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.
Maryland v. Craig, 497 U.S. 836 (1990), was a U.S. Supreme Court case involving the Sixth Amendment. The Court ruled that the Sixth Amendment's Confrontation Clause, which provides criminal defendants with the right to confront witnesses against them, did not bar the use of one-way closed-circuit television to present testimony by an alleged child sex abuse victim.
Crawford v. Washington, 541 U.S. 36 (2004), is a landmark United States Supreme Court decision that reformulated the standard for determining when the admission of hearsay statements in criminal cases is permitted under the Confrontation Clause of the Sixth Amendment. The Court held that prior testimonial statements of witnesses who have since become unavailable may not be admitted without cross-examination.
The Confrontation Clause of the Sixth Amendment to the United States Constitution provides that "in all criminal prosecutions, the accused shall enjoy the right…to be confronted with the witnesses against him." The right only applies to criminal prosecutions, not civil cases or other proceedings. Generally, the right is to have a face-to-face confrontation with witnesses who are offering testimonial evidence against the accused in the form of cross-examination during a trial. The Fourteenth Amendment makes the right to confrontation applicable to the states and not just the federal government.
Davis v. Washington, 547 U.S. 813 (2006), was a case decided by the Supreme Court of the United States and written by Justice Antonin Scalia that established the test used to determine whether a hearsay statement is "testimonial" for Confrontation Clause purposes. Two years prior to its publication, in Crawford v. Washington, the Supreme Court held that the Confrontation Clause bars “admission of testimonial statements of a witness who did not appear at trial unless he was unavailable to testify, and the defendant had had a prior opportunity for cross-examination.” The Supreme Court declined to define "testimonial" in Crawford which left lower courts without any guidance. However, in Davis v. Washington, along with Hammon v. Indiana which was consolidated with Davis, the Court clarified the meaning of "testimonial" and articulated a new standard.
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.
Ohio v. Roberts, 448 U.S. 56 (1980), is a United States Supreme Court decision dealing with the Confrontation Clause of the Sixth Amendment to the United States Constitution.
Whorton v. Bockting, 549 U.S. 406 (2007), was a United States Supreme Court case about the application of the Confrontation Clause and whether Crawford v. Washington (2006) applied retroactively. Justice Samuel Alito, writing for a unanimous Court, ruled that Crawford did not apply retroactively.
United States criminal procedure derives from several sources of law: the baseline protections of the United States Constitution; federal and state statutes; federal and state rules of criminal procedure ; and state and federal case law. Criminal procedures are distinct from civil procedures in the US.
Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), is a United States Supreme Court case in which the Court held that it was a violation of the Sixth Amendment right of confrontation for a prosecutor to submit a chemical drug test report without the testimony of the person who performed the test. While the court ruled that the then-common practice of submitting these reports without testimony was unconstitutional, it also held that so called "notice-and-demand" statutes are constitutional. A state would not violate the Constitution through a "notice-and-demand" statute by both putting the defendant on notice that the prosecution would submit a chemical drug test report without the testimony of the scientist and also giving the defendant sufficient time to raise an objection.
Giles v. California, 554 U.S. 353 (2008), was a case decided by the Supreme Court of the United States that held that for testimonial statements to be admissible under the forfeiture exception to hearsay, the defendant must have intended to make the witness unavailable for trial.
Michigan v. Bryant, 562 U.S. 344 (2011), was a United States Supreme Court case in which the Court further developed the "primary purpose" test to determine whether statements are "testimonial" for Confrontation Clause purposes. In Bryant, the Court expanded upon the test first articulated in Davis v. Washington, "addressing for the first time circumstances in which the 'ongoing emergency' discussed in Davis extended to a potential threat to the respond police and the public at large."
United States v. Valenzuela-Bernal, 458 U.S. 858 (1982), is a United States Supreme Court case that determined the constitutionality of deporting aliens who might give testimony in criminal alien smuggling prosecutions. Because deporting alien witnesses might take away a testimony that would be both “material and favorable” to the defendant, it gives rise to a potential motion from the defense to dismiss the indictment under the Compulsory Process Clause of the Sixth Amendment and the Due Process Clause of the Fifth Amendment.
The Supreme Court of the United States handed down fourteen per curiam opinions during its 2011 term, which began October 3, 2011 and concluded September 30, 2012.
Washington v. Texas, 388 U.S. 14 (1967), is a United States Supreme Court case in which the Court decided that the Compulsory Process Clause of the Sixth Amendment to the Constitution is applicable in state courts as well as federal courts. Jackie Washington had attempted to call his co-defendant as a witness, but was blocked by Texas courts because state law prevented co-defendants from testifying for each other, under the theory that they would be likely to lie for each other on the stand.
Taylor v. Illinois, 484 U.S. 400 (1988), is a United States Supreme Court decision in which the Court held that defense witnesses can be prevented from testifying under certain circumstances, even if that hurts the defense's case. Taylor was the first case to hold that there is no absolute bar to blocking the testimony of a surprise witness, even if that is an essential witness for the defendant, a limitation of the broad right to present a defense recognized in Washington v. Texas (1967).
United States v. Mandujano, 425 U.S. 564 (1976), was a United States Supreme Court case that determined that it is not necessary to provide full Miranda warnings to a person called to testify before a grand jury; and that false statements given during that testimony may not be suppressed in a subsequent prosecution for perjury.
Napue v. Illinois, 360 U.S. 264 (1959), was a United States Supreme Court case in which the Court held that the knowing use of false testimony by a prosecutor in a criminal case violates the Due Process Clause of the Fourteenth Amendment to the United States Constitution, even if the testimony affects only the credibility of the witness and does not directly relate to the innocence or guilt of the defendant.
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.
