RICHMOND, Va. (March 13, 2024) – Today, Firearms Policy Coalition (FPC) announced that it has filed a supplemental brief with the Fourth Circuit Court of Appeals in its Bianchi v. Brown lawsuit, which challenges Maryland’s ban on so-called “assault weapons.” The brief, which is the final one before en banc oral arguments on March 20th, can be viewed at

“In this case, which involves a ban on common semiautomatic firearms, the textual question is straightforward,” argues the brief. “As the Supreme Court has held, as a plain text matter, ‘arms’ at a minimum includes all firearms, and there is no dispute that the semiautomatic firearms Maryland bans are firearms.The burden therefore falls to the State to demonstrate a tradition of regulation that would support its ban.”

“Maryland doesn’t have the power to ban its residents from owning these constitutionally protected arms–full stop,” said Cody J. Wisniewski, FPC Action Foundation’s Vice President and General Counsel, and counsel for FPC. “While this case is pending before the Supreme Court, the case also proceeds at the Fourth Circuit; and this brief highlights the errors of Maryland’s representation of Supreme Court precedent. While we remain resolute that the Fourth Circuit must apply the correct test, it is clear that now is the time for the Supreme Court to step in and head off the latest attempt of states to circumvent its precedent.” 

FPC is joined in the litigation by three FPC members, a Maryland firearms retailer, the Second Amendment Foundation, and the Citizens Committee for the Right to Keep and Bear Arms.
