Whether excluding prospective jurors for cause merely because they voice general objections to capital punishment or conscientious or religious scruples against it permits the resulting jury constitutionally to impose a death sentence.
Holding
No. A death sentence cannot be carried out when the sentencing jury was selected by excluding veniremembers solely for general opposition to capital punishment or for conscientious or religious scruples against its infliction.
Reasoning
The Court drew a critical line between general reservations about capital punishment and an inability to perform a juror's legal duty. A State may exclude a person whose views would prevent an impartial decision on guilt, and it may exclude a person who makes unmistakably clear that he would automatically vote against death regardless of the evidence. But Illinois excluded far more broadly, often without determining whether a prospective juror would in fact refuse to consider death in the particular case.
Illinois gave the jury broad discretion to choose between life imprisonment and death. In making that moral and discretionary choice, a juror's general views about capital punishment inevitably matter. A person who opposes the death penalty may nevertheless consider every lawful sentencing option, follow the instructions, and make the discretionary judgment the State assigned to the jury.
A capital jury must serve as a link between contemporary community values and the criminal-justice system. By systematically removing everyone with doubts or scruples about capital punishment, Illinois did not create a neutral jury capable of considering both sentencing alternatives. It created a tribunal unusually willing to impose death and therefore unable to express the community's conscience on the ultimate life-or-death decision.
Due process does not allow a State to entrust guilt to a tribunal organized to convict. By the same principle, it cannot entrust the decision whether a defendant lives or dies to a tribunal deliberately organized to return death verdicts. Illinois's selection procedure deliberately tipped the scales toward death and denied Witherspoon the procedural fairness required by the Sixth and Fourteenth Amendments.
