Eighth Amendment:
Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.
In Trop v. Dulles, the majority refused to consider the death penalty as an index of the constitutional limit on punishment. Whatever the arguments may be against capital punishment . . . the death penalty has been employed throughout our history, and, in a day when it is still widely accepted, it cannot be said to violate the constitutional concept of cruelty.
1 But a coalition of civil rights and civil liberties organizations mounted a campaign against the death penalty in the 1960s, and the Court eventually confronted the issues involved. The answers were not, it is fair to say, consistent.
A series of cases testing the means by which the death penalty was imposed2 culminated in what appeared to be a decisive rejection of the attack in McGautha v. California.3
The Court added a fourth major guideline in 2002, holding that the Sixth Amendment right to trial by jury comprehends the right to have a jury make factual determinations on which a sentencing increase is based.4 This means that capital sentencing schemes are unconstitutional if judges are allowed to make factual findings as to the existence of aggravating circumstances that are prerequisites for imposition of a death sentence.
