A jury is a sworn body of people (jurors) convened to render an impartial verdict officially submitted to them by a court, or to set a penalty or judgment. Juries developed in England during the Middle Ages and are a hallmark of the Anglo common law legal system. They are still commonly used today in the United Kingdom, the United States, Canada, India, Australia, and other countries whose legal systems are descended from English and later British legal traditions.
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.
The Trenton Six is the group name for six African-American defendants tried for murder of an elderly white shopkeeper in January 1948 in Trenton, New Jersey. The six young men were convicted in August 1948 by an all-white jury of the murder and sentenced to death.
People v. LaValle, 3 N.Y.3d 88 (2004), was a landmark decision by the New York Court of Appeals, the highest court in the U.S. state of New York, in which the court ruled that the state's death penalty statute was unconstitutional because of the statute's direction on how the jury was to be instructed in case of deadlock. New York has since been without the death penalty, as the law has not been amended.

When he entered Louisiana State Prison (Angola), he was the youngest person on death row.
In criminal law, a mitigating factor, also known as an extenuating circumstance, is any information or evidence presented to the court regarding the defendant or the circumstances of the crime that might result in reduced charges or a lesser sentence. Unlike a legal defense, the presentation of mitigating factors will not result in the acquittal of a defendant. The opposite of a mitigating factor is an aggravating factor.

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.

Tennard v. Dretke, 542 U.S. 274 (2004), was a United States Supreme Court case in which the court was asked whether evidence of the defendant's low IQ in a death penalty trial had been adequately presented to the jury for full consideration in the penalty phase of his trial. The Supreme Court held that not considering a defendant's low IQ would breach his Eighth Amendment rights and constitute a cruel and unusual punishment.
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.
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.

Payne v. Tennessee, 501 U.S. 808 (1991), was a United States Supreme Court case which held that testimony in the form of a victim impact statement is admissible during the sentencing phase of a trial and, in death penalty cases, does not violate the Cruel and Unusual Punishment Clause of the Eighth Amendment. Payne narrowed two of the Courts' precedents: Booth v. Maryland (1987) and South Carolina v. Gathers (1989).
Rolando Cruz is an American man known for having been wrongfully convicted and sentenced to death, along with co-defendant Alejandro Hernandez, for the 1983 kidnapping, rape, and murder of 10-year-old Jeanine Nicarico in DuPage County, Illinois.

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.

Deck v. Missouri, 544 U.S. 622 (2005), was a United States Supreme Court case that dealt with the constitutionality of shackling a prisoner during the sentencing phase of a trial.

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).
Dawson v. Delaware, 503 U.S. 159 (1992), was a United States Supreme Court decision that ruled that a person's rights of association and due process, as granted under the First Amendment and Fourteenth Amendment of the United States Constitution, cannot be infringed upon if such an association has no bearing on the case at hand.
Kansas v. Carr, 577 U.S. ___ (2016), was a case in which the Supreme Court of the United States clarified several procedures for sentencing defendants in capital cases. Specifically, the Court held that judges are not required to affirmatively instruct juries about the burden of proof for establishing mitigating evidence, and that joint trials of capital defendants "are often preferable when the joined defendants’ criminal conduct arises out of a single chain of events". This case included the last majority opinion written by Justice Antonin Scalia before his death in February 2016.
