In Weber v. United States, the Supreme Court ruled on a case involving an individual who was convicted of making false statements to obtain bank loans under Section 5209, Revised Statutes. The defendant argued that he had been improperly indicted because his actions did not constitute a crime under the statute in question. However, the court disagreed and upheld his conviction. They found that while some parts of Section 5209 were indeed repealed by later legislation, those changes did not affect the portion of law relevant to this case - which made it illegal for any person to knowingly make false statements for obtaining or influencing bank transactions. Therefore, they concluded that Weber's indictment was valid and affirmed his conviction.

In the dissenting opinion for Weber v. United States, Justice Frank Murphy argued that the majority's decision to uphold Weber's conviction was a violation of his constitutional rights. He contended that the evidence used against Weber had been obtained illegally and should therefore have been excluded from trial. According to Murphy, federal agents violated both Fourth Amendment protections against unreasonable searches and seizures and Fifth Amendment protections against self-incrimination when they intercepted and decoded telegrams sent by Weber without first obtaining a warrant or consent. Furthermore, he criticized the majority for failing to address these constitutional issues in their ruling, arguing that this oversight undermined fundamental principles of justice and fairness in American law enforcement practices.
