sentences:  In a 6-3 decision, Justice White wrote for the majority that a defendant facing the death penalty may challenge for cause a prospective juror who would automatically vote to impose the death penalty in every case.Just as a juror who is unalterably opposed to the imposition of the death penalty must be excluded because he or she cannot conscientiously fulfill the oath to follow the law and the instructions to the jury pursuant thereto, so should one who would automatically vote to impose the death penalty be excluded for the same reason.Such a juror, he emphasized, would lack the qualities of impartiality and indifference required by due process.
