Summary

Background

A man convicted of murder in Mississippi was sentenced to death. The Mississippi Supreme Court affirmed his sentence after the trial judge instructed the jury to consider whether the killing was "especially heinous, atrocious, or cruel," using definitions the judge supplied. The defendant argued that that instruction was too vague to lawfully support a death sentence.

Reasoning

The Court focused on whether the trial court’s definitions gave the jury enough guidance to use the aggravating factor. The per curiam opinion says the limiting instruction—defining "heinous," "atrocious," and "cruel" with phrases like "extremely wicked or shockingly evil"—was not constitutionally sufficient. The Court relied on its earlier decisions showing similar language could be read to cover almost every murder. Because the jury could have relied on those vague descriptions, the Court reversed the state court’s reliance on that factor and remanded the case for further consideration in light of related decisions.

Real world impact

The ruling prevents this particular aggravating instruction from being used to justify the death sentence as it stood, and requires the state courts to reconsider the sentence without relying on that vague factor. The decision does not itself resolve every question about the defendant’s sentence; the case is sent back so the Mississippi courts can determine what happens next.

Dissents or concurrances

Justice Marshall agreed with the reversal and wrote separately to explain that the trial court’s supposedly limiting definitions were essentially the same deficient language previously rejected by the Court.
