The U.S. Supreme Court has announced it will hear two pivotal cases this fall involving bans on assault-style rifles, a move that could significantly reshape Second Amendment jurisprudence. The cases challenge laws in Cook County, Illinois, and Connecticut that prohibit possession of AR-15-type rifles, weapons frequently used in mass shootings and at the center of intense national debate.
The key legal question before the court is whether such firearms qualify as “dangerous and unusual,” a constitutional standard derived from previous rulings that has proved difficult for lower courts to consistently apply. The concept stems from the Supreme Court’s 2008 decision in District of Columbia v. Heller, which affirmed an individual’s right to possess firearms for self-defense, and its 2022 decision in New York State Rifle & Pistol Association v. Bruen, which extended this right to carrying guns in public.
In these latest cases, government attorneys point to numerous mass shootings involving AR-15-type rifles, arguing these weapons pose a clear danger and are uncommon in lawful civilian use. Conversely, gun rights advocates contend that the AR-15 has become one of the most widely owned rifles in the United States, suggesting that its popularity exempts it from being categorized as unusual or outside constitutional protection.
Lower courts have struggled with the standard established in Heller and Bruen, which requires judges first to determine if a weapon is in “common use.” If a firearm is common, any restriction must then align with historical precedent. This two-step test has generated confusion and inconsistency, with some courts upholding bans on semiautomatic rifles and large-capacity magazines, while others have struck them down.
Critics of the test highlight its circular logic; weapons banned early in U.S. history, such as fully automatic machine guns, are excluded from Second Amendment protections because historical laws prevented their widespread civilian availability. This raises questions about whether popularity should be the measure of constitutional rights.
Additionally, debates have emerged over the data used to demonstrate the prevalence of AR-15-type rifles. Some studies introduced by pro-gun parties face scrutiny, including allegations of biased methodology and undisclosed connections to gun advocacy groups.
Legal experts suggest the Supreme Court may reconsider the foundational basis for the “common use” doctrine, which traces back to a 1939 case concerning sawed-off shotguns and was only broadly applied in 2008. Some observers argue that this standard lacks clear textual or historical grounding in the Second Amendment itself.
The Court’s conservative majority appears poised to protect gun ownership rights, with Justices Samuel Alito, Neil Gorsuch, Brett Kavanaugh, and Clarence Thomas having a consistent record in favor of gun rights. Justice Kavanaugh has previously indicated skepticism toward assault weapons bans, noting the prevalence of AR-15s among law-abiding citizens in states permitting their ownership.
A decision is expected by next summer, marking roughly two decades since the landmark Heller ruling. The outcome will likely have far-reaching consequences in the ongoing national conversation over gun control and constitutional rights.
