Supreme Court upholds Illinois assault weapons ban.

The U.S. Supreme Court has declined to block a ban on assault-style rifles and large capacity magazines enacted in Illinois after a deadly mass shooting in Chicago's Highland Park suburb in 2022. The court denied a request by the National Association for Gun Rights and a firearms retailer for an injunction blocking enforcement of the state law and a similar ban enacted by another Chicago suburb, Naperville, while a legal challenge to the measures proceeds. The law exempts existing owners, giving them a deadline of Jan. 1, 2024, to register their assault weapons with state police.
