NEW ORLEANS, LA (August 24, 2023) – Today, Firearms Policy Coalition (FPC) and FPC Action Foundation (FPCAF) announced the filing of their response brief with the Fifth Circuit Court of Appeals in VanDerStok v. Garland, defending their win at the district court in their lawsuit challenging the ATF’s “Frame or Receiver” Rule. The brief can be viewed at

“The district court correctly held that the Bureau of Alcohol, Tobacco, Firearms, and Explosives (‘ATF’) exceeded its authority by seeking to extend the definition of ‘firearm’ and ‘frame or receiver’ in federal law beyond what Congress has permitted,” argues the brief. “The district court also correctly held that vacatur was the proper remedy when a federal agency has been found to exceed its statutory authority. This Court, which has already found that Plaintiffs are likely to succeed on the merits in showing the challenged rule is unlawful, should affirm the district court’s decision.”

“ATF violated federal law and exceeded its congressionally limited authority when it promulgated the ‘Frame or Receiver’ Rule that purports to grant it near-unlimited authority to regulate items that are not firearms as if they were,” said Cody J. Wisniewski, FPCAF’s General Counsel and Vice President of Legal, and FPC’s counsel in this case. “Through this rule, ATF effectively amended and expanded federal law, something the agency has no power to do. We look forward to the Fifth Circuit reaffirming our win and striking down ATF’s rule.”

Plaintiffs in this case are two individuals, Tactical Machining, LLC, and FPC. FPCAF represents the Plaintiffs, alongside Mountain States Legal Foundation.
