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 the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
Miranda v. Arizona, 384 U.S. 436 (1966), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Fifth Amendment to the U.S. Constitution restricts prosecutors from using a person's statements made in response to interrogation in police custody as evidence at their trial unless they can show that the person was informed of the right to consult with an attorney before and during questioning, and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights, but voluntarily waived them.
Mapp v. Ohio, 367 U.S. 643 (1961), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the exclusionary rule, which prevents prosecutors from using evidence in court that was obtained by violating the Fourth Amendment to the U.S. Constitution, applies not only to the federal government but also to the U.S. state governments. The Supreme Court accomplished this by use of a principle known as selective incorporation; in Mapp this involved the incorporation of the provisions, as interpreted by the Court, of the Fourth Amendment which is applicable only to actions of the federal government into the Fourteenth Amendment's due process clause which is applicable to actions of the states.
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.
Olmstead v. United States, 277 U.S. 438 (1928), was a decision of the Supreme Court of the United States, in which the Court reviewed whether the use of wiretapped private telephone conversations, obtained by federal agents without judicial approval and subsequently used as evidence, constituted a violation of the defendant’s rights provided by the Fourth and Fifth Amendments. In a 5–4 decision, the Court held that neither the Fourth Amendment nor the Fifth Amendment rights of the defendant were violated. This decision was overturned by Katz v. United States in 1967.
Arizona v. Fulminante, 499 U.S. 279 (1991), was a United States Supreme Court case clarifying the standard of review of a criminal defendant's allegedly coerced confession. The ruling was divided into parts, with various justices voting in different ways on different points of law, but ultimately 1) the defendant's confession was ruled involuntary, 2) the harmless error rule had to be applied, and 3) in this case, use of the confession as evidence was not harmless.
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 v. Gonzalez-Lopez, 548 U.S. 140 (2006), is a United States Supreme Court ruling that the erroneous deprivation of a defendant's attorney of choice entitles him to a reversal of his conviction under the Sixth Amendment to the United States Constitution.
The Fifth Amendment (Amendment V) to the United States Constitution addresses criminal procedure and other aspects of the Constitution. It was ratified, along nine other articles, in 1791 as part of the Bill of Rights. The Fifth Amendment applies to every level of the government, including the federal, state, and local levels, in regard to a US citizen or resident of the US. The Supreme Court furthered the protections of this amendment through the Due Process Clause of the Fourteenth Amendment.
Griffin v. California, 380 U.S. 609 (1965), was a United States Supreme Court case in which the Court ruled, by a 6–2 vote, that it is a violation of a defendant's Fifth Amendment rights for the prosecutor to comment to the jury on the defendant's declining to testify, or for the judge to instruct the jury that such silence is evidence of guilt.
The Compulsory Process Clause within the Sixth Amendment to the United States Constitution lets criminal case defendants attain witnesses in their favor by way of a court-ordered subpoena. The Clause is generally interpreted as letting defendants present their own case at trial, though several specific limitations have been placed by the Supreme Court of the United States since this rule began.
Griffin v. Illinois, 351 U.S. 12 (1956), was a case in which United States Supreme Court held that a criminal defendant may not be denied the right to appeal by inability to pay for a trial transcript.
Estelle v. Williams, 425 U.S. 501 (1976), is a Supreme Court case involving Harry Lee Williams' conviction of assault on his former landlord in Harris County, Texas. While awaiting trial Williams was unable to post bail. He was tried in his prison uniform, and later was found guilty. He sought a writ of habeas corpus saying being tried in a prison uniform violated his Constitutional rights in accordance with the 14th Amendment. The Court of Appeals ruled that the accused does not have to stand trial in identifiable prison clothes and Williams’ right to due process was violated. The Supreme Court reversed, reinstating the conviction, on June 21, 1976.
Vasquez v. Hillery, 474 U.S. 254 (1986), is a United States Supreme Court case, which held that a defendant's conviction must be reversed if members of their race were systematically excluded from the grand jury that indicted them, even if they were convicted following an otherwise fair trial.
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).
Davis v. Ayala, 576 U.S. 257 (2015), was a case in which the Supreme Court of the United States upheld a death sentence of a Hispanic defendant despite the fact that all Blacks and Hispanics were rejected from the jury during the defendant's trial. The case involved a habeas corpus petition submitted by Hector Ayala, who was arrested and tried in the late 1980s for the alleged murder of three individuals during an attempted robbery of an automobile body shop in San Diego, California in April 1985. At trial, the prosecution used peremptory challenges to strike all Black and Hispanic jurors who were available for jury service. The trial court judge allowed the prosecution to explain the basis for the peremptory challenges outside the presence of Ayala's counsel, "so as not to disclose trial strategy". Ayala was ultimately sentenced to death, but he filed several appeals challenging the constitutionality of the trial court's decision to exclude his counsel from the hearings.
Kimmelman v. Morrison, 477 U.S. 365 (1986), was a decision of the U.S. Supreme Court that clarified the relationship of the right to effective assistance of counsel under the Sixth Amendment to other constitutional rights in criminal procedure. In this case, evidence against the defendant was probably seized illegally, violating the Fourth Amendment, but he lost the chance to argue that point due to his lawyer's ineffectiveness. The prosecution argued that the defendant's attempt to make a Sixth Amendment argument via a habeas corpus petition was really a way to sneak his Fourth Amendment argument in through the back door. The Court unanimously disagreed, and held that the Fourth Amendment issue and the Sixth Amendment issue represented different constitutional values, and had different requirements for prevailing in court, and therefore were to be treated separately by rules of procedure. Therefore, the habeas corpus petition could go forward. In its opinion, the Court also gave guidance on how to apply its decisions in Stone v. Powell and Strickland v. Washington.
Stone v. Powell, 428 U.S. 465 (1976), was decision of the Supreme Court of the United States that limited which claims of Fourth Amendment violations could be made by state prisoners in habeas corpus petitions in federal courts. Specifically, a claim that the exclusionary rule had been broken would be barred if state courts had already given it a full and fair hearing. The decision combined two cases that were argued before the Supreme Court on the same day with similar issues, one filed by Lloyd Powell and the other, titled Wolff v. Rice, filed by David Rice.
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.
