 314 (2013). 
Massachusetts firearms licensing statute "does not infringe on a right protected by the Second Amendment" and involves a record of a felony as a delinquent child.

Chief of Police of Taunton v. Caras, 95 Mass. App. Ct. 182 (2019)
Discusses the standard of review when a court is asked to review a decision by the chief of police revoking a firearms license.

Comm. v. Buttimer, 482 Mass. 754 (2019)
A gun "need not be operational to prove either assault by means of a dangerous weapon or armed assault with intent to murder.  It is enough for assault by means of a dangerous weapon that the weapon appear dangerous to the victim of the assault; the weapon does not actually have to be operational."

Comm. v. Cassidy, 479 Mass. 527 (2018)
Large capacity. "[T]o sustain a conviction under G. L. c. 269, § 10 (m), the Commonwealth must prove that a defendant either knew the firearm or feeding device met the legal definition of "large capacity" or knew it was capable of holding more than ten rounds of ammunition." Provides a model jury instruction in the appendix.

Comm. v. Fettes, 64 Mass. App. Ct. 917 (2005)
A dog can be a dangerous weapon. "A dangerous weapon is 'any instrument or instrumentality so constructed or so used as to be likely to produce death or great bodily harm.' Commonwealth v. Farrell, 322 Mass. 606, 614-615 (1948). See also Anderson, Wharton's Criminal Law and Procedure, § 361. There can be little doubt that a dog . . . used for the purpose of intimidation or attack falls within this definition." 

Comm. v. Garcia, 82 Mass. App. Ct. 239 (2012)
Provides detailed definitions of "dirk knife" and "dagger."

Comm. vs. Garrett, 473 Mass. 257 (2015)   
“This court concluded that a BB gun is not a firearm for purposes of the armed robbery statute, G. L. c. 265, § 17”

Comm. v. McGowan, 464 Mass. 232 (2013)
Court held that "because [the gun storage law, G.L. c.140,] § 131L (a) is consistent with the right to bear arms in self-defense in one's home and is designed to prevent those who are not licensed to possess or carry firearms from gaining access to firearms, it falls outside the scope of the Second Amendment."

Comm. v. Rodriguez, 482 Mass. 366 (2019)
Lengthy discussion of mandatory minimum sentences in GL c.269, § 10. "This court concluded that a criminal defendant who has been convicted of possession of a large capacity feeding device, in violation of G. L. c. 269, § 10 (m), lawfully may be sentenced to State prison for not less than one year nor more than two and one-half years."

Comm. v. Runyan, 456 Mass. 230 (2010)
Trigger locks or locked containers can be required. The Second Amendment isn't incorporated under the Fourteenth Amendment's guarantee of substantive due process and therefore doesn't apply to the States. Further, the General Laws c. 140, § 131L (a) can be distinguished from the law ruled unconstitutional in Heller, because "an individual with a valid firearms identification card issued under G. L. c. 140, § 129C, is not obliged to secure or render inoperable a firearm while the individual carries it or while it remains otherwise under the individual's control...; the statute therefore does not make it impossible for those persons licensed to possess firearms to rely on them for lawful self-defense."

Comm v. Stephens, 67 Mass. App. Ct. 906 (2006)
A starter pistol that doesn’t have a barrel plug or obstruction in the cylinder that would stop a projectile from passing through the barrel is a firearm.

Comm. v. Veronneau, 90 Mass. App. Ct. 477 (2016)
"The judge's finding that the defendant was guilty of carrying a loaded firearm while under the influence of intoxicating liquor was not inconsistent with the judge's finding that the defendant was not guilty of operating a motor vehicle while under the influence of intoxicating liquor...A condition of probation requiring a criminal defendant to surrender his firearms during the term of his probation did not violate the defendant's constitutional right to bear arms."

District of Columbia v. Heller, 554 US 570 (2008)
"The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home."

Fletcher v. Haas, 851 F. Supp. 2d. 287 (2012)
"[T]he Massachusetts firearms regulatory regime as applied to [lawful permanent resident aliens], contravenes the Second Amendment." Judgment entered "enjoining denial of firearm licenses and permits to [plaintiffs] solely on the basis of their permanent resident alien status."

Goudreau v. Nikas, 98 Mass. App. Ct. 266 (2020)
G.L. c.140 § 131L applies to firearm dealers and guns kept in a commercial setting. Guns in a store must still be secured as the law requires.

McDonald v. City of Chicago, 561 US 742 (2010)
In clearly stating that "the Due Process Clause of the Fourteenth Amendment makes the Second Amendment right binding on the States," the court also reiterated its statement from Heller that "the right to keep and bear arms is not 'a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.'”

New York State Rifle & Pistol Ass'n, Inc. v. Bruen, __ U.S. __ (June 23, 2022)
Supreme Court held that New York's “proper cause” requirement for issuing a license to carry a firearm violates the Second and Fourteenth Amendments.

Phipps v. Boston Police Commissioner, 94 Mass. App. Ct. 725 (2019)
"A revoke the plaintiff's license to carry a firearm was arbitrary and capricious."  "Discussion of the standard of review of the decision to revoke a license to carry a firearm, of the standard to be used by a firearm licensing authority when determining whether to issue a firearm license with restrictions, and of the statutory scheme for firearm licensure."

Ramirez v. Commonwealth, 479 Mass. 331 (2018)
"This court concluded that stun guns are "arms" within the protection of the Second Amendment to the United States Constitution and that...barring all civilians from possessing or carrying stun guns, even in their home, was inconsistent with the Second Amendment and therefore unconstitutional."
