The Eighth Amendment to the United States Constitution protects against imposing excessive bail, excessive fines, or cruel and unusual punishments. This amendment was adopted on December 15, 1791, along with the rest of the United States Bill of Rights. The amendment serves as a limitation upon the federal government to impose unduly harsh penalties on criminal defendants before and after a conviction. This limitation applies equally to the price for obtaining pretrial release and the punishment for crime after conviction. The phrases in this amendment originated in the English Bill of Rights of 1689.
Capital punishment is a legal penalty in the U.S. state of Indiana. The last man executed in the state, excluding federal executions at Terre Haute, was the murderer Matthew Wrinkles in 2009.
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 case 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 408 U.S. 238 (1972).
Roper v. Simmons, 543 U.S. 551 (2005), is a landmark decision by the Supreme Court of the United States in which the Court held that it is unconstitutional to impose capital punishment for crimes committed while under the age of 18. The 5–4 decision overruled Stanford v. Kentucky, in which the court had upheld execution of offenders at or above age 16, and overturned statutes in 25 states.
Oregon v. Guzek, 546 U.S. 517 (2006), was a decision by the Supreme Court of the United States, which ruled that the Eighth Amendment to the United States Constitution does not grant criminal defendants facing the death penalty the right to introduce new evidence of their innocence during sentencing that was not introduced during trial. Accordingly, states could constitutionally exclude such evidence from the sentencing phase of a capital trial.
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 then abandoned the death penalty, as the law has not been amended.
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.
Kennedy v. Louisiana, 554 U.S. 407 (2008), is a landmark decision by the Supreme Court of the United States which held that the Eighth Amendment's Cruel and Unusual Punishments Clause prohibits the imposition of the death penalty for a crime in which the victim did not die and the victim's death was not intended.
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.
Penry v. Johnson, 532 U.S. 782 (2001), is a United States Supreme Court case which concerned whether instructions given to a Texas jury were constitutionally adequate to emphasize the mitigating factors in sentencing of defendants who are intellectually disabled The Texas courts had determined the sentencing instructions were consistent with prior Supreme Court jurisprudence, but the Court in a divided decision reversed, finding the sentencing instructions insufficient. This was the second time Penry's case made it to the Supreme Court.
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.
The United States Constitution contains several provisions related to criminal sentencing.
Glossip v. Gross, 576 U.S. 863 (2015), was a United States Supreme Court case in which the Court held, 5–4, that lethal injections using midazolam to kill prisoners convicted of capital crimes do not constitute cruel and unusual punishment under the Eighth Amendment to the United States Constitution. The Court found that condemned prisoners can only challenge their method of execution after providing a known and available alternative method.
Montgomery v. Louisiana, 577 U.S. ___ (2016), was a United States Supreme Court case in which the Court held that its previous ruling in Miller v. Alabama (2012), that a mandatory life sentence without parole should not apply to persons convicted of murder committed as juveniles, should be applied retroactively. This decision potentially affects up to 2,300 cases nationwide.
The Supreme Court of the United States handed down eighteen per curiam opinions during its 2015 term, which began October 5, 2015 and concluded October 2, 2016.
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.
Blueford v. Arkansas, 566 U.S. 599 (2012), was a decision of the Supreme Court of the United States that clarified the limits of the Double Jeopardy Clause. The Supreme Court held that the Double Jeopardy Clause does not bar retrial of counts that a jury had previously unanimously voted to acquit on, when a mistrial is declared after the jury deadlocked on a lesser included offense.
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.
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.
Sumner v. Shuman, 483 U.S. 66 (1987), was a case in which the Supreme Court of the United States held that a mandatory death penalty for a prison inmate who is convicted of murder while serving a life sentence without possibility of parole is unconstitutional. The decision in this case was a significant development in the Court's capital punishment jurisprudence, further clarifying the limits on the application of the death penalty in the United States.
