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.
Gideon v. Wainwright, 372 U.S. 335 (1963), was a landmark U.S. Supreme Court decision in which the Court ruled that the Sixth Amendment of the U.S. Constitution requires U.S. states to provide attorneys to criminal defendants who are unable to afford their own. 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.
A public defender is a lawyer appointed to represent people who otherwise cannot reasonably afford to hire a lawyer to defend themselves in a trial. Several countries provide people with public defenders, including the UK, Belgium, Hungary and Singapore, and some states of Australia. Brazil is the only country in which an office of government-paid lawyers with the specific purpose of providing full legal assistance and representation to the needy free of charge is established in the constitution. The Sixth Amendment to the US Constitution, as interpreted by the Supreme Court, requires the US government to provide legal counsel to indigent defendants in criminal cases. Public defenders in the United States are lawyers employed by or under contract with county, state or federal governments.
In United States law, ineffective assistance of counsel (IAC) is a claim raised by a convicted criminal defendant asserting that the defendant's legal counsel performed so ineffectively that it deprived the defendant of the constitutional right guaranteed by the Assistance of Counsel Clause of the Sixth Amendment to the United States Constitution. Ineffectiveness claims may only be brought where the defendant had the right to counsel, ordinarily during the critical stages of a prosecution.
Betts v. Brady, 316 U.S. 455 (1942), was a landmark United States Supreme Court case that denied counsel to indigent defendants prosecuted by a state. The reinforcement that such a case is not to be reckoned as denial of fundamental due process was famously overruled by Gideon v. Wainwright. In the dissent, Justice Hugo Black famously opined that "A practice cannot be reconciled with "common and fundamental ideas of fairness and right which subjects innocent men to increased dangers of conviction merely because of their poverty."
In criminal law, the right to counsel means a defendant has a legal right to have the assistance of counsel and, if the defendant cannot afford a lawyer, requires that the government appoint one or pay the defendant's legal expenses. The right to counsel is generally regarded as a constituent of the right to a fair trial. Historically, however, not all countries have always recognized the right to counsel. The right is often included in national constitutions. Of the 194 constitutions currently in force, 153 have language to this effect.
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.
United States v. Olano, 507 U.S. 725 (1993), was a United States Supreme Court case that distinguished between forfeiture and waiver. Quoting from Johnson v. Zerbst, 304 U.S. 458 (1938), the Court noted, "Whereas forfeiture is the failure to make the timely assertion of a right, waiver is the "intentional relinquishment or abandonment of a known right.... Whether a particular right is waivable; whether the defendant must participate personally in the waiver; whether certain procedures are required for waiver; and whether the defendant's choice must be particularly informed or voluntary, all depend on the right at stake."
Turner v. Rogers, 564 U.S. 431 (2011), is a case that was decided by the United States Supreme Court on June 20, 2011, relating to the Due Process Clause of the 14th Amendment. The Court held that Turner was not entitled to a public defender in cases regarding family nonsupport. However, in cases in which a state is not required to provide counsel, it must provide some other safeguard to reduce the risk of erroneous deprivation of liberty in civil contempt cases. The particular case the Court took under review was a child support payment case and the point of contention was the process of the defendant's income determination by the court.
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.
Ludwig v. Massachusetts, 427 U.S. 618 (1976), was a case in which the Supreme Court of the United States held that the Massachusetts two-tier court system did not deprive Ludwig of his U.S. Const., Amend. XIV right to a jury trial and did not violate the double jeopardy clause of the U.S. Const., Amend. V.
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."
In the United States, a public defender is a lawyer 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.
Rock v. Arkansas, 483 U.S. 44 (1987), was a Supreme Court of the United States case in which the Court held that criminal defendants have a constitutional right to testify on their own behalf.
Garza v. Idaho, 586 U.S. ___, 139 S. Ct. 738 (2019), was a case in which the United States Supreme Court held that the presumption of prejudice for Sixth Amendment purposes applies regardless of whether a defendant has waived the right to appeal.
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.
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.
