King Belin v. United States

Whether 18 U.S.C. § 922(g)(1) is unconstitutional as applied to a defendant whose prior conviction is not accompanied by any judicial finding that he poses a present danger to the physical safety of others, where the Government does not prove that permanently disarming such individuals is consistent with the Nation’s historical tradition of firearm regulation.

Whether a defendant preserves an as-applied constitutional challenge to § 922(g)(1) for appellate review by filing and litigating a pretrial motion to dismiss the indictment on Second Amendment grounds, or whether a court of appeals may treat the claim as forfeited and apply plain-error review.
