What it's about

The Supreme Court overturned the Kansas Supreme Court’s ruling in Carr’s case and sent it back to that court (remanded).

The Kansas Supreme Court had earlier wiped out Carr's death sentence (vacated it) because of constitutional errors in the penalty phase.

The Supreme Court's opinion also covered two other Kansas death-penalty cases.

Question presented

1. Does the Eighth Amendment require that a capital-sentencing jury be affirmatively instructed that mitigating circumstances need not be proven beyond a reasonable doubt? 2. Does a trial court's decision not to sever the sentencing phase of a joint trial violate the defendants’ Eighth Amendment rights to an individualized sentencing determination?

What the Court decided

Holding

No. 14–449, 300 Kan. 340, 329 P. 3d 1195; No. 14–450, 300 Kan. 1, 331 P. 3d 544; and No. 14–452, 299 Kan. 1127, 329 P. 3d 1102, reversed and remanded.
