What legal principle was established in Miranda v. Arizona?

The legal principle established in Miranda v. Arizona is the right to remain silent. This landmark Supreme Court case determined that individuals taken into police custody must be informed of their rights before being interrogated. These rights, now known as "Miranda rights," include the right to remain silent and the right to an attorney. The Court ruled that without this warning, any statements made by the individual during questioning could not be used as evidence in court.

The significance of this ruling is rooted in the Fifth Amendment, which protects against self-incrimination. It ensures that individuals are aware of their rights and can exercise them, thereby safeguarding the fundamental rights of the accused within the criminal justice system. This decision aims to ensure that confessions are made voluntarily and with an understanding of the legal implications, promoting fairness in legal proceedings. The recognition of the right to remain silent has become a foundational aspect of American criminal law and the protection of civil liberties.
