Bruen held that New York's proper-cause requirement violated the Second and Fourteenth Amendments. The Court said the government must justify modern firearm regulations by showing consistency with the Nation's historical tradition of firearm regulation. The ruling expanded public-carry rights and transformed lower-court review of gun laws.
Before Bruen, several states used may-issue licensing rules requiring applicants to show special need before carrying handguns in public. The Court had previously recognized an individual right to possess handguns in the home in Heller and incorporated that right against the states in McDonald.
Does New York's requirement that applicants show proper cause to obtain a public carry license violate the Second and Fourteenth Amendments?
The Second and Fourteenth Amendments protect an individual's right to carry a handgun for self-defense outside the home, and New York's proper-cause requirement for public carry licenses is unconstitutional.
How the justices lined up in this decision.
Bruen made it much harder for states to defend discretionary may-issue public-carry licensing systems. It also reshaped gun litigation by requiring courts to compare modern laws to historical analogues. That test has affected challenges to sensitive-place laws, domestic-violence firearm bans, age limits, assault-weapon rules, and many other regulations.
Justice Thomas wrote the Court's opinion, joined by Chief Justice Roberts and Justices Alito, Gorsuch, Kavanaugh, and Barrett. Justices Alito, Kavanaugh, and Barrett concurred. Justice Breyer dissented, joined by Justices Sotomayor and Kagan.
