In the United States, capital punishment is a legal penalty in 27 states, throughout the country at the federal level, and in American Samoa. It is also a legal penalty for some military offenses. Capital punishment has been abolished in 23 states and in the federal capital, Washington, D.C. It is usually applied for only the most serious crimes, such as aggravated murder. Although it is a legal penalty in 27 states, 19 of them have authority to execute death sentences, with the other 8, as well as the federal government and military, subject to moratoriums.
Capital punishment is not allowed to be carried out in the U.S. state of California, due to both a standing 2006 federal court order against the practice and a 2019 moratorium on executions ordered by Governor Gavin Newsom. The litigation resulting in the court order has been on hold since the promulgation of the moratorium. Should the moratorium end and the freeze concluded, executions could resume under the current state law.
Gregg v. Georgia, Proffitt v. Florida, Jurek v. Texas, Woodson v. North Carolina, and Roberts v. Louisiana, 428 U.S. 153 (1976), is a landmark decision of the U.S. Supreme Court. It reaffirmed the Court's acceptance of the use of the death penalty in the United States, upholding, in particular, the death sentence imposed on Troy Leon Gregg. The set of cases is referred to by a leading scholar as the July 2 Cases, and elsewhere referred to by the lead case Gregg. The court set forth the two main features that capital sentencing procedures must employ in order to comply with the Eighth Amendment ban on "cruel and unusual punishments". The decision essentially ended the de facto moratorium on the death penalty imposed by the Court in its 1972 decision in Furman v. Georgia (1972). Justice Brennan's dissent famously argued that "The calculated killing of a human being by the State involves, by its very nature, a denial of the executed person's humanity ... An executed person has indeed 'lost the right to have rights.'"
Ring v. Arizona, 536 U.S. 584 (2002), was a case in which the United States Supreme Court applied the rule of Apprendi v. New Jersey to capital sentencing schemes, holding that the Sixth Amendment requires a jury to find the aggravating factors necessary for imposing the death penalty. Ring overruled a portion of Walton v. Arizona, which had rejected that contention.
Schriro v. Summerlin, 542 U.S. 348 (2004), was a case in which the United States Supreme Court held that a requirement that a different Supreme Court decision requiring the jury rather than the judge to find aggravating factors would not be applied retroactively.
Hill v. McDonough, 547 U.S. 573 (2006), was a United States Supreme Court case challenging the use of lethal injection as a form of execution in the state of Florida. The Court ruled unanimously that a challenge to the method of execution as violating the Eighth Amendment to the United States Constitution properly raised a claim under 42 U.S.C. § 1983, which provides a cause of action for civil rights violations, rather than under the habeas corpus provisions. Accordingly, that the prisoner had previously sought habeas relief could not bar the present challenge.
Kansas v. Marsh, 548 U.S. 163 (2006), is a United States Supreme Court case in which the Court held that a Kansas death penalty statute was consistent with the United States Constitution. The statute in question provided for a death sentence when the aggravating factors and mitigating factors were of equal weight.
Walton v. Arizona, 497 U.S. 639 (1990), was a United States Supreme Court case that upheld two important aspects of the capital sentencing scheme in Arizona—judicial sentencing and the aggravating factor "especially heinous, cruel, or depraved"—as not unconstitutionally vague. The Court overruled the first of these holdings in Ring v. Arizona, 536 U.S. 584 (2002). The second of these holdings has yet to be overturned.
Cunningham v. California, 549 U.S. 270 (2007), is a decision by the Supreme Court of the United States in which the Court held, 6–3, that the sentencing standard set forward in Apprendi v. New Jersey (2000) applies to California's determinate sentencing law.
Jones v. United States, 526 U.S. 227 (1999), is a United States Supreme Court case interpreting the federal carjacking statute, 18 U.S.C. § 2119, to set forth three distinct crimes, each with distinct elements. The Court drew this conclusion from the structure of the statute, under which two subsections provided for additional punishment if the defendant inflicts more serious harm. The Court also distinguished Almendarez-Torres v. United States, 523 U.S. 224 (1998), because that case allowed for sentencing enhancement based on a prior conviction.
Godfrey v. Georgia, 446 U.S. 420 (1980), was a United States Supreme Court case in which the Court held that a death sentence could not be granted for a murder when the only aggravating factor was that the murder was found to be "outrageously or wantonly vile."

Smith v. Spisak, 558 U.S. 139 (2010), was a United States Supreme Court decision on the applicability of the Antiterrorism and Effective Death Penalty Act of 1996. It further examined issues of previous court decisions on jury instructions and the effectiveness of counsel.
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.
Capital punishment is currently a legal penalty in the U.S. state of Kansas, although it has not been used since 1965.
Lockhart v. Fretwell, 506 U.S. 364 (1993), is a decision of the United States Supreme Court which held that failure to make an objection under Collins v. Lockhart did not constitute undue prejudice required by Strickland v. Washington, because the error did not cause a fundamentally unfair trial, as opposed to merely a different outcome of the case.
Cullen v. Pinholster, 563 U.S. 170, is a 2011 United States Supreme Court case concerning evidentiary development in federal habeas corpus proceedings. Oral arguments in the case took place on November 9, 2010, and the Supreme Court issued its decision on April 4, 2011. The Supreme Court held 5–4 that only evidence originally presented before the state court in which the claim was originally adjudicated on the merits could be presented when raising a claim under 28 U.S.C. § 2254(d)(1), and that evidence from a federal habeas court could not be presented in such proceedings. It also held that the convicted murderer Scott Pinholster, the respondent in the case, was not entitled to the habeas relief he had been granted by the United States Court of Appeals for the Ninth Circuit.
