⚖ The Constitutional Angle
Caetano held the Second Amendment covers all bearable arms, including those not in existence at the founding, and that uncommon in 1789 does not equal unusual. Heller confirmed the right is individual but not unlimited. Whether semi-automatic rifles in common use are protected is the exact question the Court has now taken up in Viramontes and has not yet answered.
Jaime Caetano v. Massachusetts 577 U.S. 411 (2016)
Vote: Unanimous per curiam (8-member Court, post-Scalia); no recorded vote split · Opinion: Per curiam (unsigned)
Summarily vacating the SJC's judgment without briefing on the merits or oral argument, the Court held that each of the SJC's three rationales contradicted Heller: the Second Amendment extends prima facie to all bearable arms, including those not in existence at the founding; 'unusual' cannot be equated with 'not in common use in 1789'; and protection is not limited to weapons useful in warfare. The case was remanded for further proceedings; the Court did not itself hold the Massachusetts ban unconstitutional.
District of Columbia v. Heller 554 U.S. 570 (2008)
Vote: 5-4 · Opinion: Scalia
The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia and to use it for traditionally lawful purposes such as self-defense within the home. The right is not unlimited: the Court noted that longstanding prohibitions (e.g., possession by felons and the mentally ill, carrying in sensitive places, conditions on commercial sale) remain presumptively lawful. D.C.'s ban on handgun possession in the home and its requirement that lawful firearms in the home be kept nonfunctional violate the Second Amendment.
