Death Penalty

death penalty: an overview



Proportionality Requirement


In Furman v. Georgia, 408 U.S. 238, (1972), the Court invalidated existing death penalty laws because they constituted cruel and unusual punishment in violation of the Eighth Amendment.  The Court reasoned that the laws resulted in a disproportionate application of the death penalty, specifically discriminating against the poor and minorities.  The Court also reasoned that the existing laws terminated life in exchange for marginal contributions to society.

In Gregg v. Georgia, 428 U.S. 153, (1976), the Court refused to expand Furman.  The Court held the death penalty was not per se unconstitutional as it could serve the social purposes of retribution and deterrence.  Specifically, the Court upheld Georgia’s new capital sentencing procedures, reasoning that the Georgia rules reduced the problem of arbitrary application as seen in earlier statutes.

The death penalty, however, remains limited to capital offenses. In the landmark case of Coker v. Georgia, 433 U.S. 584, (1977), the Supreme Court ruled that a state cannot apply the death penalty to the crime of raping an adult woman because it violates the proportionality requirement. The Court came to this conclusion by considering objective indicia of the nation's attitude toward the death penalty in rape cases. At the time only a few states allowed for executions of convicted rapists.

Twenty-one years later, in Kennedy v. Louisiana, 554 U.S. 407, (2008), the Supreme Court extended its ruling in Coker, holding that the penalty is categorically unavailable for cases of child rape in which the victim lives. Because only six states in the country permitted execution as a penalty for child rape, the Supreme Court found the national consensus to hold its use in these cases as disproportionate.

Principle of Individualized Sentencing

To impose a death sentence, the jury must be guided by the particular circumstances of the criminal, and the court must have conducted an individualized sentencing process. In Ring v. Arizona, 536 U.S. 584, (2002) the Supreme Court held that it is unconstitutional for "a sentencing judge, sitting without a jury, to find an aggravating circumstance necessary for imposition of the death penalty." An aggravating factor is any fact or circumstance that increases the culpability for a criminal act.

The Supreme Court further refined the requirement of "a finding of aggravating factors" in Brown v. Sanders546 U.S. 212 (2006). For cases in which an appellate court rules a sentencing factor invalid, the Court ruled that the sentence imposed becomes unconstitutional unless the jury found some other aggravating factor that encompasses the same facts and circumstances as the invalid factor.

Kansas v. Marsh, 548 U.S. 163, (2006)offered yet another clarification to the principle of individualized sentencing jurisprudence. After Marsh, states may impose the death penalty when the jury finds any aggravating and mitigating factors to be equally weighted, without violating the principle of individualized sentencing.

Method of Execution


State courts and lower federal courts have refused to strike down hanging and electrocution as impermissible methods of execution; however, the U.S. Supreme Court did not take up a method of execution case for 117 years until Baze v. Rees, 553. U.S 35, (2008). Baze held that lethal injection did not constitute a cruel and unusual punishment. This case resolved a controversial issue in light of recent evidence that a lethal injection's three-drug combination fails to alleviate pain and prevents the criminal from signaling such pain because of paralysis inducement.

Classes of Persons Not Eligible for the Death Penalty

More recently, in Atkins v. Virginia, 536 U.S. 304, (2002), the Supreme Court determined that executing mentally retarded criminals violates the ban on "cruel and unusual punishments" because their mental handicap lessens the severity of the crime and therefore renders the extraordinary penalty of death as disproportionately severe. However, in Bobby v. Bies, 556 U.S. 825, (2009), the Court held that states may conduct hearings to reconsider the mental capacity of death row inmates who were labeled mentally retarded before the Court decided Atkins, because before Atkins, states had little incentive to aggressively investigate retardation claims.

In Roper v. Simmons, 543 U.S. 551, (2005), the Supreme Court invalidated the death penalty for all juvenile offenders. The majority opinion pointed to teenagers' lack of maturity and responsibility, greater vulnerability to negative influences, and incomplete character development. The Court concluded that juvenile offenders assume diminished culpability for their crimes.
