Death Penalty
Congress, as well as any state legislature, may prescribe the death penalty, also known as capital punishment, for capital offenses. The Supreme Court has ruled that the death penalty does not violate the Eighth Amendment's ban on cruel and unusual punishment, but the Eighth Amendment does shape certain procedural aspects regarding when a jury may use the death penalty and how it must be carried out. Because of the Fourteenth Amendment's Due Process of Law Clause, the Eighth Amendment applies against the states, as well as the federal government.
Eighth Amendment analysis requires that courts consider the evolving standards of decency to determine if a particular punishment constitutes a cruel or unusual punishment. When considering evolving standards of decency, courts look for objective factors to show a change in community standards and also make independent evaluations about whether the statute in question is reasonable.
