A U.S. federal judge overturned California's 32-year-old ban on assault weapons on Friday, describing it as a "failed experiment" and prompting scathing criticism from the state's governor and attorney general.

California has prohibited the sale of assault weapons since 1989. The ban was challenged in a 2019 lawsuit against California's attorney general by plaintiffs including James Miller, a state resident, and the San Diego County Gun Owners, a political action committee.

"This case is about what should be a muscular constitutional right and whether a state can force a gun policy choice that impinges on that right with a 30-year-old failed experiment," judge Roger Benitez of the U.S. District Court for the Southern District of California wrote in the court order filed late on Friday.
