Whether the imposition and carrying out of the death sentences in these three cases constituted cruel and unusual punishment under the Eighth and Fourteenth Amendments.
Holding
Yes. The Court reversed the judgments insofar as they left the death sentences in place and remanded for further proceedings.
Reasoning
The per curiam judgment gave no single rationale. Five Justices agreed that these death sentences could not stand, but they supplied separate concurring opinions grounded in different theories. Thus, Furman produced a controlling result rather than one majority opinion explaining every aspect of the Eighth Amendment rule.
Justices Stewart and White supplied the narrowest and most practically controlling ground. They concluded that the statutes gave juries or judges essentially unguided discretion to choose which murderers and rapists would live and which would die, while death was imposed only rarely. That combination made the selection of those sentenced to death arbitrary, capricious, and constitutionally intolerable.
The Court did not hold, by a majority, that capital punishment was unconstitutional in every circumstance. Justices Brennan and Marshall would have held that death itself was always cruel and unusual, but other Justices in the judgment expressly reserved the possibility that a different capital-sentencing system, such as one with meaningful standards or a mandatory penalty for narrowly defined crimes, might survive Eighth Amendment review.
