In the 1960 Supreme Court case Chaunt v. United States, the court ruled in favor of Joseph Chaunt, a naturalized U.S. citizen who was facing denaturalization due to alleged misrepresentations during his citizenship application process. The government claimed that he had failed to disclose past arrests and membership in the Communist Party on his application form. However, Mr. Chaunt argued that these omissions were not material or relevant to his eligibility for citizenship. The Supreme Court agreed with Mr. Chaunt's argument and held that false statements made by an applicant for citizenship are grounds for revocation only if they can be proven as materially affecting the decision-making process of immigration officials at the time of granting citizenship. This ruling set a precedent regarding denaturalization cases: it established that minor falsehoods or omissions on an individual’s naturalization paperwork do not automatically warrant stripping them off their acquired U.S Citizenship unless such lies significantly influenced their approval for naturalization.

In the dissenting opinion for Chaunt v. United States, Justice Frankfurter disagreed with the majority's ruling that a naturalized citizen could only be denaturalized if their misrepresentation or concealment of facts was material to gaining citizenship. He argued that this interpretation was not supported by the language of Section 340(a) of the Immigration and Nationality Act, which states that an individual can be stripped of their citizenship for "willfully" providing false information during their naturalization process, regardless of its relevance to obtaining citizenship. According to him, any deliberate deception should be grounds for revocation because it undermines trust in the system and disrespects U.S law. Furthermore, he believed that Congress intended this provision as a deterrent against dishonesty during immigration proceedings rather than just preventing ineligible individuals from becoming citizens.
