Common questions

Does being questioned at a police station automatically make an interrogation custodial?+

Not by itself. Courts look at whether a reasonable person in that situation would feel free to leave, so a suspect who voluntarily comes in, is told they can go, and is not physically restrained may not be in custody even at a station house.

What happens to a confession obtained without the required warning during custodial interrogation?+

In jurisdictions that follow the Miranda rule, the statement is generally inadmissible in the prosecution's case in chief, though it may still be usable for limited purposes such as impeachment depending on the jurisdiction.
