Police arrested and detained 15 year old Ernesto Miranda and held him for questioning.
Miranda was found guilty of rape and kidnapping, after a recorded confession presented by the police. He was sentenced to 20 years in prison.
This case was brought to the Supreme Court because the arresting officer on Miranda's case failed to inform Miranda of his right to an attorney and his right to protect himself against self-incrimination.
The Supreme Court ruled in a 5-4 decision that prosecution could not use Miranda's confession in court since the police did not inform Miranda of his rights
The reasoning behind some of the judges who opposed the ruling were that Miranda had confessed to the crimes and therefore was guilty regardless of the police's mistreatment of his case.
