Here are the materials in United States v. First:
An excerpt from the court’s syllabus:
Reversing the district court’s dismissal of an indictment charging the defendant as a misdemeanant in possession of a firearm in violation of 18 U.S.C. § 922(g)(9), the panel held that a misdemeanor conviction obtained in tribal court may qualify as a predicate offense to a § 922(g)(9) prosecution so long as the defendant was provided whatever right to counsel existed in the underlying misdemeanor proceeding.
The panel concluded that this result does not violate the Sixth Amendment, the Due Process Clause of the Fifth Amendment, or the Equal Protection Clause of the Fourteenth Amendment.
