The Supreme Court just announced that it will consider this issue, in U.S. v. Rahimi; this is unsurprising, since the Court is generally inclined to review cases where a court held that a federal statute was unconstitutional, and where the federal government asks for review. Here's my post from February, when the Fifth Circuit decided the case (see also Stephen Halbrook's post after the denial of en banc rehearing, where he noted that Supreme Court review was likely):
From U.S. v. Rahimi, decided today by the Fifth Circuit, in an opinion by Judge Cory Wilson, joined by Judges Edith Jones and James Ho:
The question presented in this case is not whether prohibiting the possession of firearms by someone subject to a domestic violence restraining order is a laudable policy goal. The question is whether 18 U.S.C. § 922(g)(8), a specific statute that does so, is constitutional under the Second Amendment of the United States Constitution. In the light of N.Y. State Rifle & Pistol Ass'n, Inc. v. Bruen (2022), it is not.
