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.
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.
Frisbie v. Collins, 342 U.S. 519 (1952), is a decision by the United States Supreme Court, holding that kidnapping of a defendant by State authorities for the purpose of taking a suspect from one jurisdiction to another for criminal trial, is constitutional. The defendant was tried in Michigan after being abducted by Michigan authorities in Chicago, Illinois. The case relied upon Ker v. Illinois (1886). The Ker–Frisbie doctrine, continues to be used to uphold convictions based on illegal arrests.
Paul v. Davis, 424 U.S. 693 (1976), is a United States Supreme Court case in which a sharply divided Court held that the plaintiff, whom the local police chief had named an "active shoplifter," suffered no deprivation of liberty resulting from injury to his reputation. In the case, the court broke from precedents and restricted the definition of the constitutional right to privacy "to matters relating to 'marriage procreation, contraception, family relationships, and child rearing and education".
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.
McNally v. United States, 483 U.S. 350 (1987), was a case in which the United States Supreme Court decided that the federal statute criminalizing mail fraud applied only to the schemes and artifices defrauding victims of money or property, as opposed to those defrauding citizens of their rights to good government. The case was superseded one year later when the United States Congress amended the law to specifically include honest services fraud in the mail and wire fraud statutes.
North v. Russell, 427 U.S. 328 (1976), is a United States Supreme Court case which held that a non-lawyer jurist can constitutionally sit in a jail-carrying criminal case provided that the defendant has an opportunity through an appeal to obtain a second trial before a judge who is a lawyer.
Bullcoming v. New Mexico, 564 U.S. 647 (2011), is a significant 6th Amendment Confrontation Clause case decided by the United States Supreme Court. On June 23, 2011, the Supreme Court considered the issue whether a defendant's Confrontation Clause rights extend to a non-testifying laboratory analyst whose supervisor testifies as to test results that the analyst transcribed from a machine. In a five to four decision authored by Justice Ginsburg, the Court held that the second surrogate analyst could not testify about the testimonial statements in the forensic report of the certifying analyst under the Confrontation Clause.
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 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."
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.
North Carolina v. Pearce, 395 U.S. 711 (1969), is a United States Supreme Court case that forbids judicial “vindictiveness” from playing a role in the increased sentence a defendant receives after a new trial. In sum, due process requires that a defendant be “free of apprehension” of judicial vindictiveness. Time served for a new conviction of the same offense must be “fully credited,” and a trial judge seeking to impose a greater sentence on retrial must affirmatively state the reasons for imposing such a sentence. The companion case, Simpson v. Rice, was identical except that the defendant initially pleaded guilty and received only one trial after withdrawing that plea. Simpson was later overruled in Alabama v. Smith.
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).
Powers v. Ohio, 499 U.S. 400 (1991), was a United States Supreme Court case that re-examined the Batson Challenge. Established by Batson v. Kentucky, 476 U.S. 79 (1986), the Batson Challenge prohibits jury selectors from using peremptory challenges on the basis of race, ethnicity, gender, and sex. Powers expanded the jurisdictions of this principle, allowing all parties within a case, defendants especially, to question preemptory challenges during a jury selection, regardless of race. This holding was protected under the Equal Protection Clause of the Fourteenth Amendment.
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.
United States v. Gagnon, 470 U.S. 522 (1985), was a United States Supreme Court case in which the Court held that a criminal defendant's rights under the Fifth Amendment Due Process Clause were not violated by the in camera discussion between the judge and a juror. A defendant has the right to be present at any stage of the trial where the fairness of the proceeding would be impeded by their absence.
