Key Facts

• The Supreme Court struck down Hawai'i’s law banning guns in private businesses open to the public by a 6-3 vote.
• The court said states cannot force all private businesses open to the public to be gun-free; business owners must decide instead.
• States can still ban guns on private property that is not open to the public, like homes or offices.
• Some states are requiring businesses to post signs about whether guns are allowed or banned.
• The court often allows gun bans in "sensitive places" like schools, government buildings, parks, bars, and restaurants serving alcohol.
• Illinois’ ban on assault-style weapons and high-capacity magazines was upheld by a federal court based on their military use.
• Individuals deemed dangerous, such as convicted felons or those committed for mental health reasons, can be blocked from buying guns, a point the Supreme Court confirmed in 2024.
• The court’s approach relies heavily on historical gun laws, which limits modern lawmakers’ ability to create new gun safety rules.
