What must a person be advised of before custodial interrogation according to Miranda?

A person must be advised of the right to remain silent before custodial interrogation according to the Miranda decision. This right is a fundamental protection against self-incrimination, ensuring that individuals are aware they do not have to answer questions or provide information that may be used against them in a court of law. The Miranda warning, thus, serves as a safeguard for the individual's Fifth Amendment rights. It informs the person that anything they say can be held against them, thereby allowing them to make an informed decision about whether to speak or remain silent.

While being informed about charges, the right to an appeal, and the right to a speedy trial are also critical legal rights, they do not specifically pertain to the immediate context of custodial interrogation as required by the Miranda ruling. The emphasis is primarily on the right against self-incrimination and the necessity for law enforcement to ensure that a suspect is aware of their legal protections before any questioning begins.
