Kungys v. United States

Background

Juozas Kungys is a naturalized citizen who obtained a visa in 1947 and became a U.S. citizen in 1954. In 1982 the United States filed suit to revoke his citizenship, alleging three grounds: participation in wartime killings, false statements on visa and naturalization forms about birth and wartime activities, and lack of good moral character because of false testimony. The District Court found misrepresentations but held them not material and rejected denaturalization; the Third Circuit reversed on the materiality of the birth statements and sustained the district court on the good‑character theory. The Supreme Court granted review and heard reargument.

Reasoning

The Court addressed what “material” means in the denaturalization statute and whether the false‑testimony provision requires materiality. It held a misrepresentation is material if it had a natural tendency to influence Immigration and Naturalization Service decisions, that materiality under §1451(a) is a question of law for judges, and that the government must prove materiality by clear, unequivocal, and convincing evidence. The Court also held §1101(f)(6) — which deems a person lacking good moral character if he gave false testimony to obtain immigration benefits — does not include a materiality requirement. Because factual questions remain (for example whether certain statements count as testimony and whether they were made with intent), the Court reversed the Third Circuit and remanded for further proceedings.

Real world impact

The ruling changes how courts evaluate old naturalization cases. It narrows one path to revoking citizenship by requiring proof that a lie would predictably influence an immigration decision, while leaving open denaturalization when a person knowingly gave false testimony under oath to obtain benefits. The decision is not final here: lower courts must reexamine other alleged misrepresentations and the factual questions left for the trier of fact.

Dissents or concurrances

Several Justices wrote separately. Justice Brennan joined the judgment but said the government must produce evidence supporting a fair inference that a disqualifying fact existed before a presumption arises. Justice Stevens (joined by Justices Marshall and Blackmun) would require proof of an actual disqualifying fact and criticized burden‑shifting. Justices O’Connor and White viewed the misrepresentations as material and favored affirmance; Justice White also urged definitive resolution of the Soviet depositions' admissibility.
