Brief Fact Summary. Petitioner was charged with selling heroin on multiple occasions to an undercover police officer. At trial, Petitioner testified that the bags did not contain heroin, but had baking powder inside.
Synopsis of Rule of Law. Evidence inadmissible for lack of Miranda warnings does not prevent the admission of the evidence for all purposes if the admission satisfies another legal admission, such as impeachment.
Issue. Was the prosecution improperly allowed to use the statements to impeach Petitioner’s testimony since the statements were made without Miranda warnings?
Held. Chief Justice Burger issued the opinion for the United States Supreme Court in holding that Petitioner was allowed to be impeached using his conflicting statements.
Dissent. Justice Black dissented without comment.
Justice Brennan, joined by Justices Douglas and Marshall issued an opinion arguing that the Court’s ruling supports police officers who don’t follow the law by not properly giving Miranda warnings. He notes that police may be encouraged to interrogate without proper warnings because while the prosecution may not be able to use the statements in its direct case, it may be allowed to do so if the defendant chooses to testify.
Discussion. The Court found that a defendant should not be allowed to commit perjury, and if impeachment evidence is available and admissible for that purpose, then the lack of Miranda warning should not prevent it. If Petitioner’s statement had been to a third party instead of police, there would have been little question as to the admissibility.
