Furman v. Georgia, 408 U.S. 238 (1972), was a criminal case in which the United States Supreme Court invalidated all death penalty schemes in the United States in a 5–4 decision, with each member of the majority writing a separate opinion. Following Furman, in order to reinstate the death penalty, states had to at least remove arbitrary and discriminatory effects in order to satisfy the Eighth Amendment to the U.S. Constitution.
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.
McCleskey v. Kemp, 481 U.S. 279 (1987), is a United States Supreme Court case, in which the death penalty sentencing of Warren McCleskey for armed robbery and murder was upheld. The Court said the "racially disproportionate impact" in the Georgia death penalty indicated by a comprehensive scientific study was not enough to mitigate a death penalty determination without showing a "racially discriminatory purpose." McCleskey has been described as the “most far-reaching post-Gregg challenge to capital sentencing.”
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.
Wrongful execution is a miscarriage of justice occurring when an innocent person is put to death by capital punishment. Cases of wrongful execution are cited as an argument by opponents of capital punishment, while proponents say that the argument of innocence concerns the credibility of the justice system as a whole and does not solely undermine the use of the death penalty.
Stanford v. Kentucky, 492 U.S. 361 (1989), was a United States Supreme Court case that sanctioned the imposition of the death penalty on offenders who were at least 16 years of age at the time of the crime. This decision came one year after Thompson v. Oklahoma, in which the Court had held that a 15-year-old offender could not be executed because to do so would constitute cruel and unusual punishment. In 2003, the Governor of Kentucky Paul E. Patton commuted the death sentence of Kevin Stanford, an action followed by the Supreme Court two years later in Roper v. Simmons overruling Stanford and holding that all juvenile offenders are exempt from the death penalty.
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.
Ford v. Wainwright, 477 U.S. 399 (1986), was a landmark U.S. Supreme Court case that upheld the common law rule that the insane cannot be executed; therefore the petitioner is entitled to a competency evaluation and to an evidentiary hearing in court on the question of their competency to be executed.

Barefoot v. Estelle, 463 U.S. 880 (1983), is a United States Supreme Court case. The Court ruled on the admissibility of clinical opinions given by two psychiatrists hired by the prosecution in answer to hypothetical questions regarding the defendant's future dangerousness and the likelihood that he would present a continuing threat to society in this Texas death penalty case. The American Psychiatric Association submitted an amicus curiae brief in support of the defendant's position that such testimony should be inadmissible and urging curtailment of psychiatric testimony regarding future dangerousness and a prohibition of such testimony based on hypothetical data.
Schlup v. Delo, 513 U.S. 298 (1995), was a case in which the United States Supreme Court expanded the ability to reopen a case in light of new evidence of innocence.
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).
The Supreme Court of the United States handed down nineteen per curiam opinions during its 2009 term, which began on October 5, 2009, and concluded October 3, 2010.
Leal Garcia v. Texas, 564 U.S. 940 (2011), was a ruling in which the Supreme Court of the United States denied Humberto Leal García's application for stay of execution and application for writ of habeas corpus. Leal was subsequently executed by lethal injection. The central issue was not Leal's guilt, but rather that he was not notified of his right to call his consulate as required by international law. The Court did not stay the execution because Congress had never enacted legislation regarding this provision of international law. The ruling attracted a great deal of commentary and Leal's case was supported by attorneys specializing in international law and several former United States diplomats.
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. In a 7–2 opinion delivered by Justice Breyer, the court held that it is against due process, a right prescribed by the 5th and 14th Amendments, to shackle a defendant in the sentencing portion of a trial unless the shackling relates to a specific defendant and certain state interests.
Vasquez v. Hillery, 474 U.S. 254 (1986), is a United States Supreme Court case, which held that a defendant's conviction must be reversed if members of their race were systematically excluded from the grand jury that indicted them, even if they were convicted following an otherwise fair trial.
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.
Whitmore v. Arkansas, 495 U.S. 149 (1990), is a U.S. Supreme Court Case that held that the Eighth and the Fourteenth Amendments do not require mandatory appellate review of death penalty cases and that individuals cannot file cases as a next friend without a prior relationship to the appellant.
McQuiggin v. Perkins, 569 U.S. 383 (2013), was a United States Supreme Court case in which the Court held that actual innocence, if proven, is sufficient to circumvent the one-year statute of limitations for petitioners to appeal their conviction enacted within the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA).
Ybarra v. Illinois was a decision of the U.S. Supreme Court which ruled that a warrant can not be used to search an unnamed individual unless the warrant mentions that unnamed parties are involved or exigent circumstances are shown to exist.
