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.
Jury nullification (US), jury equity (UK), or a perverse verdict (UK) generally occurs when members of a criminal trial jury believe that a defendant is guilty, but choose to acquit the defendant anyway, because the jurors consider that the law itself is unjust, that the prosecutor has misapplied the law in the defendant's case, or that the potential punishment for breaking the law is too harsh. Some juries have also refused to convict due to their own prejudices in favour of the defendant.
Batson v. Kentucky, 476 U.S. 79 (1986), was a landmark decision of the US Supreme Court ruling that a prosecutor's use of a peremptory challenge in a criminal case—the dismissal of jurors without stating a valid cause for doing so—may not be used to exclude jurors based solely on their race. The Court ruled that this practice violated the Equal Protection Clause of the Fourteenth Amendment. The case gave rise to the term Batson challenge, an objection to a peremptory challenge based on the standard established by the Supreme Court's decision in this case. Subsequent jurisprudence has resulted in the extension of Batson to civil cases and cases where jurors are excluded on the basis of sex.
Powell v. Alabama, 287 U.S. 45 (1932), was a landmark United States Supreme Court decision in which the 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.
Strauder v. West Virginia, 100 U.S. 303 (1880), was a landmark decision of the Supreme Court of the United States about racial discrimination and United States constitutional criminal procedure. Strauder was the first instance where the Supreme Court reversed a state court decision denying a defendant's motion to remove his criminal trial to federal court pursuant to Section 3 of the Civil Rights Act of 1866.
Moore et al. v. Dempsey, 261 U.S. 86 (1923), was a United States Supreme Court case in which the Court ruled 6-2 that the defendants' mob-dominated trials deprived them of due process guaranteed by the Due Process Clause of the Fourteenth Amendment. It reversed the district court's decision declining the petitioners' writ of habeas corpus. This case was a precedent for the Supreme Court's review of state criminal trials in terms of their compliance with the Bill of Rights.
Bigby v. Dretke 402 F.3d 551, the U.S. Court of Appeals for the Fifth Circuit heard a case appealed from the United States District Court for the Northern District of Texas on the issue of the instructions given to a jury in death penalty sentencing. The decision took into account the recent United States Supreme Court decisions concerning the relevance of mitigating evidence in sentencing, as in Penry v. Lynaugh.
Apodaca v. Oregon, 406 U.S. 404 (1972), was a United States Supreme Court case in which the Court held that state juries may convict a defendant by a less-than-unanimous verdict in a felony criminal case. The four-justice plurality opinion of the court, written by Justice White, affirmed the judgment of the Oregon Court of Appeals, and held that there was no constitutional right to a unanimous verdict. Although federal law requires federal juries to reach criminal verdicts unanimously, the Court held Oregon's practice did not violate the Sixth Amendment right to trial by jury and so allowed it to continue. In Johnson v. Louisiana, a case decided on the same day, the Court held that Louisiana's similar practice of allowing criminal convictions by a jury vote of 9–3 did not violate due process or equal protection under the Fourteenth Amendment.
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.
Jury nullification in the United States has its origins in colonial America under British law. In the United States, jury nullification occurs when a jury in a criminal case reaches a verdict contrary to the weight of evidence, sometimes because of a disagreement with the relevant law. The American jury draws its power of nullification from its right to render a general verdict in criminal trials, the inability of criminal courts to direct a verdict no matter how strong the evidence, the Fifth Amendment's Double Jeopardy Clause, which prohibits the appeal of an acquittal, and the fact that jurors cannot be punished for the verdict they return.
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.
There are three types of juries in the United States: criminal grand juries, criminal petit juries, and civil juries. In the United States Constitution, juries are mentioned in Article Three and the Fifth, the Sixth, and the Seventh Amendments. Juries are not available in courts of American Samoa established pursuant to the Constitution of American Samoa.
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.
Wainwright vs. Witt, 470 U.S. 1039 (1985), was a U.S. Supreme Court case concerning a criminal defendant, Johnny Paul Witt, who argued that his Sixth and Fourteenth Amendment rights were violated when he was sentenced to death for first degree murder by the state of Florida. He argued that the trial court had unconstitutionally hand-picked a jury during the voir dire process. This was because certain people were excused from the jury because they admitted pre-trial, that their decision of guilty or not guilty toward capital punishment would be swayed due to personal or religious beliefs.
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.
The United States Constitution contains several provisions regarding the law of criminal procedure.
People v. Newton, 8 Cal. App. 3d 359, was a controversial appeal arising from the voluntary manslaughter conviction of Huey P. Newton, the reputed co-founder of the Black Panther Party for Self Defense. The California Court of Appeal reversed Newton's conviction due to prejudicial error stemming from the trial court's failure to instruct the jury as to the possibility of involuntary unconsciousness as a complete defense to the charges. Though Newton's attorney arguably withdrew the defense at trial, the Court nonetheless held that the failure to instruct violated Newton's constitutional right to have the jury determine all material issues based on the evidence. This case stands for the proposition that trial courts have an affirmative duty to instruct juries as to a defense of involuntary unconsciousness where there exists evidence that may support that conclusion.
Ham v. South Carolina, 409 U.S. 524 (1973), was a United States Supreme Court decision concerning examinations of prospective jurors during voir dire. The Court held that the trial court's failure to "have the jurors interrogated on the issue of racial bias" violated the petitioner's due process right under the Fourteenth Amendment. This right does not extend to any question of bias, but it does not preclude questions of relevant biases.
Simmons v. South Carolina, 512 U.S. 154 (1994), is a United States Supreme Court case holding that, where a capital defendant's future dangerousness is at issue, and the only alternative sentence available is life imprisonment without the possibility of parole, the sentencing jury must be informed that the defendant is ineligible for parole.
Carter v. Kentucky was a case in which the U.S. Supreme Court held that trial judges in criminal proceedings must, upon proper request of the defendant, inform the jury of his right against self-incrimination, and that its execution may not be used against him.
