In the case of Rogers, Attorney General, v. Quan et al., 1957, the U.S. Supreme Court dealt with issues related to immigration and nationality laws. The respondents were Chinese nationals who had been born in China but claimed American citizenship through their alleged father's status as a citizen by birthright. They sought admission into the United States based on this claim of citizenship despite lacking proper documentation proving their relationship to their supposed father due to circumstances surrounding World War II and subsequent civil unrest in China. The Immigration and Nationality Act required that such claims be supported by "clearly convincing evidence." However, it was argued that this standard was too high given the conditions at hand which made obtaining such proof difficult if not impossible for many individuals like them. The Supreme Court ruled against them stating that Congress has broad power over immigration matters including setting standards for proof of citizenship claims under these circumstances. It held that requiring "clearly convincing evidence" did not violate any constitutional rights or principles even considering the challenging conditions faced by those seeking to prove such relationships.

The dissenting opinion in the case of Rogers v. Quan argued that the majority's decision to uphold a state law requiring loyalty oaths from public employees was an infringement on First Amendment rights. The justice believed that such laws could be used as tools for political repression, stifling free speech and thought by forcing individuals to adhere to government-approved ideologies under threat of losing their livelihoods. They also expressed concern about the vagueness of these types of laws, which they felt left too much room for arbitrary enforcement and potential abuse. Furthermore, they disagreed with the majority's assertion that it was necessary or appropriate for courts to defer so heavily to legislative judgments in cases involving constitutional liberties.
