Berghuis v. Thompkins
Citation
560 U.S. 370 (2010). Supreme Court of the United States.
Facts
Van Chester Thompkins was suspected of murder. Police gave him Miranda warnings at the outset of interrogation. For nearly three hours Thompkins sat largely silent, offering one- or two-word answers. Near the end of the session he made several incriminating statements. He was convicted of murder and challenged his statements as obtained in violation of Miranda.
Issue
(1) Does a valid Miranda waiver require an explicit, affirmative waiver, or may waiver be implied from conduct? (2) Must a suspect affirmatively and unambiguously invoke the right to remain silent, or does prolonged silence itself constitute invocation?
Holding
The Court held that Thompkins implicitly waived his Miranda rights by answering questions after being warned. There is no requirement of an express waiver. Additionally, mere silence during questioning does not constitute an unambiguous invocation of the right to remain silent; the suspect must affirmatively and unambiguously assert the right.
Rule / Doctrine
A Miranda waiver need not be explicit; it may be implied from a suspect’s course of conduct — including answering questions after being read rights. To invoke the right to remain silent, a suspect must do so unambiguously. The burden falls on the suspect to invoke, not on police to clarify ambiguous silence. An uncoerced statement after Miranda warnings is itself strong evidence of waiver.
Significance
Berghuis significantly narrowed Miranda’s protective scope. By holding that waiver can be implied and that silence is not invocation, the Court shifted the burden onto suspects, making it easier for police to secure admissible statements after lengthy, initially silent interrogations. It is a major counterweight to Miranda v. Arizona and is frequently paired with Davis v. United States (requiring unambiguous invocation of counsel).
