States and Capital Punishment


Capital punishment is currently authorized in 29 states, by the federal government and the U.S. military. In recent years, New Mexico (2009), Illinois (2011), Connecticut (2012), Maryland (2013) and New Hampshire (2019) have legislatively abolished the death penalty, replacing it with a sentence of life imprisonment with no possibility for parole. The Nebraska Legislature also abolished capital punishment in 2015, but it was reinstated by a statewide vote in 2016. Additionally, courts in Washington and Delaware recently ruled that the states' capital punishment laws are unconstitutional. States across the country will continue to debate its fairness, reliability and cost of implementation.

Methods of Execution

Lethal injection is currently the primary method of execution in all 29 states that have capital punishment. Texas was the first state to use the method, in 1982.

Sixteen states also have a secondary method of execution authorized by statute. Laws in Alabama, Arkansas, Mississippi, New Hampshire, Oklahoma, South Carolina, Tennessee, Utah and Wyoming provide a secondary option if lethal injection is found to be unconstitutional and/or unavailable. Arizona*, Kentucky, Tennessee and Utah all have a choice of secondary methods for offenders who were sentenced before the introduction of lethal injection. And Alabama, California*, Florida, Missouri, South Carolina, Virginia and Washington have other methods that are available if the offender requests an alternative. Secondary methods of execution include electrocution, lethal gas, hanging, nitrogen hypoxia, and firing squad.

*See case law in each state to determine the constitutionality of secondary methods. For example, see La Grand v. Stewart, 173 F.3d 1144 (1999).

Significant Litigation

Over the past decade, several U.S. Supreme Court rulings have narrowed the death penalty’s application in the states. The court has abolished the death penalty for mentally disabled offenders (Atkins v. Virginia, 2002), juvenile offenders (Roper v. Simmons, 2005), and for those convicted of raping a child where death was not the intended or actual result (Kennedy v. Louisiana, 2008) – each ruling states that the execution of such individuals is unconstitutional, violating cruel and unusual punishment. In addition, the court has required that juries and not judges find facts that make a defendant eligible for capital punishment (Ring v. Arizona, 2002), and impose a sentence of death (Hurst v. Florida, 2016).

State courts have also had an impact. The Delaware Supreme Court issued a decision on August 2, 2016 striking down the state’s death penalty statute, ruling that it violated the Sixth Amendment as interpreted by the U.S. Supreme Court decision Hurst v. Florida. The Delaware attorney general announced that he will not appeal the decision of the state court and legislation would be required to reinstate capital punishment in the state. The Washington Supreme Court also recently struck down the state's death penalty on October 11, 2018. This was the fourth time the court has ruled the state's capital punishment law unconstitutional, calling it "invalid because it is imposed in an arbitrary and racially biased manner."
