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.
"Twinkie defense" is a derisive label for an improbable legal defense. It is not a recognized legal defense in jurisprudence, but a catch-all term coined by reporters during their coverage of the trial of defendant Dan White for the murders of San Francisco city Supervisor Harvey Milk and Mayor George Moscone. White's defense was that he suffered diminished capacity as a result of his depression, a symptom of which was a change in diet from healthy food to Twinkies and other sugary foods. Contrary to common belief, White's attorneys did not argue that the Twinkies were the cause of White's actions, but that their consumption was symptomatic of his underlying depression. The product itself was only mentioned in passing during the trial. White was convicted of voluntary manslaughter rather than first-degree murder, and served five years in prison.
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.
In United States and Canadian law, competence concerns the mental capacity of an individual to participate in legal proceedings or transactions, and the mental condition a person must have to be responsible for his or her decisions or acts. Competence is an attribute that is decision-specific. Depending on various factors which typically revolve around mental function integrity, an individual may or may not be competent to make a particular medical decision, a particular contractual agreement, to execute an effective deed to real property, or to execute a will having certain terms.
Faretta v. California, 422 U.S. 806 (1975), was a case in which the Supreme Court of the United States held that criminal defendants have a constitutional right to refuse counsel and represent themselves in state criminal proceedings.
Panetti v. Quarterman, 551 U.S. 930 (2007), is a decision by the Supreme Court of the United States, ruling that criminal defendants sentenced to death may not be executed if they do not understand the reason for their imminent execution, and that once the state has set an execution date death-row inmates may litigate their competency to be executed in habeas corpus proceedings. This decision reaffirmed the Court's prior holdings in Ford v. Wainwright, and Stewart v. Martinez-Villareal.
In the United States criminal justice system, a competency evaluation is an assessment of the ability of a defendant to understand and rationally participate in a court process.
Dusky v. United States, 362 U.S. 402 (1960), was a landmark United States Supreme Court case in which the Court affirmed a defendant's right to have a competency evaluation before proceeding to trial. The Court outlined the basic standards for determining competency.
Frendak v. United States, 408 A.2d 364 is a landmark case in which District of Columbia Court of Appeals decided that a judge could not impose an insanity defense over the defendant's objections.
Godinez v. Moran, 509 U.S. 389 (1993), was a landmark decision in which the U.S. Supreme Court ruled that if a defendant was competent to stand trial, they were automatically competent to plead guilty, and thereby waive the panoply of trial rights, including the right to counsel.
Cooper v. Oklahoma, 517 U.S. 348 (1996), was a United States Supreme Court case in which the Court reversed an Oklahoma court decision holding that a defendant is presumed to be competent to stand trial unless he proves otherwise by the second highest legal standard of proof, that of clear and convincing evidence, ruling that to be unconstitutional. The court said the defendant's Fourteenth Amendment rights to due process were violated.
McKaskle v. Wiggins, 465 U.S. 168 (1984), is a United States Supreme Court case in which the court considered the role of standby counsel in a criminal trial where the defendant conducted his own defense. In this case the defendant claimed his Sixth Amendment right to present his own case in a criminal trial was violated by the presence of a court-appointed standby counsel.
Pro se legal representation comes from Latin pro se, meaning "for oneself" or "on behalf of themselves" which, in modern law, means to argue on one's own behalf in a legal proceeding, as a defendant or plaintiff in civil cases, or a defendant in criminal cases, rather than have representation from counsel or an attorney.
Martinez v. Court of Appeal of California, 528 U.S. 152 (2000), is a United States Supreme Court case in which the Court decided an appellant who was the defendant in a criminal case cannot refuse the assistance of counsel on direct appeals. This case is in contrast to Faretta v. California, 422 U.S. 806 (1975), which grants criminal defendants the right to refuse counsel for trial purposes.
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."
Lafler v. Cooper, 566 U.S. 156 (2012), was a United States Supreme Court case in which the Court clarified the Sixth Amendment standard for reversing convictions due to ineffective assistance of counsel during plea bargaining. The Court ruled that when a lawyer's ineffective assistance leads to the rejection of a plea agreement, a defendant is entitled to relief if the outcome of the plea process would have been different with competent advice. In such cases, the Court ruled that the Sixth Amendment requires the trial judge to exercise discretion to determine an appropriate remedy.
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.
Iowa v. Tovar, 541 U.S. 77 (2004), was a unanimous decision of the Supreme Court of the United States that clarified how well-informed a defendant had to be to waive their right to counsel under the Sixth Amendment. The defendant in this case had waived his right to counsel and pled guilty to drunk driving, and then had been convicted of drunk driving twice more, with sentences increasing as his convictions piled up. He argued that the judge in the first case had not explained that multiple drunk driving convictions would lead to more severe sentences, so his waiver of counsel had been invalid. The Supreme Court disagreed, saying that the judge's warnings had been adequate, and the defendants' waiver was "knowing, voluntary, and intelligent."
