Key facts: Miranda warnings are required before custodial interrogation and must cover the right to remain silent, the warning that statements can be used as evidence, and the right to an attorney, retained or appointed.[1]

Miranda rights are the warnings police must give a person before a custodial interrogation, informing the person of the right to remain silent and the right to an attorney.[1]The requirement comes from the Supreme Court's 1966 decision in Miranda v. Arizona, which held that statements obtained without the warnings or a valid waiver may be inadmissible at trial.[1]

What the warnings say

The Supreme Court in Miranda v. Arizona held that "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]These warnings stem from the Fifth Amendment privilege against self-incrimination and the Sixth Amendment right to counsel.[1]The exact wording that officers use differs by jurisdiction, but it must convey these same protections.[1]

When Miranda applies: custody and interrogation

The warnings are required only when a person is subjected to custodial interrogation, meaning the person is in custody and being questioned by police.[1]The Court in Miranda described the problem as the admissibility of statements obtained from an individual subjected to custodial police interrogation, and the need for procedures ensuring that the person is accorded the Fifth Amendment privilege not to be compelled to incriminate himself.[2]The decision followed an earlier case in which police took a defendant into custody and interrogated him at a station house without effectively advising him of his right to remain silent or to consult an attorney.[2]More background on how police take someone into custody appears on the page about arrest.

Invoking and waiving the rights

A suspect can waive the Miranda rights, but the waiver must be made voluntarily, knowingly and intelligently.[2]In Berghuis v. Thompkins, the Court explained that a waiver must be the product of a free and deliberate choice rather than intimidation, coercion, or deception, and must be made with full awareness of the nature of the right being abandoned and the consequences of abandoning it.[4]A waiver can be implied from a defendant's silence, coupled with an understanding of the rights and a course of conduct indicating waiver, such as answering a question after being warned.[4]The Court also held that an invocation of the right to remain silent must be unambiguous; if a suspect makes an ambiguous or equivocal statement, or says nothing at all, police are not required to end the interrogation or to ask clarifying questions.[4]Someone who does not have a lawyer present can ask that one be appointed, a right discussed further on the page about public defenders.

What happens if police don't give the warnings

Without a Miranda warning or a valid waiver, statements made during custodial interrogation may be inadmissible at trial under the exclusionary rule, which prevents a party from using evidence gathered in violation of the Constitution.[1]Some states also have statutes addressing involuntary confessions, under which a confession may not be received in evidence if it was obtained in violation of rights the defendant may derive from the state or federal constitution.[1]Because rules on suppression and related procedure can vary, a person facing this situation may want to review the overview of the criminal trial process or consult the starting point for people charged with a crime.

Later cases

Congress later enacted a statute making the admissibility of a suspect's statements turn solely on whether they were voluntary, which a federal appeals court read as overruling Miranda.[3]In Dickerson v. United States, the Supreme Court held that Miranda is a constitutional decision that cannot be overruled by an Act of Congress, and that Miranda and its progeny govern the admissibility of statements made during custodial interrogation in both state and federal courts.[3]The Court noted that Miranda has become embedded in routine police practice to the point that the warnings have become part of national culture, and declined to overrule it.[3]The Court has also made exceptions and refinements to the Miranda framework since 1966, including the rules on waiver and invocation set out in Berghuis v. Thompkins.[3]

Common questions

What does it mean to Mirandize someone?

To Mirandize someone means that police give the person the Miranda warning before custodial interrogation, describing the constitutional rights that apply.[1]This includes informing the person of the right to remain silent, that statements can be used as evidence, and the right to an attorney, retained or appointed.[2]

When are Miranda warnings not required?

Miranda warnings apply specifically to custodial interrogation, so they are tied to a person being in custody and being questioned by police.[1]The sources summarized here focus on that custodial-interrogation requirement; rules on specific situations vary and are not detailed in these sources.

What happens if police don't read Miranda rights?

If police fail to give the warnings or do not obtain a valid waiver, statements made during custodial interrogation may be inadmissible at trial under the exclusionary rule.[1]The Supreme Court has confirmed that this is a constitutional requirement that Congress cannot override by statute.[3]

How do you invoke the right to remain silent?

The Supreme Court has held that the right to remain silent must be invoked unambiguously; silence alone during an interrogation does not invoke it.[4]If a suspect does not clearly state that he wants to remain silent or does not want to talk with police, officers are not required to end the questioning.[4]

Can Miranda rights be waived?

Yes. The Supreme Court held that a defendant may waive the Miranda rights, provided the waiver is made voluntarily, knowingly and intelligently.[2]A waiver can be implied from conduct, such as giving an answer to police after understanding the warnings, even without an express statement giving up the rights.[4]
