Supreme Court will rule on semiautomatic rifle bans, with California's law in the balance

The justices consolidated challenges to Illinois and Connecticut AR-15 bans for argument this fall. The outcome will bear directly on California's Assault Weapons Control Act, and the Court is holding California's magazine-cap petition in the meantime.

Who this affects: California currently enforces a statewide restriction on firearms classified as assault weapons, which includes many semiautomatic rifles. If the Supreme Court issues a broad ruling striking down the Illinois and Connecticut laws, it could establish a precedent that invalidates California's similar regulations. A decision is expected sometime in 2027 following the fall 2026 oral arguments, at which point the legal status of semiautomatic rifles in California could change.

The biggest Second Amendment question in years is on the Supreme Court's calendar for this fall: whether state and local bans on semiautomatic rifles such as the AR-15 are constitutional.

On June 30, 2026, the United States Supreme Court announced it will review the constitutionality of prohibitions on semiautomatic rifles, SCOTUSblog reported. The justices consolidated two separate challenges, one from Illinois and another from Connecticut, with oral arguments anticipated for the fall of 2026.

The first dispute involves an Illinois resident challenging a Cook County ordinance. According to SCOTUSblog, Cutberto Viramontes initiated his lawsuit in 2021. Lower federal tribunals upheld the local restriction by relying on a 2023 appellate decision, which concluded that such firearms are not materially different from military weaponry. Cook County officials urged the justices to reject the petition, arguing that these rifles hinder law enforcement during mass shootings and lack evidence of use in lawful self-defense.

The second matter stems from a Connecticut statute enacted following the 2012 Sandy Hook Elementary School tragedy. Gun rights advocates and individual owners asked the high court to intervene after an appellate panel sustained the state restriction. The challengers argued that a ban contradicts prior judicial precedent, stating that "a firearm cannot be banned if it is in common use for lawful purposes." Conversely, Connecticut officials maintained that market saturation does not shield unusually dangerous weapons from state regulation.

In related actions on June 30, 2026, the justices declined to hear appeals concerning firearm restrictions for adults under 21 years old. Justice Clarence Thomas noted his dissent in one such case involving federal handgun sales. Additionally, SCOTUSblog noted that the court took no action on pending petitions regarding high-capacity magazine prohibitions.
