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."
In a legal dispute, one party has the burden of proof to show that they are correct, while the other party has no such burden and is presumed to be correct. The burden of proof requires a party to produce evidence to establish the truth of facts needed to satisfy all the required legal elements of the dispute.
In the legal system of the United States, a Brady disclosure consists of exculpatory or impeaching information and evidence that is material to the guilt or innocence or to the punishment of a defendant. The term comes from the 1963 U.S. Supreme Court case Brady v. Maryland, in which the Supreme Court ruled that suppression by the prosecution of evidence favorable to a defendant who has requested it violates due process.
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.
Exculpatory evidence is evidence favorable to the defendant in a criminal trial that exonerates or tends to exonerate the defendant of guilt. It is the opposite of inculpatory evidence, which tends to present guilt.
Brady v. Maryland, 373 U.S. 83 (1963), was a landmark United States Supreme Court case that established that the prosecution must turn over all evidence that might exonerate the defendant to the defense. The prosecution failed to do so for Brady, and he was convicted. Brady challenged his conviction, arguing it had been contrary to the Due Process Clause of the Fourteenth Amendment to the United States Constitution.
In United States law, the Aguilar–Spinelli test was a judicial guideline set down by the U.S. Supreme Court for evaluating the validity of a search warrant or a warrantless arrest based on information provided by a confidential informant or an anonymous tip. The Supreme Court abandoned the Aguilar–Spinelli test in Illinois v. Gates, 462 U.S. 213 (1983), in favor of a rule that evaluates the reliability of the information under the "totality of the circumstances." However, Alaska, Hawaii, Massachusetts, New York, Vermont, Oregon, and Washington have retained the Aguilar–Spinelli test, based on their own state constitutions.
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.
Holmes v. South Carolina, 547 U.S. 319 (2006), was a decision by the United States Supreme Court involving the right of a criminal defendant to present evidence that a third party instead committed the crime. The Court vacated the rape and murder conviction in South Carolina of a man who had been denied the opportunity to present evidence of a third party's guilt, because the trial court believed the prosecutor's forensic evidence was too strong for the defendant's evidence to raise an inference of innocence. The Court ruled unanimously that this exclusion violated the right of a defendant to have a meaningful opportunity to present a complete defense, because the strength of a prosecutor's case had no logical relationship to whether a defendant's evidence was too weak to be admissible.
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.
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.
Wilson v. Arkansas, 514 U.S. 927 (1995), is a United States Supreme Court decision in which the Court held that the traditional, common-law-derived "knock and announce" rule for executing search warrants must be incorporated into the "reasonableness" analysis of whether the actual execution of the warrant is/was justified under the 4th Amendment. The high court thus ruled that the old "knock and announce" rule while not a hard requirement, was also not a dead letter.
United States v. White, 401 U.S. 745 (1971), was a United States Supreme Court decision which held that recording conversations using concealed radio transmitters worn by informants does not violate the Fourth Amendment protection against unreasonable searches and seizures, and thus does not require a warrant.
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.
Department of Justice v. Landano, 508 U.S. 165 (1993), was a case in which the Supreme Court of the United States held that the Government is not entitled to a presumption that a source is confidential within the meaning of Exemption 7(D) of the Freedom of Information Act whenever the source provides information to the Federal Bureau of Investigation in the course of a criminal investigation.
The United States Constitution contains several provisions regarding the law of criminal procedure.
Cruz v. New York, 481 U.S. 186 (1987), was a decision by the Supreme Court of the United States in which the Court held, 5–4, that the Confrontation Clause of the Constitution's Sixth Amendment barred the admission, in a joint trial, of a non-testifying codefendant's confession incriminating the defendant, even if the defendant's own confession was admitted against him.
A jailhouse confession is a confession to a crime given by a prisoner to another inmate while in custody. Legal regimes have developed with respect to the use of jailhouse confessions in the prosecution of crimes.
United States v. Bagley, 473 U.S. 667 (1985), was a Supreme Court of the United States case that established the standard for materiality under Brady v. Maryland.
Smith v. Cain, 565 U.S. 73, 132 S. Ct. 627 (2012), is a United States Supreme Court decision clarifying the Brady v. Maryland standard for criminal discovery. Joshua Dressler has called Smith v. Cain the "most recent pronouncement on the discovery issue."
