In the United States, the Miranda warning is a type of notification customarily given by police to criminal suspects in police custody advising them of their right to silence and, in effect, protection from self-incrimination; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. Named for the U.S. Supreme Court's 1966 decision Miranda v. Arizona, these rights are often referred to as Miranda rights. The purpose of such notification is to preserve the admissibility of their statements made during custodial interrogation in later criminal proceedings. The idea came from law professor Yale Kamisar, who subsequently was dubbed "the father of Miranda."
The Sixth Amendment to the United States Constitution sets forth rights related to criminal prosecutions. It was ratified in 1791 as part of the United States Bill of Rights. The Supreme Court has applied all but one of this amendment's protections to the states through the Due Process Clause of the Fourteenth Amendment.
Gideon v. Wainwright, 372 U.S. 335 (1963), was a landmark U.S. Supreme Court decision in which the Court ruled that the Sixth Amendment of the U.S. Constitution requires U.S. states to provide attorneys to criminal defendants who are unable to afford their own. The case extended the right to counsel, which had been found under the Fifth and Sixth Amendments to impose requirements on the federal government, by imposing those requirements upon the states as well.
Miranda v. Arizona, 384 U.S. 436 (1966), was a landmark decision of the U.S. Supreme Court in which the Court ruled that law enforcement in the United States must warn a person of their constitutional rights before interrogating them, or else the person's statements cannot be used as evidence at their trial. Specifically, the Court held that under the Fifth Amendment to the U.S. Constitution, the government cannot use a person's statements made in response to an interrogation while in police custody as evidence at the person's criminal trial unless they can show that the person was informed of the right to consult with a lawyer before and during questioning, and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights but also voluntarily waived them before answering questions.
Escobedo v. Illinois, 378 U.S. 478 (1964), is a United States Supreme Court case holding that criminal suspects have a right to counsel during police interrogations under the Sixth Amendment. The case was decided a year after the court had held in Gideon v. Wainwright that indigent criminal defendants have a right to be provided counsel at trial.
Barker v. Wingo, 407 U.S. 514 (1972), was a United States Supreme Court case involving the Sixth Amendment to the U.S. Constitution, specifically the right of defendants in criminal cases to a speedy trial. The Court held that determinations of whether or not the right to a speedy trial has been violated must be made on a case-by-case basis, and set forth four factors to be considered in the determination.
In criminal law, self-incrimination is the act of making a statement that exposes oneself to an accusation of criminal liability or prosecution. Self-incrimination can occur either directly or indirectly: directly, by means of interrogation where information of a self-incriminatory nature is disclosed; or indirectly, when information of a self-incriminatory nature is disclosed voluntarily without pressure from another person.
Massiah v. United States, 377 U.S. 201 (1964), was a case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution prohibits the government from eliciting statements from the defendant about themselves after the point that the Sixth Amendment right to counsel attaches.
Colorado v. Connelly, 479 U.S. 157 (1986), was a U.S. Supreme Court case that was initiated by Francis Connelly, who insisted that his schizophrenic episode rendered him incompetent, nullifying his waiver of his Miranda rights.
The Fifth Amendment to the United States Constitution creates several constitutional rights, limiting governmental powers focusing on criminal procedures. It was ratified, along with nine other articles, in 1791 as part of the Bill of Rights.
Texas v. Cobb, 532 U.S. 162 (2001), was a United States Supreme Court case in which the Court held that the Sixth Amendment right to counsel is offense-specific and does not always extend to offenses that are closely related to those where the right has been attached. This decision reaffirmed the Court's holding in McNeil v. Wisconsin (1991) by concluding that the Sixth Amendment right to counsel attaches at the onset of adversarial proceedings.
Fellers v. United States, 540 U.S. 519 (2004), is a United States Supreme Court case regarding the Sixth Amendment's right to counsel.
Michigan v. Jackson, 475 U.S. 625 (1986), was a case decided by the United States Supreme Court regarding the Sixth Amendment's right to counsel in a police interrogation. In a decision written by Justice Stevens, the Court held that once an accused individual has claimed a right to counsel at a plea hearing or other court proceeding, a waiver of that right during later police questioning would be invalid unless the accused individual initiated the communication.
Montejo v. Louisiana, 556 U.S. 778 (2009), is a 5–4 decision by the United States Supreme Court that overruled the Court's decision in Michigan v. Jackson. The case concerned the validity of a defendant's waiver of his right to counsel during a police interrogation. In reversing Jackson, the Court said such a waiver was valid.
Edwards v. Arizona, 451 U.S. 477 (1981), is a decision by the United States Supreme Court holding that once a defendant invokes his Fifth Amendment right to counsel, police must cease custodial interrogation. Re-interrogation is only permissible once defendant's counsel has been made available to him, or he himself initiates further communication, exchanges, or conversations with the police. Statements obtained in violation of this rule are a violation of a defendant's Fifth Amendment rights.
Berghuis v. Thompkins, 560 U.S. 370 (2010), is a landmark decision by the Supreme Court of the United States in which the Court considered the position of a suspect who understands their right to remain silent under Miranda v. Arizona and is aware that they have the right to remain silent, but does not explicitly invoke or waive the right.
Brewer v. Williams, 430 U.S. 387 (1977), is a decision by the United States Supreme Court that clarifies what constitutes "waiver" of the right to counsel for the purposes of the Sixth Amendment. Under Miranda v. Arizona, evidence obtained by police during interrogation of a suspect before he has been read his Miranda rights is inadmissible. Here, however, the defendant had been indicted in court and had asserted his desire to have counsel, thus his Sixth Amendment right to counsel had attached. At issue was whether a voluntary admission of incriminating facts in response to police statements made while the defendant was in custody and outside the presence of his lawyer constituted a waiver of this right to counsel.
The United States Constitution contains several provisions regarding the law of criminal procedure.
The Assistance of Counsel Clause of the Sixth Amendment to the United States Constitution provides: "In all criminal prosecutions, the accused shall enjoy the right...to have the Assistance of Counsel for his defence."
Hemphill v. New York, 595 U.S. ___ (2022), was a decision by the United States Supreme Court involving the application of Confrontation Clause of the Sixth Amendment to the United States Constitution. In its decision, the Court ruled on when a criminal defendant who opens the door to otherwise inadmissible evidence also opens the door to evidence that would otherwise be excluded by the Confrontation Clause.
