Case Summary

Disposition

Affirmed

The First Circuit affirmed Moreno Vizcaíno-Peguero’s conviction under 18 U.S.C. § 922(g)(5)(A) for possessing a firearm while unlawfully present in the United States. Assuming without deciding that unlawfully present aliens are protected by the Second Amendment, the court held that the statute is nevertheless constitutional because it fits within the Nation’s historical tradition of disarming persons lacking allegiance to the sovereign.

Legal Issue

Whether the phrase “the people” in the Second Amendment includes aliens who are illegally or unlawfully present in the United States for purposes of Bruen’s step-one inquiry.

Circuit Positions

Circuit 4Circuit 5Circuit 8

Unlawfully present aliens are not part of “the people” and thus have no Second Amendment protection.

Circuit 1(this circuit)Circuit 2Circuit 6Circuit 7Circuit 9Circuit 10Circuit 11

Unlawfully present aliens are (or are assumed to be) part of “the people”; courts proceed to Bruen’s second step.

Conflict Summary

The Fourth, Fifth, and Eighth Circuits hold that unlawfully present aliens are outside the scope of “the people” protected by the Second Amendment, while several other circuits — including the First Circuit in this opinion — either hold or assume that such aliens are within that class and therefore analyze § 922(g)(5)(A) under Bruen’s historical-tradition step.
