Caetano v. Massachusetts
Headline: Vacated Massachusetts decision limits state power to uphold stun-gun bans, finding the state court misapplied Second Amendment precedents and sending the case back for reconsideration affecting self-defense weapon rules.
Holding: The Court granted review, vacated the Massachusetts court’s judgment, and remanded because the state's reasons for excluding stun guns from Second Amendment protection contradicted Heller and McDonald.
- Makes it harder for states to categorically ban stun guns.
- Allows people convicted under stun-gun bans to seek new review.
- Creates room to challenge blanket prohibitions on modern self-defense weapons.
Summary
Background
Jaime Caetano is a woman who acquired a stun gun to protect herself from a violent ex-boyfriend. Police found the device during a shoplifting investigation, she was convicted under a Massachusetts law that bans electrical weapons, and the Massachusetts Supreme Judicial Court affirmed that conviction.
Reasoning
The central question was whether the Second Amendment protects possession of modern stun guns. The United States Supreme Court’s per curiam opinion explained that earlier cases (Heller and McDonald) treat the Second Amendment as extending to bearable arms even if those arms did not exist at the founding and apply the Amendment against the States. The Massachusetts court had said stun guns were unprotected because they were not in common use in 1789, were “dangerous and unusual,” and were not military weapons. The Supreme Court found those justifications inconsistent with its precedents, granted review, vacated the state court’s judgment, and sent the case back for further proceedings not inconsistent with this opinion.
Real world impact
The ruling prevents the Massachusetts court’s reasoning from being used to uphold a blanket stun-gun ban and allows renewed challenges to such bans under the Second Amendment. The Supreme Court’s decision does not itself resolve the final merits of the constitutional question; it requires the state court to reconsider the case in light of federal precedent. Individuals convicted under similar bans may get additional opportunities to challenge convictions.
Dissents or concurrances
Justice Alito, joined by Justice Thomas, wrote separately to emphasize Caetano’s facts and argued that Massachusetts’ categorical ban violates the Second Amendment because stun guns are widely owned and used for self-defense.
