CHICAGO, IL (June 25, 2024)—Today, Firearms Policy Coalition announced the filing of its opening brief with the Seventh Circuit Court of Appeals in Viramontes v. Cook County, its Second Amendment lawsuit challenging the county’s ban on so-called “assault” weapons. Case documents in Viramontes can be found at

Citing both Supreme Court Justice Sotomayor and the ATF, FPC's brief drives home the indisputable fact that the Cook County semiautomatic firearms ban is unconstitutional. 

“As our brief makes clear, Cook County’s authoritarian ban on protected arms is totally unconstitutional,” said FPC President Brandon Combs. “We will continue to fight forward until this ban and all others like it are eliminated.”

This case joins many other FPC lawsuits challenging bans on common firearms as part of its high-impact FPC Law strategic litigation program to eliminate disarmament schemes and restore the rights of peaceable people.

FPC is joined in this litigation by two individual FPC members and the Second Amendment Foundation. FPC is represented by attorneys David H. Thompson, Peter A. Patterson, and William V. Bergstrom, as well as David G. Sigale.
