In Hughes v. United States (1951), the Supreme Court ruled that a federal court has jurisdiction to hear a case involving an alleged violation of state law if the defendant is charged with conspiracy to defraud the United States, even if no actual fraud occurred. The case involved two men who were convicted for conspiring to submit false statements about their employment status in order to receive unemployment benefits from the Railroad Retirement Board, which they did not actually receive. They argued that since they had not received any money or property as a result of their actions, there was no crime under federal law and therefore no jurisdiction for a federal court. However, the Supreme Court disagreed and upheld their convictions on appeal.

In the dissenting opinion for Hughes v. United States, Justice Minton argued that the majority's decision to uphold Hughes' conviction was incorrect because it failed to consider whether or not his confession had been coerced by law enforcement officers. He believed that there were significant indications of coercion in this case, including prolonged questioning and a lack of legal counsel during interrogation. Furthermore, he contended that any evidence obtained through such coercive means should be deemed inadmissible in court as per the Fifth Amendment's protection against self-incrimination. Therefore, he felt strongly that Hughes' conviction should have been overturned due to these violations of his constitutional rights.
