Background

Nestor Jose Mendoza-Garcia was convicted in the U.S. District Court for the Western District of Texas of violating 18 U.S.C. § 922(g)(5), which prohibits illegal aliens from possessing firearms. Mendoza-Garcia appealed his conviction to the Fifth Circuit, arguing that the statute is unconstitutional as applied to him under the Second Amendment and that it exceeds Congress’s power under the Commerce Clause.

The Government moved for summary affirmance, contending that prior Fifth Circuit precedent directly foreclosed Mendoza-Garcia’s constitutional challenges. Mendoza-Garcia conceded that his claims were foreclosed by binding authority but sought to preserve them for further appellate review.

The Court’s Holding

The Fifth Circuit granted the Government’s motion for summary affirmance and affirmed Mendoza-Garcia’s conviction. The court relied on United States v. Medina-Cantu, 113 F.4th 537 (5th Cir. 2024), cert. denied, 145 S. Ct. 1318 (2025), which had previously upheld § 922(g)(5) against both Second Amendment and Commerce Clause challenges.

The court applied the summary affirmance procedure, finding that there was no substantial question as to the outcome of the case. Under this streamlined appellate standard, the court did not issue a detailed opinion addressing Mendoza-Garcia’s arguments, instead relying entirely on the binding precedent established in Medina-Cantu. The Government’s alternative motion for an extension of time to file a full appellate brief was denied as moot.

Key Takeaways

  • The Fifth Circuit reaffirms that § 922(g)(5) is constitutional under the Second Amendment and does not violate the Commerce Clause.
  • Illegal aliens do not retain Second Amendment rights that prevent federal firearm possession restrictions.
  • Prior Fifth Circuit precedent in Medina-Cantu conclusively forecloses constitutional challenges to this statute in the Fifth Circuit.
  • Summary affirmance was appropriate because the controlling precedent made the legal outcome clear and certain.

Why It Matters

This decision reinforces that the Fifth Circuit has established firm precedent rejecting Second Amendment and Commerce Clause defenses to federal firearm possession restrictions for illegal aliens. Prosecutors in the Fifth Circuit can confidently proceed with § 922(g)(5) charges without anticipating successful constitutional defenses at the appellate level.

The reliance on summary affirmance and Medina-Cantu suggests that similar appeals challenging the statute’s constitutionality will likely meet the same fate without requiring full appellate briefing and oral argument, streamlining appellate resolution in these cases.
