A federal judge ruled New York’s ban on civilian body armor violates the Second Amendment, rejecting state claims that protective gear falls outside the Constitution’s plain text.
United States District Judge John L. Sinatra Jr. held in a 47-page opinion that body armor is an “Arm” protected by the Second Amendment and that New York failed the historical-tradition test required for new gun-related restrictions.
The decision, described in Daily Caller reporting as coming Wednesday, grants the state a 14-day stay so Attorney General Letitia James can decide whether to appeal to the United States Court of Appeals for the Second Circuit.
New York had banned private ownership of body armor such as Kevlar vests after the May 2022 Buffalo supermarket shooting that left ten people dead. The state became the only one in the country to bar civilians outside a short list of authorized professions from possessing the gear.
The Firearms Policy Coalition sued James in July 2024 on behalf of three New York residents who wanted to buy body armor for personal protection. James’s office argued the Second Amendment did not cover body armor and that modern materials did not exist when the Bill of Rights was ratified.
Sinatra, a Trump appointee, dismissed those claims. He wrote that the plain text of the Second Amendment reaches body armor and that regulation is allowed only when the state shows consistency with the nation’s historical tradition of sufficiently analogous rules.
“Body armor is an ‘Arm’ protected by the plain text of the Second Amendment,”
the judge stated. He continued:
“As such, regulation in this area is permissible only if the State demonstrates that the new enactment is consistent with the Nation’s historical tradition of sufficiently analogous regulations. New York fails that test.”
Plaintiffs submitted market-based calculations showing more than 82,000 units of body armor purchased in 2023, more than 87,000 in 2024, and more than 93,000 in 2025. Sinatra treated that evidence, plus statements from amici, as proof the products are in common use for lawful purposes.
“Plaintiffs have adduced reliable evidence that body armor is in common use today,”
he wrote, adding that the court could reach the common-sense conclusion that the gear is used lawfully. The opinion noted that the other 49 states already let civilians buy body armor.
On the technology argument, Sinatra was direct.
“That Kevlar did not exist at the Founding does not alter the constitutional principles guiding the Court’s analysis,”
he said. He warned that accepting New York’s logic would treat many modern handguns as unusual and dangerous simply because they improve on 18th-century designs, the same approach the Supreme Court rejected in Heller and Bruen.
The final win did not appear overnight. Months earlier, Sinatra had already rejected a motion to dismiss from James and other New York officials and found the plaintiffs had standing to challenge the sales and possession limits, the Washington Examiner reported when the suit advanced toward trial.
That earlier order kept the constitutional fight open. The latest opinion closes the district-court chapter by striking the ban itself.
The Firearms Policy Coalition marked the result on X the day before the Daily Caller account, calling the law a “first-of-its-kind” ban and declaring a federal-court win under the Second Amendment.
For years New York treated civilian body armor as contraband while every other state left purchase and possession lawful for ordinary residents. The ban grew out of the Buffalo attack, yet the statute swept far beyond any shooter: it blocked peaceful people who simply wanted better odds of surviving an attack.
James’s office offered two main defenses, that body armor is not an “Arm,” and that modern materials post-date the Founding. Both failed. The court followed the Supreme Court’s text-and-history method rather than interest-balancing or public-safety slogans.
The 14-day stay gives Albany a short window to seek review in the Second Circuit. Until then the district ruling stands as a clear statement that protective gear worn by civilians is not beyond the Constitution’s reach.
Lawful residents who want to protect themselves should not need special permission from Albany to wear a vest. When a blue-state attorney general invents a unique ban and then loses on text, history, and common use, the failure belongs to the policy, not the people who challenged it.
