In brief
Overview
According to Helaman Hansen, united States v. Hansen concerned the meaning of clause (iv) of a criminal statute that makes it illegal to encourage or induce non‑citizens to reside in the United States unlawfully.
The Court held that the terms “encourages” and “induces” are to be read in their specialized criminal‑law sense, limiting the statute to speech that is integral to unlawful conduct.
Background and question before the Court
Hansen moved to dismiss the clause (iv) charges on First Amendment overbreadth grounds.
Justice Thomas asked whether the statute had ever been applied in the way the Ninth Circuit hypothesized.
According to Justice Sotomayor, justice Sotomayor questioned how the Court could strike down one part of the statute while preserving another.
What each side argues
Helaman Hansen
According to Helaman Hansen, Hansen argues that clause (iv) punishes so much protected speech that it cannot be applied to anyone, including himself.
According to Helaman Hansen, he contends that clause (iv) uses “encourages” and “induces” in their ordinary sense, not a specialized criminal meaning.
According to Hansen, he further argues that the ordinary meanings include aiding and abetting, so the statute would prohibit even an op‑ed criticizing immigration if the audience includes undocumented persons.

Ms. Bhandari (Respondent’s Counsel)
Ms. Bhandari argues that Hansen should prevail, the government concedes the statute is unconstitutional under its plain meaning, and asks the Court to rewrite it to prohibit only solicitation and aiding‑and‑abetting.
Hansen’s Amici
According to Hansen's amici, Hansen’s amici describe a recent congressional letter to religious organizations urging them to preserve documents related to alleged encouragement of unlawful settlement.
What happened at oral argument
Justice Thomas asked whether the statute had ever been applied in the way the Ninth Circuit hypothesized.
According to Justice Sotomayor, justice Sotomayor questioned how the Court could strike down one part of the statute while preserving another.
Justice Kagan asked how this case differs from others involving similar statutory language.
Justice Alito raised hypothetical scenarios about encouraging prostitution and encouraging suicide, asking whether such speech would be subject to strict scrutiny.
Justice Sotomayor later asked where the line should be drawn regarding criminalizing civil violations.
What the Court decided
The Court held that clause (iv) uses “encourages or induces” in its specialized, criminal‑law sense, incorporating common‑law liability for solicitation and facilitation.
The Court further held that to the extent clause (iv) reaches any speech, it stretches no further than speech integral to unlawful conduct.
Justice Thomas (concurring) warned that the facial overbreadth doctrine allows courts to strike down laws in the abstract without any concrete application.
Justice Jackson (dissenting) emphasized that the statute’s purpose is to prohibit encouragement or inducement of non‑citizens to unlawfully enter, remain, or reside in the United States.
According to Justice Jackson (dissenting), Congress's removal of “willfully or knowingly” in the 1986 amendments did not change the mens‑rea required to violate this statute.
According to Justice Jackson (dissenting), the 1986 amendment added “reside” to the prohibited conduct.
According to Justice Jackson (dissenting), aiding‑and‑abetting liability is a centuries‑old principle allowing responsibility for crimes one did not personally commit.
According to Justice Jackson (dissenting), punishment for the encouragement provision is not tied to the punishment for the underlying offense.
According to Justice Jackson (dissenting), the majority has mounted a serious invasion of the legislative domain.
According to Justice Jackson (dissenting), the majority downplays the encouragement provision's threat to free expression by highlighting that Hansen fails to identify a single prosecution for protected expression in the 70 years since Congress enacted clause (iv)'s predecessor.
According to Justice Jackson (dissenting), the Government now seeks to read into the statute the very element it previously opposed as a textual limitation.
