Overview of Capital Punishment Under State and Federal Law 4
law required the panel of judges to reach a unanimous verdict on sentencing; otherwise, the
court was required to sentence the defendant to life in prison.
This was Colorado law at the
time of the U.S. Supreme Court’s 2002 decision in Ring v. Arizona, in which the Court ruled that
the Sixth Amendment to the U.S. Constitution requires that aggravating circumstances
necessary for imposition of the death penalty be found by a jury, not a judge.
This ruling
prompted states, including Colorado, to change their laws to require that a jury make sentencing
decisions in death penalty cases.
Following the Ring decision, Colorado Governor Bill Owens called a special legislative
session.
The General Assembly convened on July 8, 2002, and amended Colorado law to
again require the trial jury to perform sentencing.
Under this law, when the jury cannot reach a
unanimous sentencing decision, the court is required to sentence the defendant to life in prison.
This remains current Colorado law.
In 2016, the Court reaffirmed Ring, and overturned Florida’s death penalty sentencing
scheme, which required the judge alone to find the existence of an aggravating circumstance
necessary to impose a death penalty.
Court decisions and Colorado law concerning minors and persons with mental
disabilities. In addition to cases involving death penalty sentencing procedures, the
U.S. Supreme Court also hears cases that consider the application of the death penalty. In
2005, the Court held that the U.S. Constitution prohibits the execution of offenders who were
sentenced to death for a crime committed while the offender was under the age of 18.
In
2002, the Court held that the U.S. Constitution restricts states’ power to sentence an
intellectually disabled offender to death.
Under current Colorado law, an offender convicted as an adult of a class 1 felony that was
committed while the offender was a juvenile, or an offender convicted of a class 1 felony who is
determined to be “mentally retarded,” is not subject to the death penalty, and is instead
sentenced to life imprisonment with the possibility of parole after 40 years.
Recent issues concerning lethal injection. Each jurisdiction that permits capital
punishment, including Colorado, uses lethal injection as its primary method of carrying out the
death penalty.
The U.S. Supreme Court has heard challenges to the procedures used for
lethal injection. In 2008, the Court upheld the use of lethal injection as a means of execution in
Baze v. Rees.
In Baze, the Court specifically upheld Kentucky’s use of lethal injection against
claims that the procedure could cause severe pain to the executed offender if administered
improperly. The Court found that the first drug in a three-drug combination used for injection,
sodium thiopental, was sufficient to mitigate the pain suffered by the offender.

During the special session, the General Assembly enacted House Bill 02S-1005, which amended Section 16-11-103 (2)(d), C.R.S.
(2001), effective July 12, 2002. On October 1, 2002, that amended section was relocated to Section 18-1.3-1201 (2)(d), C.R.S.
(2002) in accordance with a bill passed during the 2002 regular session. Section 12 of HB 02S-1005 stated the General Assembly’s
intent that there be no hiatus in the imposition of the death penalty as a result of the decision in Ring v. Arizona.
Hurst v. Florida, 136 S.Ct. 616 (2016). Colorado law permits a defendant to waive the right to a jury and have guilt and sentencing
decisions made by a judge. These provisions have not been reviewed by a court in light of the U.S. Supreme Court’s Hurst
decision.
Roper v. Simmons, 543 U.S. 551, 578 (2005).
Atkins v. Virginia, 536, U.S. 304, 321 (2002), internal quotations omitted. A later case, Hall v. Florida, 134 S. Ct. 1986 (2014),
explored the constitutionality of Florida’s method to determine when an offender should be considered intellectually disabled.
Section 18-1.3-401 (4)(b), C.R.S. (juveniles); Section 18-1.3-1103, C.R.S. (“mentally retarded” defendants).
Information on state and federal methods of execution is available in Appendix D. Colorado adopted lethal injection as the means
for execution in 1988.
