CHICAGO, IL (May 1, 2023) – Less than a week after securing a preliminary injunction against Illinois’ ban on commonly owned semi automatic firearms and the magazines they utilize, Firearms Policy Coalition (FPC) announced that it has filed a motion for summary judgment in its Viramontes v. Cook County lawsuit, which challenges Cook County’s ban on so-called “assault weapons.” The motion can be viewed at

“Here, the Second Amendment’s plain text covers the firearms Cook County bans, so it falls to the County to justify the ban as consistent with historical tradition rooted in the Founding,” argues the motion. “They cannot possibly do so, because Bruen has already established that there is no tradition of banning commonly possessed arms.”

“Cook County’s ban on so-called ‘assault weapons’ is no more constitutional than the one enacted earlier this year by the State of Illinois,” said Richard Thomson, FPC's Vice President of Programs. “FPC looks forward to its litigation getting the county’s ban enjoined, just like it did for the state’s ban last week.”

FPC is joined in this lawsuit by the Second Amendment Foundation.
