Commonwealth v. Canjura
Annotate this Case
The case involves the defendant, David E. Canjura, who was arrested by Boston police officers on July 3, 2020, after an altercation with his girlfriend. During a search incident to the arrest, officers found a spring-assisted knife on Canjura. He was charged with carrying a dangerous weapon under G. L. c. 269, § 10 (b), and assault and battery on a family or household member. Canjura conceded the knife met the statutory definition of a switchblade but challenged the constitutionality of the statute under the Second Amendment.
In the Boston Municipal Court, Canjura filed a motion to dismiss the charge, arguing that the statute violated his Second Amendment rights. The judge denied the motion, and Canjura entered a conditional plea, reserving his right to appeal. The court accepted his plea and placed him on administrative probation, while the assault and battery charge was dismissed at the Commonwealth's request. Canjura appealed, and the Supreme Judicial Court of Massachusetts granted direct appellate review.
The Supreme Judicial Court of Massachusetts reviewed the case and applied the two-part test from New York State Rifle & Pistol Ass'n v. Bruen. The court first determined that switchblades are "arms" under the Second Amendment, as they fit historical definitions and were commonly used for lawful purposes at the time of the founding. The court then examined whether the statute was consistent with the nation's historical tradition of arms regulation. Finding no historical analogues to justify the regulation of switchblades, the court concluded that G. L. c. 269, § 10 (b), violated the Second Amendment. The court reversed the denial of Canjura's motion to dismiss, vacated his admission to sufficient facts, and ordered judgment to enter for the defendant on the dangerous weapon charge.
