Facts

Sidney Gleason was sentenced to death after a jury found aggravating circumstances beyond a reasonable doubt for murders committed to cover up a robbery. Reginald and Jonathan Carr were jointly sentenced to death for four murders arising from the Wichita Massacre, after the jury heard aggravating evidence from the guilt phase and separate mitigation cases for each brother. In both cases, the juries were instructed that the State had to prove aggravating circumstances and that they outweighed any mitigating circumstances beyond a reasonable doubt, while mitigating circumstances were described as circumstances 'found to exist.' The Kansas Supreme Court concluded that the juries should also have been affirmatively told that mitigating circumstances need not be proved beyond a reasonable doubt, and it further concluded that the Carrs' joint sentencing proceeding should have been severed.

Issue

Whether the Eighth Amendment requires a capital-sentencing court to instruct the jury that mitigating circumstances need not be proved beyond a reasonable doubt. Whether the Constitution required severance of the Carr brothers' joint capital-sentencing proceeding because each brother's mitigation evidence allegedly prejudiced the other.

Rule

The Eighth Amendment does not require capital-sentencing courts to instruct juries that mitigating circumstances need not be proved beyond a reasonable doubt. Ambiguity in capital-sentencing instructions is unconstitutional only if there is a reasonable likelihood that the jury applied the instruction in a way that prevented consideration of constitutionally relevant mitigating evidence. When the complaint is that evidence admitted in a joint capital-sentencing proceeding was improperly prejudicial, the governing question is whether the evidence so infected the sentencing proceeding with unfairness as to render the death sentence a denial of due process.

In a capital sentencing hearing in Tulsa, the judge instructed the jury that the prosecution had to prove each aggravating circumstance beyond a reasonable doubt and had to prove beyond a reasonable doubt that the aggravators were not outweighed by any mitigating circumstances found to exist. The judge also told jurors they could consider any mitigating circumstance each juror found to exist, but did not expressly say mitigating circumstances need not be proved beyond a reasonable doubt.

If the defendant argues the Eighth Amendment was violated because the jury was not affirmatively told that mitigating circumstances need not be proved beyond a reasonable doubt, how should a reviewing court rule?

Explanation. The majority held that the Eighth Amendment does not require capital-sentencing courts to instruct juries that mitigating circumstances need not be proved beyond a reasonable doubt. The key question is whether there is a reasonable likelihood the jury applied the instructions to prevent consideration of constitutionally relevant mitigating evidence. Here, as in the case, the instructions place the beyond-a-reasonable-doubt burden on aggravators and the weighing determination, while mitigation need only be found to exist.
