Miranda was interrogated by police for two hours without being informed of his constitutional rights against self-incrimination and to legal counsel, resulting in him confessing to the crimes charged. His confession was appealed on the grounds that his rights were violated, but the appeal was denied and his conviction upheld. The Supreme Court ultimately ruled 5-4 in favor of Miranda, concluding that defendants in custody must be informed of their rights before interrogation to protect against self-incrimination.
