One of the respondents, the Firearms Policy Coalition of gun confiscations, also provided a comment.

“We’re deeply disappointed that the court pressed pause on our defeat of ATF’s rule effectively redefining ‘firearm’ and ‘frame or receiver’ under federal law,” Cody Wisniewski, the group’s general counsel, said in an emailed statement.

“Regardless of today’s decision, we’re still confident that we will yet again defeat ATF and its unlawful rule at the Fifth Circuit when that court has the opportunity to review the full merits of our case.”

Oral arguments in the case are scheduled for Sept. 7 before the 5th Circuit in New Orleans. The case is known in that forum as VanDerStok v. Garland, court file number 23-10718.
