Michigan v. Mosley, 423 U.S. 96 (1975)

Facts

  • Richard Bert Mosley was arrested in Detroit in connection with restaurant robberies and was taken to police headquarters.
  • Police gave Mosley Miranda warnings, and he signed a rights notification certificate.
  • During questioning about the robberies, Mosley stated he did not want to discuss them; the detective immediately stopped the interrogation.
  • More than two hours later, while Mosley remained in custody, a different detective gave fresh Miranda warnings and questioned Mosley about an unrelated homicide.
  • After initially denying involvement, Mosley made inculpatory statements about the homicide.
  • Mosley was charged with first-degree murder; the trial court denied his motion to suppress and admitted the statements, and Mosley was convicted and sentenced to mandatory life imprisonment.
  • The Michigan Court of Appeals reversed, treating any renewed interrogation after invocation of silence as a per se Miranda violation; the Michigan Supreme Court denied review.

Issues

  1. Whether Miranda imposes a per se rule barring any later police interrogation after a suspect invokes the right to remain silent.
  2. Whether Mosley’s later statement was admissible because police “scrupulously honored” his initial decision to cut off questioning.

Decision

  • The Supreme Court reversed the Michigan Court of Appeals and upheld admission of Mosley’s statement.
  • The Court rejected a categorical ban on re-initiating interrogation after invocation of the right to remain silent.
  • The Court held Mosley’s right to cut off questioning was “scrupulously honored” because:
    • questioning about the robberies stopped immediately upon his refusal;
    • a significant interval (over two hours) passed before renewed questioning;
    • fresh Miranda warnings were given and Mosley waived his rights before speaking;
    • the second interview was conducted by a different officer and was limited to a different crime.
  • Invocation of the right to remain silent requires police to stop interrogation, but it does not automatically bar all later questioning.
  • The admissibility of statements obtained after an invocation of silence turns on whether police “scrupulously honored” the suspect’s right to cut off questioning.
  • Relevant factors include immediate cessation of the first interrogation, passage of time, renewed Miranda warnings, change in interrogator or location, limiting renewed questioning to a different subject, and absence of pressure to reconsider.
  • The right-to-silence framework is distinct from stricter limits that apply when a suspect invokes the right to counsel.

Conclusion

A suspect’s decision to remain silent must be respected at the time it is invoked, but police may later re-approach and question the suspect if the initial refusal is scrupulously honored through a meaningful break, renewed warnings, and noncoercive, properly limited interrogation.
