8th Cir.

United States of America v. Stephen Biviano Zapata

June 18, 2026 ·25-2000 ·Panel Decision · By James Taylor

The Eighth Circuit affirmed a district court's denial of a motion to dismiss an indictment challenging the constitutionality of a federal firearm statute. The court held that the defendant's Second Amendment argument was foreclosed by binding circuit precedent.

Background

Stephen Biviano Zapata pled guilty to unlawful possession of a firearm as an unlawful user of a controlled substance in violation of Section eighteen United States Code Section nine hundred twenty-two subsection G three. The district court sentenced him to twenty-seven months in prison. Zapata appealed, arguing the statute was unconstitutional on its face under the Second Amendment.

The court’s reasoning

The court concluded that the district court properly denied the motion to dismiss. The court found that Zapata’s argument was foreclosed by circuit precedent, specifically United States versus Veasley. The court noted that the Supreme Court’s decision in United States versus Rahimi does not call into question this precedent.

What it means going forward

The ruling reinforces the binding authority of Eighth Circuit precedent regarding Second Amendment challenges to federal firearm statutes for unlawful users of controlled substances.
