In the United States v. Carignan case of 1951, the Supreme Court ruled on a matter concerning confessions and their admissibility in court. The defendant, Joseph Carignan, was convicted for murder based largely on his own confession to police officers while he was under arrest for another crime. He appealed his conviction arguing that his confession should not have been admitted because it had been obtained without informing him of his right to counsel or warning him about self-incrimination risks. The Supreme Court agreed with Carignan's argument and reversed the judgment by a vote of 5-4. It held that even though there is no absolute rule requiring law enforcement officials to inform an accused person of their rights before any questioning occurs, circumstances surrounding each case must be considered individually when determining whether a confession is voluntary or coerced.

In the dissenting opinion for United States v. Carignan, Justice Jackson disagreed with the majority's decision to overturn Carignan's conviction based on a lack of corroborating evidence supporting his confession. He argued that there was sufficient circumstantial evidence in this case and that it should be up to juries, not appellate courts, to decide whether such evidence is enough to support a conviction. Furthermore, he contended that requiring corroboration for every detail of a confession would make it nearly impossible for prosecutors to secure convictions in cases where confessions are crucial pieces of evidence. This could potentially allow guilty individuals go free simply because they confessed too much or provided details about their crimes which couldn't be independently verified.
