Key facts: The Supreme Court held in 1966 that statements made during custodial police interrogation are inadmissible unless the suspect was first told of the right to remain silent and the right to an attorney[1], a constitutional rule that Congress could not override and that the Court later declined to overrule.[3]

Miranda v. Arizona is a 1966 U.S. Supreme Court decision holding that police must inform a suspect of certain constitutional rights before custodial interrogation.[1]The decision is the source of the now-familiar Miranda warnings that officers read to suspects they take into custody.[2]

Background

Miranda v. Arizona combined four cases in which law enforcement officers took a defendant into custody and questioned him at a police station in order to obtain a confession.[1]The Court explained that it had previously addressed related issues in Escobedo v. Illinois, where officers did not effectively advise the defendant of his right to remain silent or his right to consult an attorney, denied his request to speak with counsel, and prevented his retained attorney from consulting with him during a lengthy interrogation that produced a confession later used against him at trial.[1]The Court had held that confession constitutionally inadmissible, and by the time Miranda reached the Court, that earlier decision had become the subject of extensive judicial interpretation and debate among courts, scholars, police, and prosecutors.[1]The cases are closely tied to broader constitutional rights of the accused, including the Fifth Amendment privilege against self-incrimination and the Sixth Amendment right to counsel.[2]

The question before the Court

The Court framed the dispute as going to the roots of American criminal jurisprudence: what restraints the Constitution places on the government when it prosecutes individuals for crime, specifically regarding the admissibility of statements obtained through custodial police interrogation.[1]The Court said it granted review in order to further explore the application of the privilege against self-incrimination to in-custody interrogation and to give concrete constitutional guidelines for law enforcement agencies and courts to follow.[1]This connects directly to the broader topic of the arrest process and what happens once a person is taken into custody as part of the criminal process.

The decision

The Court reaffirmed the constitutional rights at stake, describing them as rooted in the guarantee that no person shall be compelled in a criminal case to be a witness against himself and the guarantee that the accused shall have the assistance of counsel.[1]The Court traced the privilege against self-incrimination to a historical reaction against inquisitorial methods of questioning accused persons, methods that the Court said had become so odious that they gave rise to a demand for abolition and became embedded in American jurisprudence.[1]Building on this history, the Court held that a defendant cannot be questioned by police in a custodial interrogation until the defendant is made aware of the right to remain silent, the right to consult an attorney and have the attorney present during questioning, and the right to have an attorney appointed if indigent.[2]Without a valid warning or a valid waiver of these rights, any resulting statements may be inadmissible at trial under the exclusionary rule.[2]The ruling is closely associated with the page on Miranda rights and with broader discussion of the Fifth Amendment.

The warnings

The Court specifically held: "Prior to any questioning, the person must be warned that he has a right to remain silent, that any statement he does make may be used as evidence against him, and that he has a right to the presence of an attorney, either retained or appointed".[2]The Court added that a defendant may waive these rights, but only if the waiver is made voluntarily, knowingly, and intelligently.[2]The exact wording that police use to deliver these warnings differs by jurisdiction, since the Court set out the required substance rather than a single mandatory script.[2]For readers who want a closer look at how these warnings function in practice, the page on Miranda rights covers that topic in more detail, and arrest explains where in the process these warnings become relevant.

Dissents

The sources provided here do not include the text of the dissenting opinions in Miranda, so their specific reasoning is not detailed in this overview; rules and views on this subject can vary, and readers interested in the full range of opinions should consult the complete Court record.[1]

Later developments

Congress later enacted 18 U.S.C. § 3501, which made the admissibility of a custodial statement turn solely on whether it was made voluntarily, without a warning requirement, and a federal appeals court concluded that this statute effectively overruled Miranda because Miranda was not a constitutional holding.[3]In Dickerson v. United States, the Supreme Court disagreed, holding that Miranda announced a constitutional rule that could not be overruled by an Act of Congress, pointing to the fact that Miranda and its companion cases applied to state court proceedings and that the Miranda opinion itself was replete with statements indicating the majority believed it was announcing a constitutional rule.[3]The Dickerson Court also declined to overrule Miranda on its own, reasoning that Miranda had become embedded in routine police practice to the point where the warnings had become part of the national culture, and that no special justification existed to depart from that precedent under principles of stare decisis.[3]In a later case, Berghuis v. Thompkins, the Court held that a suspect's silence during interrogation, after being advised of the Miranda rights, does not by itself invoke the right to remain silent, and that an uncoerced statement made after a suspect understood the Miranda warnings can establish an implied waiver of that right.[4]These later cases show how courts continue to interpret Miranda within the broader framework of the criminal trial process and the admissibility of evidence against a defendant.

Common questions

What happened in Miranda v. Arizona?

The case combined four separate instances in which police took a defendant into custody and questioned him at a station house to obtain a confession, without effectively advising some defendants of their right to remain silent or to consult an attorney.[1]The Supreme Court used these cases to decide what the Constitution requires before statements from a custodial interrogation can be used against a defendant.[1]

What did the Supreme Court decide?

The Court held that police must tell a suspect, before any custodial questioning, that the suspect has the right to remain silent, that anything said can be used as evidence, and that the suspect has a right to an attorney, retained or appointed.[2]A defendant may waive these rights, but only if the waiver is voluntary, knowing, and intelligent, and without a valid warning or waiver, statements obtained may be inadmissible at trial.[2]

Has Miranda been overruled?

No. In Dickerson v. United States, the Supreme Court held that Miranda is a constitutional decision that Congress could not override by statute, and the Court declined to overrule Miranda itself, citing the fact that the warnings had become embedded in routine police practice.[3]

Does staying silent automatically protect a suspect's rights?

Not necessarily. In Berghuis v. Thompkins, the Court held that a suspect's silence during interrogation does not by itself invoke the right to remain silent, and that the right to remain silent or the right to counsel generally must be invoked unambiguously.[4]An uncoerced statement made after the suspect understood the warnings can be treated as an implied waiver of the right to remain silent.[4]

Do the exact words of a Miranda warning matter?

The Supreme Court specified the substance that must be conveyed before custodial questioning, but the precise wording used by officers differs from one jurisdiction to another.[2]General discussion of how these warnings apply appears on the page about Miranda rights, though rules and practices can vary by state.
