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; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. These rights are often referred to as Mirandarights. The purpose of such notification is to preserve the admissibility of their statements made during custodial interrogation in later criminal proceedings.
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 most of the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
Gideon v. Wainwright, 372 U.S. 335 (1963), is a landmark case in United States Supreme Court history. In it, the Supreme Court unanimously ruled that states are required under the Sixth Amendment of the U.S. Constitution to provide an attorney to defendants in criminal cases who are unable to afford their own attorneys. 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.
Nix v. Whiteside, 475 U.S. 157 (1986), was a United States Supreme Court decision that dealt with the effective assistance of counsel during a criminal trial.
In Powell v. Alabama, 287 U.S. 45 (1932), the United States Supreme Court reversed the convictions of nine young black men for allegedly raping two white women on a freight train near Scottsboro, Alabama. The majority of the Court reasoned that the right to retain and be represented by a lawyer was fundamental to a fair trial and that at least in some circumstances, the trial judge must inform a defendant of this right. In addition, if the defendant cannot afford a lawyer, the court must appoint one sufficiently far in advance of trial to permit the lawyer to prepare adequately for the trial.
Escobedo v. Illinois, 378 U.S. 478 (1964), was 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 held in Gideon v. Wainwright that indigent criminal defendants had a right to be provided counsel at trial.
Alabama v. Shelton, 535 U.S. 654 (2002), was a United States Supreme Court case in which the Court upheld the Alabama Supreme Court's ruling that counsel must be provided for the accused in order to impose a suspended prison sentence.
Johnson v. Zerbst, 304 U.S. 458 (1938), was a United States Supreme Court case, in which the petitioner, Johnson, had been convicted in federal court of feloniously possessing, uttering, and passing counterfeit money in a trial where he had not been represented by an attorney but instead by himself. Johnson filed for habeas corpus relief, claiming that his Sixth Amendment right to counsel had been violated, but he was denied by both a federal district court and the court of appeals.
McNeil v. Wisconsin, 501 U.S. 171 (1991), held that the right to counsel secured by the Sixth Amendment and the right to counsel protected by Miranda v. Arizona are separate and distinct, such that invoking one does not implicitly invoke the other.
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.
Strickland v. Washington, 466 U.S. 668 (1984), was a decision by the Supreme Court of the United States that established the standard for determining when a criminal defendant's Sixth Amendment right to counsel is violated by that counsel's inadequate performance.
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.
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.
Rothgery v. Gillespie County, 554 U.S. 191 (2008), is a United States Supreme Court case in which the Court held that a criminal defendant's initial appearance before a magistrate judge, where he learns the charge against him and his liberty is subject to restriction, marks the initiation of adversary judicial proceedings that trigger attachment of the Sixth Amendment right to counsel. Attachment does not also require that a prosecutor be aware of that initial proceeding or involved in its conduct.
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.
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."
In the United States, a public defender is an attorney-at-law appointed by the courts and provided by the state or federal governments to represent and advise those who cannot afford to hire a private attorney. Public defenders are full time attorneys employed by the state or federal governments. The public defender program is one of several types of criminal legal aid in the United States.
Pointer v. Texas, 380 U.S. 400 (1965), was a decision by the United States Supreme Court involving the application of the right of to confront accusers in state court proceedings. The Sixth Amendment in the Bill of Rights states that, in criminal prosecutions, the defendant has a right "...to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor..." In this case, a person arrested in Texas for robbery was deprived of the ability to cross-examine a witness when the lower court allowed the introduction of a transcript of that witness's earlier testimony at a preliminary proceeding instead of compelling attendance by the witness at trial.
Cone v. Bell, 556 U.S. 449 (2009), was a case in which the United States Supreme Court held that a defendant was entitled to a hearing to determine whether prosecutors in his 1982 death penalty trial violated his right to due process by withholding exculpatory evidence. The defendant, Gary Cone, filed a petition for postconviction relief from a 1982 death sentence in which he argued that prosecutors violated his rights to due process under the Fourteenth Amendment by withholding police reports and witness statements that potentially could have shown that his drug addiction affected his behavior. In an opinion written by Justice John Paul Stevens, the Supreme Court held that Cone was entitled to a hearing to determine whether the prosecution's failure to disclose exculpatory evidence violated Cone's right to due process; the Court noted that "the quantity and the quality of the suppressed evidence lends support to Cone’s position at trial that he habitually used excessive amounts of drugs, that his addiction affected his behavior during his crime spree". In 2016, Gary Cone died from natural causes while still sitting on Tennessee's death row.
