Berghuis v. Thompkins

Van Chester Thompkins was advised of his Miranda rights before a police interrogation about a fatal shooting in Michigan. He largely remained silent for about three hours, did not say he wanted to remain silent, did not ask for a lawyer, and eventually answered yes when asked if he prayed to God for forgiveness for the shooting.

He moved to suppress the statement.

The dispute reached the courts because the police action, prosecution, civil-rights claim, or government policy raised a constitutional question that could not be answered by the facts alone.

Does a suspect invoke the Miranda right to remain silent by staying mostly silent during questioning, and can a suspect impliedly waive that right by answering questions after receiving and understanding Miranda warnings?

In plain English, the court had to decide where police authority ended and constitutional protection began under the facts of this case.

No. The Court held that a suspect must invoke the right to remain silent unambiguously. If Miranda warnings are given and understood, an uncoerced statement can establish an implied waiver. Police were not required to stop questioning Thompkins merely because he was largely silent.

The decision matters because the decision gave officers a clearer operational rule: silence alone does not necessarily end questioning after Miranda warnings. For suspects, it made the practical rule stark: to stop custodial questioning, say clearly that you are invoking your right to remain silent or asking for a lawyer.

After Miranda warnings, simply staying quiet may not be enough to stop an interrogation. The right must be clearly invoked, and later voluntary answers can count as a waiver.

Berghuis remains important in interrogation training, suppression motions, and public legal education because it distinguishes silence from a clear invocation of rights. It is especially relevant to custodial interviews where a person responds only after a long period of limited answers.
