Corey Wilson was convicted following a bench trial in the United States District Court for the Northern District of Texas on two counts of possession of an unregistered machinegun. On appeal, Wilson challenged the sufficiency of the evidence supporting his conviction and argued that the federal statutory definition of a 'machinegun' was unconstitutionally vague. The case turned on whether the government proved Wilson knew the devices he possessed had the specific characteristics that brought them within the legal definition of a machinegun, and whether the statute provided fair notice to someone in his position.
The Fifth Circuit conducted a de novo but highly deferential review of the sufficiency of the evidence. Citing United States v. Cervantes, the court reiterated that the government was required to prove Wilson knew the devices he possessed had the characteristics that brought them within the statutory definition of a machinegun, a requirement established by the Supreme Court in Staples v. United States. The court found that Wilson's arguments merely suggested the district court should have viewed the evidence differently, but he failed to establish that any rational trier of fact would have found the evidence insufficient to convict. Regarding the vagueness challenge, the court applied the principle that a defendant cannot claim a statute is vague as applied to conduct they knowingly engaged in if they could not have known the device was a machinegun. Citing United States v. Uhlenbrock and United States v. Clark, the court noted that the government proved Wilson did have such knowledge. Because Wilson's conduct was clearly proscribed, he could not complain of the vagueness of the law as applied to the conduct of others.
The judgment of the district court is affirmed, meaning Wilson's convictions for possession of unregistered machineguns stand. The decision reinforces the Fifth Circuit's strict application of the knowledge requirement under Staples and limits the availability of vagueness challenges in machinegun cases where the defendant's knowledge of the device's characteristics is established. No remand instructions were issued as the court affirmed the lower court's judgment directly.
