State v. McKoy, 494 U.S. 433 (1990)
State v. McKoy is a pivotal case decided by the United States Supreme Court that addresses the intricacies of jury instructions in the penalty phase of capital trials.
Does a jury instruction requiring unanimity for consideration of mitigating circumstances in a capital sentencing procedure violate the Eighth Amendment?
The Eighth Amendment prohibits cruel and unusual punishments, which includes ensuring that capital sentencing procedures allow for consideration of mitigating evidence that may warrant a sentence less than death.
Yes, the Supreme Court held that the North Carolina jury instruction at issue was unconstitutional. The requirement for unanimity in considering mitigating circumstances improperly limited the jurors' ability to individually engage with the evidence and make an independent moral judgment on the appropriate sentence.
State v. McKoy is a landmark decision because it reinforces the importance of individualized sentencing in capital cases. For law students, it highlights the intricate relationship between procedural requirements and constitutional protections under the Eighth Amendment. The ruling underscores the necessity of ensuring fairness and jurors' discretion when considering life-and-death decisions, which is a critical aspect of criminal procedure and constitutional law.
