In HEMANI, the U.S. Supreme Court refined the methodology lower courts should use in Second Amendment cases after Bruen. The opinion arose from a challenge to 18 U.S.C. § 922(g)(3), a federal firearm prohibition, and its reasoning has broader implications for how courts assess the historical and legal basis for gun restrictions. The ruling is notable less for public opinion or legislation than for shaping the doctrinal framework that will govern future firearms cases.
