Case Summary

Disposition

Affirmed

The Eighth Circuit affirmed Richard Alan Kucera’s convictions for sex-trafficking minors and producing child pornography. The court upheld the denial of Kucera’s suppression motion, rejected challenges to jury instructions on §1591 and §2251(a), and held that neither the statute nor the Constitution requires the government to prove Kucera knew the victims’ ages or to allow a mistake-of-age defense.

Circuit Split Identified

Legal Issue

Whether 18 U.S.C. § 2251(a) requires (or the First Amendment mandates) recognition of an affirmative mistake-of-age defense/knowledge requirement regarding a victim’s minority in child-pornography-production prosecutions.

Circuit Positions

Circuit 8(this circuit)

No scienter or mistake-of-age defense required; §2251(a) imposes strict liability regarding the victim’s minority.

Circuit 9

First Amendment compels recognition of a reasonable mistake-of-age affirmative defense to §2251(a).

Conflict Summary

The Eighth Circuit treats §2251(a) as a strict-liability statute as to the victim’s age and expressly disallows any mistake-of-age defense, while the Ninth Circuit has held that the First Amendment requires courts to permit a reasonable mistake-of-age defense for §2251(a) offenses.
